Abstract

This paper proposes a new method of managing train busy through wireless communication without setting up a train detection unit on the ground. The ground device system (30) performs polling communication with the ground device (50) as the master station and the train (2) as the slave station. The ground device (50) stores a list (train list) of train IDs of trains (2) to be managed, and obtains from the train (2) through polling communication with each train (2) included in the train list. Train information including train position information determines the train position of each train (2) included in the train list. In addition, the allowable entry range of each train (2) is calculated to generate travel control information for the train (2), and is transmitted to the train (2) through the polling communication. In addition, by performing handover control of the train (2) as the management target with the adjacent ground device (50), the train (2) entering the wireless communication control area (70) of the ground device (50) is carried out. The train list is updated by adding IDs and deleting train IDs of trains coming out of the wireless communication control area (70) of the ground device (50).

Description

technical field [0001] The invention relates to a ground device for wireless communication with a train. Background technique [0002] In the past, busy detection of trains was carried out by track circuits. In the busy detection by the track circuit, it is possible to always detect whether the train is busy or not on the ground side, but there is a problem that the installation and maintenance of the track circuit take man-hours and costs. [0003] On the other hand, in recent years, a method of busy detection using wireless communication has been proposed. For example, a technique is known in which a train transmits the measured position of its own train to the ground side, whereby the ground side detects that the train is busy (see Patent Document 1). In this patent document 1, a base device is installed in a predetermined section (base point) of the line to detect (manage) the busyness of the train in the base, and by reading the ID from the train passing through the b...
