Description

Technical Field

[0001] The present invention relates to the technical field of traffic safety, and in particular to a monitoring and alarming method and system for sudden route blocking accidents. Background Art

[0002] Traffic network often passes through high mountains, canyons and rivers, so it is necessary to build a large number of bridges, high fill roadbeds, deep slope excavation and other facilities. Due to bad weather conditions, quality defects, other abnormal accidents and other reasons, bridge collapse, roadbed collapse and other accidents often occur. When the traffic network collapses suddenly, if it is not discovered in time and the alarm information is not sent to the oncoming vehicles, cars or trains often fall or collide directly, causing huge casualties and property losses.

[0003] Therefore, whether it is possible to monitor in real time whether a traffic route has a blocking accident, and to promptly issue an alarm message to warn oncoming vehicles on the accident section when a blocking accident such as collapse or burial occurs, is a technical problem that urgently needs to be solved. In the prior art, most of the technical solutions to solve this problem are costly, and due to the changeable environment of the traffic route, various problems will also arise in the related hardware for implementing the technical solution, making it very easy to misjudge the judgment of the blocking accident. For this reason, the present invention provides a monitoring and alarm method and system for sudden route blocking accidents. Summary of the invention
