  • a fire protection system is understood here to mean any type of system that can be used for the purpose of (preventive) fire protection in buildings, halls, rooms or the like.
  • Such fire protection systems can be, for example, but not exclusively, fire extinguishing systems, spark extinguishing systems, smoke extraction systems, water extinguishing systems and / or a combination of these.
  • Fire protection systems within the meaning of the invention are in particular systems that include a central device and / or one or more decentralized devices and one or more peripheral devices and / or components that are connected to one another and / or to the one or more decentralized Devices and / or are in communicative connection with the central device.
  • fire protection systems must meet regulations that are described in the relevant specifications and / or guidelines. These specifications and / or guidelines specify, among other things, certain values for individual peripheral devices, such as pumps and / or valves, of the fire protection system, which must be checked at time intervals that are usually also determined by the specifications and / or guidelines. In these specifications and / or guidelines it can be stated, for example, that the pipes of a fire protection system used to guide the extinguishing fluid must be checked regularly, for example at periodically repeating intervals, for incrustation and / or corrosion, as well as the leakage that may result from this. sen.
  • a leak is understood to mean the escape of extinguishing fluid from the fire protection system in an amount that has an influence on the ability of the fire protection system to reliably and adequately protect the fire protection area it covers. It should be understood at this point that not every escape of extinguishing fluid from the pipes of the fire protection system is to be assessed directly as a leak, since small amounts of fluid can escape from the pipes without any negative effect on the fire protection system.
  • such measurements can also be carried out by means of ultrasonic probes which are arranged inside the pipes and carry out corresponding measurements there to determine whether the cross-section of the pipe has been reduced by deposits.
  • ultrasonic probes which are arranged inside the pipes and carry out corresponding measurements there to determine whether the cross-section of the pipe has been reduced by deposits.
  • corresponding specifications and / or guidelines require, among other things, regular checks of the pipe wall thickness of the pipes of the fire protection system.
  • the pipe wall thickness is checked here, as corrosion can occur within the raw network over time.
  • the pipe wall thickness can be reduced, which can lead to leakage.
  • reducing the pipe wall thickness can have a negative effect on pipe integrity in the event of pressure surges when the fire protection system is triggered. If the pipe wall thickness is reduced too much, a pressure surge can destroy the pipe at the relevant point, causing this at this point then extinguishing fluid can escape, so leakage can occur.
  • VdS guideline CEA 4001 and the guideline EN 12845 should be mentioned as examples of such specifications and / or guidelines. In these it is specified, for example, that in the case of fluid systems every 25 years and in the case of drying systems after about 12 years, the pipe wall thickness should be checked by means of ultrasound measurement and the incrustation by means of an endoscopic examination in order to ensure that any affected pipes can be rinsed remove the incrustations.
  • section 20.2.2 of the VdS guideline CEA 4001 requires, for example, weekly checks on water extinguishing systems.
  • the weekly tests include a control of the pump start of the pump, which is used to deliver the extinguishing fluid. A test run must be carried out for this purpose, which must last until the normal operating parameters of the drive mode are reached, whereby the ability of the pump to achieve these operating parameters can be checked.
  • section 20.3.4.2 of this guideline also provides for annual pump tests in which the delivery rate of the pump is tested in order to ensure that the pump parameters can guarantee the delivery of the extinguishing fluid necessary for the fire protection system to be ready for protection.
  • Another example is checking the storage height within a fire protection area.
  • the fire protection system and warehouse (height) are adapted to one another in such a way that a correspondingly efficient and reliable fire protection campaign can also be guaranteed for the highest stocks within the warehouse.
  • the storage height measurement also makes it possible to check whether the minimum distance required for the extinguishing fluid distribution between the maximum storage height - i.e. the upper edge of the highest stored goods - and the extinguishing fluid outlets is guaranteed. This can ensure that the fire protection system is ready for protection in this regard as well.
  • the fire protection system's readiness for protection is checked at certain intervals which, depending on the checked factor, can vary between days and even years. Continuous monitoring of the fire protection system's readiness for protection is not provided for in the specifications and / or guidelines.

  • a user can also be an operator of the fire protection system who, for example, operates the fire protection system as a customer of the manufacturer.
  • Other types of users are also conceivable.
  • the extent to which the user accesses the fire protection system through the at least one user terminal can depend on the skills and / or the level of training of the user with regard to the respective fire protection system.
