PROBLEM TO BE SOLVED: To propose a technology capable of detecting a train in a branch part, without providing an on-rail detection mechanism in the branch part.SOLUTION: An on-rail detection mechanism for detecting on-rail of a train is provided in respective sections of an upward side adjacent part U1 of a branch part C1 and respective sections of a downward side adjacent part D1 of the branch part C1. Whether or not the train exists in the branch part C1 is determined by using an on-rail detection result of the respective sections of the upstream side adjacent part U1, an on-rail detection result of the respective sections of the downstream side adjacent part D1 and the opening direction of the branch part C1. For example, when any of the sections of the upward side adjacent part U1 becomes on-rail when determining that the branch part C1 is a non-on-rail, the branch part C1 is determined as on-rail until the section of becoming the opening direction becomes on-rail among the respective sections of the downward side adjacent part D1 and further becomes the non-on-rail.SELECTED DRAWING: Figure 1 【課題】分岐部に在線検知機構を設けずに、分岐部での列車検知を可能とする技術の提案。【解決手段】分岐部Ｃ１の上り方隣接部Ｕ１の各区間、および、分岐部Ｃ１の下り方隣接部Ｄ１の各区間には、列車の在線を検知する在線検知機構が設けられている。そして、上り方隣接部Ｕ１の各区間の在線検知結果と、下り方隣接部Ｄ１の各区間の在線検知結果と、分岐部Ｃ１の開通方向とを用いて、列車が分岐部Ｃ１に在線しているか否かを判定する。例えば、分岐部Ｃ１を非在線と判定しているときに上り方隣接部Ｕ１の区間の何れかが在線となった場合、下り方隣接部Ｄ１の各区間のうちの開通方向となる区間が在線となって更に非在線となるまでの間、分岐部Ｃ１を在線と判定する。【選択図】図１
