Summary of Communication Engineering Professional Training (3 articles)1July 1 1 Harbin Engineering University on Monday morning.
We came to the School of Information and Communication Engineering of Harbin Engineering University as an intern. We visited the high-frequency electronics laboratory, the basic circuit laboratory, the electronic circuit 1 (analog circuit) laboratory and the digital circuit laboratory under the instruction of Harbin Institute of Technology.
Among them, the digital circuit laboratory impressed me the most. The indoor equipment is mainly the FPGA experimental box, and you can get a shared chip without making a film, with rich triggers and I/O ports.
After that, we visited Harbin e-sports base. In the training area, we learned that each computer here has two megabytes of memory, Samsung flat panel display, and the complete set of equipment is about 1000 yuan. Its training area includes two Gigabit switches and seven100m switches.
Tuesday morning, July 12, Sunshine Information Lecture Hall
Professor Zhang Xin from the School of Information and Communication Engineering of Harbin Engineering University gave us a report on the influence of electromagnetic field radiation on biology and matter in the information lecture hall.
The main contents of the report are:
(1) Influence of electromagnetic field radiation on human body
(2) Effects of electromagnetic field radiation on plants
(3) the influence of electromagnetic field radiation on animals
(4) the influence of electromagnetic field radiation on other substances
(5) Humans should keep our electromagnetic environment.
The professor's explanation made me understand the function of electromagnetic field and the seriousness of its harm, and realized that everything has two sides, that is, it brings us convenience and progress, but also brings harm to mankind. Among them, people around large bases (large transmission towers, substations, etc.). ) It is easier to get cancer than normal people. We also learned about the influence of electromagnetic field on living things and matter, and the influence of electromagnetic radiation on human body. We humans should make rational use of electromagnetic resources.
12 On the morning of Wednesday, July 30th, it turned sunny to heavy rain. Harbin meilong electric control co., ltd.
Meilong Electric Control Co., Ltd. is responsible for developing and producing all kinds of electric control components of shearer, and the products have been applied in coal mine systems all over the country. The company's 1400 high-power shearer is the largest shearer in China and even in Asia, with a daily coal mining capacity of 16200 tons.
Through the study in the design room, we know that the intrinsic safety board is used to protect the working power supply from exceeding 1 amp, because 1 amp will be automatically kept at 1 amp to prevent gas explosion. Another important component, frequency converter A800 series (Finland), adopts AC -DC- AC mode. Refrigeration equipment is water-cooled, which is determined by the environment, because if the air cooling performance is good, it will produce a lot of dust and other excreta, which is not allowed in the underground environment.
During this visit, we noticed that most of the equipment was imported from abroad because the imported products had excellent performance. We need to assemble these devices together, coordinate the parameters of each part, and even adjust various indicators to achieve certain functions. This also shows that we still rely on foreign support in technology, which also requires us to study hard and strengthen the research and development and accumulation of science and technology.
Feelings and experiences:
After the on-site visit, I better combined my theoretical knowledge with practical application. I have a deeper understanding of communication professional knowledge, realized the importance of theoretical study, and of course found the necessity of combining practical application.
Through cognitive practice, we have a perceptual knowledge of industrial design, production and scientific research, an updated understanding of communication products and system technology, assembly and debugging, especially the skilled use of experimental equipment, which puts forward stricter requirements for mastering certain experimental common sense.
I suggest that the school arrange more such internships to improve the utilization rate of the laboratory. It is best to let students design, operate and innovate by themselves, and let us combine more theory with practice, so as to cultivate our ability and improve our quality. Let us be more interested in what we have learned, so as to study and explore with higher enthusiasm.
Summary of practical training for communication engineering specialty (3) 2 University is a temple to absorb knowledge, and practice is the best entry point to combine knowledge with practice, and it is an experience that every student must have. It is to let students further understand the nature of this society. This is personal experience, which is knowledge that we can't learn in class, because only personal experience can be regarded as a thorough understanding. Understanding it has opened your eyes, increased our knowledge and laid a solid foundation for us to go to society in the future. Through many efforts, I am honored to be an intern in China Unicom. My main job is sales staff. The following is the appraisal of this internship.
