Solution Overview
Problem
Existing control systems for compressed air generation, treatment, storage, and distribution face challenges in precise monitoring and diagnosis, often relying on central control devices that manage significant data flows and require more precise control and evaluation methods.
Innovation Solution
An electronic control device that uses component-related models to simulate and evaluate operational data, allowing for precise control, regulation, diagnosis, and monitoring by determining probable malfunctions through comparison with real measurement values, and employing plausibility criteria to identify deviations and output error messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a central control device controls and monitors a large number of components, then system-wide control capability is improved, but data management complexity and device burden increase
Solution Approach 1:
The patent divides the control system into distributed electronic control devices at component level and a higher-level central control device. Each component (compressor, dryer, filter, tank) has its own control device that performs local control, monitoring, and self-diagnosis using component-specific models, thereby segmenting the data management burden from the central device while maintaining system-wide coordination capability.
Solution Approach 2:
The patent introduces communication interfaces and data exchange protocols as intermediaries between component-level control devices and the central control device. These intermediaries manage data flow, filter information, and enable coordinated control without requiring the central device to directly manage all raw data from numerous components, thus reducing central device complexity.
2Measurement precision
If component-related models are used for simulation and evaluation, then diagnosis precision and control accuracy are improved, but computational requirements and device complexity increase
Solution Approach 1:
The patent implements component-specific control devices with tailored models for each type of component (compressor models, dryer models, filter models, tank models). Each control device uses locally relevant models and parameters appropriate to its specific component, enabling precise local diagnosis and control without requiring all components to handle complex computational tasks, thus balancing precision with manageable complexity.
