The summary is a time period of achievements, problems and experience and lessons learned in a comprehensive and systematic summary of the written material, which helps us to find the work and the development of things, so that we can master and use these laws, I think we need to write a summary of it. How to write a summary will not be the same? The following is my collection of communications engineering professional practical training summary (3), for reference only, we take a look at it.
Summary of practical training in communications engineering (3) 1July 11, the morning of Monday clear Harbin Engineering University
We came to the Harbin Engineering University of Information and Communications Engineering College visit internship, we were in the Harbin Engineering laboratory teacher's explanation of the visit to the high-frequency electronics laboratory, circuit basis laboratory, electronic circuit 1 (analog circuit) laboratory, digital circuit laboratory
Among them, we visited the high-frequency electronics laboratory, circuit basis laboratory, electronic circuit 1 (analog circuit) laboratory, digital circuit laboratory.
One of the digital circuits laboratory gave me the deepest impression, indoor equipment is more advanced mainly FPGA experimental box, the device does not need to cast the chip production can be used to get the chip, there is a wealth of triggers and I/O ports.
After that we visited the Harbin eSports base, in the training area we learned that each computer here is two megabytes of memory, Samsung flat screen monitors, the whole set of equipment about 10,000 yuan. Its training area*** has two Gigabit switches and seven Hundred Gigabit switches.
Tuesday, July 12 morning clear Information Lecture Hall
Professor Zhang Xin, School of Information and Communication Engineering, Harbin Engineering University, gave us a "report on the effects of electromagnetic field radiation on living beings and matter" in the Information Lecture Hall.
The main contents of the report are:
(1) The effect of electromagnetic field radiation on human body
(2) The effect of electromagnetic field radiation on plants
(3) The effect of electromagnetic field radiation on animals
(4) The effect of electromagnetic field radiation on other substances

July 12 morning Wednesday sunny to rainy Harbin Meilong electric control limited liability company
Meilong electric control limited liability company is responsible for the development and production of a variety of models of coal mining machine electric control part of the product is applied by the national coal mine system. The company's 1400 high-power coal mining machine is currently China and Asia's most powerful coal mining machine, mining up to 16,200 tons of coal per day.
Through the study in the design room, we learned that the intrinsically safe board is used to protect the working power supply from exceeding 1A, because 1A will be automatically kept at 1A to prevent gas explosion. There is also an important part of the frequency converter A800 series (Finland), the frequency converter is used in the way of AC-DC. Refrigeration equipment is water-cooled, which is determined by the environment, because if the air-cooled performance is good but will produce a lot of dust and other excreta, which is not allowed by the mining environment.
The visit we note that most of the equipment is imported from abroad, that is because the imported products have excellent performance, we need to assemble these devices together to coordinate the parameters of the various parts, even adjust the various indicators to make it reach a certain function. This also shows that we are still technically dependent on foreign support, there is a certain degree of dependence, which also requires us to study hard to strengthen the scientific and technological research and development and accumulation.
Thoughts and insights:
After the site visit, I was better able to combine the theoretical knowledge I learned with practical applications. A deeper understanding of the professional knowledge of communications, recognizing the importance of theoretical learning, but of course, also found to be combined with the need for practical application.
Through the cognitive internship, I have a perceptual understanding of industrial design, production and scientific research, communication products and systems process, assembly and debugging have a newer understanding, especially on the skilled use of experimental equipment, to master a certain degree of experimental knowledge put forward more stringent requirements.
I suggest that the school should arrange more such internships, improve the utilization of the laboratory, it is best to allow students to design to operate to innovate, so that we have more theory to practice, so that more able to cultivate our ability to improve our quality. So that we are more interested in their own knowledge, so that we are more enthusiastic to learn to explore.
Summary of practical training in communications engineering (3) 2University is the temple of absorbing knowledge, and the internship is the combination of knowledge and practice of the best starting point for each student must have a period of experience, is to allow students to further understand the nature of the society, which is a personal experience, in the classroom is the knowledge we can't learn, because only a personal experience is considered a thorough understanding of it, to understand it to open your horizons and grow your knowledge. Understanding it opens up your vision and grows insights for us to step into society later to lay a solid foundation. Through the efforts of many, I am honored to China Unicom work internship, the main work is the salesman, the following is the internship identification.
