Diagnostic device, sensor data collecting device, diagnostic method, diagnostic program, and diagnostic system

摘要

A reciprocal data acquisition unit (1061) for acquiring forward sensor data and return sensor data including a plurality of sensor data collected at a plurality of data collection positions while the diagnosis target facility is driven back and forth on the same route; Out of the plurality of sensor data included in each of the forward path sensor data and the backward path sensor data acquired by the acquisition unit (1061), the sensor data having the same data collection position is associated with each other, and the forward path sensor data and the backward path sensor data are associated with each other. And an integration unit (1063) for generating diagnostic data for diagnosing abnormality of the equipment to be diagnosed.
