    • Research on surface micro-defect detection method and application
    • CHEN Hu, WANG Cheng, LU Renqian
    • Information and Communications Technology and Policy. 2021, 47(1): 20-26. DOI:10.12267/j.issn.2096-5931.2021.01.005
    • Abstract ( 480 )   
    • Surface micro-defect detection has a pivotal position in the industrial field. At present, a large number of manual or traditional machine vision methods are still used for surface micro-defect inspection, which leads to unstable defect detection accuracy on the sub-micron level, which are difficult to be fully promoted in the industrial field. The surface micro-defect detection method based on multi-technology fusion combines the latest object imaging technologies, cloud computing, AI and 5G and other cutting-edge technologies to establish a micro defect detection system to accurately detect defects in the micro field with fast recognition speed and high accuracy, low cost, strong traceability, data analysis, intelligent counter-control, etc., which overcomes the shortcomings of traditional detection methods, such as single-point detection, low accuracy, high cost, lagging response, poor analysis, and weak system.Finally, the application of this technology in typical industrial scenarios is discussed.

    • Construction of data transfer mechanism from shipbuilding to operation
    • ZHANG Shuo, DENG Yibin , FAN Shidong, GAO Yongan, CHEN Ming
    • Information and Communications Technology and Policy. 2021, 47(1): 27-33. DOI:10.12267/j.issn.2096-5931.2021.01.006
    • Abstract ( 360 )   
    • At present, the data from ship manufacturing to operation is mainly transmitted by description documents. A large number of documents make the initialization of ship maintenance management system cumbersome and difficult.In order to solve this problem, firstly, the data demand of ship maintenance is analysed, and the data generated in the upstream manufacturing process is sorted out. A data transmission mechanism based on the data demand of ship maintenance management system is constructed by using handle identification analysis system. Then, the data transmission from ship manufacturing to operation process is illustrated by taking the domestic sewage treatment plant of Changshi 10 as an example. The data transfer mechanism based on identification analysis system can effectively improve the efficiency of data transfer from ship manufacturing to operation, reduce the difficulty of initialization of maintenance management system, and improve the level of ship maintenance management.
