Abstract

The invention provides a time synchronization method, device and system for preventing time rollback, and the method comprises the steps: obtaining the first time of a first type of equipment and the second time of a second type of equipment at a moment before the signal of the second type of equipment is shielded, calculating the difference value between the first time and the second time, and obtaining the difference value between the first time and the second time; in the process that the signal of the second type of equipment is shielded, the third time of the second type of equipment is obtained, the third time of the second type of equipment is synchronized according to the difference value, the time after the second type of equipment is synchronized is obtained, and the problem that time synchronization cannot be carried out after the signal is shielded in the prior art is solved.

Description

technical field [0001] The present application relates to the technical field of time synchronization, and in particular, to a time synchronization method, device, time synchronization system, processor, and computer-readable storage medium for preventing time rollback. Background technique [0002] In the existing solution, when a device that obtains time through an internal clock crystal oscillator passes through a tunnel, it cannot receive a signal, that is, the signal is in a shielded state, so that the device cannot enter time synchronization, resulting in time rollback. SUMMARY OF THE INVENTION [0003] The main purpose of the present application is to provide a time synchronization method, device, time synchronization system, processor and computer-readable storage medium for preventing time rollback, so as to solve the problem that time synchronization cannot be performed after the signal is shielded in the prior art. [0004] In order to achieve the above object, ...
