MOBILE DEVICE FOR DETECTING THE STATE PARAMETERS AND OPERATING PARAMETERS OF VIBRATING MACHINES, VIBRATING MACHINE EQUIPPED WITH SUCH A DEVICE, AND METHOD FOR DETECTING THE OPERATING AND STATE PARAMETERS OF VIBRATING MACHINES
The invention relates to a mobile device for detecting the state parameters and operating parameters of vibrating machines (1), said device having sensor units (26', 26", 26"') and an evaluation unit (29) connected to the sensor units (26', 26", 26"'), wherein the measurement data detected by the sensor units (26', 26", 26"') can be transmitted wirelessly to the evaluation unit (29), and wherein each sensor unit (26', 26", 26"') is equipped with at least three acceleration sensors oriented orthogonally to one another and with an integrated circuit for processing the measurement data detected by the sensor units (26', 26", 26"'). According to the invention, at least four sensor units (26', 26", 26"') form a sensor network, wherein the sensor units (26', 26", 26"') can be releasably fastened to the vibrating machine (1) at a distance from one another with undefined orientation/direction. Furthermore, a local coordinate system X1, Y1, Z1 is defined by the at least three acceleration sensors of a sensor unit (26', 26", 26"'), with the local measurement data detected in a sensor unit (26', 26", 26"') being based on the spatial axes of the coordinate system, and each sensor unit (26', 26", 26"') has a force-of-gravity sensor for detecting the orientation/direction of the local coordinate system X1, Y1, Z1 in space, and the evaluation unit (29) comprises a device for transforming the local measurement data into a superordinate uniform coordinate system X0, Y0, Z0 under consideration of the measurement data of the force-of-gravity sensor.
