Ranging System in Coalface Based on Linear Frequency Modulation Signal

Abstract:

Based on technology of linear frequency modulation, constructed a wireless communication network in accord with the standard of IEEE 802.15.4a, which being fitted for using in mine. By method of symmetric double-sided two-way ranging, implemented a precise ranging and locating system for mines and tested it in indoor environment, which is similar to the straight laneway of mine and coalface. Result data show that the system has good performance in anti-jamming and anti-multi-path effects of electromagnetic wave and can communicate in a distance of 100m in laneway. The ranging accuracy is 1.5m, which well meeting the need of locating for person and equipment in mine.
