  • Patent number: 9651573
    Abstract: The invention relates to a method for controlling the operation of a positioning system (10) of a train, the system (10) including: a toothed tone wheel (12), three sensors (18, 20, 22) for detecting the presence of a tooth, arranged spatially so that six possible and different positions of the wheel (12) may be represented by six possible logic states of the three sensors (18, 20, 22), the six states being different, the method including a step for: detecting states corresponding to the signals delivered by the three sensors (18, 20, 22), comparing the detected states with the values of the six logic states, determining the operating state of the system (10) according to the comparison.

  • Publication number: 20120001029
    Abstract: In a train information display system that displays an operation information on each train in a train, a ground system adds the information on the degree of influence on the passengers of each train to the operation information, and transmits the resultant operation information to a transmission-reception device. A content data server stores in advance, as normal-time display information, at least one of advertisement information and destination guidance information that are to be displayed during normal operations. Instruction output devices instruct content display units to display the operation information and normal-time display information in a display sequence corresponding to the influence information received by the transmission-reception device.

  • Patent number: 8055397
    Abstract: As embodied and broadly described herein the invention includes a system for computing a preferred sequence in which cars in a switching queue of a railway switchyard are to be sequentially switched to classification tracks. The system has a processing entity for determining within a given set of cars at least two possible sequences in which the cars in the set can be switched and applying logic rules for identifying among the sequences a preferred sequence. The system also has an output for releasing data describing the preferred sequence.

  • Patent number: 7805227
    Abstract: A method for tracking assets within a rail yard, the method comprising: creating a track layout database for the rail yard, the track layout database providing a map of rail tracks and switches within the rail yard, wherein the track layout database includes machine readable data identifying discrete locations of the rail tracks and switches of the rail yard, each discrete location corresponding to a geographical position of a portion of a rail track or switch; associating rail yard processing steps with portions of the track layout database; receiving a geographical position signal corresponding to an asset within the rail yard; comparing the geographical position signal to the machine readable data of the track layout database in order to identify the location of the asset within the map; and presenting a graphical representation of the location of the asset on the map along with the yard process steps associated with the track section occupied by the asset, wherein the geographical position signal is recei

  • Patent number: 7069123
    Abstract: A method of locating nodes in train having at least one node per car and includes enabling each node; querying each enabled node to respond during a response interval; disabling each node which responded; and re-querying the enabled nodes until no further responses are received during a response interval. The method further includes disabling the responding nodes before the expiration of the response interval if the interval is under utilized and after the expiration of the response interval if the interval is fully utilized. The method further includes determining the number of responses during a present response interval and setting the length of a subsequent response interval as a function of the determined number of responses. The number of responses may be determined for a whole interval or for a portion of the present response interval, and the length of the subsequent response interval is set based on the response rate determined for the portion of the present response interval.
