Description

FIELD OF THE INVENTION [0001] The present invention relates to an evacuation guiding apparatus and an evacuation guiding system including the same,

The present invention relates to a technique of installing an evacuation route in a tunnel so that a plurality of evacuees can intuitively confirm an evacuation direction and can display an evacuation route on a screen, And a system.

As the means of transportation are becoming more sophisticated and faster, citizens who are demanders of road traffic are demanding faster transportation systems. Recently, road construction has been constructed by gridding road networks and lattice roads are being straightened as much as possible. The number of tunnels and bridges is rapidly increasing in Korea, where more than 70% of the country is mountainous, in order to grasp and straighten road construction. The characteristics of the tunnel construction that is evolving along with the improvement of the construction technology are that the tunnel talks are going on. Tunnel field conversation has a very positive effect on the straightening of the tunnel, thus contributing to smooth traffic communication.

However, if an accident occurs in a tunnel that is overturned, the inside of the tunnel is easily blocked from the outside. Accidents within closed tunnel spaces occur in many complex situations. Especially, since a lot of traffic accidents tend to lead to fire, the risk is high when a traffic is stagnant in a closed tunnel and a fire occurs. If an accident occurs in a tunnel that has been interrupted, even if it is a small accident, people who are isolated inside a spatially closed tunnel will be in a very dangerous situation unless the accident situation is quickly identified and corrected quickly. As a result of this, interest in safety in the tunnel is increasing, and it is required to take measures against it.

As shown in FIG. 1, the safety device installed in the tunnel includes a plurality of fans for ventilation and reclamation, speakers for emergency broadcasting, indoor fire hydrants and tunnel lights, emergency lights, CCTVs for guiding in tunnels, Includes connecting corridors and emergency parking. Indoor fire hydrants contain fire hydrants, manual fire extinguishers, emergency telephones, button emergency bells, etc., and are installed at intervals of 50 meters. The evacuation connection passages for vehicles and passengers are installed at an interval of about 500m and are an emergency exit for emergency vehicles, drivers and passengers to be safely evacuated to the opposite tunnel where no fire occurred.

The monitoring CCTV in the tunnel transmits the internal image of the tunnel to the tunnel control station so that the manager can visually confirm and monitor it. In addition, reserve power is provided in the tunnel in case of power failure. The emergency parking area is a temporary place on the side of the road so that when the vehicle is broken while the tunnel is running, the vehicle stops in the tunnel to prevent an emergency situation. Emergency parking is installed at an interval of about 500m, so that the vehicle can be stopped at the emergency parking area in case of an emergency, so that a secondary accident can be prevented.

However, all of the safety devices mentioned above only provide a partial indication of the accidents caused by the emergency situation in the actual tunnel, and allow the evacuation due to the smoke caused by the fire to escape safely in a situation where confused people are confused. can not do it.

Korean Patent Laid-Open No. 10-2009-0008930 (hereinafter referred to as "Prior Art Document 1") discloses a portable flashlight capable of wireless networking with a control room and capable of evacuation in the event of an emergency. According to the prior art document 1, a laser pointer is provided on a flashlight to transmit a laser beam when a fire occurs, thereby allowing the user to confirm the position of the flashlight and to easily locate the user.

In Korean Patent Laid-open Publication No. 10-2011-0080693 (hereinafter referred to as "Prior Art 2"), an LED is added to a guidance direction display device so that the evacuee can see the LED, confirm the guidance direction, The contents for use are disclosed.

However, as described in the prior art documents 1 and 2, it is rather dangerous for a refugee to carry a flashlight and move unconditionally according to the direction of induction when a fire occurs in the tunnel. In other words, it is more important than moving to find the evacuation connection passage installed at an interval of about 500m when an emergency situation occurs in the tunnel, and then moving it after recognizing exactly which direction is safe to move. In addition, in the evacuation situation, many evacuees must recognize the evacuation direction at the same time and move them to prevent the confusion from becoming heavy.
