He, unknown to the public, but always active in the first line of each optical fiber cable equipment installation and debugging; He, thin back, but always the first charge in the front, shoulder the plant equipment maintenance responsibility, to increase production and income protection. He is Xi Chunlei, manager of the engineering department of Nanjing Optical Communication Co., LTD.. Since his graduation in 2008, he had engaged in working at nearly 14 years with his continuous exploration and hard efforts. 
In 2012, the leadership team of Nanjing company made the bold decision of independent research and development of drawing tower after careful research and analysis and prospect forecast. In the face of a series of unknown problems, Comrade Xi Chunlei looked up information, looked for solutions, ran on site and checked parameters. In just one year, under the support of output line and company leaders, the project team he led was a great success. ‘s first generation of fully independent research and development wire drawing machine was formally put into operation, realizing the leap-forward from 0 to 1.
Later, from 2015 in the second generation of wire drawing machine design research and development, upgraded to 2019 of the 2017 old drawing tower of the third generation of wire drawing machine design research and development, every innovation promoted, he would go all out, with equipment research and development team members overcome difficult, no matter how difficult the project process, each time they can fulfill the task ahead of time, for the mass production for the early time, For Nanjing ’s market brand promotion and bigger and stronger laid a solid foundation.
During this period, when he led the construction project of Drawing Area 2 in 2019, in order to realize the goal of putting into production as soon as possible, he worked overtime continuously and fought hard on the project front line. In April 2019, his child was born. Facing the heavy responsibilities of family and work, he only accompanied his family for two days and immediately returned to the equipment installation site. Together with his team members, he completed the commissioning and production of 12 lines in only three months. 
The second hand of time points to the year 2020. With the continuous development of industry 4.0 and intelligent manufacturing 2025, equipment automation and intelligence have become the only way for enterprises to innovate and develop. At that time, Wu Haibo, general manager of , took the lead in proposing new goals and challenges for the long-term development of the company, requiring the equipment department to cooperate with the production department to meet the needs of The Times and make timely transformation and breakthrough. This time, Xi Chunlei took the lead again, called the team to actively explore new ideas for future fiber drawing manufacturing, and led the research and development of drawing big data acquisition platform. By collecting all the process parameters in the process of drawing, monitoring the fluctuation level, and giving an alarm immediately for exceeding the limit, so as to realize the unsupervised spot inspection in the production process, thus greatly improving the production efficiency. At the same time, the real-time storage of the collected production data greatly provides a reliable data source guarantee for the future traceability of data, the improvement of technology, the continuous improvement of the drawing level in Nanjing, and the stability of fiber production quality.
Excellence, the pursuit of the ultimate is each Beacon people inexhaustible power source. Then in 2021, in charge of the equipment department, deputy general manager of Yang Yang further overall planning, detailed decomposition, is proposed for nanjing wiredrawing intelligent manufacturing continuous improvement requirements of the project, for this reason, comrade XiChunLei revisited reel off raw silk from cocoons from light bar heating melt to coating and wire speed, tension control, diameter, until the line in the market of the whole production process, to further deepen the optimization, A lot of pioneering work has been done in the automation and intelligence of drawing process.
Among them, the traditional wire drawing production from low speed to high speed requires the operator to intervene in the whole process, through the manual constantly adjust a large number of parameters such as temperature, speed, pressure, to ensure the quality of the fiber in the production process, not only time-consuming and laborious and the control effect varies from person to person, so that wire drawing looks like a “handicraft work”. Can the system automatically rise to high speed without manual intervention when the optical fiber is wound to the reel at low speed? This is a difficult and profitable subject, Comrade Xi Chunlei face to the difficulties, brave to undertake the research of this subject. From basic model building to parameter matching, from algorithm design on computer to field verification on drawing site, he and his team have been rushing about in the production line for more than 100 days and nights.
The early tests didn’t go well, either because the fiber was broken or the quality wasn’t good enough, so the field operators looked at him and said, “Why is that guy testing again?” In the face of project development dilemma, Eric wu, the then director of fiber product line, the general manager gave us a great encouragement and train of thought guidance, “fiber drawing as’ and ‘a truth, the light bar heating furnace melting process and the water is in fact the process, rather than against the water rather than a bit by bit plus a seven eighty percent water, later gradually accurate water”. Wu general the theory of “and” direct control core, according to this train of thought, comrade XiChunLei will overthrow whole drawing control algorithm, design a new control logic of the bottom of society, at the same time, according to the big data acquisition platform provides basic data and find the optimal acc function, finally gained amazing drawing effect: around the fiber after automatic acc, don’t need human intervention; The speed increase time at 3000m is shortened from 2-3 hours to the fastest 30 minutes, and the efficiency is improved by at least 100%. The fluctuation of the fiber’s outer diameter was increased from 95% ±0.5μ to 99% ±0.3μ, and the stability was improved by at least 40%. The resulting reduction in labor cost, energy consumption and light rod consumption has generated annual revenue of more than one million yuan for Wasin Fujikura.
As one of the pilot projects of intelligent wire drawing production within the group, the big data platform of Wasin Fujikura from scratch has greatly promoted the improvement of intelligent wire drawing manufacturing level of Wasin Fujikura, improved the automatic manufacturing level of Wasin Fujikura, and pointed out the direction of unmanned factory research and development in the future.
“Persistent” focused, precise style, keep improving, dares to innovate, this is comrade XiChunLei interpretation of spirit, it is the dedication and enthusiasm, he grew from an ordinary internship employee wiredrawing equipment diagnosis expert for Wasin Fujikura, become the nanjing company leader of intelligent manufacturing.
To see the world in a grain of sand, life in a drop of water. For many years, Comrade Xi Chunlei has been working hard in the ordinary post, for their love and pursuit of optical communication cause silently dedication. It is this persistence and persistence that inspires more and more nanjing Huaxin Fujicang employees to gradually develop a working style in which everything is explained, everything is determined and everything is echoed. In the future, Comrade Xi Chunlei will keep the spirit of never slack off, continue to be a reliable beacon cable people, in the field of equipment training and lead more Wasin Fujikura staff to challenge the limit of non-stop, break through the future.
