UPS Control Device Monitoring Machine State for Safe Shutdown
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing uninterruptible power supply (UPS) devices face challenges in safely managing power failures and voltage fluctuations, leading to data corruption, battery discharge inefficiencies, and potential damage to connected electrical components, as they rely on predetermined time or battery state for shutdown rather than monitoring the operational states of the components.
Innovation Solution
A device and method for UPS that continuously monitors the power supply to machine control components, maintaining power until a specific state change is detected, allowing for controlled shutdown and reducing battery discharge by only supplying power as needed, thus enhancing safety and extending battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If the UPS switches off after a predetermined time or battery state of charge, then the power supply duration is limited, but this leads to data loss and corruption of electrical components
Solution Approach 1:
The control device continuously monitors the operating state of the machine control component and uses this feedback to determine when to switch off the UPS. Instead of using predetermined time or battery state thresholds, the system receives state information from the machine control component and dynamically decides the shutdown timing, ensuring data integrity while optimizing power supply duration.
2Reliability
If the UPS continuously supplies power until a predetermined time, then data loss is prevented, but battery life is reduced due to unnecessary discharge
Solution Approach 1:
The system uses feedback from the machine control component's operating state to determine the exact moment when power supply is no longer needed. The control device monitors when the machine control component has reached a safe state (e.g., data saved, shutdown initiated) and immediately switches off the UPS, preventing unnecessary battery discharge and extending battery life while maintaining data integrity.
3Reliability
If the AEV is used for backup power supply, then power can be maintained after failure, but short-term power failures occur during switchover causing data corruption
Solution Approach 1:
The control device performs preliminary actions by continuously monitoring the operating state of the machine control component before a power failure occurs. When a power failure is detected, the system already has knowledge of the current state and can immediately initiate appropriate shutdown procedures without requiring a switchover to AEV, thereby avoiding short-term power failures and data corruption during transition.
4Device complexity
If the UPS monitors only battery state of charge, then the control mechanism is simple, but switching off at predefined battery levels leads to data loss
Solution Approach 1:
The control device receives feedback not only from battery state monitoring but also from the machine control component's operating state. This dual feedback mechanism allows the system to maintain simple battery monitoring while adding intelligent shutdown control based on the actual state of the protected equipment, preventing data loss without significantly increasing system complexity.
