  FIG. 1 is an explanatory view showing a schematic configuration of a fire alarm facility having an evacuation guidance function by a flash lamp of the present invention.

  In FIG. 1, for example, an R-type receiver 10 is installed in an administrator room on the first floor of a building where a fire alarm system according to the present invention is installed, and a transmission line (signal line) is connected from the receiver 10 to each floor system. ) 12-1 to 12-n are drawn out, and the analog fire sensor 16 is connected to each of the transmission lines 12-1 to 12-n via the sensor base 14, and in this embodiment, The analog fire detector 16 is provided with a flash lamp 15 that functions as a flashlight.

  The m analog fire detectors 16 provided for each system determined by the transmission lines 12-1 to 12-n are assigned with unique addresses A1 to Am in advance, and the maximum number of addresses per system is 127, for example. Yes.

  FIG. 2 is a block diagram showing a schematic configuration of the receiver of FIG. 1 together with an analog fire sensor with a flash lamp. This is an example, and the separation and integration of each function can be performed arbitrarily. Further, any part or all of each function may be executed by software (program) or may be executed by hardware.

  In FIG. 2, the receiver 10 includes a processor 18, transmission units 20-1 to 20-n, an operation unit 22, a display unit 24, an acoustic alarm unit 25, an alarm area display unit 26, a transfer output unit 28, and a memory 30. Is provided.

  An analog fire detector 16 is connected to the transmission lines 12-1 to 12-n drawn from the transmission units 20-1 to 20-n through the sensor base 14, and signals are transmitted and received according to a predetermined communication protocol. Yes. The sensor base 14 is a device that is installed on the ceiling or the like of the monitoring area and is fitted with the analog fire sensor 16 to install the analog fire sensor in the monitoring area.

  The processor 18 is provided with functions of a reception control unit 32 and an evacuation guidance control unit 34 as functions realized by executing the program.

  The reception control unit 32 transmits a batch AD conversion command signal at a data detection timing of a predetermined cycle for each system determined by the transmission lines 12-1 to 12-n, and the analog fire detector 16 detects smoke or heat as a detection target. The analog detection signal of AD is converted and held as smoke or temperature detection data, and then the detection data held in the analog fire detector 16 is collected by a polling command signal sequentially specifying addresses A1 to Am, The collected detection data is compared with a preset fire threshold value, and when the fire threshold value is exceeded, it is determined that a fire has occurred, a fire alarm is displayed on the alarm display unit 24, and an acoustic fire alarm is output from the acoustic alarm unit 25 In addition, the district display unit 26 displays the district where the fire occurred.

  When the evacuation guidance control unit 34 determines a fire report based on the detection data collected from the analog fire detector 14, the evacuation guidance control unit 34 can safely evacuate to the place where the fire occurred based on the evacuation guidance route information of the building stored in advance in the memory 30. The guidance route and its direction are determined, and the control for sequentially flashing the flash lamps 15 provided in the plurality of analog fire detectors 16 arranged along the determined evacuation guidance route is repeated to display the evacuation guidance route and its direction. Let

  Here, the fire determination by the evacuation guidance control unit 34 is performed when the first fire alarm is detected from the detection data of the analog fire detector 16 (detection of the first alarm), for example, on the first floor of FIG. When the first fire alarm is detected from the detection data of the analog fire detector 16 set with the address A4, two analog fire detectors 16 set with addresses A3 and A5 arranged adjacent to both sides thereof are detected. If the second fire report is detected from the detection data of the analog fire detector 16 at address A5, for example (second report) Detection of fire).

  Incidentally, in response to the fire determination by the evacuation guide unit 34, the reception control unit 32 notifies the second report of the fire alarm.

