Bidirectional Channel Control for DECT IoT Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current DECT systems are primarily used for wireless telecommunications and lack effective bidirectional channel control for remote management of Internet of Things devices, particularly in integrating audio playback and remote management functions.
Innovation Solution
A bidirectional channel control system and method utilizing DECT protocol, incorporating a transmitter, receivers, audio channels, and text message control channels for one-to-one and one-to-many messaging modes to send audio data streams and control commands, enabling device operation control, status querying, and real-time volume adjustment based on environmental noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If DECT systems are used for wireless telecommunications only, then voice transmission quality is maintained, but remote management control function is lost
Solution Approach 1:
The patent extends the DECT system's functionality beyond voice communication to include remote management control of IoT devices. The transmitter and receivers are configured to handle both audio data streams and control commands through the same DECT communication infrastructure, enabling multi-functional operation without requiring separate communication systems.
Solution Approach 2:
The patent segments the control functionality into distinct control commands that can be transmitted through the DECT system. Control commands are separated from audio data streams, allowing independent processing and handling of different types of information through the same physical medium.
2Quantity of substance
If audio data stream is transmitted to multiple receivers, then audio coverage is improved, but control command delivery becomes complex
Solution Approach 1:
The patent separates audio data stream transmission from control command delivery. Audio data can be broadcast to multiple receivers simultaneously, while control commands are transmitted individually to specific receivers as needed. This segmentation allows independent optimization of each communication type.
Solution Approach 2:
The patent implements feedback mechanisms where receivers send status information back to the transmitter. This enables the transmitter to track which receivers are active and respond to control commands, simplifying the management of multiple receivers through automated status monitoring and response coordination.
3Adaptability or versatility
If bidirectional communication is implemented, then remote management capability is improved, but channel control complexity increases
Solution Approach 1:
The patent divides the communication channels into distinct functional streams: audio data streams for media playback and control commands for device management. Each channel type is handled independently by the transmitter and receivers, allowing bidirectional communication without requiring complex integrated control mechanisms.
Solution Approach 2:
The same DECT communication infrastructure and device components are used to handle both audio transmission and control command exchange. The transmitter and receivers are designed to process multiple types of data through unified communication protocols, reducing the need for separate dedicated hardware or complex control logic.
Data Source
AI summary
A bidirectional channel control system, method, device, and non-transitory computer-readable storage medium based on Digital Enhanced Cordless Telecommunications is provided. The system comprises a transmitter, at least one receiver, an audio channel, and a text message control channel. The transmitter is configured to send an audio data stream to the at least one receiver through the audio channel. The transmitter is configured to send a control command to the one receiver through the text message control channel in a one-to-one single-point text message mode, and to receive a feedback result from the one receiver in response to the control command. Alternatively, the transmitter is configured to send a control command to each of the at least one receiver based on DECT protocol through the text message control channel in at least one of a one-to-many broadcast messaging mode and a one-to-one single-point messaging mode, and to receive a feedback result from each of the at least one receiver in response to the control command in the one-to-one single-point messaging mode.
