| description | To provide a method by which a generation or existence of a rail breakage is detected based on the phenomenon that a progress of a train or rail breakage differently influences a level change of a detection signal of a neighboring section in a non-insulated track circuit.SOLUTION: A rail breakage detection device holds reference data K, L, and M each related with level reduction states of a reception level H during a train passing time, for both ends non-insulated sections 13, 14 and so on, detects reduction states (tb) between K and L related with a reception level of each section 13, 14 and so on or a rise state related with M, and determines that rail breakages occur in the non-insulated section, the neighboring sections, and a middle section of three continuous non-insulated sections by comparing those changes with the reference data.SELECTED DRAWING: Figure 1
【課題】無絶縁軌道回路では列車やレール破断の進行状況が隣の区間の検知信号のレベル変化に異なる影響を及ぼすことに基づいてレール破断の発生や存在を検出する。【解決手段】両端無絶縁区間１３，１４，...について列車通過時の受信レベルＨのレベル低下状態に係る基準データＫ，Ｌ，Ｍを保持し、更に各区間１３，１４，...の受信レベルＨに係るＫ，Ｌ間の低下状態（ｔｂ）や、Ｍに係る上昇状態を検出し、それらの変化を基準データに照らして、当該の無絶縁区間や，隣の区間，三連続の無絶縁区間の中間の区間にレール破断が生じたと判定する。【選択図】 図１ |
