MONITORING SYSTEM

原文（中国語）

The invention is directed to a monitoring system () for moving machine parts (), in particular of drilling equipment (), having a sensor device () which comprises a plurality of adjacent sensors (), which at least partially surround the machine part () to be monitored; a reference profile () which is arranged spaced apart from the sensor device (), wherein the sensors () of the sensor device () are each configured to transmit measurement beams (M, M, M, M, M, M) to the reference profile (); and a control device () having an evaluation unit () which is configured to compare the measured values (W, W, W, W, W, W) resulting from the measurement beams (M, M, M, M, M, M) with associated reference measured values (R, R, R, R, R, R) and to determine a measurement span (Δ) therefrom.
