Abstract

The invention discloses a time synchronization method, which comprises the steps of receiving the data sent from a time service system, recording a first time for receiving the data, acquiring a second time through parsing the data on the condition that the received data includes the time information and the time information is the system time of the time service system, calculating the time offset of a slave system relative to the time service system, calculating the time stamp of network data on the condition that the received data are just the network data, and adopting the time stamp as the system time of the slave system. According to the technical scheme of the invention, the time offset is the difference value between the first time and the second time and the time stamp is the sum value of the first time and the latest time offset obtained through calculation. Based on the above method, the time synchronization function for all slave systems of a simulation system is realized without the arrangement of any time synchronization apparatus. Meanwhile, the system is low in cost and the operation of the simulation person is simplified. The workload of the simulation person is lowered. The invention also discloses a time synchronization apparatus and a simulation system.

Description

technical field [0001] The invention belongs to the technical field of simulation, and in particular relates to a time synchronization method, a time synchronization device and a simulation system. Background technique [0002] The simulation system usually includes multiple subsystems, and the simulation processing of a certain function is realized through cooperation among multiple subsystems. During the simulation process, the time synchronization of multiple subsystems determines the correctness of the data in the entire simulation process and provides an accurate time basis for data analysis. If the system time of each subsystem in the simulation system is different, it will cause time errors in the data information received by the subsystem at a certain moment, or the subsystem does not receive the specified data within the specified time, or the data received by the subsystem appears Larger time deviation. [0003] At present, the way to realize the time synchroniza...
