  • Patent number: 9188632
    Abstract: Electrical faults are detected in electrical distribution systems (EDS) by detection and location of radio frequency (RF) emissions generated by the fault with multiple time-synchronized radio frequency monitors (RFM) distributed about the EDS. The RFMs are coupled to a self-learning, electrical fault monitor (EFM) that characterizes and/or locates electrical faults based on operating state (OS) patterns learned from transmission of test signals generated within the EDS. RF emissions data samples are characterized as safe operation (SO) states or potential electrical faults by accessing a base of stored knowledge concerning fault emission characteristics and/or synchronized time of arrival at each RFM. Information in the base of stored knowledge is updated to include new EDS operating states (OS).

    Abstract: A method of controlling one or more locomotives in a consist includes receiving a command and control signal at a controller associated with one of the one or more locomotives, the command and control signal indicative of a desired performance goal for the consist. Operational characteristics of the one locomotive that are factors in achieving the performance goal for the consist are determined. Operational settings for selected ones of the determined operational characteristics for the one locomotive are selectively designated to achieve the performance goal for the consist. Effects of the selectively designated operational settings for the one locomotive may be implemented through the use of control signals to simulate isolation of the one locomotive without physically switching the one locomotive to an isolation mode.

  • Patent number: 8977414
    Abstract: A train control system of the present invention includes: an on-board device 1 that is mounted on a train and has an vehicle radio set VRS1 capable of performing wireless communication; fixed radio sets (WRS1 to WRS7, and SRS1) that are disposed along the railroad track R and capable of performing wireless communication by a time division multiple access method with the vehicle radio set VRS1; and a ground device 2 that calculates distance from a train A to a stop point before a preceding train B on the basis of the location information of the train A obtained by the wireless communication between the vehicle radio set VRS1 and the fixed radio set. The on-board device 1 generates a stop pattern on the basis of the distance, and performs a travel control so that the train A travels at a speed equal to or less than the stop pattern.

  • Patent number: 8965619
    Abstract: An autonomous transport vehicle for transporting items in a storage and retrieval system is provided. The autonomous transport vehicle includes at least two drive wheels and a controller, where each drive wheel is independently driven and a drive wheel encoder is disposed adjacent each drive wheel. The controller, in communication with the drive wheel encoders, is configured to determine a kinematic state of the autonomous transport vehicle within the storage and retrieval system based on incremental data from the drive wheel encoders only and independent of drive wheel slippage.

  • Patent number: 8942869
    Abstract: A tower control system, under an indexing mode of operation, receives a first signal from rail yard equipment. In response to the first signal, the tower control system establishes a positioning mode of operation. Under the positioning mode of operation, and in response to actuation of an interface of the tower control system, the tower control system sends a second signal to a lead powered rail vehicle of a consist. The second signal includes a first command to adjust a throttle setting of the lead powered rail vehicle, along with a second command to idle a throttle of any remote powered rail vehicle of the consist.

  • Publication number: 20150005988
    Abstract: A traction control system and method are provided for electric vehicles with at least one drive wheel powered by an electric drive motor to maintain optimum maximum traction while the vehicle is driven on the ground. The traction control system includes drive means capable of transmitting torque through a vehicle drive wheel and controllable to move the vehicle over a ground surface. A preferred drive means is an electric motor designed to move the vehicle at desired ground speeds in response to operator input. Operator input requests a desired speed, and the system determines drive wheel torque required to produce the desired speed and provides maximum current to produce maximum torque to drive the vehicle with optimum traction at the desired speed. The system uses constant feedback to find maximum current corresponding to torque required for an inputted speed request to automatically control traction in any electric powered vehicle.

  • Patent number: 8924050
    Abstract: In a railway signalling system which transmits a control order to an on-board signalling system by a trackside signalling system, the on-board signalling system being mounted on a train running on a line and the control order being compliant with a signalling system of the line, the present invention allows the train to run through into lines with different signalling systems using a single on-board signalling system. When the train enters a line with a different signalling system from a current line, the on-board signalling system installs a train control application program compliant with the signalling system of the entering line. Then, the on-board signalling system executes the train control application program, allowing the train to be controlled on the entering line according to a control order created by the trackside signalling system of the entering line.

  • Patent number: 8924048
    Abstract: A method for automatically controlling braking of a powered system or consist includes automatically applying a first degree of braking to a consist during a first time period when a powered unit of the consist is being locally or remotely controlled via an onboard control system in an absence of control inputs from an onboard operator. The first degree of braking is based on a first deceleration force selected so that the consist is slowed in a manner effective to limit a peak deceleration rate experienced by the consist sufficient for reducing unintended movement of at least one of one or more riders or cargo onboard the consist. The method also includes automatically applying a second degree of braking to the consist during a second time period following the first time period.
