摘要
讨论了连接PDA与GPS的测量软件开发方法 ,WindowsCE开发规则 ,线程开发方法 ,串行口的通信开发方法 ;讨论了GPSWGS 84坐标同地方坐标的转换方法 ,GPS接收、发送数据的命令集 ;根据以上开发技术与基本理论在PDA中实现了通过串行口控制GPS的测绘软件开发 。
In this paper, the surveying software development method of the communication between GPS and PDA, the development mode based on Windows CE, the threads development methods, development method of the communication on COM port are studied.The transformation method between WGS-84 coordinates of GPS and local coordinates, the command set of GPS receiving and sending data are discussed.Based on the development technologies and these basic theories,the surveying software development of controlling GPS on PDA is accomplished, with which the reference mode of controlling mobile device through PDA is provided.
