Yarn Spindle Station-Passing Control Under MES Disconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in chemical fiber production is the inefficient and inconsistent station-passing of yarn spindles, which affects overall production pace and efficiency, leading to bottlenecks in output capacity.
Innovation Solution
A system involving a Manufacturing Execution System (MES), a first Programmable Logic Controller (PLC), and multiple second PLCs, where the first PLC acts as an intermediate layer to manage and process operational data, allowing automatic station-passing even when disconnected from the MES, ensuring smooth yarn spindle movement and reducing manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the first PLC continuously communicates with the MES to obtain station-passing indication information, then the station-passing efficiency is improved, but the system reliability deteriorates when network disconnection occurs
Solution Approach 1:
The first PLC stores historical station-passing indication information and operational data in advance before network disconnection occurs. When disconnected from the MES, the PLC uses this pre-stored data to continue controlling station-passing operations, ensuring uninterrupted production flow and maintaining system reliability during network issues.
2Reliability
If manual intervention is used to control station-passing, then the system reliability is maintained, but the productivity and production pace deteriorate
Solution Approach 1:
The first PLC automatically generates station-passing indication information and controls the yarn spindle station-passing process without requiring continuous manual intervention. The system monitors its own operational data and makes autonomous control decisions, achieving both high productivity through automation and reliability through consistent automated operation.
3Speed
If the first PLC processes and stores operational data locally, then the response speed for station-passing control is improved, but the device complexity increases
Solution Approach 1:
The patent extracts and stores only the essential operational data and station-passing indication information locally in the first PLC, rather than processing all possible data. This selective data extraction approach enables fast local response for station-passing control while keeping the PLC system complexity manageable by focusing only on critical information.

AI summary
Provided are a method for controlling automatic station-passing of yarn spindle, an electronic device and a storage medium, relating to the technical field of chemical fiber intellectualization. The system for controlling automatic station-passing of yarn spindle includes MES, first PLC and second PLCs. The method for controlling automatic station-passing of the yarn spindle includes: obtaining by first PLC second operational data of target station from second PLC corresponding to target station and obtaining first operational data of target station according to second operational data; and if first PLC is disconnected with MES, recording by first PLC the first operational data and sending station-passing indication information to second PLC, so that second PLC controls target station to execute yarn spindle station-passing task based on station-passing indication information, where station-passing indication information is permission of station-passing.