  When the fire is determined by the evacuation guidance control unit 34, the evacuation guidance route and its direction are determined because the fire is detected by the analog fire detector 16 of the addresses A4 and A5. Therefore, the analog fire detection of the addresses A4 and A5 is detected. The installation location of the device 16 is specified as the location where the fire occurred, the evacuation guide route information of the first floor where the fire has occurred is obtained from the memory 30, the fire occurrence location is set as the starting point, and the evacuation in the direction from the starting point to the emergency exit A sensor address list in which the address of the analog fire sensor 16 arranged along the determined evacuation guidance path is determined and the addresses are arranged in order from the base point in the evacuation guidance direction toward the emergency exit is determined. The control to transmit the flash control signal having the address generated and sequentially read from the sensor address list to the analog fire sensor 16 is repeated. By flash lamp 15 provided in the log fire detector 16 is flashing in sequence toward the evacuation direction, and displays clarity evacuation guidance route and its direction.

  For example, when the analog fire detector 16 at addresses A4 and A5 in FIG. 1 detects a fire F, the emergency exit is in the vicinity of the detectors at addresses A1 and Am with this as the base point of the evacuation guidance route. When arranged in the order of addresses along the route, one is displayed so that the flash lamp 15 is flashed in the order of addresses A3 to A1 so that the evacuation guidance route and its direction D1 can be recognized. The flash lamp 15 is flashed in the order of addresses A6 to Am to display another evacuation guidance route and its direction D2. Of course, the address numbers arranged in the evacuation guide route may not always be in ascending or descending order of the sensor address numbers, so the order of the address numbers corresponding to the evacuation guide route is received in advance for each sensor that has determined a fire. Store in machine 10.

  Further, the evacuation guidance control unit 34 stores the flash lamps 15 provided in the plurality of analog fire detectors 16 installed in the second floor on the second floor that is directly above the first floor, which is the fire occurrence floor, in a predetermined memory stored in the memory 30 in advance. Control of flash driving in order toward the evacuation guidance direction is repeated to display the evacuation guidance direction. For evacuation guidance on the upper floor, since it is not necessary to avoid the location of the fire, the optimum evacuation guidance direction is determined in advance, and flash control of the flash lamp 15 is performed accordingly.

  In addition, the evacuation guidance control unit 34 collects detection data from the analog fire detector 15 in a state where the fire is determined and the evacuation guidance route and its direction are displayed by flash control of the flash lamp 15 to collect the fire. The expansion is monitored, and when a fire alarm is detected from the detection data of another analog fire detector 16, the expansion of the fire is determined, and a safe evacuation guide route and its direction are again determined in response to the expansion of the fire. The evacuation guide path is determined by repeatedly controlling the flash lamps 15 provided in the plurality of analog fire detectors 16 arranged along the determined evacuation guide path in order toward the newly determined evacuation guide direction. And its direction.

  FIG. 3 is a circuit block diagram showing an embodiment of an analog fire sensor equipped with the flash device of FIG. This is an example, and the separation and integration of each function can be performed arbitrarily. Further, any part or all of each function may be executed by software (program) or may be executed by hardware.

  In FIG. 3, an analog fire sensor 16 is detachably attached to a sensor base 14 installed on a ceiling surface by fitting terminals 35a and 35b, and is connected to terminals 45a and 45b of the sensor base 14. The transmission line 12 is connected.

  The analog fire detector 16 includes a processor 36, a detection unit 38, a transmission unit 40, a rectification / noise absorption unit 42, a constant voltage circuit unit 44, a flash drive unit 46, and a flash lamp 15 serving as a flash lamp.

  The processor 36 is provided with functions of a sensor control unit 50 and a flash control unit 52 as functions realized by executing the program.

  Here, a sensor is constituted by the sensor control unit 50, the detection unit 38, the transmission unit 40, the rectification / noise absorption unit 42, and the constant voltage circuit unit 44 of the processor 36, while the preceding control unit 52 of the processor 36 transmits. The flash unit is constituted by the unit 40, the flash drive unit 46, and the flash lamp 15.

  The detection unit 38 detects smoke or temperature due to a fire and outputs an analog detection signal. In the case of smoke detection, a scattered light type smoke detection mechanism is provided, and in the case of temperature detection, a temperature detection element such as a thermistor is provided.

