るハンチングの検知装置。 A data collector that periodically collects the output signal of the detector, a timer that outputs a trigger signal at regular intervals, and a trigger signal of the timer that receives the output signal of the data collector and the output signal of the timer. A numerical calculator calculates the standard deviation when input, and this number is input as the output signal of the value calculator, subtracts it from a predetermined threshold, and outputs a trigger signal when the threshold is exceeded. 1. A hunting detection device comprising: a comparator that inputs an output signal of the comparator; and a notification device that operates when the trigger signal output from the comparator is input.
