摘要:

为了实现在选煤厂中长距离、高效率、低费用运输,钢丝绳芯胶带输大量使用,从而钢丝绳芯输送带横断检测技术成为选煤厂的难题,减少人为观测误差,采用X射线原理高速无缝采集透视装置,建立了钢丝绳芯输送带运行状态下的在线检测系统,实现了输送带钢丝绳芯出现损伤的对比分析和实时报警;采用高速AD采样转换电路,配合FPGA时钟电路实现了X射线检测数据和信息的连续、高速拍摄、透视和成像分析,并实现了检测数据高速远距离传输;采用图像识别技术对输送带内部钢丝绳的接头抽动、断绳、断丝、锈蚀等损伤状况进行准确直观的判断,并自动生成检测报告,具备了自动记录和无人值守功能。从而确保了选煤厂钢丝绳芯输送带安全高效运转。

Abstract:

In order to achieve the long-distance, high efficiency and low-cost transportation in the coal preparation plant, use the steel wire rope core belt transmission widely, so that the steel cord conveyor belt the Heng duan detection technology to become the problem of the coal preparation plant, reducing human observation error, I will use high-speed seamless acquisition perspective device , establish a steel cord conveyor belt running state line detection system, achieve the comparative analysis of the conveyor belt steel cord injury and real-time alarm. Through using high-speed AD sampling conversion circuit and the FPGA clock circuit to achieve X-ray detection data, information of continuous, high-speed shooting and imaging analysis, I can inspect high-speed and long-distance data transmission. Through using image recognition technology twitching on the conveyor belt internal wire rope fittings, broken rope, broken wires, corrosion and other damage status accurate intuitive judgment, and automatic generation of test reports, having recorded and unattended automatically, I ensure the safe and efficient operation of the steel cord conveyor belt of Coal Preparation.
