SDS—TWR技术在煤矿人员定位系统中的应用
Application of SDS-TWR technology in coal mine personnel positioning system
-
摘要: 针对目前煤矿人员定位系统大多只能掌握井下人员所在区域、不具备精确定位功能的问题,介绍了一种对称双边两路测距(SDS-TWR)技术的原理,并将其应用到煤矿人员定位系统中。测试结果表明,基于SDS-TWR技术的煤矿人员定位系统测距误差在2 m以内,能够满足井下人员定位的精度要求。Abstract: For problem that most coal mine personnel positioning system can only get area of underground personnel without accurate positioning function, principle of SDS-TWR technology was introduced and the technology was applied into coal mine personnel positioning system. The test results show that ranging error of coal mine personnel positioning system based on SDS-TWR technology is less than 2 m, which can meet accuracy requirement of underground personnel positioning.
