A method and system for early warning of vehicle collision event in construction work area

Abstract

The present invention relates to a method and system for early warning of a vehicle collision event in a construction work area. The method includes the steps of: 1) obtaining millimeter-wave radar reflection data of the vehicle; 2) obtaining real-time running state data of the vehicle by using the millimeter-wave radar reflection data of the vehicle; 3. ) judging whether the vehicle has abnormal driving behavior based on the real-time running status data of the vehicle; 4) sending an early warning signal to the alarm device in the construction area for the abnormal driving behavior of the vehicle judged in step 3). Compared with the prior art, the present invention can provide early warning of rear vehicle collision events for workers in the construction area, realize active protection for the life safety of workers in the construction area, reduce the accident rate in the construction area, and improve the safety of roads in the construction area. level of operational security.

Description

Method and system for early warning of vehicle crash event in construction work area technical field The present invention relates to the technical field of traffic big data application, especially relate to a kind of construction work area vehicle crash event Early warning methods and systems. Background technique [0002] Millimeter-wave radar, as a traffic data acquisition method, has achieved rapid development in the field of traffic, and has been gradually applied. It is used in many aspects such as vehicle anti-collision detection, traffic information collection, unmanned environment perception, etc. The application of road traffic information collection has become more popular, but the application of early warning of high-risk behavior of vehicles is relatively rare. Because the radar detector is easy to install, not affected by the weather, does not damage the road surface, has strong anti-interference ability in complex environments, It has the advantages of...

Problems solved by technology

[0003] The traditional protection measures for road construction areas mainly adopt the method of setting warning information signs, warning lights and road enclosure facilities upstream of the construction area, which can only provide early warning for passing vehicles, and cannot meet the needs of active early warning for construction area operators. It is difficult to monitor the abnormal behavior of vehicles, and warn construction workers in real time to pay attention to the risk of vehicles crashing into construction areas

[0004] At present, there are two main problems in the road vehicle collision warning system in the construction work area. One is that the data collection method mainly adopts the method of video monitoring, and the method of video monitoring is affected by the image processing algorithm, and the recognition accuracy is low and affected by environmental factors. The second is that some early warning systems using radar have a single function. Generally, they only provide early warnings for the most basic abnormal behaviors such as illegal parking or speeding. Early warning systems for various abnormal driving behaviors need to be developed
