  In the flash device 16 provided with such a two-color flash lamp, when the flash control signal for displaying the evacuation guide route and its direction is received from the control device 10, the blue flash lamp 44a is flash-driven. When the flash control signal for the traffic prohibition display corresponding to the evacuation guidance prohibition route is received, the red flash lamp 44b is driven to flash.

  FIG. 5 is a floor plan view showing an arrangement example of the flash device in the present invention. FIG. 5 shows the 10th floor of a building in which the evacuation guidance system of the present invention is installed. Six elevators 50 are installed in the approximate center of the floor, and are partitioned along a path arranged in a lattice pattern. For example, emergency exits 48a to 48d such as emergency staircases are arranged at the four corners of the building. As shown by circles, flash devices 16 are arranged at predetermined intervals on, for example, a ceiling surface of a passage arranged in the floor.

  FIG. 6 is an explanatory view showing an example of the arrangement of the flash devices in the passage. The flash devices 16 are arranged along the ceiling surface of the passage 51 so as to be in a straight line at a predetermined interval. The plurality of flash devices 16 arranged in this way can be seen in the depth direction of the passage when viewed from a person passing through the passage.

  When a fire occurs, a display operation in which the plurality of flash devices 16 arranged on the ceiling surface are sequentially flash-driven in the evacuation guide direction by a flash control signal from the control device 10 is repeated. You can safely go to the emergency exit by following the passage. The flash device 16 may be installed at a height of the wall surface along the passage 51, or may be disposed on the floor surface or the bottom of the wall surface of the passage 51 in order to ensure visibility against smoke due to fire.

  FIG. 7 is a floor plan view showing an evacuation guidance route, its direction display, and a traffic prohibition route display by the flash device when a fire F occurs on the 10th floor in FIG.

  Fire F that occurred on the 10th floor shows the fire decision from the fire receiver 14 and the place where the fire occurred when the fire receiver 14 determines that the fire is received based on the fire detector's fire detector. Based on the transfer signal, the control device 10 determines the evacuation guide route and the direction for safely going to the emergency exits 48a to 48d from the place where the fire F is generated, and the flash device 16 arranged along the evacuation guide route. A plurality of flash devices are generated so as to generate an address list arranged in the order toward the evacuation guidance direction, send flash control signals addressed in the order of arrangement of the address list to the transmission line, and obtain an evacuation guidance display 52 indicated by an arrow in the figure. The control of repeatedly flashing the lights in order toward the evacuation guidance direction is repeated.

  Specifically, the arrow indicating the evacuation guidance route in FIG. 7 is set as one group, and the address of the flash device 16 arranged as shown in FIG. 5 is obtained for each group, and the obtained address is set in the evacuation guidance direction. The group address list is generated by performing the sorting to be directed, and the group address list is further arranged in a predetermined order to generate one evacuation guidance address list.

  The control device 10 determines a dangerous evacuation guidance prohibition route toward the place where the fire F occurs, for example, determines a passage facing the place where the fire F occurs as the evacuation guide prohibition route, and the flash device disposed there For 16, the flash drive is performed all at once or the flash drive is randomly performed, and a traffic prohibition display (entry prohibition display) 54 indicated by a broken line is performed. This traffic prohibition display 54 can avoid a dangerous action in which an evacuee heading for the emergency exits 48a to 48d accidentally evacuates through the place where the fire F occurs according to the evacuation guidance display 52.

  When the prohibition display 54 is performed, the address of the flash device 16 arranged on the evacuation guidance prohibition route is acquired to generate a prohibition address list, and a plurality of corresponding flash devices 16 are simultaneously generated based on the prohibition address list. Perform a flash or random flash. The simultaneous flash is substantially converted into a simultaneous flash by transmitting a flash control signal in which addresses are sequentially specified to a plurality of flash devices 16 in such a short time that the flash cannot be recognized sequentially. The random flash may be a random flash by arranging addresses randomly when forming an address list and transmitting a flash control signal in which the addresses are specified in the order of the list.

  The evacuation guidance display 52 and the traffic prohibition display 54 by the control device 10 read the addresses in order from the top of the list, using the evacuation guidance address list and the traffic prohibition address list as one address list, and display a flash control signal designating this address. Display by sending sequentially and flashing sequentially. Therefore, when a flash control signal is transmitted from the control device 10, only one flash device that is addressed among the flash devices arranged on the floor is driven to flash, but the afterimage of the human eye Due to the effect, a plurality of flash devices arranged along the evacuation guidance route in order at short intervals can be recognized as a change in light moving in the evacuation guidance direction.

