Joint clock acquisition method, apparatus and device, and computer readable storage medium

Abstract

The invention discloses a joint clock acquisition method, apparatus and device, and a computer readable storage medium. The method comprises the steps of: obtaining clock signals of at least two clock sources; calculating a regulation coefficient of the clock signals, and adjusting the difference value of the clock signals and a preset reference value by using the regulation coefficient to obtain a confidence difference value; and obtaining a joint clock according to the confidence difference value of each clock signal and the preset reference value. According to the technical scheme, the clock signals of at least two clock sources are obtained, the difference value between the clock signals and the preset reference value is adjusted through the regulation coefficient, the clock signals of the clock sources are referenced, the influence of the accuracy degree of the clock sources on the joint clock is considered through the regulation coefficient, the joint clock is obtained by utilizing the confidence difference value of the clock signals and the preset reference value, the defect that the time service clock signals are unstable in the prior art is overcome, and meanwhile, the obtained joint clock is more accurate compared with the clock signal of any clock source.

Description

technical field [0001] The present invention relates to the technical field of time service, in particular to a combined clock acquisition method, device, equipment and computer-readable storage medium.
