Description
Technical field
The utility model belongs to bend vehicle-speed monitoring technical field, is specifically related to a kind of car speed monitoring device for mountain area bend.
Background technology
Along with the raising of people's living standard, more than one, the phenomenon of car gets more and more, and this provides the chance of setting out on a journey just to the unskilled driver of some driving efficiencies.Consider Highway Current Situation domestic at present, with regard to the lineament of China Mountainous Area of North and southwestern knob, the meet accident possibility of traffic hazard of hill path, blind area is large, reason mainly driver master worker is unfamiliar with road conditions, driving efficiency is unskilled, and judge inaccurate to the information of vehicles that opposite travels, lack setup time.This just needs the system for prompting can reminding information of vehicles in blind area, driver master worker opposite, helps driver master worker to judge the information of opposite driving vehicle, driver master worker is prepared to respond in advance, the generation avoided traffic accident to a certain extent.
At present not for the system for prompting of blind area bend vehicle.Driver master worker is driving through blind area bend and judges whether opposite has car basically by observation bend convex mirror or warning of blowing a whistle, this mode limitation is large, can not judge position or the speed of opponent vehicle, delay once a side blows a whistle, the false judgment caused very likely causes traffic hazard.Data shows, and the annual traffic accidents kill of China about 100,000 people, China's automobile pollution accounts for the world 2%, and traffic accidents kill accounts for the world 20%, and significant proportion is wherein occupied to impinging upon in side.According to 10 large high-risk sections of national publication, the traffic hazard main Types at 5 places is had to be that side is to shock.Side is bend crossing, blind area place to the district occurred frequently of clashing into.
Domestic vehicle monitoring system is roughly divided into four classes: video camera tracking imaging, foil gauge pressure detection, portable ultrasonic ripple test the speed and radar tracking.Camera location imaging cost is medium, be used for the smooth main road of broad view, for detecting the vehicle of hypervelocity, this technological merit is can recording information of vehicles at any time, the form of expression understands, can be used as the voucher of accident dispute, at traffic lights place, high speed crossing, the application of the place such as forthright be comparatively extensive.Some cities arrange traffic control center, unify to control and monitoring to all video cameras.The cost of foil gauge pressure detection and radar tracking system is higher, studies substantially complete, but application is not popularized.Portable ultrasonic ripple tests the speed and is used by traffic-police in a large number, and on satisfying the need in roadside, the speed of vehicle detects, and Timeliness coverage over-speed vehicles, prevents in time.This equipment is simply portable, easy to operate, but limitation records information to need artificial process, can not realize robotization completely.