  Further, by shortening the transmission interval of the flash control signal for driving the plurality of flash devices 16 in order, the flash movement speed of the evacuation guidance display 52 near the place where the fire F is generated is increased, and the evacuation is accelerated. By increasing the transmission interval of the flash control signal as it approaches the emergency exits 48a to 48b, a sense of security may be provided by reducing the flash speed of the evacuation guidance display 52.

  FIG. 8 is a floor plan view showing an evacuation guidance display on the eleventh floor, which is the upper floor when a fire occurs on the tenth floor. For the 11th floor, which is the upper floor, there is no need to evacuate by avoiding the location of the fire. Therefore, the evacuation guidance address list and the evacuation guidance address list are prepared in advance, and the evacuation guidance display is based on this. The flash devices 16 arranged in the passage so as to be 52 are repeatedly flash-driven in order toward the evacuation direction.

  FIG. 9 is a floor plan view showing a fire brigade guidance display when evacuation guidance completion is determined. When the completion of evacuation from the 10th floor can be determined according to the evacuation guidance display 52 by the flash device 16 shown in FIG. 7, the control device 10 goes from a predetermined entrance, for example, the emergency exits 48 a to 48 d to the place where the fire F occurs. A fire brigade guidance route and its direction are determined, a fire brigade guidance address list is generated based on this, and a plurality of flashes arranged along the fire brigade guidance route are transmitted by sending a flash control signal addressed according to the address list. The apparatus 16 is repeatedly flash-driven in order, and a fire brigade guidance direction display 56 indicated by a broken line arrow is performed.

  For example, the fire brigade that has entered the fire occurrence floor from the emergency exits 48a to 48d by the fire brigade guidance direction display 56 is arranged on the passage ceiling surface even in a situation where the visibility is not sufficiently heard due to a power failure or smoke. Is repeatedly flashed in order, so that the route to the fire occurrence location and its direction can be recognized, and the fire occurrence location can be quickly reached to perform fire extinguishing activities.

  Also, in situations where people are left behind without being able to evacuate to the floor where the fire occurred, the rescue team guidance direction (rescue team guidance route) toward the room where there is a person in need of rescue is determined, and based on this, the rescue guidance address list And a plurality of flash devices 16 arranged along the rescue team guiding path are repeatedly flash-driven in order in the guiding direction by transmitting a flash control signal addressed according to the address list. The guidance direction is displayed, and it is possible to support the rescue team that has entered from the emergency exit to the target location without fail, and prompt rescue activities can be expected.

  FIG. 10 is a flowchart showing evacuation guidance control by the control panel of FIG. In FIG. 10, when the control panel 10 is turned on and monitoring is started, initialization, self-diagnosis, reading of various setting information, and the like are executed in step S1. If there is an initialization abnormality in step S1, the fact is notified on the display unit 26, and the operation is stopped halfway or the processing of step S1 is performed again, but the illustration is omitted.

  Subsequently, the process proceeds to step S2, where the presence / absence of a fire determination based on the reception of the transfer signal from the fire receiver 14 is detected. When the fire determination is detected, the process proceeds to step S3, and the safety is avoided so as to avoid the location of the fire occurrence. The evacuation guidance route and its direction are determined, and a dangerous evacuation guidance prohibition route and its direction toward the fire occurrence location are determined, and an address list corresponding to each is generated.

  Subsequently, the process proceeds to step S4, and a plurality of flash fire control floors arranged toward the emergency exits 48a to 48d as shown in FIG. 7 by transmitting a flash control signal based on the address list corresponding to the evacuation guide route. The flash device 16 is repeatedly driven in order to perform the evacuation guidance display 52, and is arranged in a path toward the location where the fire F occurs by transmitting a flash control signal based on an address list corresponding to the evacuation guidance prohibition path. The plurality of flash devices 16 are flashed simultaneously or randomly to display the passage prohibition display 54.

  Subsequently, the process proceeds to step S5, where a flash control signal, in which addresses are sequentially specified, is assigned to the fire occurrence floor based on a predetermined evacuation guide route determined for the immediately upper floor stored in the memory 30 and an adris list corresponding to the direction. The flash device 16 is repeatedly transmitted to the flash device 16 in order, whereby the flash device 16 on the upper floor is sequentially flash-driven toward the evacuation guidance direction, and the evacuation guidance direction is displayed.

