Abstract

An abnormality diagnosis device includes a factor-data storage unit that stores therein factor data including a candidate of an alarm-generating factor corresponding to an alarm number; a stored-data storage unit that stores therein, as stored data, statistical data acquired from a statistical data server including the alarm number corresponding to a system configuration number of a servo control device classified based on a system configuration of the servo control device, and a candidate of the alarm-generating factor corresponding to the alarm number, and a generation probability of the candidate; a display unit; and an abnormality-diagnosis processing unit that acquires the alarm number from the servo control device when an alarm is generated, and based on the alarm number, the factor data, and the stored data, adds the generation probability to each candidate and displays, on the display unit, the candidate with the generation probability added.

Claims

1. An abnormality diagnosis device for a servo control device that is connected to the servo control device and a statistical data server, the abnormality diagnosis device comprising:

a factor-data storage unit that stores therein factor data including at least one candidate of an alarm-generating factor corresponding to an alarm number that indicates a type of an alarm in the servo control device and a counter-alarm measure to handle the alarm-generating factor;

a stored-data storage unit that stores therein, as stored data, statistical data acquired from the statistical data server, the statistical data including the alarm number corresponding to a system configuration number of the servo control device classified based on a system configuration of the servo control device, a candidate of the alarm-generating factor corresponding to the alarm number, and a generation probability of the candidate of the alarm-generating factor;

a display unit; and

an abnormality-diagnosis processing unit that acquires the alarm number from the servo control device when an alarm is generated, and based on the alarm number, the factor data, and the stored data, adds the generation probability, a search method for the alarm-generating factor, and the counter-alarm measure to each of the at least one candidate of the alarm-generating factor and displays, on the display unit, the candidate of the alarm-generating factor with the generation probability added.

3. The abnormality diagnosis device according to claim 1, wherein

when a user selects one of candidates of the alarm-generating factor displayed, the abnormality-diagnosis processing unit displays the counter-alarm measure to handle the alarm-generating factor on the display unit and hides rest of the candidates.

4. The abnormality diagnosis device according to claim 1, wherein the stored-data storage unit makes a connection to the statistical data server via the Internet, acquires the statistical data at an arbitrary timing, and updates the stored data with the acquired statistical data.

5. The abnormality diagnosis device according to claim 4, further comprising an accumulated data storage unit that stores therein, as accumulated data, the system configuration number and the alarm-generating factor inputted to the abnormality-diagnosis processing unit by a user and troubleshooting data including the alarm number of an alarm that is cleared by the user when the user clears the alarm generated in the servo control device, and provides the accumulated data to the statistical data server via the Internet at an arbitrary timing.

6. An abnormality diagnosis system comprising:

at least one abnormality diagnosis device for a servo control device according to claim 5; and

the statistical data server that updates the statistical data based on the accumulated data.
