[0002] Basic transportation facilities, especially dangerous sections of roads, bridges, tunnels, etc., are very likely to collapse, overturn and other serious hazards once they encounter natural disasters. Automatic monitoring and real-time alarm of dangerous situations are particularly important.

[0003] The traditional automatic monitoring and real-time alarm system for dangerous situations monitors the health status of bridges through video surveillance and uploads the data to the emergency command center through a wired network; the emergency command center confirms the degree of danger through data analysis and issues early warning information.

[0004] However, there is a large time difference in the process of video surveillance data reporting, emergency command center data processing, warning information release, etc., and the information delay from the occurrence of a major accident to the audience's awareness is large. At the same time, due to the lack of a real-time alarm module that can reflect the condition of the bridge ahead of the driving road in real time, it is impossible to remind passing vehicles to slow down and stop in the first time, which may cause serious consequences due to untimely warning.