  Subsequently, in step S6, it is determined whether or not the fire has spread based on the transfer signal from the fire receiver 14. If it is determined in step S6 that the fire has expanded, the process returns to step S3, and a safe evacuation guide route, its direction, and an evacuation guide prohibition route are determined again based on the determination result of the expanded fire report, and an address list is generated. The flash control signal addressed in accordance with the address list corresponding to the evacuation guidance route and the evacuation guidance prohibition route newly determined in step S4 is sequentially transmitted to the flash device 16 in order, and the evacuation guidance display and the traffic prohibition display are performed.

  Subsequently, the process proceeds to step S7, and when it is determined that the evacuation guidance has been completed, the process proceeds to step S8 to determine the guide route of the fire brigade from the predetermined entrance to the fire place and its direction to generate an address list. Based on the list, the flash control signals having addresses sequentially specified are repeatedly transmitted in order to the flash device 16 on the fire occurrence floor, whereby the flash device 16 guides the plurality of flash devices 16 arranged in the fire brigade guide route. The flash drive is sequentially performed in the direction, and for example, a fire brigade guidance direction display 56 as shown in FIG. 9 is performed. If the fire brigade does not perform fire fighting activities that enter the fire floor, steps S8 to S9 are skipped.

  If it is determined in step S10 that the fire has been restored, the flash control of the flash device 16 is stopped in step S11, and the process returns to step S2.

  FIG. 11 is an explanatory view showing another embodiment according to the present invention in which a fire detector with a flash device and a flash device are mixedly connected to a transmission line from a fire receiver.

Functions as the control device 10a.

  The reception control unit 82 transmits a batch AD conversion command signal at a data detection timing of a predetermined cycle for each system determined by the transmission lines 15-1 to 15-n. In response to this, the analog fire detector 60 AD-converts the smoke or heat analog detection signal and holds it as smoke or temperature detection data. Subsequently, the reception control unit 82 collects the detection data held in the analog fire detector 60 by a polling command signal in which the addresses of only the analog fire detector 60 are sequentially specified, and the collected fire detection data is set in advance. Compared to the threshold value, when the fire threshold value is exceeded, it is determined that a fire has occurred, a fire alarm is displayed on the display unit 72, an acoustic fire alarm is output from the acoustic alarm unit 74, and a fire occurs on the district display unit 76 Display districts.

  The evacuation guidance control unit 84, based on the detection data collected from the analog fire detector 60, determines that the fire has been triggered by the reception control unit 82, and a fire occurs based on the building evacuation guidance route information stored in advance in the memory 80. A safe evacuation guide route for the place and its direction are determined to generate an evacuation guide address list, and the flash lamps 64 and the flash devices 16 provided in the plurality of analog fire detectors 60 toward the evacuation guide direction based on the address list. The evacuation guidance display is performed by repeating the control of sequentially flashing the flash lamps provided in.

  Here, in the fire determination by the reception control unit 82, when the first fire alarm is detected from the detection data of the analog fire detector 60 (detection of the first report), two analogs arranged adjacent to both sides thereof are detected. When the detection data of the fire detector 60 is collected intensively and the presence or absence of the second fire alarm is monitored, and the second fire alarm is detected from the detection data of one of the analog fire detectors 60 ( A fire is determined in the second report). Note that the reception control unit 82 notifies the second fire alarm in response to the fire determination.

  When the evacuation guidance control unit 84 detects a fire determination by the reception control unit 82, the evacuation guidance direction is determined by determining an evacuation guidance route in the direction from the fire occurrence point to the emergency exit, and along the determined evacuation guidance route. The addresses of the analog fire detector 60 and the flash device 16 are acquired and an evacuation guidance address list in which addresses are arranged in order from the base point of the evacuation guidance route toward the emergency exit is generated. The flash lamp 64 and the flash lamps of the flash device 16 provided in the analog fire detector 60 are evacuated and guided in a repeated manner. The flash light control signal having the designated address is sequentially read and transmitted to the analog fire detector 60 and the flash device 16. Evacuation guidance is displayed by flashing in order toward.

  Further, the evacuation guidance control unit 84 acquires a plurality of analog fire detectors 60 and the flash devices 16 installed on the immediately upper floor, based on a predetermined evacuation guidance route stored in advance in the memory 80 and the direction of the evacuation guidance address generated. Then, the evacuation guidance display is performed by repeating the control of sequentially reading the flashing control signal having the designated address by reading from the evacuation guidance address list to the analog fire detector 60 and the flashing device 16.

