Definitions

  • the invention relates to a method for detecting a fire in which representative air quantities of the spaces to be monitored are removed via an intake pipe system and sensors for fire characteristics are supplied. Moreover, the invention relates to a device with which in particular the mentioned method can be carried out.
  • Devices of the type mentioned are, for example, from the DE 33 481 07 C2 or EP 1 056 062 B1 already known. These devices remove at certain points of an intake manifold representative quantities of air to be monitored spaces and lead the latter at least one sensor for fire characteristics, under a fire characteristic caused by a fire or fire, measurable environmental change in the form of temperature, temperature rise, smoke, gas evolution, Electromagnetic radiation or the like should be understood. The sensor signals are then examined by an evaluation unit, whereby a fire alarm is triggered if certain criteria are met. With such intake systems In contrast to individual punctiform hazard detectors, large areas of up to 1600 m 2 can be monitored. However, this disadvantage is also counteracted by the disadvantage of less accurate localization of the source of the fire.
  • each pipe is assigned therein a row or column address by providing either a separate detector per pipe or a multi-pipe multiplexer and a detector.
  • each pipe has a suction point at the points of intersection with the other pipes.
  • a location of the source of the fire happens here in that the control unit in the absence of a detection signal, the shut-off valves are set so that all suction simultaneously in open communication with the detector, and switches on receipt of a detection signal in a scanning mode, in which the suction lines one after the other or be brought in groups in open connection with the detector.
  • this procedure for detecting a source of fire presupposes that either each intake point is assigned its own valve or a comprehensive piping system must be installed in order to be able to produce these individually selectable connections.
  • the disadvantage of this is in addition to a fairly high installation effort also the fairly high time required for the necessary queries by opening and closing the valves.
  • an intake system and a method for detecting and locating a fire and / or the occurrence of a fire in one or more monitoring rooms known.
  • a representative air sample is taken from the individual monitoring chambers via a common intake pipe system and fed to at least one detector for detecting at least one fire parameter in the air samples sucked in via the intake pipe system.
  • the aspirated and located in the intake manifold air samples with a blower or suction / blowing device blown out.
  • the invention is therefore based on the object of specifying a method and a device in which the disadvantages identified and described above with reference to the prior art are avoided or at least reduced.
  • a time measurement is started and the first or a second detector is supplied from a second intake pipe end of the intake pipe system.
  • Timing is then terminated as soon as the fire characteristic is detected a second time, the second detection taking place in the detector flowing from the second intake pipe end of the intake pipe system. From the time difference thus obtained between the first recognition and the second recognition and a system-specific location-time function, finally, the suction point, which has recorded the recognized fire parameter, is identified.
  • the room air is sucked in via a pair of intake pipes consisting of a first intake pipe and a second intake pipe which is closely spaced therefrom.
  • air is taken from a monitored space at Ansaugstellencruen, wherein the Ansaugstellencrue consist of one intake on the first and on the second intake manifold and are mounted on the intake manifold so that both intake points of a Ansaugstellencrues similar air samples can be taken from a common monitoring area.
  • the recognizing detector from the first intake pipe has been flown during the first recognition of the fire parameter
  • the recognizing detector from the second intake pipe is supplied with the second detection of the fire parameter and vice versa.
  • the flow directions in the region of the intake points in the first and second intake pipes run simultaneously in opposite directions and are directed towards the first and second detectors. From the time difference between the first and second recognition of the fire characteristic is then closed by means of a suitable location-time function on the location of the intake pair, on which the fire parameter was recorded. In this way, the steps of separate blowing out and renewed suctioning, which are also necessary in the state of the art, can be dispensed with while at the same time requiring moderate installation effort.
  • a switching device is switched in a switching device after the first recognition of the fire characteristic of the first to the second intake manifold, so that before switching the room air is sucked in via the first intake pipe and after switching over the second intake pipe.
  • the first or a second detector from the second intake pipe end of the intake manifold is now flown. Since the switching takes place here completely non-time critical, also the location of the Ansaugstellenpases is determined over the time difference between the first and second recognition here.
  • the room air is withdrawn via an intake manifold consisting of at least a single intake manifold with multiple suction points distributed thereon, at the first Ansaugrohrende a first detector and at the second Ansaugrohrende there is a second detector.
  • the room air is sucked in so that the first detector is flowed from the first intake pipe end.
  • the flow direction in the intake pipe is reversed. This will be the second Detector with the room air flows and recognizes according to a dependent on the location of the intake, which has taken the fire indicator, dependent time also the fire characteristic. From the time difference between the first and second recognition of the fire characteristic and with the aid of a system-specific location-time function, the location of the suction point, which has recorded the fire parameter, is subsequently identified.
  • the intake of the air takes place from a ring-like installed intake pipe.
  • both Ansaugrohrenden be connected directly to a Ansaugbrandmelder or both Ansaugrohrenden are connected to a lying outside the Ansaugbrandmelders flow switch.
  • the second recognition can take place in the first detector and it is possible to dispense with the second detector.
  • the flow direction in the intake pipe is changed again and the time between the second reversal of the flow direction and a third recognition of the fire characteristic is measured after the second recognition of the fire characteristic and a dependent of the location of the identified suction time waiting time. From this time difference and a corresponding location-time function, either a further intake point, which has also taken up the fire parameter, is identified or the suction point identified first confirmed.
  • the suction points which have taken up the recognized fire characteristics, are in the process variants described above and their modifications in addition the measured time differences taken into account the transport times between individual suction points and the detectors.
  • the transport times are either measured during commissioning of the entire system and kept retrievable in a memory, or they are calculated from flow parameters such as the speed in the individual pipe sections.
  • the flow parameters are either measured or calculated using pipe parameters such as pipe length and diameter. Since the transport times frequently change during the operation of an intake system, stored transport times are corrected on the basis of measured values of an air flow monitoring customary in such systems.
  • the invention also relates to devices for detecting and locating a fire which are suitable for carrying out the method according to the invention.
  • a preferred device consists of a Ansaugbrandmelder, at least one intake manifold system with suction, which take representative air samples from a surveillance area, a time measuring device, a unit for identifying suction, which have received a detected fire characteristic.