In order to achieve the best internship purpose, I want to experience the experienced people in this society and constantly cheer myself up. The word "hard work" keeps circulating in my mind. During my work, I understand that it is very important to communicate with my colleagues, which is very important for my work, so that I can get along with my colleagues naturally and work quickly. I gradually gained the trust of my boss and began to do some relatively simple business for me.
However, time passed quickly. After staying there for a month, I entered another link-selling mobile phones, which was originally a very tedious job. In this internship, I was so bored and tired of facing boring computers and mobile phones all day that I made a lot of mistakes when paying, and the more mistakes I made, the more annoying I became. Of course, this will crush your self-confidence and make this job "worse", but as long as you really put your heart into it, it will be handy. Both sides have their own sources of information. Interest has come, and the more you do it, the more fun you feel, and the harder you do it. Liang Qichao said: "On the contrary, it is also interesting. As long as you are willing to work hard, people who go to the seat will happen. So, remember to pay: carelessness, carelessness and impatience will not succeed. Do everything the same. What is needed is perseverance, carefulness and perseverance, both of which are indispensable, so that you can reach the other side of success and not fall into the water halfway. It's like a lonely trip. As long as you persist, you will succeed. Sweat is the road to success.
Social practice brings us confusion as well as joy and fun. In social practice, I feel my poverty, my smallness and insignificance. I feel the strong cohesion of the whole society. On the other hand, we have exercised our abilities, grown up in practical activities, learned from practical activities and benefited from practice. Enriched life and self. Communicate with others to enhance oral expression ability. At the same time, it also made me understand a truth: "that is, customers are the first. Serving customers wholeheartedly, helping others in Yiwu, and letting others see their achievements, is to revel in the fun of work. Although sometimes I am very tired, I feel that I am constantly growing and growing meaningfully. After that, I obviously found myself cheerful. Although I can't change some things by myself, if I have the strength of more people and the cooperation of Qi Xin of the whole society, this is the foundation and source of strength. On the other hand, I am aware of my own shortcomings. I don't have the experience and eloquence to communicate with others, which won't work in this society. Dare to challenge is the basic quality of a college student. So I took the question mark in my heart and embarked on the road of social practice, ending this internship stage. In this internship of China Unicom, I benefited a lot. After only two months of internship, I will benefit for life.
Although the internship time is very short and the contact work is very simple, I still learned a lot of knowledge and experience, the communication between people in this society, the professional ethics of this society and the integrity of the society. Are all indispensable. Through practice, I can better understand my own shortcomings, the inseparable relationship between China Unicom and our lives, the nature of China Unicom's work and all aspects of this society, which will enable me to better plan my career, set my own life goals, and move towards the future and success.
Summary of Communication Engineering Professional Training (3) 3 Practice Purpose:
In order to consolidate the main business knowledge of communication engineering specialty, improve the understanding of actual production skills, deepen the concreteness of communication-related products and production processes, and learn more communication knowledge outside textbooks, which will be better helpful for the study of this professional course in the future.
Foreword:
Through nearly a week's study, we have learned a lot from sensibility, which has a far-reaching impact on our future study and research direction. Through this internship, I enriched my theoretical knowledge, enhanced my observation ability, broadened my horizons, and gave me a qualitative understanding of my future work, which really made me gain a lot. Now I will summarize this internship from three aspects: the content of the internship, the harvest of the internship, the direction of my own efforts in the future, and my feelings.
Preparatory work:
September 1, attended the cognitive practice mobilization meeting. At the meeting, the teacher who led the team explained to us in detail the matters needing attention during the internship and the unified arrangement of the internship these days, and encouraged everyone to ask questions to the technicians frequently during the internship. I hope I can have a better and deeper understanding of this major through this internship.
