Abstract
One preferable aspect of the present invention is a state detecting system which detects a state of a machine device based on a detection signal from a detecting element provided to the machine device, and is the state detecting system which includes a non-normal time rate detecting unit which detects a rate or a value as a non-normal time rate, the rate being a rate of an integration value of a time during which an amplitude of the detection signal exceeds a predetermined normal amplitude within a predetermined time, and the value being physically equivalent to the rate.
