Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for providing information necessary for ensuring the speed and safety of evacuation of road users and emergency fire extinguishing activities by emergency vehicles in the event of a fire in a road tunnel.

[0002]

2. Description of the Related Art Conventionally, a road tunnel management company grasps the occurrence of a fire using a fire detector or an emergency telephone, and detects the fire based on sensor information such as wind speed, smoke, temperature, gas concentration, etc., and images from a monitoring television camera. Information on evacuation was provided to road users through information display boards, radio rebroadcasting, and loudspeaker broadcasting in tunnels while confirming the progress of the evacuation. In other words, road users had no choice but to rely on simple messages such as information displays, radio rebroadcasts and loudspeakers. Even if a road user can confirm the position of his or her vehicle in a road tunnel using a navigation system, it is difficult to take appropriate evacuation behavior because he cannot know the positional relationship with a fire or an evacuation exit.

[0003] On the other hand, it is difficult for an operator of an emergency vehicle to accurately grasp the positional relationship between the vehicle location and the fire site until the vehicle arrives at the fire site. There was no means to obtain the necessary information, and it was difficult to take appropriate activities.

[0004]

As shown in FIG. 1, a conventional information providing apparatus provides various information collected by a central information providing apparatus to road users by means of an information display board, a loudspeaker broadcast, and a radio rebroadcast. However, due to the limited information provision ability, road users and emergency vehicles were not able to obtain sufficient information, which sometimes hindered proper evacuation and fire extinguishing and rescue operations. . The present invention has been invented in order to meet the demands of road users and emergency vehicle operators.

[0005] Particularly requested information is as follows. (1) Road users (a) I want to know the relationship between the location of the fire and my location. (B) I want to know the size of the fire and the spread of smoke. (C) I want to know the location of the evacuation passage and evacuation pit. (D) I want to know my escape route and time. (E) I want to know the precautions for evacuation. (2) Emergency vehicle operator (f) I want to know the relationship between the position of the fire and the position of the own vehicle. (G) I want to know the size of fire and the spread of smoke. (H) I want to know the presence of general vehicles in a road tunnel. (I) I want to know the location of other emergency vehicles in a road tunnel. (Nu) I want to check the situation inside the tunnel that is invisible to the naked eye with the video of a surveillance TV camera. (R) I want to know the precautions for fire-fighting emergency services.

[0006]

In order to solve these problems, the present invention provides various kinds of information collected by a central information providing device through a wideband communication system and a wideband linear antenna to provide road users with information.
