The Belt Control System in Mining Fields.pdf

(1) System Structure

The belt control System in coal mining fields performs belt machine control and monitoring ground and underground fields of coal mines. The configuration has flexible and rich I/O ports by adopting PLCs. It is easy to implement various scales and functions based on the industrial Ethernet network between PLCs and control systems.

System programming is very flexible. When the requirements are changed, processes can be changed after re-configuring the system and downloading to the field PLCs.

(2) Requirements of Network

The architecture of network is required to be a ring network, guaranteeing the reliability of the system. Because of environmental factors like dust, humidity and instinct safety, the industrial Ethernet switches are required to be qualified on instinct safety, explosion-proof, corrosion, dust and humidity resistant.

(3) Implementation

Industrial Ethernet switches such as SICOM3000BA, KIEN2000 and KIEN6000 are employed in instinct safety systems.
