Intelligent Transportation-HRUI Highway Tunnel Safety System Solution

- Dec 14, 2020-

The tunnel belongs to the special structure section in the expressway. Due to the narrow space of the tunnel and strong closedness, once fires, accidents, congestion and other problems occur, the environment in the tunnel will change drastically. More serious traffic accidents and congestion are prone to occur, which directly affect the health and safety of life and property of people in the car. Therefore, it is very necessary to establish an intelligent and efficient tunnel monitoring system.

The highway tunnel monitoring system mainly considers the real-time image conditions at the entrance, intermediate section, and exit of the tunnel, the detection of traffic and velocity in the tunnel, the detection of the working status of the ventilation equipment, the detection of power equipment parameters, and the traffic monitoring, control and command links. The overall monitoring system can be roughly divided into subsystems such as lighting, ventilation, video monitoring, fire alarm, emergency telephone, computer control, environmental monitoring, traffic control and information notification.
