Industrial Internet-of-Things for adaptively adjusting time slot window and bandwidth sharing based on TSN

Abstract

The invention requests to protect an industrial Internet-of-Things for adaptively adjusting a time slot window and bandwidth sharing based on a TSN, and the method specifically comprises the followingsteps: firstly, classifying different types of traffic in a network according to a set traffic class, putting the traffic into corresponding queues according to an FIFO principle, and when a channelis idle, queuing frames to be sent exist; checking the corresponding door, and if the corresponding door is closed, waiting the corresponding door to be opened; if the corresponding door is in an openstate, entering the next step; checking a corresponding time slot window, and preparing for transmission if a transmission condition is met; if the transmitted channel is idle, smoothly sending data;when the transmitted channel is busy, enabling the system to activate an adaptive bandwidth sharing ABS mechanism and a dynamic adaptive time slot windowing ASW mechanism; and when the QoS of the system is in a normal range, enabling the system not to need to change a transmission structure, and when the QoS is close to a threshold value, namely the delay is close to STHigh, enabling the system to adjust the corresponding gating entry as required.

Description

technical field [0001] The invention belongs to the field of industrial internet of things, and in particular relates to a method of using a time-sensitive network to ensure the quality of key load communication in industrial communication. Background technique [0002] At present, the development of Internet of Things technology has brought many ideas and methods to solve problems, which can better promote the construction of a high-tech and low-energy society. The Industrial Internet of Things is regarded as one of the components of the Internet of Things. Currently, it is mainly represented by Cyber-Physical Systems (CPS) dominated by the American Industrial Internet and German Industry 4.0. It mainly integrates big data, cloud computing , sensors or controllers and other technologies are integrated into each process of production to improve production efficiency and product quality, thereby reducing production costs and transforming traditional industries into intelligen...

AI Technical Summary

Problems solved by technology

[0006] Although these Ethernet technologies provide deterministic real-time properties and can transport real-time and non-real-time traffic on the same medium, they are not compatible with each other, so different technologies cannot operate on the same physical medium

Significantly limited interoperability and interconnectivity

[0007] The present invention mainly solves the deterministic delay of ST data transmission in the field of industrial Internet of Things and ensures the timeliness of transmission
