The Wireless Channel Characteristic Analysis of Coal Mine Rescue Robot in Unstructured Vertical Working Environment

Abstract

Coal mine rescue robot wireless communication system is the important premise to the coal mine disaster rescue work. Based on the wireless signal transmission mechanism, we research the rescue robot emergency wireless channel characteristic mode in the vertical roadway of the unstructured environment. In this environment, the signal attenuation law has been revealed. After theoretical analysis, the wireless channel change rule has been grasped in the vertical working environment. It provide the basis to rescue robot in complex environment when build a wireless communication network.