In order to best achieve the purpose of the internship, I want to experience this society has experienced people, and constantly give themselves a boost, try to work hard this word constantly in their minds around, during the work period, I understand and colleagues to communicate with each other, communicate with each other, which is very important to the work, so that the natural smooth and colleagues to get along with the work, put in very quickly. Slowly got the boss's trust, began to give me to do some relatively simple business.
But time flies very fast, I was there for a month and then entered another link ---- to promote cell phones, it was very tedious work, during this internship I had felt all day long to face that boring computer and Cell phones and boredom, boredom, so that the payment of the bill to pay a lot of mistakes, the more wrong, the more annoyed, the more annoyed, the more wrong. Of course, this will break down the individual's self-confidence leading to the work of the "worse" but as long as you really put your heart and soul into it, but will be able to do it. The left and the right are very popular. Interest comes, the more you do, the more fun you feel, the more you do, the more energized. Liang Qichao said: "The opposite is also have fun, as long as you are willing to do it, go bit people will happen. Therefore, pay your dues and remember: carelessness, sloppiness, impatience, is not going to succeed, to do anything is the same, the need is to have perseverance, attentiveness and perseverance, the lack of one, that will arrive at the other side of the shore of success will not be halfway to the water. This is like a lonely journey, as long as you insist on going on, you will be successful, sweat is to help the success of the road paved.
Social practice activities bring us confusion, delight, fun. In the social practice activities, I felt my own meager, my own small and insignificant. Experience the strong cohesion of the whole society. The other side is that we exercise our ability to grow up in practical activities, learn in practical activities, and benefit from practice. Enriched life and self-enrichment. Communicate with people and enhance the ability of verbal expression. At the same time also let me understand a truth: "that is, the customer first wholeheartedly for the customer service, go to Yiwu to help others, so that others can see their own results, is their own intoxicated in the fun of the work. Although sometimes very tired, but more in the feeling of their own continuous growth, meaningful growth, after this I obviously found myself to become cheerful, although I can not change some things in a person's strength, but if some more people 's power, the whole community *** with the same efforts, which is the root of the power, the source of the power; on the other hand, I recognize my own shortcomings, inexperience, no The eloquence of communication with people, in this society is not feasible, for a college student dare to challenge is a basic quality. So with the question mark in my heart, I set foot on the road of social practice and ended this internship stage, in this China Unicom internship, I can be said to have benefited a lot. Only two months of internship, I am benefited for life.
This internship is very short, contact with the work is very simple, but still let me learn a lot of knowledge and experience, communication between people in this society, and this society's professional ethics, and social integrity. Are indispensable, through the practice I can better understand their own shortcomings, understand China Unicom and our lives are inseparable, as well as the nature of China Unicom's work, to understand all aspects of the community, to enable me to better do their own career planning, set a good life goal, to the future forward, to success.
Summary of communications engineering training (3) 3Purpose of the internship:
In order to consolidate the main knowledge of the communications engineering profession, to improve the understanding of the actual operation of the production skills, to deepen the communications-related products and production processes specific, to understand more about the communications aspects of the textbook outside of the knowledge of the future of the study of this professional course has a better help. The students will also be able to learn more about the communication process, which will help them to learn more about their specialty.
Preface:
Through nearly a week of study, we learned a lot of things from the perceptual, but also on our future learning and research direction to determine a far-reaching impact. Through this visit to the internship has enriched my theoretical knowledge, enhance my ability to observe, broaden the horizons, and make me have a qualitative understanding of the future work, really let me gain a lot. Now the internship on the content of the visit, the internship harvest, and the future direction of their efforts and the feelings of the three aspects of the summary.
Preparation:
September 1 this day we participated in the awareness of the internship mobilization meeting, where the teacher gave us a detailed explanation of the internship notes and other matters and the unified arrangements for the internship in the next few days, and encourage us to be diligent in the internship to the technicians to ask questions, I hope that through the internship, so we have a better and deeper understanding of the profession. The company's main goal is to provide a better and deeper understanding of the profession.
