Abstract
The invention discloses a highway real-time speed limiting system in hazy weather. The system has the functions of automatically adjusting the current highest driving speed suitable for speed-limited driving of a vehicle according to the visibility index of haze and the slip degree of a road section, and speed limiting is automatically relieved and highest driving speed is automatically restored when the weather turns fine. The driving speed of the vehicle is determined by obtaining a wireless radio frequency speed-limiting signal of each road section on a highway, accordingly the vehicle sends out voice, light and digital prompts corresponding to the speed-limiting driving speed of the current road section, the visibility index and road slip situations, and an accelerator system of a vehicle execution mechanism is automatically controlled to control the driving speed of the vehicle. However, normal forced speed limiting can be automatically carried out on the vehicle at the road sections where accidents often happen, and accordingly traffic accidents caused by overspeed driving on hazy, rainy and snowy days are completely avoided.
Description
Technical field
The present invention relates to a kind of highway speed limiting system, be specifically related to a kind of highway haze weather real-time speed limit system.
Background technology
Highway is the main body of highway in China transport, it promote economic development and social progress in the middle of play huge impetus.Developing rapidly of highway and car industry but brought ladder of management and traffic aid to relatively lag behind in recent years, traffic hazard is constantly soaring, and even hundred car collision phenomenons are of common occurrence, trace it to its cause to be exactly: due to the wet and slippery and indivedual drivers in the low visibility of haze weather and road surface drive over the speed limit with idea of leaving things to chance.Cause huge loss therefore to people's life and property, but also can affect the stable of society.
Existing technology relies on traffic policeman's patrol monitoring law enforcement on highway exactly, and utilizes monitoring camera and Microwave Velocity instrument and electronic display to supervise prompting driver and abide by chapter driving.But in the weather environment of haze and sleet, concerning indivedual minority drivers, drive over the speed limit and stick to one's old way of doing things that is just helpless.
Summary of the invention
The object of this invention is to provide a kind of highway haze weather real-time speed limit system, can effectively solve the problem of highway automatic speed-limiting in the time of the low visibility of haze sleety weather.
A kind of highway haze weather real-time speed limit system, it is characterized in that: comprise be arranged on expressway access and outlet, expressway access removes speed limit less radio-frequency sending module 3 and removes speed limit less radio-frequency sending module 4 and 6 wireless connections of onboard wireless Receiver Module with expressway exit, removes speed limit to thus the automobile that rolls expressway exit away from.
Described roadside less radio-frequency sending module 5 is connected and 6 wireless connections of onboard wireless Receiver Module with roadside haze speed detection module 1 respectively, described roadside haze speed detection module 1 is to regulate and be applicable to the current maximum travel speed that automobile speed limit travels according to the visibility index of haze, automatic detection, can automatically remove speed limit to vehicle and can reach maximum travel speed in the time that meteorological condition takes a turn for the better.
Described roadside less radio-frequency sending module 5 is connected with roadside sleet speed detection module 2 respectively, and 6 wireless connections of onboard wireless Receiver Module.Described roadside sleet speed detection module 2 can the current section of Real-time Collection the wet and slippery extent index in road surface, can automatically adjust and be applicable to the current Maximum speed limit travel speed that automobile speed limit travels, in the time that pavement conditions takes a turn for the better, can automatically terminate speed limit and automatically restore to maximum travel speed.
Described cab signal processing module 7 is connected with vehicular speeds prompting device 8, onboard wireless Receiver Module 6, vehicular speeds topworks 9 respectively.The travel speed of automobile is that basis is obtained on highway, the signal order of the roadside less radio-frequency sending module 5 in each section determines, vehicular speeds prompting device 8 can send corresponding voice, light and the digital prompt such as current, speed limit travel speed and visibility index, the wet and slippery situation in road surface thus, and then automatically controls throttle system vehicle, vehicular speeds topworks 9, controls the travel speed of vehicle.
Described a kind of highway haze weather real-time speed limit system, it is characterized in that: roadside haze speed detection module 1 and roadside sleet speed detection module 2, can be in the time that meteorological condition and pavement conditions take a turn for the better, automatically vehicle is removed to speed limit and reach maximum travel speed, but can be automatically in accident-prone road section to vehicle carry out normalization pressure speed limit, can be chosen in 60-120 kilometer/hour of following speed, set voluntarily by freeway traffic regulation department according to actual conditions.
The present invention compared with prior art has the following advantages:
By being arranged on the roadside haze speed detection module 1 and roadside sleet speed detection module 2 and roadside less radio-frequency sending module 5 on highway, energy real-time detection generates the current speed-limiting messages in each section on highway, realize automatic speed-limiting, thereby thoroughly avoid the phenomenon of travelling because of haze weather and sleety weather high way super speed to occur, improved the traffic capacity of highway and efficiency of operation and avoided the generation of traffic hazard.The present invention is practical, and intelligent degree is high, can extensively on various highways, use.
