Description

Technical Field

[0001] The present invention relates to the technical field of safety warning, and in particular to a traffic safety warning system. Background Art

[0002] Some unstable mountain landforms are prone to geological disasters such as landslides and mudslides after being eroded by rainwater, which poses a huge threat to the safety of residents' lives and property. In the existing technology, most slope monitoring for roads, waterways and railway networks requires special observers to monitor and alarm. This method has poor real-time performance and often cannot make timely and effective early warnings when encountering danger. Even some existing automatic early warning technologies hand over the decision-making power of early warning to special personnel. In addition, there is a lack of electronic warning devices at both ends of disaster-prone sections. When road collapse or landslides affect traffic, disaster information cannot be transmitted to passing vehicles in time, which can easily cause secondary losses after the disaster and seriously affect people's lives and property safety.

[0003] Therefore, there is an urgent need for an instant traffic safety early warning system that does not require human intervention. Summary of the invention
