The present invention comprises: a step of operating a compressor for a predetermined operating limit time; a step of periodically detecting the pneumatic output of the compressor; a step of comparing a predetermined threshold value (Pcomp_th) with the pneumatic output; and a step of determining the abnormal state of the compressor when the pneumatic output does not exceed the threshold value during the operating limit time. [Reference numerals] (AA) Start; (BB) End; (S110) End the control of section A; (S120) Compressor operating time [Pcomp_cnt] initialization; (S130) Pressure sensor output > Pcomp-th?; (S140) Perform a main-sequence; (S150) Section A continuous control Pcomp_cnt variable count increase; (S170) Diagnose abnormal operation of the compressor |
