Study On Far Range Watching And Controlling Of Mine Drain System

Coal trade is the pillar industry of our country. The sewerage located in the mine is very important for the normal production. In company with the high-output and high-efficiency development of the coal industry, the security of the mine become the key factors that restrict the production.At present, the most mine drainage devices in inland are controlled traditionally by relays, operated by people, and the states of the devices are watching by man, too. This method, controlling drain-system, are composed by complex circuitry, which have many faults, such as: low automatization extent, poor reliability, weakly quick respond ability, and this status is not match the pace of the coal industry. In this thesis, based on the correlative theory, one set of far-ranging watch and control auto-drainage-system is designed, which is consisted by far-ranging watch and control network and local control system, whose core is PLC(Program Logic Controller).