  • the disadvantage of this solution is that the user receives the measurement results individually. This means that although the user receives information about certain deviations between actual and target values, these measured values are not put in relation to one another, so that the interaction of the individual changes within the peripheral devices of the fire protection system is not made available to the user. Furthermore, current facilities do not allow the precise errors to be specified. Instead, it is only determined that there is a fault without identifying it more precisely. This makes it necessary for the user to be present on site in order to precisely identify the error and, if necessary, to rectify it. This makes quick and short-term review and troubleshooting difficult.

  • the method further comprises monitoring the hydraulic state of the fire protection system on the basis of the at least one hydraulic parameter in order to determine whether the fire protection system is ready for protection.
  • a readiness for protection of the fire protection system is to be understood in particular as proper functionality of the fire protection system.
  • the readiness to protect includes in particular the operational readiness of the fire protection system, ie the functionality of being able to switch from an operational readiness state to an operational state in which a fire-fighting action is initiated in the event of a fire. This means that in the event of operational readiness, it is ensured that all components of the fire protection system are in their functional condition. This includes in particular the termination of test runs, the blocking of test circuits, the opening of a fluid supply of an extinguishing system, the automatic starting of pumps for the fluid supply and the like.
  • the fire protection system's readiness to protect can also be understood to mean the effectiveness of the fire protection system.
  • effectiveness is understood here to mean that it is ensured that the fire protection system can carry out the purpose assigned to it.
  • An effectiveness of the fire protection system means, for example, that in the event of a fire, enough extinguishing fluid can be deployed to carry out the planned fire-fighting action, for example to control the fire and / or to contain and / or extinguish the fire.
  • the operational readiness of the fire protection system is basically given, but the fire protection system is inadequately effective due to the deviation of certain values for certain parameters from a target value. These parameters can relate in particular to the pump pressure and / or the incrustation of lines. Both would result in an inadequate fluid supply to the fire protection system and thus inadequate extinguishing functionality. Therefore, this effectiveness of the fire protection system can preferably also be viewed as part of the readiness for protection.
  • the willingness to protect can also include aspects of organizational fire protection.
  • Organizational fire protection includes, in particular, the aspects that relate to requirements that may not be changed beyond certain dimensions or framework values so that the functionality of the fire protection system can be ensured. These points relate in particular to the fire load still to be fought by the fire protection system, which is characterized in particular by aspects such as materials within the fire protection area, storage height of the materials within the fire protection area, adequate extinguishing fluid distribution, fire resistance duration and the like. Other factors can be here in particular concern proper maintenance and / or regular maintenance of the fire protection system. Here it is checked whether the fire protection system meets all the requirements for the fire protection area to be monitored in order to be able to fight any fire incidents.
  • the fire protection system is preferably monitored automatically by means of appropriate sensors and a computer program which is able to determine the readiness for protection of the respective fire protection system.
  • the installation of the system consists of a total of three phases: a setup phase in which the fire protection system is first set up. In this phase it is checked which properties the fire protection system has for the present case. Such properties can include the size of the fire protection system, the size of the fire protection area, the fire load located therein, the property to be protected and the like. On the basis of these properties, the usual standard values for the hydraulic parameters of the fire protection system and / or its components and peripheral devices are first established. The first commissioning is then carried out on the basis of these standard values.
  • the setup phase is followed by an initial phase in which a system-specific hydraulic state is determined based on the standard values.
  • the initial phase thus serves, so to speak, to transfer the hydraulic parameters from the standard values, which are regarded as typical for the corresponding type of system, to real values, which are actually given for the individual fire protection system.
  • the monitoring is trained, so to speak, for the individual setting of the respective fire protection system.
  • the initial phase is followed by a main phase in which the fire protection system is monitored on the basis of the system-specific hydraulic status determined in the initial phase.
  • a hydraulic state that is specific to the fire protection system is understood below to mean a system-specific state of the hydraulics of the fire protection system.
  • a hydraulic state describes in particular the interaction of the various hydraulic parameters of the fire protection system in relation to one another.
  • the target state for the hydraulic state of the fire protection system is a state in which the readiness for protection of the fire protection system can be guaranteed, i.e. in which the hydraulic parameters interact in a way that ensures that the fire protection area monitored by the fire protection system is specified and / or monitored in accordance with guidelines and, in the event of a fire, in a manner can be supplied by the fire protection system with a fire protection action that corresponds to the specifications and / or guidelines.
  • the hydraulic status is determined or determined during the initial phase for each fire protection system system-specifically - that is, individually for the respective fire protection system.
