Research on mine integrated communication system
摘要
Abstract
For problems of independent operation of each system in coal mine underground and too many base stations with shortage of wireless data transmission bandwidth,a mine integrated communication system was designed by use of LTE technology.The system can realize unified accessing,loading and management of multi businesses through integrated base stations such as wireless communication,precise personnel and locomotive positioning,IP telephony,voice broadcast and so on,and connection to existing business interfaces.The test result shows that the integrated base station in the system has covering radius of 400 m with received signal strength of no less than-105 dB,switching time of wireless communication among the base stations is 21.67 ms,and the system has higher wireless communication quality.关键词
