The “Add a Brain” Solution - The solution I propose is adding a modern intelligent device which interfaces with the ATG which performs two functions:
1. Provides continuous secure remote communication which is used for notifications and configuration. The communications includes secure user authentication and access control as well as logging so that the integrity of the ATG calibration and setup is maintained. The communication uses the “call out” principle and strong point to point encryption which eliminates the need for expensive Internet connections and networking equipment purchase and configuration. Call out technology makes sensor monitoring continuous. It’s low cost and self install makes it suitable and affordable for the 60% of fueling locations managed by “Single Owner Operators” thereby making effective leak detection much more widespread.
2. It includes the ability to create interlock logic using inputs from existing ATG sensors and alarms and remote relay outputs that can be located in the panels where they can easily interlock with pumps and dispensers. This concept avoids the difficulty and expense of hardwiring existing sensors to pumps and dispensers. There is no need to run wires to sensor locations nor deal with the intrinsic safety issues. In addition, the logic in the device can be programmed and monitored remotely and can be overridden remotely by authorized persons in the case of sensor failures. Logging creates an audit trail of what happened when, and who performed the override.
The benefits of this solution are:
Repurposes existing sensors and ATG functions to provide better release detection AND adding interlocks in addition to notification. This flexibility provides the ability to implement future unknown requirements.
Serves the 60% of C-Stores where their lack of an Internet static IP address and their unmanaged local networks makes the serial to Internet convertor method unreliable and expensive to maintain.
Provides secure remote access for security updates and interlock logic programming.
Configuration management ensures calibration and simplifies periodic sensor testing.
Reduces the requirement for training of C-Store staff by moving responsibility to the monitoring and maintenance staff and giving 24x7 protection.
Is expandable, upgradable and low cost.
Simple DIY plug and play installation.
Generates “large data” so that leak detection implementation and effectiveness can be analyzed and improved.
