- the people counters are designed in the manner of a light barrier or a light curtain and equipped to count the persons passing their detection area.
- the people count can be done by image processing, for example a camera is used in CMOS technology.
- the section shown in Fig. 1 of an inventive fire alarm system shows an escape route master F and a people counter P, with a central 12 and a Escape route indicator 13 are connected.
- the escape route detector F contains an optical fire detector 1, for example, a scattered light or a NOTExtinkomsmelder. the extra one Sensors for fire characteristics is extended.
- These additional sensors are a CO sensor 14, which forms the actual heart of the escape route detector F, and a temperature sensor 15; if necessary, a radiation pressure sensor (not shown) can also be provided be provided.
- the CO sensor is therefore considered the centerpiece because by far the largest number of fatalities in fires are due to CO poisoning.
- a suitable CO sensor is described in EP-B-0 612 408 (see also EP-A-0 803 850), NTC thermistors have proven to be suitable as temperature sensors (see the PolyRex smoke detector of the AlgoRex fire alarm system, PolyRex and AlgoRex registered trademarks of Cerberus AG).
- the escape route detector F includes a camera 2 in addition to the fire detector 1.
- the fire detector 1 shown consists in a known manner from a detector insert 3, the in a base (not shown) can be fastened, and from a put over the detector insert 3 Detector hood 4. which is provided with smoke inlet openings 5 in the region of its summit.
- the Detector insert 3 essentially contains an optical module 6 and evaluation electronics 7.
- the optical module 6 consists essentially of a light source in a scattered light detector 8 and a light receiver 9 containing measuring chamber 10, which by not shown Medium against external light is shielded from the outside.
- the optical axes of an infrared or a red or blue light emitting diode (IRED or LED) formed light source 8 and the Light receiver 9 are kinked to each other, with this course and by blinding is prevented, that light rays on direct route from the light source 8 to the light receiver 9 can get.
- the light source 8 sends short, intense light pulses in the ais scattering space designated central part of the measuring chamber 10, wherein the light receiver 9 while the scattering space, but not the light source 8 "sees".
- the light of the light source 8 is scattered by penetrating into the scattering room smoke, and a Part of this scattered light falls on the light receiver 9.
- the receiver signal generated thereby is processed by the transmitter 7.
- the receiver signal is in known manner compared with an alarm threshold and at least one Voralarmschwelle, and the transmitter 7 is when exceeded the following as a fire alarm threshold designated alarm threshold by the receiver signal at an output 11 a Alarm signal off. It is by intelligent signal processing using, for example Fuzzy logic or a neural network, ensures that the delivery of the Alarm signal at the lowest possible smoke levels, but without being too unacceptable Fehialarmen comes.
- the transmitter 7 contains another, below alarm threshold called escape route alarm threshold, which is much higher as the fire alarm threshold and a life-threatening smoke density value of for example 10% per meter corresponds.
- escape route alarm threshold is much higher as the fire alarm threshold and a life-threatening smoke density value of for example 10% per meter corresponds.
- the transmitter 7 must be designed this way be that a correspondingly large dynamic range can be processed.
- the said bit is sent to the central unit 12 of the fire alarm system and optionally to a associated with the relevant fire detector and controlled by this, adjustable escape route display 13 and ensures that the monitored by the fire detector concerned Escape route is blocked, either via central 12 or directly through the with the escape route associated with the detector.
- the latter may, for example, be one of the usual illuminated displays for an emergency exit, which in the case of passability green and in the case of impassability red lights, the colors by corresponding pictograms can be supported.
- the information "escape route uncertain" can also be sent remotely be transmitted to the advancing fire department.
- the transmitter 7 also contains for the CO sensor 14 and and the temperature sensor 15 fire alarm thresholds and additional escape route alarm thresholds, with the escape route alarm threshold of the CO sensor 14, for example, 1000 to 1500 ppm CO and the escape route alarm threshold of the temperature sensor 15, for example, about 60 ° C corresponds.
- the receiver signals of the CO sensor 14 and the temperature sensor 15 and delivers when exceeding the relevant escape route alarm thresholds a corresponding signal to the output 11, so that here also an additional bit for "escape route free” or "escape route unsafe" to the control center 12 or to the detector connected escape route indicator 13 and the escape route in the case of "escape route uncertain" is locked.
- the passenger counter P is formed in the manner of a light barrier or a light curtain and consists for example of two active infrared detectors, each having an active light source and contain a receiver with an evaluation. Such an arrangement is for example in EP-A-0 845 765.
