1. An analysis device comprising:
a vibration sensor configured to detect vibration of a machine;
a microcomputer configured to:
determine an average value of detection data of the vibration sensor in each predetermined cycle interval,
convert a plurality of data points included in each interval to one data point indicating the average value to reduce calculation points, and
perform a vibration analysis with the reduced calculation points, the vibration analysis including performing a Fast Fourier Transform (FFT) with the reduced calculation points;
a power storage configured to provide power to the microcomputer; and
a wireless communication device configured to transmit processed data output from the vibration analysis.
