| Notes | mine IoT; time synchronization ; SoC ; LWIP ; PTPd protocol stack According to the requirement of time synchronization of different accuracy for the existing business of underground mine, in this paper, a new design of time synchronization system based on mine Internet of Things technology is proposed. The synchro nizatiou hardware device is implemented by using STM32F407 chip system, lightweight TCP/IP stack（LWIP） and PTP daemon, and optimized by the method of noise filtering. The experimental results demonstrate that the proposed scheme is stable and reliable, and can reach nanosecond synchronization precision in back to back state.
