The invention discloses a production process full-period intelligent workshop system based on a digital twinning technology and a solving method. The system comprises a design planning module and a virtual-real synchronization module. The design planning module is used for building virtual components required by the digital twin of the automatic workshop in the virtual component design module, carrying out process design according to actual production requirements, arranging an automatic production line, and verifying a production line planning effect and a control program. The virtual-real synchronization module builds a real production line after verification, collects the operation data of the real production line, transmits the operation data to the data management and storage module, completes the synchronization between the real production line data and the digital twin data, and displays the virtual-real synchronization condition and the operation data, and finally guides the actual production by using the data processing result of the digital twin. The system and method run through the full life cycle of the production line, and production accidents and economic losses caused by design defects can be avoided; the simulation credibility is improved; and feedback control is performed on a real production line, so that major safety accidents and property loss can be effectively avoided.

The embodiment of the invention discloses a method for correcting local time, comprising the following steps: receiving the second clock signals sent by at least three clock sources through a clock server, obtaining the difference of the rising edge arrival time of every two second clock signals, judging whether the difference between the rising edge arrival time of one second clock signal and the rising edge arrival time of other second clock signals is larger than and equal to the prearranged threshold; and if so, correcting the local time according to the rising edge arrival time of other second clock signals. The embodiment of the invention also provides a corresponding clock server. In the embodiment of the invention, the clock source desynchronization can be discovered, and the second clock signal sent by the clock source is not used for correcting the local time, thus avoiding the desynchronization of client machines in large areas due to the desynchronization of clock source.

The embodiment of the invention discloses a method and a system capable of synchronously restoring handshake. The method is as follows: when the emitting end of a state machine, which changes with time, is electrified again, state reset signals changing with time are sent to a receiving and controlling system in a manner of visible light signals; and the receiving and controlling system judges that the visible light signals are state reset signals when receiving the visible light signals, the state of the state machine is changed to the state indicated by the state reset signals. Due to the adoption of the method, the emitting end of a state machine can be in a synchronous state after being electrified again.
