Detection method of instantaneous coal quantity of belt conveyor based on laser scanning

针对现有井下带式输送机煤量激光仪器检测方式未提出明确激光线提取方法的问题,提出了一种基于激光扫描的带式输送机瞬时煤量检测方法。通过数字摄像仪和激光仪器获取带式输送机上散煤的图像,利用Ohta颜色空间特性提取激光线轮廓,并进行基于索引表的激光线细化和连接处理;根据离线获取的基线和实时获取的激光线,采用梯形面积累积法计算散煤的截面面积,实时获取带式输送机的瞬时煤量。测试结果表明,该方法检测结果与实际煤量匹配,准确性高,实时性好。

In view of problems of high cost,low test efficiency and unable to record test data automatically of functional test methods of existing electro-hydraulic control system of hydraulic support,and in order to verify adaptability of control logic of the electro-hydraulic control system of hydraulic support to working condition of fully mechanized coal mining face,an automatic test platform of electrohydraulic control system of hydraulic support was developed by taking SAC hydraulic support electrohydraulic control system as research object.The test platform uses a test management platform to coordinate multiple test devices to execute test cases collaboratively,adopts simulation technology to simulate data changing process of various sensors,and uses multiple communication networks to real timely collect test data,uses switching of multiple relays to realize multi-function complex.The test platform can realize automatic configuration and management of port function of detection device according to the specific application of fully mechanized coal mining face,and can realize single function test,group function test,automatic following function test and automation adaptability test of working condition of fully mechanized coal mining face,which improves test efficiency and test accuracy,provides an effective means to study adaptability of the electro-hydraulic control system under complex working conditions such as roof caving and floor bump on fully mechanized mining face.
