Study on Anti-collision Algorithm in Underground Mine Personnel Positioning System

Abstract

In order to avoid signal collision occurs when more than one electronic tag send the recognition information to the reader in underground mine personnel positioning system, an improved binary searching algorithm is proposed in this paper. The improved algorithm can reduce redundant information and searching times by using dynamic and variable querying instruction length and regressive strategy. The simulation results show that this algorithm is superior to other algorithms in searching times, searching time and throughput. It can effectively solve the anticollision problem of multi-object identification.
