Audio Data Transmission Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current audio-data transmission methods face inefficiencies when multiple electronic devices transmit data simultaneously, leading to data collisions and inconvenience, as users need to manually avoid simultaneous transmission to prevent errors.
Innovation Solution
An audio-data transmission method utilizing frequencies between 18000Hz and 20000Hz, where each device can transmit data sounds and identification sounds simultaneously, with identification sounds indicating the presence of other devices' transmissions, allowing only one device to transmit at a time to prevent collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple electronic devices transmit audio data simultaneously, then data transmission efficiency is improved, but data collision occurs and transmission reliability deteriorates
Solution Approach 1:
The transmitting terminal performs a listening detection before transmitting audio data to determine if other devices are currently transmitting. This preliminary action prevents simultaneous transmission and data collision, ensuring reliable communication while maintaining efficient use of the transmission channel.
2Reliability
If users manually avoid simultaneous transmission to prevent data collision, then transmission reliability is improved, but operation convenience deteriorates
Solution Approach 1:
The electronic device automatically performs listening detection and controls transmission timing without requiring user intervention. The system self-manages collision avoidance by detecting other transmissions and adjusting its own transmission schedule, eliminating the need for users to manually coordinate and improving operational convenience.
3Reliability
If the transmitting terminal listens before transmitting to detect other devices, then data collision is prevented and reliability is improved, but transmission time is increased
Solution Approach 1:
The electronic device performs listening detection at periodic intervals rather than continuously monitoring. This periodic approach maintains reliable collision detection while minimizing the time spent on detection, allowing the device to transmit audio data efficiently during available time slots without excessive delays.

AI summary
An audio-data transmission method for an electronic device is provided. The method includes determining (S500; S506) whether or not a plurality of external data sounds and a plurality of external identification sounds are received. The external data sound and the external identification sound are respectively on a data frequency range and an identification frequency range that is different from the data frequency range. The external identification sound includes N sounds of predetermined frequencies wherein N is a positive integer larger than one. When not receiving the external data sound and the external identification sound simultaneously transmitted by at least one external electronic device, the electronic device transmits (S512) a plurality of data sounds and a plurality of identification sounds. The data sound and the identification sound are respectively within the data frequency range and the identification frequency range. The identification sound includes the sounds of predetermined frequencies.
