Abnormality diagnostic system and industrial machinery
First Claim
1. An abnormality diagnostic system that diagnoses a condition of a machine or equipment based upon time series data generated by a sensor attached to the machine or the equipment, comprising:
- a first diagnostic device built in a computer on the machine side; and
a second diagnostic device built in a server that communicates with the first diagnostic device, wherein;
the first diagnostic device diagnoses the time series data generated by the sensor, acquires a first diagnostic result, extracts times series data related to the first diagnostic result according to the first diagnostic result, and outputs the time series data related to the first diagnostic result together with the first diagnostic result; and
the second diagnostic device receives the first diagnostic result and the time series data related to the first diagnostic result from the first diagnostic device, diagnoses the time series data to determine a condition of the machine or the equipment, acquires a second diagnostic result, compares the second diagnostic result with the first diagnostic result, and outputs the second diagnostic result together with the first diagnostic result and a result of the comparison, the result of the comparison being indicative of a diagnostic settings change based on the condition of the machine or the equipment.

Abstract
An object of the present invention is to provide an abnormality diagnostic system that can enhance diagnostic precision even if a computer arranged on the machine side does not have sufficient throughput in diagnosing a condition of a machine or equipment based upon time series data generated by a sensor and can reduce communication capacity because communication data volume decreases and industrial machinery provided with the abnormality diagnostic system. A diagnostic device on the machine side 2 diagnoses time series data generated by a sensor, acquires a primary diagnostic result, extracts time series data related to the primary diagnostic result and outputs it to a diagnostic device on the server side 3 together with the primary diagnostic result, the diagnostic device on the server side 3 diagnoses the time series data, acquires a secondary diagnostic result, and displays the secondary diagnostic result together with the primary diagnostic result. Besides, the diagnostic device on the server side compares the diagnostic results and updates a diagnostic process of the diagnostic device on the machine side 2 when the diagnostic results are different as a result of the comparison.
