Hello, I'm Li Ning

Today, Xiao Bian came to a spacious, bright, clean and warm office area to conduct interviews in this issue of "People Interview". This is the Institute of Composite Manufacturing and Intelligent Identification. The guest of our interview in this issue is Li Ning, head of the machine vision department of the Institute. Please follow the steps of Xiao Bian and learn about Li Ning's story.

Li Ninghao, who had contact with Li Gong during the last news interview of the Institute, specially debugged the testing equipment to cooperate with the publicity. He thanked him for his full support for the work of the Institute and was very happy to accept our interview this time. I don't know you very well, including me. Let's introduce ourselves first?

Hello everyone, my name is Li Ning, Hebei Baoding people, born in 90, graduated from Hebei Normal University of Science and Technology, master's degree.

In June 2016, I worked as a machine vision engineer in Tianjin Construction Machinery Research Institute as an intern. From July 2017 to June 2020, he worked in Tianjin Construction Machinery Research Institute Co., Ltd., and successively worked as a machine vision engineer and project manager, mainly responsible for the operation and implementation of vision-related projects. In June 2020, he came to the Institute of Composite Manufacturing and Intelligent Identification of Tianjin High-end Equipment Research Institute of Tsinghua University, and is currently the head of the machine vision department.

You haven't been in the courtyard for too long, but there is always a feeling that you have known each other for a long time. The composite manufacturing institute was established in 2018 and moved into a new area and renovated at the end of 2020. It seems that you moved into a new working environment soon after you joined the job. Now the office environment is so good. Can you show us around and how are you feeling working here?

Well, I can give you a tour.

As you can see, our office environment is relatively warm and the working atmosphere here is very harmonious, so everyone is relatively comfortable and practical in doing things.

Yes, every time I come here, I can feel that the atmosphere is very harmonious. We are the Institute of Composite Manufacturing and Intelligent Identification. Can you tell us about the overall research and development direction and achievement transformation of the Institute?

Our institute mainly combines intelligent optical inspection, on-line inspection of inner hole spraying and intelligent identification technology to develop high-reliability manufacturing equipment for various complex process products. The research and development direction is mainly divided into four parts, including intelligent equipment research and development, machine vision equipment customization, surface spraying, carbon fiber products.

At present, good transformation results have been achieved. The aircraft tire forming machine developed by us is used for the processing and production of aircraft tires. The carbon equipment developed is used for the processing of graphite electrodes and carbon electrodes. Graphite electrodes are widely used in blast furnace steelmaking and aluminum making. There is also an internal thread detection technology based on machine vision. For the first time, we have adopted machine vision technology to solve the problems of internal thread size and defect detection, from the traditional contact detection to non-contact detection, reduce the labor intensity, but also for the enterprise to improve the efficiency; there is the automobile steel seal identification detection, the use of machine vision technology to solve the problem of automatic identification of automobile steel seal.

At present, our institute has also set up its own industrialization company, Qingyan Han High-tech (Beijing) Co., Ltd.

What is related to you, can you give us a detailed introduction of this part of the situation?

I am mainly responsible for the intelligent recognition part. Intelligent recognition is mainly divided into 2D recognition and 3D recognition. The recognition means mainly include traditional recognition technology and deep learning technology.

Some of the parts I am responsible for are not very convenient to introduce. Part of the business is automatic identification technology for automobile steel printing numbers. Now a handheld device is developed, which mainly solves the problem of character recognition in the automobile industry. Now in the process of automobile processing, each car base has unique 0-9 and A- Z random steel printing characters, which are used for automobile production traceability. In the past, most of the character equipment was fixed, with low flexibility and poor versatility. Now the handheld terminal equipment developed by us has the characteristics of simple operation, flexibility and easy maintenance.

Can the application scenario of machine vision technology give us an image description, and which industrial fields are now used?

At present, machine vision technology has many applications in the industrial field, mainly in the automotive, rubber, textile, machinery and other industries. For example, the problem of thread breakage detection of textile machines in the textile industry, after the original equipment is broken, manual regular inspection will often lead to thread breakage and invisible situation. The use of machine vision technology to detect thread breakage can be detected in real time, thus ensuring the weaving effect of cloth and reducing the labor intensity of personnel.

After listening to your introduction, I have a deeper understanding. A "point" R & D technology has actually been widely used in industry.

Having talked about your work situation, let's talk about the topic of life. Are there any people or things that impress you in your work and life?

One thing that impresses me now is that I have been stationed in the enterprise site for 8 months to solve the problems on the project for them. It took a long time, and finally the problem was solved satisfactorily. Personally, I am quite satisfied. This matter impressed me deeply.

Solving problems for enterprises gives us a full sense of accomplishment.

I can feel that our team is a very cohesive and energetic team. Can you talk about the goals of our institute?

It is more appropriate for our Professor Liu Dameng to answer this question. As far as I know, the goal of the institute is to be guided by market demand, promote the market with research and development, guide research and development with the market, and combine research and development with the market. Solve the important and difficult problems of the market and solve the "stuck neck" problem of the industry.

Indeed, solving the national and industry "stuck neck" problem is a sentence often mentioned by our team leader, and many research institutes regard it as their own responsibility.

Can you reveal your current personal situation? Has such a good boy already started his own family?

Yes, I have set up my own family. I have been married for more than a year. I have a lovely daughter. The child is almost one year old.

Where is your lover from?

Hebei Cangzhou people

Have you bought a house in Tianjin?

I have already bought it, it is in Dongli Lake.

Is it Peking University resources real estate?

No, it's Vanke's. You asked quite carefully.

When small make up will have this kind of gossip spirit, ha ha. Your hometown Baoding is not too far away from Tianjin. How often do you go home at ordinary times? Are there any brothers and sisters in your family?

I should go home 2-4 times a month. I have a sister and am married.

It is quite practical to have brothers and sisters at home to take care of your parents, and you can also struggle at ease in other places. Are there any special events or people in your life that have particularly influenced you?

In my career, my wife's encouragement and support to me is the driving force for my continuous progress. In addition, my graduate tutor, honorary teacher and Dr. Xu Jiayin, had a great influence on me. My tutor led me into this industry and provided me with rich teaching resources, which gave me the opportunity to contact and learn from this industry. Dr. Xu has been taking care of me in the company since I was engaged in this industry. He has not only taught me how to deal with people, but also provided a lot of project resources. I would like to take this opportunity to express my heartfelt thanks to my wife, Dr. Rong and Dr. Xu.

Do you have any hobbies, traveling, reading, playing online games or sports?

I usually like reading books, and sports are okay. Billiards, table tennis, basketball, and chess are all involved, but I don't have much time to play now.

OK, after talking so much, I finally want to know what personal goals you have set for yourself?

In my career, I will continue to improve my business and technical capabilities, strive to reach a higher level in my career, manage my family well, and make life better and better.

Okay, thank you very much Li Gong. I believe this goal is also the goal of many people, work and life to a higher level. Thank you for taking your precious time, accepting our interview and leading us to visit the research institute. Next, please answer our Brewster questionnaire.
