|Title:||DATA SYNCHRONIZATION METHOD AND APPARATUS|
Provided are a data synchronization method and apparatus. The method comprises: after a fault of any one control station is recovered, performing output locking on a faulty control station in a distributed control system of a nuclear power plant, so that the faulty control station may be in a bypass state; comparing variables of the faulty control station with variables of a selected control station without a fault to determine data to be synchronized; and establishing a data transmission channel with the faulty control station, and performing data synchronization on the data to be synchronized based on the established data transmission channel. In the embodiments of the present invention, data can be reliably and accurately synchronized to a faulty control station, the operation is simple, and at the same time, the security and usability of a distributed control system are ensured.
