Description

Unmanned vehicle, system and method for initiating a fire-extinguishing action

The invention relates to an unmanned vehicle for initiating a fire extinguishing action, a system for initiating a fire extinguishing action and a method for initiating a fire extinguishing action.

Fire detection systems, which are also referred to as fire alarm systems, are known from the prior art. The fire alarm systems are used for the early detection of a fire, in order to initiate countermeasures based on this, such as a fire-extinguishing action.

To detect a fire, so-called fire detectors are used. These are preferably so-called automatic fire detectors. The fire detector can transmit a signal corresponding to the detected fire to a fire alarm control panel. The fire alarm panel can then trigger an alarm signal and / or initiate follow-up actions. Subsequently, the detected fire can be deleted by means of an extinguishing system.

Fire detectors are often installed in hazardous buildings and / or areas. For example, a fire alarm can be installed in a factory building. This can lead to smoke and / or heat developments, which are due to common production processes. It may therefore happen that an apparent fire is detected by the fire detector, although in fact there is no fire. In other words, a faulty detection by means of a fire detector can occur. This leads to the Transmission of an appropriate signal from the fire alarm to the fire alarm panel then a so-called false alarm. In practice, it has been found that fire detectors often detect a fire by mistake even though there is no fire. Thus, it can come in appropriate frequency to false alarms.

If, due to a false alarm, an extinguishing action is initiated by means of an extinguishing system, damage can occur in the area which is erroneously extinguished by the extinguishing system. In order to avoid such damage, after the alarm signal is received in the fire alarm panel, there is often a visit to an area for which the fire detector has detected the fire to verify that the fire has been correctly or possibly mistakenly detected by the fire detector. The person entering then reports the result of the check to another person who has access to the fire alarm panel by means of an input unit. If the fire has been verified or confirmed by the procedure explained above, a follow-up action, such as the extinguishing of the fire, is based on this. If, on the other hand, the person responsible for the fire allegedly does not confirm the fire which was detected by the fire detector, this is therefore an incorrect recognition, then this information is also transmitted to the further person at the fire alarm control panel, so that the follow-up action, such as the deletion of the alleged fire , can be prevented. This offers the advantage that possible consequential damage can be prevented by an unnecessary deletion.

A certain time may elapse between the arrival of a signal from a fire detector and a detected fire and the arrival of the person at the location for which the fire detector has detected the fire. In this case, the duration of the specific time can be different in length, in particular depending on the location for which the fire was detected and who is responsible for the said inspection. In order to avoid damage to property and / or personal injury in an actual fire, however, a timely fire fighting would be desirable because an actual fire with continuous time can often lead to exponential increases in property and / or personal injury.

Against this background, it is known from the prior art to provide permanently installed cameras for monitoring areas that are also monitored by fire detectors. If a fire is detected by a fire detector, can by means of A camera to be checked whether a corresponding fire actually prevails or not. Due to the high cost of purchasing and / or installing dedicated, fixed cameras, as well as legal restrictions on the protection of such video data, such cameras are rarely used.

Another disadvantage is seen in a stationary installed extinguishing system, as it is often used in the prior art. Because such an extinguishing system requires a high effort to install, which causes correspondingly high costs. In addition, often arise after installation, a non-negligible maintenance. Furthermore extinguishing agents are to be provided in accordance with local stationary for a stationary extinguishing system. As extinguishing agent, for example, water can be used. In this case, the stationary extinguishing system may have multiple nozzles to deploy the water in a fire. The nozzles of a stationary extinguishing system are fixed. Therefore, the stationary extinguishing system often allows no targeted application of water or extinguishing agent.

US 8 973 671 B2 discloses an indoor fire-extinguishing robot which has the ability to detect fires early, for example with smoke detectors and fire extinguishing using entrained extinguishing containers with extinguishing agent and nozzles. The fire-fighting robot is able to climb stairs. It is equipped with multiple thermal insulation technology and can withstand very high temperatures up to 700 Celsius for 60 minutes. The fire-extinguishing robot can communicate with trapped and injured persons in the fire area and sends video and audio information about the fire to a controller. No signal exchange with stationary installed fire detectors or a central unit is described. The disclosed fire-extinguishing robot can automatically detect a fire or be notified by a user who can also control it with a remote control.

WO 99/39773 A1 discloses an unmanned vehicle for fire fighting, trained as a boat, and capable of safely and effectively extinguishing a fire on a ship. The fire extinguishing takes place with the help of alignable fire extinguishers, which are on a Fire tower are installed. The deletion is controlled remotely from a remote, secure area.

The published patent application DE 199 50 848 A1 describes a mobile robot for monitoring rooms, in particular for use for fire detection or early fire detection and for combating sources of fire. The robot has a unit for non-contact object detection and object measurement and a the

Thermal radiation of the object detecting detector, such as an infrared camera. The detector signals can be evaluated on the basis of the triangulation method. DE 199 50 848 A1 further discloses a platform for fire fighting with a dispensing unit, by means of which a mass flow, preferably of solid, liquid or gaseous media, can be applied to the object. Also, this robot has no devices that allow a signal exchange with stationary installed fire detectors that detect a fire early, or with a central unit, in particular a fire alarm panel.

US Pat. No. 5,860,479 discloses an unmanned aerial vehicle for firefighting, which is connected to a water supply hose.

The invention is therefore based on the object of providing a vehicle, a system and / or a method which enables a cost-effective, rapid and / or versatile checking of a fire detected by a fire detector as well as a rapid deletion of the fire.

According to a first aspect of the invention, said object is achieved by an unmanned vehicle having the features of claim 1. Advantageous embodiments of the unmanned vehicle and preferred embodiments of the unmanned vehicle are set forth in the appended subclaims and in the description below.

An unmanned vehicle for fire extinguishment is proposed. The unmanned vehicle is also referred to as a vehicle. The vehicle has a vehicle sensor unit which is capable of detecting, in particular at least, a fire parameter of a vehicle Vehicle monitoring area is formed. In addition, the vehicle has a vehicle communication unit for signal exchange with a central unit, preferably a fire alarm panel, or with a stationary fire detector, wherein the vehicle communication unit is adapted to receive an instruction signal containing a detected fire, in particular a reference fire condition for a fire alarm monitoring area of the stationary fire detector, and a Destination and / or a destination represented.

In addition, the vehicle has a navigation control unit which is designed to navigate the vehicle based on the received instruction signal, preferably autonomously, to the destination location and / or to the destination area. In addition, the vehicle is configured to display the fire parameter at the destination location or in the target area by means of the vehicle sensor unit as a Verifikationsbrandkenngröße, preferably the fire alarm monitoring area to detect. In addition, the vehicle is designed and / or configured to determine a verification fire state by evaluating the verification fire parameter. In addition, the vehicle is configured and / or configured to initiate a fire-extinguishing action when the verification firing condition has been determined.

Preferably, the vehicle communication unit is a signal receiving unit, or has such.

In a preferred embodiment, the navigation control unit is configured to navigate the vehicle to the destination in such a way that the vehicle monitoring area overlaps the fire alarm monitoring area at the destination location. The detected fire represents the reference fire condition for the fire alarm monitoring area of the stationary fire detector. The vehicle is hereby configured to determine the reference fire condition as a verified reference fire condition, in case the reference fire condition and the verification fire condition at least sufficiently coincide. The vehicle is configured and / or configured to initiate a fire-extinguishing action when the reference fire condition has been determined to be a verified reference fire condition. When an instruction signal is received by the vehicle communication unit of the vehicle, the vehicle receives the information about a detected fire, preferably about the reference fire condition for a fire detector monitoring area. The fire alarm monitoring area is monitored by the stationary fire detector, which is also referred to as a fire alarm. Such a fire detector may be permanently installed in, for example, a building, a building or an object to be protected or in the vicinity thereof to monitor said fire alarm monitoring area. The fire detector may be, for example, a fire gas detector, a smoke detector, a heat detector, a flame detector or another known from the prior art fire detector. The fire detector monitoring area can therefore preferably be an area assigned to the fire detector. The fire detector may have a fire detector sensor unit. The fire detector sensor unit is designed to detect a fire parameter, which is referred to here as a reference fire parameter. A fire parameter can basically represent and / or characterize at least one physical and / or chemical property of a combustion process. For a preferred embodiment, it can be provided that the fire detector sensor unit is designed in the manner of a multi-sensor unit or with a plurality of, in particular, different sensors. The sensor signals and / or sensor data of the multisensor or the plurality of sensors can be evaluated by means of a preprocessing unit, in particular based on stored signal patterns or data, in order to subsequently detect a corresponding number of fire characteristics, which are referred to as reference fire parameters. In the evaluation, in particular neural networks can be used. For this purpose, the fire detector sensor unit can be designed and / or configured accordingly.

Depending on the intended use, the fire detector sensor unit may be designed to detect a correspondingly suitable reference fire parameter. An example of a reference combustion parameter is the temperature. In this case, the fire detector sensor unit can thus be designed to detect a temperature of the fire detector monitoring area. However, a reference combustion parameter that can be detected by the fire detector sensor unit can also be a smoke concentration and / or a concentration of at least one predetermined gas. In addition, the fire be designed based on the detected reference fire characteristic for determining a reference fire condition. For this purpose, the reference fire parameter can be evaluated by the fire detector. For evaluation, the fire detector may have an evaluation unit. In this case, the evaluation unit may be designed in the manner of a data processing unit for evaluating the reference fire parameter. The reference fire state determined by the fire detector can correspond, for example, to a fire, a fire precursor and / or a smoldering fire.

A fire may be understood to mean a combustion process associated with a light phenomenon, such as a fire, a flame, a glow, a glow, and / or a spark. A smoldering fire can be understood to mean a combustion process without a light phenomenon. A precursor fire can be understood to mean a process in which thermal decomposition products are formed, for example by means of a reduction reaction and / or a homolytic cleavage. In the case of the corresponding thermal decomposition, preferably no oxidation or no oxidation reaction takes place. In practice, it may happen that the previously described fire, the smoldering fire and the fire precursor are referred to as "fire".

When a reference fire condition has been determined by the fire detector, the fire detector may transmit a fire alarm signal representing the reference fire condition to a central processing unit, such as a fire alarm panel. In turn, the central processing unit may be configured and / or configured to transmit the instruction signal to the vehicle, wherein the instruction signal represents at least the reference fire condition for the fire alarm monitoring area.

By receiving the instruction signal, the vehicle thus receives information as to whether a fire corresponding to the reference fire state, corresponding fire precursor and / or corresponding smoldering fire is present in the fire alarm monitoring area.

The vehicle has the advantage that a reference fire condition determined by a fire detector is determined by means of a verification fire condition determined by the vehicle can be checked, so that, if the states mentioned at least sufficiently agree, a verified reference fire condition can be determined. This can be done without human intervention, so that the determination of the verified reference fire condition can be carried out particularly quickly and safely. If the reference firing condition has been determined to be a verified reference firing condition, it may serve as a reliable basis for initiating a fire-extinguishing action, such as deleting a fire in the fire alarm monitoring area.

In addition, the vehicle is inexpensive and at the same time very flexible and / or versatile. Because the vehicle can navigate to any destinations or destinations, especially driving. Thus, the vehicle may be used to detect a verification fire characteristic of a fire alarm monitoring area of any fire detector. Because the vehicle is mobile and thus not stationary bound and / or arranged. It is therefore not necessary to provide for each fire alarm monitoring area an additional monitoring system, such as a stationary installed camera system, to verify or verify a reference fire condition determined for a fire alarm monitoring area. Due to the low cost of only one vehicle and due to the mobility of the vehicle, this is particularly cost effective and flexible.

Another advantage of the vehicle is that the detected fire, preferably the reference fire condition can be checked in close proximity to the fire alarm monitoring area, so that a corresponding verification of the reference fire condition and possibly a fire extinguishing action can be particularly fast after the arrival of the vehicle at the destination.

The vehicle is designed as an unmanned vehicle. In this case, the vehicle may be designed as an unmanned land vehicle or as an unmanned aerial vehicle. If the vehicle is designed as an unmanned land vehicle, this can preferably be designed as a robotic vehicle. If the vehicle is designed as an unmanned aerial vehicle, this can be designed, for example, as a drone. As an unmanned vehicle this comes without personnel. In this case, the unmanned vehicle preferably independently, independently and / or remotely controlled operate and / or navigate. If the unmanned vehicle is designed as a robot vehicle, this can also be designed in the manner of an autonomous, mobile robot.

The vehicle includes a sensor unit called a vehicle sensor unit. Preferably, the vehicle sensor unit is designed as a sensor or has a sensor. The vehicle sensor unit is designed to detect a fire parameter, preferably at least one fire parameter, of a vehicle monitoring area. A fire parameter can basically represent and / or characterize at least one physical and / or chemical property of a combustion process. The vehicle monitoring area is preferably an area assigned to the vehicle sensor unit. Thus, the vehicle sensor unit can be used to monitor the vehicle monitoring area for a fire, a fire precursor and / or a smoldering fire. For a preferred embodiment it can be provided that the vehicle sensor unit is designed in the manner of a multi-sensor unit or with a plurality of, in particular different, sensors. The sensor signals and / or sensor data of the multisensor or the plurality of sensors can be evaluated by means of a preprocessing unit, in particular based on stored signal patterns or data, in order to subsequently detect a corresponding number of fire characteristics. In the evaluation, in particular neural networks can be used. For this purpose, the vehicle sensor unit can be designed and / or configured accordingly. The detection of the fire parameter by means of the vehicle sensor unit can be controlled by the vehicle and / or continuously or discretely, for example at predetermined time intervals, take place. In addition, it is preferably provided that the vehicle monitoring area is assigned stationary and / or vehicle-fixed to the vehicle sensor unit and / or the vehicle. If the vehicle is moving, a corresponding movement of the vehicle monitoring area can take place.

Depending on the intended use, the vehicle sensor unit can be designed to detect different fire characteristics. An example of a fire characteristic is, for example, the temperature. In this case, the vehicle sensor unit may be configured to detect the temperature of the vehicle monitoring area. The vehicle sensor unit may be formed in this case as a temperature sensor unit or as a temperature sensor. The same applies to the following possible fire characteristics. Thus, a fire parameter, for example, a smoke concentration, which is also referred to as smoke particle concentration, a concentration of a predetermined gas, a concentration of a plurality of predetermined gases, a concentration of at least one thermal decomposition product or one, in particular average, amplitude of a predetermined electromagnetic spectral range. A fire characteristic may also be a change and / or slope value of at least one of the aforementioned fire characteristics. For example, the fire parameter may be a temperature gradient or a concentration gradient. For detecting a concentration of a gas, the vehicle sensor unit may be, for example, a gas sensor unit or a gas sensor. If the vehicle sensor unit is used to detect an amplitude of a predetermined electromagnetic spectral range, the vehicle sensor unit can be designed as an optical and / or photoelectric sensor unit for detecting a corresponding, in particular average, amplitude of the predetermined electromagnetic spectral range. This spectral range can originate, for example, from the ultraviolet, the infrared and / or the near-infrared range. The fire characteristic detected by means of the vehicle sensor unit therefore provides information as to whether a fire, a fire precursor or a smoldering fire prevails in the vehicle monitoring area.

In addition, the vehicle has a vehicle communication unit for receiving an instruction signal. The vehicle communication unit may be designed to be detachably connected and / or coupled to a signal line, so that the instruction signal can be transmitted to the vehicle communication unit by means of the signal line and the instruction signal can then be received by the latter. Preferably, however, it is provided that the vehicle communication unit is designed as a radio vehicle communication unit. Thus, the vehicle communication unit can receive the instruction signal telemetrically or by radio.

The instruction signal receivable by the vehicle communication unit represents at least one reference fire state of a fire alarm monitoring area. Of the Reference fire condition is a fire condition. Preferably, the reference fire state corresponds to a fire, a fire precursor or a smoldering fire. The reference firing state therefore provides information as to whether a fire, a fire precursor or a smoldering fire prevails in the fire alarm monitoring area. However, the reference fire condition is not determined or determined by the unmanned vehicle. Rather, the vehicle receives by means of the vehicle communication unit, the instruction signal, which represents at least the reference fire condition. Thus, the unmanned vehicle, the reference fire condition, or the information about it, provided by means of the instruction signal.

The instruction signal also represents a destination for the vehicle. The destination may be a location coordinate, have a location coordinate, represent a limited space, and / or represent an area. In addition, the destination may also have further location information, such as orientation information for the vehicle and / or for the vehicle sensor unit of the vehicle.

The instruction signal also preferably represents a destination area for the vehicle. The target area may represent a limited space, and / or represent an area. Preferably, the destination is in the destination area. By propagating the detected fire, it may be necessary to verify the detected fire at the destination, preferably in the immediate vicinity of the fire detector monitoring area, preferably by detecting the Verifikationsbrandkenngröße the vehicle sensor unit, but in the target area.

In addition, the vehicle has a navigation control unit. The navigation control unit is configured and / or configured to navigate the vehicle based on the instruction signal, in particular based on the destination signal represented by the instruction signal, to the destination, in particular to navigate controlled. The received instruction signal informs the vehicle and in particular the navigation control unit of the desired destination. The instruction signal can simultaneously serve as a command for starting the navigation to the destination and / or be evaluated and / or interpreted in a corresponding manner by the vehicle and / or the navigation unit. Another command to start the navigation using the Navigation control unit to the destination can thus be omitted. Navigation is preferably understood as steering, moving, driving or flying. Particularly preferably, the vehicle and / or the navigation control unit is designed and / or configured to navigate autonomously and / or independently to the destination based on the transmitted instruction signal, and in particular based on the destination represented by the instruction signal. Preferably, the destination is at a predetermined distance from the fire alarm monitoring area. Alternatively, it may be provided that the destination is in the fire alarm monitoring area. In addition, the navigation control unit may be designed to receive signals from a navigation satellite and / or from a dummy track. Based on these signals and the instruction signal, or destination represented by it, the navigation control unit is preferably designed to navigate the vehicle to the destination location in a controlled manner. Thus, after receiving the instruction signal, the vehicle can preferably autonomously and / or autonomously navigate to the destination.

The instruction signal representing the detected fire, preferably the reference fire condition and the destination, is preferably transmitted to the vehicle only in the event the reference fire condition requires verification. The reference firing condition preferably requires verification when the reference firing condition corresponds to a fire requiring firefighting action. In addition, it may be provided that the reference firing state preferably requires verification if this corresponds to a fire, a precursor fire or a smoldering fire. Even a precursor fire can develop into a fire and then requires, as well as a smoldering fire, a fire extinguishing action. The verification, ie the renewed detection of a fire at the destination or in the target area, preferably in the fire detector monitoring area by means of the vehicle sensor unit has the advantage that a fire extinguishing action takes place only if there is no doubt about a fire. This has the advantage that no initiation of the fire extinguishing action takes place when the first fire detection, preferably the detected reference fire condition, represents a false alarm and thus consequential damage is avoided. An advantageous embodiment is characterized in that the central unit is configured so that a reference fire condition, ie a current reference fire condition, requires verification if previously, at most with a predetermined maximum time interval, at least one reference fire condition of the fire detector or another Fire alarm was transmitted to the central unit.

