【摘要】 车载定位监控系统共有两个主要模块:车载端和监控终端。车载端由BBB控制板和SIM908模块构成,工作过程为BBB主控板开启SIM908GPS功能,同远程监控终端建立数据链接,获取GPS地理位置数据,然后将所获得的数据解析打包,并通过GPRS网络将数据发送到远程监控终端。远程监控终端由X86PC机构成,首先监控端建立基于外网IP地址的服务器,然后监听连接请求,获得请求后建立通信连接、接收数据,并对数据进行解析,最后将车辆定位信息在Google和Baidu在线地图上进行标记显示。更多还原

【Abstract】 Vehicle positioning and monitoring system consists of two main modules,the vehicle terminal and the monitoring terminal.The vehicle terminal includes BBB control board and SIM908 module.The BBB board opens the SIM908 GPS function,establishes data link with the remote monitoring terminal,gets GPS location data,then analyses and packs the GPS data,at last sends the Packed data to the remote monitoring terminal through the GPRS network.The remote monitoring terminal uses X86 PC.First the monitoring terminal establishes server based on external network IP address,and then listens for a connection request.After obtaining the request,the monitoring terminal will establish communication connection,and receive GPS data,then analyze.Finally the vehicle location information is displayed in the Google and Baidu online maps.更多还原
