Textile Machine Section Bus Layout for Fast Reliable Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern textile machines with many communication-capable units face limitations in reliable and quick communication due to the limited number of bus participants and information backlogs on section buses, leading to signal delays and disruptions, especially during critical operations like starting and parking.
Innovation Solution
Implementing a textile machine with at least two section buses connected to the section control, where one section bus handles similar individual drives and sensors, and the other handles job control units, allowing for distributed communication and reducing the number of bus participants, enabling quick and reliable information exchange while accommodating modern and legacy components with different protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of bus participants is increased to accommodate many communication-capable units, then the coverage of communication units is improved, but the communication speed and reliability deteriorate due to information backlogs
Solution Approach 1:
The patent divides the single section bus into multiple section buses (first section bus, second section bus, etc.). Each bus handles a subset of communication-capable units, reducing the number of participants per bus and eliminating information backlogs while maintaining comprehensive coverage across all units.
2Quantity of substance
If the number of bus participants is increased to accommodate many communication-capable units, then the coverage of communication units is improved, but the reliability of communication deteriorates due to signal delays
Solution Approach 1:
By segmenting the bus system into multiple independent section buses, each bus maintains reliable communication with fewer participants. The section control coordinates between buses to ensure overall system reliability without the signal delays that occur in overloaded single-bus systems.
3Speed
If more section buses are implemented to reduce bus participants, then the communication speed is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple section buses at the section control level, allowing the system to benefit from faster communication on each individual bus while the section control manages the complexity of coordinating between buses. This hierarchical merging approach distributes complexity management effectively.
4Reliability
If more section buses are implemented to reduce bus participants, then the communication reliability is improved, but the device complexity increases
Solution Approach 1:
Multiple section buses are merged at the section control level with a coordinated communication scheme. The section control manages data exchange between buses, ensuring high reliability through reduced participant loads on each bus while systematically managing the added complexity through centralized coordination.