Suction point pairs are formed along the intake pipe pair, each consisting of a suction point in the first intake pipe and a suction point in the second pipe, both suction points are mounted so that they can take similar air samples from a common monitoring area.
  • the first and second Ansaugbrandmelder and / or the two intake pipes are arranged so that the flow direction in the region of the suction in the second intake pipe to the flow direction in the first intake pipe is in opposite directions.
  • a device for switching between the first and second intake pipe is provided.
  • the means for switching between the first and second intake pipes is located either in a Ansaugbrandmelder where the first intake pipe to the first intake pipe end of the intake pipe system and the second intake pipe to the second intake pipe end of the intake pipe system is connected or outside the Ansaugbrandmelders in a separate housing and There connected in the same way to the intake manifold and of course additionally connected to the Ansaugbrandmelder.
  • a further advantageous embodiment of the device according to the invention comprises an intake manifold consisting of a single intake manifold with a plurality of suction points, at the first Ansaugrohrende a first detector and at the second Ansaugrohrende a second detector are mounted. Furthermore, this device comprises the following devices: a flow switch, with which the flow direction in the intake pipe can be reversed, a time measuring device and a unit for identifying suction points, which have recorded a detected fire characteristic.
  • the first Ansaugrohrende with a first Ansaugbrandmelder and the second Ansaugrohrende connected to a second Ansaugbrandmelder can be done via a multi-way valve.
  • the multi-way valves also serve as a flow switch.
  • a further advantageous embodiment of the device according to the invention comprises an intake manifold consisting of a single, annularly installed intake manifold with multiple suction points.
  • both Ansaugrohrenden the intake manifold are either connected directly to a Ansaugbrandmelder containing at least one flow switch, or they are connected to a separate flow switch, which in turn is connected to the Ansaugbrandmelder.
  • a further advantageous embodiment of the device according to the invention consists of at least two Ansaugbrandmeldern, at least one Ansaugrohrsystem consisting of at least two intake manifolds with intake points that remove representative air samples from a surveillance area, a time measuring device and a unit for identifying suction, which have received a detected fire characteristic.
  • a first Ansaugbrandmelder is connected via a first multi-way valve to the first end of a first intake pipe.
  • the first intake pipe is further connected at its second end via a second multi-way valve with a second Ansaugbrandmelder and the second Ansaugbrandmelder via the second multi-way valve to the first end of a second intake pipe.
  • the second intake pipe is in turn connected at its second end via the first multi-way valve to the first intake fire detector.
  • the multiway valves also serve as flow switches. This results in a ring of two Ansaugbrandmeldern with two intake pipes, each having its own monitoring area.
  • this device is extended to n intake fire detectors, n intake pipes and n multi-way valves.
  • n intake fire detectors n intake pipes and n multi-way valves.

  • the n-th Ansaugbrandmelder can in turn be connected to an n-th intake pipe and this finally with the first Ansaugbrandmelder.
  • a Ansaugbranderkennungssystem (1) can be seen, with a first and second Ansaugbrandmelder (2, 17), each consisting of a detector (4, 14) for fire characteristics, one fan (3) and one each not shown Control and evaluation unit in a respective housing and with an intake pipe system (23) consisting of a first and second intake pipe (24, 25).
  • the first intake pipe (24) is provided with a first intake pipe end (21) of the intake pipe system (23) and connected to the second Ansaugmelder (17), the second intake pipe (25) with a second intake pipe end (22) of the intake pipe system (23) is connected.
  • Both intake pipes (24, 25) are laid largely parallel to one another and close to the bottom.

  • the location of the suction point pair (7) can thus also be represented as a function of the time difference between the first recognition of a fire parameter in the first detector (4) and a second detection in a second detector (14). It is also obvious that the first detection can also take place in the second detector (14) when a fire occurs closer to it.
  • the location of the Ansaugstellenpases (7), which has received the detected fire characteristic, is after the second detection of the smoke from the measured time difference and a location-time function associated with the intake manifold (23). The time measurement and the determination of the location are performed in one of the Ansaugbrandmelder (2, 17), in a separate, not shown location determination unit or in a fire alarm unit, also not shown.
  • the above-described intake fire detection system (1) has the advantage that the maximum transport times between a suction point pair (7) and one of the two detectors (26, 27) compared with a single system Almost halve intake manifold.

If smoke now occurs at the intake point pair (7), it is transported in the first intake pipe (24) via the first intake pipe end (21) to the single detector (4) and detected there for a first time. Immediately thereafter, the pipe switching device (10) changes from the position (11) shown in solid lines to the position (12) shown in dashed lines.

  • the flow direction (8) is reversed.
  • This is a fan that can only promote air in one direction, connected via a four-way valve (15) with an intake manifold.
  • the valve When the valve is in the position shown in solid, air is sucked in via the intake pipe, while in the dotted position, the opposite flow direction in the intake pipe (5) sets. Since the intake pipe in FIG. 3 is already filled with smoke on the route between the intake point (6) and the first detector, it now moves in the direction (9) to the second detector (14), which now emerges from the second Inlet pipe end (22) is flown.
  • the time required until the second detector can now also detect the smoke is dependent on the distance between the intake point (6), which has received the smoke and the second detector, and corresponds to the time between the first detection of the smoke in the first detector (4) and the second detection in the second detector (14), which is measured.
