摘  要：
针对目前村镇建设在用地再开发的传统监测方法中,存在监测终端没有定位信息或者定位精度十分有限、定位信息不能及时回传到后台监控系统等问题,本文研究一种基于CORS(Continuous Operational Reference System,连续运行卫星定位服务综合系统)的高精度差分定位终端。该终端通过主控芯片stm32f103zet6来驱动GPS定位OEM板,获取粗略的单机状态下的定位信息,利用GPRS网络将其上传到CORS中心,之后接收CORS中心回传的差分信息,最终输出高精度定位信息;最后利用GPRS网络,将定位信息回传到指定的IP地址上,以便后续使用和研究。该装置采用C语言编程,根据实际应用编写了差分信号传输协议和应用程序,实现了高精度差分定位信息的获取并且将定位信息回传到后台监控系统,满足了村镇建设用地再开发实时监测终端的定位可靠性和精确性,为村镇建设用地再开发现场实时监测提供了一种简便的定位手段。

摘  要：
In order to solve the problems that exist in the ?realm of the village and town construction land redevelopment monitoring methods at present such as low efficiency, lack of positioning information or low precision of positioning accuracy, and that the positioning information being not able to reach the monitoring background system in time, etc. the paper gives a brief introduction to a high precision positioning access device used for village and town construction land redevelopment based on CORS(Continuous Operational Reference System).The high-precision positioning access device drives GPS-OEM broad by main control chip stm32f103zet6 to seize the position information on the coarse state of single machines, uploads the information to the center of CORS by GPRS, receives the differential signal from the center of CORS and outputs high-precision position information. Meanwhile, the position information is posted back to specified IP address for continuous usage and study by GPRS.?The device which adopts C language programming, writes differential signal transport protocol and application program according to practical application and gets high-precision position information and sends it to monitoring background system. It ensures reliability and accuracy of village and town construction land redevelopment positioning real-time monitoring terminal and provides a convenient positioning method used in village and town construction land redevelopment positioning real-time monitoring.
