校园电子巡更系统设计

Electronic Patrol System Design for Campus

介绍了一种基于GPS的校园电子巡更系统设计。利用GPS卫星数据接收器接收巡更人员所处的位置信息,通过单片机对有效位置信息进行存储和控制,巡更仪主要通过标准串行通信接口RS-232与上位PC机进行数据通信,在特殊情况下也可通过无线收发模块NRF905与控制中心进行数据通信。PC机在MapInfo软件平台上制作校园电子地图,并通过VB编程控制,在得到巡更仪的数据后能重现巡更人员的巡更轨迹。详细讨论了电子巡更仪的硬件电路设计,包括控制模块、GPS卫星定位模块和无线传输模块等。经实验表明,该系统性能稳定,通信效率高,功耗低,适合于保安巡更管理系统领域。

A system design of campus electronic patrol based on GPS is introduced. The GPS satellite data receiver is used to receive the information of patrol officers. The main way of communication between patrol instrument and computer is RS-232,on special occasions,wireless transceiver module NRF905 can be used. Campus map is produced using MapInfo in computer,and the map is controlled by VB programming,the patrol tracks can be reappeared after getting the information in computer. Hardware circuit’s design of the patrol instrument is discussed in detail,including the module of control,satellite location of GPS,wireless transceiver module and so on. The experiment shows that the system can work stable,communicate efficient and cost low-power as well as suitable for application in the field of security patrol management system.
