Wake-Up Voice Module for Cross-Device Smart Home Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In smart home systems, users face inconvenience when trying to control devices without carrying a terminal, as they need to physically locate the device or the terminal, limiting convenience and versatility in voice control capabilities.
Innovation Solution
A device control method and apparatus utilizing a target voice module that awakens upon receiving voice information, converts it into control instructions, and communicates with servers to control other devices, integrating Internet of Things (IoT) and voice interaction capabilities, allowing voice control of smart home devices without individual configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users control smart home devices using traditional terminal devices, then device control functionality is achieved, but user convenience deteriorates when the terminal is not carried
Solution Approach 1:
The voice module is designed to perform multiple functions: it can serve as a wake-up trigger, a voice command receiver, and a control instruction transmitter. By making the voice module universal, the system eliminates the dependency on terminal devices and enables control in various scenarios (at home, away from terminal, etc.), thus improving both ease of operation and adaptability
Solution Approach 2:
The voice module automatically processes voice commands and generates control instructions without requiring user intervention to operate a terminal. The system self-services by directly converting voice inputs into device control actions, removing the need for users to manually operate terminals or applications
2Measurement precision
If individual configuration is implemented for each smart home device, then device control precision is improved, but system complexity increases
Solution Approach 1:
The voice module acts as an intermediary that receives voice commands and converts them into standardized control instructions. This intermediary layer abstracts the complexity of individual device configurations, allowing users to issue simple voice commands without needing to understand or configure each device's specific parameters, thus maintaining control accuracy while reducing system complexity
Solution Approach 2:
The system segments the control process into two independent parts: voice recognition (handled by the voice module) and device-specific control logic (handled by the target device). This segmentation allows the voice module to focus on accurate voice-to-instruction conversion while each device maintains its own control logic, reducing overall configuration complexity
3Reliability
If physical proximity to the device is required for control, then control reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The system replaces the mechanical requirement of physical proximity with an acoustic field-based control mechanism. Voice commands can be transmitted through the air without requiring the user to be physically close to the device, substituting the mechanical constraint with an acoustic transmission method that maintains reliability while improving convenience

AI summary
A device control method, includes: in response to determining a target voice module is awakened, a collected first voice information is sent to a first server, the first voice information is configured to convert the first voice information into a first control instruction by the first server and send the first control instruction to a second server, and the first voice information contains information for controlling a second target device (S11); the first control instruction fed back by the second server is received(S12); and the second target device is controlled by using the target voice module or a processor according to the first control instruction, and the target voice module and the processor are equipped in a first target device(S13).
