The Down-hole Power Supply Monitoring System of Coal Industry
The Down-hole Power Supply Monitoring System of Coal Industry.pdf(1) System Structure
The down-hole power supply monitoring system is an integrated monitoring system on the down-hole power supply system. The system consists of a down-hole control center, down-hole substation systems, field control systems and communication network. The Communication network offers stable above-ground to underground communication.
(2) Requirements of Network
Because of power consumption, safety, and power supply demands, besides the general industrial standards, safety or explosion-proof certificates of coal industry are also required for the communication devices.
(3) Implementation
Industrial Ethernet switches such as SICOM3000BA, KIEN2000 and KIEN6000 are employed in the down-hole communication networks. These products have passed safety and explosion-proof certifications, such as MA series certifications.
