MOBILE VIBRATION DETECTING DEVICE AND DETECTING METHOD THEREOF

A mobile vibration detecting device comprising a vibration detecting unit, an analog-to-digital converting unit, a first band-pass filtering unit, a transform calculation module, a RMS transform module, a packet generating module, and a communication/transmission module is provided. The vibration detecting unit is utilized for generating an acceleration analog signal. The analog-to-digital converting unit is utilized for generating an acceleration digital signal accordingly. The first band-pass filtering unit and the transform calculation module are utilized for generating a velocity digital signal accordingly. The RMS transform module receives the acceleration digital signal and the velocity digital signal to generate an acceleration RMS transform data and a velocity RMS transform data accordingly. The packet generating module and the communication/transmission module transmit the above mentioned data for a detecting person standing by the motorized machine to read directly.
