Abstract

A system and method monitor operation of a compressor, determine whether the operation of the compressor is outside of a designated range of values, and, responsive to determining that the operation of the compressor is outside of the designated range of values, one or more of (a) prevent communication of a signal to a system controller that controls operation of the compressor, (b) direct a gas from a reservoir to a pressure sensor used by the system controller to determine a gas pressure generated by the compressor, and/or (c) communicate the signal to the system controller that controls operation of the compressor.

First claim

What is claimed is:

1. A method comprising:
monitoring operation of a compressor;
determining whether the operation of the compressor is outside of a designated range of values; and
responsive to determining that the operation of the compressor is outside of the designated range of values,
preventing communication of a signal to a system controller that controls operation of the compressor, and
directing a gas from a reservoir to a pressure sensor used by the system controller to determine a gas pressure generated by the compressor.

2. The method of claim 1 , wherein the system controller deactivates the compressor responsive to the system controller not receiving the signal.

3. The method of claim 1 , wherein the system controller changes the compressor to an unloaded state from a loaded state responsive to the gas directed from the reservoir exceeding an upper pressure threshold.

4. The method of claim 3 , wherein the compressor continues to operate in the unloaded state without increasing the gas pressure in one or more conduits.

5. The method of claim 1 , wherein monitoring the operation of the compressor includes determining one or more of a lubricant pressure, a lubricant temperature, or the gas pressure of the compressor.

6. The method of claim 1 , wherein directing the gas from the reservoir includes increasing a total pressure in one or more conduits above the gas pressure generated by the compressor.

7. The method of claim 1 , wherein preventing communication of the signal to the system controller includes interrupting communication of a speed signal from a speed sensor measuring a speed of the compressor to the system controller.

8. The method of claim 1 , further comprising, while the operation of the compressor is within the designated range of values, preventing flow of the gas from the reservoir to the pressure sensor.

9. The method of claim 1 , wherein determining that the operation of the compressor is outside of the designated range of values includes determining whether the operation of the compressor is outside of a first group of the designated range of values or whether the operation of the compressor is outside of a second group of the designated range of values, and further comprising:
responsive to determining that the operation of the compressor is outside the first group of the designated range of values, directing the gas from the reservoir to the pressure sensor; and
responsive to determining that the operation of the compressor is outside the second group of the designated range of values, preventing communication of the signal from the compressor to the system controller.

10. A system comprising:
an equipment controller configured to monitor monitoring operation of a compressor, the equipment controller configured to determine whether the operation of the compressor is outside of a designated range of values,
the equipment controller configured to (a) prevent communication of a signal from the compressor to a system controller that controls operation of the compressor, and (b) direct a gas from a reservoir to a pressure sensor used by the system controller to determine a gas pressure generated by the compressor responsive to determining that the operation of the compressor is outside of the designated range of values.

11. The system of claim 10 , wherein the system controller deactivates the compressor responsive to the system controller not receiving the signal.

12. The system of claim 10 , wherein the system controller changes the compressor to an unloaded state from a loaded state responsive to the gas directed from the reservoir exceeding an upper pressure threshold.

13. The system of claim 12 , wherein the equipment controller is configured to continue operating the compressor in the unloaded state without increasing the gas pressure in one or more conduits.

14. The system of claim 10 , wherein the equipment controller is configured to monitor the operation of the compressor by determining one or more of a lubricant pressure, a lubricant temperature, or the gas pressure of the compressor.

15. The system of claim 10 , wherein the equipment controller is configured to direct the gas from the reservoir to increase a total pressure in one or more conduits above the gas pressure generated by the compressor.

16. The system of claim 10 , wherein the equipment controller is configured to prevent communication of the signal from the compressor to the system controller by interrupting communication of a speed signal from a speed sensor measuring a speed of the compressor to the system controller.

17. The system of claim 10 , wherein the equipment controller is configured to, while the operation of the compressor is within the designated range of values, one or more of (c) communicate the signal from the compressor to the system controller that controls operation of the compressor or (d) prevent flow of the gas from the reservoir to the pressure sensor.

18. A system comprising:
a compressor configured to be disposed onboard a vehicle and to operate to increase a gas pressure in one or more conduits of the vehicle;
a system controller configured to control operation of the compressor; and
an equipment controller configured to monitor monitoring operation of the compressor, the equipment controller configured to determine whether the operation of the compressor is outside of a designated range of values,
the equipment controller configured to (a) prevent communication of a signal from the compressor to the system controller that controls operation of the compressor, and (b) direct a gas from a reservoir to a pressure sensor used by the system controller to determine a gas pressure generated by the compressor responsive to determining that the operation of the compressor is outside of the designated range of values.

19. The system of claim 18 , wherein the system controller is configured to deactivate the compressor responsive to the system controller not receiving the signal and the system controller is configured to change the compressor to an unloaded state from a loaded state responsive to the gas directed from the reservoir exceeding an upper pressure threshold.

20. The system of claim 18 , wherein the equipment controller is configured to direct the gas from the reservoir to increase a total pressure in one or more conduits above the gas pressure generated by the compressor.

21. A method, comprising:
determining a range of designated values for operation of a compressor using machine learning;
determining whether a monitored or sensed designated value of the operation of the compressor is within the range of designated values; and
responsive to determining that at least one of the monitored or sensed designated values is outside of the one or more designated range,
preventing communication of a signal from the compressor to a system controller that controls operation of the compressor;
directing a gas from a reservoir to a pressure sensor used by the system controller to determine a gas pressure generated by the compressor; and one or both of:
shutting down the compressor; or
switching the compressor to an unloaded state.
