We will graduate in 2020. Under the arrangement of the school leaders, we will go out to practice in an electrical automation factory. First of all, let's learn what electrical automation is. The major of electrical automation technology mainly grasps the basic principles and analysis methods of electrical technology, power automation technology, all kinds of electrical equipment and automation equipment, and is a senior technical application-oriented professional who can engage in the installation, design, debugging, maintenance, technical transformation, product development and technical management of power supply, all kinds of electrical equipment, electrical control and automation systems.
The main courses offered are: advanced mathematics, engineering mathematics, English, computer culture foundation, C language programming, electrician foundation, analog electronic technology, digital electronic technology, motor drag foundation, power electronic technology, automatic control system, single chip microcomputer and interface technology, power supply technology in factory, electrical control technology in factory, PLC technology and application, automatic detection technology, computer control technology and so on. The main practical links are: metalworking practice, electrician practice, course design of power electronics technology, course design of electrical control, graduation practice (design) and so on. After graduation, students can work in the fields of power plants, power supply systems, electrical engineering and automation in enterprises and institutions, and can also work in the construction, equipment maintenance, overhaul, debugging, technical transformation and sales of power supply projects, automation instruments and electrical control systems in user units, service departments and sales departments. This is the electrical automation technology.
We learned a lot during the production practice. The school also aims to cultivate students' ability and methods to observe and solve problems and learn from production practice. Through this production practice, I learned the technical management knowledge of electrical equipment operation, the manufacturing technology knowledge of electrical equipment and practical knowledge that I couldn't learn in school. In the process of learning from the workers, we have developed a fine style of hard work and plain living. In production practice, I realize that strict discipline and unified organization and coordination are the needs of modern mass production, and are also necessary for our contemporary college students, thus further improving our organizational concept. I think there is a sentence in the company's corporate culture that well summarizes all the contents of technical work-"Research, experiment, design, manufacture, installation, use and maintenance are seven major events, and technicians must go well all the way!" .
I think the "seven major events" mentioned here are all technical activities. Some people think that only the research and design of some high-tech things are truly technical activities, and despise installation, use and maintenance, thinking that the technical content is low or even no technical content. This view is one-sided and wrong. From a philosophical point of view, it is an idealistic view. Practice is the basis of theory, and theory is created by summing up in practice to guide practice. Testing, manufacturing, installation, use and maintenance are our practical work. It's like a computer. In order to make it run normally, hardware and software are inseparable and indispensable. Hardware is the foundation of software, and software is the soul of hardware. Undoubtedly, as a new employee who just left school, I still lack practical experience, and what I learned at school is more theoretical knowledge. Therefore, it is my great honor that the superior leaders can give me this workshop internship opportunity, so that I can really understand the technical work in practice and make up for the shortcomings in practical experience. Only when problems are found in practice can they be solved.
The following mainly reports some problems I encountered during debugging and their solutions. For general problems, such as whether the switch of the distribution box is wrongly connected or not properly installed, it can be easily solved by visual observation; For some occasional and special problems, it takes more time in the debugging process. You need to think positively, consult experienced employees, conduct various tests and experiments by yourself, and sum up the problems carefully after solving them, so as to know why. In addition, I think the circuit wiring principle of rectifier motherboard is very important for mastering the maintenance process, but many maintenance personnel simply don't understand it.
Through this production practice, we have learned and mastered the main structure, production technology and technological process of the substation. Main tools and equipment used; Technical data of product production and use; Production organization and management, etc. To deepen the understanding of basic theories such as working principle, design and test of substation. Make us understand and master the working principle and structural knowledge of substation. It lays a good foundation for further studying professional courses and engaging in research and design in this field.
Experience of automatic production practice The second production practice in 2020 is an important practical teaching link combining teaching with production practice. In the process of production practice, the school also aims to cultivate students' ability and methods to observe and solve problems and learn from production practice. Cultivate our spirit of unity and cooperation, and firmly establish our sense of group, that is, individual wisdom can only be brought into full play if it is integrated into the group.
