摘要
首先介绍了无线车辆管理调度系统中所涉及的无线通信、定位、嵌入式系统等技术,在此基础上提出了无线车辆管理调度系统的设计方案,并实现了系统的硬软件。该系统的车载终端在车辆行驶过程中可以实时地获得准确的定位和时间信息,并选择通过WLAN(无线局域网)和GPRS(通用分组无线电业务)两种方式与管理调度中心交互,实现管理调度中心对车辆实时信息的掌握并随时进行调度。
At first, this paper introduces the techniques of wireless communication, positioning and embedded system related to the wireless vehicle management and control system. Then the design scheme of this system is given and all hardware and software are developed. The in-vehicle terminal of this system can obtain the real-time accurate positioning and timing information, choose to communicate with management and control center through WLAN and GPRS, so the center can get the real-time information of vehicle, and could control the vehicle at anytime.
