摘要
基于XT55 GPS/GSM模块,设计实现了GPS车载移动终端,该终端利用GPS获取用户当前位置和时间信息,以短消息(SMS)的形式通过GSM网络发往监控中心,同时该终端也可接收来自监控中心的控制指令,从而实现对车辆的自动报警、自动控制、自动信息查询等功能。详细介绍了终端设备的硬件设计和软件流程图。
Based on XT55 GPS/GSM, a GPS vehicular terminal system is designed and implemented. The user＇s current information of location and time is obtained by GPS, and the communication is sent to the server in the management center through GSM network. The termination can accomplish automatic warning, control, information inquire by accepting instruction from the center. The design of hardware and software flow chart of the system is introduced.