Thus, it may be provided that a reference firing state transmitted to the central unit initially requires no verification until at least one further reference firing state is transmitted to the central unit. The two reference fire conditions can come from the same fire detector. Alternatively, it can be provided that the two reference fire states originate from different fire detectors, each fire detector being designed to detect an associated reference fire characteristic of the same fire alarm monitoring area. If, for example, a first fire detector detects a first reference fire parameter for a fire detector monitoring area and based on the first reference fire parameter, for example, a fire precursor is determined as the first reference fire condition, then a first fire alarm signal can be transmitted to the central unit, wherein the first fire alarm signal represents the first reference fire condition. Due to the preferred configuration of the central unit, no verification is provided for the first reference firing state. An instruction signal is then not transmitted to the vehicle yet. However, if the first fire alarm or a second fire alarm detects a second reference fire parameter for the same fire alarm monitoring area and a second reference fire state is determined based on the second fire parameter, a second fire alarm signal can be transmitted to the central unit, the second fire alarm signal representing the second reference fire state. In this case, the second reference fire state, for example, correspond to a fire. If the first fire alarm signal and the second fire alarm signal are transmitted to the central unit to each other within the predetermined, maximum time interval, it is provided on the basis of the preferred configuration of the central unit that the second reference fire condition requires verification. Therefore, then also the transmission of the instruction signal to the vehicle. If the reference firing state now requires verification, the instruction signal, in particular from a central processing unit, can be sent to the vehicle and / or transmitted.

If a corresponding fire alarm signal, which represents the reference fire state, has been transmitted to the central unit, it may be configured and / or configured to determine the destination based on the transmitted fire alarm signal. For example, if each of a plurality of fire detectors is connected to the central unit by means of a signal line connection in order to be able to transmit a corresponding fire alarm signal to the central unit, the central unit can be designed and / or configured to determine the fire detector which has transmitted the fire alarm signal , Based on the particular fire detector, the central unit may be configured and / or configured to determine the respective destination. For this purpose, data may be stored by the central unit, which represent a destination for each of the fire detectors, wherein the central unit is formed using said data for determining the respective destination corresponding to the fire detector, which has transmitted the fire alarm signal. If there is now a transmission of a fire alarm signal from one of the fire detectors to the central unit, the central unit can determine the destination relevant for the respective fire detector by means of the data.

The destination represented by the instruction signal may therefore be predetermined and / or chosen such that the vehicle monitoring area is in sufficient overlap with the fire alarm monitoring area when the vehicle is at the destination. If the vehicle has been navigated to the destination, the vehicle monitoring area and the fire detector monitoring area are sufficiently overlapping. For at the destination, the vehicle is preferably at a predetermined distance to the fire alarm monitoring area or even in the fire alarm monitoring area. Since the vehicle monitoring area is correspondingly co-moving with the navigation of the vehicle, a sufficient overlap of the vehicle monitoring area with the fire detector monitoring area takes place when the vehicle is at the destination. Thus, the vehicle monitoring area may also be referred to as a vehicle-mounted or vehicle sensor unit-fixed monitoring area. The vehicle monitoring area can therefore be characterized in that it can be detected by the vehicle sensor unit.

Preferably, it is envisaged that the vehicle surveillance area and the fire alarm monitoring area then overlap sufficiently if at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90% or 100% of the vehicle surveillance area is in overlap with the fire alarm monitoring area. For the area in which the vehicle monitoring area and the fire detector monitoring area overlap, a fire parameter can be detected by means of the vehicle sensor unit. In this sense, the vehicle is preferably designed and / or configured to detect the fire characteristic at the destination by means of the vehicle sensor unit as the verification fire parameter of the fire detector monitoring area, at least for the part of the fire detector monitoring area that overlaps with the vehicle monitoring area. With respect to the verification fire characteristic, the explanations, the advantages and / or effects are analogously referred to in an analogous manner, as they have been discussed for the fire characteristic. The Verifikationsbrandkenngröße therefore provides information on whether prevails in the fire alarm monitoring area, at least for the part of the fire alarm monitoring area that is in overlap with the vehicle monitoring area, a fire, a fire precursor or a smoldering fire.

Based on the, in particular at least one verification fire parameter, the vehicle is designed to determine a verification fire condition. For this purpose, the verification fire parameter is evaluated by the vehicle. If a plurality of Verificationbrandkenngrößen detected, the vehicle may be configured to determine the (a) Verification fire state based on the multiple Verifikationsbrandkizes. For evaluation, the vehicle may have an evaluation unit. The evaluation unit can be designed in the manner of a data processing unit for evaluating the, in particular at least one, verification firing parameter. The previous explanations for determining a fire state based on a fire parameter are analogously for the determination of the Verification fire state based on, in particular at least one, Verification firing parameter reference. If the verification firing state is determined, this therefore forms a second or further fire state in addition to the reference firing state for the fire alarm monitoring area. Since the vehicle has already been provided with the reference fire state by means of the instruction signal, the vehicle now has two fire states, namely the reference fire state and the verification fire state, for the fire alarm monitoring area.

For a preferred embodiment it can be provided that the vehicle sensor unit is designed in the manner of a multi-sensor unit or with a plurality of, in particular different, sensors. The sensors or the multi-sensor unit can be designed to determine a plurality of fire characteristics, these fire characteristics being referred to as Verificationbrandkenngrößen. Based on the aforementioned detected firing characteristics, the vehicle may be configured to determine a verification firing condition. For this purpose, the verification fire parameters are evaluated by the vehicle. For evaluation, the vehicle may have an evaluation unit. The evaluation unit can be designed in the manner of a data processing unit for evaluating the verification fire parameters. In the evaluation, in particular neural networks can be used.

In addition, the vehicle is configured to determine the reference fire condition as a verified reference fire condition in the event that the reference fire condition and the verification fire condition at least sufficiently coincide. Thus, the vehicle may be configured to evaluate the reference fire condition and the verification fire condition. For this purpose, the vehicle may have one or the evaluation unit. This applies, in particular, to the evaluation of whether the reference firing state and the verification firing state at least sufficiently coincide. A match may be in the reference fire state and the verification fire state, for example, when the reference fire state and the verification fire state are exactly coincident and / or when the verification fire state corresponds to a fire. In the second case, the reference firing state may correspond, for example, to a smoldering fire or a precursor fire. Thus, a sufficient match between the Reference fire state and Verifikationsbrandzustand be present when the Verification fire state corresponds to a fire and the reference fire state corresponds to a smoldering fire or a fire precursor. However, even though the reference firing state and the verification firing state may not exactly match, a sufficient match may be assumed when the verification firing state represents a fire, for example, since the firing process may have evolved in the transitional period while the vehicle is navigating to the destination. A match, and thus also a sufficient match, may be present, for example, if the reference firing state and the verification firing state match. This is the case, for example, if the reference firing state and the verification firing state respectively correspond to a fire, a precursor fire or a smoldering fire.

If the reference combustion state and the verification fire state at least sufficiently agree, the verified reference fire state is determined by the vehicle. The verified reference firing state can correspond to a fire, a precursor fire and / or a smoldering fire or represent the fire, the fire precursor and / or the fire. The verified reference fire condition therefore provides reliable information as to whether a fire, a fire precursor or a smoldering fire actually prevails in the fire alarm monitoring area.

In addition, the vehicle is configured to initiate a fire-extinguishing action when the reference fire condition has been determined to be a verified reference fire condition. Thus, the vehicle may be configured to emit a signal to initiate the fire-extinguishing action, which signal represents a request for a fire extinguishment. For example, the vehicle may send the signal to another unit that is at least indirectly configured to perform the fire extinguishing. Thus, the vehicle can serve to initiate the fire-extinguishing action by sending the corresponding signal. The further unit may be, for example, a fire alarm panel and / or a fire alarm and extinguishing control center. If the signal from the vehicle is received by such a unit, a corresponding fire extinguishment in the fire alarm monitoring area can be carried out, in particular by the Fire alarm panel is at least indirectly and / or controlled by the extinguishing control panel extinguishing system to deploy extinguishing agent in the fire alarm monitoring area. Alternatively or additionally, the vehicle itself may be designed to extinguish a fire. For example, the vehicle may be configured to dispense extinguishing agent when the reference fire condition has been determined to be a verified reference burn condition. In this case, the vehicle can be configured and / or configured to deploy the extinguishing agent from the vehicle in the fire detector monitoring area, so that, if necessary, a fire, a fire precursor and / or a smoldering fire can be extinguished there.

An advantageous embodiment of the vehicle is characterized in that the vehicle is designed as an aircraft, in particular a robotic vehicle. A land vehicle has the advantage that it can be made particularly robust. In the event of a collision with an obstacle, this usually does not necessarily lead to such a serious defect that the land vehicle can not continue or navigate. Rather, after a possible collision with an obstacle, the land vehicle can then bypass it to continue navigating to the destination. To be particularly advantageous, a robotic vehicle has been found to be a land vehicle. The robotic vehicle preferably means an unmanned robotic land vehicle. The land vehicle can then travel and / or navigate without human crew. This allows a particularly secure detection of Verifikationsbrandkenngröße without fear of personal injury.

A further advantageous embodiment of the vehicle is characterized in that the vehicle is designed as an aircraft, in particular a drone. If the vehicle is designed as an aircraft, this can overcome obstacles that are particularly easy and fast in order to reach the destination. This permits a particularly timely determination of the verification fire parameter or of the verification firing state, so that it can be found correspondingly quickly that the reference fire condition is to be determined as a verified reference fire condition or not. Particularly preferably, the aircraft is designed as a drone or unmanned aerial vehicle. The aircraft can in this case navigate to the destination without human crew. Personal injury to a non-existent crew can therefore be excluded. Thus, a reference fire condition can be verified very secure. A particularly advantageous embodiment of the aircraft is for example a multicopter, such as a quadrocopter or an octocopter. Such multicopters offer the advantage of being able to hold and / or stand in any position in space. This allows a particularly simple navigation to the destination, so that the vehicle monitoring area and the fire alarm monitoring area overlap sufficiently. Alternatively, the aircraft may also be formed by an aircraft and / or a helicopter.

A further advantageous refinement of the vehicle is characterized in that the vehicle has a fire-extinguishing unit for extinguishing a fire, wherein the vehicle is designed to execute the fire-extinguishing action using the fire-extinguishing unit. The fire-extinguishing unit may be at least partially formed by the vehicle. Thus, the fire-extinguishing unit may be formed integrally with or from the vehicle. The fire-extinguishing unit can be designed for direct and / or indirect extinguishment of a fire. For directly extinguishing a fire, the fire-extinguishing unit can be designed to eject and / or spray an extinguishing agent. For the indirect extinguishing of a fire, extinguishing agent can be provided by the fire extinguishing unit, preferably under pressure. For example, the fire-extinguishing unit can have an outlet connection with which extinguishing agent can be provided. Extinguishing agents can be understood as meaning, for example, gaseous extinguishing agents, such as non-combustible gases, extinguishing powder, extinguishing foam, and / or liquid extinguishing agents, such as water and / or aqueous solutions. For example, BC powder, ABC powder and / or metal fire powder can be used as extinguishing powder. A non-combustible gas is, for example, carbon dioxide (C0 ₂ ). As a liquid extinguishing agent, for example, the liquid, synthetic extinguishing agent FK-5-1-12 (C ₄ F ₉ OCH ₃ ) can be used. This is the known under the brand name NOVEC 1230 extinguishing agent, which is in the ASHRAE nomenclature FK 5 -1-12. It is listed in standards NFPA 2001 and ISO 14520 and is also represented by the chemical formulas (C ₄ F ₉ OCH ₃ ) or l, l, l, 2,2,4,5,5,5-NONAFLUORO-4- ( TRIFLUOROMETHYL) -3-PENTANONE.

The extinguishing agent can be stored in a container associated with the extinguishing agent unit, which is also referred to as an extinguishing agent container. The vehicle now navigates to the Destination and then the verified reference fire condition is determined, a fire extinguishing action by fire extinguishing can be performed by means of fire extinguishing unit. This allows a fast and efficient extinguishing of a fire. For the vehicle is already in the vicinity of the fire alarm monitoring area and can thus extinguish a fire in the fire detector monitoring area directly after the determination of the verified reference fire state. This effectively prevents a corresponding fire process from developing further. In practice it has been shown that therefore can be dispensed with a stationary extinguishing system, which contributes to the reduction of costs. Because the vehicle can carry the extinguishing agent, it often requires no stationary extinguishing system, since the corresponding task is taken over by the mobile vehicle. In addition, damage can be reduced in a fire extinguishing by the extinguishing agent is selectively applied by the vehicle. In summary, the vehicle is cheaper than a stationary extinguishing system and also causes less damage in a fire extinguishing.

An advantageous embodiment of the vehicle is characterized in that the fire-extinguishing unit has a nozzle which is designed for discharging, in particular spraying and / or discharging, an extinguishing agent for extinguishing a fire. In this case, the fire-extinguishing unit can be designed in such a way as to direct and / or convey extinguishing agent under pressure to the nozzle, so that the extinguishing agent can be discharged, in particular sprayed out and / or ejected, by means of the nozzle. If the extinguishing agent is, for example, water or an aqueous solution, then the corresponding extinguishing agent can be sprayed out by means of the nozzle. If the extinguishing agent is an extinguishing agent powder, then this can be expelled, for example, by means of the nozzle. By means of the nozzle of the fire-extinguishing unit, the fire-extinguishing unit of the vehicle is therefore particularly preferably suitable for the direct extinguishing of a fire.

An advantageous embodiment of the vehicle is characterized in that the fire-extinguishing unit has an externally accessible output connection for the provision of extinguishing agent which can be coupled to a counterpart connection of a stationary extinguishing device in order to provide extinguishing means for the extinguishing device. If the verified reference fire condition has been determined by means of the vehicle, then it can be provided that the output terminal of the fire extinguishing unit is subsequently identified with is coupled to the mating terminal of the stationary erasing device. This coupling makes it possible to transmit extinguishing agent from the vehicle, in particular from the associated fire extinguishing unit, to the stationary extinguishing device or to make it available. Therefore, providing may mean pumping, routing and / or conveying. In this case, the extinguishing agent can be applied pressurized and / or made available. The stationary extinguishing device can be designed to deploy the extinguishing agent in the fire detector monitoring area, in particular to eject and / or spray it. With regard to the application, reference is made to the preceding explanations in an analogous manner. In particular, the dispensing is a pressurized dispensing. The stationary extinguishing device is also referred to as extinguishing system. Preferably, the extinguishing device is characterized by the mating connector, at least one nozzle and a pipeline network extending between the mating connector and the at least one nozzle. For this purpose, the pipeline network can have at least one extinguishing medium line, but preferably a plurality of extinguishing medium lines coupled to one another. If the extinguishing device has, for example, a plurality of nozzles, the pipeline network can be designed in such a way by means of the extinguishing medium lines in order to guide extinguishing agents from the counterpart connection to the nozzles. If extinguishing agent is now conveyed from the outlet connection of the vehicle to the counterconnection of the extinguishing device, the pipeline network directs the extinguishing agent to the nozzles, which then discharge the extinguishing agent in order to extinguish a fire, preferably in the fire detector monitoring area. Thus, the extinguishing device is preferably configured to extinguish a fire in the fire detector monitoring area, preferably by conveying extinguishing agent through the counter connection and the pipe network to the at least one nozzle. If the fire-extinguishing unit of the vehicle has the output connection accessible on the outside, then the fire-extinguishing unit or the vehicle can also be used and / or designed for the indirect extinction and / or indirect initiation of a fire-extinguishing action of a fire.

An advantageous embodiment of the vehicle is characterized in that the vehicle sensor unit has a camera. The camera can be designed as an optical camera for detecting a, in particular optical, image. Therefore, by means of the camera, a light phenomenon, such as a fire and / or a flame, can Burning process are detected, the camera is preferably designed to detect a color temperature of the light phenomenon and / or a temperature of the light phenomenon as a fire characteristic. Furthermore, it can be provided that the camera is designed as a thermal imaging camera for capturing a thermal image. In this case, the thermal imaging camera can be designed to detect infrared radiation. Thus, the camera for detecting a temperature, in particular a maximum temperature and / or a mean temperature, be formed, wherein the detected temperature preferably forms the fire characteristic. If the reference firing state for the fire alarm monitoring area has been determined, for example by means of a fire gas detector or a smoke detector, in each case as an embodiment of the fire detector, the camera can provide the vehicle sensor unit with the advantage that the verification fire parameter is detected by a different measuring principle than a reference fire parameter by means of the fire gas detector or of the smoke detector. In other words, the fire detector sensor unit of the fire detector and the vehicle sensor unit of the vehicle can be based on different measurement principles, which allows a particularly reliable verification of the reference fire condition.

An advantageous embodiment of the vehicle is characterized in that the vehicle is formed at the destination by means of the vehicle sensor unit for determining a fire location. The fire location is preferably the location of a fire source of the fire, the fire precursor and / or the smoldering fire in the fire alarm monitoring area. If, for example, a camera is used for the vehicle sensor unit, which is designed to acquire an image, in particular an optical image and / or a thermal image, then the vehicle can be designed to determine the location of the fire based on the image. For this purpose, the vehicle may be designed in such a way as to identify in the image the point which corresponds to the highest temperature, in particular an illustrated light phenomenon. Based on this identified point and the known destination, the vehicle may be configured to determine the location of the fire. Furthermore, it can be provided that the vehicle is designed to rotate and / or pivot the vehicle sensor unit at the destination to capture sensor data by means of the vehicle sensor unit to different twisting and / or pivoting positions, the fire location based on the detected sensor data and the known Destination by means of Vehicle is determinable. For example, the vehicle may be designed to receive a plurality of images at different locations of rotation and / or pivoting of a camera of the vehicle sensor unit at the destination, and to determine the location of the fire by evaluating the images and taking into account the destination.

A further advantageous refinement of the vehicle is characterized in that the vehicle is configured to determine the location of the fire on the basis of a fire parameter recorded at the destination. For example, the vehicle may be configured to determine the location of the fire at the destination based on the at least one detected fire characteristic. If, for example, a line camera is used as the camera for the vehicle sensor unit, a corresponding image captured by the line camera can be used to determine the location of the fire, and thus to determine the source of the fire. From the image acquired by means of the line scan camera, for example, the direction to the fire location can be determined by searching the acquired image for a highest color temperature. For this purpose, the vehicle and / or the vehicle sensor unit can be designed accordingly.

