Expressway vehicle group operation risk state warning system and method

Abstract

The invention discloses an expressway vehicle group operation risk state warning system. The expressway vehicle group operation risk state warning system includes a central processing unit, a wireless communication device, a loudspeaker, an intelligent watch and a display; the wireless communication device, the loudspeaker and the display are all connected with the central processing unit through cables; the central processing unit is used for obtaining processing information according to acquired vehicle information and driver information, wherein the processing information can indicate whether vehicles are in operation risk states; the wireless communication device includes an information receiving terminal and an information transmitting terminal; the intelligent watch is used for transmitting the acquired driver information to the central processing unit; and the loudspeaker and the display are used for broadcasting and displaying. The invention also discloses an expressway vehicle group operation risk state warning method. According to the expressway vehicle group operation risk state warning system and method of the invention, vehicle groups which are in operation risk states can be warned in advance scientifically and reasonably, and the rear-end and pile-up accidents of vehicles can be avoided. The expressway vehicle group operation risk state warning system and method are of great practical significance for reducing the safety accidents of expressways and improving the safety level of the expressways.

Description

technical field [0001] The invention relates to the safety of highway vehicle operation, in particular to a warning system and method for dangerous state of vehicle group operation on expressway, which can provide scientific and reasonable early warning to vehicle groups in dangerous operation state, so as to prevent vehicle rear-end collision and serial collision accidents. Background technique [0002] With its obvious advantages such as isotropic, fully enclosed, fast, comfortable, and fuel-efficient, expressways have become an important part of my country's comprehensive transportation system. However, while expressways bring people fast and comfortable travel, there are also problems of frequent traffic accidents due to high-speed vehicle operation, fatigue driving, complex road conditions, mixed traffic flow, bad weather and many other factors, among which vehicle rear-end collision accidents are especially very. Vehicle rear-end collision accidents (two-vehicle rear-...
