Research And Implementation Of Mine Communicator Equipment Based On Terrane Communication

Rock as a specoal kind of communication wireless communications technology, isa high conductivity of clay rocks as a medium for communication.Based on the rock ofmine communication machine based on communication coal mine underground cabletransmission can’t touch or wireless signal can’t transfer the voice and datacommunications, it has the characteristics such as protable, low power consumption,especially suitable for underground emergency and emergency communications.Mine isalso reserved for communication equipment and coal shaft sensor interface, senornetworks can be connected undergrand, and further integration into the undergroundtransport netwoek.The paper introduces a kind of based on software radio, vlf-em low bit rate ofspread spectrum communication technology, with M element method DS spreadspectrum modulation and RS code channel coding technology, the receiver usescoherent reception dispreading. Through computer simulation, get the systemconfiguration parameters in the FPGA programming implementation, and hardwareplatform in verified. Test results show the mine communication machine voice timbre,data transmission right.
