Abstract

A route based analysis system includes, in one version, an infrared spectrometer subsystem configured to produce a spectrum for oil introduced to an oil sample cell. The system displays a route including assets with oil to be inspected. The type of oil used in each asset is determined. For each asset on the route, one or more oil property methods specific to the oil used in the asset are located. The spectrum of each asset'"'"'s oil is analyzed using specific methods in order to produce oil properties.

Claims

1. A route based analysis system comprising:

a device including;

an oil sample cell;

an infrared spectrometer subsystem responsive to the oil sample cell and configured to produce a spectrum for oil introduced to the oil sample cell; and

a processing subsystem responsive to the infrared spectrometer subsystem and operating computer programs which;

display a route stored in a computer memory, including assets with oil to be inspected,

determine the type of oil used in each asset by searching the computer memory,

locate, for each asset on the route, one or more oil property methods specific to the oil used in the asset stored in the computer memory,

locate, for each asset along the route, an alarm set specific to the asset stored in the computer memory,

analyze the spectrum of each asset'"'"'s oil produced by the infrared spectrometer using said one or more stored specific methods producing oil properties after introducing said oil to the sample cell along the route, and

compare the oil properties with the stored alarm set specific to the asset; and

a display for displaying said oil properties and any alarm indications.

2. The system of claim 1 further including locating, for each asset'"'"'s oil, a reference spectrum.

3. The system of claim 2 in which analyzing includes using oil property methods which compare said produced spectrum with said reference spectrum.

4. The system of claim 3 in which different oil property methods cover different spectrum wavelength ranges.

5. The system of claim 4 in which different oil property methods include differently weighted functions.

6. The system of claim 1 in which said oil properties include water content, acidity, soot content, the presence of additives, and/or percent oxidation, and/or combinations of the same.

7. The system of claim 6 in which said properties further include, for select assets, a calculated total acid and/or saponification number.

8. The system of claim 7 in which said oil properties include, for other assets, a total base number.

9. The system of claim 1 in which said sample cell is a flip-top sample cell.

10. The system of claim 1 further including a screen for said displays.

11. The system of claim 1 in which the type of oil used in each asset on the route is stored in the system.

12. The system of claim 1 in which said oil property methods are stored in the system.

13. The system of claim 1 in which said alarm sets are stored in the system.

14. A route based analysis system comprising:

a portable handheld unit including;

an oil sample cell;

a display screen for displaying a route to specific locations of machines or engines;

a spectrometer subsystem including an analyzer for producing a spectrum for oil loaded into the oil sample cell from a machine or engine at a said specific location along the route;

a database with route data, oil property analysis methods and reference spectrums and alarm sets for different types of machines or engines along the route;

the display screen also for displaying oil properties and any alarm indications for the oil loaded into the sample cell from the machine or engine at the said specific location along the route; and

a processing subsystem responsive to the spectrometer subsystem and the database for displaying on the display screen the route and the oil properties and alarm indications for the oil loaded into the sample cell from the machine or engine at the said specific location along the route.

15. The system of claim 14 in which the oil properties displayed include water content, acidity, soot content, the presence of additives, and/or percent oxidation, and/or combinations of the same.

16. The system of claim 15 in which the oil properties displayed further include, for select assets, a calculated total acid and/or saponification number.

17. The system of claim 16 in which the oil properties displayed include, for other assets, a total base number.

18. The system of claim 14 in which the type of oil used in each machine or engine on the route is stored in the database.

19. The system of claim 14 further including a processing subsystem in the portable handheld unit, the processing subsystem configured to:

display the route on the display screen including machines or engines with oil to be inspected,

determine the type of oil used in each machine or engine,

locate, for each machine or engine on the route, one or more of the oil property analysis methods specific to the oil used in the machine or engine,

locate, for each machine or engine along the route, an alarm set specific to the machine or engine,

analyze the spectrum, for each machine or engine'"'"'s oil along the route, using said one or more of the specific oil property analysis methods and producing oil properties after the oil is loaded into the sample cell,

compare the oil properties, for each machine or engine along the route, with the alarm set specific to the machine or engine, and

display on the display screen the oil properties and any alarm indications.
