The optimization problem of sampling synchronization efficiency in the process of power line communication is studied in this paper. An optimization strategy of calculating the synchronous position is proposed. A bit algorithm after the first piece is designed in accordance with the direct synchronization algorithm. The power line sampling is fulfilled in the process of on-chip sampling. The innovation of this paper is to use the biggest difference between high and low potentials in chip to calcu-late the displacement number in the on-chip. The sliding window was designed to calculate the on-line maximum offset. The test results show that the algorithm can increase the time efficiency by a factor of 40%.
