The intrinsically safe Cat® PMC-R 2.0 control units are specifically designed to be used on shearer or plow faces to provide high levels of longwall automation. Each roof support is equipped with one PMC-R 2.0 control unit and solenoid driver to operate the in-shield hydraulic functions and peripheral components, such as sensors for cylinder pressure and stroke length, shield inclination and personnel proximity detection. The PMC-R 2.0 unit controls and displays all functions of a roof support and serves as the interface between operator and machine (HMI).
Features At A Glance
INTERACTIVITY
This interactive system allows users to execute single shield and automatic functions, as well as perform remote control operations from anywhere in the mine including the surface. To provide feedback for the operator on the longwall, important process values are continuously displayed on a full-color display.
HIGH-SPEED DATA TRANSMISSION
The PMC-R 2.0 control unit delivers fast 100M/Bit Ethernet communication, enabling real-time system feedback and data refresh rates for remote control operation. The low latency connection also means process data values are updated much faster for higher resolution when data logging and reviewing historical trending. An enhanced user experience is provided when viewing Cat 3D VSoftware applications as the data is refreshed at a higher frequency resulting in a smoother and more accurate representation of the equipment underground.
ADVANCED FUNCTIONALITIES
The high bandwidth connection enhances machine-to-machine integration which provides for advanced automation functionality. More complex messages can be exchanged between the equipment, creating holistic integration and interoperability resulting in increased performance and reliability.
