Automation Power Control Using Buffered Environmental Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing automation devices burden the CPU module with additional load by requiring it to cyclically retrieve and preprocess environmental data, which can lead to increased processing demands and potential delays in control program execution.
Innovation Solution
Storing influencing variables in the source module with consistent data blocks, allowing the CPU module to access the most up-to-date environmental data without additional preprocessing, and ensuring comprehensive error diagnosis through a user-oriented interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the CPU module cyclically retrieves and preprocesses environmental data, then comprehensive error diagnosis is enabled, but the processing load on the CPU module increases
Solution Approach 1:
The patent extracts the environmental data storage function from the CPU module and places it in a separate buffer memory. This allows the CPU to access pre-stored environmental data without cyclically retrieving and preprocessing it, thereby reducing processing load while maintaining error diagnosis capability.
Solution Approach 2:
The patent implements preliminary action by having environmental data continuously stored in the buffer memory before the CPU needs to access it. This eliminates the need for the CPU to perform time-consuming retrieval and preprocessing operations at the moment of need, reducing processing load while ensuring data availability for error diagnosis.
2Productivity
If environmental data is stored in a separate buffer memory, then the CPU module's processing load is reduced, but the system complexity increases
Solution Approach 1:
The buffer memory component serves multiple functions: it stores environmental data continuously, provides data to the CPU on demand, and enables error diagnosis capabilities. This multi-functionality justifies the added component while delivering significant processing efficiency benefits.
3Loss of time
If the CPU module accesses environmental data in real-time, then timely evaluation of temperature conditions is possible, but the data access operation becomes more complex
Solution Approach 1:
Environmental data is continuously pre-stored in the buffer memory as it becomes available from sensors. When the CPU needs to evaluate temperature conditions, the data is already prepared and immediately accessible, achieving real-time response without complex data retrieval or preprocessing operations.
