Voice Pattern Fuel Pump Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing forecourt fuel systems are cumbersome and insecure, requiring manual activation of fuel pumps through physical interfaces, which can lead to inefficiencies and unauthorized fuel dispensing.
Innovation Solution
Implementing a system that uses audible commands to control fuel pumps, where voice patterns are matched against stored patterns in a database to authorize and control fuel pump operations, enhancing both efficiency and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual activation through physical interface is used, then security can be maintained, but operation efficiency deteriorates and unauthorized access becomes possible
Solution Approach 1:
The patent replaces the mechanical physical interface with an acoustic field-based voice recognition system. The forecourt controller captures voice commands through a microphone, processes them to identify fuel pump activation requests, and controls the pumps accordingly. This substitution eliminates the need for manual physical interaction while maintaining security through voice pattern verification.
2Reliability
If physical interface is used for fuel pump activation, then system simplicity is maintained, but security deteriorates allowing unauthorized access
Solution Approach 1:
The patent introduces a voice recognition system as an intermediary between the user and the fuel pump control. The forecourt controller captures voice commands, verifies the user's identity through voice pattern matching against stored patterns in a database, and only then activates the fuel pump. This intermediary layer provides security without requiring complex access control mechanisms.
3Loss of time
If manual entry of fuel dispensing process is required, then system security is maintained, but time consumption increases during busy periods
Solution Approach 1:
The patent enables self-service operation where the user directly communicates fuel pump activation requests through voice commands without requiring manual entry or assistance from station attendants. The voice recognition system automatically processes the commands and controls the fuel pumps, significantly reducing service time during busy periods while maintaining security through voice pattern verification.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system allows for quicker and more efficient fuel dispensing while ensuring only authorized users can operate the fuel pumps, thereby improving security and reducing the risk of unauthorized access.
Implementation Method 1
The voice recognition controller is configured to compare the voice pattern of the audible command word to a plurality of stored voice patterns within a database in communication with the forecourt controller
Data Source
AI summary
A method of controlling a fuel pump includes receiving a first set of data characterizing an audible activation word including a first voice pattern. Control of the fuel pump is authorized in response to the first voice pattern matching a stored voice pattern within a database. A second set of data characterizing an audible command word is received, where the audible command word includes a second voice pattern. The fuel pump is controlled based on the audible command word in response to the second voice pattern matching the stored voice pattern within the database.
