Signal synchronizing method and system thereof

Abstract

A synchronizing method of signal includes setting time step size value , sending synchronous signal to synchronized party by synchronizing source at each signal switching over point , comparing whether its current signal state is consistent to signal state to be switched on by synchronizing source or not and regulating synchronized party current signal state to elongate said step size value if it is or otherwise regulating its next signal state to shorten said step size value after each synchronized party receives synchronous signal .

Description

technical field [0001] The invention relates to signal processing technology, in particular to a signal synchronization method and system thereof. Background technique [0002] Multiple running systems scattered in physical space, even if they start running at the same time in the initial stage, and the signal occurrence rules of each running system are consistent, but due to the randomness and delay of each running system in the running process, and The software and hardware of each operating system run independently. After running for a period of time, there will inevitably be a state where multiple operating systems are running out of sync (that is, an out-of-synchronization state), which will affect the communication between multiple operating systems. Continuity, so it is necessary to carry out signal synchronization control on multiple operating systems dispersed in physical space, so that multiple operating systems can maintain communication continuity during operatio...

AI Technical Summary

Problems solved by technology

[0006] (1) When the signal of the synchronized operating system deviates greatly from the reference synchronization signal of the main synchronization source, if the synchronized operating system immediately adjusts its own signal and the main synchronization signal after receiving the synchronization signal from the main synchronization source If the reference signal of the source is synchronized, the degree of adjustment may be relatively large, so the signal of the synchronized operating system will have a signal state jump phenomenon, and this jump will affect the effect of signal synchronization

[0007] (2) If there is a deviation between the clock of the synchronized operating system and the clock of the main synchronization source, it may occur that each time the synchronized operating system receives a synchronization signal from the main synchronization source, the synchronization processing performed will cause each The signal jump phenomenon occurs in the synchronized operating system, so the frequency of signal jump in each synchronized operating system is higher, thus affecting the signal quality of each synchronized operating system

[0008] (3) There will be a transmission delay problem when the main synchronization source sends the synchronization signal to each synchronized operating system, and the time delay caused by the main synchronization source transmitting the synchronization signal to each synchronized operating system is not the same , so the signal synchronization processing performed by each synchronized operating system after receiving the synchronization signal cannot be completely accurately synchronized with the signal of the main synchronization source, and each synchronized operating system cannot be completely accurate Signal synchronization is achieved, so the accuracy of signal synchronization is not very high, especially for transmission lines with large transmission delays, this phenomenon is more serious