Through this production practice, I learned the technical management knowledge of electrical equipment operation, the manufacturing technology knowledge of electrical equipment and practical knowledge that I couldn't learn in school. In the process of learning from the workers, we have developed a fine style of hard work and plain living. In production practice, I realize that strict discipline and unified organization and coordination are the needs of modern mass production and are also necessary for our contemporary college students, thus further improving our organizational concept. Through production practice, it has played an important role in consolidating and deepening our theoretical knowledge, cultivating our ability to work independently and enhancing our labor viewpoint.
Since X in 2020, I have been admitted to xx Telecom Equipment Manufacturing Company as an intern. The main contents of the work are assembly, wiring, wiring and debugging. The assembly, wiring and wiring mainly involve PR2000CH-6S high-resistance DC distribution board, PR2000CH-6M high-resistance DC distribution board, PRD 100AC distribution board, PRS3004 integrated rack, PRTE500 rack, etc. Debugging mainly includes static debugging and high voltage test of SMPS 1000, SMPS2000, SMPS3000, SMPS6300, SMPS0500, SMPS0704 and other modules. The debugging process should be carried out in strict accordance with the manual of electrical debugging procedures, and problems should be found and solved step by step. In addition, the welding of circuit boards, the production of wires, the assembly of modules, the installation of empty plugs, etc. are also done, mainly involving pressure plates, rectifier plates, control boards, temperature display circuit boards, crystal oscillator rising limits and so on.
I think there is a sentence in the company's corporate culture that well summarizes all the contents of technical work-"Research, experiment, design, manufacture, installation, use and maintenance are seven major events, and technicians must go well all the way!" . I think the "seven major events" mentioned here are all technical activities. Some people think that only the research and design of some high-tech things are truly technical activities, and despise installation, use and maintenance, thinking that the technical content is low or even no technical content. This view is one-sided and wrong. From a philosophical point of view, it is an idealistic view.
Practice is the basis of theory, and theory is created by summing up in practice to guide practice. Testing, manufacturing, installation, use and maintenance are our practical work. It's like a computer. In order to make it run normally, hardware and software are inseparable and indispensable. Hardware is the foundation of software, and software is the soul of hardware. Undoubtedly, as a new employee who just left school, I still lack practical experience, and what I learned at school is more theoretical knowledge. Therefore, it is my great honor that the superior leaders can give me this workshop internship opportunity, so that I can really understand the technical work in practice and make up for the shortcomings in practical experience.
It is an honor to be a member of the company. Xx Telecom Equipment Manufacturing Co., Ltd. is a united whole, and each employee has his own post. Companies need to arrange positions according to their own needs for faster and better development and personal circumstances. There are technical work, marketing work, management work and other jobs. Any link that goes wrong is not allowed. Therefore, I think every job is very important. As a technical employee in electrical control in the future, I will always adhere to the principle of "seven things consistent system" proposed by the company. Technicians don't just wire, wire, debug and assemble, but they don't know R&D, design and programming. My understanding of the company's development, xx telecom equipment manufacturing company has been in a period of rapid development in recent years since it entered the solar energy industry through industrial restructuring. It can be seen from Mr. Li's work report that there is a huge gap between the domestic and international demand of semiconductor silicon germanium materials and the current market supply. Therefore, the solar energy industry, as a kind of pollution-free clean energy, has huge market potential and provides a broad space for the company's development.
At the same time, it also found some problems in company management and technology.
Only when problems are found in practice can they be solved. The following mainly reports some problems I encountered during debugging and their solutions. For general problems, such as whether the switch of the distribution box is wrongly connected or not properly installed, it can be easily solved by visual observation; For some occasional and special problems, it takes more time in the debugging process. You need to think positively, consult experienced employees, conduct various tests and experiments by yourself, and sum up the problems carefully after solving them, so as to know why. In addition, I think the circuit wiring principle of rectifier motherboard is very important for mastering the maintenance process, but many maintenance personnel simply don't understand it.
