Abnormality judgment system, data transmission and reception apparatus, engine control apparatus and abnormality judgment method

摘要

[Task] Perform stable abnormality assessment and data collection without increasing the processing load of the parent controller. [Approach] An abnormality judgment system 100 that judges an operation abnormality of a motor drive machine 1, wherein the abnormality judgment system 100 controls a servo amplifier 2 that controls a motor 12 driving the motor drive machine 1 based on a motor control command and by comparing the operation data acquired with the control of the motor 12 with stored reference data , an operating abnormality of the engine driving machine can detect, a superordinated controller 3 sending engine control commands to the servo amplifier 2, a data collecting module 5 for sending and receiving reference data and operating data to and from the servo amplifier 2, and an edge server 4 interposed between the data collecting module 5 can transmit and receive reference data and operating data and can detect an operating abnormality of the engine drive machine by comparing the operating data with the reference data.
