Sensor system for a conveyor belt
First Claim
1. A method of monitoring a moving conveyor belt in a conveyor belt system, the conveyor belt having a plurality of embedded reinforcing cords and a plurality of identification tags, the conveyor belt system having a tag reader for detecting and identifying the presence of an identification tag from among the plurality of identification tags passing by the tag reader and a belt monitoring system to detect a plurality of magnetic reference points, the method comprising:
- acquiring a belt location on the moving conveyor belt from a belt map based on a magnetic reference point from among the plurality of magnetic reference points as well as a detected and identified identification tag;
scanning the cords of the conveyor belt using the belt monitoring system;
analyzing data from the scanned cords to identify a damage event of at least one cord from among the plurality of cords in the conveyor belt; and
in response to identifying the damage event, determining a location of the damage event based on the acquired belt location.

Abstract
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.
