Development Study of An In-Belt Transducer for Conveyor Condition Monitoring

The principal aim of this 18 month Phase A Research Project was to demonstrate the feasibility of an in-belt transducer system for conveyor belt condition monitoring. This has been successfully accomplished.

Positive results have been achieved with the outcomes summarised as follows:-

1. The in-belt transducer was able to detect the changes of three nominated parameters, ie Idler vibration signature, Idler surface temperature and longitudinal belt tension changes. These three parameters have been selected to characterise the general conveyor condition.
2. A working experimental belt transducer system has been developed and trialed using a time-shared sensor array and a preliminary control and data acquisition system. This preliminary control system included a radio telemetry data transmission system and the software for signal processing of the monitored signals on a remote receiving terminal.

The scene is now set for the next logical phase of work. The feasibility of the method has been demonstrated, but considerable technical challenges remain in the development and design of a working in-belt transducer and data telemetry system suitable for underground deployment and operation.

ACARP has elected to continue to provide part funding for this next stage of the development of the in-belt transducer.