  The transmission unit 40 transmits and receives signals to and from the receiver 10 shown in FIG. 2 according to a predetermined communication protocol. The rectifying / noise absorbing unit 42 makes the connection with the transmission line 12 nonpolar by using, for example, a diode bridge, a Zener diode, or a capacitor, and further suppresses noise.

  When the sensor control unit 50 determines the reception of the batch AD conversion command signal designating the self address from the receiver 10 via the transmission unit 40, the sensor control unit 50 reads the detection analog signal from the detection unit 38 by AD conversion and detects it. When it is determined that a polling command signal, which is a fire data request signal with a self-address specified from the receiver, is stored as data in the internal memory, and subsequently the detection data stored in the internal memory is transmitted to the transmission unit 40 Sends a response to the receiver.

  As the flash lamp 15, for example, a white LED is used, and is exposed at a position where it can be easily seen from the outside, such as the top of the sensor cover. When the flash drive unit 46 receives a flash drive signal from the processor 36, the flash drive unit 46 drives the flash lamp 15 so as to reach a maximum light emission amount for a predetermined short period of time.

  The flash controller 52 outputs a flash drive signal to the flash drive unit 46 when the reception of the flash control signal designating its own sensor address from the receiver 10 via the transmission unit 40 is determined. 15 is pulse-driven to output a flash.

  FIG. 4 is a flowchart showing control processing in the receiver of the present invention. In FIG. 4, when monitoring is started by turning on the receiver 10, initialization, self-diagnosis, reading of various setting information, and the like are executed in step S1. If there is an abnormality in initialization in step S1, the fact is notified on the display unit 24, and the operation is stopped halfway or the process of step S1 is performed again, but the illustration is omitted.

  Then, it progresses to step S2, it is discriminate | determined whether it reached | attained the data detection timing repeated in a predetermined period, and if it arrived at the data detection timing, it will progress to step S3 and will output a batch AD conversion command signal with respect to the analog fire detector 16. Transmits analog signals such as smoke and temperature by AD conversion and holds detection data.

  Subsequently, a polling command signal in which the detector addresses A1 to Am are sequentially specified is transmitted, and detection data is collected by a response from the analog fire detector 16 corresponding to the specified address. Subsequently, the presence or absence of a fire alarm is determined by comparing the collected detection data with a preset fire threshold.

  If it is not a fire, the process proceeds to step S6, where it is determined whether or not polling has ended by specifying the final address Am. If polling has not ended, collection of detection data by polling specifying the next sensor address is repeated in step S4. If the polling end is determined in step S6, the process returns to step S2 and waits for the next data detection timing to be reached.

  If it is determined in step S5 that the first fire has been issued, the process proceeds to step S7 to output a fire alarm. The fire alarm turns on the fire representative lamp of the display unit 24, outputs a fire alarm sound by the acoustic alarm unit 25, and further displays the fire occurrence area on the district display unit 26.

  Subsequently, in step S8, the detection data of the adjacent analog fire detector 16 is collected. Here, the adjacent analog fire detectors are the address Ai-1 immediately before and the address Ai-1 immediately after the address Ai of the analog fire detector in which the first fire alarm is determined in step S5. It means an analog fire detector with Ai + 1 set.

  Of course, it is assumed that addresses are set in the order in which the fire detectors are arranged. If this is not the case, a sensor address list storing sensor addresses in the order of arrangement may be stored in a memory or the like, and sensor addresses on both sides adjacent to each other may be acquired with reference to this list.

  The detection data of adjacent analog sensors is collected by transmitting a polling command signal designating an adjacent sensor address after transmitting a batch AD conversion command signal, as in steps S2 to S4. It is desirable to make the transmission period of the conversion command signal shorter than in the case of steps S2 to S3 in order to accurately grasp the fire situation.

  Subsequently, in step S9, it is determined whether or not the second fire has been detected by comparing the detection data of the adjacent analog fire detector 16 with the fire threshold, and the second fire is determined. Then, a fire is determined in step S10. Along with this fire determination, the second fire report is displayed on the display unit 24.

