Switching System, Method and Apparatus of Clock Circuit, and Non-transitory Readable Storage Medium

原文（中文）

A switching system, method and apparatus of a clock circuit, and a non-transitory readable storage medium are provided. A clock switching component is configured to collect a first clock signal generated by the clock generating component. The controller determines, based on the first clock signal and a second clock signal generated by a reference clock, a frequency offset between the clock generating component and the reference clock, and sends, in response to the first clock signal and the frequency offset both satisfy set anomaly conditions, a switching signal to the clock switching component. The clock switching component controls the clock generating component to switch a current clock to a standby clock based on the switching signal. The controller identifies, based on the first clock signal and the frequency offset, an operating state of the current clock.