A further advantageous embodiment of the vehicle is characterized in that the vehicle is designed to align the vehicle sensor unit in the direction of the fire location. If a fire parameter is now determined by means of the vehicle sensor unit, then this corresponds to the fire in the fire detector monitoring area or in the vehicle monitoring area. A corresponding fire characteristic has the advantage that it can provide information about whether a fire, a fire precursor and / or a smoldering fire is particularly reliable.

A further advantageous embodiment of the vehicle is characterized in that the vehicle is configured to detect the fire parameter or the verification fire parameter when the vehicle sensor unit is oriented in the direction of the fire location. Thus, the vehicle may be configured to detect at the destination the fire characteristic by the vehicle sensor unit as the verification fire characteristic of the fire detector monitoring area only when the vehicle sensor unit is oriented in the direction of the fire location. The Verificationsbrandkenngröße can in this case be particularly sure about whether there is a fire, a fire precursor and / or a smoldering fire. As a result, the reference firing state can also be evaluated with particular certainty and optionally determined as a verified reference firing state.

A further advantageous embodiment of the vehicle is characterized in that the vehicle is designed to align the nozzle such that the extinguishing agent to be sprayed and / or ejected from the nozzle flows in the direction of the fire location in order to extinguish a fire. The alignment of the nozzle can refer to a vertical and / or horizontal tilt angle of the nozzle relative to the vehicle. Thus, the vehicle may be configured to rotate and / or pivot the nozzle in a vertical direction and / or a horizontal direction. It has previously been explained that the vehicle is designed to detect the location of the fire, that is to say preferably the location of the fire in the fire detector monitoring area, when the vehicle is at the destination. Based on the fire location, and preferably also based on the destination location, the vehicle may determine which direction the nozzle is to be pivoted so that the nozzle is oriented toward the fire location. The orientation of the nozzle can be carried out in such a way that the nozzle is aligned directly on the fire. However, it can also be provided that the vehicle is designed and / or configured such that a trajectory of the extinguishing agent to be ejected and / or ejected is taken into account. Because a trajectory of the extinguishing agent is often parabolic. Thus, the vehicle may be designed and / or configured for aligning the nozzle such that a parabolic trajectory of the extinguishing agent is taken into account when aligning the nozzle and / or when discharging extinguishing agent. By the explained alignment of the nozzle, a particularly effective, fast and / or safe extinguishing of a fire in the fire detector monitoring area can take place. This saves extinguishing agent and is particularly useful if the extinguishing agent is provided by the vehicle itself. Because the amount of extinguishing agent can be limited in this case. By aligning the nozzle can also be a very targeted and thus effective deletion of a fire, which favors a quick fire extinguishing, which in turn significantly reduce personal injury and / or property damage or even avoid. A further advantageous embodiment of the vehicle is characterized in that the vehicle is designed and / or configured to independently navigate to an, in particular optimal, extinguishing agent application location based on the fire location.

This extinguishing agent application location is also referred to as optimized extinguishing agent application position.

It may happen that the fire alarm monitoring area and / or the vehicle monitoring area are very large. If, for example, a camera is used for the vehicle sensor unit, then a further remote fire detector monitoring area can be brought into sufficient overlap with the vehicle monitoring area. In this case, the destination may be sufficiently far from the fire alarm monitoring area, and especially from a fire in the fire alarm monitoring area. It may happen that a corresponding distance for an effective extinguishing of the fire is too large. If, for example, extinguishing powder is used as the extinguishing agent, a range or the throwing distance of a corresponding extinguishing extinguishing powder is limited. In this case, it may be appropriate to position the vehicle closer to the fire to clear an effective extinguishment of a fire in the fire alarm monitoring area. As previously explained, the vehicle may be configured to determine the location of the fire. In addition, the information about the destination in the vehicle is known.

Preferably, extinguishing agent ejection data, for example the throwing distance and / or preferably the spray pattern of the extinguishing agent to be dispensed, in particular to be sprayed and / or ejected, are also stored by the vehicle for each extinguishing agent used. The vehicle is in particular designed and / or configured on the basis of the extinguishing agent discharge data, taking into account the nozzle construction, the diameter of the extinguishing agent outlet opening and / or the pressure of the extinguishing agent in the fire extinguishing unit and / or in front of the extinguishing agent outlet opening and preferably using the previously determined fire location an extinguishing agent application location , also referred to as optimized extinguishing agent application position, so that one of the Fire extinguishing unit, and preferably from one of the fire-extinguishing unit associated nozzle, auszubringendes, in particular sprayed and / or ejected extinguishing agent can flow to the fire or optimally covered. This ensures an effective, fast and / or safe extinguishing of the fire with an optimized amount of extinguishing agent. Thus, the fire can be extinguished in this case with the least possible extinguishing agent and at the same time in a particularly short time, since it is ensured that the auszubringende, in particular auszusprühende and / or ejected, extinguishing agent targeted the actual fire, especially the associated fire.

An advantageous embodiment of the vehicle is characterized in that the vehicle is designed and / or configured to initiate the fire-extinguishing action when the vehicle is at the extinguishing agent application location. In particular, if the extinguishing agent is provided by the vehicle itself and / or the fire-extinguishing unit of the vehicle itself, it may happen that the amount of extinguishing agent is limited. It is therefore useful to deploy the extinguishing agent, if this actually contributes to the extinction of the fire. This is preferably the case when the vehicle is at the extinguishing agent discharge location. In this context, reference is made to the preceding explanation, advantages and / or effects in an analogous manner. Thus, the available extinguishing agent can be used particularly effectively for extinguishing a fire. Even if the vehicle carries only a limited supply of extinguishing agent, it is therefore possible to extinguish even larger fires, since the vehicle is designed for effective extinguishing, and thus already contributing to the extinction of a fire already a small amount of extinguishing agent.

An advantageous embodiment of the vehicle is characterized in that the fire-extinguishing unit has a, in particular detachable, extinguishing agent container, is stored in the extinguishing agent. If the vehicle now receives the instruction signal, which can preferably be evaluated simultaneously as an instruction to navigate, the vehicle can navigate to the destination without delay, in particular driving or flying. It is therefore not necessary for the vehicle to have to navigate again to another location after the arrival at the destination and an optionally subsequent determination of a verified reference fire condition in order to receive extinguishing agents and / or the actual extinguishing agent action. Rather, the vehicle can start directly at the destination and / or after further navigation to the extinguishing agent Ausplacement with the actual fire extinguishing. This allows the fire to be extinguished without wasting time, preventing a fire from developing. In practice, this can be prevented, for example, that from a combustion process without light appearance, a combustion process with light appearance, ie a fire, arises. In this case, the vehicle may serve, for example, to extinguish the smoldering fire, which is often possible with less use of extinguishing agent. This results in minor personal injury and / or property damage. Preferably, the extinguishing agent container is made as a metal container or as a container made of a non-combustible material. In addition, it can be provided that the extinguishing agent container is detachably coupled to the fire-extinguishing unit and / or the vehicle. Thus, the extinguishing agent container can be replaced for maintenance purposes and / or after an executed deletion action. Thus, the extinguishing agent container can be replaced, for example, by a new, again with extinguishing agent stocked extinguishing agent container, so that the vehicle is operational again in a very short time after a fire extinguishing action. In addition, the detachable attachment of the extinguishing agent container has the advantage that the vehicle can be equipped for different purposes. So it may make sense that for a purpose liquid extinguishing agent is stored in the extinguishing agent container. For another purpose, it may be advantageous if extinguishing agent powder is stored as extinguishing agent in the extinguishing agent container. Thus, by replacing and / or installing a corresponding extinguishing agent container, the vehicle can be adapted for the respective application.

A further advantageous embodiment of the vehicle is characterized in that the extinguishing agent is stored under a predetermined pressure in the extinguishing agent container. The extinguishing agent container may be formed as a pressure-extinguishing agent container. This has the advantage that the extinguishing agent can flow out of the extinguishing agent tank without additional effort. Thus, it requires no additional electrical and / or mechanical power to promote the extinguishing agent from the extinguishing agent tank. For the vehicle, therefore, no separate energy storage or any corresponding consideration in the size of the energy storage for the vehicle. This reduces the weight of the vehicle and / or increases the range of the vehicle when navigating to a destination. This is particularly advantageous when the vehicle is designed as an aircraft, in particular a drone. Because in this case, the pressurized extinguishing agent container can contribute to an increase in range when navigating the aircraft. For the sake of completeness, it should be mentioned here that the predetermined pressure is greater than the atmospheric pressure, in particular at least 2 bar, at least 5 bar, at least 10 bar, at least 25 bar or at least 80 bar greater than the atmospheric pressure.

An advantageous embodiment of the vehicle is characterized in that the fire-extinguishing unit has a coupling device for detachable coupling of an extinguishing agent container. The coupling device thus serves to connect and / or uncoupling the detachable extinguishing agent container. The coupling device can also be designed to hold the extinguishing agent container, in particular when the vehicle is navigating. Thus, the coupling device may comprise arm elements which are designed for gripping, holding and / or releasing the extinguishing agent container. The gripping arms can be controlled by an actuator, which in turn is controlled by the fire-extinguishing unit and / or the vehicle. The vehicle and / or the fire-extinguishing unit can be designed and / or configured accordingly. If, for example, the vehicle is not being used for a fire-extinguishing action, a new extinguishing agent container can be coupled to the fire-extinguishing unit by means of the coupling device so that it can be operational again for a new fire-extinguishing action. In addition, the coupling device may be configured to establish a fluid connection between the extinguishing agent container and the fire extinguishing unit when the extinguishing agent container is coupled, so that then extinguishing agent from the extinguishing agent container by means of the fire extinguishing unit applied, in particular sprayed and / or ejected can be. If a new extinguishing agent container is coupled, it forms the extinguishing agent container of the fire extinguishing unit or of the vehicle.

A further advantageous refinement of the vehicle is characterized in that the fire-extinguishing unit has an extinguishing-agent-generating device for generating the extinguishing agent. For this purpose, the extinguishing agent generation device may for example have a solid and be designed to ignite the solid, so that a gas and / or a Aerosol is formed by a corresponding combustion of the solid, wherein the resulting gas and / or the resulting aerosol serves as an extinguishing agent. The gas and / or aerosol produced by the combustion of the solid is preferably a non-combustible gas or a non-combustible aerosol. In one example, the extinguishing agent generating device may include a pyrotechnic extinguishing kit that may be triggered electrically and / or thermally. For this purpose, the Löschmittelerzeugungsvomchtung be designed accordingly. When the quenching rate is triggered, a reaction process is created which generates the solid aerosol. The resulting solid aerosol is, for example, potassium carbonate. An average particle size of the Feststoffaerosols can be, for example, between 0.5 and 2.5 μιη. If the solid aerosol encounters combustion, in particular a flame, this causes a physical reaction of the solid aerosol with the flame, so that energy is withdrawn from the combustion process. This can also lead to an interruption of a chain reaction of the combustion process. Furthermore, provision may be made for the extinguishing agent generation apparatus to be designed to produce a quenching powder. The extinguishing agent generation apparatus has the advantage that a large amount of extinguishing agent can be produced at the destination and / or at the extinguishing agent application location, so that the vehicle or fire extinguishing unit is designed for this purpose and / or is configured to extinguish even larger fires. In addition, the Löschmittelerzeugungsvomchtung be designed to be particularly compact, resulting in a corresponding compactness of the vehicle. In addition, the Löschmittelerzeugungsvomchtung has a particularly low weight. This is particularly advantageous when the vehicle is designed as an aircraft, in particular a drone.

A further advantageous embodiment of the vehicle is characterized in that the fire-extinguishing unit has an externally accessible input connection which can be coupled to a counterpart connection of a stationary extinguishing agent source, so that extinguishing agent can be conducted from the extinguishing agent source to the vehicle, in particular to the associated fire extinguishing unit. Thus, extinguishing agent can be directed from the extinguishing agent source to the vehicle or the fire extinguishing unit, if the coupling between the input terminal and the counterpart connection is made. Especially with larger fires, it may happen that a stored in an extinguishing agent container Extinguishing media is insufficient to completely extinguish the fire. It has therefore proven to be advantageous if the vehicle or a fire-extinguishing unit has the externally accessible input terminal. When coupled with the mating terminal of a stationary extinguishing agent source, the vehicle may also be configured and / or configured to use extinguishing agent from the extinguishing agent source to extinguish a fire by discharging the extinguishing agent from the extinguishing agent source by means of the fire extinguishing unit, in particular spraying and / or expelling it , will, to extinguish a fire. The extinguishing agent source may for example be a hydrant, which is coupled to a pipeline network, can be promoted on the extinguishing agent, in particular in larger quantities. For example, by means of the mating connection of the stationary extinguishing agent source, liquid extinguishing agent, such as water and / or aqueous solutions, can be conveyed to the input connection of the fire extinguishing unit, so that the liquid extinguishing agent can then be sprayed out by means of the fire extinguishing unit in order to extinguish the fire. In this context, it should be mentioned that the counterpart connection of the stationary extinguishing agent source can be coupled directly to the input connection. Alternatively, provision may be made for connecting hoses to be used to indirectly couple the input port to the mating port of the stationary extinguishing agent source.

When reference is made to coupling, this should preferably be used to produce a fluid-conducting connection. Coupling can therefore also be understood to mean the production of a fluid-conducting connection or a fluid-conducting connection.

A further advantageous refinement of the vehicle is characterized in that the vehicle, in particular the associated fire-extinguishing unit, has a controllable triggering unit, in particular a controllable valve, which is designed to control an extinguishing agent flow to the nozzle and / or the outlet port. In one example, the trip unit may be coupled into fluid communication between the extinguishant canister and the nozzle or output port. Thus, the fluid communication may extend from the extinguishant canister to the trip unit and, in turn, extend to the nozzle and the exit port, respectively. If the extinguishing agent is stored under the predetermined pressure in the extinguishing agent container, by means of Trigger unit, the outflow of extinguishing agent from the extinguishing agent tank to the nozzle or the output port to be controlled. Thus, the trip unit may be configured to enable, prevent, and / or restrict an extinguishant flow to the nozzle and / or the exit port. In an advantageous embodiment, the trip unit is therefore designed as a controllable valve, in particular controllable throttle valve. By means of the controllable release unit, therefore, the time, the duration and / or the quantity of extinguishing agent to be dispensed, in particular to be sprayed and / or ejected, can be controlled. Particularly preferably, the deleting unit and / or the vehicle is designed and / or configured to control the triggering unit. Thus, the trip unit may be used to initiate the fire-extinguishing action when the vehicle is at the extinguishing agent delivery location. Preferably, the trip unit is controlled in response to the verified reference fire condition. Thus, it can be provided that the extinguishing agent flow is throttled when a smoldering fire and / or a fire precursor prevails. This can reduce property damage to a minimum. Because to extinguish a smoldering fire and / or a fire precursor usually less extinguishing agent is necessary than for a fire, so a combustion process with light appearance.

A further advantageous embodiment of the vehicle is characterized in that the fire-extinguishing unit has an extinguishing agent pump for conveying extinguishing agent. For example, the extinguishing agent pump may serve to convey extinguishing agent from the extinguishing agent container to the nozzle and / or the outlet port. The extinguishing agent pump is preferably designed as a controllable extinguishing agent pump. The extinguishing agent pump can be controlled by the fire-extinguishing unit and / or the vehicle. The vehicle or the fire-extinguishing unit can be designed and / or configured accordingly. The use of an extinguishing agent pump may be particularly advantageous if the extinguishing agent is stored, for example, not under pressure in the extinguishing agent container. Furthermore, the extinguishing agent pump may be advantageous in order to increase the range or the throwing distance of the extinguishing agent to be dispensed, in particular to be sprayed and / or ejected. A further advantageous embodiment of the vehicle is characterized in that the vehicle, in particular the associated fire extinguishing unit, is designed to at least use the extinguishing agent pump for controlling an extinguishing agent flow to the nozzle and / or the outlet connection. For example, conveying of extinguishing agent can be interrupted in order to stop the discharge of extinguishing agent.

A further advantageous embodiment of the vehicle is characterized in that the trigger unit and / or the extinguishing pump, in particular fluid-conducting, between at least one of a first group of the extinguishing agent container, the input port and the extinguishing agent generating device, and at least one of a second group of the nozzle and the output terminal is coupled. For example, an input of the trip unit may be connected to the extinguishant container, the input port, and / or the extinguishing agent generating device by means of a fluid power connection to provide extinguishing means to the trip unit. An output terminal of the trip unit may be connected to the nozzle and / or the output terminal by means of a further fluid line connection. The same can apply to the extinguishing agent pump. Furthermore, instead of the triggering unit, the same applies to a combination of the triggering unit and the extinguishing agent pump, if they are connected to one another in series in a fluid-conducting manner by means of a further fluid line connection. An extinguishing agent flow from the extinguishing agent container, the inlet port and / or the extinguishing agent generating device can therefore be directed and / or conveyed to the nozzle and / or the outlet port under the control of the triggering unit and / or the extinguishing pump.

An advantageous embodiment of the vehicle is characterized in that the fire-extinguishing unit has a first, rotationally, pivotally and / or length-adjustable alignment device to which the nozzle is fastened, wherein the vehicle is designed and / or configured to control the first alignment device, to align the nozzle. By means of the first alignment device, the nozzle can thus be rotated, pivoted and / or changed in its height position, preferably so in order to align the nozzle in the direction of the fire. In this case, the vehicle and / or the erasing unit is designed and / or configured to rotate, pivot and / or height adjustment of the first alignment device. Preferably, the first alignment device has a platform to which the nozzle is attached. The platform of the first alignment device may be rotatable and / or pivotable relative to the rest of the vehicle. In addition, the first alignment device may be configured to lift and / or lower the platform in the vertical direction. For this purpose, the first alignment device may comprise at least one controllable actuator, by means of which the platform is rotatable, pivotable and / or height-adjustable relative to the rest of the vehicle. The at least one actuator may be designed to be controllable by the vehicle and / or the fire-extinguishing unit. In addition, the vehicle and / or the fire-extinguishing unit may be designed and / or configured to control the at least one actuator, in particular to achieve a correspondingly controlled turning, pivoting and / or height adjustment of the platform and thus alignment of the nozzle. Thus, it does not necessarily require rotation and / or further navigation of the vehicle to effectively extinguish a fire. Rather, the appropriate orientation of the nozzle sufficient to ensure an effective, fast and / or extinguishing agent-saving fire extinguishing.

