基于GPRS的汽车状态与故障监控终端

为了实现汽车生产销售服务中心对汽车状态的跟踪, 并对出现故障的汽车进行远程控制, 将嵌入式系统与GPRS（General Packet Radio Service）无线通信技术相结合, 实现了新型汽车状态与故障监控终端的设计。终端能在汽车行驶一定里程数以及在出现故障特征时利用GPRS网络信号以特定的数据帧格式将汽车状态与故障信息发送给中心, 中心通过与标准参数对比的方式对大量汽车状态数据进行分析, 解决汽车的安全隐患并远程控制出现故障的汽车。同时, 分析了汽车运动对数据传输可靠性的影响, 并通过实验测试证明了该系统的有效性。

Automobile State and Fault Monitoring Terminal Based on GPRS

To realize car production and sales service center monitor cars status and remote control car which appears failure characteristics. In this paper,combining embedded system and GPRS（General Packet Radio Service） wireless communication technology, we realize the design of new cars state and fault monitoring terminal. The terminal can send the vehicle state and fault information in a particular data frame format to center using GPRS network signalwhen the car runs fixed distance and appears failure characteristics, the center analyzes mass state data through comparing with the standard parameters, solves the safety hidden trouble and improves the design and construction of the product and remote control the car which appears failure characteristics. At the same time, this paper analyzes the effect of vehicle motion on data communication, and effectiveness of this system have been proved by experimental test.
