Title:
SAFETY DEVICE OPERATION NUMBER ESTIMATION METHOD AND SYSTEM FOR THE SAME
Document Type and Number:
Japanese Patent JP2020199876
Kind Code:
A
Abstract:
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
