Youth story in creative activity room ■ Hou Rong, Fu Kang, special reporter of PLA Daily, Xiongfeng Graduation photos of naval engineering university students. Provided by the author In midsummer, the campus is filled with the smell of graduation and parting. "Face recognition successful, welcome." Zheng Hengquan, a senior majoring in electronic countermeasures at the school of electronic engineering, Naval University of engineering, entered the creative activity room through his own face recognition lock designed and installed, and invested in the technical breakthrough of "disinfection UAV". He wants to finish this work before graduation and make more contributions to the epidemic prevention work of the college. Sit down, Zheng Hengquan's eyes focused on the innovation wall in front of him. The first prize of the world robot competition, the special prize of the military college students' military modeling competition... Photos flashed like movies, bringing his thoughts back to the good time of innovation and hard work with his comrades in arms. In recent years, the student team 4 of Zheng Hengquan encouraged students to study and innovate in combination with their majors, and opened the power "valve" of students' bold imagination and innovation with a "creative activity room". Among the 54 students in 2018, 40 won national competition awards. In April this year, a competition achievement of Zheng Hengquan was also used by a teaching and Research Office of the University as one of the supporting materials for applying for the military science and technology progress award. At this moment, the ups and downs, laughter and feelings along the way with his comrades in arms are surging in Zheng Hengquan's heart. The Innovation story of this group of young comrades in arms starts from this creative activity room. "The process of innovation is the process of constant trial and error correction" Zheng Hengquan never thought that the university would have 10 provincial and ministerial level and above competition award certificates in four years. If someone applied a space-time magic to make Zheng Hengquan face-to-face with himself four years ago, it would be difficult for the "two" to agree on these achievements. "Divergent thoughts fly like youth, and enthusiasm for action dissipates like morning mist." This is a teacher's evaluation of Zheng Hengquan when he graduated from high school. According to wuyanbin, the current instructor, Zheng Hengquan is a down-to-earth guy with creativity, ideas and actions. When did the changed chemical reaction happen? Captain zhaohaitao told a story about the door card. Shortly after entering school, Zhao Haitao seriously criticized the material manager of the student team for delaying the pull drill because he could not find the warehouse door card. At the end of the drill, several students began to think about more efficient management methods with a stack of door cards. "Why do you have to use a door card? Adding a face recognition lock can solve the problem." Zheng Hengquan happened to pass by and said casually. At that time, Zheng Hengquan was already a little famous "programming master", and his brain turned very fast. Although there are often "creative" jumping out, he often can only maintain the heat for 3 days. "Is it possible to light a fire in his heart?" Zhao Haitao assigned a task to Zheng Hengquan half excitedly and half forcibly - to make a face recognition lock for the warehouse. Zheng Hengquan answered the "challenge" with great enthusiasm. He was as enthusiastic as ever, and also excitedly mobilized other students to participate. However, the first "product" test poured cold water on him - face recognition flashed slightly twice, but the door lock switch did not move. "Too much trouble, don't do it!" Zheng Hengquan quit with both hands. After checking the night for several days in succession, Zhao Haitao saw a little difference in Zheng Hengquan's tossing and turning. "The problem that can be solved by buying a personal face recognition lock in the market is that it takes so much time and materials to build it, and it's a little more than worth the loss to try it again!" Facing Zheng Hengquan, who confided his heart, Zhao Haitao also opened his heart: "the process of innovation is the process of constantly trying and correcting errors. You change your mind and try several times, and I'll find you a room." In the buzzing activity room, Zheng Hengquan was half kneeling beside the equipment, measuring with a pencil and recording the voltage and frequency readings... During that time, everyone passing by had to look around. The room borrowed by the team leader became the most "eye-catching" secret corner of the student team. A month later, Zheng Hengquan successfully made a face recognition lock with several classmates and expanded its application to all rooms of the student team. His wilting learning attitude has also taken on a new look. Zheng Hengquan's situation is not uncommon. The post-2000 students have a broad vision, active thinking, and have their own unique views on problems. They are eager for success and afraid of failure. They have many ideas, but it is difficult to take the first step. They are guided to connect their interests and specialties with the needs of future positions. The role of preaching alone is limited. Zhao Haitao keenly captured the breaking point from Zheng Hengquan's innovation case. They applied to the brigade to solidify the temporarily borrowed room into the creative activity room of the student team, encouraged more students to express their ideas, and encouraged them to find ways to solve problems through trial and error. As time goes by, there are many new faces in the creative activity room. Student Li Tingan thought about using data crawlers to sort out and summarize the results of the student team from the educational administration system; Student tanghongsheng wants to compile a software and use the physical fitness data to calculate a special training plan suitable for him... In a small activity room, there are more and more creative stickers on the brainstorming board, more and more busy figures of students' hands-on practice, and more and more aggressive and hardworking people who dare to try and dare to break through without giving up. If you don't know how to "use" failure, you will never know how to innovate Approaching graduation, Wu Yanbin combed a "creative list" and listed the new ideas and good ideas of the students on the brainstorming board in chronological order in recent years. At the beginning of school, most of them are wild and unrestrained imagination. With the increasing number of group discussions and joint verification, more ideas of using professional knowledge to solve practical problems have been put forward, and the operability and feasibility are becoming stronger and stronger. It is in this repeated practice that everyone's confidence and toughness to tackle