Oxygen Reduction Control Verification for Authorized Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oxygen reduction systems lack a method to verify and ensure that only approved or released system functions are used, posing a safety risk due to the potential use of non-approved assemblies or plug-in cards without safety examination.
Innovation Solution
A verification method using a programmable control module to detect system functions, generate a license data set, compare it with a verification data set, and output notifications or deactivate functions if a license violation is detected, ensuring only authorized functions are operational.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the control and regulation system is expanded after delivery with additional assemblies and plug-in cards, then the adaptability and versatility of the system is improved, but the reliability deteriorates due to potential use of non-approved components without safety examination
Solution Approach 1:
The patent implements a verification method that checks system functions before they are activated. The control module reads a verification data set containing approved function identifiers and compares them against the currently active functions. This preliminary verification ensures that only safety-examined and approved components and functions can be activated, preventing unauthorized expansions from compromising system reliability while still allowing adaptability through approved modifications.
2Ease of operation
If decentralized control modules with expandable functions are used, then the ease of operation and customization is improved, but the difficulty of detecting and measuring unauthorized modifications increases
Solution Approach 1:
The patent implements a continuous feedback mechanism where the control module regularly reads the verification data set and compares it against currently active system functions. This feedback loop automatically detects any unauthorized modifications or non-approved assemblies by identifying functions that are active but not present in the verified data set. The system provides immediate detection and can trigger alarm signals or deactivate unauthorized functions, making unauthorized modifications easily detectable despite system expandability.

AI summary
A method for verifying system functions of an oxygen reduction system, said functions being used during operation. The oxygen reduction system reduces or maintains an oxygen concentration level in a protection region by supplying inert gas and to monitor or increase the oxygen concentration level, which has been previously reduced in the protection region or in a monitoring region. The method comprises:Detecting system functions being used during the operation of the oxygen reduction system.generating a license data set which contains licenses used by the system functions being used.reading a verification data set provided on a storage medium, wherein the verification data set contains at least one existing license—determining a license violation if each license used is not contained in the verification data set.outputting an error message, or deactivating at least one system function if a license violation is determined.