  Subsequently, based on the fire determination, the evacuation guide route and the direction to the emergency exit starting from the location of the fire are determined from the evacuation guide route information stored in the memory 30 in step S11, and the evacuation guide route determined in step S12. Based on the sensor address list of a plurality of analog fire detectors arranged along the line, a flash control signal designating a sensor address in the order of the sensor address list is repeatedly transmitted to the analog fire sensor 16 on the fire occurrence floor, As a result, the flash lamps 15 provided in the plurality of analog fire detectors 16 arranged along the evacuation guidance path are sequentially driven to flash in the evacuation guidance direction, and the flash repeatedly moves in the evacuation guidance direction. The evacuation guidance route and its direction are displayed.

  Subsequently, the process proceeds to step S13, in which a sensor address list corresponding to a predetermined evacuation guidance route and its direction determined for the immediately upper floor stored in the memory 30 is read out, and the sensor addresses in the order according to the sensor address list. Is repeatedly transmitted to the analog fire detector 16 on the floor where the fire has occurred, whereby the flash lamps 15 provided on the plurality of analog fire detectors 16 arranged along the evacuation guide route on the immediately upper floor cause evacuation guidance. The flash drive is performed sequentially in the direction, and the evacuation guidance route and its direction are displayed.

  Subsequently, in step S14, it is determined whether or not the fire has expanded. Similarly to steps S2 to S4, the fire expansion is determined by collecting polling signals by sequentially transmitting a batch AD conversion command signal and then transmitting a polling signal designating detector addresses in sequence, and detecting the detection data as a fire level threshold value. If a new fire report is determined as compared with, the fire expansion is determined.

  If the fire expansion is determined in step S14, the process returns to step S10, and a safe evacuation guide route and its direction are determined again based on the determination result of the expanded fire alarm, and the evacuation guide route newly determined in step S12. The flash control signal designating the sensor address based on the sensor address list corresponding to is repeatedly transmitted to the analog fire sensor 16 on the fire occurrence floor, and the evacuation guidance route and its direction are displayed.

  If fire recovery is determined in step S15, recovery processing such as canceling the fire alarm and canceling the evacuation guidance using the flash lamp 15 is performed in step S16, and the process returns to step S2.

  FIG. 5 is a circuit block diagram showing another embodiment of the analog fire sensor according to the present invention in which a flash lamp and its driving unit are provided on the sensor base.

  5, the analog fire detector 16 includes a sensor control unit 50, a detection unit 38, a transmission unit 40, a noise absorption / rectification unit 42, and a constant voltage circuit unit 44 of the processor 36, as in the embodiment of FIG. On the other hand, the difference from the embodiment of FIG. 3 is that a flash drive unit 48 and a flash lamp 15 are provided in the sensor base 14 and a flash drive signal from the flash control unit 52 of the processor 36 is fitted to a fitting terminal. The signal lines are connected so as to be sent to the flash drive unit 46 via 35c.

  In this way, by providing the flash drive unit 46 and the flash lamp 15 of the flash device separately on the sensor base 14, the change on the sensor side is compared to the case where the analog fire sensor 15 is provided with all the flash device configurations. Can be minimized. The flash drive unit 46 may be provided on the analog fire sensor 16 side, and only the flash lamp 15 may be provided on the sensor base 14. One or a plurality of flash lamps 15 may be provided around the side surface of the sensor base 14 so that the flash lamp 15 can be confirmed from each direction, or may be configured to be attached to the tip of an indicator member extending outward from the sensor base.

  FIG. 6 is a circuit block diagram showing an embodiment corresponding to the second invention of the present application in which a flash device is provided in the sensor base.