  The evacuation guidance control unit 84 collects detection data from the analog fire detector 60 and monitors the expansion of the fire in a state where the fire is determined and the evacuation guidance display is performed by flash control. When a fire alarm is detected from the detection data of the analog fire detector 60, it is determined whether the fire has spread, and a safe evacuation guide route and direction are determined again in response to the fire spread, and an evacuation guide address list is generated. Then, the evacuation guidance display is performed by repeating the control of sequentially reading the flashing control signal having the designated address by reading from the evacuation guidance address list to the analog fire detector 60 and the flashing device 16.

  Further, when the evacuation guidance control unit 84 detects a fire determination, the evacuation guidance control unit 84 determines a safe evacuation guidance route to the fire occurrence location and its direction, and further determines a dangerous evacuation guidance prohibition route toward the fire occurrence location. A traffic prohibition address list of the plurality of analog fire detectors 60 and the flash device 16 arranged along the line is generated, and flash control is performed simultaneously by transmitting a flash control signal addressed based on the traffic prohibition address list. Alternatively, the display of prohibiting the passage is performed by repeating the flash drive control at random.

  The evacuation guidance control unit 84 also provides a safe evacuation guidance route for the fire occurrence location when the analog fire detector 60 and the flash device 16 are provided with two different color flashlights, for example, when a red flashlight and a blue flashlight are provided.

  FIG. 13 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. 13, an analog fire detector 60 is detachably attached to a detector base 62 installed on the ceiling surface by fitting terminals 85a and 85b, and connected to terminals 95a and 95b of the detector base 62. 14 is connected to the transmission line 15.

  The analog fire detector 60 includes a processor 86, a detection unit 88, a transmission unit 90, a rectification / noise absorption unit 92, a constant voltage circuit unit 94, a flash drive unit 96, and a flash lamp 64 serving as a flash lamp.

  The processor 86 is provided with functions of a sensor control unit 98 and a flash control unit 100 as functions realized by executing the program.

  Here, a sensor is configured by the sensor control unit 98, the detection unit 88, the transmission unit 90, the rectification / noise absorption unit 92, and the constant voltage circuit unit 94 of the processor 86, while the flash control unit 100 of the processor 86 transmits. The flash unit is constituted by the unit 90, the flash drive unit 96, and the flash lamp 64.

  The detector 88 detects smoke or temperature due to fire and outputs an analog detection signal. In the case of smoke detection, for example, 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 90 transmits and receives signals to and from the fire receiver 14 illustrated in FIG. 12 according to a predetermined communication protocol. The rectifying / noise absorbing unit 92 makes the connection with the transmission line 15 nonpolar by using, for example, a diode bridge, a Zener diode, or a capacitor, and further suppresses noise.

  When the sensor control unit 98 determines the reception of the batch AD conversion command signal designating the self address from the fire receiver 14 via the transmission unit 90, the sensor control unit 98 reads the detection analog signal from the detection unit 88 by AD conversion. When it is determined that the polling command signal, which is a fire data request signal specifying the self-address from the fire receiver 14, is stored in the internal memory as detection data, and the detection data held in the internal memory is determined. A response is transmitted from the transmission unit 90 to the fire receiver 14.

  As the flash lamp 64, 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 96 receives a flash drive signal from the processor 86, the flash drive unit 96 pulse-drives the flash lamp 64 so as to have a maximum light emission amount for a predetermined short period of time.

  The flash controller 100 outputs a flash drive signal to the flash driver 96 and flashes the flash controller 96 when receiving the flash control signal designating its own detector address from the fire receiver 14 via the transmitter 90. The lamp 64 is pulse-driven to output a flash.

  FIG. 14 is a flowchart showing receiver processing including evacuation guidance control in the fire receiver of FIG. In FIG. 14, when the fire receiver 14 is turned on and monitoring is started, initialization, self-diagnosis, reading of various setting information, and the like are executed in step S21. If there is an abnormality in initialization in step S21, this is notified on the display unit 72, and the operation is stopped halfway or the process of step S21 is performed again, but the illustration is omitted.

