A vehicle-based positioning system (VBPS) for a vehicle traversing a guideway, the VBPS includes an inertial navigation system (INS) on-board the vehicle, wherein the INS is configured to detect inertial parameters of the vehicle while the vehicle traverses the guideway, the detected inertial parameters including roll, pitch and yaw of the vehicle. The VBPS includes a guideway database, wherein the guideway database is configured to store inertial parameters of the guideway at a plurality of locations along the guideway, the stored inertial parameters include roll, pitch and yaw of the guideway. The VBPS further includes a vital on-board controller (VOBC), the VOBC is configured to determine a position of the vehicle based on a comparison of the detected inertial parameters with the stored inertial parameters. The VOBC is configured to limit comparison of the inertial parameters with the stored inertial parameters based on a latest checkpoint passed by the vehicle.

An apparatus for detecting the information about a guideway-guided vehicle having a masking component, the guideway-guided vehicle configured to follow a path of a guideway, comprising a radio frequency identification (RFID) system, method of making, and use thereof are disclosed. The RFID system comprises a first RFID transponder for transmitting, across the path, first RFID transponder specific information. An RFID reader comprises a first antenna for receiving the first RFID transponder specific information. The first RFID transponder and the first antenna are fixed relative to the path and on opposite sides of the path. The RFID reader is configured to substantially continuously monitor the first transponder specific information. The presence of the masking component of the guideway-guided vehicle between the first RFID transponder and the first antenna masks the substantially continuous monitoring of the first RFID transponder specific information.

Disclosed is a railway signaling system for controlling a load. In accordance with the teachings of this invention, the system comprises a first autonomous controller and a second autonomous controller which is redundant with the first controller, each controller connectable to the load such that there is no single point of failure. The first and second controllers operable in either an on-line mode wherein both power outputs provide power to the load or an off-line mode wherein a single power output does not provide power to the load. On-line controllers monitor current therethrough. When both controllers are on-line, the current between the two controller is imbalanced up to a threshold limit, if the threshold limit is exceeded by one controller, that controller will go off line, and if the first controller is off-line and the second controller is on-line, the second controller monitors output voltages of the off-line controller to ascertain that the output voltages are zero.

A train system that includes a plurality of train units including a first train unit and second train unit coupled together. Each first and second train unit includes a controller configured to detect a change in train configuration of the train units, and comprising a plurality of inputs; train integrity signal lines spanning each train unit and coupled with the controller at the plurality of inputs and configured to transmit signals between a front end and a rear end of the train system, the signals indicating a status of train integrity of the train system; and a plurality of relays in communication with the controller, and configured to indicate a coupling or non-coupling status of each train unit.
摘要:
A digital input interface is provided which can be checked for its reliability. The configuration of the circuit on the input side allows a high impedance for a DC input signal and a low impedance for induced AC noise, naturally attenuating any AC induced noise while maintaining the DC input signal. The interface also provides a latent failure detection engine. The latent failure detection engine can open and close an optocoupler on the input side of the interface, which discharges and charges a capacitor on the input side. The time taken for the capacitor to recharge when the optocoupler is re-opened is used to determine if there has been any threshold decay in the interface.

A localization system for a vehicle running on a guideway including portions obscured from satellite view has a number of GNSS receivers placed at strategic locations along the guideway in view of navigation satellites. GNSS transmitters retransmit received GNSS signals along an obscured portion of the guideway. Coded targets are placed at known locations along the guideway. A GNSS receiver on the vehicle picks up GNSS signals directly from the navigation satellites or retransmitted from the GNSS transmitters when on an obscured portion of the guideway. A proximity sensor on the vehicle detects the coded targets. An on-board computer synchronizes the location obtained from the GNSS signals with the location obtained from the proximity sensor. The vehicle is thus able to determine its position even in an obscured portion, such as a tunnel.
