A system for monitoring conveyor belts is disclosed. The system also includes a transmitter, a receiver and circuitry. The transmitter is configured to direct terahertz radiation towards a conveyor belt. The receiver is configured to measure reflected radiation based on the terahertz radiation. The circuitry is configured to determine belt characteristics of the conveyor belt based on the measured reflected radiation.

Terahertz-based conveyor belt monitoring

A system for monitoring a conveyor belt having magnetically permeable cords, has an AC magnetic field generator for generating an alternating magnetic field to magnetize the cords, in use; a magnetic field sensing unit for sensing the alternating magnetic field provided, in use, by the cords and for providing signals representative of the alternating magnetic field; arid a processor for processing the signals to monitor continuous parts of the cords. The system further has a DC magnetic field generator for erasing an AC field previously generated by the AC magnetic field generator, the AC magnetic field generator being positioned between the DC magnetic field generator and the magnetic field sensing unit. The processor also determines the speed of travel of the belt, and the position in space of a lateral edge of the belt.

Monitoring of conveyor belts

A system for monitoring the condition of a conveyor belt having magnetically permeable cords, has a magnetic field generator for generating a magnetic field to magnetize the cords, in use, a magnetic field sensing unit for sensing the magnetic field provided, in use, by the cords, the sensing unit comprising an array of spaced magnetic field sensors, the spacing of the sensors being sufficiently close to discriminate between adjacent cords. The spacing of the sensors depends on the spacing of the cords, and may be less than half the spacing between cords of a conveyor belt. The sensors may be direction sensitive and the sensors may be oriented in more than one direction, to sense the perpendicular and other components of the magnetic field.

A monitoring system is provided for a moving conveyor belt having a plurality of embedded reinforcing cords and identification tags. A tag reader detects and identifies the identification tags passing by the tag reader while a belt monitor scans the cords to detect a plurality of magnetic reference points and a damage event of at least one cord. A control unit in communication with the belt monitor and the tag reader analyzes the belt monitor to identify the plurality of magnetic reference points and the damage event. The control unit also acquires a belt location on the moving conveyor belt from a belt map based on the detected and identified identification tag and a magnetic reference point from the plurality of magnetic reference points. When a damage event is identified, a location of the damage event is determined by the control unit based on the acquired belt location.

Sensor system for a conveyor belt

A system for monitoring the condition of a conveyor belt having magnetically permeable cords, has a magnetic field generator, a magnetic field sensing unit, and a processor for performing a discrete wavelet transform. The wavelet may be a Morlet waveform. The sensing unit can include an array of spaced magnetic field sensors, and the transform can be performed on signals supplied by the sensors.
