Abstract

This identification apparatus is for identifying the degree of degradation of oil and includes a sensor that detects a substance arising from oil contained in an oil tank and a controller that determines the degree of degradation of the oil based on information related to a substance detected initially by the sensor when the oil is contained in the oil tank in an initial state and on information related to the substance detected subsequently.

First claim

The invention claimed is:

1. An identification apparatus for identifying a degree of degradation of oil contained in an oil tank, the identification apparatus comprising:
a sensor, disposed at a positive distance spaced from the oil tank, that detects gas molecules arising from oil contained in the oil tank; and
a controller configured to execute functions of determining a degree of degradation of the oil based on the gas molecules detected initially by the sensor when the oil is contained in the oil tank in an initial state, and on the gas molecules detected subsequently by the sensor, and outputting a signal containing the degree of degradation, wherein
the gas molecules are aldehyde-based gas molecules or ketone-based gas molecules.

2. The identification apparatus of claim 1 , wherein
the controller is configured to check the gas molecules detected initially as a standard against the gas molecules detected subsequently to determine the degree of degradation of the oil.

3. The identification apparatus of claim 1 , further comprising:
a memory, wherein
data is stored in the memory, the data indicating a correlation between the gas molecules detected by the sensor and the degree of degradation from the initial state of the oil; and
the controller is configured to check the detected gas molecules against the data stored in the memory to determine the degree of degradation of the oil.

4. The identification apparatus of claim 1 , further comprising:
a notification interface, wherein
the controller is configured to provide, upon making a determination that the degree of degradation of the oil exceeds a predetermined threshold, notification of the determination via the notification interface.

5. The identification apparatus of claim 1 , wherein the sensor is disposed in or near an exhaust fan installed above the oil tank.

6. An identification system for identifying a degree of degradation of oil contained in an oil tank, comprising:
a detection apparatus; and
an identification apparatus, wherein
the detection apparatus comprises:
a sensor, disposed at a positive distance spaced from the oil tank, that detects gas molecules arising from oil contained in the oil tank; and
a communication interface configured to transmit information related to the gas molecules detected by the sensor; and

the identification apparatus comprises:
a communication interface configured to receive the information over a network; and
a controller configured to execute functions of determining a degree of degradation of the oil based on the gas molecules detected initially by the sensor when the oil is contained in the oil tank in an initial state, and on the gas molecules detected subsequently by the sensor, and outputting a signal containing the degree of degradation, wherein

the gas molecules are aldehyde-based gas molecules or ketone-based gas molecules.

7. The identification system of claim 6 , wherein
the identification apparatus further comprises a memory;
data is stored in the memory, the data indicating a correlation between the gas molecules detected by the sensor and the degree of degradation from the initial state of the oil; and
the controller is configured to check the detected gas molecules against the data stored in the memory to determine the degree of degradation of the oil.
