Yarn Spindle Transit Control Using MES and Heartbeat Path Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ensuring efficient and accurate transit of yarn spindle products between workstations in an assembly line is crucial for maintaining production efficiency, but existing systems face challenges in data management and communication stability, leading to potential delays and inaccuracies in transit decisions.
Innovation Solution
A method involving a first controller that centralizes data management between multiple second controllers and a Manufacturing Execution System (MES), using a heartbeat mechanism to ensure communication links are normal before sending transit indications, and selecting the best communication path to guarantee accurate transit control operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a first controller centralizes data management between multiple second controllers and MES, then system scalability and security are enhanced, but device complexity increases
Solution Approach 1:
The system is segmented into a first controller that manages data collection and communication with MES, and multiple second controllers that manage specific workstations. This segmentation allows the system to scale by adding more second controllers without significantly increasing the complexity of each individual controller, as each second controller maintains a standardized interface for data exchange.
2Reliability
If a heartbeat mechanism is used to ensure communication links are normal before sending transit indications, then network stability is improved, but data processing time increases
Solution Approach 1:
The heartbeat mechanism performs preliminary checks on communication link status before transit indications are sent. By continuously monitoring link status in advance through heartbeat signals, the system ensures that data is only transmitted when communication channels are verified to be normal, preventing wasted transmission attempts on failed links while maintaining reliable operation.
3Measurement precision
If the best communication path is selected to guarantee accurate transit control operations, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system uses feedback from heartbeat mechanisms and communication status monitoring to dynamically select the best communication path. Transit control decisions are based on real-time feedback about link quality and status, ensuring that data is routed through the most reliable available path while maintaining accurate control operations.
4Loss of information
If centralized data management is implemented, then loss of information is reduced, but device complexity increases
Solution Approach 1:
The first controller serves as an intermediary between second controllers and MES, centralizing data management functions. This intermediary role ensures that data from multiple workstations is collected, validated, and managed in a centralized location before being transmitted to MES, reducing the risk of data loss or inconsistency while maintaining a clear data flow architecture.

AI summary
A method for controlling transit of a yarn spindle, and apparatuses are provided, relating to the field of computer and automatic control. The method includes: taking (S201) each second controller as a target controller, and receiving target business data sent by the target controller; sending (S202) 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 (S203) the target transit indication sent by the manufacturing execution system; and sending (S204) the target transit indication to the target controller in a case of a communication link from the first controller to the target controller is in a normal state; where the target controller is configured to carry on the transit control operation for the yarn spindle product transiting the target workstation.
