摘要
A method for implementing a centralized control platform of a hydraulic support on a fully mechanized mining working face in underground coal mines, which is used for safety production in the underground coal mines. A Siemens PLC S7-300, a C8051F020 single chip microcomputer, a PowerBuilder tool, an SQLServer database and a multi-protocol communication platform are selected to form the centralized control platform, wherein the PowerBuilder tool is used as a front-end development platform; the Siemens PLC S7-300 and the C8051F020 single chip microcomputer are used as a real-time control platform; the PLC is connected to an electro-hydraulic control system, and a communication protocol thereof is a TCP/IP MODBUS protocol; the PLC acts as a client; the electro-hydraulic control system acts as a server end; an infrared transmission apparatus is mounted on a coal mining machine; a receiving apparatus is embedded into a support controller of the electro-hydraulic control system; and after receiving infrared information, the support controller sends the information to an explosion-proof computer of the electro-hydraulic control system. The method may satisfy control functions required by an unattended or nearly unattended working face; can reliably complete various control functions based on operations of an adjacent support; can remotely transmit various pieces of information to a ground monitoring centre in real time; and can monitor various failures in the coal mining process in real time.
