He said that in 2022, the operation pressure of the chemical fiber industry is still great. In the face of the uncertain market situation, he called on enterprises to pay attention to both risk prevention and internal training, and move forward to the high-quality development of high-end, intelligent and green.

　　 Wang Yong, director and general manager of beizisuo (Beijing) science and Technology Development Co., Ltd From the background and requirements, technical solutions, technical innovation points, technical achievements, application scenarios and other aspects, this paper elaborates the complex equipment digital twin system. According to reports, the twin system and equipment independently developed by Beizi science and Technology Co., Ltd. has advanced technologies such as WYSIWYG 3D visual monitoring, key equipment virtual training, fault diagnosis and prediction and early warning, adaptive scheduling optimization of operation strategy, AR remote operation and maintenance cooperation, and virtual model construction, Typical scenarios such as unwinding robot and digital twin control system in fiber production workshop have been effectively applied.

Through the enabling of digital twin technology, the intelligent and information level of production line and equipment can be effectively improved. The mean time between failures of equipment has also been greatly improved. The equipment fault processing time has been reduced by 30%, and the cost of manual operation and maintenance has been reduced by 20%.

Li Jie, School of mechanical engineering of Donghua University and Engineering Research Center of Ministry of education of textile equipment, interpreted the implementation guide of maturity evaluation of textile intelligent manufacturing. She said that intelligent manufacturing is a system engineering with rich connotation, involving the integration and integration of multi domain technologies. At the same time, only through the standards can we achieve the specific requirements of consistency, reliability, security, interconnection and other specific requirements.

She pointed out that the intelligent manufacturing capability maturity model can be divided into one level to five levels, realizing process management, digital transformation, network integration, intelligent production and industrial chain innovation. In order to better evaluate the maturity of Intelligent Manufacturing in textile enterprises and promote the further application of Intelligent Manufacturing in subdivided industries, the implementation and Application guide of Intelligent Manufacturing in textile industry will be issued in the form of operation instructions. The implementation of the application guide requires different levels in different scenarios. Therefore, a table is formed according to the grading comparison of maturity to help enterprises evaluate and put forward guiding suggestions. At present, under the organization of China Textile Machinery Association, industry associations and relevant units are working out the implementation guide for intelligent manufacturing application in chemical fiber industry. She called on more enterprises to participate in the process, so as to provide reference for enterprises to continuously improve the core competence of intelligent manufacturing and evaluate the level of intelligent manufacturing.
