Description

  The present invention relates to an evacuation guidance system in a tunnel and emergency equipment in a tunnel that can accurately guide evacuation of a tunnel user in the event of an emergency such as a fire in the tunnel.

  In the tunnel, an evacuation guide light is installed in order to promptly and surely guide people, vehicles, etc. to the exit of the tunnel or the evacuation system in the event of an accident or fire in the tunnel.

  However, in an emergency, users in the tunnel are expected to panic. In addition, there are many cases where the user is not necessarily familiar with the geography in the tunnel, and it is considered that the user cannot settle down and move to the exit of the tunnel or the evacuation center only by displaying the evacuation guide light. Furthermore, there may be situations where it is difficult for the user to identify the evacuation guide light due to the occurrence of smoke, etc. associated with a fire.

  Therefore, in order to quickly evacuate the users in the tunnel to a safe place in the event of a tunnel fire, etc., taking into account the above situation, appropriate evacuation guidance should be given to the tunnel users. It is important to do.

  Therefore, there is a conventional technique that can accurately guide an occupant of a vehicle to escape when an emergency occurs in a closed space such as a tunnel (see, for example, Patent Document 1). The evacuation guidance system according to Patent Document 1 includes a roadside device installed along a road and an in-vehicle device mounted on a vehicle.

  The roadside machine has a function of transmitting to the vehicle position information of facilities corresponding to tunnel exits and evacuation countermeasures. On the other hand, the in-vehicle device has a function of detecting its own vehicle position, searching for the facility closest to its own vehicle position from the location information of the facility received from the roadside machine, and notifying the search result. .

  As a result, the vehicle occupant can receive the facility position information in the traveling tunnel in real time. Furthermore, the occupant can know the facility position for evacuation that is closest to the current position of the vehicle, and can select an appropriate evacuation route and take quick evacuation action when a disaster occurs.

JP 2007-193650 A

However, the prior art has the following problems.
According to Patent Document 1, even when an evacuation guide light cannot be visually recognized, a vehicle occupant can know the nearest evacuation equipment position from the current position of the vehicle, and selects an appropriate evacuation route when a disaster occurs. And evacuate quickly.

  However, the evacuation guidance system according to Patent Document 1 detects its own vehicle position, searches the facility position information received from the roadside machine for the evacuation facility closest to its own vehicle position, and obtains the search result. It is assumed that an in-vehicle device having a notification function is mounted on a vehicle. Therefore, a user of a vehicle not equipped with such an in-vehicle device cannot take a quick evacuation action.

  Moreover, the evacuation guidance system according to Patent Document 1 can provide information on the facility position for evacuation closest to the current position. However, it does not consider the location where a fire or the like occurred. Therefore, when the evacuation facility closest to the current position is in the direction approaching the fire occurrence position from the current position, an appropriate evacuation route cannot always be provided.

  The present invention has been made to solve the above-described problems. When an accident, a fire, or the like occurs in a tunnel and it is necessary to guide evacuation of a person or a vehicle, the present invention is quick and reliable. The purpose is to obtain an evacuation guidance system in a tunnel and emergency equipment in the tunnel that can perform evacuation guidance.

  The evacuation guidance system in the tunnel according to the present invention is arranged in each section in the tunnel, and when a fire is detected, emergency equipment that outputs an operation signal including address information uniquely assigned to itself, Along with the emergency equipment, the position information in the tunnel is transmitted as a first radio signal at predetermined intervals, and an operation signal is sent from any of the emergency equipment provided in each section. If received, a wireless communicator that transmits the fire occurrence position information corresponding to the activation signal as a second wireless signal together with the first wireless signal at predetermined intervals, and a plurality of wireless communications arranged in the tunnel A terminal device for receiving the first radio signal and the second radio signal transmitted from the nearest radio communication device among the devices at predetermined intervals and informing the location information in the tunnel and the location information of the fire occurrence; It is as it has.

  In addition, the emergency equipment in the tunnel according to the present invention is arranged in each section in the tunnel, and when a fire is detected, a fire detection unit that outputs an operation signal including address information uniquely assigned to itself The position information in the tunnel is transmitted as a first wireless signal at predetermined intervals, and when the operation signal is received from the fire detection unit, the fire occurrence position information corresponding to the operation signal is transmitted to the second wireless signal. And a wireless communication unit that transmits the first wireless signal every predetermined period.

  According to the present invention, the current position information in the tunnel and the fire occurrence position information can be wirelessly transmitted to the terminal device in real time, and the owner of the terminal device can take an appropriate action against the fire in the tunnel. It is equipped with the configuration. As a result, when an accident or fire occurs in the tunnel and it is necessary to guide people or vehicles to evacuate, the evacuation guidance system in the tunnel and the tunnel can provide quick and reliable evacuation guidance. You can get emergency equipment.

It is explanatory drawing which shows the condition where the fire broke out in the tunnel in Embodiment 1 of this invention. It is explanatory drawing which showed the structure of the evacuation guidance system in Embodiment 1 of this invention.
