摘要: 针对固定式摄像仪存在视角范围有限、监控覆盖盲区大,云台摄像仪大范围内监控画面无法同步等问题,分析了薄煤层、中厚煤层和大采高工作面对摄像仪配套的关注点,梳理出比较全面的设计需求。经过视场角分析、主要元部件选型、产品架构规划、电路本安化设计,研制出综采工作面本质安全型多目全景摄像仪。该摄像仪在大采高、中厚煤层和薄煤层工作面分别进行了应用测试,应用测试证明:研制的多目全景摄像仪对于工作面自动化采煤过程中涉及到的敏感区域实现了实时、全覆盖、无死角监控,保证了无人化开采工作面的远程可视化割煤的可靠性和安全性,实现了 “看得清”“看得全”,同时为后续“看得懂”的智能识别研究提供最全面的数据源,为智能化工作面系统配套提供了全新的视频监控技术支持和产品支撑。

Abstract: The real-time video of fully mechanized coal face is the necessary reference information to realize remote visual automatic coal mining. As the video image acquisition equipment, the camera has become the standard configuration of intelligent chemical face. At present, the fixed camera normally used in the working face has limited viewing angle range and large monitoring coverage blind area; Although the pan tilt camera can be rotated to adjust the angle of view, the monitoring pictures cannot be synchronized in a large range, which can not provide real-time and comprehensive video pictures for remote control, and there are certain potential safety hazards. Based on the defects of video monitoring in intelligent chemical working face, this paper analyzes the concerns of camera matching in thin coal seam, medium thick coal seam and large mining height working face, and combs out the relatively comprehensive design requirements. After field angle analysis, main component selection, product architecture planning and circuit safety design, the intrinsically safe multi-objective panoramic camera in fully mechanized mining face is developed, It has a fixed wide-angle monitoring angle of 220 ° horizontally and 90 ° vertically, and the 8million pixel, star level ultra-high definition panoramic picture simultaneously covers the real-time monitoring of the coal wall and the support side environment; The application tests are carried out in the working faces of large mining height, medium thick coal seam and thin coal seam respectively, and the problems existing in the application process are summarized and the follow-up improvement measures are put forward. The application test shows that the developed multi view panoramic camera can realize real-time, full coverage and no dead angle monitoring for the sensitive areas involved in the automatic coal mining process of the working face, ensure the reliability and safety of remote visual coal cutting of the unmanned mining working face, realize "clear" and "complete", and provide the most comprehensive data source for the follow-up "understandable" intelligent identification research, It provides a new video monitoring technical support and product support for the intelligent working face system.
