基于北斗差分定位技术的站场数字化系统

提出一种基于北斗差分定位技术的站场数字化系统。使用实时动态（RTK）载波相位差分定位技术获取站场元素的精准位置信息，通过无线的方式将位置信息传输到上位机；上位机对位置信息进行处理，调用站场图完成位置信息与物理元素的匹配，实现站场数字化，最后将完成位置信息匹配的站场图保存起来。经测试，系统定位精度稳定在10 cm以内。在Windows平台下使用C++builder开发出上位机软件，嵌入式软件使用C语言在KEIL平台下开发。该系统具有定位准确、使用方便、扩展性强和可靠性高等特点，为列车安全防护、调度、监控等作业提供可靠保障。

Station yard digitization system based on Beidou differential positoning technology

This paper proposed a station yard digitization system based on Beidou System positioning technology. An accurate location information was obtained by using RTK differential positioning technique, transmitted to host computer by wireless mode. The upper computer processed the location information, call the station yard map to match the location information with the physical element, and implement the station yard digitization, store the station yard map of matching the location information. After testing, the positioning accuracy of the system was within 10 cm. C++ builder was used to develop upper computer software under Windows platform. C language was used to develop embedded software under KEIL platform. The system has the characteristics of accurate positioning, convenient operation, high expansibility and high reliability, provides reliable guarantee for train safety protection, dispatching and monitoring.