A further advantageous embodiment of the vehicle is characterized in that the first alignment device is designed as a first arm device, wherein the nozzle is arranged on an end portion of the first arm device facing away from the vehicle. The first end portion of the arm device may form the previously discussed platform for mounting the nozzle. In addition, the first arm device can have at least one joint in order to be able to pivot and / or rotate arm elements of the arm device relative to each other. In addition, the first arm device may have an example telescopically extendable arm portion. If the first alignment device is configured as a first arm device, the first arm device can be used to position the nozzle above and / or in front of an obstacle, the obstacle being between the vehicle and the source of fire in the fire detector monitoring area. For example, if the vehicle is not immediately able to navigate around the obstacle, the first arm device provides the opportunity to extinguish a fire behind the obstacle. A further advantageous refinement of the vehicle is characterized in that the vehicle has a second, rotationally, pivotally and / or length-adjustable alignment device to which the vehicle sensor unit is fastened, wherein the vehicle is designed and / or configured to control the second alignment device to align the vehicle sensor unit. By means of the second alignment device, the vehicle sensor unit can thus be rotated, pivoted and / or changed in its vertical position, preferably in order to align the vehicle sensor unit in the direction of the fire location. In this case, the vehicle is preferably designed and / or configured to control a rotation, pivoting and / or length adjustment of the alignment device. Preferably, the alignment device has a platform to which the vehicle sensor unit is attached. The platform of the alignment device may be rotatable, pivotable and / or height-adjustable relative to the rest of the vehicle by means of the second alignment device. In addition, the second alignment device may comprise at least one controllable actuator, by means of which the platform is rotatable relative to the rest of the vehicle, pivotable and / or variable in their distance from the rest of the vehicle. The at least one actuator may be designed to be controllable by the vehicle. In addition, the vehicle may be configured and / or configured to control the at least one actuator, preferably to achieve alignment of the vehicle sensor unit, preferably in the direction of the fire location, by appropriately controlled turning, pivoting and / or length adjustment. The vehicle may be preferably configured and / or configured to control the second alignment device to bring the vehicle surveillance area into, in particular sufficient, overlap with the fire detector monitoring area when the vehicle is at the destination. Thus, it does not necessarily require rotation and / or movement of the vehicle to achieve the desired overlap. Rather, this can be ensured by means of the second alignment device or at least with the aid of the second alignment device.

A further advantageous embodiment of the vehicle is characterized in that the second alignment device is designed as a second arm device, wherein the vehicle sensor unit is arranged on an end portion of the second arm device facing away from the vehicle. The end portion of the second arm device can thereby form the previously discussed platform for mounting the vehicle sensor unit. In addition, the second arm device can have at least one joint in order to be able to pivot and / or rotate arm elements of the second arm device relative to each other. In addition, the second arm device may have an example telescopically extendable arm portion. If the second alignment device is configured as a second arm device, the second arm device can be used to position the vehicle sensor unit above and / or in front of an obstacle, the obstacle being between the vehicle and the fire in the fire detector area. For example, should it not be immediately possible for the vehicle to navigate around the obstacle, the second arm device offers the possibility of positioning the vehicle sensor unit in front of or above the obstacle. In this case, the second arm device can be designed to position the vehicle sensor unit over the obstacle, so that the vehicle monitoring area can be brought into, in particular sufficient, overlap with the fire detector monitoring area. The second arm device therefore offers the advantage that a fire alarm monitoring area can also be checked behind an obstacle by means of the vehicle sensor unit if the obstacle is between the vehicle and the fire detector monitoring area.

A further advantageous refinement of the vehicle is characterized in that navigation data are stored by the vehicle, in particular the navigation control unit, which represent a map with possible paths, the navigation control unit being designed using navigation data for navigating the vehicle. If the vehicle, in particular the navigation control unit, receives the instruction signal representing at least the destination, the navigation control unit can navigate the vehicle to the destination using the navigation data in a controlled manner.

A further advantageous refinement of the vehicle is characterized in that the navigation control unit is designed using the navigation data for navigating the vehicle to the destination location and / or the extinguishing agent application location. If the vehicle is used, for example, on a company premises, the navigation data can represent possible routes on the company premises, along which the Vehicle, in particular collision-free, can navigate, in particular to get to the destination and / or the extinguishing agent application location. Thus, a possible collision of the vehicle with objects and / or other stationary placed objects, which can each form obstacles, effectively prevented.

A further advantageous embodiment of the vehicle is characterized in that the vehicle has an obstacle sensor, which is designed to detect an obstacle, in particular in the direction of travel in front of the vehicle. The obstacle sensor can be designed, for example, as a radar sensor. A signal provided by the obstacle sensor may be transmitted to the navigation control unit, so that the navigation control unit is preferably also formed using said obstacle sensor signal for navigating the vehicle to the destination and / or the extinguishing agent application location. Thus, the vehicle can avoid possible, especially only temporarily existing, obstacles particularly effective.

A further advantageous embodiment of the vehicle is characterized in that the navigation control unit is designed using the navigation data for navigating the vehicle to the counterpart connection of the stationary extinguishing device. In this case, the navigation of the vehicle can take place such that the output terminal of the vehicle is coupled to the mating terminal of the extinguishing device, so that a fiuidleitende connection between the output terminal and the mating terminal. The navigation data may thus contain the information about the location of the mating terminal of the stationary extinguishing device. Thus, the vehicle can be navigated to the mating terminal of the stationary extinguishing device by means of the navigation control unit. In this case, the navigation by means of the navigation control unit can be carried out such that an automatic coupling of the output terminal of the fire-extinguishing unit with the mating terminal of the stationary extinguishing device. Alternatively, it can be provided that the navigation of the vehicle by means of the navigation control unit is such that the output terminal is disposed opposite to the mating terminal of the stationary erasing device, so that then in a further step, the coupling of the output terminal to the mating terminal of the stationary erasing device can take place. For this purpose, the vehicle and / or the fire-extinguishing unit may have an actuator in order to connect the Output terminal to the mating terminal of the stationary extinguishing device perform. Alternatively, it can be provided that the coupling of the output terminal to the mating terminal of the stationary extinguishing device takes place manually. If the coupling between the output terminal of the fire extinguishing unit and the counterpart connection of the stationary extinguishing device is established, extinguishing agent can be transferred from the fire extinguishing unit to the stationary extinguishing device and / or conveyed. The preferred features, advantages and / or effects already explained in this context are referred to in an analogous manner.

A further advantageous embodiment of the vehicle is characterized in that the navigation control unit is designed using the navigation data for navigating the vehicle to the counterpart connection of the stationary extinguishing agent source. The navigation of the vehicle by means of the navigation control unit can be carried out such that the input terminal of the vehicle is coupled to the mating terminal of the extinguishing agent source or can be coupled.

The navigation data can thus contain the information about the location of the mating terminal of the stationary extinguishing agent source. Thus, the vehicle can be navigated by means of the navigation control unit to the counterpart connection of the stationary extinguishing agent source. In this case, the navigation can be carried out by means of the navigation control unit such that an automatic coupling of the output terminal of the fire-extinguishing unit with the counter-connection of the stationary extinguishing agent source takes place. Alternatively, it may be provided that the navigation of the vehicle by means of the navigation control unit is such that the output terminal is disposed opposite to the mating terminal of the stationary extinguishing agent source, so that then in a further step, the coupling of the output terminal to the mating terminal of the stationary extinguishing agent source can take place. For this purpose, the vehicle and / or the fire-extinguishing unit can have an actuator in order to carry out the coupling of the output connection to the counter-connection of the stationary extinguishing-agent source. Alternatively, it can be provided that the coupling of the output terminal to the mating terminal of the stationary extinguishing agent source is done manually. Is the coupling established between the output terminal of the fire extinguishing unit and the counterpart connection of the stationary extinguishing agent source, Extinguishing agent can be passed from the stationary extinguishing agent source to the fire-extinguishing unit, transferred and / or promoted.

A further advantageous embodiment of the vehicle is characterized in that the navigation control unit is formed using the navigation data for controlled navigation of the vehicle to an extinguishing agent container depot, in which at least one, provided by the coupling device extinguishing agent container is provided. The navigation data can have the information about the location of the extinguishing agent tank depot. Thus, the navigation control unit can navigate the vehicle under control to the extinguishing agent container depot. At least one extinguishant container may be provided in the extinguishant container depot. The extinguishing agent container preferably stores extinguishing agent in a predetermined amount. In addition, the extinguishing agent container can store the extinguishing agent under a predetermined pressure. Thus, for example, a new extinguishing agent container may be provided in the extinguishing agent container depot. This is particularly advantageous when the vehicle requires more than one extinguishing agent container to extinguish a fire. In this case, the navigation control unit may navigate the vehicle to the extinguishing agent container depot to exchange the extinguishing agent container by means of the coupling device. The vehicle may then again navigate to the destination and / or extinguishing agent deployment location to continue deletion of the fire as previously explained. In addition, provision may be made for the vehicle to navigate to the extinguishing agent container depot by means of the navigation control unit in order to couple an extinguishing agent container suitable for the fire to be extinguished by means of the coupling device, so that the extinguishing agent stored in the corresponding extinguishing agent container can be used particularly effectively for extinguishing the fire.

An advantageous embodiment of the vehicle is characterized in that the vehicle communication unit for receiving a signal, in particular the instruction signal, is formed by a central unit. Thus, the vehicle can receive a signal from the central unit by means of the vehicle communication unit. The central unit may be, for example, a fire alarm control panel and / or fire extinguisher control center or at least be co-formed by it. For example, the vehicle communication unit may receive an instruction signal from the Fire alarm panel received. Furthermore, it can be provided that the vehicle communication unit is used to receive control signals that can be sent from the central unit to the vehicle communication unit. The control signals may be used to at least partially navigate the vehicle to the destination. The control signals received by the vehicle or the vehicle communication unit can be transmitted to the navigation control unit, so that the navigation control unit based on the control signals and / or at least also using the control signals for controlled navigation of the vehicle, in particular to the destination and / or to the extinguishing agent application location , is trained. For example, the navigation control unit of the vehicle can be designed using the navigation data, the instruction signal and the control signals received by the central unit for controlled navigation of the vehicle. By means of the control signals, for example, possible obstacles and / or barriers can be communicated to the vehicle or the navigation control unit, so that the vehicle, or the navigation control unit, taking into account these control signals on an alternative route to the destination and / or another location, such as the destination and / or the extinguishing agent application location.

A further advantageous embodiment of the vehicle is characterized in that the vehicle is designed to generate a trigger signal for the trip unit and to control the trip unit by means of the trigger signal, so that the trip unit releases an extinguishing agent flow to the nozzle and / or the output port when the Trigger unit is controlled by means of the trigger signal. Thus, the vehicle may be configured to control the trip unit to release or prevent an extinguishant flow to the nozzle and / or the exit port. In this case, the vehicle may be configured to generate the trigger signal when the vehicle has determined the verified reference fire condition. The generation may also depend on and / or based on whether the vehicle is at the destination and / or at the extinguishing agent deployment location. By generating the trigger signal, the time and / or the amount of discharged, in particular sprayed and / or ejected extinguishing agent can be controlled. This is particularly useful if the amount of extinguishing agent is limited. Because in this case the triggering be controlled unit by means of the vehicle so that the most effective extinguishing a fire takes place.

A further advantageous embodiment of the vehicle is characterized in that the vehicle is designed and / or configured, a signal representing a triggering time at which the trip unit releases the extinguishing agent flow, and / or a triggering duration of the released extinguishing agent flow to a central processing unit transferred to. For this purpose, the signal connection, in particular radio signal connection, can be used between the vehicle and the central unit. Corresponding, previous explanations, preferred features, advantages and / or effects are referred to in an analogous manner. By notifying the triggering time and / or the triggering duration of the central processing unit, the central processing unit can document, in particular, the triggering time and / or the triggering duration.

A further advantageous embodiment of the vehicle is characterized in that the vehicle is designed to release the extinguishing agent for a predetermined extinguishing period, in particular by controlling the tripping unit. The predetermined extinguishing time period can be chosen and / or determined such that multiple extinguishing agents can be released by the fire extinguishing unit. In other words, it can be prevented by the predetermined deletion period that the entire extinguishing agent, which is available to the fire-extinguishing unit, is released in an uninterrupted process. Rather, it may be provided that the vehicle is designed and / or configured to release the extinguishing agent in several time periods. Each period can correspond to the predetermined deletion period.

A further advantageous refinement of the vehicle is characterized in that the vehicle is designed to re-detect a fire parameter by means of the vehicle sensor unit after the triggering time, during the release of the extinguishing agent flow and / or after the extinguishing time has elapsed, and the vehicle based on the re-detected fire parameter is designed to determine an extinguishing state when the re-detected fire characteristic represents an extinguished fire. An erase state is therefore present when a fire or smoldering fire is completely extinguished. An erase state may also be present if one corresponding to a fire precursor Reaction is completely interrupted and also automatically stops. For example, by generating a triggering signal, the vehicle may release extinguishing agent to the nozzle to extinguish a fire in the fire alarm monitoring area. The release of the extinguishing agent can take place for the predetermined extinguishing period. After expiration of the deletion period, the vehicle can then again detect the fire parameter by means of the vehicle sensor unit. This newly recorded fire characteristic therefore provides information as to whether the fire in the fire detector monitoring area has already been extinguished by the extinguishing agent or not. For example, if the re-detected fire parameter represents a temperature that corresponds to an extinguished fire, the vehicle may determine the extinguishing condition based on the re-detected fire parameter. However, if the re-detected fire parameter still corresponds to a fire, a fire precursor and / or a smoldering fire, then the extinguishing state is not determined by the vehicle. Preferably, the vehicle is designed and / or configured such that the renewed detection of the fire parameter occurs before a lapse of a predetermined period of time following the triggering time or after the extinguishing period has expired. Thus, it can be ensured that the re-detection of the fire characteristic takes place after the extinguishing agent has been applied. For example, should a fire with the application of the extinguishing agent not be deleted, so the predetermined period of time can serve to limit so that a stronger development of the combustion process is prevented until re-detection of the fire characteristic.

A further advantageous embodiment of the vehicle is characterized in that the vehicle is designed to re-generate the trigger signal, so that the trip unit again releases an extinguishing agent flow to the nozzle and / or the output port when the re-detected fire characteristics a fire, a fire precursor and / or represents a smoldering fire. Thus, if it is determined by means of the vehicle with the re-detected fire parameter that, for example, a fire has not yet been extinguished by the prior discharge of the extinguishing agent, the renewed generation of the trigger signal serves to further extinguish the fire. The same can apply to the fire precursor and / or the smoldering fire.

After extinguishing agent has been applied again, according to the explanation of the penultimate embodiment of the vehicle, a new detection of the fire characteristic to determine an erasure state based thereon, if necessary, if the last re-detected fire parameter represents an extinguished fire. If the erase state is determined, no renewed generation of the trigger signal takes place. If, on the other hand, the extinguishing state is not established, the newly acquired fire parameter thus again represents a fire, a fire precursor and / or a smoldering fire, then the vehicle can again generate a trigger signal to release extinguishing agents to the nozzle and / or the outlet connection. This explained sequence can be repeatedly executed by the vehicle.

A further advantageous embodiment of the vehicle is characterized in that the again generated trigger signal, or a re-generated trigger signal is generated by the vehicle such that the trip unit releases a different extinguishing agent than the previously released extinguishing agent to the nozzle and / or the output terminal , For this purpose, the vehicle may have, for example, at least two extinguishing agent containers, each with different extinguishing agents. Thus, the vehicle may be configured to generate the trigger signal such that first extinguishing agent is released from one of the extinguishing agent container and is released at another generation of the trigger signal extinguishing agent from another extinguishing agent container. Furthermore, the vehicle may preferably be embodied and / or configured such that, during the first generation of the triggering signal, extinguishing agent is released from an extinguishing agent container and, upon renewed generation of the triggering signal, extinguishing agent is released from the input connection and / or the extinguishing agent generating device. Thus, the vehicle may be configured to release extinguishing agents from different sources when the triggering signal is regenerated. This offers the advantage that a fire with different extinguishing agents can be deleted.

An advantageous embodiment of the vehicle is characterized in that the vehicle is configured and / or configured to determine an alarm signal based on the verified reference fire condition. As explained above, the verified reference firing state is determined only in the event that the reference firing state and the verification firing state at least sufficiently coincide, so that it can reliably be used, for example, for a fire in the fire alarm monitoring system. area can be closed. The alarm signal can therefore serve to initiate a follow-up reaction, in particular if necessary. A follow-up action may, for example, be a shutdown of a device in the fire detector monitoring area and / or in the immediate vicinity of the fire detector monitoring area. Alternatively or additionally, the alarm signal can be used to inform a further unit, in particular the central unit, of the verified reference fire condition. Thus, the vehicle may be configured to send the alarm signal to the further unit, in particular central unit. The explanation of a corresponding signal connection is made in an analogous manner. The further unit may be, for example, an extinguishing control center and / or a control center. Furthermore, it can preferably be provided that the alarm signal or a signal based on the alarm signal, acoustically and / or optically, is output from the vehicle. For this purpose, at least one corresponding output unit can be provided for the vehicle. The alarm signal therefore offers the advantage that a corresponding alarm, which indicates a fire, a fire precursor and / or a smoldering fire in the fire alarm monitoring area, can be emitted acoustically and / or optically. Thus, persons in the fire alarm monitoring area can be informed immediately about the corresponding danger situation.

A further advantageous embodiment of the vehicle is characterized in that the vehicle is configured and / or configured to determine a false alarm signal that represents an erroneous determination of the reference fire condition and / or a non-verified reference fire condition in the event that the reference fire condition is not was determined as a verified reference fire condition. The reference firing state is preferably not determined as a verified reference firing state if the reference firing state and the verification firing state do not match and / or do not sufficiently match. This may be the case, for example, if the reference firing state corresponds to a fire, whereas the verification firing state does not correspond to a fire, a smoldering fire or to a potentially non-relevant fire precursor. The Verifikationsbrandzustand indicates in this case that in the fire alarm monitoring area no fire, no smoldering fire or no relevant fire precursor prevails. This suggests that the reference fire condition can be determined incorrectly. A verification of the reference fire condition should therefore not be made. In this case, the vehicle can determine the false alarm signal. The false alarm signal therefore provides the information that the reference fire condition has been erroneously determined or that the reference fire condition could not be verified. Thus, it can be assumed that the fire detector has erroneously determined a fire, a fire precursor and / or a smoldering fire, although there is no actual fire, no relevant fire precursor and / or no relevant smoldering fire in the fire alarm monitoring area. The false alarm signal may be output acoustically and / or optically from the vehicle. For this purpose, at least one corresponding output unit can be provided for the vehicle. Alternatively or additionally, the false alarm signal can be used to inform another unit, in particular the central unit, about the non-verified reference fire condition. Thus, the vehicle may be configured to send the false alarm signal to the further unit, in particular the central unit. A corresponding signal connection between the vehicle and the further unit, in particular the central unit, is referred to in an analogous manner. A person monitoring, for example, the central unit is thus informed that an erroneous determination of the reference fire condition may have occurred here. In this case, no shutdown of devices would be initiated in and / or in close proximity to the fire alarm monitoring area. Upon an acoustic and / or visual output of the false alarm signal, and / or a signal based thereon, persons in the fire alarm monitoring area can be informed of the false alarm signal or the erroneous determination of the reference fire state. This can have a calming effect on people who are in the fire alarm monitoring area.

