摘　　要：针对目前主井深指系统无法监测扇形门的开闭状态以及篦子堵煤现象,且紧急情况仅能通过人工报警的问题,提出一种基于视频智能识别的主井扇形门堵煤监测系统。首先提取视频帧并且划定ROI区域并作了相关的图像预处理工作,然后针对扇形门监测、篦子堵煤两个问题利用图像处理方法分别予以解决。为了解决扇形门开闭监测问题,采用混合高斯背景模型识别箕斗扇形门;使用基于标准相关性系数的相似度函数来进行模板匹配。为了解决篦子堵煤监测问题,使用帧差法以及背景差分法,从而确定堵煤占比。最后采用MFC以及OpencV软件库设计了一个实际软件系统界面,在解决上述两个问题的同时,抓拍照片或录制异常视频,从而输出报警信号。设计的主井扇形门与堵煤监测系统是监测主井系统的必要手段,对提升主井运输效率以及安全具有重要意义。Aiming at the problem that the deep finger system of the main shaft cannot monitor the opening and closing state of the fan-shaped door and the phenomenon of grate blocking coal,and the emergency can only be alarm by manual,a fan-shaped door blocking coal monitoring system based on video intelligent recognition was proposed.The system firstly extracted video frame and delimited ROI area and did related image preprocessing work,and then used image processing method to solve the two problems of sector door monitoring and grate blocking coal.In order to solve the problem of monitoring the opening and closing of the fan door,the system adopted the mixed Gaussian background model to identify the skip fan door.A similarity function based on standard correlation coefficients was used for template matching.In order to solve the monitoring problem of grate blocking coal,frame difference method and background difference method was used to determine the proportion of blocking coal.Finally,MFC and OpencV software library were used to design a practical software system interface,which could capture photos or record abnormal videos while solving the above two problems,so as to output alarm signals.The main shaft fan-shaped door and coal blocking monitoring system designed is a necessary means to monitor the main shaft system,which has far-reaching and long-term significance to improve the transport efficiency and safety of the main shaft.
