摘要
针对带式输送机纵向撕裂检测便携式高精度需求,设计了一种基于边缘计算的便携式高精度输送带纵向撕裂检测系统。系统包括输送带纵向撕裂图像数据采集终端和中央控制平台2个部分,采集终端为FPGA及外接器件,终端和中央控制平台经由5G网络实现数据云端通信。文中阐述了系统框架和视觉检测方法,并详细展示了硬件选择与检测结果。利用文中改进的算法,降低了数据计算与传输负载,提高了检测效率。实验结果表明:系统对采样点的检测误差率小于2.8%,满足高精度的检测需求。
Aiming at the portable high-precision requirements for longitudinal tearing detection of belt conveyors,a portable high-precision longitudinal tearing detection system for conveyor belts based on edge computing was designed.The system included two parts,a conveyor belt longitudinal tearing image data acquisition terminal and a central control platform.The acquisition terminal was FPGA and external devices,and the terminal and the workstation realized data cloud communication through the 5G network.The article expounded the system framework and visual inspection method,and showed the hardware selection and inspection results in detail.Using the improved algorithm,the load of data calculation and transmission was reduced,and the detection efficiency was improved.The experimental results show that the detection error rate of the system for sampling points is less than 2.8%,which meets the high-precision detection requirements.
