Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control systems require manual data format matching and timing adjustments when adding or removing control services, leading to increased man-hours and inflexible responses to diverse needs.
Innovation Solution
A control system with a mediation device that acquires individual command values from multiple control services, assigns acquisition times, generates timing instructions, and integrates command values to produce an output command for a control target, facilitating flexible combination of control services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If control services are added or removed in a conventional control system, then the system can be reconfigured, but manual data format matching and timing adjustments are required, increasing man-hours and reducing flexibility
Solution Approach 1:
The patent introduces a mediation device as an intermediary between multiple control services and the control target. This mediator automatically performs data format matching and timing synchronization, eliminating the need for manual configuration adjustments when control services are added or removed. The mediation device receives individual command values from control services, standardizes their formats, synchronizes their timing, and generates unified output commands, thereby resolving the technical contradiction between system flexibility and configuration complexity.
2Productivity
If multiple control services control the same target simultaneously, then advanced real-time control is achieved, but coordination of command timing and formats becomes complex
Solution Approach 1:
The patent merges multiple individual command values from different control services into a single unified output command. The mediation device combines the command values, applies format standardization, performs timing synchronization, and generates one coordinated output command for the control target. This merging approach enables advanced real-time control through multiple services while automatically handling the coordination complexity, resolving the contradiction between productivity and device complexity.
3Reliability
If manual matching of data formats is performed for each control service, then compatibility is ensured, but the process requires significant manual effort and time
Solution Approach 1:
The mediation device performs self-service by automatically matching and standardizing data formats from multiple control services without requiring manual intervention. The device receives diverse data formats from control services, automatically identifies and applies appropriate format conversions, and ensures compatibility. This automated format matching ensures data reliability while eliminating the time-consuming manual configuration process, resolving the contradiction between reliability and time loss.

AI summary
A control system includes a plurality of control services and a mediation device. The control services each output an individual command value for controlling a control target. Mediation device acquires the individual command values from the control services and generates, based on the acquired individual command values, an output command value to be given to the control target. Mediation device assigns, to each of the individual command values, an acquisition time indicating the time at which the individual command value was acquired, notifies the control services of command sharing information including the individual command values and the acquisition times, generates timing instruction information for specifying a next instruction time for each of the control services, based on the number of control services and the acquisition time of the individual command value of each of the control services, and notifies each of the control services of the generated timing instruction information.