Finally, some suggestions on the technology and management of the company are put forward:
1) At present, the electrical control cabinet equipment independently developed, designed and produced by the company is relatively old. Considering the company's long-term development and economic benefits, I think we should improve the control scheme of electronic control products and launch our own new products.
2) In the process of wiring, wiring, debugging and installation of the cabinet, I think mechanical personnel and electrical personnel should strengthen communication and cooperate with each other to complete the work tasks faster and better and improve production efficiency.
In the production workshop, I was the first in the cable class. After all, it was the first time, so it was awkward and laborious at first. However, with the care and help of my colleagues and classmates, I have made continuous progress and growth, and I have fully felt the unity and warmth of the company's big family. So I decided to stick to it no matter how hard and tired I am, so I feel much easier to work. With the guidance and help of my master, I quickly adapted to this job. After these days of transition, I have mastered the steps of making cables and some basic precautions. But I know little about the relevant professional knowledge, so I humbly consult the master and read the relevant books myself, and study them carefully, and finally the problem has been solved well.
During the internship in the workshop, although sometimes the work is very hard and tired, I realized the professional technology in practice and accumulated practical technical experience. Production practice is an important practical teaching link arranged by Baiyun University to train high-quality engineering and technical personnel, and it is an important way to combine teaching with production practice and theory with practice. Its purpose is to train our professional knowledge and talent quality through internship, so as to lay a good foundation for going to work as soon as possible after graduation. Through production practice, we have learned and mastered the main structure, production technology and technological process of various electric cabinets. Main tools and equipment used; Technical data of product production; Production organization and management, etc. To deepen the understanding of the basic theory of AC -DC converter, such as working principle, design and testing. It enables us to understand and master the working principle and structure of AC -DC conversion. In order to further study professional technology, lay a good foundation for wiring, wiring, debugging and installation in this area.
In this production practice, we not only deepened our understanding of what we have learned, but more importantly, we corrected our outlook on labor and improved our ability to work independently.
Finally, I have at least the following problems to solve.
1, lack of work experience
Because of lack of experience, many problems can't tell the priorities, and some training or learning can't find the key points. As the internship goes on, I think I will gradually accumulate experience.
2. Work attitude is still not positive enough.
At work, I can only complete the assigned work. Although you can take the initiative to ask for assignment when there is no work task, you may relax and not take the initiative to learn when there is no work to do. This is mainly because laziness is at work. I will try my best to overcome inertia in the future. I will do my homework when I have no work tasks, and study independently when I have no work tasks.
I don't study hard enough at work.
I chose it myself, because in my opinion, only the technology recognized by the market is valuable, and I also feel that I am more suitable for communicating with people. I firmly believe that through this period of internship, the practical experience gained from it will benefit me for life, and it will be confirmed in the actual work after graduation. I will continue to understand and experience the knowledge I have learned in my internship, and I also hope that I can apply the theoretical knowledge and practical experience I have learned to my future practical work, fully display my personal value and life value, and work hard to realize my ideal and bright future.
In short, in the past year, with the care and training of teachers and colleagues, I have studied hard and worked hard, and my ability has been greatly improved, and my overall quality has also been developed in an all-round way, but I know I still have some shortcomings and deficiencies. In my future work and study, I will be more strict with myself, learn from excellent colleagues with an open mind, continue to work hard to correct my shortcomings and deficiencies, and strive for greater progress in my thoughts, work, study and life.
Automatic production internship experience I entered the senior year in 2020, and I started my long-awaited production internship. Production practice is an important part of our study of automation specialty, and it is a good opportunity to combine the theoretical knowledge learned in class with practice, which is very helpful to strengthen our knowledge and test the mastery of what we have learned. During the four-day production practice, we went to four factories, including xx Water Purification Plant, xx Tobacco Machinery Plant, xx Shougang Plate Plant and xx Port Authority. During the internship, we learned a lot of knowledge that was not in the textbook, and really benefited a lot.
