摘要

it is a mobile device for detecting the status parameters and operating parameters of vibrating machines (1), comprising sensor units (26 ', 26 ", 26"') and an evaluation unit (29) connected to the sensor units (26 ', 26 ", 26"'), where the measurement data detected by the sensor units (26 ', 26 ", 26"') are wirelessly transmitted to the evaluation unit (29) , and where each sensor unit (26 ', 26 ", 26"') is equipped with at least three acceleration sensors orthogonally oriented with each other and an integrated circuit to process the measurement data detected by the sensor units (26 ' , 26 ", 26" '), provided that at least four sensor units (26', 26 ", 26" ') form a sensor network, with the sensor units (26', 26 ", 26" ' ) are securely fixable at a distance from each other with an indeterminate orientation / direction for the vibrating machine (1), and in which a local coordinate system (x1, y1, z1) is defined at least three acceleration sensors from a sensor unit (26 ', 26 ", 26"'), where the local measurement data detected in a sensor unit (26 ', 26 ", 26"') are reported to the spatial geometry axes of the coordinate system, and each sensor unit (26 ', 26 ", 26"') includes a gravity sensor to detect the orientation / direction of the local coordinate system x1, y1, z1 in the space, and where the evaluation unit (29) includes an apparatus for transforming the local measurement data into a uniformly higher coordinate system x0, y0, z0, taking into account the measurement data of the gravity sensor.
