The time measuring module 882 is configured to measure the duration of the error stored by the error storage module 881, and allows the error index to be calculated according to the error and the duration.

The error index calculation module 883 is configured to calculate an error index indicating the degree of risk of occurrence of a failure according to an error value and a duration, and the error index may be calculated by multiplying the error value and the duration. That is, the error index calculation module 883 calculates a larger error index as the error value is larger and the duration is longer, and the larger the error index, the higher the risk of failure.

The failure prediction notification module 884 is configured to notify the user of a time when a failure is likely to occur, and the failure risk point is predicted according to the error index calculated by the error index calculation module 883 . The failure prediction time according to the error index can be set based on experimental or historical data. For example, the error index is divided into 10 sections, within 1 day for the highest section, 5 days for the second section. It can be provided by predicting a time when the risk of failure is high according to each section of the error index.

Performance degradation end unit 890 does not correspond to failure diagnosis or failure risk prediction, but if the rate of change of error exceeds the grain threshold and continues for more than a set time, the laminating roller 300, PVC film roller 4, or tension maintenance It detects that the operating performance of the roller 400 is being deteriorated, so that it can be alerted. More specifically, in the performance degradation detection unit 890, the error due to the interval range measured by the control unit 830 does not exceed the value determined to be a failure, and is not included in a predetermined range in which the risk of failure is predicted, but the rate of change of the error If it increases rapidly beyond this threshold and the rapid increase continues for more than a certain period of time, it is determined that the performance is being degraded, and countermeasures can be made. The performance degradation diagnosing unit 890 may include a change rate calculation module 891 , a threshold value comparison module 892 , a time measurement module 893 , and a degradation diagnosis module 894 .
