Truck right-turn anti-collision early warning system and early warning method

Abstract

The invention discloses a truck right turn anti-collision early warning system for an intersection. The system comprises geomagnetism, a camera, a road side unit, an edge industrial personal computer,a vehicle side camera and a wireless communication module; a vehicle-mounted unit, an ultrasonic radar, RTK positioning equipment, a CAN bus module, an ECU, a terminal alarm device and an active braking device are installed on a truck. The invention further provides a method for carrying out intersection truck right-turn anti-collision early warning by utilizing the system. By means of the method, real-time information of people-vehicle-road-environment can be obtained, the operation states of different traffic participants at the intersection are analyzed, rapid and effective collision safety early warning is made, and the traffic safety level is improved.

Description

technical field [0001] The technical invention relates to the field of intelligent transportation, and particularly relates to an anti-collision early warning system and an early warning method for large trucks turning right at an intersection. Background technique [0002] In the urban intelligent traffic control system, the video information of road intersections is often uploaded to the traffic monitoring center platform, and the monitoring center platform processes the video and extracts traffic parameters. Due to the rapid increase in the number of video cameras and video capacity, the traffic monitoring center platform is faced with a large processing load and operating costs. The timeliness of the traffic control scheme is not high. At present, with the rapid development of vehicle-road coordination technology, the information of vehicles, roads, and other participants needs to be processed and optimized in real time, which puts forward high requirements for the time...

AI Technical Summary

Problems solved by technology

Using a single video camera to obtain the image information of the blind area of ​​the vehicle, although it can reduce the risk of right-turn collision of the truck to a certain extent, but there are also some obvious shortcomings. First, the body of the large truck is long and the blind area is large. Multiple video cameras have better monitoring effect, and the second is that the working effect of video cameras is easily affected by light (such as cloudy, rainy, foggy, night, etc.)

[0008] On the whole, in the existing early warning systems and / or methods, the road and vehicle information sources are relatively single (such as only image information, vehicle speed and position information, no non-motor vehicle / pedestrian operation information, intersection operation information)
