For this purpose, an underground personnel positioning platform was established on the wireless sensor network (WSN). Specifically, the ultra-wide band (UWB) and the time difference of arrival (TDOA) positioning algorithm were introduced briefly, in view of the underground operation environment. Then, the underground operator monitoring platform was developed based on UWB-WSN and compared it with different positioning techniques through experiments. The results show that the proposed platform achieved a high positioning accuracy and satisfied the needs of real-time monitoring of underground personnel. The research findings shed new light on the mitigation of personnel and property losses in coal mine accidents.</span>

A Posture Recognition Method Based on Indoor Positioning Technology

“…However, positioning in two-dimensional surface needs at least three arms, and positioning in three-dimensional space requires at least four non-coplanar arms. The more and longer the arms are, the higher the positioning accuracy is [27]. Due to space limitations, the length of arms cannot be infinite.…”

Analysis of Portable Mechanical Environmental Monitoring System Under Zigbee Wireless Network

“…Since the monitoring system designed in this research has mainly vibration signals, there will be a large number of signals in the actual monitoring, so the actual signal is in an unstable state. Although this shortcoming has no significant influence on the design of this research, in order to ensure the correct operation of the algorithm, the ARMA and kurtosis feature are adopted to improve the SDT compression algorithm [15].…”

A Novel Mobile Target Localization Approach for Complicate Underground Environment in Mixed LOS/NLOS Scenarios

“…Qin et al [7] studied a distributed UWB-based localization system in the underground mines, and the distributed localization algorithm based on particle swarm optimization was proposed for underground mines and implemented on the blind node. Xie et al [8] designed the UWB monitoring platform for underground localization to realize accurate and reliable positioning of the underground moving targets. Fan et al [9] presented that the UWB positioning strategy for the shear was proposed to eliminate accumulative error produced by INS and the corresponding coupling model was established.…”
