Method and system for monitoring industrial machine

A system for monitoring an industrial machine, comprising:

• measuring
• means for measuring an operating condition of an industrial machine,
• recording means for recording data obtained from measurement by the measuring means as one packet of continuous time-series waveform data, and
• displaying means for processing graphically displaying the waveform data recorded by the recording means;
• transmitting means for transmitting the recorded waveform data to a terminal unit located at a remote point through a communication line to display it on the terminal unit.

A method for monitoring an industrial machine, in which an operating condition of an industrial machine is measured and recorded as a continuous time-series waveform data and said waveform data is processed to be graphically displayed on a screen of a terminal unit;

• wherein an normal condition of the industrial machine is preliminarily recorded as a continuous time-series waveform data and can be graphically displayed on the screen of the terminal unit, and waveform data obtained under a certain operating condition can be compared to the waveform data of the normal condition to grasp a trend of the waveform data of said certain operating condition;
• wherein a presently displayed screen can be switched to a diagnosis guidance screen for diagnosing an abnormal condition of the industrial machine, based on a result of the comparison between the waveform data of the normal condition and the waveform data of the certain operating condition;
• and
• wherein said presently displayed screen can be switched from said diagnosis guidance screen to a screen which designates a position where a failure has occurred.

• recording means for recording data obtained from measurement by the measuring means as continuous time-series waveform data, and
• displaying means for processing and graphically displaying the waveform data recorded by the recording means;
• wherein said displaying means graphically displays a normal condition of the industrial machine which was preliminarily recorded as continuous time-series waveform data so that waveform data obtained under a certain operating condition can be compared to said waveform data of the normal condition to grasp a trend of the waveform data of said certain operating condition;
• wherein said displaying means displays a diagnosis guidance which indicates the cause of an error and a way of tackling it, based on the result of the comparison between the waveform data of the normal condition and the waveform data of the certain operating condition.
