全工作面液压支架电液控制系统验证装置研究

Research on verification device for electro-hydraulic control system of hydraulic support in full working face

在分析国内外电液控制系统及其标准,并结合企业科研研发的基础上,构建了三级全工作面液压支架电液控制系统验证测试装置。该装置通过采集电液控制系统在高低温、冷热冲击、高湿、粉尘、酸性、碱性等环境下液压支架执行机构、压力开关、换向阀电磁铁等信号,并基于某工作面真实情况,构建了虚拟仿真和可视化验证测试系统。该系统的建立对标准制修订、智能化工作面和智慧矿山技术的进步具有重要的工程意义。

Based on the analysis of the electro-hydraulic control system and its standards at home and abroad,combined with the research and development of enterprises,a verification testing device for the electro-hydraulic control system of the hydraulic support with three stages in full working face was constructed.The device collected the signals of hydraulic support actuator,pressure switch,reversing valve electromagnet and so on under the environment of high and low temperature,thermal shock,high humidity,dust,acid and alkalinity of the electrohydraulic control system,and then,built a virtual simulation and visual verification testing system based on the real situation of a working face.The establishment of the system had important engineering significance for the seting and revision of standards,and the progress of intelligent working face and intelligent mine technology.
