Research on the image acquisition processor of monitoring system for longitudinal rip of conveyor belt

Abstract

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 collect multi-channel linear array cameras images, and then process and transmit them. The circuit of the image acquisition processor with the TMS320C6678 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 acquisition processor and the host computer. Experiments show that the image acquisition processor can acquire multi-channel conveyor 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 longitudinal rip monitoring system.
