Solution Overview
Problem
Existing power supply systems in industrial facilities face challenges such as increased risk of unplanned shutdowns due to single power supply failures, lack of diagnostic data for root cause analysis, and inefficient space utilization, leading to downtime and financial losses.
Innovation Solution
A power supply communication architecture that includes a communication module interfacing with power supplies via channels supporting specific protocols, transmitting diagnostic data like live parameters, event flags, and service life data, and enabling graphical user interfaces for users to change operational settings and monitor system health.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If redundant power supplies are used to mitigate loss of power, then reliability is improved, but device complexity and space consumption increase
Solution Approach 1:
The system performs preliminary diagnostic actions by continuously monitoring power supply parameters (temperature, voltage, current, event counts) and storing baseline data in non-volatile memory. This allows the system to detect potential failures before they occur and take preventive measures, reducing the need for complex redundant systems while maintaining reliability.
Solution Approach 2:
The patent implements feedback mechanisms through communication modules that continuously monitor power supply parameters and provide real-time data to the control system. Event flags, event counts, and diagnostic data are fed back to enable proactive maintenance decisions, allowing the system to respond to actual conditions rather than relying on fixed redundancy configurations.
2Reliability
If redundant power supplies are used to mitigate loss of power, then reliability is improved, but space consumption increases
Solution Approach 1:
The power supply system performs self-diagnosis and self-monitoring through integrated sensors and communication modules that track parameters such as temperature, voltage, current, and event counts. This self-service capability allows for early detection of degradation trends, enabling preventive replacement before failure occurs, thereby reducing the need for standby redundant units and optimizing space utilization.
3Ease of repair
If diagnostic data collection is implemented, then maintenance efficiency is improved, but device complexity increases
Solution Approach 1:
The communication module serves multiple functions: it monitors power supply parameters, stores diagnostic data in non-volatile memory, transmits data to the control system, and provides user interface capabilities. This multi-functionality consolidates what could be separate complex components into a single integrated unit, improving maintenance efficiency without proportionally increasing overall system complexity.
