基于时间测距的矿井人员定位方法研究
Research on mine personnel positioning method based on time range
摘要
Abstract
Four kinds of mine personnel positioning methods based on time range were researched,namely TOA,TWR,SDS-TWR and TDOA positioning methods,they are less influenced by roadway environment and suitable for mine personnel precise positioning.TOA positioning method requires time of transmitting device and receiving device must be strictly and accurately synchronized,clock accuracy requirement of transmitting device and receiving device is very high with synchronous calibration,so its positioning card and substation cost high.TWR positioning method does not need to strictly synchronize in clock of signal transmitting device and receiving device,so complexity and cost of its positioning system is reduced,but its positioning precision is affected by clock error of positioning card and substations,positioning card and substation cost high.SDS-TWR positioning method does not need to strictly synchronize in clock of signal transmitting device and receiving device,so influence of clock error of its positioning substation and card on positioning precision is reduced,but its positioning precision is affected by clock error of positioning card and substations,positioning card and substation cost high.TDOA positioning method requires time between positioning substations must be strictly and accurately synchronized,and clock accuracy requirement of positioning substations is very high with synchronous calibration,positioning card cost lower and positioning substation cost higher.关键词
