摘要
测绘仪器与计算机之间的异步串行通信是现代测绘中经常遇到的问题,如何在Windows平台下实现测绘仪器与计算机之间数据通信是测量内、外业一体化的基本问题。在工作经验的基础上,详细研究和分析了利用Win32API通信函数实现串口通信编程的基本方法以及多线程技术在串口通信中的应用和特点,最后以大地型ASHTECHGPS接收机为研究对象,进行了相应的实验研究。
In modern survey, it is a common problem to implement the serial communications programs. And the way to program a serial communication program under Windows platform is a basic problem in survey data processing .On the basis of experience, we studied the method using Win API communication function to implement the serial communication programs and analyzed the characters of multi-thread technologies. Finally, taking the ASHTECH GPS for example, we studied the related technologies.
