Robust localization system using Visible Light Communication technology for underground mines

Abstract : Advances in electronics and communications technology have created new safety regulations that must be applied in order to operate underground mines safely and optimally. In 2006, the U.S. government updated its safety policies and adopted PUBLIC LAW109-236. As a result, monitoring of personnel inside underground tunnels is now mandatory for mining operations. This new regulation establishes that the current location, or immediately prior to the accident, of all underground personnel must be delivered to an external monitoring station. Despite recent advances in tracking and positioning systems for indoor environments, underground mines provide a unique environment that places different constraints on current technologies. In recent years, Visible Light Communications (VLC) has attracted the attention of researchers, mainly due to recent advances in the manufacture of Light Emitting Diodes. The rapid development of VLC systems has encouraged researchers to propose positioning solutions based on this technology. Visible light positioning (VLP) has several advantages over traditional positioning methods. Most VLP methods have been evaluated in scenarios where a dense and well-deployed VLC network exists. Underground mines, on the other hand, are a dynamic and inherently hazardous environment and most of the assumptions made for traditional indoor environments are not met. The feasibility of using a VLP system under such conditions and capable of meeting positioning requirements remains an open question. In order to answer this question, we study the constraints, limitations and requirements of current positioning technologies when applied in an underground mining environment in order to determine the best architecture to guarantee the positioning service while meeting the location requirements. Our proposal uses the positioning limitations, capabilities and requirements to design a low-cost, large-scale positioning architecture. Using this design, we have developed a real-world platform to evaluate the performance of visible light positioning methods. Finally, a new robust positioning method is presented. Unlike most existing methods in the literature, our proposal is not directly derived from RF-based methods. The robustness of our method to multiple perturbations (errors in the measurement of height, tilt angles, and multipath propagation due to light reflections from walls) has been tested.
