摘要
针对户外定位跟踪等基于位置的信息服务应用领域的实际需求,文中在嵌入式人机交互HMI移动设备上实现了自定位系统。用户所在位置的信息由GPS模块获取,GPS模块与HMI设备之间通过串口进行通讯,信息遵循NMEA-0183协议,经过解析处理后的信息在HMI设备上显示出来,同时利用经纬度信息动态构建Google静态地图API网址参数,通过Internet获取所在位置的地图信息,最终将地图信息显示在HMI设备上实现自定位。结果表明,该方法简单可行,能直接应用于定位与跟踪类的应用软件开发。
To solve the actual demand of the outdoor location tracking applications fields, the self-localization system is achieved on the embedded man-machine HMI mobile device. User location information is obtained from the GPS module. The GPS module and HMI communicate through serial port. Information follows the NMEA-0183 agreement. The processed information is displayed in the HMI, while Google static map API URL parameters are constructed dynamically by the latitude and longitude information, the location map in- formation is obtained by Internet. At last it is displayed in the HMI mobile terminal to realize the self-localization. The results show that, the method is simple and practical, it can be directly applied to the applications of software development about positioning and tracking fields.
