The present invention discloses an unsteady-stage equipment vibration wireless monitoring device comprising wireless revolution speed sensors, wireless vibration sensors, wireless acquisition stations and a remote data server; the unsteady-stage equipment vibration wireless monitoring device operates in the following manner: at beginning moment 0 of one acquisition cycle T, the unsteady-stage equipment vibration wireless monitoring device acquires monitoring information; before moment Tr0, the wireless revolution speed sensor acquires to obtain equipment revolution speed for judgment of hibernation, or corresponding vibration data acquired by the wireless vibration sensor is uploaded, and then the wireless vibration sensor enters a hibernation state; at moment Tr, the wireless device starts again, within moment Tr to moment Tr1, the wireless revolution speed sensor acquires revolution speed, if the revolution speed does not meet revolution speed requirements, a wireless vibration sensor 1 uploads data, or hibernates immediately; if the revolution speed meets the revolution speed requirements, all wireless vibration sensors first collect vibration data, and hibernate immediately without uploading of the vibration data, or upload the vibration data and then hibernate immediately; after a cycle T is completed, the above steps are repeated and recycled to enter next cycle T. The unsteady-stage equipment vibration wireless monitoring device can operate in ultra-low power consumption and can adapt to a variety of working conditions and environment.
