【摘要】 为了方便导盲仪定位信息的导出,更好地实现远程定位信息的监控,设计了一种基于NMEA-0183协议的导盲仪GPS信息采集和解析系统。该系统首先通过U-Center软件实现串口通信采集和接收GPS定位信息,并借助外部软件MATLAB对定位数据进行解析从而获取导盲仪位置关键信息,最后通过C#语言编写的WinForm窗体程序实现了标点定位和运动轨迹可视化显示。使用导盲仪进行试验验证结果表明,该系统可有效地采集和解析基于NMEA-0183协议的导盲仪GPS数据,并能够方便地显示出导盲仪GPS定位信息,可广泛应用于导盲仪定位及其运动轨迹分析问题中。更多还原

【Abstract】 In order to facilitate the export of the position information of the blind guide and to better realize the monitoring of the remote position information,a GPS information acquisition and analysis system of the blind guide based on NMEA-0183 protocol is designed in this paper.The system firstly collects and receives GPS positioning information through serial port communication with U-Center software,then parses positioning data with external software MATLAB to obtain key position information of blind guide instrument,and finally realizes punctuation positioning and visual display of motion trajectory through WinForm program written in C# language.The results show that the system can effectively collect and analyze the GPS data of the blind guide instrument based on NMEA-0183 protocol.更多还原
