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.
