Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication channels are used to transmit control information in a distributed control system, then network connectivity is achieved, but transmission performance degradation occurs that hinders network performance improvement
Solution Approach 1:
The patent segments communication into multiple independent communication paths between the central communication device and terminal communication devices. By dividing the communication load across multiple paths rather than relying on a single channel, the system prevents transmission performance degradation on one path from affecting overall network performance, thus resolving the contradiction between achieving network connectivity and maintaining transmission performance.
2Speed
If hardware changes are made to improve network performance, then communication speed increases, but development time and cost increase due to manual configuration requirements
Solution Approach 1:
The patent implements automatic communication path setting where the central communication device autonomously determines optimal communication paths based on communication performance data without requiring manual configuration. The system self-adjusts communication parameters and path routing, eliminating the need for developer intervention when improving communication speed through hardware changes, thus resolving the contradiction between increasing communication speed and reducing development time.
3Stability of the object's composition
If communication paths are fixed, then system stability is maintained, but adaptability to changing communication performance conditions is reduced
Solution Approach 1:
The patent establishes communication paths dynamically based on real-time communication performance data rather than using fixed predetermined paths. The central communication device continuously monitors communication performance and automatically adjusts path routing to maintain optimal performance conditions. This dynamic adaptation allows the system to maintain stability through continuous optimization while adapting to changing communication conditions, resolving the contradiction between system stability and adaptability.

AI summary
In a distributed control system including a central communication device, terminal communication devices to which target devices to be controlled are connected, and a network including multiple communication paths connecting the central communication device and terminal communication devices, each terminal communication device includes a calculation input/output performance storage unit storing input/output performance of a calculation unit for controlling the target devices to be controlled and a control input/output performance storage unit storing the performance of the input/output control units of the target devices to be controlled, and the central communication device collects input/output performance information previously stored in these storage units, determines communication paths of the terminal communication units and a packet division method in such a manner that an amount of a communication data of a network and response performance requested of the distributed control system are satisfied, on the basis of the collected input/output performance information and sets the determination results in the terminal communication devices.