  Subsequently, the process proceeds to step S22, where it is determined whether or not the data detection timing repeated at a predetermined cycle has been reached. When it is determined that the data detection timing has been reached, the process proceeds to step S23, and a batch AD conversion command signal is sent to the analog fire detector 60. Transmits analog signals such as smoke and temperature by AD conversion and holds detection data.

  Subsequently, in step S24, a polling command signal in which only the sensor address is sequentially specified is transmitted, and detection data is collected by a response from the analog fire sensor 60 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 S26, where it is determined whether or not polling has been completed by designating the last sensor address Am. If polling has not been completed, collection of detection data by polling that designates the next sensor address is repeated in step S24. If the polling end is determined in step S26, the process returns to step S22 and waits for the arrival of the next data detection timing.

  If it is determined in step S25 that the first fire is detected, the process proceeds to step S27 and a fire alarm is output. The fire alarm turns on the fire representative lamp of the display unit 72, outputs a fire alarm sound by the acoustic alarm unit 74, and further displays the fire occurrence district on the district display unit 76.

  Subsequently, in step S28, detection data of the adjacent analog fire sensor 60 is collected. Here, the adjacent analog fire detectors are the address Ai-1 immediately before and the address Ai-1 next to the address Ai of the analog fire detector in which the first fire alarm is determined in step S25. 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 adjacent sensor addresses may be obtained by referring 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 S22 to S24. It is desirable for the transmission period of the conversion command signal to be shorter than in the case of steps S22 to S23 in order to accurately grasp the fire situation.

  Subsequently, in step S29, it is determined whether or not the second fire has been detected by comparing the detection data of the adjacent analog fire detector 60 with the fire threshold, and the second fire is determined. Then, a fire is determined in step S30. Along with this fire determination, the second fire report is displayed on the display unit 72.

  Subsequently, based on the fire decision, the evacuation guide route toward the emergency exit starting from the location of the fire and its direction are determined from the evacuation guide route information stored in the memory 80 in step S31, and the evacuation guide route determined in step S32 A list of addresses of the analog fire detector 60 and the flash device 16 arranged along the line is generated, and a flash control signal designating the detector address and the flash device address in order based on this address list is sent to the analog fire of the fire occurrence floor. By repeatedly transmitting to the sensor 60 and the flash device 16, the flash lamp 64 provided in the analog fire detector 60 and the flash lamp provided in the flash device 16 are repeatedly flash-driven sequentially in the direction of evacuation guidance, and evacuation guidance is performed. Display is performed.

  In step S31, an evacuation guidance prohibition route is determined together with the evacuation guidance route and the direction thereof, and the analog fire detector 60 and the flash lamp of the flash device 16 corresponding to the evacuation guidance prohibition route are flashed simultaneously or randomly. It is also possible to specify to prohibit the display of traffic.

  Subsequently, the process proceeds to step S33, in which a predetermined evacuation guide route determined for the immediately upper floor stored in the memory 80 and the address list of the sensor and flash device corresponding to the direction are read out, and the sensor address in the order of this address list. The flash control signal designating the flash device address is repeatedly transmitted to the analog fire sensor 60 and the flash device 16 on the fire occurrence floor, thereby evacuating the flash lamps provided on the analog fire sensor 60 and the flash device 16 on the immediately upper floor. The flash drive is sequentially performed in the direction of guidance, and an evacuation guidance display is performed.

  Subsequently, in step S34, it is determined whether or not the fire has expanded. As in steps S22 to S24, this fire expansion is also determined by collecting polling signals by sequentially specifying sensor addresses, collecting detection data, and comparing the detection data with a fire level threshold value to generate a new fire alarm. If fire is determined, fire expansion is determined.

  If it is determined in step S34 that the fire has expanded, the process returns to step S31, and a safe evacuation guide route and its direction are determined again based on the determination result of the expanded fire alarm, and a corresponding address list is generated. The flash control signal designating the detector address and the flash device address in the order in accordance with the newly generated address list is repeatedly transmitted to the analog fire detector 60 and the flash device 16 on the fire occurrence floor to display the evacuation guidance display. .

  If fire recovery is determined in step S35, recovery processing such as canceling the fire alarm and canceling the evacuation guidance display by flash control is performed in step S36, and the process returns to step S22 again.

  If it is determined that the evacuation guidance has been completed between steps S34 and S35, the rescue team is guided to the place where the fire brigade guidance direction display or rescue is being requested to guide the fire team from the predetermined entrance to the fire occurrence location. The rescue team guidance direction display may be performed as necessary.
