Fuel Dispenser Remote Maintenance Mode With Password Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing systems for maintaining fuel dispensers require on-site operators to access and update software, which is challenging for remote locations, leading to higher operational costs and lower service quality.
Innovation Solution
A system that allows a fuel dispenser to enter maintenance mode remotely by using a data processor to determine an authorization password based on dispenser data, with a remote enterprise server generating and verifying a password to enable software updates and maintenance operations without on-site intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If on-site operators are used to perform maintenance and software updates, then the fuel dispenser can be properly maintained, but the operational costs increase and service quality decreases for remote locations
Solution Approach 1:
The fuel dispenser is configured to autonomously enter maintenance mode when specific conditions are met (e.g., nozzle returned, pump off, valve closed), eliminating the need for on-site operator intervention. The system self-authenticates and self-activates maintenance mode based on its own operational state and received authentication credentials.
Solution Approach 2:
A remote authentication system acts as an intermediary between the operator and the fuel dispenser. The system transmits authentication credentials remotely, verifies them against the dispenser's operational state, and triggers maintenance mode activation without requiring physical presence at the dispenser location.
2Reliability
If on-site operators are required to enter maintenance mode, then proper authentication can be ensured, but the time and cost for maintenance operations increase
Solution Approach 1:
The system pre-configures authentication credentials and pre-validates maintenance conditions before maintenance is needed. When maintenance is required, the authentication process is already prepared and can be remotely executed instantly, eliminating the time delay of on-site credential verification and system activation.
Solution Approach 2:
The physical presence and manual authentication process is replaced with an automated electronic authentication system. The system uses electronic communication to transmit credentials, verify authentication status, and activate maintenance mode remotely, substituting the mechanical process of on-site operator intervention with an automated electronic process.
3Ease of operation
If the fuel dispenser allows remote maintenance access, then operational costs decrease and service quality improves, but system security and access control may be compromised
Solution Approach 1:
The system continuously monitors its operational state (nozzle position, pump status, valve position) and uses this feedback to determine whether maintenance mode should be activated. Authentication credentials are only accepted and processed when the system state matches predefined safe conditions, creating a feedback loop that prevents unauthorized or unsafe maintenance access.
Solution Approach 2:
The system changes its security parameters dynamically based on operational conditions. Different authentication requirements and access levels are applied depending on the current state of the dispenser, allowing flexible security control that adapts to the specific maintenance needs and system state rather than using a fixed security protocol.
Data Source
AI summary
Systems and methods are provided for controlling maintenance of a fuel dispenser. In one exemplary embodiment, a system is provided having a fuel dispenser that includes an electronics module having a data processor, a remote enterprise server in communication with the electronics module, and a remote code processor in communication with the remote enterprise server. The data processor is configured to determine an authorization password based on data characterizing the fuel dispenser, to receive a remote password that is generated by the remote code processor based on the fuel dispenser data, to determine that the remote password matches the authorization password, and to cause the fuel dispenser to enter a maintenance mode.
