Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ensuring efficient and accurate transit of yarn spindle products between workstations in an assembly line is challenging due to communication link issues and data integrity problems, which affect the overall operation of the assembly line.
Innovation Solution
A system with a first controller intermediating between multiple second controllers and a manufacturing execution system, ensuring data accuracy by only receiving business data when communication links are normal, using heartbeat protocols to verify link status, and employing transit control devices for precise product flow management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the first controller receives business data from multiple second controllers continuously, then the data processing efficiency is improved, but the risk of receiving erroneous data due to communication link failures increases
Solution Approach 1:
The system performs preliminary verification of communication link status using heartbeat protocols before receiving and processing business data. This advance check prevents erroneous data from being processed, resolving the contradiction between continuous data processing efficiency and data accuracy by ensuring links are operational beforehand.
Solution Approach 2:
The system implements feedback mechanisms where second controllers send heartbeat information to the first controller, which continuously monitors communication link status. This feedback loop enables the system to detect link failures and adjust data reception accordingly, maintaining both processing efficiency and data reliability.
2Reliability
If the system implements communication link status verification before data reception, then data accuracy is improved, but the operation complexity increases
Solution Approach 1:
The system employs self-service mechanisms where controllers automatically perform heartbeat protocols and status verification without external intervention. This automation maintains high data accuracy while minimizing operational complexity by eliminating manual checking requirements.
Solution Approach 2:
Communication link verification is performed automatically as a preliminary step before data reception, embedded within the system's normal operation flow. This approach ensures data accuracy without adding significant operational complexity, as the verification is integrated rather than separate.
3Reliability
If the first controller acts as an intermediary for all data transmission between second controllers and the manufacturing execution system, then data management control is improved, but the device complexity increases
Solution Approach 1:
The first controller serves as an intermediary between second controllers and the manufacturing execution system, centralizing data management and improving control reliability. This intermediary role consolidates communication pathways and enables unified monitoring, justifying the increased structural complexity through enhanced data management capabilities.
Solution Approach 2:
The first controller performs multiple functions including receiving business data, verifying communication link status, forwarding data to the manufacturing execution system, and coordinating transit control operations. This multi-functionality consolidates what could be multiple separate components into a single versatile controller, managing complexity while maintaining strong data management control.
4Reliability
If the system uses heartbeat protocols to verify communication link status, then the reliability of data transmission is improved, but the time consumption for verification increases
Solution Approach 1:
The system uses periodic heartbeat protocols where second controllers send status information at regular intervals rather than continuously. This periodic verification maintains communication reliability while minimizing time consumption by checking only at necessary intervals rather than constantly monitoring.
Solution Approach 2:
Heartbeat verification is performed preliminarily and efficiently before data transmission, using lightweight status checks that consume minimal time. This preliminary verification ensures communication reliability without significant time loss, as the actual data transmission only occurs after quick confirmation of link status.

AI summary
Provided is a method for controlling transit of a yarn spindle, an electronic device and a storage medium, relating to the field of computer and automatic control. The method includes: taking each second controller as a target controller, and receiving target business data sent by the target controller when determining that a communication link from the target controller to the first controller is in a normal state; sending the target business data to the manufacturing execution system, where the manufacturing execution system is configured to obtain a target transit indication based on the target business data, and send the target transit indication to the first controller; receiving the target transit indication sent by the manufacturing execution system; and sending the target transit indication to the target controller; where the target controller is configured to carry on the transit control operation for the yarn spindle product transiting the target workstation.
