[Abstract]:With the development of manufacturing industry, China's paper industry is developing towards automation and high speed. The paper quality testing method based on manual is of high cost, low efficiency, easy to miss inspection, and can not meet the increasing production demand. The adoption of automatic testing equipment has become an inevitable trend of the development of the industry. However, due to the limitation of actual production and technical strength, the development of paper quality inspection system in domestic paper industry is slow. Therefore, the research and development of paper quality inspection system has important engineering practical value for improving the automation level of China's paper industry. Aiming at the deficiency of the traditional paper quality detection method, the paper develops the paper field monitoring system software based on video analysis, and realizes the paper breaking detection by using the paper breaking detection equipment and the video acquisition equipment. The image collected in the process of paper breakage detection is analyzed to realize paper disease detection. The paper-making field monitoring system consists of video acquisition equipment, paper quality testing equipment, client and server. The server is connected to the paper breaking detection equipment, the speed equipment and the video acquisition equipment. The paper breakage detection device is used to detect and trigger the broken paper fault, and the speed of the paper tape transmission is obtained by the speed equipment. The time series of broken paper fault in the field of vision of each associated camera are calculated, and then alarm events are generated and the video of the linkage fault is viewed back, so as to realize the detection and fast location of the broken paper fault. Furthermore, this paper designs a paper disease detection algorithm based on image processing. The server realizes the detection of black spots, holes and edge cracks by analyzing the video images. The software of the paper making field monitoring system developed in this paper has been tested to realize the accurate detection and location of the broken paper fault. At the same time, the paper disease detection algorithm can realize the correct detection of the three kinds of paper diseases. The system provides a strong guarantee for the quality of paper.