A further advantageous refinement of the vehicle is characterized in that the vehicle is designed and / or configured to determine a guard signal based on the extinguished state. As previously explained, the erase state is determined in the event that the redrawn fire characteristic represents a deleted fire. The guard signal may be used to inform another unit, in particular the central unit, of the extinguished fire. Thus, the vehicle may be designed to transmit the guard signal to the further unit, in particular the central unit, to send. The further unit can be, for example, the fire alarm control panel, the extinguishing control center and / or the control center. The explanation of a corresponding signal connection is made in an analogous manner. Furthermore, it may be provided that the vehicle is designed and / or configured to output the Entwamsignal, or based on the Entwamsignal signal acoustically and / or visually. For this purpose, the vehicle may have a corresponding output unit. This offers the advantage that persons in the fire alarm monitoring area can be informed about the corresponding all-clear for the fire process, which can contribute to reassuring the corresponding persons.

A further advantageous embodiment of the vehicle is characterized in that the vehicle is designed to send the alarm signal, the false alarm signal and / or the Entwamsignal to a central processing unit, in particular a fire alarm panel and / or a control center. The preceding explanations, advantages and / or effects are referred to in an analogous manner.

The unmanned vehicle is also referred to as a delete robot.

This ensures an effective, fast and / or safe extinguishing of the fire with an optimized amount of extinguishing agent. Thus, the fire can be extinguished in this case with the least possible extinguishing agent and at the same time in a particularly short time, since it is ensured that the auszubringende, in particular auszusprühende and / or ejected, extinguishing agent targeted the actual fire, especially the associated fire.

In a preferred embodiment, the extinguishing robot has a fire extinguishing unit for extinguishing a fire, wherein the vehicle is designed to carry out a fire extinguishing action using the fire extinguishing unit.

In a further preferred embodiment, the fire-extinguishing unit of the extinguishing robot comprises an externally accessible output connection for the provision of extinguishing agent, which can be coupled to a counterpart connection of a stationary extinguishing device in order to provide extinguishing means for the stationary extinguishing device.

In a further embodiment, the fire-extinguishing unit has a, in particular detachable, extinguishing agent container in which extinguishing agent is stored or alternatively has two, in particular, detachable extinguishing agent container with different extinguishing agents, for example an extinguishing agent container with synthetic extinguishing agent FK-5-1-12 (C ₄ F ₉ OCH ₃ ) and the other extinguishing agent container with water, which is preferably applied as water mist. This has the advantage that cost-effective the required extinguishing agent can be used in optimized for the extinguishing success amount.

In a further refinement of the erasure robot, the latter has a navigation control unit and is designed and / or configured for controlled navigation to an extinguishing agent container depot, preferably using navigation data. The navigation to the extinguishing agent container depot can preferably also be effected by means of a position signal of the extinguishing agent container depot, which is provided by a transmitting device of the extinguishing agent container depot, preferably in case of fire. The transmission of the position signal is preferably triggered by a central unit, preferably a fire alarm panel. In the extinguishing agent container depot, which is preferably arranged in the fire section, at least one extinguishant container which can be coupled by a coupling device is provided. This has the advantage that the extinguishing robot takes up the extinguishing agent container only when needed, which is energy-saving for the movement of the extinguishing robot. Furthermore, if necessary, the emptied extinguishing agent container can then be exchanged for an extinguishing agent container filled with extinguishing agent for further extinguishing operations.

In a further refinement of the extinguishing robot, it is designed and / or configured for detecting a fire parameter by means of a vehicle sensor unit. If the detected fire parameter represents a fire, a fire precursor and / or a smoldering fire, the extinguishing robot initiates a fire-extinguishing action by means of the fire-extinguishing unit, preferably for a predetermined extinguishing period. Furthermore, the extinguishing robot is preferably designed and / or configured to recapture a fire parameter by means of the vehicle sensor unit after the predetermined extinguishing period and to re-emit extinguishing agent if the newly acquired fire parameter represents a fire, a fire precursor and / or a smoldering fire. Thus, a redress is possible if the first fire extinguishing action has not led to the complete deletion, or the fire has broken out again after the deletion.

In a further refinement of the erasure robot, the latter, in particular the robot control unit, is designed and / or configured again or iteratively to determine the optimized extinguishing agent application position, based on the extinguishing agent application data, in particular based on the throw distance and / or the recalculated fire location Basis of the re-detected fire characteristic was calculated by means of the vehicle sensor unit. This has the advantage that, adapted to the extinguishing progress or the change in the position of the flame front or the position of hotspots, the respectively optimized extinguishing agent application position for rapid extinction can be assumed with a minimum amount of extinguishing agent.

In a further embodiment, the extinguishing robot, in particular the fire-extinguishing unit, has a first, rotationally, pivotally and / or length-adjustable alignment device to which the nozzle is fastened, wherein the extinguishing robot, in particular the computer unit, is designed to control the first alignment device to align the nozzle. Further, the erase robot is preferably configured and / or configured to calculate the orientation of the nozzle based on the previously determined fire location, the extinguishing agent application data, and / or the optimized extinguishing agent application position.

According to a second aspect of the invention, the object mentioned is achieved by a system. The system is used for fire extinguishing. The system has a central unit, in particular a fire alarm panel, and / or a stationary fire detector and a vehicle. The vehicle is a vehicle according to the first aspect of the invention and / or according to one of the explained, advantageous Embodiments of the vehicle. The vehicle has a first signal communication unit that includes the vehicle communication unit of the vehicle. The central unit has a second signal communication unit configured to establish a wireless signal connection with the first signal communication unit of the vehicle. The central unit and / or the stationary fire detector is designed and / or configured to transmit the instruction signal to the vehicle. With respect to the vehicle of the system, reference is made to the foregoing explanations, preferred embodiments, preferred features, advantages and / or effects in an analogous manner as discussed for the vehicle according to the first aspect of the invention and the associated embodiments. With regard to the central unit, reference is also made to the preceding explanations, preferred embodiments, preferred features, advantages and / or effects in an analogous manner.

The first signal communication unit of the vehicle has the vehicle communication unit, which is preferably designed and / or configured to receive the instruction signal. The vehicle communication unit may be configured as a radio signal receiving unit. The first signal communication unit may therefore be at least partially designed as a radio signal communication unit. Thus, the information provided by the instruction signal can be provided to the vehicle. The vehicle communication unit of the vehicle may also have the previously described for the vehicle as advantageous signal transmission unit, which is preferably designed as a radio signal transmission unit. Corresponding explanations, preferred features, effects and / or advantages are referred to in an analogous manner.

The second signal communication unit of the central unit can be designed to send out the instruction signal. For this purpose, the second signal communication unit of the central unit may have a signal transmission unit. The signal transmission unit can be designed as a radio signal transmission unit. The signal transmission unit may also be configured and / or configured to transmit the instruction signal. Thus, the instruction signal wirelessly, so preferably by radio, are transmitted from the central unit to the vehicle. The first signal communication unit and / or the signal communication unit may also be designed for bidirectional transmission of a signal. Thus, each of the two signal communication units may include a signal receiving unit and a signal transmitting unit. This offers the advantage that the vehicle and the central unit can exchange signals, preferably to exchange information representing the respective signals.

An advantageous embodiment of the system is characterized in that the central unit is formed by a fire alarm panel. The fire alarm panel can be designed as a device. Furthermore, it can be provided that the fire alarm panel is designed as a common unit and / or device with a delete control center. Alternatively or additionally, the central unit may have the fire alarm panel and the extinguishing control center. The design of the central unit of at least one fire alarm panel offers the advantage that the central unit can be integrated as a fire alarm panel in an existing system, in particular fire alarm system, and / or an existing system, in particular fire alarm system.

A further advantageous embodiment of the system is characterized in that the central unit is designed for transmitting navigation control signals from the central unit to the vehicle, the vehicle is designed and / or configured to navigate based on the transmitted navigation control signals, and the central unit by Transmission of navigation control signals to the vehicle for remote navigation of the vehicle is formed. As previously explained, the first signal communication unit of the vehicle may include a signal receiving unit and a signal transmitting unit. In addition, the vehicle may be configured and / or configured to receive a location signal. The locating signal may be, for example, a satellite locating signal, such as a GPS signal. Based on the locating signal, the vehicle can be designed and / or configured for autonomous navigation. However, it may happen that obstacles, such as temporary obstacles and / or stationary obstacles, are located on the way to the destination. This information can be available to the central unit. The central unit can therefore transmit navigation control signals to the vehicle to start the vehicle based on the Navigate navigation control signals remotely controlled, or at least to influence the navigation with remote control. Thus, the navigation control signals may serve to bypass and / or fly around said obstacles. The vehicle may therefore be designed to navigate to the destination based on the navigation control signals and the likewise receivable location signals. In addition, provision may be made for the vehicle to send a position signal, which represents the current position of the vehicle, to the central unit by means of the signal transmission unit of the first signal communication unit. This position signal can be received by means of the signal receiving unit of the second signal communication unit of the central unit. Based thereon, the central processing unit may be configured and / or configured to adjust and / or determine the navigation control signal to then send that navigation control signal to the vehicle. In this case, the determination of the navigation control signal can be taken into account using known obstacles on the way to the destination. This embodiment of the system therefore offers the advantage that the vehicle can navigate particularly quickly and / or safely to the destination, since the vehicle does not collide with possible obstacles, but can drive around and / or fly around them.

An advantageous embodiment of the system is characterized by a stationary extinguishing device with a mating connection, which is designed for coupling the output terminal of the vehicle. If the output connection is coupled to the mating connection, a fluid-conducting connection is created between the output connection and the mating connection. By coupling so a fluid-conducting connection is made. The stationary extinguishing device may be designed to dispense extinguishing agent in the fire detector monitoring area, in particular to eject and / or spray it. The stationary extinguishing device is also referred to as extinguishing system. When extinguishing agent is conveyed from the exit port of the vehicle to the counter port of the extinguishing device, the extinguishing device may forward the extinguishing agent to be deployed in the fire detector monitoring area to extinguish therefrom a fire, a precursor fire and / or a smoldering fire. For the extinguishing device of the system, reference is made to the preceding explanations, preferred features, effects and / or advantages in an analogous manner as for the extinguishing device in the context of the discussion of the vehicle according to the first aspect of the invention, or the associated embodiments, was discussed.

A further advantageous embodiment of the system is characterized in that the central unit is designed and / or configured to navigate the vehicle remotely to the destination, the extinguishing agent application, the extinguishing device and / or the extinguishing agent source. For example, the vehicle may be configured to first navigate to the extinguishing agent source based on the received navigation control signals and preferably based on received locating signals in order to couple to the extinguishing agent container, preferably by means of the coupling device, in which the extinguishing agent is stored. The vehicle may then navigate to the destination based on the navigation control signals and / or the location signals to determine whether there is actually a fire. If so, the vehicle may then navigate to the extinguishing agent application location based on received navigation control signals and / or received location signals to then deploy, preferably spray and / or expel the extinguishing agent from the extinguishing agent container. If the extinguishing agent is not to be discharged directly from the vehicle, the vehicle may be designed and / or configured to navigate to the extinguishing device based on the received navigation signals and / or on received location signals. Here, the vehicle may couple the output terminal of the vehicle to the mating terminal of the extinguishing device to convey the extinguishing agent to the extinguishing device. As a result, the extinguishing agent is applied to the fire alarm monitoring area in order to extinguish any fire that may be present, any fire precursor present and / or a smoldering fire which may be present.

An advantageous embodiment of the system is characterized in that the extinguishing device has the mating connection, at least one extinguishing nozzle and a pipeline network which extends between the mating connection of the extinguishing device and the at least one extinguishing nozzle of the extinguishing device. For this purpose, the pipeline network can have at least one extinguishing medium line, but preferably a plurality of extinguishing medium lines coupled to one another. If the extinguishing device has, for example, a plurality of extinguishing nozzles, then the pipeline network can be replaced by means of the Extinguishing medium lines may be formed to direct extinguishing agent from the counter-connection to the extinguishing nozzles. The preceding explanations, preferred features, effects and / or advantages, as have been explained in connection with the vehicle according to the first aspect, and the associated embodiments, is referred to in an analogous manner.

An advantageous embodiment of the system is characterized in that the extinguishing device is designed to extinguish a fire in the fire alarm monitoring area by extinguishing agent from the output terminal of the vehicle to the counter-connection of the extinguishing device and through the pipe network to the at least one extinguishing nozzle of the extinguishing device can be conveyed. If extinguishing agent is now conveyed from the outlet connection to the counterpart connection, the pipeline network directs the extinguishing agent to the extinguishing nozzles, which then discharge the extinguishing agent in order, for example, to extinguish a fire in the fire detector monitoring area. The preceding explanations, preferred features, effects and / or advantages, as have been explained in connection with the vehicle according to the first aspect, and the associated embodiments, is referred to in an analogous manner.

A further advantageous embodiment of the system is characterized by a stationary fire detector, wherein the fire detector has a fire detector sensor unit which is designed to detect a reference fire characteristic of a predetermined fire alarm monitoring area, the fire detector being designed to determine a reference fire condition by evaluating the reference fire parameter, wherein the fire detector is adapted to transmit a fire alarm signal representative of the reference fire condition to the central processing unit, the central processing unit being configured to issue an instruction signal to the vehicle in the event that the fire alarm signal transmitted by the fire detector represents a reference fire condition requiring verification wherein the instruction signal represents at least one destination for the vehicle, and wherein the vehicle monitoring area is in sufficient overlap with the fire detector is monitoring range when the vehicle is at the target location.

The system is for fire extinguishment, preferably based on the verified reference fire condition. The system has the central unit, the at least a stationary fire detector and the unmanned vehicle. The stationary fire detector is also called a fire detector. The system offers the advantage that a reference fire state determined by a fire detector can be checked by means of a verification fire state determined by the vehicle, provided that the stated states at least sufficiently coincide, a verified reference fire state can be determined. Thus, the system allows a determination of a verified fire condition, namely the verified reference fire condition. A transmission of sensor data from the vehicle to the central unit can therefore be dispensed with. A signal connection between the vehicle and the central unit, which is preferably designed as a radio link, therefore does not have to be suitable for being able to transmit large amounts of data in a short time. Rather, the verified reference fire condition can be determined by means of the vehicle at the destination location, or the vehicle transmits a verification signal representing the verification fire condition to the central unit, so that the central unit can optionally determine the verified reference fire condition.

Another advantage of the system is the automatic determination of the verified reference fire state as such. For the Verificationsbrandzustand can be determined by the vehicle itself, so that based on an automatic review of the reference fire condition can take place, so that the verified reference fire condition is automatically determined at a sufficient match. This can be done without human intervention, so that the determination of the verified reference fire condition can be done very quickly and safely.

In addition, the system is inexpensive and at the same time very flexible and / or versatile. Because the vehicle can navigate to any destination, in particular drive and / or fly. Thus, the vehicle of the system may be used to acquire a verification fire characteristic of a fire detection area of any fire detector. Because the vehicle is mobile and therefore not tied stationary or assigned to a stationary device. It is therefore no longer necessary to provide for each fire alarm or for a group of fire detectors in a surveillance area an additional surveillance system, such as a stationary installed camera system, to provide one of the respective fire detector to verify or verify specific reference fire condition. Due to the low cost of only one vehicle and due to the mobility of the vehicle, the system is particularly cost effective and flexible.

The verified reference firing condition may serve as a reliable basis for initiating a follow-up action such as a fire-extinguishing action to initiate a fire extinguishment in the fire alarm monitoring area, for example. The system can form at least part of a fire detection system. A fire alarm system is preferably also referred to as a fire alarm system. The system or the fire alarm system can therefore also serve for preventive fire protection.

Fire detectors are basically known from the prior art. For the system it is envisaged that at least one fire alarm is installed stationary. Such a fire detector can be permanently installed, for example, in a building, on a building or on an object to be protected or in its vicinity. The stationary fire detector is also referred to as fire alarm. The fire detector may be formed, for example, as a fire gas detector, a smoke detector, a heat detector, a flame detector, a detector for detecting electromagnetic radiation from a predetermined spectrum, which preferably indicates a fire, or a combination of the aforementioned detectors.

The fire detector has a fire detector sensor unit. Preferably, the fire detector sensor unit is formed by a sensor or a sensor unit. The fire detector sensor unit is also designed to detect a fire characteristic of a fire alarm monitoring area. The fire parameter detected by the fire detector sensor unit is referred to as the reference fire parameter. A fire parameter can basically represent and / or characterize at least one physical and / or chemical property of a combustion process. For a preferred embodiment, it can be provided that the fire detector sensor unit is designed in the manner of a multi-sensor unit or with a plurality of, in particular, different sensors. The sensor signals and / or sensor data of the multi-sensor or the plurality of sensors can be generated by means of a preprocessing unit, in particular based on stored signal patterns or data are evaluated in order to determine the resulting fire characteristic. For this purpose, the fire detector sensor unit can be designed and / or configured accordingly. The determined fire parameter can then be referred to as the detected fire parameter or reference combustion parameter. If the fire detector is stationary installed, the fire alarm monitoring area is also preferably a stationary fire alarm monitoring area. The fire detector monitoring area is preferably an area assigned to the fire detector, which is preferably to be monitored by the fire detector for a fire, a fire precursor and / or a smoldering fire. Preferably, the fire detector is a so-called automatic fire detector. Because with the fire detector sensor unit, the reference fire characteristic of the fire alarm monitoring area can be automatically detected. The detection can take place continuously or discretely, for example at predetermined time intervals.

Depending on the intended use, the fire detector sensor unit can be designed to detect different reference fire parameters. An example of a reference combustion parameter is, for example, the temperature. In this case, the fire detector sensor unit may be configured to detect the temperature of the fire detector monitoring area. The fire detector sensor unit may be formed in this case as a temperature sensor unit or as a temperature sensor. The same applies to the following possible fire characteristics. Thus, a fire parameter, for example, a smoke concentration, which is also referred to as smoke particle concentration, a concentration of a predetermined gas, a concentration of a plurality of predetermined gases, a concentration of at least one thermal decomposition product or one, in particular average, amplitude of a predetermined electromagnetic spectral range. A fire characteristic may also be a change and / or slope value of at least one of the aforementioned fire characteristics. For example, the fire parameter may be a temperature gradient or a concentration gradient. For detecting a concentration of a gas, the fire detector sensor unit may be designed, for example, as a gas sensor unit or as a gas sensor. If the fire detector sensor unit is used to detect an amplitude of a predetermined electromagnetic spectral range, the fire detector sensor unit can be used as an optical and / or photoelectric sensor unit for detecting a corresponding, in particular average, amplitude of the be formed predetermined electromagnetic spectral range. This spectral range can originate, for example, from the ultraviolet, infrared and / or near-infrared regions.

