Method for avoiding irregular shutoff of production equipment and system for avoiding irregular shutoff
First Claim
1. A method for avoiding irregular shutoff of a production equipment, comprising:
- measuring regularly time-series data of characteristics of a rotary machine used in the production equipment during a production process;
performing a first real-time analysis on the time-series data so as to obtain first failure diagnosis data;
performing a second real-time analysis on the first failure diagnosis data so as to obtain second failure diagnosis data;
predicting a status of the production equipment using the second failure diagnosis data; and
stopping the production process if it is determined from the predicted status of the production equipment that during the production process the production equipment may have an irregular shutoff, and switching to a purge sequence for directing the production equipment to introduce a gas purge.

Abstract
A method for avoiding irregular shutoff of production equipment, includes: measuring regularly time-series data of characteristics of a rotary machine used in the production equipment running for the production; obtaining first failure diagnosis data subjecting the time-series data to a first real-time analysis; obtaining second failure diagnosis data subjecting the first failure diagnosis data to a second real-time analysis; predicting a status of the production equipment several minutes later using the second failure diagnosis data; and shutting off during a production process if the result of the prediction determines that the production equipment will shut off irregularly, and switching to a purge sequence for conducting a gas purge of the production equipment.

11. A system for avoiding irregular shutoff of a production equipment comprising:
-
a production chamber performing a production process of the production equipment;
a rotary machine processing a load of the production process;
sensors measuring time-series data of characteristics of the rotary machine and outputting the time-series data in real time;
a real-time failure diagnosis module configured to perform a first real-time analysis on the time-series data so as to obtain first failure diagnosis data, to perform a second real-time analysis on the first failure diagnosis data so as to obtain second failure diagnosis data, and to predict future status of production equipment based upon the second failure diagnosis data; and
a real-time controller configured to perform and control the production process, and to direct the production equipment to introduce a purge gas if the real-time failure diagnosis module determines that during the production process the production equipment may have an irregular shutoff. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
