Application of Millimeter Wave Radar in Collision Prevention of Coal Winning Machines
The intelligent mining of coal mine fully mechanized working face faces the problem of accurately positioning the relative distance between the cutting drum of the coal winning machine and the hydraulic support support plate,in order to avoid collision during the linkage process between the coal winning machine and the hydraulic support plate.The shortcomings of the current application of 3D millimeter wave radar in the field of coal winning machine collision prevention were analyzed,the idea of applying 4D millimeter wave radar in the field of coal winning machine collision prevention was proposed,and research was conducted on this.The 4D millimeter wave radar system was studied and designed from the perspective of the adaptation between the computing power of the 4D millimeter wave radar and the GB 3836.4 power supply parameter limits for intrinsically safe"ib"equipment.At the same time,based on commonly used radar point cloud preprocessing algorithms,a4D millimeter wave radar point cloud preprocessing algorithm suitable for collision detection of coal winning machines was studied in the special working environment of fully mechanized mining faces,providing basic support for the final development of collision detection devices for coal winning machines based on 4D millimeter wave radar.
