Zusammenfassung: | To provide a method by which an operation number of a train safety device is estimated without use of a measuring device.SOLUTION: An operation number estimation system stores linkage diagrams, connection diagrams and operation diagrams during past terms. The operation number estimation system specifies each behaviors of safety devices responding to changes (state changes) of train operation states based on the linkage diagrams. Also, the operation number estimation system specifies behaviors of each relays responding to behaviors of the safety devices based on connection diagrams of relay groups controlling behaviors of the safety devices. The operation number estimation system specifies state changes number per day based on the operation diagrams, specifies operation numbers per day based on the state changes number per day and behavior of the safety device responding to the state changes and estimates past operation number of the safety device by multiplying the operation number per day by number of past days. Moreover, the operation number estimation system estimates past operation number of the relays based on estimated past operation number of the safety devices and behaviors of the relays responding to behaviors of the safety devices.SELECTED DRAWING: Figure 7
【課題】列車に関する保安装置の動作数量を、測定装置を用いずに推定する。【解決手段】動作数量推定システムは、過去の期間における連動図表、結線図及び運行図表を記憶している。動作数量推定システム、連動図表に基づき、列車の運行状態の変化(状態変化)に応じた保安装置の各々の挙動を特定する。また、動作数量推定システムは、保安装置の挙動を制御するリレー群の結線図に基づき、保安装置の挙動に応じた各リレーの挙動を特定する。動作数量推定システムは、運行図表に基づき、1日当たりの状態変化の数量を特定し、その数量と、状態変化に応じた保安装置の挙動に基づき、1日当たりの動作数量を特定し、1日当たりの動作数量に過去の日数を乗じることで、保安装置の過去の動作数量を推定する。また、動作数量推定システムは、推定した保安装置の過去の動作数量と、保安装置の挙動に応じたリレーの挙動に基づき、リレーの過去の動作数量を推定する。【選択図】図7 |
