A new safety production monitoring schemes and emergency rescue communication system based on LTE technology for coal mine is introduced, which mainly responsibility is conveying video data of disaster scene and ensuring the two-way communication of mobile terminal and emergency communication car. The schemes include to use of TDD full-duplex mode to make uplink configuration as much time slot resources as possible, SC–FDMA for uplink multi-access technologies and OFDMA for Downlink. Considering the terminal ability, MIMO antennas of uplink and downlink antennas is available. At the same time we adopt HARQ and adaptive modulation coding technology to improve reliability and transmission efficiency. The Performances of link level are simulated aiming at transmitting schemes. Respectively use QPSK, 16QAM, 64QAM three methods of modulation, the simulation results show that the LTE technology can satisfy the requirements of data rate, BER and delay for wireless communication under emergency environment in coal mine.
Key words: Coal mine, emergency rescue, Long Term Evolution (LTE), safety production monitoring, , ,
