【摘要】：随着煤矿综采工作面自动化水平的日益提高,实现无人工作面已是综采技术的发展方向和目标。综采“三机”联动过程的自动化是实现无人工作面的前提和基础。目前国内部分煤矿虽实现了一定的跟机自动化功能,但基本采用的是国外自动控制系统,国内技术并不成熟。本文通过分析采煤机、液压支架和刮板输送机的工作原理、联动要求及综采工艺,以某综采工作面设备为研究对象,制定了“三机”联动综采工艺方案,给出了“三机”联动工艺流程;设计了“三机”联动控制系统总体方案,确定了联动过程中需检测的相关参数;基于西门子S7-300 PLC对联动控制器和支架控制器进行了选型设计,选择了联动参数检测传感器,确定了各控制器之间的通信方式,进而构建了系统硬件平台;以工艺流程为依据,在分析“三机”联动关系的基础上,设计了联动控制器和支架控制器的PLC控制软件,利用WinCC组态软件开发了系统监控平台;在仿真软件PLCSIM虚拟的PLC硬件环境下,验证了“三机”联动控制软件的有效性。综上所述,本文根据综采设备参数和综采工艺要求,研究设计了一套较完整的综采“三机”联动控制解决方案,对提高综采工作面自动化水平和实现无人工作面具有积极作用。
[Abstract]:With the increasing automation level of fully mechanized coal mining face, realizing unmanned coal face is the development direction and goal of fully mechanized mining technology. The automation of "three machines" in fully mechanized coal mining is the premise and foundation of realizing unmanned working face. Although some domestic coal mines have realized certain automatic function of following machine, they basically adopt foreign automatic control system, and the domestic technology is not mature. Through analyzing the working principle, linkage requirement and fully mechanized mining technology of shearer, hydraulic support and scraper conveyor, this paper takes the equipment of a fully mechanized mining face as the research object, and formulates the "three machines" linkage mechanized mining technology scheme. The "three machines" linkage process flow is given, the overall scheme of the "three machines" linkage control system is designed, and the relevant parameters to be detected in the linkage process are determined, and the type selection design of the linkage controller and the support controller is carried out based on Siemens S7-300 PLC. The system hardware platform is constructed based on the system hardware platform, which is based on the technological process and the analysis of the relationship between the "three computers", and the communication mode between the controllers is determined by selecting the sensor of the linkage parameter detection, and then the hardware platform of the system is constructed. The PLC control software of the linkage controller and the support controller is designed, and the system monitoring platform is developed by using the WinCC configuration software, and the effectiveness of the "three-machine" linkage control software is verified under the virtual PLC hardware environment of the simulation software PLCSIM. To sum up, according to the parameters of fully mechanized mining equipment and the requirements of fully mechanized mining technology, this paper studies and designs a set of relatively complete solution of "three machines" linkage control in fully mechanized coal mining, which plays an active role in improving automation level of fully mechanized coal face and realizing unmanned working face.
