| 摘 要： | 针对铁路安全隐患问题，提出将第三代北斗卫星导航系统（简称：北斗三代）高精度定位技术引入铁路监测预警，设计了基于北斗三代的铁路监测预警系统，该系统利用北斗高精度定位的原理实现位移数据高精度监测，同时具备实时传输和即时预警等功能。实践证明，该系统相对于基于GPS的监测预警系统具有明显优势，可见的卫星个数显著增加，水平精度提高20%以上，高程精度提高50%以上。同时通过不同基线长度下监测性能的对比，为合理布设基准站提供参考。

| Abstract: | Aiming at the hidden danger of railway safety, this paper introduced the third generation Beidou satellite navigation system (Beidou third generation for short) high-precision positioning technology into railway monitoring and early warning, designed the railway monitoring and early warning system based on Beidou third Generation. The system used the principle of Beidou high-precision positioning to implement high-precision monitoring of displacement data, and had real-time transmission and instant warning functions. Practice has proved that the system has obvious advantages over the GPS based monitoring and early warning system, with a significant increase in the number of visible satellites, an increase in horizontal accuracy of more than 20%, and an increase in elevation accuracy of more than 50%. Through the comparison of monitoring performance under different baseline lengths, it provides a reference for the reasonable deployment of reference stations. |
