摘要: 针对传统防堆煤磨损尾绳保护装置存在检测范围小、安装位置不易设置、易误动作等问题，设计了一种基于二维激光雷达扫描技术和主动红外对射传感器技术的矿井防堆煤磨损尾绳保护系统。该系统采用2层保护系统结构，当堆煤触及第1层保护系统——二维激光雷达扫描系统时，其输出的测距信息发生变化并上传至上位机，上位机控制报警装置报警并启动第2层保护系统——主动红外对射传感器系统；当堆煤煤位继续增高，触及主动红外对射传感器系统时，其输出的电平信号发生变化并上传至上位机，上位机控制提升机电控系统使提升机停止运行，防止堆煤煤位过高对尾绳造成磨损。现场测试结果验证了该系统的可靠性及实用性。

Abstract: In view of problems of small detection range, difficult installation position setting and easy misoperation existed in traditional protection devices for prevention of coal piling wearing tail rope, a protection system for prevention of coal piling wearing tail rope in mine was designed based on two-dimensional laser radar scanning technology and active infrared radiation sensor technology. The system adopts two layer protection system structure. When coal piling reaches the first layer protection system named two-dimensional laser radar scanning system, ranging information output by the two-dimensional laser radar scanning system changes and is uploaded to upper computer. The upper computer controls alarm device and starts the second layer protection system named active infrared radiation sensor system. When coal piling level increases continuously to reach the active infrared radiation sensor system, level signal output by the active infrared radiation sensor system changes and is uploaded to the upper computer. The upper computer controls electric control system of hoist to stop hoist running, so as to prevent high coal piling wearing tail rope. Field test results prove reliability and practicability of the system. -
