Abstract:
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 transmits 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 operation of an adjacent support; can remotely transmit various pieces of information to a ground monitoring center in real time; and can monitor various failures in coal mining process in real time.

Claim (Index 5):
The method for implementing a centralized control platform of a hydraulic support on a fully mechanized mining working face in underground coal mines according to  claim 4 , wherein the control process for realizing automatic machine tracking and frame pulling includes three stages: inspection, judgment and control, wherein the position of the coal mining machine is obtained by one inspection, and a traveling direction of the coal mining machine on the working face is judged by inspecting the position of the coal mining machine twice; the inspection is that the end controller of the end centralized control system accesses each support controller for one time in the form of C8051F020 serial port multi-level communication work every 0.5 s, to collect all of the information of the support controller into the end controller; the judgment is that the end controller firstly judges whether the position of the coal mining machine inspected by the support controller is consistent with the position of the coal mining machine transmitted by the explosion-proof computer or not according to the collected information of the support controller and an infrared position signal of the coal mining machine and a coal mining process stage that are transmitted by the explosion-proof computer through the serial port, if the position of the coal mining machine inspected by the support controller is not consistent with the position of the coal mining machine transmitted by the explosion-proof computer, the end controller gives an alarm and stops operation, and if the position of the coal mining machine inspected by the support controller is consistent with the position of the coal mining machine transmitted by the explosion-proof computer, the end controller proceeds to next control stage, that is, according to coal mining process procedure, transmits commands to related support controllers around the coal mining machine to control corresponding hydraulic supports to operate in accordance with the sequence of frame dropping--bottom lifting--frame pulling--frame raising, to perform machine tracking and frame pulling.
