Abstract: In recent years, as a special place for safe operation supervision, the coal yard of fossil-fuel power station has frequent safety accidents, complex scene of operation safety supervision, frequent personnel and vehicle exchanges, and severe supervision situation. This paper combines the actual situation of the coal yard production site and the rapidly developing positioning technology to achieve the construction of a coal yard operation safety protection system based on Beidou RTK and UWB technology, in order to achieve the transformation of operation safety supervision from people's air defence to technical defense, prevent the occurrence of safety accidents caused by equipment abnormalities or improper operation, and achieve monitoring in advance and early warning in case of abnormalities, so as to provide strong technical and system platform support for the later implementation of digital coal yards and smart coal yards.
Keywords: Beidou RTK positioning; UWB ultra wideband; high-precision positioning; operation safety protection; early warning

北斗RTK定位技術,也称北斗差分定位技术,利用我国自主研发的北斗卫星定位系统实现精确定位功能。定位精度可根据需要,通过选择不同精度的人员定位终端来实现。UWB定位技术,UWB(ultra wide band)是应用于无线通信领域的一种低功耗的无线电技术,采用纳秒级或亚纳秒级的脉冲实现无线通信。UWB定位采用了宽带脉冲通信技术,具备极强的抗干扰能力,使定位误差减小[1]。UWB定位技术的出现填补了高精度定位领域的空白。UWB定位技术具有对信道衰落不敏感、发射信号功率谱密度低、低截获能力、系统复杂度低、能提供厘米级的定位精度等优点。
