Vehicle section speed limit method based on vehicle wireless terminal

Abstract

The invention discloses a vehicle subsection speed-limiting method based on a vehicle-mounted wireless terminal. A vehicle monitoring platform issues characteristic parameters of road sections to the vehicle-mounted wireless terminal, and the vehicle-mounted wireless terminal receives and stores the characteristic parameters. When a vehicle runs, the real-time position of the vehicle is positioned through the vehicle-mounted wireless terminal, the characteristic parameters in a storage device are called for being compared with real-time position information of the vehicle, and the road section where the vehicle-mounted wireless terminal is located is judged. The current speed of the vehicle is compared with the speed-limiting value of the road section where the vehicle is located, whether the vehicle is overspeed or not is judged, and overspeed information and position information of the vehicle-mounted wireless terminal are reported to the vehicle monitoring platform if the vehicle is overspeed. According to the vehicle subsection speed-limiting method, the characteristic parameters of the road sections are issued to the vehicle-mounted wireless terminal in advance to be stored, when the vehicle runs, only the stored characteristic parameters are required to be directly called for being compared with the real-time longitude, the real-time latitude and the real-time speed of the vehicle, vehicle overspeed monitoring on different road sections at any time can be accordingly achieved, influences of network signals are avoided, and accurate monitoring on the different road sections can be achieved.

Description

technical field [0001] The invention relates to a vehicle section speed limit method based on a vehicle-mounted wireless terminal. Background technique [0002] With the increase of newly built and revised expressways, national highways and international highways in recent years, the traffic pressure has been greatly relieved, the speed of vehicle circulation has been accelerated, and the carrying capacity has been improved. However, the overall improvement of highway conditions has brought another problem, the problem of vehicle speeding. A large number of facts have proved that speeding on expressways is one of the main reasons for major traffic accidents, and the resulting casualties and property losses are even more serious. Shocking. The vehicle speeding supervision mechanism can deter drivers who violate the rules and speeding to a certain extent. By means of economic penalties plus penalty points and revocation of driver's licenses, drivers are forced to abide by tra...

Problems solved by technology

This solution can achieve more accurate monitoring for multiple road sections, but for road sections with poor network signals, because the vehicle cannot upload real-time vehicle latitude and longitude and speed, the vehicle monitoring platform cannot immediately determine whether the vehicle is in a speeding state, and cannot count the vehicle's speed speeding information
