摘要
提出了一种多视点输送带纵向撕裂故障在线监测系统的设计方案,实现了输送带纵向撕裂的检测,提高了输送带的检测宽度,降低了线阵CCD相机与线阵LED光源方位调整的难度;提出了一种图像采集处理器的设计方案,实现了对多路线阵相机图像的采集、处理及传输。以TMS320C6678为核心设计了图像采集处理器的硬件电路。在集成开发环境CCS上,基于SYS/BIOS系统设计了图像采集处理器的软件,实现了对多路线阵相机的控制、多核调度及与上位机的通信。实验表明,该图像采集处理器实现了多路输送带图像的采集、处理和高速传输,最多可连接4路线阵相机,每路相机采集速率可达25 Mb/s,可用于多视点输送带纵向撕裂故障在线监测系统。
A design of multi-view on-line monitoring system for longitudinal rip of conveyor belt is presented, which can be used to detect longitudinal rip of conveyor belt. This system improves the detection width of conveyor belt, and reduces the adjustment difficulty of orientation between linear array CCD cameras and linear array LED. An image acquisition processor is designed to col-lect multi-channel linear array cameras images, and then process and transmit them. The circuit of the image acquisition processor with the TMS320 C6678 as the core and the software on integrated development platform CCS based on SYS/BIOS are designed.The software realizes controlling multiple linear CCD cameras, multicore scheduling, and the communication between the image ac-quisition processor and the host computer. Experiments show that the image acquisition processor can acquire multi-channel convey-or belt images, with processing and transmitting high-speed. The image acquisition processor can connect four linear array CCD camera at most, with each linear CCD camera acquisition rate of 25 Mb/s, which can be used on the multi-view conveyor belt lon-gitudinal rip monitoring system.
