Monitors placed along the conveyor belt detect any rise in CO or combustible gases such as methane as the coal moves along the belt, providing an early warning of potential hazardous conditions. Information is immediately transmitted to an Allen Bradley PLC with a FactoryTalk Software package. On the surface, the operator can clearly locate the problem area, remotely shut down processes in that section, and restart when conditions permit. In this way, monitoring and control capabilities are integrated into one seamless network, enabling personnel tracking and remote of belts, ventilation fans and other processes.
