Abstract

The invention discloses a method for remotely monitoring and controlling a hydraulic support on an underground working surface. A Power Builder platform and an SQL Server database are utilized, and a serial port of a ground industrial personal computer transmits a control parameter or operating command for the hydraulic support by means of an MODBUS protocol to an underground end head controller and an underground hydraulic support controller and receives feedback information; by utilizing a Power Builder control event, the remote tracking and display of an underground coal-winning machine is realized and the remote real-time data and state of the hydraulic support are remotely displayed on the ground industrial personal computer in forms of graphs, curves and tables; by utilizing the function of the Power Builder of quoting external events OLE and OLE Database Blob, the real-time graph processing is realized; the actions of the hydraulic support are controlled on the ground industrial personal computer according to the real-time position of the coal-winning machine on the underground working surface and the real-time state of the hydraulic support, which are analogically displayed on the ground industrial personal computer; and the hydraulic support on the underground working surface automatically tracks the position of the coal-winning machine to carry out machine-following action according to the control parameter sent by the ground industrial personal computer.

Description

technical field [0001] The invention relates to a monitoring and control method of a hydraulic support, in particular to a method for realizing remote monitoring and control of a hydraulic support on an underground working face of a coal mine. technical background [0002] The electro-hydraulic control system of the hydraulic support in the coal mine underground working face is a distributed control system. The existing electro-hydraulic control systems of the hydraulic support include: PM4 of DBT Company, PM31 of MARCO Company and RS20 type of JOY Company, etc. The PM frames are interconnected through BIDI Bus to form a fully mechanized mining face network to control hydraulic supports. The disadvantage of this control method is that once the controller fails to work normally, it will cause the communication interruption of the control system. The communication between PM31 racks is through BIDI Bus, and the interconnection of the whole work surface is through T Bus. The ...
