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 the complexity of coordinating multiple yarn spindle workstations, leading to potential inefficiencies and operational disruptions.
Innovation Solution
A system and method involving a first controller that integrates with a manufacturing execution system (MES) and multiple second controllers, where business data is centralized and transit indications are sent only when communication links are normal, using a heartbeat mechanism to ensure accurate and efficient transit control operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a centralized control system is used to coordinate multiple yarn spindle workstations, then transit control accuracy is improved, but system complexity increases
Solution Approach 1:
The control system is segmented into a first controller for centralized coordination and multiple second controllers for local workstation control. This segmentation allows the first controller to maintain overall transit control accuracy while distributing control functions to reduce central system complexity.
Solution Approach 2:
The first controller acts as an intermediary between the manufacturing execution system and the multiple second controllers. It receives transit indications from the MES and distributes them to appropriate second controllers, simplifying the overall system architecture while maintaining precise transit control.
2Adaptability or versatility
If multiple second controllers are used to manage different workstations, then system scalability is improved, but data processing burden increases
Solution Approach 1:
The first controller extracts and centralizes the coordination of business data from multiple second controllers. By collecting business data from all second controllers and managing it centrally, the system achieves scalability while the first controller optimizes data processing to reduce overall computational burden.
Solution Approach 2:
Multiple second controllers are merged into a coordinated system under the first controller. They collectively manage different workstations and share the data processing load, allowing the system to scale while distributing the processing burden across multiple components.
3Reliability
If real-time communication links are monitored before sending transit indications, then system reliability is improved, but communication overhead increases
Solution Approach 1:
The first controller performs preliminary checks of communication link status before sending transit indications to second controllers. By verifying link normality in advance, the system ensures reliable data transmission while the preliminary nature of this check minimizes time overhead.
Solution Approach 2:
The system implements feedback mechanisms where the first controller monitors communication link status and adjusts its transmission behavior accordingly. This feedback loop ensures that transit indications are only sent when communication links are normal, improving reliability while the efficient feedback design minimizes time overhead.

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 each second controller as a target controller, and receiving target business data sent by the target controller; 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 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.
