Intelligent anti-collision early warning system

Abstract

The invention relates to an intelligent anti-collision early warning system. A road test intelligent traffic information detection technology is used to detect the speed and the distance of a runningvehicle close to a construction section in real time. A one-shot multi-receiving radar antenna is used to realize a multi-target tracking three-dimensional space microwave detection technology. One radar can cover a space within the 200 meters of multiple lanes, and the radar is installed on a road side without destroying a road and interrupting traffic. All-weather automatic detection is performed and warning information is actively issued, and the system is not influenced by weather, light, and climate changes. The abnormal driving conditions of vehicles behind construction personnel can beprompted in real time, such overspeed, retrograde moving, lane changing, illegal parking and the like, and accidents are reduced. At the same time, the expansion functions of traffic flow and averagespeed statistics and the like are performed, a traditional roadside microwave vehicle detector is replaced, an LED variable information board can be connected, the system can be used to actively warndanger, and a set of equipment has multiple purposes, and cost is saved.

Description

technical field [0001] The invention belongs to the technical field of traffic operation control and relates to an intelligent anti-collision early warning system. Background technique [0002] In recent years, with the continuous development of my country's economy, the construction of expressways has also advanced by leaps and bounds. But at the same time, traffic accidents due to expressway maintenance have also increased significantly. [0003] The common causes of accidents caused by expressway maintenance mainly include the following points: (1) The construction signs are not standardized: the setting area is too small, too close, and the construction signs are incomplete, old, and unclear. (2) Factors of the driver: Since the expressway is fully closed and the overpass is in good condition, the driver does not need to take too many measures when the vehicle is driving, resulting in a decrease in the vigilance of the driver. When driving at high speed, the dynamic vi...

Problems solved by technology

[0003] The common causes of accidents caused by expressway maintenance mainly include the following points: (1) The construction signs are not standardized: the setting area is too small, too close, the construction signs are incomplete, old, unclear, etc.

(2) Factors of the driver: Since the expressway is fully closed, the overpass is good, and the road conditions are good, the driver does not need to take too many measures when the vehicle is driving, resulting in a decrease in the vigilance of the driver

When driving at high speed, the dynamic vision of the driver is obviously reduced, and the effective field of view is narrowed, and the necessary information may be found too late or not at all, resulting in an increased possibility of misjudgment during driving, or panic about sudden dangers, and the handling measures Mistakes

[0004] The warning systems that are commonly installed mainly use concave-convex mirrors and traffic warning signs, which are passive safety facilities and cannot actively warn of danger; they are greatly affected by external ambient light and cannot fully play a warning role.
