摘要
针对目前煤矿井下人员定位系统定位精度不高、存在定位盲区等问题。本文分析了精确定位原理,研究采用基于TPSN和RBS的改进时间同步算法,设计了精确定位系统。针对改进的精确时间同步算法,在实验室进行了实验测试。通过测试验证了该方法的有效性,作为RSSI算法辅助定位功能,提高了系统的定位精度。
In view of the current personnel positioning system in coal mine,the positioning accuracy is not high,and the location blind area exists.The principle of precise positioning is analyzed in this paper.An improved time synchronization algorithm based on TPSN and RBS is studied,and an accurate positioning system is designed.In view of the improved precise time synchronization algorithm,the experiment is carried out in the laboratory.The validity of the method is verified by testing.As an auxiliary location function of RSSI algorithm,the positioning accuracy of the system is improved.
