when the fitted function is continuously decreased to the lower limit value, judging as a working condition two, and at the moment, the equipment running state health evaluation system evaluates that the equipment needs to be maintained;
and the other conditions are working conditions III, at the moment, the equipment running state health evaluation system evaluates equipment faults, and the equipment needs to be checked.
