Utilizing the vehicle navigating and positioning data and the status messages of vehicle, the vehicle recorder system based on GPS and GPRS can display the position and the status of the vehicle, while the operator can also send a lot of remote-controlling commands to the vehicle. These messages are mainly sent and received by the digital channel provided by GPRS.First of all the paper describes the important significance of the vehicle recorder system on the management of traffic and vehicle.Through hard work of study on GPS technique and the ARM embedded hardware platform, and comparing the service, accessing mode of GPRS with the other wireless transporting mode, this paper provides a vehicle recorder system solution by utilizing the GPRS SMS (short message service) to transport the vehicle messages, monitoring center messages.Then this paper elaborates software and hardware design of the vehicle recorder system. System includes the GPS data collection, GPRS part, display and communications with PC etc.it provides the orientation and monitoring of the vehicle.This paper provides a feasible vehicle recorder system solution. |
