Abstract

Methods, systems, and devices for managing an end-device connected to a commodity delivery network. One device includes computer-readable medium containing instructions for managing the end-device and a processor for executing the instructions. The instructions include instructions for detecting tampering of the end-device, ignoring the detected tampering when the end-device has been placed in an ignore mode, and automatically disconnecting the end-device from the commodity delivery system based on the detected tampering when the end-device has not been placed in the ignore mode.

Claims

1. A computer-implemented method for managing an end-device connected to a commodity delivery system, the end-device included in an enclosure including a door, the method comprising:

determining, with a network interface controller, if the door is open;

when the door is open, determining, with the network interface controller, if the end device is in an ignore mode;

automatically, with the network interface controller, disconnecting the end-device from the commodity delivery system when the door is open and the end-device is not in an ignore mode; and

maintaining, with the network interface controller, a current operating state of the end-device when the door is open and the end-device is in an ignore mode.

2. The method of claim 1, further comprising:

receiving, at the network interface controller, an “

ignore”

command for the end-device;

placing, with the network interface controller, the end-device in the ignore mode based on the “

ignore”

command;

receiving, at the network interface controller, a “

stop ignoring”

command for the end-device; and

placing, with the network interface controller, the end-device out of the ignore mode based on the “

stop ignoring”

command.

3. The method of claim 1, further comprising:

creating, with the network interface controller, an audit log entry; and

transmitting the audit log entry to at least one back office over at least one communication network,

wherein the audit log includes at least one of a date and a time that the door was open and a data and time of disconnecting the end-device from the commodity delivery network.

4. The method of claim 1, further comprising:

receiving, at the network interface controller, a “

connect”

command for the end-device;

determining, with the network interface controller, if the end-device is in an ignore mode;

automatically, with the network interface controller, connecting the end-device to the commodity delivery system based on the “

connect”

command when the end-device is not in an ignore mode; and

maintaining, with the network interface controller, a current operating state of the end-device based on the “

connect”

command when the end-device is in an ignore mode.

5. The method of claim 1, further comprising:

receiving, at the network interface controller, a “

disconnect”

command for the end-device;

determining, with the network interface controller, if the end-device is in an ignore mode;

automatically, with the network interface controller, disconnecting the end-device from the commodity delivery system based on the “

disconnect”

command when the end-device is not in an ignore mode; and

maintaining, with the network interface controller, a current operating state of the end-device based on the “

disconnect”

command when the end-device is in an ignore mode.

6. The method of claim 1, wherein maintaining, with the network interface controller, the current operating state of the end-device includes maintaining, with the network interface controller, the current operating state of the end-device when the door is open, the end-device is in an ignore mode, and at least one ignore condition is satisfied.

7. The method of claim 6, wherein determining if the at least one ignore condition is satisfied includes determining if the door is open at a time after a predetermined start time.

8. The method of claim 6, wherein determining if the at least one ignore condition is satisfied includes determining if the door is open at a time after a predetermined start time and before a predetermined end time.

9. The method of claim 6, wherein determining if the at least one ignore condition is satisfied includes determining if the door is open at a time within a predetermined duration after a predetermined start time.

10. The method of claim 1, wherein determining, with the network interface controller, if the door is open includes receiving a signal from a door sensor.

11. The method of claim 1, wherein determining, with the network interface controller, if the door is open includes reading a door state set by a meter included in the end-device, wherein the meter receives a signal from a door sensor.

12. A system for managing an end-device connected to a commodity delivery system, the system comprising:

a network interface controller configured to;

determine if a door of an enclosure that includes the end-device is open,

when the door is open, determine if the end-device is in an ignore mode,

automatically disconnect the end-device from the commodity delivery system when the door is open and the end-device is not in an ignore mode, and

maintain a current operating state of the end-device when the door is open and the end-device is in an ignore mode.

13. The system of claim 12, further comprising a door sensor configured to transmit a signal indicating if the door is open or closed.

14. The system of claim 13, wherein the network interface controller determines if the door is open based on the signal transmitted by the door sensor.

15. The system of claim 12, wherein the network interface controller is further configured to receive an “

ignore”

command for the end-device and to place the end-device in the ignore mode based on the “

ignore”

command and to receive a “

stop ignoring”

command for the end-device and to place the end-device out of the ignore mode based on the “

stop ignoring”

command.

16. The system of claim 12, wherein the network interface controller is further configured to create an audit log entry and transmit the audit log entry to at least one back office over at least one communication network, wherein the audit log entry includes at least one of a date and a time that the door was open and a date and a time that the end-device was disconnected from the commodity delivery network.

17. The system of claim 12, wherein the network interface controller is further configured to maintain the current operating state of the end-device when the door is open, the end-device is in an ignore mode, and at least one ignore condition is satisfied.

18. The system of claim 17, wherein the at least one ignore condition includes a start time and the at least one ignore condition is satisfied if the door is open at a time after the start time.

19. The system of claim 17, wherein the at least one ignore condition includes a start time and an end time and the at least one ignore condition is satisfied if the door is open at a time after the start time and before the end time.

20. The system of claim 17, wherein the at least one ignore condition includes a start time and a duration and the at least one ignore condition is satisfied if the door is open at a time within the duration after the start time.

21. A non-transitory computer-readable storage medium including instructions that, when executed by a processor, cause the processor to manage an end-device connected to a commodity delivery system, by performing the steps of:

determining if a door of an enclosure that includes the end-device is open;

when the door is open, determining if the end device is in an ignore mode;

automatically disconnecting the end-device from the commodity delivery system when the door is open and the end-device is not in an ignore mode; and

maintaining a current operating state of the end-device when the door is open and the end-device is in an ignore mode.

22. The device of claim 21, wherein the instructions further include instructions for receiving an “

ignore”

command for the end-device and placing the end-device in the ignore mode based on the “

ignore”

command and instructions for receiving a “

stop ignoring”

command for the end-device and placing the end-device out of the ignore mode based on the “

stop ignoring”

command.

23. The device of claim 21, wherein the instructions for detecting tampering of the end-device include instructions for determining when a door of an enclosure containing the end-device is open.

24. The device of claim 21, wherein the instructions for detecting tampering of the end-device include instructions for receiving a “

disconnect”

command.

25. The device of claim 21, wherein the instructions further include instructions for generating an audit log entry and transmitting the audit log entry to at least one back office over at least one communication network.