  • the individual condition of the fire protection system i.e. the condition that is given individually for each fire protection system, is initially determined on the basis of the theoretical state of the fire protection system determined in the setup phase. This also allows fire protection systems to be monitored which in their entirety have a hydraulic state that leads to a readiness for protection in accordance with specifications and / or guidelines, but whose individual values may not meet the minimum requirements specified by the specifications and / or guidelines. This can be the case for old systems, for example.
  • This determination of the system-specific - individual - hydraulic state can also include a determination of whether the current - initial - hydraulic state of the fire protection system can (still) guarantee readiness for protection per se.
  • This comparison ensures, on the one hand, that a fire protection system that is ready for protection in accordance with specifications and / or guidelines remains in operation and monitored even if individual values deviate from the target values, but still individually ensure the specified extinguishing fluid requirement.
  • it is prevented that a target state is set inappropriately for fire protection systems with insufficient protection readiness during the initial phase, which supposedly can guarantee the protection readiness, although this is no longer given. This increases the quality of the automated monitoring.
  • the initial phase in which the system-specific hydraulic state is determined, comprises, in a first step, receiving measurement data from at least one sensor that is arranged on one or more peripheral devices of the fire protection system.
  • a peripheral device of the fire protection system is understood here to mean in particular components which are arranged on the fire protection system in order to ensure that it is ready for protection.

  • a temperature sensor can be arranged on the pump, preferably at the outlet of the pump, which measures the temperature of the extinguishing fluid at the outlet of the pump and, in the event of an increase in temperature, can give an indication that the pump is running hot.
  • the sensors can also be sensors that are set up to determine corrosion and / or incrustations on or within the pipes, such as, for example, longitudinal wave sensors, ultrasonic sensors or the like. In this way, incrustations and / or corrosion can be discovered. This can also allow conclusions to be drawn about possible leaks.
  • the sensors arranged in the fire protection system are used to determine corresponding measurement data which are indicative of the state of the respective peripheral device on which the sensors are arranged. In some embodiments, these measurement data can be received centrally or locally at one or more processor devices.
  • the one or more processor devices can be set up, for example, as part of a service device. In some embodiments, the one or more processor devices can also be set up as part of a central device for a fire protection system. In some embodiments, the one or more processor devices can also be set up as separate, decentralized devices. In some embodiments, the one or more processor devices can also be arranged on individual sensors as an alternative or in addition to the central or decentralized arrangement, and communicate with each other.
  • the determination of the hydraulic state also includes generating at least one sensor data set on the basis of the measurement data. Generating a sensor data set is understood to mean, in particular, an evaluation of the measurement data, it being possible for the measurement data to be related to one another.
  • the measurement data from a first sensor can show that extinguishing fluid escapes from the pipes of the fire protection system at a certain point in the fire protection system, and the measurement data from a second sensor show that the pump is therefore working at a higher delivery pressure in order to pass the same amount per unit of time to lead the corresponding pipe, whereby this higher delivery pressure does not have a negative effect on the pump.
  • This is particularly possible because in many guidelines and / or specifications security is provided, according to which the individual peripheral devices must work at least in accordance with the minimum requirements, i.e. above the requirements of the minimum requirements, in order to be able to compensate for such small incidents.
  • the determination further comprises the step of evaluating the at least one sensor data record in order to determine at least one quality indication which is indicative of the quality of the at least one sensor data record.
  • the quality indicator thus indicates how the quality of the sensor data set is assessed, i.e. whether the assessment of the fire protection system's readiness for protection is correct. This is the case when the quality indication is within a certain range, for example in the range of +/- 30%, in particular in the range of +/- 20%, even further in particular in the range, in particular, of +/- 10% Default value moved.
  • the quality indication therefore serves to ensure that appropriate feedback for evaluating the measurement data can be provided during the initial phase of determining the hydraulic state. The provision can be done manually or automatically.
  • the indication of the readiness for protection of the fire protection system during the initial phase can, for example, indicate that this is no longer the case, whereas further evaluation of the sensor data record shows that this assessment is incorrect.
  • the quality indication can be used to indicate that the quality of the sensor data set is insufficient.
  • the quality indication can also include an indication of which part of the sensor data set is inadequate and has therefore led to a supposedly incorrect evaluation of the readiness for protection.
  • the quality indication can too indicate that the sensor data set is of high quality if the evaluation of the evaluation of the readiness for protection by the sensor data set is correct.
  • the method includes establishing at least one hydraulic parameter of the fire protection system that is indicative of the hydraulic status of the fire protection system based on the sensor data set and the quality indication.
