Voice control system and method for moving a column
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice control systems for lifting columns often experience unwanted triggering due to shared wake-up words among multiple columns, leading to inconvenient usage and high computational costs for complex semantic matching.
Innovation Solution
A voice control system with a controller, storage module, and voice collection module that allows users to select and display multiple wake-up words, using LED lights for identification, and includes a method for switching wake-up words to prevent unwanted triggering, utilizing a processor that only compares sound wave characteristics without semantic matching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the same wake-up word is used for multiple lifting columns, then the system is simple to operate, but unwanted triggering occurs frequently
Solution Approach 1:
The patent divides the single shared wake-up word into multiple distinct wake-up words, assigning different wake-up words to different lifting columns. This segmentation allows each column to have its own unique identifier, preventing unwanted triggering while maintaining simple voice-based operation.
Solution Approach 2:
Each lifting column is given a unique local characteristic through its own specific wake-up word. This local quality differentiation ensures that the wake-up command for one column does not accidentally trigger another column, resolving the unwanted triggering issue while keeping the system easy to use.
2Measurement precision
If semantic matching is used for voice control, then the control accuracy is improved, but the computational cost and device complexity increase
Solution Approach 1:
The patent extracts the complex semantic matching function from the lifting column controller and relocates it to a remote server. The column only needs to perform simple sound wave characteristic comparison and transmit basic voice data, significantly reducing its computational requirements while maintaining accurate voice control through server-side processing.
Solution Approach 2:
A server acts as an intermediary between the user's voice input and the lifting column control. The server handles the complex semantic matching and control algorithm execution, while the column handles only simple voice collection and basic sound wave comparison, reducing the column's computational burden while maintaining control accuracy.

AI summary
The disclosure relates to the technical field of lifting mechanisms, and in particular to a voice control system and a method for moving columns, comprising a lifting mechanism, a controller, a storage module, and a voice collection module. The lifting mechanism, the storage module and the voice collection module are all electrically connected to the controller. A control word and at least two wake-up words are stored in the storage module. The system further includes a selection module for selecting the wake-up word and a display module for displaying the current wake-up word. Both the selection module and the display module are electrically connected to the controller. The likelihood of unwanted triggering can be decreased by the voice control system and method.
