Abstract

The invention provides a road accident monitoring system, which is used for monitoring the collision between a vehicle and a road barrier to perform emergent road accident management. The road accident monitoring system comprises at least one collision data acquiring node, at least one collision image acquiring node and at least one remote monitoring control terminal, wherein the at least one collision data acquiring node is used for acquiring collision data produced by the collision between the vehicle and the road barrier, and sending a trigger signal according to the collision data; the atleast one collision image acquiring node is used for receiving the trigger signal from the at least one collision data acquiring node, and is triggered by the trigger signal to acquire collision images of the vehicle and the road barrier; and the at least one remote monitoring control terminal is used for receiving the collision images from the at least one collision image acquiring node to perform the emergent road accident management. The technical scheme can implement the real-time monitoring of the road barrier.

Description

technical field [0001] The invention relates to monitoring technology, more particularly to a road accident monitoring system. Background technique [0002] For highway accident detection, the video monitoring method is generally used, and the highway accident detection model system based on traffic behavior. [0003] Current common solutions include the following: [0004] (1) Video accident detection system [0005] The cameras installed on the roadside can monitor the traffic flow and event status of the expressway locally, and transmit data through optical fiber, optical cable and other carriers, so as to manually judge whether the accident occurred or not. [0006] (2) Freeway Accident Detection Model System Based on Traffic Behavior [0007] Anomalies in expressway traffic usually cause changes in traffic flow detection information. Advanced information processing methods are used to process the detection information (time series) to detect abnormal traffic informat...
