Edge computing-based spinning CPS (cyber-physical system) and real-time task processing method thereof

Abstract

The invention provides an edge computing-based spinning CPS (cyber-physical system). The CPS comprises a physical layer and an information layer; the physical layer and the information layer are connected through a communication layer so as to interact with each other; the information layer is arranged in a cloud center; the computing and storage resources of the cloud center are distributed to the physical entities of the physical layer in the form of edge computing nodes; the edge computing nodes are connected with the physical entities; the edge computing nodes are also connected with the cloud center through the communication layer; and the sequential real-time tasks of the physical entities are processed through the edge computing nodes. The present invention also provides a real-timetask processing method of the edge computing-based spinning CPS (cyber-physical system). According to the edge computing-based spinning CPS (cyber-physical system) and the real-time task processing method thereof of the invention, the computing and storage resources of the cloud center are distributed to the physical entity attachments by means of an edge computing node mode; on the basis of a principle of ''proximity processing, proximity service'', the real-time performance requirement and security requirement of the spinning CPS can be well satisfied; the security risks of task transmission can be decreased; and bandwidth can be saved. The CPS is suitable for being popularized widely.

Description

technical field [0001] The invention relates to a spinning CPS based on edge computing and a real-time task processing method thereof, belonging to the technical field of spinning. Background technique [0002] Spinning is a process of changing fibers from a chaotic state to an orderly arrangement along the longitudinal direction. It is a typical multi-process, continuous, large-scale production, showing high speed and large dynamic characteristics. The core of the spinning intelligent factory is the CPS system (information physical system), figure 1 A schematic diagram of the spinning CPS is shown. The physical space of the spinning CPS is composed of elements such as people, machines, materials, methods and rings involved in yarn production in the spinning production workshop. The information space is the mirror image of the physical space, and the processing of various data in the physical space is continuously iteratively optimized into a knowledge base for spinning de...
