A belt monitoring system which can accurately monitor the condition of a conveyor belt by correcting it for the effect of belt deviation. Wear detecting magnets (11), which are rubber magnets spanning the entire belt width, are embedded at intervals along the circumferential direction of the conveyor belt (2). Also, position determining magnets (12, 12z) are embedded in positions a predetermined distance apart from the wear detecting magnets (11). In addition, a plurality of magnetic field detecting means (13: 13A-13G) for detecting the magnetic fields from the magnets (11, 12, 12z), which are arranged at predetermined intervals in the width direction of the conveyor belt (2), are disposed in a position spaced apart from the surface of the conveyor belt (2). The state of deviation of the conveyor belt (2) is detected based on the output signals from the position determining magnets (12, 12z) detected by the magnetic field detection means (13), and then the belt thickness distribution of the conveyor belt (2) in the width direction is corrected based on the detected state of belt deviation. |
