Temperature control system and method for CPS-based ring spinning intelligent workshop

Abstract

The invention provides a temperature control system for a CPS-based ring spinning intelligent workshop. The temperature control system for a CPS-based ring spinning intelligent workshop comprises a physical layer, a communication layer, an information layer and a control layer. The physical layer is each physical entity related to the temperature of the ring spinning intelligent workshop. The communication layer collects real-time temperature data of each physical entity of the physical layer and transmits the real-time temperature data to the information layer through the ring spinning industrial internet. The information layer receives the real-time temperature data and performs intelligent calculation to form a mirror image of the physical entity. And the control layer adjusts the air outlet volume, the air outlet direction and the air outlet temperature of the air conditioner of the ring spinning intelligent workshop according to the mirror image of the physical entity so as to realize the closed-loop accurate control on the temperature of the ring spinning intelligent workshop. The invention also provides a CPS-based ring spinning intelligent workshop temperature control method, and a control strategy is formed by analyzing large data of the ring spinning temperature to realize the closed-loop accurate control on ring spinning intelligent workshop temperature. The performance of the temperature control system is reliable and the control result is accurate, and the temperature control system is suitable for large-scale popularization and use.

Description

technical field [0001] The invention relates to a temperature control system, in particular to a CPS-based closed-loop precise temperature control system for an intelligent workshop of ring spinning. Background technique [0002] Temperature and humidity are one of the important factors affecting the yield and quality of yarn. It is closely related to the moisture regain and tension of the yarn fiber, and has a great impact on the spinning process. Therefore, each process in the production process of ring spinning yarn, especially drawing frame, roving and winding, has quite high requirements on the temperature and humidity in the production environment. [0003] Early spinning mills generally used simple methods such as natural ventilation to adjust the temperature of the production environment. Although the temperature balance was improved to a certain extent, the effect was not obvious, and the quality of the yarn produced in this environment was not high. [0004] With ...

Problems solved by technology

[0003] Early spinning mills generally used simple methods such as natural ventilation to adjust the temperature of the production environment. Although the temperature balance was improved to a certain extent, the effect was not obvious, and the quality of the yarn produced in this environment was not high.

[0004] With the continuous development of air-conditioning technology in spinning mills and the continuous improvement of automation technology, the automatic temperature control technology in spinning workshops has also made great progress, but it has not achieved precise control of temperature, and the control of temperature in intelligent workshops seems to be a problem. very necessary