The recorded reference combustion parameter thus provides information as to whether a fire, a fire precursor or a smoldering fire prevails in the fire alarm monitoring area.

Based on the detected reference combustion parameter, preferably based on the at least one detected reference combustion parameter, the fire detector is designed to determine a reference fire condition. For this purpose, the reference combustion parameter is evaluated by the fire detector. For evaluation, the fire detector may have an evaluation unit. The evaluation unit may be designed in the manner of a data processing unit for evaluating the reference fire characteristic. If, for example, the temperature of the fire alarm monitoring area is detected by the fire detector sensor unit, the reference fire state can be determined by evaluating the temperature by means of the fire detector. For example, if the temperature exceeds a predetermined threshold, it may be determined as a fire for the reference firing condition. In particular, in the case of a smoldering fire or during a combustion process without a light phenomenon, it can be concluded, for example by detecting the concentration of a predetermined gas, that a fire precursor or a smoldering fire is to be determined as the reference combustion state. If a reference combustion parameter is detected by the fire detector sensor unit, which does not correspond to any fire and also does not correspond to a fire precursor or a smoldering fire, then no reference fire condition is determined. The fire detector can be designed and / or configured accordingly.

For a preferred embodiment, it can be provided that the fire detector sensor unit is designed in the manner of a multi-sensor unit or with a plurality of, in particular, different sensors. The sensors or the multi-sensor unit can be designed to determine a plurality of fire characteristics, these fire characteristics being referred to as reference fire parameters. Based on the aforementioned reference combustion parameters recorded, the fire detector can be designed to determine a reference fire condition. These are the Reference combustion parameters evaluated by the fire detector. For evaluation, the fire detector may have an evaluation unit. The evaluation unit may be designed in the manner of a data processing unit for evaluating the reference fire parameters. In the evaluation, in particular neural networks can be used.

When a reference fire condition has been determined by the fire detector, the fire detector may transmit a fire alarm signal representing the reference fire condition to the central unit. For this purpose, the fire detector may have a signal transmission unit. The central unit may have a signal receiving unit for this purpose. Thus, the fire alarm signal can be transmitted by means of the transmitting unit of the fire alarm to the signal receiving unit of the central unit, so that the central unit of the fire alarm signal or the reference fire condition is provided. In this case, the transmission unit can be designed as a radio transmission unit and the signal reception unit as a radio signal reception unit. Alternatively or additionally, a line-connected signal connection can be formed between the signal transmission unit and the signal reception unit. In other words, the central unit and the fire detector can be connected to each other by means of a wired signal connection and / or by means of a radio link in order to enable the transmission of the fire alarm signal. If a wired signal connection is used to transmit the fire alarm signal, the fire alarm signal can be represented and / or modeled by a current signal and / or voltage signal. For this purpose, for example, the current intensity and / or the voltage potential of the fire detector can be adapted to transmit the fire alarm signal. The wired signal connection can lead from the central unit to a plurality of fire detectors, wherein the fire detectors are connected in series by means of the wired signal connection. In this case we also talk about a fire detection line. The wired signal connection can also be designed as a bus line. In this case, each of the plurality of fire detectors each forms a bus subscriber. Each bus user can have his own address, which is also called the bus address. Overall, therefore, a bus system for the transmission of information can be formed by the bus users and the bus line. Preferably, the bus system is designed as a ring bus system. The information is or relates to, for example, the fire alarm signal. So a fire detector can fire the fire alarm signal send to the central unit by means of the bus or bus system. This can be done, for example, in bit-serial form and in the half-duplex method. The fire alarm signal or the associated data information from the fire detector is modulated onto a bus supply voltage provided by the central unit. The central unit demodulates the corresponding signals so that the fire alarm signal is available to the central unit.

For an advantageous embodiment, it may be provided that the fire detector or at least one of the fire detectors, preferably each of the fire detectors, is supplied by the central unit with electrical energy. This can be done by means of the aforementioned, wired signal connection. This can in fact also serve for the transmission of electrical power from the central unit to the respective fire detector and / or be designed. For example, the central unit can provide a DC voltage, wherein signals are modulated by means of an AC voltage.

The central processing unit is configured and / or configured to transmit an instruction signal to the vehicle. Thus, the central processing unit is preferably designed to send the instruction signal to the vehicle.

The second signal communication unit of the central unit and the first signal communication unit of the vehicle serve to transmit the instruction signal. Thus, the instruction signal can be sent to the vehicle by means of a signal transmission unit of the second signal communication unit. The signal receiving unit of the first signal communication unit of the vehicle may be configured and / or configured to receive the instruction signal. Thus, the central unit and the vehicle may preferably be interconnected by means of a radio signal connection in order to transmit the instruction signal from the central unit to the vehicle. However, the instruction signal is only transmitted to the vehicle in the event the fire detector signal transmitted by the fire alarm represents a reference fire condition requiring verification. The reference fire condition preferably requires verification when the reference fire condition represents a fire. For example, if the stationary fire detector is installed in a factory building where it is installed Due to a production of components regularly comes to a smoke, so it may happen that the fire detector is a corresponding to a fire precursor reference fire condition is determined. In this case it can be provided that a corresponding reference fire condition requires no verification. However, the illustrated example is but one of many examples of when a reference fire condition requires verification. Thus, it may be provided that the reference firing state preferably requires verification if this corresponds to a fire, a precursor fire or a smoldering fire. If the reference firing condition now requires verification, the instruction signal is transmitted from the central unit to the vehicle.

The instruction signal represents at least one destination for the vehicle. The destination may be a location coordinate, have a location coordinate, represent a limited space, and / or represent an area. In addition, the destination may also have further location information, such as orientation information for the vehicle and / or for the vehicle sensor unit of the vehicle. The foregoing explanations, preferred features, effects, and / or advantages discussed in connection with the instruction signal and / or the navigation of the vehicle according to the first aspect of the invention, and / or the associated embodiments, will be made in an analogous manner taken.

If a navigation, ie preferably a guided movement, of the vehicle to the destination takes place, then the vehicle monitoring area and the fire alarm monitoring area are sufficiently overlapping. For at the destination, the vehicle is preferably at a predetermined distance to the fire alarm monitoring area or even in the fire alarm monitoring area. Since the vehicle monitoring area moves along with the navigation of the vehicle, the sufficient overlap of the vehicle monitoring area with the fire detector monitoring area takes place when the vehicle is at the destination.

Preferably, it is provided that the vehicle monitoring area and the fire alarm monitoring area then sufficiently overlap if at least 30%, at least 40%, at least 50%>, at least 60%>, at least 70%>, at least 80%>, at least 90% or 100% of the vehicle surveillance area is in overlap with the fire alarm monitoring area. In the area in which the vehicle monitoring area and the fire detector monitoring area overlap, a corresponding reference fire state as well as a corresponding verification fire state can be determined both by the fire detector and by the vehicle.

If the reference combustion state and the verification fire state at least sufficiently agree, the verified reference fire state is determined by the vehicle. The verified reference firing state can correspond to a fire, a precursor fire or a smoldering fire or represent the fire, the fire precursor and / or the smoldering fire. The verified reference fire condition therefore provides reliable information as to whether a fire, a precursor fire or a smoldering fire actually prevails in the fire alarm monitoring area.

In addition, the vehicle is configured and / or configured to initiate a fire-extinguishing action if the reference fire condition has been determined to be a verified reference fire condition. Corresponding explanations, advantageous features, preferred embodiments, effects and / or advantages, as have been explained in connection with the vehicle according to the first aspect, and / or the associated embodiment variants, reference is made in an analogous manner.

An advantageous embodiment of the system is characterized in that a measuring principle of the fire detector sensor unit and a measuring principle of the vehicle sensor unit are different. If the system has several fire detectors, the measuring principle of each fire detector can be the same. In one example, the type of sensor used for a vehicle sensor unit may be different than a type of sensor for the at least one fire sensor unit. By using different measuring principles for the vehicle sensor unit and the at least one fire detector sensor unit, measurement principle-related incorrect measurements and corresponding errors in the determination, in particular of the verified reference fire condition, can be prevented or at least reduced. An advantageous embodiment of the system is characterized in that the system has a plurality of stationary fire detectors. Each of the fire detectors can be designed in an analogous manner to the already described fire detector. In this context, for each of the fire detectors in an analogous manner to the explanations to the already discussed fire detector as well as the resulting advantages and / or effects reference. In addition, the central unit may be configured and / or configured to receive a fire alarm signal emitted by each fire detector. If the system has several stationary fire detectors, it can monitor larger areas and / or larger buildings, for example. The fire detectors can be arranged such that their fire alarm monitoring areas directly adjoin one another and / or at least partially overlap.

A further advantageous embodiment of the system is characterized in that the central unit is designed to determine a fire alarm location of the fire detector, which has transmitted the fire alarm signal based on a transmitted fire alarm signal of a fire detector, and that the central unit is formed, the destination based on to determine the fire alarm location. The fire alarm signal transmitted by the fire detector can also have an identifier. The identifier may also be referred to as an address, bus address or address identifier, in particular a fire detector. The identifier can provide information about the fire alarm location. The central unit may be configured to determine the fire detector location based on the identifier. Alternatively or additionally, data may be stored by the central unit, which represent each of a plurality of identifiers, which are transferable from the fire detectors by means of the fire alarm signal to the central unit, a corresponding fire detector location. If an identifier from the fire detector is now also transmitted to the central unit by means of the fire alarm signal, then the central unit can be designed based on the fire alarm signal for determining the fire alarm location of the fire detector using the aforementioned data. In addition, data may be stored by the central unit representing an associated destination for each fire alarm location. In particular, based on these data, the central processing unit may therefore be configured and / or configured to determine an associated destination based on the determined fire alarm location, which then is used to transmit an instruction signal to the vehicle so that it can navigate to the appropriate destination.

The data previously designated by the central unit for determining the destination and / or the fire alarm location may alternatively be stored by another unit and / or another system, wherein the central unit has a communication connection to the corresponding unit or system, and wherein the central unit is designed to query the corresponding data in the said unit or said system, in order to then carry out the corresponding determination of the destination or fire alarm location.

A further advantageous embodiment of the system is characterized in that the central unit is configured to determine the instruction signal such that the instruction signal represents at least one destination for the vehicle, in which the vehicle monitoring area, when the vehicle is at the destination, in sufficient overlap with the fire alarm monitoring area is whose reference fire characteristic was detected by the fire detector sensor unit of the fire detector, which has transmitted the fire alarm signal to the central unit. If, for example, a reference fire parameter is detected by one of the fire detectors and a fire alarm signal is then transmitted to the central unit, the central unit determines the instruction signal in such a way that the destination of the vehicle represented by the instruction signal is selected such that the vehicle monitoring area is sufficiently overlapped with the fire alarm monitoring area is when the vehicle is at the destination. Thus, the central processing unit is configured to determine a corresponding destination or instruction signal for each of the fire detectors so that when the vehicle receives this instruction signal, it can navigate to the corresponding destination to overlap the vehicle monitoring area with the corresponding fire detector monitoring area to reach. This embodiment of the system offers the advantage that a plurality of stationary fire detectors can be provided, and that the vehicle can navigate to a respectively adapted destination by means of the instruction signal in order to achieve the overlap between the vehicle monitoring area and the fire detector monitoring area associated with the fire detector. Thus can on a Majority of vehicles are dispensed with. Rather, only one vehicle is sufficient for a determination of a verified reference fire condition, even with a plurality of fire detectors. Therefore, the system can be designed particularly cost-effective even with a variety of fire detectors and still provide the opportunity to check a reference fire condition and possibly to determine a verified reference fire condition.

In Fig. 1, an unmanned vehicle 2 is shown schematically. The unmanned vehicle 2 is also referred to as vehicle 2. The unmanned vehicle 2 is used for fire extinction. In addition, in Fig. 1, a system 20 is shown, which also serves to extinguish fire. The system 20 comprises a stationary fire detector 14, a central unit 22, designed here as a fire alarm control panel 138, and the unmanned vehicle 2.

In order to avoid repetition, the unmanned vehicle 2 should be explained in connection with the system 20. While discussing relationships between the unmanned vehicle and other parts of the system 20, it is contemplated that corresponding features discussed for the unmanned vehicle 2, advantageous features, effects, and / or benefits may also be provided separately for the unmanned vehicle 2 in analog Way to apply. It should therefore be noted at this point that the below explained advantageous embodiments, preferred features, effects and / or benefits in a similar manner for the unmanned vehicle 2, even in the case when this is not part of the system 20th forms, should apply in an analogous manner.

The stationary fire detector 14 shown schematically in FIG. 1 can be installed, for example, in a building 30. The stationary fire detector 14 is also referred to as a fire detector 14. The fire detector 14 may for example be attached to a ceiling 32 of a room 34 of the building 30. The fire detector 14 may be designed for this purpose, for example, as a fire gas detector, a smoke detector or as a flame detector. Further embodiments of the fire detector 14 are known from the prior art and also form possible embodiments for the fire detector 14. By the fire detector 14 is fixedly attached to the ceiling 32 of the building 30, the fire detector 14 is immovable and thus formed as a stationary fire detector 14.

From the fire detector 14 is a part of the room 34, namely the fire detector monitoring area 12, monitored. The fire detector monitoring area 12 can thus be assigned to the fire detector 14. The fire detector 14 is used to detect a fire, a fire precursor and / or a smoldering fire. To make this possible, the fire detector 14 a sensor unit, which is referred to as fire detector sensor unit 28. The fire detector sensor unit 28 is designed to detect a reference fire parameter K _{R of} the fire detector monitoring area 12. If the fire detector 14 is designed, for example, as a fire gas detector, the associated fire detector sensor unit 28 can be designed to detect a smoke concentration and / or to detect a concentration of at least one predetermined gas. The predetermined gas may be a gas, in particular CO ₂ and / or CO, which is formed during combustion. The smoke concentration or the concentration of the predetermined gas in this case forms the reference parameter K _R , which can be detected by the fire detector sensor unit 28. In principle, a detection can be a direct or indirect detection.

In addition, the fire detector 14 is designed to determine a reference fire state Z _R by evaluating the reference fire characteristic K _R. For this purpose, the fire detector 14 may have an evaluation unit. The evaluation unit is preferably designed to evaluate the reference fire characteristic K _R. In addition, the evaluation unit is preferably designed to determine the reference fire state Z _R based on the result of the evaluation. A reference firing state Z _R represents, for example, a fire, a fire precursor and / or a smoldering fire. In the case of a fire, a fire precursor and / or a smoldering fire, characteristic gases, such as CO, which can be measured, for example, by the fire detector sensor unit 28, often arise. FIG. 2 schematically illustrates an exemplary value profile of the reference combustion parameter KR over time t. Of the fire detector 14, and preferably from the associated evaluation unit, at least a threshold Wsi, preferably, be stored a plurality of threshold values Wsi, Ws _2, Ws. ₃ These threshold values Wsi, Ws2, Ws ₃ can be threshold values for the reference combustion parameter KR, ie, preferably for a gas concentration measured by the fire detector sensor unit 28. If a reference combustion parameter K _R detected by the fire detector sensor unit 28, in particular a corresponding smoke concentration, exceeds a first one of the threshold values Wsi, this may be characteristic of a smoldering fire, for example. FIG. 3 schematically illustrates an exemplary state progression of the reference fire state Z _R over the time t and corresponding to the value profile of the reference combustion parameter KR from FIG. 2. If the detected reference combustion parameter K _R reaches and / or exceeds the threshold value Wsi, then based on this a reference fire state ZRI can be determined, which corresponds, for example, to a smoldering fire. If, for example, a higher reference combustion parameter KR, ie in particular a higher smoke concentration, is detected, the reference combustion parameter K _R or the smoke concentration can reach and / or exceed a further one of the threshold values Ws ₂ , so that this may be characteristic for a fire precursor and a corresponding reference fire condition ZR2 can be determined. Reached and / or the detected reference fire parameter K _R exceeds the threshold values other Ws _3, it may based on this, a reference fire condition Z are determined _R3, for example, corresponds to a fire. 4 Thus, it is preferably provided that the evaluation unit of the fire detector 14 is designed based on the detected reference fire characteristic KR, and preferably using at least one threshold value Wsi, Ws ₂ , Ws ₃ , for determining a reference fire state Z _R.

The system 20 also includes a central processing unit 22. The central unit 22 is preferably part of a fire alarm system (not shown), which may also be referred to as a fire alarm system. Alternatively or additionally, the central unit 22 may be a fire alarm panel or at least part of a fire alarm panel. Furthermore, it can be provided that the central unit 22 is at least part of a control center unit (not shown) and forms. Without limiting the general concept of the invention is purely by way of example It can be assumed that the central unit 22 is a fire alarm panel. For the sake of completeness, it should be pointed out that the central unit 22 can be designed as a fire alarm panel at least partially together with an extinguishing control center 64. For a fire alarm panel and a delete control center 64 may for example be at least partially formed as a common unit.

The stationary fire detector 14 is connected to the central unit 22 by means of a signal line connection 36. Thus, there is a signal connection between the stationary fire detector 14 and the central unit 22. In order to transmit a signal from the stationary fire detector 14 to the central unit 22, the stationary fire detector 14 has a signal transmission unit 38. The signal transmission unit 38 of the fire detector 14 is connected to the signal line 36. The central unit 22 has a signal receiving unit 40. The signal receiving unit 40 of the CPU 22 is also connected to the signal line 36. The signal line 36 may therefore extend from the signal transmission unit 38 of the fire detector 14 to the signal reception unit 40 of the central unit 22. Thus, a fire alarm signal S _B can be transmitted from the fire detector 14 to the central unit 22. The fire detector 14 is thus designed to transmit the fire alarm signal S _B , which represents the reference fire state Z _R , to the central unit 22. By means of the transmission of the fire alarm signal S _B from the fire detector 14 to the central unit 22, the central unit 22 of the reference fire condition Z _R or the information about it can be made available.

