Problems solved by technology

[0004] However, once the NTP server is not available, the time between the terminals will not be aligned
For example, after a long period of use, the NTP server goes down or cannot be recovered normally due to an abnormal power failure, and the service link between the terminal and the terminal is disconnected, causing the terminal to fail to synchronize the time normally, which in turn leads to the failure of normal scheduling of time-related tasks.
The existing time synchronization method completely relies on the NTP server for time synchronization, and the reliability of time synchronization is not high

Abstract

The invention provides a time tick method and device for a private network cluster terminal, and the method comprises the steps: transmitting temporary multicast group information to at least one terminal, wherein the temporary multicast group information comprises the multicast address of a temporary multicast group; if the information that the at least one terminal joins in the temporary multicast group is received, acquiring a multicast time tick message; and sending the multicast time tick message to the multicast address, so as to enable the at least one terminal to receive the multicasttime tick message from the multicast address and complete time tick according to the multicast time tick message, thereby improving the multicast time tick message transmission efficiency, reducing the possibility of congestion of a backbone network, realizing the receiving synchronization of the multicast time tick message, and improving the time tick accuracy and reliability. Moreover, the method and device do not depend on remote clock sources such as a GPS, and the time synchronization reliability is improved.

Description

technical field [0001] The invention relates to communication technology, in particular to a time synchronization method and device for private network cluster terminals. Background technique [0002] Private network cluster communication refers to the communication network built within some industries, departments or units to meet their needs for organizational management, safety production, dispatching and commanding, etc., and its service object is often an industry or enterprise. [0003] At present, the terminal automatic time synchronization in the cluster network application of the private network adopts the same scheme as that of the public network, that is, the time is synchronized by using a Network Time Protocol (NTP) server. Specifically, all terminals that need time synchronization perform periodic time synchronization to the NTP server. NTP can synchronize the terminal with a server or a clock source (such as the Global Positioning System (Global Positioning S...
