SYSTEM AND METHOD FOR SHORT VEHICLE DETECTION
20230092642 · 2023-03-23 ·

A system and a method automatically detect whether a vehicle entering a track section of a railway network is shorter than a predefined length. The method includes detecting at a time T0 an entry of the vehicle on a first track subsection. From the time T0, the occupancy states of at least a first subsection and a third subsection are determined in dependence on the time. The occupancy state is either “occupied” or “free”. The occupancy states for at least first and third subsections is reported to an evaluation unit at least until the occupancy state of the first subsection is “free”. The reported occupancy states determined for the at least first and third subsections are processed by the evaluation unit, and from a temporal evolution of the occupancy states of the first and third subsections, it is determined whether the entering vehicle is shorter than the predefined length.

SYSTEM AND METHOD FOR VIRTUAL BLOCK OPERATIONAL STATUS CONTROL WITH LONG BLOCK TIME DELAY

A system and method for virtual block operational status control with long block time delay is presented. The present disclosure can advantageously increase the capacity and safety of the existing railroad track infrastructure used by the railroads by determining whether a virtual block is healthy or unhealthy. The long block mode can provide a coarse granularity on the presence of a train. In virtual block mode, the system can implement a finer granularity so the virtual aspects of the sub blocks can be realized. The present disclosure provides a long block mode that can provide the system an opportunity to analyze the potential tradeoffs between granularity and reliability by determining which mode (virtual block or long block) is best utilized in a given situation. The system can operate by default in long block mode and ignore the virtual block capabilities until absolutely needed.

Method and apparatus for generating movement authority for train, train-mounted ATP and ZC

The present invention provides a method and apparatus for generating a movement authority for a train, an ATP and a ZC. The method comprises: acquiring a first distance between a first train and a second train; acquiring, according to the speed information of the second train, a response time required by the second train for running across the first distance; acquiring, according to the speed information of the first train, a second distance across which the first train runs within the response time; and generating a movement authority for the second train according to the first distance, the second distance and a preset safety margin. When the movement authority for the second train is calculated, the actual movement state of the first train is considered, and the first train is no longer set as a stationary obstacle, so that the movement authority is prolonged, the tracking distance may be shortened, the operation efficiency of a line is improved, and the dispatching interval may be shortened to reduce the operation pressure at rush hours.

20210253150 · 2021-08-19 ·

A method and a structure for an Autonomous Train Control System (ATCS) are disclosed, and are based on a plurality of autonomous train control elements that operate independent of each other. An autonomous train control element operates within an allocated track space, and based on predefined rules. Further, autonomous train control elements are paired together to exchange operational data. Pursuant to the predefined rules, an autonomous train control element acquires needed track space from a paired element, and relinquishes track space that is not required for its autonomous operation to a paired element. Further, an autonomous train control element is assigned a priority level with respect to the acquisition/relinquishment of track space.

On-board apparatus and ground system

At an on-board control unit of an on-board apparatus, a coupling detecting unit detects coupling of a failure train with respect to the own train. Then, in the case where detection is performed by the coupling detecting unit, a train occupancy range calculating unit updates train length information using the number of vehicles of the failure train and uses the updated train length information to calculate train occupancy range information. Further, a traveling control unit controls traveling and stop of the own train as a series of coupled trains in the case where detection is performed by the coupling detecting unit.