If a reference fire state Z _R , which corresponds to a fire, was determined by means of the fire detector 14 and a fire detector signal S _B representing the corresponding reference fire state Z _{R was} transmitted to the central unit 22 by the fire detector 14, it was often not clear in the prior art It is clear whether a fire 4, or possibly a fire precursor and / or a smoldering fire, actually prevails in the fire alarm monitoring area 12. Because by deception sizes and / or by unforeseen circumstances, it may happen that the fire detector 14 determines a corresponding to a fire 4 reference fire condition Z _R , although in fact no fire 4 prevails in the fire alarm monitoring area 12. The more often such illusions and / or unforeseen circumstances occur, which lead to the result explained above, the greater the Danger at emergency services to extinguish a fire 4 that a corresponding to an actual fire 4 reference fire condition Z _{R is} not perceived and / or interpreted with the necessary seriousness. However, this entails risks, because only by a direct and timely fire fighting can be effectively prevented in time exponentially increasing property and / or personal injury in the fire alarm monitoring area 12 of the room 34. Therefore, as prompt and early as possible a review and / or verification of the reference fire condition Z _{R is} of great importance. Thus, if a fire alarm signal S _B representing the reference fire condition Z _{R is} transmitted from the fire detector 14 to the central unit 22, in practice, a person is often sent to the fire detector 14 or the fire alarm monitoring area 12 to check whether a the reference fire condition Z _R corresponding fire 4, or fire precursor and / or smoldering fire, actually exists. In the period between the transmission of the fire alarm signal S _B from the fire detector 14 to the central unit 22 and the arrival of the person in the room 34 or at the fire detector monitoring area 12, the combustion process can evolve. Thus, for example, a smoldering fire may have already caused an actual fire 4 with a light effect. Accordingly, the risk of property damage and / or personal injury increases. If the person has arrived to assess the fire alarm monitoring area 12 for a possible fire, or a fire precursor and / or a smoldering fire, the person can provide appropriate feedback, so that the reference fire condition Z _R can or may not be confirmed. Against the background explained above, it is provided according to the invention to propose a system 20 which can as far as possible avoid or at least reduce a possible risk of property damage and / or personal injury.

With the unmanned vehicle 2 according to the invention and / or with the system 20 according to the invention, it should therefore be possible to be able to automatically verify the reference fire state Z _R so that, if appropriate, a verified reference fire state ZV _R results therefrom. In addition, it should be possible with the vehicle 2, if the reference fire condition Z _{R was determined} as a verified reference fire condition ZV _R to initiate a fire extinguishing action. The central unit is therefore configured and / or designed to transmit an instruction signal Si to the vehicle 2. However, the transmission of the instruction signal Si takes place only when the fire alarm signal SB transmitted by the fire detector 14 represents a reference fire state ZR which requires verification. In principle, it can be provided that every reference fire state Z _R requires verification. In this case, the instruction signal Si is transmitted to the vehicle 2 when the CPU 22 receives the fire alarm signal SB from the fire detector 14. However, it may happen that not every reference fire condition ZR requires verification. If the reference combustion state Z _R corresponds, for example, to a combustion precursor, then it may be provided that a corresponding reference combustion state ZR does not require any verification.

The central unit 22 and the vehicle 2 are interconnected by means of a signal connection 42. The signal connection 42 is preferably a radio signal connection. In this case, the central unit 22 has a signal transmission unit 44, which is preferably designed as a radio signal transmission unit. Thus, the instruction signal Si can be sent to the vehicle 2 by means of the signal transmission unit 44. For receiving the instruction signal Si, the vehicle 2 has a vehicle communication unit 10, which is preferably designed as a radio signal receiving unit. In this case, it is not necessary for the instruction signal Si to be transmitted directly from the signal transmission unit 44 of the central unit 22 to the vehicle communication unit 10 of the vehicle 2. Thus, for example, at least one transmitter (not shown) may be provided, which is designed for signal forwarding, and which serves to forward the instruction signal Si from the central unit 22, or the associated signal transmission unit 44, to the signal receiving unit 10 of the vehicle 2.

The vehicle 2 has a sensor unit, which is referred to as a vehicle sensor unit 6. The vehicle sensor unit 6 is designed to detect a fire parameter Kp of a vehicle monitoring area 8. The previous explanations of the reference combustion parameter KR are referred to in an analogous manner for the fire parameter Kp. However, in this case the vehicle sensor unit 6 is used to record the fire parameter K _{F of} the vehicle monitoring area 8. Area 8 can thus be assigned to the vehicle sensor unit 6. In other words, the vehicle monitoring area 8 can be assigned to the vehicle sensor unit 6 in a stationary manner. If the vehicle 2 and / or the vehicle sensor unit 6 are moved, a corresponding movement of the vehicle monitoring area 8 takes place. By means of the vehicle sensor unit 6, it is therefore possible to detect whether a fire 4, a fire precursor and / or a smoldering fire is present in the vehicle monitoring area 8.

It has proven to be advantageous if the vehicle sensor unit 6 has and / or is a camera, in particular a thermal imaging camera. In this case, the camera can be designed to detect an image 82 of the vehicle monitoring area 8, as is shown schematically by way of example in FIG. 4. If the camera is designed as a thermal imaging camera, the thermal imaging camera can be designed to detect a thermal image of the vehicle surveillance area 8. In addition, the vehicle sensor unit 6 may be designed to evaluate the corresponding image or thermal image and to record the fire characteristic K _{F of} the vehicle monitoring area 8 based thereon.

If the vehicle sensor unit 6 is designed, for example, with a thermal imaging camera, then the vehicle sensor unit 6 can be designed to detect a temperature, in particular for detecting a mean temperature and / or a maximum temperature. The temperature, in particular the average and / or maximum temperature, forms in this case the fire parameter Kp, which is detectable by the vehicle sensor unit 6. In principle, however, it can be provided that the vehicle sensor unit 6 additionally or instead of the camera has a smoke detector, a temperature detector, a flame detector and / or a fire gas detector.

By means of the vehicle 2 should first be checked whether in the fire detector monitoring area 12 actually a fire 4, or a fire precursor and / or a smoldering fire prevails. Therefore, the instruction signal Si transmitted from the central unit 22 to the vehicle 2 represents at least one destination 16 or destination area 137 for the vehicle 2. As an example, the destination 16 and the destination area 137 are shown in FIG. 1 and FIG. The destination 16 or the destination area 137 can therefore be transmitted to the vehicle 2 by means of the instruction signal Si. The vehicle 2 is configured and / or designed to be based on the instruction signal Si, or the Destination 16 represented by the instruction signal Si, or represented destination area 137, to navigate to the corresponding destination 16 or to the destination area 137. By navigation is meant in this sense preferably driving, flying and / or moving. It has proven to be advantageous in this case if the vehicle 2 is designed to autonomously navigate to the destination location 16 or the destination area 137 based on the instruction signal Si. For this purpose, the vehicle 2 has a navigation control unit 18, which is designed to evaluate the instruction signal Si and to control the vehicle 2 based on the instruction signal Si in such a way as to navigate the vehicle 2 in a controlled manner to the destination location 16 or to the destination area 137.

In FIG. 5, the system 20 and the vehicle 2 are shown schematically in such a way that the vehicle 2 has traveled to the destination 16. As can be seen from the synopsis of FIGS. 1 and 2, it is preferably provided that the vehicle 2 is designed as a land vehicle. For this purpose, the land vehicle may thus have tires 46, for example. However, other drive means, such as a chain drive, are also conceivable for a land vehicle. Thus, the land vehicle may be designed, for example, in the manner of a robot vehicle.

In an advantageous embodiment, the central unit 22 stores a destination 16 for the fire detector 14 and / or for the fire alarm monitoring area 12. Thus, if the central unit 22 receives the fire alarm signal SB from the fire detector 14, the central processing unit 22 may transmit to the vehicle 2 an instruction signal Si representing the destination 16 corresponding to the fire detector 14. If a plurality of fire detectors 14 are provided for the system 20, as shown schematically in FIG. 6, a corresponding destination 16 can be stored by the central unit 22 for each of the fire detectors 14 and / or for each of the associated fire detector monitoring areas 12. If a fire alarm signal SB is now transmitted to the central unit 22 by one of the plurality of fire detectors 14, the instruction signal Si transmitted from the central unit 22 to the vehicle 2 can represent the destination 16, which corresponds to the respective fire detector 14 or fire alarm monitoring area 12.

The destination 16 is characterized in that the vehicle monitoring area 8 in at least sufficient overlap with the fire alarm monitoring area 12th is when the vehicle 2 is at the destination 16. In other words, the destination 16 is selected such that, when the vehicle 2 is at this destination 16, there is an overlap, preferably sufficient overlap, from the vehicle monitoring area 8 with the fire alarm monitoring area 12. Preferably, the vehicle surveillance area 8 is in sufficient overlap with the fire alarm monitoring area 12 if at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, or at least 90 %> of the fire alarm monitoring area 12 in overlap with the vehicle monitoring area 8. The overlap here preferably relates to the intersection 48 between the vehicle monitoring area 8 and the fire detector monitoring area 12 (see, for example, FIG. 5). If the vehicle 2 is thus at the destination 16, then the desired sufficient overlap of the vehicle monitoring area 8 with the fire detector monitoring area 12 occurs.

From Fig. 6 it can be seen that for each of the fire detectors 14, a separate signal line 36 may be provided. Each of the signal lines 36 extends from an associated fire detector 14 to the central unit 22. An alternative signal connection between the fire detectors 14 and the central unit 22 is shown in FIG. Here, the central unit 22 and the fire detectors 14 are connected by means of a, preferably single, wired signal line 36 in series. As shown by the dashed line portion of the signal line 36, the signal line 36 may be formed annular. Alternatively, it may be provided - and in this case without the section shown in broken lines - that the signal line 36 leads as a kind of spur line from the central unit 22 to the fire detectors 14. If a wired signal connection 36 is used to transmit the fire alarm signal S _B , then the fire alarm signal S _B can be represented and / or modeled by a current signal and / or voltage signal. For this purpose, for example, the current intensity and / or the voltage potential of the fire detector 14 are adapted to transmit the fire alarm signal S _B ZU. If the wired signal connection 36 leads from the central unit 22 to the plurality of fire detectors 14, whereby the fire detectors 14 are connected in series by means of the wired signal connection 36, then often no clear identification can take place, from which of the majority of the fire detectors 14 the fire alarm signal S _B resp the corresponding change of the Current or the voltage comes. As an advantageous alternative has therefore been found when the wired signal connection 36 is formed as a bus line. In this case, the central unit 22 and each of the plurality of fire detectors 14 each constitute a bus subscriber. Each bus user can have his own bus address, which is also referred to as identifier. Overall, therefore, a bus system for the transmission of information can be formed by the bus users and the bus line. Preferably, the bus system is designed as a ring bus system. The information is, for example, the fire alarm signal or represents the fire alarm signal. Thus, a fire detector 14 can send the fire alarm signal S _B to the central unit 22 by means of the bus line 36 or the bus system. In this case, the address of the respective fire detector 14 can be transmitted. The transmission can take place, for example, in bit-serial form and in the half-duplex method. The fire alarm signal S _B or the associated data information from the fire detector 14 is modulated onto a bus supply voltage provided by the central unit 22. The central processing unit 22 demodulates the respective signals so that the central processing unit 22, the fire detection signal S _B is available. In addition, the central unit 22 acquires knowledge of which the fire detector 14 has sent the fire alarm signal S _B to the central unit 22.

By way of example, the vehicle 2 illustrated in FIG. 6 is also shown in an advantageous embodiment, according to which the fire-extinguishing unit 100 has an extinguishing-agent-generating device 134 for generating the extinguishing agent. For example, the extinguishing agent generating device 134 may have a solid and be designed to ignite the solid, so that a gas and / or a solid aerosol is produced by a corresponding combustion of the solid, the resulting gas and / or the resulting aerosol serving as the extinguishing agent. The extinguishing agent generating device 134 may be connected to the nozzle 102 of the fire extinguishing unit 100 by means of a fluid line connection 136.

As previously explained, the vehicle sensor unit 6 of the vehicle 2 is designed to detect a fire parameter K _{F of} the vehicle monitoring area 8. Since there has now been sufficient overlap of the vehicle monitoring area 8 with the fire detector monitoring area 12 since the vehicle 2 is at the destination 16, For example, by means of the vehicle 2 or by means of the vehicle sensor unit 6 of the vehicle 2, a fire parameter K _{F of} the fire detector monitoring area 12 can be detected, whereby this detected fire parameter K _{F forms} the Verificationbrandkenngröße K _v . In other words, the vehicle 2 is configured to detect the fire characteristic K _F at the destination 16 by means of the vehicle sensor unit 6 as a verification fire parameter Ky of the fire detector monitoring area 12.

After the verification fire parameter Ky of the fire detector monitoring area 12 has been detected, there are now two independently recorded fire parameters, namely the reference fire parameter K _R and the verification fire parameter Ky for the fire detector monitoring area. As explained above, however, it is preferably provided that the fire detector 14 is designed as a fire gas detector, whereas the vehicle sensor unit 6 of the vehicle 2 preferably has a camera or is formed thereof. These independently determined fire characteristics K _R , K _f are difficult to compare. It is therefore provided that the vehicle 2 is designed to determine a further fire condition, which is referred to as verification fire condition Z _v , by evaluating the verification fire indicator variable Ky.

For this purpose, the vehicle 2 may have an evaluation unit. The evaluation unit is preferably designed to evaluate the Verificationbrandkenngröße Ky. In addition, the evaluation unit is preferably designed to determine the verification fire state Z _F based on the result of the evaluation. A Verifikationsbrandzustands Z _F represents, for example, a fire 4, a fire precursor and / or a smoldering fire. In the case of a fire 4, a fire precursor and / or a smoldering fire, characteristic temperatures often occur that can be detected, for example, by the vehicle sensor unit 6. In this context, it should be noted that the collection may also include indirect coverage. If, for example, an infrared spectrum is detected by the thermal imaging camera, then based on this a temperature, in particular a maximum and / or average temperature, can be deduced. FIG. 7 schematically illustrates an exemplary value profile of the verification firing parameter Ky over the time t. At least one threshold value Ws ₄ , preferably a plurality of threshold values Ws ₄ , Wss, Ws ₆ , may be stored by the vehicle 2, and preferably by the associated evaluation unit. These threshold values Ws ₄ , Ws ₅ , Ws ₆ can be threshold values for the verification firing parameter Ky, ie, preferably for a temperature detected by the vehicle sensor unit 6. If a verification fire parameter Ky detected by means of the vehicle sensor unit 6 exceeds the first of the threshold values Ws ₄ , this may be characteristic of a smoldering fire, for example. FIG. 8 schematically shows an exemplary state profile of the verification fire state Z _v over the time t and corresponding to the value profile of the verification fire parameter Ky from FIG. 7. Reached and / or the detected verification fire characteristic K _v exceeds the threshold value Ws _4, a reference fire condition Z _R4 can based thereon, are determined, for example, corresponds to a smoldering fire. For example, if a higher verification fire characteristic Ky, ie in particular a higher temperature detected, the verification fire characteristic K _v may reach the other threshold values Wss and / or top so that be the characteristic of a fire precursor and a corresponding reference fire condition ZYS can be determined. If the detected verification fire parameter Ky reaches and / or exceeds the further threshold value Ws ₆ , then based on this a verification fire state Z _V6 can be determined, which for example corresponds to a fire 4. Thus, it is preferably provided that the evaluation unit of the vehicle 2 is designed based on the detected Verificationbrandkenngröße Ky, and preferably using at least one threshold Ws ₄ , Wss, Ws ₆ , for determining a Verifikationsbrandzustands Z _v .

The verification firing state Zy, which can thus be determined, preferably corresponds in this case, specifically as a function of the verification firing parameter K _v , to a fire 4, a fire precursor and / or a smoldering fire. The Verifikationsbrandzustand Zy can therefore be compared with the reference fire condition Z _R , which also corresponds to a fire 4, a fire precursor and / or a smoldering fire. It is now possible to check the reference combustion state Z _R and, if appropriate, to determine it as confirmed or verified reference combustion state ZV _R ZU. As previously explained, the instruction signal Si represents at least the destination location 16. Since the transmission of the fire detector signal S _B also provides the information about the reference fire condition Z _R , it is provided that the central unit 22 also transmits the information to the vehicle 2 via the reference firing state Z _R. Therefore, the instruction signal Si is configured such that the instruction signal Si represents the reference fire state Z _R and the destination 16. With the transmission of the instruction signal Si from the central unit 22 to the vehicle 2, the vehicle 2 thus the destination 16 and the reference fire condition Z _{R is} provided. In addition, the vehicle 2 is configured to determine the reference fire condition Z _R as verified reference fire condition ZV _R ZU, in case the reference fire condition Z _R and the verification fire condition Z _v at least sufficiently coincide. The sufficient correspondence can then preferably present when the verification fire condition Zy corresponds to a fire-4 and the reference fire condition Z _R a fire 4 of a fire or smoldering precursor corresponds. Furthermore, the sufficient match may be present if the Verification fire condition Zy and the reference fire condition Z _R correspond respectively to a fire precursor or each to a smoldering fire.

The previously described determination of the verified reference fire state ZV _R therefore only takes place when the verification fire state Zy coincides with the reference fire state Z _R or when the verification fire state Zy corresponds to a more developed fire operation. The verified reference firing state ZV _R can therefore also be designated and / or considered as a verified and / or reliable reference firing state. The verified reference fire condition ZV _R therefore serves as a reliable basis for initiating and / or carrying out follow-up actions.

The vehicle 2 is therefore designed to initiate a fire extinguishing action when the reference fire condition Z _{R has been determined} as a verified reference fire condition ZV _R. Thus, the vehicle 2 may be configured to emit a signal to initiate a fire-extinguishing action representing a fire-extinguishing request. However, it is preferably provided that the vehicle 2 has a fire-extinguishing unit 100 which serves at least indirectly for extinguishing a fire 4 and / or is designed. By means of Fire extinguishing unit 100, the vehicle 2 is thus designed to execute the fire extinguishing action using the fire extinguishing unit 100. The fire-extinguishing unit 100 can be designed for direct and / or indirect extinguishment of a fire 4.

A fire extinguishing unit 100 designed for directly extinguishing a fire 4 is shown by way of example and schematically in FIG. In this case, the fire-extinguishing unit 100 has a nozzle 102. The nozzle 102 is designed for discharging, in particular spraying and / or discharging, an extinguishing agent. The extinguishing agent discharged from the nozzle 102 then serves to extinguish a fire 4. The fire extinguishing unit 100 may be designed to conduct and / or convey extinguishing agent under pressure to the nozzle 102, so that the extinguishing agent is discharged by means of the nozzle 102. in particular sprayed and / or ejected, can be. If the extinguishing agent is, for example, water or an aqueous solution, then the corresponding extinguishing agent can be sprayed out by means of the nozzle 102. On the other hand, if the extinguishing agent is, for example, an extinguishing agent powder, then this can be expelled by means of the nozzle 102. In order to provide the extinguishing agent, the fire-extinguishing unit 100 can have an extinguishant container 104, in particular detachable, in which extinguishing agent is stored. The extinguishing agent can be stored under pressure in the extinguishing agent container 104. This offers the advantage that the extinguishing agent can flow out of the extinguishing agent tank 104 without additional effort. Thus, there is no need for additional electrical and / or mechanical power to convey the extinguishing agent from the extinguishing agent container 104 to the nozzle 102. Rather, the pressurized extinguishing agent can be applied and preferably flow out of the nozzle 102. By the predetermined pressure is preferably meant a pressure which is greater than the atmospheric pressure. For example, the predetermined pressure may be at least 5 bar or at least 10 bar greater than the atmospheric pressure. If the vehicle 2 now receives the instruction signal Si, the vehicle 2 can navigate without delay to the destination location 16 or to the destination area 137. It is therefore not necessary that the vehicle 2 after arriving at the destination 16 or in the destination area 137 and an optionally subsequent determination of the verified reference fire state ZVR must once again navigate to another location to receive extinguishing agent and / or the actual deletion of the Brands 4 to initiate. Rather, the vehicle 2 may be directly at the destination 16, or in close proximity thereto, with the actual fire extinguishing kick off. This allows deletion of the fire 4 without unnecessary loss of time, which prevents a fire from developing. In practice, this can be prevented, for example, that from a smoldering fire without light appearance, a fire 4 with light effect arises. In this case, the vehicle 2 can serve to extinguish the smoldering fire, which is often possible with a small amount of extinguishing agent. This results in minor personal injury or property damage.

