摘　　要：研究了在掌上电脑环境下基于 Windows CE操作系统来实现农田信息快速采集的关键技术。针对典型 GPS的特点 ,提出了相应的农田信息采集的解决方案 ,并在基于 Windows CE的农田信息实时处理系统中得到了很好的应用与验证。The key technology of fast collection of field information was analyzed. According to the characteristics of typical kinds of GPS and the particularity interface communication of Windows CE, several resolve methods used for fast collection of field information were put forward. One of these methods was deeply discussed. In this method AgGPS 132 receiver was used to get both GPS signal and field information. Multithreading technology to process serial signal as quick as possible had been applied. Control flow was designed based on the particularity of Windows CE serial port communication. As a result, this resolve plan was strong enough to be used in any situation mentioned. All the research work was part of the research project of field information real-time processing system based on Windows CE. Some experiments were done to testify the applicability of these resolve plans.
