Abstract
An analysis device includes a vibration sensor that detects vibration of a machine, a calculation unit that defines a peak value on the basis of a standard deviation of detection data of the vibration sensor, and a wireless communication device that transmits processed data output from calculation performed by the calculation unit.
Claims6
An analysis device comprising:
- a vibration sensor configured to detect vibration of a machine in a x-axis direction, a y-axis direction, and a z-axis direction;
- a calculation unit, implemented using one or more computing devices, configured to determine a peak value based on a standard deviation of data including the detected vibration;
- and
- a transceiver configured to transmit, to a management computer, processed data including the determined peak value to thereby cause the management computer to detect an abnormality in the machine based on the processed data including the determined peak value,
- wherein the calculation unit is configured to determine, as the peak value, an average value of accelerations having absolute values greater than a value obtained by multiplying the standard deviation by a coefficient, with respect to the data including the detected vibration.
