基于设计的GPS接口通信协议的语音呼叫系统方案

摘要

针对混凝土搅拌车企业里出现混凝土搅拌车工作时车辆严重偏离轨迹、司机偷油偷料及车辆严重超速等情况下,电话语音呼叫系统不能及时语音自动拨号通知客户,提出一种将语音呼叫系统与车辆定位监控系统的业务服务器连接进行数据交互的语音呼叫系统解决方案.该系统首先进行GPS接口通信协议的设计,然后利用此协议进行语音呼叫系统的各功能模块的设计,最后进行系统功能测试.实际结果表明,当监控到车辆出现严重异常时,语音呼叫系统能够第一时间自动拨号给车辆企业告知车辆信息,通话过程可以实时监控车辆位置信息,使企业更好地管理车辆、提高效率、节约成本,防止不必要的损失.%When the concrete mixer truck works in the concrete mixer business, the vehicle is seriously deviated from the track, the driver steals the oil, and the vehicle is seriously overdriven, the telephone voice call system can''t promptly automatic dialing to notify customers.A voice calling system scheme is proposed which is connected with the service server of the vehicle positioning and monitoring system for data exchange.The system firstly designs the communication protocol of GPS interface, then uses this protocol to design the function module of the voice calling system, and finally carries on the system function test.The actual results show that the voice calling system can timely inform business about the vehicle information by autodial as soon as monitoring to the vehicle abnormality.Call process can be real-time monitoring of vehicle location information, enabling enterprises to better manage vehicles, improve efficiency, save costs and prevent unnecessary losses.
