[0002] With the rapid development of expressways, tunnels, as an important part of expressways, are receiving more and more attention for their safety issues. After a traffic accident occurs in a tunnel, due to the special environment in the tunnel, secondary accidents are likely to occur, posing a serious threat to people's lives and property. Therefore, how to prevent the occurrence of secondary accidents has become a key issue in the safety management of expressway tunnels. In the prior art, the prevention of traffic accidents in tunnels mainly relies on real-time monitoring and discovery by monitoring personnel, and then early warning and processing are carried out manually. In order to cope with the increase in traffic volume and accidents in expressway tunnels, improve the safety of driving in tunnels, reduce the occurrence of secondary safety accidents, and protect the lives and property of people in tunnels, it is necessary to install a secondary accident early warning device in front of the tunnel door when an accident occurs. The traditional secondary accident early warning device is a fixed structure, including a fixed warning sign and a fixed warning light. When there is no accident, the warning sign needs to be removed or the warning content needs to be deleted. Its disassembly or placement and withdrawal process is inconvenient and unsafe. Therefore, a highway tunnel early warning device for preventing secondary accidents that is easy to use and safe is invented. Summary of the invention
