TPS time synchronization improving algorithm based on IEEE1588 synchronization mechanism

The invention discloses a TPS time synchronization improving algorithm based on an IEEE1588 synchronization mechanism, and belongs to the technical field of accurate clock synchronization. The TPS time synchronization improving algorithm based the IEEE1588 synchronization mechanism includes following steps: step 1, statistically calculating clock frequency deviation, and completing frequency synchronization; step 2, statistically calculating synchronous time deviation, communication time delay and the minimum number of messages needed for achieving designated accurate time synchronization, and completing initial time synchronization based on symmetry time delay; step 3, completing the accurate time synchronization based on the symmetry time delay by using the minimum message number, building fuzzy control which uses transmission error and transmission error change rate as input in the subsequent process, and performing on-line time deviation and frequency change adjustment.
