Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual control methods are used for yarn spindle transit, then operational flexibility is maintained, but transit efficiency and production rhythm are reduced
Solution Approach 1:
The system enables automatic transit control where the PLC independently manages yarn spindle transit operations based on workstation status data, eliminating the need for continuous manual intervention and significantly improving transit efficiency while maintaining operational autonomy
Solution Approach 2:
The patent replaces manual mechanical control with an automated PLC-based control system that uses electronic data processing and automated decision-making to manage yarn spindle transit, thereby enhancing productivity through systematic automation
2Manufacturing precision
If complex control systems are implemented to manage yarn spindle transit, then transit precision is improved, but system complexity and implementation difficulty increase
Solution Approach 1:
The PLC serves as an intermediary control device that simplifies the control architecture by centralizing transit management functions, reducing the complexity of direct point-to-point control while maintaining precise transit control through standardized data processing protocols
Solution Approach 2:
The control system is segmented into modular components where the PLC handles transit control logic, workstation systems provide status data, and the MES oversees overall production coordination, allowing each module to be optimized independently while maintaining precise integrated control
3Productivity
If real-time monitoring and automated decision-making are implemented, then production flow optimization is achieved, but network structure complexity and data processing requirements increase
Solution Approach 1:
The system merges transit control functions, workstation monitoring, and data processing into an integrated PLC-based platform that communicates through standardized protocols, reducing network complexity by consolidating multiple functions into a unified control architecture while maintaining real-time production flow optimization

AI summary
Provided are a method and apparatus for controlling automatic transit of a yarn spindle, an electronic device and a storage medium, relating to the field of chemical fiber intelligent technology. The method includes that: a first PLC acquires second service data of a target workstation from a second PLC corresponding to the target workstation, obtains first service data of the target workstation based on the second service data, the second service data includes a compulsory transit variable being equal to 1 (S201); the first PLC sends the first service data to an MES, receives transit indication information which is determined based on the compulsory transit variable by the MES (S202); and the first PLC analyzes the transit indication information to obtain an analysis result, returns the analysis result to the second PLC to perform a yarn spindle transit task based on the analysis result by the second PLC (S203).