The production practice lasted about ten days, and I went to tap water purification plant, xx tobacco machinery factory, xx Shougang plate factory director and xx port authority successively. After this internship, I came into contact with the real factory and really felt the work in the industrial field. I only studied before, and I have never been exposed to factories in the real life of school. When I first entered the factory, I didn't adapt to some harsh environment at first, and then I gradually adapted, so this internship gave me a very good exercise opportunity.
Let me not be like a child who knows nothing and is afraid of everything when I really go to work in the future. I summed up that some people are simple from theory to practice, but it is not easy to achieve it. In the real factory environment, some theoretical knowledge is completely unnecessary, and these environmental factors are basically ignored in textbooks, so we should seize every opportunity to practice by ourselves, feel the differences, feel the fun and enhance our hands-on ability. Although I didn't get a real chance to do this internship, I also witnessed the operation of some automation equipment and personally felt the atmosphere of the production site. This is also an experience, a kind of growth. With this internship, I believe it will definitely help me when I look for a job in the future. Here, I would also like to thank the teachers who lead us in our efforts, accompany our classmates in the scorching sun and always worry about our safety. Teachers have worked hard for you.

Fourth, the internship content
On October 5th, 65438/KLOC-0, we arrived at xx Yixin Technology Co., Ltd. At the beginning of the internship, Li Shifu, an employee of the company, led the whole class to visit the company's workshop professionally. In the workshop, Li Shifu gave a professional and technical explanation to the questions raised by the students during the visit. During the visit, Li Shifu introduced in detail the new technologies and new equipment adopted and developed by my major in their workshop, which deepened my professional knowledge. Each workshop has its own functions, but they are closely related. For example, to make a rolling mill requires the cooperation of all workshops, from the initial drawing design to the final parts assembly, there is no mistake, and it is precise and accurate.
For some short and fresh terms introduced by Li Shifu, such as copper bus master and slave controller PID, students are full of doubts and put forward their own questions. Li Shifu patiently explained our expertise and knowledge. Electronic products are upgrading rapidly, and he gave a very detailed introduction to what technology research and development needs, what college students need, and what the professional development prospects are. Because he has worked in this company for quite a long time, he knows a lot about college students, puts forward some requirements for the skills we should master in universities, and dispels doubts about the mastery of professional knowledge and the position in their products, which has benefited me a lot.
Five, internship experience and experience
Through this internship, I learned a lot of things that I couldn't learn in class, as if I suddenly became mature, understood the truth of being a man and doing things, and understood the significance of learning. I saw clearly my life direction, and also made me realize that engaging in electronic work should support a careful and serious work attitude, have a peaceful mind and innovative spirit, and have a heart ready to accept tests to meet the unknown world.
During the internship, I was modest and cautious, listened carefully to the guidance and explanation of relevant technicians, and was able to observe carefully, experience personally, think independently and analyze comprehensively. I also cultivated my patience and quality, and I was able to follow the instructions. I feel the pleasure of asking questions and solving problems. I also like my major more, and I am no longer confused.
This internship made me feel the application of what I have learned for the first time. The combination of theory and practice has opened our eyes, and it is also a preliminary test of what we have learned before! Because practice is the only criterion for testing truth. This internship really benefited me a lot in my future study and job hunting. In a short period of half a day, I have initially completed the re-understanding from rationality to sensibility, which has also given me a preliminary understanding of this society and inspired me to grasp the direction in the future.
In a word, as a sophomore, this professional practice undoubtedly makes me look at the automation major from a brand-new perspective, and it will certainly help my future development and promotion. I will take this internship as the starting point of my life, and constantly ask myself to improve myself and do better in my future work and study. Finally, I want to use Qu Yuan's words as a conclusion to encourage you: The road is long and Xiu Yuan is Xi, and Xiu Yuan is Xi, so I will go up and down for it.