9, a further embodiment of the vehicle 2 and the system 20 is shown schematically. In this case, the vehicle 2 on a controllable trip unit 106. The controllable trip unit 106 is also referred to as a trip unit. The trip unit 106 may form part of the fire-extinguishing unit 100. The triggering unit 106 is preferably designed as a controllable valve. Thus, the trip unit 106 may be configured to control an extinguishant flow to the nozzle 102. In this case, the triggering unit 106 is preferably coupled into a fluid line connection 108 between the extinguishing agent container 104 and the nozzle 102, so that an extinguishing agent flow from the extinguishing agent container 104 to the nozzle 102 can be controlled by means of the triggering unit 106. If the extinguishing agent is stored, for example, under a predetermined pressure in the extinguishing agent container 104, the outflow of extinguishing agent from the extinguishing agent container 104 to the nozzle 102 can be controlled by means of the triggering unit 106. In this case, the triggering unit 106 can be configured to release, prevent and / or throttle the extinguishing agent flow to the nozzle 102. By means of the controllable trip unit 106, therefore, the time, the duration and / or the amount of extinguishing agent to be applied can be controlled. If the verified reference fire state Z _{VR has} now been determined by the vehicle 2, the vehicle 2 may be configured and / or configured to control the triggering unit 106 based on the verified reference fire state ZV _R ZU. In this case, the triggering unit 106 can be controlled such that it releases an extinguishing agent flow from the extinguishing agent container 104 to the nozzle 102 when the reference fire condition Z _{VR represents} a fire 4. Thus, a fire suppression can take place immediately after the determination of the verified reference fire condition ZV _R. This offers the advantage that personal injury and / or property damage can be reduced to a minimum. A further advantageous embodiment of the vehicle 2 or of the system 20 is shown schematically in FIG. In this case, the vehicle 2 has an extinguishing agent pump 1 10. The extinguishing agent pump 110 can form part of the extinguishing unit 100. The extinguishing agent pump 110 is preferably designed to convey extinguishing agent. The extinguishing agent pump 110 may be coupled into the fluid connection 108 between the extinguishing agent container 104 and the nozzle 102, preferably between the extinguishing agent container 104 and the triggering unit 106. The extinguishing agent pump 110 may serve to convey extinguishing agent from the extinguishing agent container 104 to the nozzle 102. This is particularly advantageous if the extinguishing agent is not stored under pressure in the extinguishing agent container 104. Furthermore, the extinguishing agent pump 1 10 may be advantageous to increase a range or the throw of the extinguishing agent auszubringenden. For by means of the extinguishing agent pump 1 10, the pressure can be increased, with which the extinguishing agent is directed to the nozzle 102 and / or promoted. Furthermore, provision may be made for the vehicle 2 and / or the fire-extinguishing unit 100 to be or are designed to control the tripping unit 106 and / or the extinguishing-agent pump 110. The control can be carried out based on the verified reference fire state Z _VR .

In connection with FIGS. 1, 5, 6, 9 and 10, the vehicle 2 has been schematically illustrated as a land vehicle. In principle, however, the vehicle 2 can be designed as any type of vehicle 2. In Fig. 1 1, a further advantageous embodiment of the vehicle 2 is shown. Thereafter, the vehicle 2 may be designed as an aircraft, in particular a drone. Preferably, the aircraft has at least one rotor 78. The rotor 78 may be coupled to a plurality of rotary blades 80 to provide the corresponding lift and / or propulsion. Particularly preferably, the aircraft is designed as a helicopter and / or as a multicopter, for example a quadrocopter and / or an octocopter. If the vehicle 2 is designed as an aircraft, this has the advantage that areas which are difficult to reach can also be approached or approached in order to detect a fire parameter Kp or a verification brand parameter Ky by means of the vehicle sensor unit 6. In addition, the aircraft offers the advantage that correspondingly difficult to reach areas can be deleted by means of the fire-extinguishing unit 100. Incidentally, reference is made to the preceding explanations, preferred features, effects and / or advantages in an analogous manner. For the following explanations, reference should preferably be made to FIGS. 4, 10 and 12.

An advantageous embodiment of the vehicle 2 is characterized in that the vehicle 2 is formed at the destination location 16 or in the destination area 137 by means of the vehicle sensor unit 6 for determining a fire location 84. This is particularly advantageous when the vehicle sensor unit 6 is formed with or by a camera.

The fire 84 is the location of the fire 4, the fire precursor and / or the smoldering fire. If the vehicle 2 is at the destination 16, an image 82 can be taken by the fire detector monitoring area 12 by means of the camera of the vehicle sensor unit 6. By evaluating the image 82, preferably by means of an evaluation unit of the vehicle 2, the fire location 84 can then be determined. Because the destination 16 is the vehicle 2 known. From this it is possible to deduce the position of the vehicle sensor unit 6 or of the camera. In addition, by means of triangulation, taking into account the destination 16 and the image 82, the fire location 84 can be deduced so that it can be determined by the vehicle 2. The image 82 can be detected by means of a single image by means of the camera of the vehicle sensor unit 6. However, it can also be provided that by means of the camera of the vehicle sensor unit 6, a plurality of images are taken, each corresponding to different rotational and / or Verschwenkpositionen the camera, the vehicle sensor unit 6 and / or the vehicle 2, the vehicle 2 at least essentially at the destination 16. Thus, the plurality of images can be taken in such a way that during a rotation of the vehicle 2 at the destination 16 and / or during a rotation of the camera or the vehicle sensor unit 6, the corresponding images are taken. From the plurality of images, the common image 82 can then be formed. This image 82 may then serve as a basis for determining the location of the fire 84. As can be seen schematically from FIG. 4, the fire 4, and thus the source of the fire, is shown centrally in the lower third of the image 82. The fire 4 is therefore located obliquely below the vehicle sensor unit 6, as shown by way of example in FIG. In order to capture the most meaningful fire parameter Kp by means of the vehicle sensor unit 6, it is preferably provided that the vehicle 2 is designed to align the vehicle sensor unit 6 in the direction of the fire location 84, in particular when the vehicle 2 is at the destination location 16. A corresponding orientation of the vehicle sensor unit 6 in the direction of the fire location 84 is shown schematically in FIG. 12. In order to enable the alignment of the vehicle sensor unit 6, the vehicle 2 may comprise a rotationally, pivotally and / or length-adjustable alignment device 86 to which at least a part of the vehicle sensor unit 6, in particular the associated camera, is attached, wherein the vehicle 2 is for controlling the alignment device 86 is designed to align the vehicle sensor unit 6, or the associated camera, preferably in the direction of the fire location 84. The alignment device 86 is also referred to as the second alignment device 68. Exemplary embodiments of the vehicle 2 with an alignment device 86 are shown schematically in FIGS. 13 to 14.

The alignment device 86 can have a joint unit 1 12 controllable by an actuator and / or a telescopically length-adjustable device 14, so that by controlling the actuator a rotation, pivoting and / or height adjustment of the vehicle sensor unit 6, or the associated camera, is made possible becomes. In addition, the instruction signal Si may have at least one parameter for the control of the alignment device 86, so that the vehicle sensor unit 6, or the associated camera, can be effected by driving the alignment device 86 based on the said parameter, at least in sufficient overlap with the vehicle monitoring area 8 to bring the fire alarm monitoring area 12 when the vehicle 2 is at the destination.

Alternatively or additionally, provision may be made for the orientation of the vehicle sensor unit 6 in the direction of the fire location 84 to take place by controlled navigation of the vehicle 2 itself. For example, based on the instruction signal Si at the destination location 16, the vehicle 2 may execute a rotation about the vertical axis such that the vehicle sensor unit 6 is oriented in the direction of the vehicle surveillance area 12 and / or the fire location 84. This can be ensured that it is to the desired, at least sufficient overlap between the vehicle monitoring area 8 and the fire detector monitoring area 12 comes.

Furthermore, it has proved to be advantageous if the vehicle 2 is configured to detect the verification fire parameter Ky of the fire detector monitoring area 12 only when the vehicle sensor unit 6 is oriented in the direction of the fire location 84. Thus, based on the instruction signal Si, the vehicle 2 can first travel to the destination 16 and then align the vehicle sensor unit 6 in the direction of the fire location 84, and then at the destination location 16 the fire parameter Kp is detected by the vehicle sensor unit 6 as the verification fire parameter Ky of the fire detector. Monitoring area 12 to capture. This ensures reliable determination of the verification fire parameter K _v for the fire detector monitoring area 12, so that thereupon two independently recorded fire parameters, namely the reference fire parameter K _R and the verification fire parameter Ky, are available for the fire detector monitoring area 12.

As shown by way of example in FIG. 14, the vehicle 2 may also be configured to align the nozzle 102. The alignment of the nozzle 102 takes place so that the extinguishing agent to be ejected from the nozzle 102, in particular to be sprayed and / or ejected, flows in the direction of the fire location 84 in order to extinguish the fire 4 or a fire precursor and / or smoldering fire. The orientation of the nozzle 102 may refer to a height position, a vertical swivel angle and / or a horizontal swivel angle of the nozzle 102 relative to the vehicle 2, for example. Thus, the vehicle 2 may be configured to vertically displace, vertically rotate and / or pivot the nozzle 102, and / or to rotate and / or pivot in the horizontal direction. The orientation of the nozzle 102 may be such that the nozzle 102 is aligned directly with the fire 84. However, it can also be provided that the vehicle 2 is designed and / or configured to take into account a trajectory of the extinguishing agent to be deployed, in particular to be sprayed and / or ejected. Because a trajectory of the extinguishing agent is often parabolic. Due to the explained alignment of the nozzle 102, a particularly effective, fast and / or safe extinguishing of a fire 4, or a fire precursor and / or a smoldering fire, take place in the fire alarm monitoring area 12.

For aligning the nozzle 102, the vehicle 2 and / or the fire-extinguishing unit 100 may have a further alignment device 116. This alignment device is referred to as a first alignment device 116. In this case, the first alignment device 116 is designed as a rotationally, pivotally and / or length-adjustable alignment device. At the first alignment device 116, preferably at an end portion 118 of the first alignment device 116 facing away from the vehicle 2, the nozzle 102 is fastened and / or arranged. In this case, the first alignment device 116 may be designed in the manner of an arm device. The first alignment device 116 may comprise a controllable actuator, by means of which a turning, pivoting and / or height adjustment of the first alignment device 116 can be carried out. In this case, the vehicle 2 and / or the fire-extinguishing unit 100 may be designed and / or configured to control the actuator of the first alignment device 116 in order to achieve the correspondingly controlled turning, pivoting and / or height adjustment. Thus, the first alignment device 116, or the associated arm device, a joint unit 120 and / or a telescopically, length-adjustable device 122 have. The joint unit 120 and / or the telescopically, length-adjustable device 122 can be controlled by the actuator, so that by means of the joint unit 120, a controlled rotation and / or pivoting and by means of the length-adjustable device 122, a height adjustment is possible. The first alignment device 116 has the advantage that the nozzle 102 can be positioned over an obstacle that may be between the vehicle 2 and the source of the fire at the fire location 84. In addition, the first alignment device 116 may be used to pivot and / or rotate the nozzle 102 during deployment of the extinguishing agent to extinguish a potentially extensive fire 4.

In particular for larger buildings 30, it may be useful for the system 20 to have a plurality of stationary fire detectors 14. This is shown by way of example and schematically in FIG. 6. In this case, the plurality of stationary fire detectors 14 may be spaced from each other attached to the ceiling 32. Each of the fire detectors 14 is a fire alarm monitored area 12 assigned. In this case, the fire detectors 14 may be arranged to each other such that fire alarm monitoring areas 12 of adjacent fire detectors 14 overlap and / or overlap. This ensures a particularly secure monitoring of the space 34 of the building 30 for a possible fire 4, a possible fire precursor and / or a possible smoldering fire. Each of the fire detectors 14 is preferably designed and / or formed in an analogous manner, as explained in connection with the previous figures for a single fire detector 14. In addition, it is provided that each of the fire detectors 14 is connected by means of a signal line 36 to the central unit 22. Alternatively, a signal line 36 designed as a signal bus may be provided, as is schematically illustrated, for example, in FIG. 21, with which the fire detectors 14 and the central unit 22 are coupled, so that a fire alarm signal S _{B is} transmitted from a fire detector 14 to the central unit 22 can, wherein the fire alarm signal SB can now also represent the address of the respective fire detector 14.

If a fire 4 now occurs in the fire detector monitoring area 12 of one of the fire detectors 14, a reference fire characteristic KR corresponding to the fire 4 is determined by the corresponding fire detector 14 and based on this a reference fire state ZR is determined. Then, the corresponding fire detector 14 transmits a fire detection signal SB to the central unit 22, said fire detection signal SB representing the corresponding reference fire condition Z _R. If the fire detectors 14 are individually connected to the central unit 22 by means of a respective signal connection 36, the central unit 22 can already determine, due to the parallel connections of the fire detectors 14 with the central unit 22, the fire detector 14 which has transmitted the fire alarm signal SB to the central unit 22. Furthermore, it can be provided that the fire alarm signal SB also represents an identifier which serves to identify the fire detector 14 and / or the fire alarm location of the respective fire detector 14. The identifier is also called the address. Based on the identifier, the central unit 22 can thus close to the location of the fire detector 14. If this information is present, the central unit 22 can be designed to determine a destination 16 for the vehicle 2 based on the fire detector location or on the identifier. The central processing unit 22 is therefore preferably configured to determine the instruction signal Si such that the instruction signal Si at least one destination 16 for the Vehicle 2, in which the vehicle monitoring area 8, when the vehicle 2 is at the destination 16, is in sufficient overlap with the fire alarm monitoring area 12 whose reference fire characteristic K _{R was} detected by the fire detector sensor unit 28 of the fire detector 14, the fire alarm signal SB to the central unit 22 transferred. If the instruction signal Si is transmitted to the vehicle 2, then the vehicle 2 navigates to the corresponding destination location 16. This is shown schematically and by way of example in FIG. 15.

16, a further advantageous embodiment of the vehicle 2 and / or the system 20 is shown schematically. In this case, the fire-extinguishing unit 100 of the vehicle 2 has a coupling device 124. The coupling device 124 is designed for releasable coupling of an extinguishing agent container 104. The coupling device 124 thus serves to connect and / or uncouple a detachable extinguishing agent container 104. If the vehicle 2 is not being used for extinguishing fires, for example, an extinguishing agent container 104, in particular a new one, can be coupled to the fire extinguishing unit 100 or the vehicle 2 by means of the coupling device 124 so that they can be used again to extinguish a fire.

For coupling an extinguishing agent container 104, the vehicle 2 can first navigate to an extinguishing agent container depot 126, in which an extinguishing agent container 104 is provided. This can be seen from the synopsis of FIGS. 16 and 17. If the vehicle 2 has arrived in the extinguishing agent container depot 126, the extinguishing agent container 104 can be coupled by means of the coupling device 124. The extinguishing agent container 104 stores extinguishing agent. It is preferably provided that with the coupling of the extinguishing agent container 104 at the same time a fluid connection 108 to the trip unit 106 of the fire-extinguishing unit 100 is made. Thus, the extinguishing agent from the extinguishing agent container 104 serve to extinguish a fire 4, if necessary.

As explained at the outset, an indirect extinction by means of the vehicle 2 can also be provided for initiating a fire extinguishing action. An embodiment of the vehicle 2 suitable for this purpose is shown schematically in FIG. Thus, it is preferably provided for the vehicle 2 that the fire-extinguishing unit 100 is an externally accessible Output terminal 128 may provide for the provision of extinguishing agent, which is fluidly connectable to a mating terminal 130 of a stationary extinguishing device 132 in order to provide extinguishing agent to the stationary extinguishing device 132. The stationary extinguishing device 132 may also be designated as an extinguishing device 132 or as an extinguishing system. The extinguishing device 132 is preferably a part of the system 20. Thus, the system 20 may include the stationary extinguishing device 132 with the mating terminal 130 configured and / or used for coupling the mating terminal 128 of the vehicle 2. The extinguishing device 132 may comprise at least one, preferably a plurality of extinguishing nozzles 70 for discharging extinguishing agent. Instead of the extinguishing nozzle 70 or the extinguishing nozzles 70, other means may be provided which are suitable and / or designed for dispensing extinguishing agent. If, in the following, an extinguishing nozzle 70 is spoken of, it is therefore also intended to mean another means for discharging extinguishing agent. Each extinguishing nozzle 70 is connected in a fluid-conducting manner to the counter-connection 130 by means of a pipeline 74, so that extinguishing agent can be conveyed from the counter-connection 130 to the respective extinguishing nozzle 70. In principle, a fluid line can be provided, from which the plurality of extinguishing nozzles 70 are fluid-conductively connected to the counter-connection 130, wherein a controllable valve can be provided for each extinguishing nozzle 70 in order to direct a fluid flow to the respective extinguishing nozzle or not. As can be seen by way of example from FIG. 18, a plurality of extinguishing nozzles 70 may be fastened to the ceiling 32. In a particularly preferred embodiment, the extinguishing nozzles 70 are arranged in the vicinity of an object to be protected such that an optimized extinguishing success with preferably minimized quantity of extinguishing agent takes place. The extinguishing nozzles 70 are preferably spaced apart from one another such that a fire 4 can be extinguished in each area or a predetermined area of the space 34 or of the object.

If the verified reference fire condition Z _{VR has been determined} by means of the vehicle 2, provision may be made for the vehicle 2 to navigate to the mating terminal 130 in order then to couple the output terminal 128 to the mating terminal 130. The coupling makes it possible for extinguishing agent from the vehicle 2, in particular from the associated extinguishing unit 100 and / or the extinguishing agent container 104, to be provided to the stationary extinguishing device 132. With the provision of the extinguishing agent may therefore preferably a pump, conduct and / or conveying be meant. If extinguishing agent is now conveyed from the outlet connection 128 to the counter-connection 130, a pipeline network comprising the pipes 74 directs the extinguishing agent to the extinguishing nozzles 70, which then discharge the extinguishing agent, for example to extinguish a fire 4 in the fire detector monitoring area 12.