key problems have been greatly improved. "I like mathematical modeling because it can be used to solve many problems around me." Student Li Xu tasted the sweetness. Originally a little introverted, he summoned up the courage to post his interests and ideas on the brainstorming board. He tried to analyze various small problems in life time and again with the method of modeling, and became more and more handy in the application of mathematical modeling. At a class meeting with the theme of "seeking combat effectiveness from scientific and technological innovation", Wu Yanbin invited several professional teachers to communicate with the team. The teachers and students talked about their experience of participating in modeling competitions and the frontier trends in professional fields. Li Xu was fascinated. He stood up and said, "I want to participate, too!" The fifth military college students' military modeling competition kicked off. After choosing the scheme, Li Xu and his teammates wrote more than 6000 words of research and judgment scheme and more than 200 lines of calculus code. Unexpectedly, the result of process checking is one dead end after another. "What should we do? If the workload of the adjustment plan has to be at least 10 times, is there time for two and a half days?" Li Xu and his teammates are worried. "If you have ideas, you dare not count them. Wasting ideas is' lazy '!" Thinking of the days and nights of fighting in the creative activity room, Li Xu and his teammates began to act separately, adjust the framework scheme, determine the boundary conditions, write code, draw pictures, plan and integrate them into writing For two days and three nights, the activity room was lit up, and they finally submitted their results half an hour before the deadline. 3600 lines of code and detailed data support the conclusion, which made the judges refreshing. In the end, they won the grand prize in the competition. When the news came back to the team, Wu Yanbin had a smile on his face for several days. At that time, he set up a wall of innovative achievements in the activity room, claiming to be the innovative "celebrity list" of the student team. Seeing more and more achievements and names on the wall of innovative achievements, the "ripples" in the creative activity room are also expanding. In his spare time, wuyanbin actively contacted with the teaching and research departments and went to the innovation laboratories of the school with his classmates for on-site teaching. Looking at the "sophisticated" innovation achievements in front of us, listening to the innovation stories of teachers and seniors, we learned while understanding, and more understood the profound connotation of the concept of "innovation without taboo and innovation in order" put forward by the University. "You don't have to shrink back because of failure. If you don't know how to 'use' failure well, you will never know how to innovate." When hearing the story of several major changes before the finalization of a scientific research achievement that won the first prize of the military scientific and technological progress award, Tang Hongsheng thought: "I have encountered obstacles in my previous attempts to write physical training software, and I just want to give up. Maybe these failures hide the key to success, so I have to look for it when I go back..." Guided by the example of "wall + side", the innovation wave of this student team is surging. For a time, there was an endless stream of students in the creative activity room. Graduation is not only the end but also the starting point, running to the vast sea with the maker's dream In the creative activity room, a special handover ceremony is under way. 2018 students who are about to bid farewell to the campus have handed over their unfinished creative works such as jamming robots and new energy submarines to their younger students. "In the hands of senior student Zhao Yifan, it is a remotely operated unmanned submersible. After being handed over to us, it 'evolved' into an automatic tracking unmanned submersible." At the end of the ceremony, Zheng Hengquan grabbed his younger brother Chen Weiming, pointed to a snow-white model aircraft and said, "in the future, will it fly? Can it drive to the shore? It depends on whether you can insert 'wings of imagination' into it!" That year, Zheng Hengquan and his partners in the creative activity room participated in the international underwater robot competition, and won the third prize with this small white boat equipped with automatic tracking function. "The boat left by the seniors before graduation is the starting point for us to harvest innovative achievements, and I hope you can find a breakthrough in your own innovation." Zheng Hengquan said to the younger students. On the campus in July, many creative graduation project defense were carried out one after another, and the students went to the podium one after another to write their papers on the sea battlefield in the future. For Li Tingan, a student majoring in military big data, the design made at graduation is not only the summary of four years of study, but also the "first step" to integrate the flavor of war into innovation. When Li Tingan was on probation in the grass-roots army, he coincided with the actual military exercise of the army. He noticed that the details of the equipment displayed in the electronic situation map used by the army were old. He consulted the technical backbones on the ship many times and clarified the problems that restricted the updating of the equipment map. After staying in the creative activity room for a long time, Li Tingan wants to try everything himself. After returning to school to carry out his graduation project, he chose this project for approval. With the help of his tutor, he continued to break through difficulties and improved the floating information bar of the situation map for the main combat equipment with professional knowledge, making it closer to the actual combat requirements. Li Tingan's graduation project puts forward some forward-looking improvement measures against the current practical training. The teaching and Research Office of computer and data engineering of the University cited its achievements as one of the important materials for applying for the 14th five year plan project. The night before the defense, a night rain quietly visited the campus. After the heavy rain, the green branches and buds stretched quietly. Magnolia on both sides of the road emitted a refreshing fragrance, and the campus was full of vitality. "Generations of scientific and technological pioneers of the navy have rushed from you to the thousands of miles of sea..." with the high school song, Li Tingan greedily sucked the fragrance of the campus and made a career plan for himself: bring the four-year learning and innovative thinking to the grass-roots forces, and pursue the dream of makers in a broader world