  By providing a flash device in the sensor base 14 in this way, the analog fire detector 60 can use a conventional product having only a detection function without a flash device and need not be changed. Even if it is an existing fire alarm facility, By replacing the existing sensor base with the sensor base 14 of FIG. 6, it is possible to easily display the direction of evacuation guidance by the flash lamp 15 provided on the sensor base 14. Even if an analog fire sensor is not connected to the sensor base, evacuation guidance can be performed by driving a flash lamp in the event of a fire.

  In the above embodiment, one flash lamp is provided on the fire detector or the detector base, but a plurality of flash lamps may be provided to improve visibility.

  In addition, when the flash lamps provided on multiple fire detectors or sensor bases are flash-driven in order to display the evacuation guidance route and its direction, the receiver power supply capacity for the transmission line is set to flash-flash flash drive. It is necessary to make the capacity suitable, but a capacitor or secondary battery with a large capacity is provided in the flash drive circuit and charged in a steady state, and a part of power supply by flash drive is performed from the capacitor or the secondary battery. Thus, evacuation guidance can be performed by flash driving of the flash lamp without significantly changing the power capacity of the receiver. The power source for driving the flash lamp may be driven by supplying a separate external power source for each flash lamp.

  In the above embodiment, the fire alarm is judged by collecting the detection data of the analog fire detector by the receiver based on the batch AD conversion command signal and the polling command signal from the receiver. The fire detector is provided with a function to determine the fire alarm, and when a fire alarm is detected by the analog fire detector, a fire interrupt signal is sent to the receiver, and the receiver searches based on the reception of the fire interrupt signal. The analog fire detector 16 that has transmitted the command signal to determine the fire alarm may be searched, and includes various fire alarm facilities having the function of addressing the fire detector or the detector base from the receiver. .

  In the above embodiment, an analog fire detector is connected to the transmission line from the receiver. However, if the monitoring area is large or the number of analog fire detectors is large, One or more repeaters are installed via a transmission line, and an analog fire sensor provided with a flash lamp, for example, is connected to one or more transmission lines drawn from the repeater via a sensor base. May be.

  In this case, the repeater has an interface circuit unit for transmitting and receiving signals to and from the receiver, a processor 18 having the functions of the reception control unit 32 and the evacuation guidance control unit 34 shown in the receiver 10 of FIG. A configuration similar to that of the transmission units 20-1 to 20-n from which the lines 12-1 to 12-n are drawn out may be provided. In this case, the reception control unit 32 functions as a relay control unit, and when a fire alarm is determined, a fire alarm signal is sent to the receiver side to cause a fire alarm. An R type having a function or a P type having a line reporting function may be used.

  Moreover, although the said embodiment has taken the example of the fire alarm equipment provided with the analog fire detector of the address designation from a receiver, the on-off fire detector which can detect a fire alarm by the address designation from a receiver The same can be applied to the fire alarm equipment provided.

  The flash lamp drive is not limited to drive control by repeated transmission of the flash control signal from the fire receiver, but the fire receiver transmits and stores the flash start timing (time) at different times to each fire detector. When the sensor receives the flash start synchronization command from the receiver side, it counts the flash start time stored previously, and then drives the flash so that the flash lamps are lit sequentially in the emergency exit direction. it can. Thereby, the number of signals transmitted from the receiver to each fire detector can be reduced.

  Further, in the above embodiment, the fire detection of the second fire detector is determined to be a fire and the evacuation guidance control is performed by the flash device. Evacuation guidance may be performed from the time of fire judgment, or the threshold of a state that is higher than the fire judgment threshold from the same fire detector (for example, the smoke concentration is deeper than the fire judgment threshold) has been exceeded In some cases, evacuation guidance may be performed.

  In the above embodiment, the receiver and the fire detector are connected by a signal line. However, the present invention is not limited to this, and the present invention can be applied to a mode in which a signal is transmitted wirelessly.

  The timing of the flash drive is not limited to the flash control in order for each fire detector, but the flash control may be sequentially performed in units of a group of a plurality of fire detectors.

The present invention includes appropriate modifications without impairing the object and advantages thereof, and is not limited by the numerical values shown in the above embodiments.
