Ultrasonic Receiver Wake-Up via Bluetooth Signal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In short-distance wireless information transmission using ultrasonic waves, the receiving device's elements such as decoders and acoustic wave receivers are typically in a constant working state, leading to high power consumption, or require manual turning on and off, resulting in poor user experience.
Innovation Solution
The method involves transmitting a Bluetooth wake-up signal from an ultrasonic wave transmitting device to wake up the receiving device only when necessary, allowing the ultrasonic wave receiving device to timely acquire and decode the signal while minimizing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ultrasonic wave receiving device keeps elements (decoders, acoustic wave receivers) in a constant working state to receive ultrasonic data timely, then the reception timeliness is improved, but the power consumption increases significantly
Solution Approach 1:
The system performs preliminary actions by establishing Bluetooth connection and exchanging wake-up signals before ultrasonic data transmission. The receiving device prepares its ultrasonic reception elements in advance through Bluetooth-triggered wake-up, ensuring timely reception without maintaining constant working state. This preliminary preparation resolves the contradiction by activating components only when needed rather than continuously.
Solution Approach 2:
The system implements periodic action through on-demand activation of ultrasonic reception elements. Instead of continuous operation, the receiving device periodically activates its decoders and acoustic wave receivers based on Bluetooth wake-up signals. This periodic activation pattern maintains reception capability while significantly reducing power consumption compared to constant working state.
2Use of energy by moving object
If the ultrasonic wave receiving device is turned on or off manually to reduce power consumption, then the power consumption is reduced, but the user experience deteriorates
Solution Approach 1:
The system implements self-service through automatic wake-up functionality. When a Bluetooth wake-up signal is detected, the receiving device automatically activates its ultrasonic reception elements without requiring manual user intervention. This self-service mechanism resolves the contradiction by eliminating the need for manual on/off operations while still achieving power consumption reduction through selective activation.
Solution Approach 2:
The Bluetooth communication module serves as an intermediary that triggers the activation of ultrasonic reception elements. Instead of direct manual control or continuous operation, the Bluetooth wake-up signal acts as an intermediate trigger that automatically initiates the switching to active state. This intermediary mechanism provides seamless user experience while enabling power-saving operation.
3Reliability
If the ultrasonic wave receiving device remains in a working state all the time to ensure timely reception, then the reception reliability is improved, but the device complexity and power consumption increase
Solution Approach 1:
The system implements dynamics by making the reception elements switchable between active and inactive states based on transmission needs. The receiving device dynamically adjusts its operational state through Bluetooth-triggered wake-up, activating ultrasonic components only when data transmission is anticipated. This dynamic state management maintains reception reliability while reducing device complexity and power consumption compared to static continuous operation.

AI summary
An information transmission method, electronic device and storage medium are provided. The method is applied to an ultrasonic wave transmitting device and includes: transmitting (S11, S31) a Bluetooth wake-up signal; obtaining (S12, S32) an ultrasonic transmission signal based on information to be transmitted; and transmitting (S13, S33) the ultrasonic transmission signal to an ultrasonic wave receiving device. The Bluetooth wake-up signal is configured to wake up the ultrasonic wave receiving device to receive the ultrasonic transmission signal. In the ultrasonic wave receiving device, such elements as a decoder and an acoustic wave receiver may be in a normally-off state; and when it is needed to transmit information through an ultrasonic wave, the ultrasonic wave transmitting device first transmits the Bluetooth wake-up signal; and upon the reception of the Bluetooth wake-up signal, the ultrasonic wave receiving device wakes up related elements to receive the ultrasonic signal, thereby implementing the information transmission.
