This paper is based on Orthogonal Frequency Division Multiplexing(OFDM)technology, which is the core of the coal mine underground medium voltage electric bridge set technology. And to enhance the real-time and accuracy of communica-tion, it puts forward the Partial Transimt Sequence(PTS)algorithm based on real numeric genetic algorithm and the timing chro-nization algorithm based on SC algorithm. It completes the preliminary design of medium voltage electric bridge set hardware system. The simulation results show that compared with other optimization algorithm, the convergence speed is faster, the tim-ing estimation precision is higher, the system performance has been improved obviously.
