Tunnel traffic accident water curtain warning method and system

Abstract

The invention provides a tunnel traffic accident water curtain warning method and system. Relating to the field of tunnel facilities, information of a traffic operation state in a tunnel is collected;the light is transmitted to a water curtain at the entrance of the tunnel in real time; the traffic operation state in the tunnel is fed back; after an accident happens, a vehicle can be directly reminded of forbidding entering the tunnel from the entrance of the tunnel, effective early warning intervention is carried out on the vehicle about to enter the tunnel, vehicles in the tunnel are reduced, so the vehicles and personnel for rescue can be dispatched to an accident site in time, secondary accidents are avoided, and the safety of non-accident vehicles inside and outside the tunnel is guaranteed.

Description

Technical field [0001] The present disclosure relates to the field of tunnel facilities, in particular to a water curtain warning method and system for tunnel traffic accidents. Background technique [0002] The statements in this section merely provide background technology related to the present disclosure, and do not necessarily constitute prior art. [0003] In modern traffic, tunnels are one of the main types of roads in mountainous or hilly areas. As a semi-enclosed structure, the driver’s field of vision is limited and the escape space is limited. Once the vehicle speeds too fast, it is prone to rear-end collisions. At present, water curtain devices are gradually installed in the tunnel. After a traffic accident occurs, the water curtain is used to softly isolate the accident point, which can prevent the spread of accident smoke, and can also remind subsequent vehicles to avoid the accident point and improve the safety of tunnel operation . [0004] The inventor found that m...

Problems solved by technology

[0004] The inventors found that most of the various facilities in the current tunnel are arranged for follow-up processing after traffic accidents or other abnormal traffic events occur in the tunnel, but cannot provide effective early warning information for vehicles outside the tunnel, and still allow vehicles Entering the tunnel will easily cause traffic jams in the tunnel, affecting the passage of emergency vehicles and the implementation of rescue measures; it may even cause secondary accidents, causing greater casualties and property losses. For some tunnels with curved sections, the curved Parts of the tunnel block the field of vision, resulting in a limited field of vision for the driver, which brings greater risks to longer tunnels and extra-long tunnels; there are few traffic safety warning facilities applied to tunnels, and most tunnels still stay in the conventional traffic signs and traffic signs. The level of warning lines, and the setting of tunnel safety facilities is often blind, which seriously affects the traffic safety level of tunnels
