Clock source system, clock synchronization system and clock synchronization method

Abstract

The invention provides a clock source system, a clock synchronization system, a clock synchronization method, electronic equipment and a computer readable storage medium, and the clock source system comprises a first timer module which is used for obtaining a first clock signal of the clock source system and a second clock signal of a subsystem; a deviation acquisition module which is used for acquiring clock deviation according to the first clock signal and the second clock signal, wherein the first timer module is further used for acquiring clock skew and sending the clock skew to the subsystem to indicate the subsystem to calibrate a second clock signal so as to synchronize with a local clock of the clock source system, thereby ensuring complete synchronization of communication betweenthe clock source system and the subsystem, effectively solving the problem that data transmission between modules with different clock sources or time references is not synchronous, and guaranteeing the real-time performance and consistency of data transmission between a clock source system and a subsystem.

Description

technical field [0001] The present application relates to the technical field of clock synchronization, and in particular to a clock source system, a clock synchronization system, a clock synchronization method, electronic equipment, and a computer-readable storage medium. Background technique [0002] In various large-scale real-time electrical systems, a clock source or time reference is often configured for the main system and each subsystem to provide real-time clocks for each system (main system and subsystem). Exemplarily, main system A is provided with a clock by clock source A, and subsystem B is provided with a clock source or time reference by clock source B. After the two systems are connected through relevant ports, data exchange occurs. However, since the main system A and the subsystem B work on their respective clock sources or time bases, the communication between the main system A and the subsystem B will have the risk or phenomenon of being out of synchroni...
