Rail Vehicle Voice Control With Release Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling rail vehicles require manual entry of control parameters, which is time-consuming and prone to errors.
Innovation Solution
A voice-controlled system that records a voice message from the user containing control parameters, extracts these parameters, displays them, and only applies them to control the rail vehicle after a release command is detected from the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual entry of control parameters is used, then accuracy of parameter entry can be maintained through verification, but input time is excessively long
Solution Approach 1:
The patent replaces the mechanical manual entry system (keyboard input, button pressing) with an acoustic recognition system. The voice recognition device captures spoken commands and converts them into control parameters, eliminating the need for manual typing or button pressing. This substitution dramatically reduces input time while maintaining ease of operation through natural speech.
Solution Approach 2:
The patent introduces an acoustic recognition system as an intermediary between the user's intent and the control system. The voice recognition device acts as a mediator that translates spoken language into machine-executable commands, reducing the complexity of direct manual entry while ensuring accurate parameter transmission to the control system.
2Productivity
If voice control is implemented, then input time is reduced and ease of operation is improved, but reliability may be compromised due to potential recognition errors
Solution Approach 1:
The patent implements a feedback mechanism where the control system receives and processes voice commands, then provides status information back to the user. The control system can confirm received parameters, request clarification for unrecognized commands, and provide feedback on system state, allowing the user to verify that voice commands were correctly interpreted and executed.
Solution Approach 2:
The patent prepares the control system in advance to handle potential recognition errors by implementing error tolerance mechanisms. The system is designed to manage unrecognized commands, request rephrasing, and validate parameters before execution, cushioning against the reliability risks of voice recognition without requiring manual verification of each parameter.
3Adaptability or versatility
If multiple control parameters are entered manually, then precise control is achieved, but the complexity of the operation increases significantly
Solution Approach 1:
The patent makes the voice recognition device universal by enabling it to recognize and process multiple different control parameters through a single interface. The system can handle various command types (speed control, direction, temperature, etc.) and multiple parameters simultaneously through natural speech, eliminating the need for separate manual entry procedures for each parameter type.
Solution Approach 2:
The patent merges the entry of multiple control parameters into a single unified voice command interface. Instead of requiring separate manual entry for each parameter, the system combines multiple parameter inputs into integrated voice commands, reducing operational complexity while maintaining the ability to control all system aspects.
Data Source
AI summary
A method for controlling a rail vehicle includes recording a voice message of an user of the rail vehicle which contains a control parameter for controlling the rail vehicle. The control parameter is extracted from the recorded voice message. The extracted control parameter is displayed and the rail vehicle is controlled on the basis of the extracted control parameter only upon detection of a release command of the user that the extracted control parameter may be used for controlling the rail vehicle.
