Embodiment 1
[0033] image 3 It is a preferred flowchart of a clock synchronization method in a transmission system according to an embodiment of the present invention, which includes the following steps:
[0034] S302. Calculate the sum of the carry values generated within t clock cycles of the fractional part of the main clock cycle of the system (that is, the clock cycle on the master node), where t is the total delay of clock correction;
[0035] S304, calculate and obtain the correction delay compensation value according to the sum of t, the carry value and the integer part of the system main clock cycle;
[0036] S306. Use the corrected delay compensation value to perform synchronous correction on the system slave clock (that is, the clock on the slave node).
[0037] In this embodiment, the carry value of the fractional part of the system master clock period is used as a part of the compensation value, so as to realize accurate compensation for the integer part and thus accuratel...
Embodiment 2
[0077] Figure 8 is a preferred structural diagram of a clock synchronization device in a transmission system according to an embodiment of the present invention, which includes: a computing unit 802, used to calculate the sum of the carry values generated within t clock cycles of the fractional part of the main clock cycle of the system, where , t is the total delay of clock correction; the correction delay compensation value is calculated according to the sum of the t, the carry value and the integer part of the system master clock cycle; the synchronization unit 804 is used to use the correction delay compensation value Synchronize the system slave clock.
[0078] In this embodiment, the carry value of the fractional part of the system master clock period is used as a part of the compensation value, so as to realize accurate compensation for the integer part and thus accurately compensate the fractional part of the slave clock during the calibration process.
