International Classification:

G06F 1700

US Classification:

701 19, 246169 R, 701 29, 324555

Abstract:

A method and system for predicting failures in a power resistive grid in a vehicle, e. g. , a locomotive, are provided. The method allows for monitoring one or more signals indicative of an estimated grid resistance value. The method farther allows for adjusting the value of the estimated grid resistance relative to a nominal grid resistance value. A comparing step allows for comparing the adjusted value of the grid resistance against the nominal grid resistance value to determine the performance of the respective resistive grid.

702182, 123 4131, 123 4149, 361695

Abstract:

A method and system for identifying or determining degradation in performance of an engine cooling subsystem having an electric motor for powering a fan in a locomotive is provided. The method allows for monitoring a signal indicative of an electrical imbalance in one or more phases in the fan motor of the cooling subsystem, and for adjusting the value of the monitored signal for deviations from an estimated nominal phase signal value due to predetermined external variables so as to generate an adjusted phase signal value. The method further allows for comparing the value of the adjusted phase signal value against the nominal phase signal value to determine the performance of the cooling subsystem.

Abstract:

A system () and method () for diagnosing a malfunctioning machine. A fault event is selected () together with sequential operating parameter data () from a selectively focused time interval about the fault event for evaluation of a machine (). The selectively focused time interval may include data occurring just before, just after, or spanning the fault event. Characterizing information such as slope, rate of change, and absolute sign of the data may be derived () from the operating parameter data over the selectively focused time interval and used in the diagnosis. The fault event and operating parameter data may be compared to existing cases in a case database (). A set of rules () or candidate anomalies () may be executed over the operating parameter data to further improve the accuracy of the diagnosis.

Abstract:

Method and system for processing fault log data from a machine comprising a plurality of respective pieces of equipment are provided. Operational parameter data indicative of operational and/or environmental conditions for the respective pieces of equipment is further processed. The method allows collecting fault log data comprising a plurality of faults from any malfunctioning piece of equipment. The method further allows collecting operational parameter data relatable to each respective time of occurrence of the plurality of faults from the malfunctioning equipment. Respective identifying actions allow identifying a plurality of distinct faults in the fault log data and a plurality of data buckets indicative of respective levels of quantization of each operational parameter. At least one distinct fault cluster is generated from the plurality of distinct faults. Each generated fault cluster is related a respective quantization level of at least one operational parameter to provide at least one fault cluster that may be configurable in at least one of the following cluster configurations: a stand-alone fault cluster configuration and a cluster configuration enhanced with quantized operational parameter data.

International Classification:

F04B 49/03
F04B 49/08

US Classification:

417 12, 417 28, 417 442

Abstract:

A compressed air system, wherein a decision to de-energize a compressor motor is made with consideration of the likely need for the operation of the compressor at a future point in time. A rate of pressure decay in an air reservoir may be extrapolated over a predetermined time period to predict the need for operation of the compressor within the time period. If operation of the compressor is predicted to be needed within the time period, the compressor is allowed to continue to run in an unloaded mode beyond a normal cool down period.

US Classification:

417 42, 417 18, 417 442

Abstract:

A compressed air system and method of operating the system wherein the slip between the compressor motor and its powering alternator is used as an indication of whether the compressor is running in a loaded or unloaded mode. A slip parameter such as % Slip is determined and compared to an allowable value in real time. If the compressor is determined to be erroneously in a loaded mode, a corrective action may be taken to reduce the probability that the motor is later started with the compressor still in the loaded mode.

International Classification:

G08B 23/00

US Classification:

340576, 180272

Abstract:

A system is presented for monitoring an alertness of an operator of a powered system which operates based on a profile. The monitoring system includes a controller to initiate a query to the operator during an operation of the powered system. The query is used to prompt the operator for information related to the operation of the powered system along the profile. The controller compares a response to the query with a correct answer of the query to determine the alertness of the operator.
