    摘要： Systems and methods are provided for subway personnel detection. An ultra-wideband (UWB) based detection of objects in subway tunnels may include transmitting UWB signals into an area within a subway tunnel, the area including one or more tracks traversed by trains running in the subway tunnel, receiving UWB signals within the area, and processing received UWB signals to enable detecting objects within the area. The processing may include identifying received UWB signals corresponding to echoes of the transmitted UWB signal transmitted by the detection devices, and detecting based on the echoes of the transmitted UWB signals when an object is present within the area. The object may be assessed, such as to determine when the object represents an intrusion within the area of the subway tunnel.

    摘要： A worker protection system may include a train-mounted unit for use on a train, and one or more wayside units, configured for placement on or near a track traversed by the train. Each of the train-mounted unit and the one or more wayside units may include a corresponding communication component, with one or more antennas, configured to transmit and/or receive wireless signals, with the signals comprise ultra-wideband (UWB) signals, and one or more circuits configured for processing signals and data, and for performing applications or functions relating to operations of the corresponding unit. The train-mounted unit may operate cooperatively with the one or more wayside units, to provide alerts to one or more workers operating on or near the track, based on communication of the UWB signals with at least one of the one or more wayside units.

    摘要： Systems and methods are provided for worker protection. A safety vest may be configured to support worker protection receiver function in worker protection systems. Components used in conjunction with the receiver functions may be integrated into the safety vest. The components may include one or more antennas, radio receiver (or transceiver) circuitry, integrated power supply source, indication components, and acknowledgement components. The safety vest may generate safety alerts in response to receiving signals from peer transmitter devices in the worker protection systems.

    摘要： A collision avoidance system (CAS) is described that includes one or more sensor technologies, including, for example, an Ultra Wideband (UWB) sensing technology. The collision avoidance system is designed to reliably track the location and speed of vehicles and the distance between vehicles over a wide variety of track and terrain. The collision avoidance system may utilize information from a variety of sensor technologies to determine whether one or more vehicles violate speed and/or separation criteria, and may generate a warning.

    摘要： A rail line sensing and safety system adapted to reliably sense the presence, and optionally the direction and speed, of vehicles traveling on a rail line, and when a vehicle is sensed, to indicate whether a safety device, such as crossing gates, lights, bells, etc., should be activated. The system comprises at least one detection module typically mounted on a rail, at least one remote module typically located near a detection module, and at least one control module typically located near a safety device. In operation, a detection module senses a vehicle traveling on a rail line and sends signals to a remote module. The remote module then processes signals received from the detection module and transmits signals to the control module. The control module then directs, either directly or indirectly as a backup or supplement to an existing sensing and safety system, whether a safety device should be activated.
