Method and system for diagnosing machine malfunctions

A system (830) and method (800) for diagnosing a malfunctioning machine. A fault event is selected (806) together with sequential operating parameter data (808) from a selectively focused time interval about the fault event for evaluation of a machine (810). 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 (809) 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 (834). A set of rules (817) or candidate anomalies (841) may be executed over the operating parameter data to further improve the accuracy of the diagnosis.

Autonomous transport system

An autonomous transport system is disclosed, formed by four main subsystems: a channel subsystem; a vehicle subsystem; a wheel guide subsystem and central control station subsystem. The system is designed for the transportation of people or goods, to be used in tall buildings and in small and large scale urban environments. It comprises unitary vehicles that may move in different directions: horizontal, steeply sloped and also vertical tracks, thanks to novel traction wheel assemblies that roll on carefully designed wheel tracks. The system's cabin maintains the horizontal level / position regardless of the changes of track direction or slanting thanks to pendulum based automatic level control and may rotate up to 180° under normal conditions and even a full 360° turn respect to the wheel assembly in space restricted positions. The cabin is mounted on a cantilever, thereby displacing its center of gravity respect of the wheel guides. Thus, a lever action is established, which presses the wheels against the wheel tracks and therefore enough frictional resistance is obtained so as to avoid wheel slippage on the wheel tracks. The vehicles are moved by non-polluting, electric drives that move and stop them with high energy savings. The vehicle runways are designed taking in account safety features against fire hazards. Several vehicles may be used at the same time and on the same track and may run individually or in groups, conforming a train. The system allows for vehicles to be parked in bypassed positions or else they may be disengaged from the convoy to be used individually.

Method of managing interference during delay recovery on a train system

InactiveUS6980894B1Minimizing trip timeAvoiding low train voltageSpeed controllerElectric devicesSystem requirementsLow voltage
The present invention provides methods for preventing low train voltages and managing interference, thereby improving the efficiency, reliability, and passenger comfort associated with commuter trains. An algorithm implementing neural network technology is used to predict low voltages before they occur. Once voltages are predicted, then multiple trains can be controlled to prevent low voltage events. Further, algorithms for managing inference are presented in the present invention. Different types of interference problems are addressed in the present invention such as “Interference During Acceleration”, “Interference Near Station Stops”, and “Interference During Delay Recovery.” Managing such interference avoids unnecessary brake / acceleration cycles during acceleration, immediately before station stops, and after substantial delays. Algorithms are demonstrated to avoid oscillatory brake / acceleration cycles due to interference and to smooth the trajectories of closely following trains. This is achieved by maintaining sufficient following distances to avoid unnecessary braking / accelerating. These methods generate smooth train trajectories, making for a more comfortable ride, and improve train motor reliability by avoiding unnecessary mode-changes between propulsion and braking. These algorithms can also have a favorable impact on traction power system requirements and energy consumption.

Railway locomotive ECP train line control

An interface adaptor is provided between the locomotive MU cable and the ECP trainline permitting ECP data from the lead locomotive to be transmitted via the MU cable on trailing locomotives to a train of ECP cars. On the lead locomotive, the HEU Echelon interface is on a suitable line in the MU cable instead of the separate ECP trainline such the trailing locomotives do not require a separate ECP trainline. The adapter generally employs two transceivers configured as back-to-back repeaters to bridge ECP data between the locomotive MU cable and the ECP trainline. A DC--DC converter can be used to provide the ECP trainline voltage, either as 230 VDC or as a lower voltage. In lower voltage systems the converter may be replaced by a voltage regulator, or may be eliminated. In any case, an inductor is employed on the output to provide a high impedance to the overlay transceiver.
