Description

Road Monitoring System {MONITORING SYSTEM OF ROAD}

The present invention relates to a road monitoring system that detects a fire and an emergency by photographing a road.

In general, the inside of the tunnel is a closed space feature, and if a disaster such as a traffic accident or fire occurs, it will proceed as a bigger accident. Therefore, various sensors are installed in the tunnel at regular intervals to detect and detect the data in real time. As a result, the system is installed and operated to promptly notify and correct accidents to administrators by sending them to the tunnel control room and remote operation centers. In addition, even in the case of bridges, underground tunnels, and underground cavities, it is difficult to prepare for an accident and intensive management is necessary.

In order to monitor such accidents, various surveillance cameras and speed control cameras are installed on the road to transmit the captured images to a remote control room, so that the administrator can visually check and contact the related organizations without taking an accident scene. .

Thereafter, the remote control room checks the transmitted information and alerts the user when an accident occurs, and the administrator manually controls the surveillance camera to accurately check the accident site, and then notifies and responds to the accident.

However, the conventional surveillance camera is a means for simply photographing the situation on the road, and the remote manager must always monitor the naked eye, and the manager must manually operate the surveillance camera after an accident, so precise control when the manager is absent There was a problem that the accident scene that occurred outside the space being photographed by the surveillance camera could not be taken.
