The invention provides a clock synchronization method, a clock synchronization device and terminal equipment. The clock synchronization method comprises the following steps: acquiring optical fiber transmission delay of a first signal; acquiring signal processing delay of signal processing of a field programmable gate array (FPGA) in the terminal equipment; determining time delay between the first terminal device and the second terminal device according to the optical fiber transmission delay and the signal processing delay; and sending the time delay to the second terminal equipment, so that the second terminal equipment performs time compensation according to the time delay, and clock synchronization between the second terminal equipment and the first terminal equipment is realized. According to the scheme, in the clock synchronization process, the optical fiber transmission delay of the first signal in the process of sending the first signal from the first terminal device to the second terminal device is considered, the signal processing delay of signal processing performed by the FPGA in the terminal device is also considered, and the time delay of clock synchronization is obtained according to the optical fiber transmission delay and the signal processing delay. The clock synchronization precision can be improved.
