With the development of traffic engineering and transportation, the mileage of traffic tunnels built in China has been rapidly prolonged, the increasing traffic flow, the improvement of the situation and the complexity of transportation items have increased the risk of fires and tunnel pollution sources in traffic tunnels. It has caused many serious catastrophic accidents, especially fire accidents. It not only seriously threatens people's lives and property, but also causes great damage to transportation facilities and human production activities. The intelligent monitoring of tunnels appears to be increasingly The more important.
The monitoring system mainly collects video information (road vehicle conditions and illegal behaviors) in the tunnel, environmental related indicators (such as air quality), traffic flow information (such as the number of passing vehicles in the time period), and passes 3G/4G. The network sends the data to the monitoring center.
