Description

  The present invention relates to an evacuation guidance system that accurately guides and guides an evacuation route to an evacuee during a disaster such as an earthquake or flood.

  In the event of a disaster, guiding refugees safely and reliably to an evacuation site is extremely important for minimizing damage caused by the disaster. However, when a disaster occurs at night and a power outage occurs, the lighting device in normal times becomes almost useless, and there is a risk that a panic situation may occur in combination with darkness, so do not rely on an external power supply There is a need for an evacuation guidance device.

  In response to such a request, for example, in Patent Document 1, in a guide sign installed on the roadside or facing the road, a solar cell unit is attached to the upper part, side face, or rear face of the sign of the flat housing and displayed on the surface. An all-weather information sign is disclosed in which a light guide plate unit combined with a surface incident light emitting device having a function is placed, and an electric double layer capacitor for a solar cell and a control unit such as light emission / extinction are incorporated. .

  On the other hand, Patent Document 2 discloses a solar battery, a storage battery that stores electric power generated by the solar battery, a light / dark switch that senses light and dark and is turned on only in a dark state, and is connected to the storage battery via the switch. There is disclosed an emergency guide light that includes a decorative light emitter, an emergency switch that is turned on in the event of an emergency, and an emergency light emitter that is connected via the emergency switch.

  In FIG. 7, an emergency light emitter 311 inserted and inserted into the upper surface plate 31 toward the inside of the upper surface plate 31 is made to enter light L <b> 1, and light is emitted in the shape of an arrow 33 on the back surface of the upper surface plate 31. The V-shaped cutting process 312 is performed so that the incident light L1 is refracted upward by the cutting process 312 so that the arrow 33 emitting light from above can be visually recognized. Solar cells 37 are arranged below the upper surface plate 31, and sunlight is transmitted through the transparent upper surface plate 31 to be incident on the solar cells 37. The generated power is generated by the main body 32. The power is stored in the power supply device 36 built in together with the seismic sensor 39, and the stored power is supplied to the emergency light emitter 311 and the normal light emitter 35, so that the road sign 3 emits light.

  Here, the normal light emitter 35 sends a signal to the power supply device 36 when it detects that the brightness sensor 38 disposed below the upper surface plate 31 has become below a certain level in normal times. Flashing light emission or the like is started, but when an earthquake occurs and the seismic sensor 39 detects an earthquake exceeding the threshold value, a signal is transmitted to the power supply device 36, and the power supply device 36 transmits the emergency light emitter 311. To emit light. When the emergency light emitter 311 is caused to emit light, the normal light emitter 35 may continue to emit light. However, if the emergency light emitter 311 is caused to emit light by the power supply device 36 and the normal light emitter 35 is turned off, the light emission is performed. It is possible to save power consumption and to maintain the evacuation guidance function for a long time.
