DATA EQUIVALENT SYSTEM FOR TRAIN SCHEDULING, DATA EQUIVALENT METHOD USING THE SAME, EQUIVALENT DEVICE AND SUBSTITUTE EQUIVALENT SOURCE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a data equivalent system for train scheduling reducing reflection identify frequency and re-reflection frequency of a data equivalence of an equivalent end device executing data equivalent direction from an equivalent source device of a central monitoring system, and reducing load of the equivalent source device.SOLUTION: A substitute equivalent device 201 receiving a data equivalent signal from an equivalent source device 100 performs data equivalence of the own device and sends the data equivalent signal to multiple equivalent end devices 401 and 402 connected to the own device, makes administrative information gathering execution states of data equivalence of the equivalent end devices 401 and 402 and sends the administrative information to the equivalent source device 100.SELECTED DRAWING: Figure 1
