A sensor system includes one or more sensors that sense vibrations of a vehicle and one or more processors that can determine a speed of the vehicle and determine whether the vibrations occurring at one or more frequencies of interest (that are based on the speed of the vehicle) indicate damage to a propulsion system of the vehicle. The one or more processors optionally may determine a hunting frequency of a wheel and axle set and/or a lateral acceleration of the wheel and axle set from the vibrations. The one or more processors can determine a conicity of a wheel in the wheel and axle set based on the hunting frequency and/or the lateral acceleration that is determined.

Sensor signal processing system and method

Sensor assembly

A sensor assembly includes a housing extending from an insertion end to an opposite coupling end, from a sensor end to an opposite back end, and from a top end to an opposite bottom end. The assembly also includes a sensor dish outwardly projecting from the sensor end of the housing and configured to hold one or more sensors. The assembly also includes a radio frequency (RF) transparent sensor cap configured to be secured to the sensor dish to secure the one or more sensors within the sensor dish. The housing also can be secured to a vehicle for the sensors to measure operational conditions of the vehicle. The housing of the sensor assembly may be connected to a drive train of the vehicle by inserting a fastener through a channel in the housing and into a jacking hole of the vehicle.

A vehicle sensor system includes a fluid sensor configured to be disposed onboard a vehicle system and at least partially extend into a gearbox of a traction motor of the vehicle system. The fluid sensor is configured to output data representative of an amount of a lubricating fluid in the gearbox. The system also includes a positioning system configured to output data representative of movement or an absence of movement of the vehicle system, and one or more processors configured to determine the amount of the lubricating fluid in the gearbox based on the data that is output by the fluid sensor responsive to the data output by the positioning system indicating that the vehicle system has not moved or has moved by less than a designated distance for at least a designated, non-instantaneous period of time.

Vehicle sensor system

System for determining conicity of a wheel based on measured vibrations

A sensor system senses one or more characteristics of vehicles in a vehicle system with sensors disposed onboard the vehicles and communicate data representative of the one or more characteristics from the sensors to one or more of a controller or a control system of the vehicle system. The data communicated from the sensors onboard the same vehicle can be synchronously communicated with respect to the sensors onboard the same vehicle and asynchronously communicated with respect to the sensors disposed onboard one or more other vehicles in the vehicle system. The systems and methods can direct components disposed onboard a vehicle system to change operations, monitor data output by sensors operatively connected with the components, and determine which of the sensors are operatively connected with which of the components based on the operations of the components that are changed and the data that is output by the sensors.

Sensor system

Systems and methods (e.g., a method for controlling and/or operating a compressor) are provided that includes the steps of monitoring a crankcase pressure of a first compressor; analyzing the monitored crankcase pressure that includes calculating an average of the crankcase pressure over a time period and comparing the average of the crankcase pressure over the time period to a nominal crankcase average pressure; identifying a condition of the first compressor based on the analysis of the monitored crankcase pressure; and adjusting operation of a second compressor to compensate for the first compressor in response to identifying the condition of the first compressor based on the analysis of the monitored crankcase pressure. (The method may be carried out automatically or otherwise by a controller).

System and method for a compressor

A sensor assembly includes one or more accelerometers that generate movement signals indicative of movement of a powered system, a fluid level sensor that generates fluid level signals indicative of an amount of fluid in the powered system, and one or more processors that receive the movement signals and the fluid level signals. The one or more processors also (a) filter at least some of the movement signals based on a speed at which the powered system operates and/or (b) calculate one or more of (1) a statistical measure, (2) a fast Fourier transform (FFT), or (3) a discrete Fourier transform (DFT) of the movement signals. The assembly also includes a first antenna that wirelessly communicates the one or more of the movement signals, the amount of fluid, the statistical measure, the FFT, or the DFT to a remote location.
