Solution Overview
Problem
Existing voltage determination methods for chargeable voltage sources, particularly in submarine on-board power supply systems, face challenges due to corrosion and impaired conductivity in measuring arrangement contacts and conductive connections, leading to inaccurate voltage monitoring and charging, which can be unsafe and unreliable.
Innovation Solution
A method using a variable resistor connected in parallel with a voltmeter, allowing successive voltage measurements with different reference resistors to diagnose the condition of electrical lines by determining their electrical resistance, thereby assessing corrosion or damage, and ensuring reliable voltage determination and charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional measuring arrangements are provided for precise voltage determination, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by performing self-diagnostics of the measuring arrangement before actual voltage measurements. The system checks the electrical lines and contacts for corrosion or impaired conductivity using test signals, and only proceeds with measurements when the measuring arrangement is confirmed to be in good condition. This prevents inaccurate measurements due to degraded components without requiring redundant measuring arrangements.
2Reliability
If operating age of measuring arrangement increases, then experience and data accumulation improve, but reliability deteriorates due to corrosion and impaired conductivity
Solution Approach 1:
The patent implements feedback by continuously monitoring the condition of the measuring arrangement's electrical lines and contacts. The system measures voltage drops across known reference resistors and compares them against expected values to detect corrosion or conductivity issues. When degradation is detected, the system generates alerts or error signals to indicate that the measuring arrangement requires maintenance or replacement, enabling proactive reliability management.
