Vehicle Monitor Terminal System Based On GPS/GPRS

AS China's economic development? more and more cars in the world, andmore and more attention will be paid in road traffic. Many events occured?forexample,the car be stealed and robbed. Which had bring bad imparience onsociety,That case the ease pressure on urban traffic. The paper introduces GPSminitoring.It real-timely transmission the owners vehicle dynamic location? statusmessage and speed informations, which they could achieve real-time vehicle position.It plays an important role in vehicle safety and life safety. Moreover, Located basedservice is the big challenge of mobile communication market in society.it also cantransmission vehicle location information to the monitoring center in time,which thebetter safety has been achieved.This paper describes the design of vehicle monitoring terminal system.First,The technology of the global satellite positioning system positioning wasintroduced in detail, and its working principle is analyzed. After several wireless datatransmission are compared. The GPRS General Packet Radio manner was the bestchoices as the data for the selected transmission mode, vehicle terminal S3C6410isused in the control unit. Combined with the GPS module of the SIRF StarIII toreceive data on WinCE, the end-to-vehicle data is transferred to monitoring centerthrough the serial port GTM900-C model GPRS module, ultimately. The main subjectof research by the following chapters:1. The background research status vehicle monitoring terminal, purpose andmeaning, and topics has been described2. The overall framework of the system hardware and specific hardware interfacehad been designed3. The overall system design software framework and specific functional modulehad been designed4. Create constraints restricting road information Kalman filter model for GPSreceiver receives data for processing.5. The data transfer protocol is researched...
