ABSTRACT
A precision positioning system with energy efficiency is of great necessity for guaranteeing personnel safety in underground mines. The location information of the miners' should be transmitted to the control center timely and reliably; therefore, a heterogeneous network with the backbone based on high speed Industrial Ethernet is deployed. Since the mobile wireless nodes are working in an irregular tunnel, a specific wireless propagation model cannot fit all situations. In this paper, an underground localization system is designed to enable the adaptation to kinds of harsh tunnel environments, but also to reduce the energy consumption and thus prolong the lifetime of the network. Three key techniques are developed and implemented to improve the system performance, including a step counting algorithm with accelerometers, a power control algorithm and an adaptive packets scheduling scheme. The simulation study and experimental results show the effectiveness of the proposed algorithms and the implementation.

f11-sensors-15-12358: The scenario with the maximum error.

Mentions: The maximum error happens when the miner wearing the MN changes direction immediately after TOF-P. Because the location method is based on step counting in the subsequent N periods, the system still estimates the position of the miner by historical record; therefore, it is unable to determine the real position until the next TOF-P. The maximum error that occurs in this scenario is shown in Figure 11.
