Network timing method and device

Abstract

The embodiment of the invention provides a network timing method and device. The network timing method comprises a step of obtaining historical timing data before a current time when an adaptive timing instruction is received, a step of calculating and obtaining a historical timing total difference corresponding to each historical timing time point, a step of obtaining a current timing total difference of the current time through a preset algorithm according to the historical timing total difference corresponding to each historical timing time point, a step of determining a difference betweenthe current timing total difference and a historical timing total difference of a last historical timing time point in the historical timing time point as a timing difference of the current time, anda step of adjusting the time of the current time according to the timing difference of the current time to complete the adaptive timing of this time. Through the scheme, the amount of redundant data in a network can be reduced on the basis of ensuring the accuracy of the equipment time.

Description

technical field [0001] The present invention relates to the technical field of network timing, in particular to a method and device for network timing. Background technique [0002] With the development of computer network technology and video technology, the time synchronization of computers or network cameras in the network plays an increasingly important role. [0003] Under normal circumstances, in network devices, such as computers or network cameras, the calculation of device time is performed through the hardware crystal oscillator chip in the device, but limited by factors such as manufacturing process, equipment cost, hardware design, etc., the hardware crystal oscillator chip is used in the device. There will be a certain error in the operation, and the error has an important impact on the operation of the equipment. For example, for the linkage system of multiple network cameras, multiple network cameras monitor different locations in the same area. When the vide...

However, because the timing interval is relatively short, a lot of short-time timing data packets will be introduced into the network, resulting in an increase in the amount of redundant data in the network
