摘要
介绍了一种基于GPS和GPRS的车载定位终端系统设计。利用GPS卫星数据接收器接收车辆所处的位置信息,通过单片机对车辆位置的有效信息进行存储和控制,当车载终端接收到控制中心的指令后,通过GPRS网络传输车辆的位置信息。详细讨论了车载终端的硬件电路设计,包括控制模块、GPS卫星定位模块和GPRS无线传输模块等。实验证明,该系统性能稳定,通信效率高,功耗低,适用于车载定位监控领域。
A system design of vehicle location terminal based on GPS and GPRS is introduced.Useing GPS satellite data receiver to receive vehicle location information, throughing single-chip computer to store and control effective information of vehicle. When the vehicle terminal receiving instructions from control center,the vehicle location information is transmitted through GPRS. Hardware circuits design of the vehicle terminal is discussed in detail, including the module of control, satellite location of GPS,wireless transmission of GPRS and so on. The experiment shows that the system can work stably, communicate efficiently and cost low-power, and is suitable for application in the field of vehicle location monitoring.
