Description

The present invention relates to a closed blockage examination system and a closed blockage examination method.

In order to operate trains safely, an automatic closing method is widely used in which all lines are divided into certain sections and only one train can run in one section. In the automatic closing method, the train is operated by the indication of the traffic light. In the automatic closing system, basically, the section between two adjacent traffic lights is one unit, and it is required that an interval of one unit or more is secured between the preceding train and the continuing train. Therefore, for example, when the preceding train is two or more sections away, the traffic light is blue (progress), when the preceding train is one section away, it is yellow (caution), and when there is a train in the next section. Indicates red (stop). For this reason, the operation interval and operation time of the train change greatly depending on the blockage including the position and the radix of the traffic light.

When constructing a new line, opening a new station, or changing the wiring of a station, it is necessary to consider the closing allocation in consideration of the train operation plan and construction costs. In the block split study, it is necessary to repeat the study of the signal display system and the study of the headway to determine the signal position (block section) that satisfies the target headway. Conventionally, there is a technique capable of determining the position of a signal having an optimum time interval value based on a train operation curve (distance-speed curve) (see, for example, Patent Document 1).
