Solution Overview
Problem
Existing terminal apparatuses face reliability issues in data storage due to power outages and voltage drops, leading to incomplete data writing and increased failure probabilities, especially in edge computer gateway applications.
Innovation Solution
A terminal apparatus with a controller that stops power supply to the communication interface during power outages or voltage drops, allowing continued power supply to the storage, ensuring data writing completion and improving reliability by concentrating power consumption on the controller and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power is continuously supplied to all components including communication interface during power outages, then communication functionality is maintained, but power consumption increases and storage writing time is reduced
Solution Approach 1:
The power supply system is segmented into multiple independent power supply units, each dedicated to specific components. The communication interface has its own controllable power supply that can be independently stopped during power outages, while the storage device receives continued power through a separate power supply path. This segmentation allows selective power distribution to prioritize critical functions (storage) over non-critical functions (communication) during power disruptions.
Solution Approach 2:
The power supply system implements dynamic power management by detecting power outage conditions and automatically adjusting power distribution in real-time. When a power outage is detected, the controller dynamically stops power supply to the communication interface while maintaining power supply to the storage device. This dynamic adaptation optimizes power consumption based on actual operating conditions, ensuring critical data writing operations continue even when overall power is limited.
2Duration of action of moving object
If power is stopped to communication interface during power outages, then power consumption is reduced and storage writing time is extended, but communication functionality is lost
Solution Approach 1:
The system segments communication functionality into multiple independent communication interfaces. When a power outage occurs, non-critical communication interfaces can be stopped to save power, while critical communication interfaces that support data writing operations are maintained. This segmentation allows the system to adapt communication capabilities dynamically based on power availability and operational priorities, ensuring data writing continues even when overall communication functionality is reduced.
Solution Approach 2:
The communication interface power supply is made dynamic and controllable, allowing the system to adjust communication functionality in real-time based on power conditions. During power outages, the controller can selectively maintain or stop specific communication interfaces depending on whether they are critical for data writing operations. This dynamic adaptability ensures the system can maintain essential functions while reducing non-essential functions during power disruptions.
3Loss of energy
If power supply to storage is interrupted during voltage drops, then power is conserved, but data writing may be incomplete and storage reliability decreases
Solution Approach 1:
The power supply system is segmented into independent controllable power supply units, with the storage device having its own dedicated power supply path that can be independently controlled from other components. This segmentation allows the storage device to receive continued power during voltage drops through a separate power supply channel, isolating it from power fluctuations affecting other components. The storage power supply can be maintained or restored first during power recovery, ensuring data writing completion while other components experience power interruptions.
Solution Approach 2:
The system implements beforehand cushioning by preparing and maintaining power supply to the storage device as a priority even during voltage drops. The power supply unit for storage is designed to be more resilient and can continue operating or recover faster than other components during power disturbances. This prior preparation and protection of the storage power supply ensures that data writing operations can complete successfully even when overall system power is compromised, cushioning against the harmful effects of power interruptions on data integrity.
Data Source
AI summary
A terminal apparatus includes: a communication interface that acquires data output from a data output apparatus and supplies power to the data output apparatus; a storage that writes the data to a medium; a controller that controls the storage; a power supply that supplies power to the storage; and a power receiver that receives power from an external power source and supplies power to the communication interface and the power supply. In response to detecting a power outage and/or a voltage drop of the external power source, the controller controls the communication interface to stop supplying power to the data output apparatus.
