Machine Automation and Communication

Levels of Automation

Zone-based automation “Navigator 1”

Levels of Automation

State-based shearer automation “Navigator 2”

Levels of Automation

Integrated longwall automation with “Navigator 2 + 3”

Levels of Automation

“Longwall Navigator” for improved face alignment and horizon control

Type

Industry-leading Automation from the Pioneer of State-based Automation.

Type

This shearer has a state-of-the-art distributed automation system for the control, monitoring and protection of the shearer. Its modular design allows it to be configured to meet individual control needs, from basic monitoring and protection to advanced a

Type

The PMC Evo-S control system with state-of-the-art Ethernet communication and backup functionality allows the shearer to be operated even if the overall control system is not functioning.

Type

The shearer is equipped with a state-of-the-art industry PC in a flame-proof housing with plenty of computing power, allowing flexibility to upgrade to future features such as condition monitoring.

Type

A Programmable Logic Controller (PLC) takes care of basic machine control tasks, ensuring that coal is produced.

Type

Unlike competitor systems, the modularity of the longwall system and control allow the longwall to operate in “fault-tolerant” mode, even when there is a problem with the overall automation system.

Type

In other words, integrated automation does not prevent control via individual PLC’s in order to keep production up and running.
