Cylinder failure prediction system and method, and cylinder failure inspection system and method

A cylinder failure inspection system comprising:

• a data acquisition part configured to acquire a plurality of pieces of operation time data for each cylinder of a plurality of cylinders by repeatedly detecting operation times of the plurality of cylinders over an equipment operation elapsed time;
• a degradation index value calculation part configured to calculate degradation index values of a plurality of statistical degradation indexes capable of representing a failure of each cylinder on the basis of the operation time data;
• a determination part configured to:
• rank the degradation index values of the statistical degradation indexes calculated for each cylinder according to a magnitude;
• assign a predetermined score to cylinders of the plurality of cylinders having an upper value, which is greater than or equal to a predetermined range, in the ranked degradation index values;
• and
• determine a failure-predicted cylinder on the basis of a sum of the predetermined scores;
• and
• an inspection part configured to measure an air leak of a cylinder, which is determined as a failure-predicted cylinder by the determination part.

A cylinder failure prediction method comprising:

• acquiring, by a data acquisition part, a plurality of pieces of operation time data for each cylinder of a plurality of cylinders by repeatedly detecting operation times of the plurality of cylinders over an equipment operation elapsed time;
• selecting, by a degradation index value calculation part, a plurality of statistical degradation indexes capable of representing a failure of each cylinder, and calculating degradation index values of the selected statistical degradation indexes on the basis of the operation time data;
• ranking, by a determination part, each of the degradation index values for each cylinder according to a magnitude;
• assigning, by the determination part, a predetermined score to cylinders of the plurality of cylinders having an upper value, which is greater than or equal to a predetermined range, in the ranked degradation index values, and determining, by the determination part, a failure-predicted cylinder on the basis of a sum of the predetermined scores;
• inspecting a cylinder that is determined as a failure-predicted;
• and
• replacing the cylinder in which a failure is found by the inspection.
