Smart Device Service Selection via Operation Data Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios with multiple smart devices, the simultaneous activation of devices by a user's voice command leads to resource wastage and service interference, as all devices provide services simultaneously, rather than efficiently utilizing a single device for the task.
Innovation Solution
The method involves a first device playing response information upon receiving an awaking word, determining if a second device in the same group is awake, and then transmitting and receiving operation information to identify a target device based on service status, signal-to-noise ratio, and time intervals to determine which device should provide the smart service, thereby avoiding simultaneous service provision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple smart devices are placed in various application scenarios and all devices are awoken by a user's voice command, then the system provides comprehensive service coverage, but service resources are wasted and service interference occurs
Solution Approach 1:
The patent segments the service provision function by introducing a target device selection mechanism. Instead of all awoken devices providing services simultaneously, the system divides the service provision task to a single selected device based on operation information comparison, thereby reducing resource waste while maintaining comprehensive coverage
Solution Approach 2:
The patent implements dynamic target device selection by continuously comparing operation information (such as signal-to-noise ratios and power values) from multiple awoken devices. The device with optimal operation information is dynamically selected to provide service, allowing the system to adapt to changing environmental conditions and device states
2Reliability
If multiple smart devices provide smart services simultaneously to a user, then service availability is increased, but service interference occurs and resource efficiency decreases
Solution Approach 1:
The patent employs feedback mechanisms by having devices transmit operation information to each other and using this information to determine the target device. This feedback loop ensures that only one device provides service at a time, eliminating interference while maintaining high availability through the selection of the most suitable device based on real-time operation information
3Ease of operation
If all awoken devices provide smart services to a user, then service accessibility is improved, but resource consumption increases
Solution Approach 1:
The patent implements self-service by enabling devices to autonomously determine their suitability for providing service through comparing operation information. Each device evaluates its own operation information (signal-to-noise ratio, power value) and the system automatically selects the most appropriate device without requiring user intervention, thereby improving accessibility while reducing overall energy consumption

AI summary
The embodiments of the present disclosure provides a smart service method, apparatus and device, the method includes: a first device plays response information corresponding to an awaking word after receiving the awaking word; when the first device determines that a second device in an awake state exists in a device group that the first device is in, the first device transmits operation information of the first device to the second device, and receives operation information of the second device transmitted by the second device; the first device determines, according to the operation information of the first device and the operation information of the second device a target device from the first device and the second device, where the target device is a device in the device group to provide a smart service. The service resources are economized.
