   Conventionally, evacuation guidance in the event of an emergency such as a fire in a building has been performed using a guide light provided at a predetermined location as a mark. Therefore, in the case of an emergency, the evacuee was evacuating by judging the direction of evacuation by himself using the guide light as a landmark.

   The guide lights are provided at necessary locations such as passages used for evacuation, upper entrances of stairs, passage floors used for evacuation, and the like based on the provisions of fire fighting laws. The guide light is always lit, and can be lit for a certain time from the time of power failure by receiving power supply from an emergency power source such as a battery in the event of a power failure.

  The first device (guide light) used for conventional evacuation guidance has conventionally used a fluorescent lamp as the light source, but instead of this, a cold cathode fluorescent lamp is used to save power during a power outage. (Patent Document 1) is provided. In order to check its function, the device of Patent Document 1 is configured to return the state of the device when receiving an inspection signal with an address from the outside.

  Further, as a second device used for evacuation guidance, there is provided a device in which a light source indicating an evacuation direction is turned on when a fire detection signal is input from a fire detector (Patent Document). 2). In this device, LEDs are used as light sources, and the LEDs are arranged in an arrow shape to indicate the evacuation direction.

  Furthermore, as a third device used for evacuation guidance, a display unit, a lighting unit, wireless control means, etc. are provided so that display data given by radio can be displayed on the display unit, and wireless when evacuation is necessary. An evacuation instruction is displayed on the display unit by providing evacuation instruction information, and an evacuation guide can be provided (Patent Document 3).

  First, in the command sending unit 3a, it is assumed that an earthquake is detected by the special vibration sensor 35 and a disaster detection signal related to the earthquake is output. Alternatively, it is assumed that a fire is detected by the special thermal sensor 36 and a disaster detection signal related to the fire is output. When this detection signal is input to the MPU 31, the MPU 31 starts operating (step (S) 101 in FIG. 6).

  Then, MPU31 analyzes a disaster detection signal, forms the evacuation command signal according to the disaster information which the said disaster detection signal has, and drives the transmission control part 32 (S102 of FIG. 6). Thereby, under the control of the transmission control unit 32, the transmission unit 33 issues an evacuation command signal EW1 having a strength that can be received by at least one evacuation guidance unit 5a via the transmission antenna.

In the evacuation guidance unit 5a, the evacuation command signal EW1 is transmitted to the communication antenna 526.

The evacuation command signal EW2 is retransmitted from the transmission means 521 via the communication antenna 526.

The evacuation command signal EW2 retransmitted from the evacuation guidance unit 5a is received by the evacuation guidance unit 5b adjacent to the evacuation guidance unit 5a.
Then, also in the evacuation guidance unit 5b, the same operation as that of the evacuation guidance unit 5a is executed. Then, the evacuation guidance unit 5b again sends out the evacuation command signal EW3.

  The evacuation command signal EW3 retransmitted from the evacuation guidance unit 5b is received by the evacuation guidance unit 5c adjacent to the evacuation guidance unit 5b. Then, also in the evacuation guidance unit 5c, the same operation as that of the evacuation guidance unit 5b is executed. Then, the evacuation guidance unit 5c again sends out the evacuation command signal EW4.

On the other hand, in the command sending unit 3b, an earthquake is detected by the special vibration sensor 35 and a disaster detection signal related to the earthquake is output, or a fire is detected by the special thermal sensor 36 and a disaster detection signal related to the fire is output. When this detection signal is input to the MPU 31 of the command sending unit 3b, the MPU 31 starts its operation (S101 in FIG. 6). Thereafter, the MPU 31 executes a series of operation processes (S102 to S105 in FIG. 6). Thereby, the operation command sending unit 3b operates in the same manner as the command sending unit 3a, and sends out the evacuation command signal EW11. This evacuation command signal EW11 is input to the evacuation guidance unit 5n, and in the evacuation guidance unit 5n, display processing is performed similarly to the evacuation guidance unit 5a, and the evacuation command signal EW12 is retransmitted. Thereafter, the evacuation command signal is finally received up to the evacuation guidance unit 5a, and the evacuation direction is instructed on the evacuation guidance units 5n,..., 5c, 5b, 5a, and the evacuation guidance can be performed reliably.
