Belt Spy Monitoring

CBM Beltspy™ is the world's leading conveyor belt inspection and conveyor belt monitoring system utilising machine vision technology for use in surface and underground mines. It is designed to be used during production hours with a full conveyor load. A single workstation, located in an office or control room on the surface, allows the operator to perform an inspection of the covers of all conveyor belts in the mine by visually analysing high resolution images anywhere along the conveyor belts. The system can be configured to inspect either carry or pulley covers, or both.

  • Machine Vision Technology
  • Inspection during production hours
  • Single workstation to handle multiple belts
  • Synchronised view of both sides of the belt
  • Monitoring of fault development
  • Automatic Surface Damage and Joins Detection
  • Instant Visual Access to joins and surface faults
  • Stopping conveyor at predefined position for repair
  • Low cost maintenance
  • Takes full belt image at any time

The system employs proprietary processing algorithms to automatically detect and flag clip joins, splice joins, damaged conveyor belt surfaces and belt edges, collectively called Events. The system maintains precise conveyor belt metrics relative to reference location (RL). The locations of all events (distances from RL) are stored by the system thus providing instant access to event images. Sequential conveyor belt browsing is also available.
The workstation uses a two-monitor configuration:

The left monitor controls system activity and depicts the graphical representation of the conveyor with all events placed on it. The right monitor is dedicated to rendering conveyor belt fragments (about 1m in length) for belt cover sides. 

The operator can also visually compare two images of the same location taken at different times (dates). This allows the operator to analyse historical changes in damage development. The operator can take a full belt image at any time.
The following images represent the monitoring of a deteriorating clip join. The operator is able to use CBM Beltspy to closely monitor the damage and make necessary repairs before catastrophic failure occurs.

Moderate damage - still acceptable      
Image 2   07 Dec
Damage is deteriorating  - requires close monitoring
Image 3   09 Dec
Damage becomes critical - requires immediate repair

Clip Join has been repaired 

The system can be scheduled to automatically stop the conveyor in a particular position, guaranteeing that the location to be repaired will arrive to the assigned repair station.
