Claims
- 1. A method of reducing the shop time of locomotives at a locomotive maintenance facility comprising:providing data gathering systems onboard a locomotive and a computer at a remote locomotive maintenance facility, said computer having a historical data base of locomotive system data on a plurality of similar locomotives, said locomotive system data being selected from the group consisting of ambient air temperature, train notch, total track and force power, total voltage, total amps, software versions, engine RPM, engine temperature, crankcase pressure, dynamic braking, battery voltage, and voltage and amperage for all auxiliary motors; obtaining onboard locomotive systems data with said onboard data gathering systems during operation of said locomotive, prior to arrival of said locomotive at said locomotive maintenance facility for scheduled maintenance; transmitting said onboard systems data via wireless communications to said maintenance facility prior to arrival of said locomotive at said maintenance facility; operating said computer at said maintenance facility, prior to arrival of said locomotive at said maintenance facility, to compare said onboard system data with said historical data base to determine whether any of said onboard system data is out of a predetermined range or is within said predetermined range, but exhibiting a trend toward being out of said range; operating said computer at said maintenance facility, prior to arrival of said locomotive at said maintenance facility, to assign at least one fault code corresponding to at least one system fault based on said onboard systems data being either out of said range or exhibiting a trend toward being out of said range, said at least one fault code being selected from the group consisting of overcurrents, flashovers, crankcase overtemperatures, crankcase overpressures, communication failures, electrical around failures, air conditioner converter failures, propulsion system faults, auxiliary system faults, propulsion motor faults, auxiliary motor faults, auxiliary system charging faults, engine cooling system faults, oil system faults, control wiring faults, and microelectronics faults; and operating said computer at said maintenance facility, prior to arrival of said locomotive at said maintenance facility, to determine any maintenance and repair operations to be performed when said inbound locomotive arrives at said maintenance facility, in response to said at least one fault code.
- 2. The method recited in claim 1, further comprising operating said computer at said maintenance facility, prior to arrival of said locomotive at said maintenance facility, to classify each said maintenance and repair operation into a classification selected from the group consisting of required, advisable, and optional operations.
- 3. The method recited in claim 1, wherein said onboard systems data is determined to be within said predetermined range, but exhibiting a trend toward being out of range by comparing a series of values for a given parameter over a period of time.
- 4. The method recited in claim 1, wherein said historical data base is comprised, at least in part, of data collected from prior downloads of onboard systems data.
