Vehicle overspeed real-time analyzing system and vehicle overspeed real-time analyzing method

Abstract

The invention discloses a vehicle overspeed real-time analyzing system which comprises a track acquisition device and an overspeed analyzing server, wherein the track acquisition device is connected with the overspeed analyzing server through a wireless network. The track acquisition device comprises the components of a positioning module which acquires latitude and longitude data and vehicle speed of the vehicle, a storage unit which stores the latitude and longitude data and vehicle speed of the vehicle at different time points through a data sheet, and an online communication module which uploads the data sheet stored in the storage unit. The overspeed analyzing server comprises the components of a map database which stores digital map data that comprise a speed limit value; an overspeed analyzing unit which performs matching on the acquired latitude and longitude data and road data in the map database, acquiring a matched rod of the latitude and longitude, comparing the speed limit value of the matched rod with the vehicle speed, determining overspeed when the vehicle speed is higher than the speed limit value, and analyzing overspeed information; and a data communication module which is used for communicating with the online communication module and acquiring the data sheet stored in the storage unit. The vehicle overspeed real-time analyzing system has advantages of high real-time performance, low cost and high data application efficiency.

Description

technical field [0001] The invention belongs to the technical field of speed monitoring, in particular to a real-time analysis system for vehicle overspeed. Background technique [0002] At present, the judgment of vehicle speeding mainly uses the road speed radar to measure and record the time and speed of the vehicle passing the radar. After comparing with the speed limit value of the road in the background, the location and time of the vehicle speeding are obtained. There are mainly the following disadvantages: [0003] 1) Only when the car passes near the road speed radar, can it be judged whether the car is speeding, so that the monitoring of the speeding behavior of the car is intermittent; [0004] 2) The use of road test equipment and background data needs to go through the traffic control department, and the use of other units is costly and delayed. [0005] 3) The laying investment cost of road speed measuring radar is relatively high. [0006] There are also re...

Problems solved by technology

[0003] 1) Only when the car passes near the road speed radar, can it be judged whether the car is speeding, so that the monitoring of the speeding behavior of the car is intermittent;

[0004] 2) The use of road test equipment and background data needs to pass through the traffic control department, and the use of other units is costly and delayed

[0005] 3) The cost of laying road speed radar is relatively high

The function of the system is complex, and the vehicle module can be used to alarm, and the method of vehicle positioning is relatively complicated, which may easily cause slow processing speed, low efficiency, poor real-time performance, etc.
