Signal instruction synchronization processing method, system and equipment of channel group and storage medium

Abstract

The invention provides a signal instruction synchronization processing method, system and device of a channel group and a storage medium, and relates to but is not limited to the technical field of communication, and the method comprises the following steps: synchronizing a first system clock of a first main network node with a second system clock of a first slave network node of a first channel group; carrying out shortest path planning on the plurality of first slave network nodes through a first routing table of the first main network node to obtain a first transmission path comprising the plurality of first slave network nodes; obtaining a first transmission duration of the signal instruction reaching the end node of the first transmission path; and the first main network node determines a first sending time period of the signal instruction according to the execution period of the signal instruction and the first transmission duration. And the first slave network node determines the delay duration according to the first transmission duration, the transmitted second transmission duration and the trigger time of the next execution cycle. The system, the device and the storage medium apply the method, and the probability of executing synchronization from the network node can be improved.

Description

technical field [0001] The embodiments of the present application relate to but are not limited to the field of communication technologies, and in particular, relate to a method, system, device, and storage medium for synchronously processing signal instructions of channel groups. Background technique [0002] In industrial Ethernet, multiple devices (such as industrial control devices or robotic arms) are usually issued synchronous commands so that multiple devices can be synchronized. In the existing strategy, although channel groups are established for multiple devices, The master network node of the channel group sends control commands to each slave network node to realize the synchronization processing of commands, but due to the difference in network topology, the synchronization accuracy between slave network nodes is low in actual operation. Contents of the invention [0003] The following is an overview of the topics described in detail in this article. This summ...