- the passenger counter P either directly or via the escape route detector F is connected to the center 12 and the escape route display 13 counts the flow of people in the relevant escape route.
- the measured value is in the corresponding Evaluation electronics, either in the passenger P or in the escape route detector F or optionally provided in the center 12 is compared with a Alarmserwellenwert be When the escape route indicator 13 is exceeded, it is controlled such that a blockage of the the relevant escape route.
- the passenger counter P can be integrated into the escape route detector F or be installed separately from it.
- the camera 2 is preferably in a connected to the fire detector 1 or to this arranged support member 16 is arranged, which is not shown a stage for processing the camera signals whose output is connected to the transmitter 7.
- the Although camera 2 is always ready to shoot, it does not deliver any pictures of the supervised camera Room to the control center 12. The latter takes place only on the basis of a corresponding command from the control center 12. In this way, the operations manager is given the option of remotely controlled escape routes to control and block them if, in his estimation, they no longer work are safe. In addition, he can observe the events in the escape routes, which injured or unconscious persons can be specifically rescued in a timely manner. It would be also possible to use the camera for people counting.
- the camera 2 can also by exceeding an escape route threshold of Escape route detector F or the person counter P are automatically activated and images to the Send center 12. It is essential that the example formed by a data bus Connection between detector 1 and center 12 in the alarm stage not by image signals the camera 2 is clogged, so that alarm signals from the various sensors at any time and without Delay can reach the center 12. On the other hand, it is at the time where the Sensors have responded and fire alarm has already been triggered, or an escape route alarm threshold has been exceeded, more important that the operations manager to monitor the escape routes because it dramatically improves the chances of saving lives becomes.
- the camera 2 is not structurally connected to the detector 1, but can even at some distance from this be angeordent, but what an additional Wiring effort required.
- a camera 2 is preferably a camera in CMOS technology used, wherein the processor of the detector 1, the images taken by the camera compressed so that these with a frequency of about 5 frames per minute over a usual Data bus can be transmitted, the transmission rate of the occupancy of the Bus is dependent.
- the center 12 may include a computer with suitable evacuation software which all passenger counter P and all fire detectors of the plant, the escape route detectors F and the "normal" fire detectors. are connected A suitable software tool for this purpose is known as "Exodus”.
- the fire detectors provide current information Fire and escape route data and the persons paying P also current escape route data the calculator, which calculates the most favorable escape routes based on this data and the Escape route displays 13 switches accordingly.
- the control center 12 with the computer and the connected peripheral devices forms an evacuation system, which can be supplemented by a fire simulation software.
- a fire simulation software allows in case of fire a simulation of the emergency, what for the planning of the plant and the escape routes or in new or special use of spaces can be very useful.
- Fig. 2 shows a schematic representation of a rectangular staircase S, in which four Side channels G open.
- the staircase S is closed to each side passage G by a door T, an escape route indicator 13 is arranged on each of its two sides.
- the side-rail side Escape route reminder is indicated at 13 and the TDenhaus workede at 13 '.
- escape route detectors F are also installed, where the escape route or the escape route detectors in the staircase S with the side exit emergency exit 13 are connected.
- Each escape route detector F in a side passage G is with the at the Stiegenhausseite of the respective Se- tengang final door T arranged Escape route indicator 13 'connected.
- people counters P are arranged, which are arranged above their proximity Escape route finder F or directly with the on the staircase side of the concerned side corridor G final door T arranged escape route indicator 13 'are connected.
- stairwell S can also be arranged people counter P; but preferably the Flow of people in Stiegenhaus S from the data in Stiegenhaus S and from this branching lateral G calculated
- escape route or the escape route F in Stiegenhaus S is exceeded by an escape route alarm threshold register or if the values of the passenger counter P on an overcrowding of Stiegenhauses S point out, then all assigned sideways escape route displays 13 switched to impassable, bringing the access from the side corridors G in the stairwell S is locked. If an escape route detector F or a passenger counter P in a side corridor G registers an excess of an escape route alarm threshold. then the escape route display 13 'on the staircase side of this side passage closing door T on impassable switched and thus blocked access to this side corridor.
- escape route displays throughout the building or in the individual Floors or building tracts, thus creating the possibility of Commands for locking escape routes from escape route display to escape route display pass on, so that it is ensured that in each case the foremost indication of each escape route indicates its current state.
