US 2019/0170606 A1 · DIAGNOSTIC SYSTEM FOR A CLOSED FLUID SYSTEM

Abstract

A diagnostic system for a closed fluid system is provided. The closed fluid system includes a first fluid subsystem and a second fluid subsystem connected using a valve or valve/actuator. The diagnostic system includes a first sensor disposed in the first fluid subsystem, a second sensor disposed in the second fluid subsystem and a computer. The computer receives first time-ordered fluid level measurements and second time-ordered fluid level measurements from respectively the first sensor and the second sensor and performs a comparison of first fluid level of the first fluid subsystem and second fluid level of the second fluid subsystem. The computer produces a notification indicating a predicted transfer of hydraulic fluid when the first time-ordered fluid level measurements and the second time-ordered fluid level measurements have at least a threshold divergence and outputs the notification for display to a user.

Dependent claims

A diagnostic system for a closed fluid system composed of a first fluid subsystem and a second fluid subsystem connected using a valve, the diagnostic system comprising:

a first sensor disposed in the first fluid subsystem and configured to measure a first fluid level of the first fluid subsystem, and output first time-ordered fluid level measurements corresponding thereto;
a second sensor disposed in the second fluid subsystem and configured to measure a second fluid level of the second fluid subsystem, and output second time-ordered fluid level measurements corresponding thereto;
and
a computer coupled to the first sensor and the second sensor, and configured to:
receive the first time-ordered fluid level measurements and the second time-ordered fluid level measurements from respectively the first sensor and the second sensor;
perform a comparison of the first fluid level with the second fluid level from the first time-ordered fluid level measurements and the second time-ordered fluid level measurements;
produce a notification indicating a predicted malfunction of the valve when, based on the comparison, the first time-ordered fluid level measurements and the second time-ordered fluid level measurements have at least a threshold divergence;
and
output the notification for display to a user.
