基于PLC的液压支架控制系统应用研究

针对薄煤层采煤效率低,煤炭资源严重浪费的问题,并结合中厚煤层开采方法,提出一种十分有效的技术方法.以高可靠性的PLC控制器作为液压支架电液控制系统的控制核心,以CAN总线作为通讯方式,实现液压支架的本架、邻架、隔架控制等.经过反复验证调试证明,以PLC为控制核心的支架控制系统能够可靠的完成支架以及支架之间的基本动作,能够提高工作面推进速度,提高薄煤层工作面的生产效率,提高工作人员的生命安全保障,实现安全可靠生产,以及提高薄煤层综采工作面智能化水平.

The Hydraulic Support Control System Based on PLC Application Research

For thin coal seam mining efficiency is low, the problem of serious waste of coal resources, and combined with thick coal seam mining method, a kind of very effective technology method is put forward. With high reliability PLC controller as the control core of the control system of hydraulic support electro-hydraulic, with Can-bus as the communication methods, implementation of hydraulic support this frame, the adjacent frame, frame control etc. After repeated verification debugging prove to PLC as the control core of stents to fulfill the stents and reliable control system between the basic action, can improve the working face advancing speed, improve the working e~ciency of thin coal seam, improve the staffs life safety, realizing safe and reliable production, and improve the level of intelligent thin coal seam fully mechanized coal face.
