  Embodiments of an evacuation guidance system and guidance device according to the present invention will be described below in detail with reference to the accompanying drawings.

  FIG. 1 is a diagram showing an example of an evacuation guide path in an evacuation guidance system to which the present invention is applied.

  The evacuation guidance system shown in FIG. 1 is applied to, for example, large-scale stores, hospitals, various facilities, and the like. When a fire occurs in the guidance area 10, this fire occurrence point 20 is specified, and this An evacuation guideway is set so as to avoid the identified fire occurrence point 20, and the guided person 30 is guided to the emergency exit 40 along the evacuation guideway.

  In this evacuation guidance system, in order to guide the person to be guided 30 to the emergency exit 40 along a predetermined evacuation guidance path, a plurality of guidance devices 50 are disposed along a path in the guidance area 10, and the plurality of guidance devices 50 are arranged. Are connected to each other via a communication line 60, and the communication line 60 is connected to a control device 70 having a fire occurrence point identifying unit 71 and an evacuation guideway determining unit 72.

  Here, as will be described in detail later, the plurality of guidance devices 50 are disposed at predetermined intervals on the floor surface, side walls, handrails provided on the side walls of the passage in the guidance area 10, and are generated by generation of vibration, light, and the like. It is used to guide the guided person 30 to the emergency exit 40 along a predetermined evacuation guide path.

  The fire occurrence location identifying unit 71 provided in the control unit 70 identifies the fire occurrence location 20 based on fire occurrence information sent from a well-known fire detection system (not shown).

  The evacuation guideway determination unit 72 holds, for example, map information about a passage in the guidance area 10, and safely guides the person to be guided to avoid the fire occurrence point 20 specified by the fire occurrence point specification unit 71. The evacuation taxiway which can guide to 40 is determined.

  For example, FIG. 1 assumes a guidance area 10 provided with a passage capable of guiding a person to be guided between a plurality of blocks A to G, and the lower right corner of the block A in the guidance area 10. If the fire occurrence point 20 that occurred in is identified by the fire occurrence point identification unit 71 and it is detected that the guided person 30 is in the passage between the block E and the block G, the evacuation guideway determination unit 72 The evacuation guide path that follows the series of guide devices 50 filled in black in FIG. 1 that can safely guide the guided person 30 to the emergency exit 40 while avoiding the fire occurrence point 20 is determined.

  FIG. 2 shows an example of another evacuation guide path determined by the evacuation guide path determination unit 72.

  In FIG. 2, the fire occurrence point 20 in the lower right corner of the block A in the guidance area 10 is specified by the fire occurrence point specifying unit 71, and the guided person 30 is in the passage between the block D and the block E. An example of an evacuation taxiway determined by the evacuation taxiway determination unit 72 is shown. In this case, since the path toward the block A side of the guided person 30 approaches the fire occurrence point 20, there is a danger for the guided person 30, so the evacuation guide path determination unit 72 avoids the fire occurrence point 20, An evacuation guide path is determined to follow the series of guide devices 50 filled in black in FIG. 1 that bypasses the path between the block E and the block F.

  And the evacuation guide route determination part 72 of the control apparatus 70 transmits the guidance information for guiding the to-be-guided person 30 along the determined evacuation guide route to each guide device 50 via a signal line.

  In FIG. 7, the control unit 56 of the guidance device 50 first checks whether a light emission instruction for the light emission unit 54 has been received from the control unit 56 of the guidance device 50 after the guidance direction via the communication line 60 (step 701).

  If a light emission instruction is received (YES in step 701), the light emitting unit 54 is controlled to emit predetermined light from the light emitting unit 54 (step 702).

  If it is determined in step 701 that a light emission instruction has not been received (NO in step 701), then it is checked whether the induced person 30 has been detected by communication with the mobile terminal 100 by the communication unit 55 (step 703). . If the guided person 30 is not detected (NO in step 703), the process returns to step 701.

  If the guided person 30 is detected in step 703 (YES in step 703), guidance information is acquired from the evacuation guidance path determination unit 72 of the control unit 70 (step 704), and the guidance direction is determined. (Step 705).

  Based on the determination result of the guidance direction, a light emission instruction is transmitted to the guidance device 50 before the guidance direction (step 706), and the guided person 30 is transmitted from the communication unit 55 to the portable terminal 100 carried by the guided person 30. Is transmitted (step 707), and then the light emission from the light emitting unit 54 is stopped (step 708), and this process is terminated. Note that the processing of the flowchart shown in FIG. 7 is repeatedly executed at predetermined time intervals.

  FIG. 8 is a flowchart showing the operation of the control unit 103 of the mobile terminal 100 shown in FIG.

  In FIG. 8, the control unit 103 of the mobile terminal 100 checks whether the voice guidance information is received from the guidance device 50 by the communication unit 101 (step 801).

  If no voice guidance information is received (NO in step 801), the process returns to step 801. If voice guidance information is received (YES in step 801), the received voice guidance information is analyzed.

The voice guidance unit 106 is controlled so that the corresponding voice guidance is performed from the voice guidance unit 106.

  For example, when the color identified by the control unit 107 is blue, voice guidance “Please proceed in the direction of the light that is lit in front” is performed, and when it is yellow, “Because it is a branch point, Please proceed with attention to the direction of the light that is lit, and if it is red, the control unit 107 will perform the voice guidance “Please exit from the emergency exit because it is in front of the emergency exit”. Controls the voice guidance unit 106.

  FIG. 11 is a flowchart showing the operation of the control unit 107 of the mobile terminal 100 shown in FIG.

  First, the control unit 107 of the mobile terminal 100 checks whether the light (color signal) emitted from the light emitting unit 57 of the guidance device 50 is received by the light receiving unit 105 (step 1101). (NO in step 1101), the process returns to step 1001, but if it is determined that a color signal has been received (YES in step 1101), color identification of the received color signal is performed (step 1102).

  If the color signal received by this color identification is blue (YES in step 1103), the voice guidance unit 106 is controlled to perform voice guidance for proceeding in the direction of the lit light in front (step 1104), if it is yellow (YES in step 1105), the voice guidance unit 106 is controlled to give a forward voice guidance while paying attention to the direction of the light that is lit ahead (step 1106), and is red. In this case (YES in step 1107), emergency exit voice guidance is performed (step 1108).

  According to such a configuration, a visually handicapped person or the like who cannot identify the color of light emitted from the light emitting unit 57 of the guidance device 50 can be safely guided along the escape guide path.

  In addition, although the said Example demonstrated the evacuation guidance to the emergency exit when a fire broke out, it is applicable similarly to the evacuation guidance when another disaster occurs.

  The present invention can be used for evacuation guidance when a disaster occurs in a large-scale store, a hospital, an airport, various exhibition halls, or the like.
