Image Processing Device Power Controller Deep Sleep Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image processing devices experience reduced power-saving effectiveness due to premature termination of connections with servers when entering deep sleep mode, leading to shorter sleep durations and incomplete power-saving benefits.
Innovation Solution
An image processing device with a power controller and periodic communication managing part that establishes and maintains connections with a server at predetermined intervals, resetting timers to ensure continuous communication and prolong deep sleep mode duration by initiating periodic communications just before entering sleep mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the image processing device enters deep sleep mode to save power, then power consumption is reduced, but the connection with the server is terminated prematurely
Solution Approach 1:
The periodic communication managing part performs preliminary actions by establishing periodic communications with the server just before the device enters deep sleep mode. This ensures the connection is actively maintained and renewed before power is reduced, preventing premature termination while the device is in sleep mode.
Solution Approach 2:
The system implements feedback mechanisms where the power controller monitors the timer measurements and the periodic communication managing part tracks communication status. This feedback loop allows the system to adjust sleep mode entry timing based on connection status, ensuring connections are maintained long enough to be reliable while still achieving power savings.
2Reliability
If the image processing device returns from deep sleep mode immediately to establish periodic communication, then connection maintenance is ensured, but the deep sleep mode duration is shortened
Solution Approach 1:
The system performs the periodic communication establishment action in advance, just before entering deep sleep mode. By doing this preliminary action, the connection is ensured to be maintained without requiring immediate return from sleep mode, thereby maximizing the deep sleep duration while still maintaining connection reliability.
Solution Approach 2:
The system dynamically adjusts the timing of wake-up from deep sleep mode based on the measured time intervals. The power controller uses timer measurements to determine the optimal wake-up time, creating a dynamic schedule that balances connection maintenance requirements with maximum power saving duration.
3Measurement precision
If the timer measures time interval after power supply is stopped, then accurate timing for communication is achieved, but power saving effectiveness is reduced
Solution Approach 1:
The timer measurement is performed as a preliminary action before the device enters deep sleep mode. The periodic communication managing part measures the time interval and uses this information to schedule the next communication, allowing the timer to continue measuring accurately even when power is reduced, thus maintaining timing precision without significantly impacting power saving effectiveness.

AI summary
An image processing device that is capable of executing a job by working together with a server, having: an application that establishes a connection that enables a communication with the server, and establishes periodic communications with the server at predetermined time intervals to maintain the connection; a periodic communication managing part that manages the periodic communication with the server by the application; and a power controller that includes a timer that measures a time elapsed after the application establishes the periodic communication, the power controller starting again a power supply to the application when the timer measures the time interval after the power supply to the application is stopped if a predetermined condition is met. The periodic communication managing part enables the application to establish the periodic communication with the server and resets the measured time before the power supply to the application is stopped by the power controller.
