Low Duty Cycle Device Protocol Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Low power, battery-operated wireless communication devices in sleep mode cannot communicate effectively with remote information-processing devices due to power conservation, leading to challenges in transmitting operational status information and receiving downlink messages.
Innovation Solution
A device is adapted to intermittently awaken from a hibernating state in synchronization with a location server to enable communication, allowing for efficient transmission and reception of information through a wireless communication network while minimizing constant power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the device operates in sleep mode to conserve battery power, then power consumption is reduced, but communication capability is lost
Solution Approach 1:
The device implements periodic wake-up cycles where it alternates between sleep mode and active communication mode. The device wakes up at predetermined intervals to check for messages and then returns to sleep mode, enabling communication capability to be periodically available while maintaining low average power consumption throughout operation.
2Speed
If the device wakes up frequently to check for messages, then communication responsiveness is improved, but battery life is reduced
Solution Approach 1:
The device dynamically adjusts its wake-up frequency based on communication needs and battery status. When messages are received or communication activity increases, the device increases wake-up frequency to improve responsiveness. When communication is minimal or battery is low, the device reduces wake-up frequency to extend battery life, creating a dynamic balance between responsiveness and power consumption.
