Method and system for assistant collision avoidance of objects moving to pass through road based on wireless coordination

A moving object and wireless technology, applied in the field of intelligent transportation, can solve the problems of only detecting objects directly in front of the moving direction of the vehicle, the effective working distance of the sensor is short, and the inability to detect moving objects in advance, so as to expand the scope of detection and early warning. The effect of expanding the effective detection range and improving road traffic safety performance

Problems solved by technology

However, there are two main problems with these technical means. One is that the effective working distance of the sensor is relatively short. When a moving object is detected in front and an early warning is issued, there is little time left for the driver and pas

Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings.

[0034] like figure 1 Shown is a flow chart of a wireless coordination-based method for assisting collision avoidance when a moving object crosses a road, including the following steps:

[0035] (1) Carry out continuous real-time detection on the road surface. When a moving object is detected, the motion attribute information of the moving object is calculated, and the detection warning information is synthesized according to more than one motion attribute information. The motion attribute information includes the moving object type, GPS position, motion state information and trend estimation information; the moving objects include pedestrians, vehicles and animals, etc.; the motion state information includes direction and speed, etc.;

[0036] (2) Real-time broadcast of detection and early warning information to surrounding areas through wireless means; the wireless m...

Abstract

The invention discloses a method and system for assistant collision avoidance of objects moving to pass through a road based on wireless coordination. The system comprises a moving object detection device, a pre-warning information synthesis device, a pre-warning information transmission device and a pre-warning information receiving and prompting part. According to the system, due to the moving object detection device installed beside the road, the effective detection range of moving objects on the road is expanded, meanwhile the moving objects are found through local calculation of detection information, and high practicability is achieved; the pre-warning information is broadcast in a wireless mode, the notifying range of the pre-warning information is expanded, a vehicle driver and passengers can have enough time to take corresponding measurements for road potential safety hazards probably happening, the happening probability of collision accidents is greatly reduced, and the road traffic safety property is improved.

Description

technical field [0001] The invention relates to a wireless coordination-based method and system for assisting collision avoidance when a moving object crosses a road, and belongs to the intelligent transportation technology. Background technique [0002] With the rapid development of our country's economy, the number and scale of road traffic accidents in our country are showing a rapid growth momentum. How to detect traffic safety hazards in time and give early warning, eliminate traffic safety hazards in the "infancy" state, and reduce traffic accidents caused by traffic accidents. To minimize the loss of human life and property, and to create a "smooth, efficient, safe and green" modern transportation system is a common problem faced by the transportation management department and the whole society. [0003] In road traffic accidents, a considerable part of the accidents is because the drivers and occupants of the vehicle failed to detect other moving objects that may app...
