DEVICE FOR DETECTING TRAIN OCCUPIED LINE

摘要

PURPOSE:To ensure the generation of an alarm for all incoming trains in a plurality of track divisions by detecting a train existing on a track between alarm control divisions, when the count value of a start point counter is larger than the counter value of a terminal point counter, and then outputting an alarm issue condition. CONSTITUTION:A start point A is an alarm start point, and the ingress of a train is detected by a closed circuit type start point crossing control element 1. The information of the detection is inputted to a start point counter 2, every time the ingress is detected. The start point counter 2 sends a start point count value alpha to a comparison circuit 3. On the other hand, a terminal point B is an alarm terminal point and an open circuit type terminal point crossing control element 4 detects an outgoing train. This information of the detection is inputted to a terminal point counter, every time the outgoing train is detected. The terminal point counter 5 sends a terminal point count value alpha to the comparison circuit 3. This comparison circuit 3 makes a comparison between the start point count value alpha of the start point counter 2 and the terminal point count value beta of the terminal point counter 5.
