The experience of automatic cognitive practice. I have been practicing for x days and I am deeply touched. First of all, I saw the irreplaceable influence of automation on production and life. I think automation has really liberated and developed productive forces, liberated production from the bondage of labor, and broken the most important limiting factor. He can work without rest. For example-the water treatment system of a water plant. The application of automation in life has also brought us great convenience. For example, we visited the substation and the Internet of Things base. The staff only need to monitor by computer in the office, deal with problems in time or send information to inform relevant personnel, which reduces the probability of accidental factors caused by misoperation when people enter the place. Another example is automatic doors and ATMs, which have brought convenience to our lives to a great extent. Secondly, this production practice has strengthened my belief in continuing my study and further study. Through this production practice, I saw a bright and broad prospect of automation. With the development of the times, almost all links will be automatically controlled. There are still many automation technologies to be studied in our region, and the investment and construction in automation will be immeasurable. It will be a correct choice to continue studying in the field of automation.
Finally, China's automation construction still has a long way to go, and it needs our generation to grow up as soon as possible and shoulder the heavy responsibility of building the country. What makes me most sorry and sad is that the core equipment of the three industrial factories we visited were imported from abroad. The abrasive tools of the electric appliance factory are imported by technical cooperation, the membrane treatment system of the water plant is purchased from X, and the production and distribution of tin firewood are imported. Even our self-developed tin diesel engine has no manufacturing machines or parts that meet the specifications, and even the best design is just empty talk. Just like Einstein never read, but genius is useless. We should not only be excited about the superficial prosperity, but also see the backward situation of automatic auxiliary distribution in China and work hard for it for life. Before, my relatives and friends said that studying abroad was very hard. Foreign countries have high requirements and advanced technology, so it is difficult to learn and master. Studying in China is relatively easy. After that visit, I strengthened my belief that I want to study abroad. Because our automation field needs these advanced technologies and real talents. From now on, I will study harder and contribute to the automation construction of the motherland.
Thanks to the college for arranging production practice for us, and to-and-X for its hard guidance.
According to the teaching plan of the school, I started my internship in xx company from 20xx 10. The main information of the work is assembly, wiring, wiring and debugging. Assembly, wiring, wiring and debugging shall be carried out in strict accordance with the manual of electrical debugging procedures, and problems shall be solved step by step when found. In addition, the work of welding the circuit board, making wires, assembling modules and installing empty plugs is also done, which mainly involves the pressure plate, rectifier plate, control board, temperature display circuit board, crystal rise limit and so on.
Yantai Telecom Equipment Co., Ltd. is a United whole, and each employee has his own post, including interns. Companies need to arrange jobs 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, Yantai 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. There is a huge gap between the demand for semiconductor silicon germanium materials at home and abroad and the current market supply. Therefore, the solar energy industry, as a kind of pollution-free clean energy, has huge market potential and brings a broad space for the company's development.
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 on campus. 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 the theoretical knowledge we have learned, cultivating the potential of our independent work and strengthening our labor viewpoint.
I think there is a sentence in the company's corporate culture that sums up all the information of technical work well-"Research, experiment, design, manufacture, installation, use and maintenance are seven major events, and technicians should go well all the way!" . I think the "seven major events" mentioned in it are all technical work. 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 an intern who just left school, I still lack practical experience, and what I learned on campus 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 carefully, consult experienced employees, conduct various tests and experiments yourself, and sum up the problems carefully after solving them, so that you can 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, I would like to make some suggestions on the technology and management of the company:
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, it was the first time for me to take a cable class. After all, it was the first time, so I was clumsy and hard at first. But with the care and help of my colleagues and classmates, I made continuous progress and growth, and I fully felt the unity and warmth of the company's big family, so I decided to stick to it even if I was bitter and tired, so I felt a lot easier to work. With the guidance and help of the teacher, 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 and an important way to combine campus teaching with production practice and integrate theory with practice. Its purpose is to train our professional knowledge and talent quality through internship, so as to lay a good foundation for taking up jobs and becoming a backbone 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 data, deepen the understanding of basic theories such as working principle, design and test of AC -DC conversion. 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 revised our concept of labor and improved our potential for independent work.
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 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 hope 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 studied hard and worked hard, and my potential was greatly improved, and my comprehensive quality was also developed in an all-round way, but I understand that there are still 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 cognitive exercise experience 3 1. Practical purposes and tasks
Cognitive practice is an important part of practical teaching and one of the main means to realize the cultivation of applied talents in this major. Through practice, students can have a comprehensive and perceptual understanding of the production process and main equipment of industrial enterprises and the application of automatic control in industrial production, thus improving their enthusiasm and initiative in learning professional knowledge.
Its task is to understand the general situation of factory production, production organization and management, the role of automatic control in industrial production, the production status of factory electrical control equipment, the new technology, new equipment and new direction of electrical control technology, and the roles and responsibilities of engineering and technical personnel and production management personnel in the process of production and testing.
Second, the internship time
Xx year x month xx day -xx year x month xx day
Third, the internship location
Fourth, the internship content
Xx year x month xx day
Today we visited the xx factory in xx Pioneer Park. After x o'clock in the morning, we went to our destination by bus.
Xx Factory is a wholly-owned enterprise under xx Corporation, which was established in xx with a workshop area of about xx square meters. With a registered capital of12 million yuan, it is a professional manufacturer of high and low voltage electrical appliances and complete sets of high and low voltage electrical equipment in electric power, metallurgy, mining, coal, chemical industry and other industries, and is a key backbone enterprise in the electrical appliance industry in Hunan Province.
The factory is divided into two floors. We visited the second floor first. When we went there, workers were working, and a master there introduced us some knowledge about the performance, structure and principle of products, which was limited to professional knowledge, and some things were incomprehensible. But with the perceptual knowledge of these products, the students were full of interest when they visited, and they all had a strong interest in these things they had never seen before. Several of our students went to a wiring worker's workbench to observe her wiring, and only saw that he was skilled, fast and beautiful. Many of us watched it for a long time and praised her wiring skills. We feel that the wires received by the electrician internship before are much worse than this. The students said, we must do more and make what we want beautiful, just like the wires connected by the wiring workers.
After visiting the second floor, we came to the first floor. There are no production workers here, and there are many switches here. I used to think the switch was a very simple thing. Don't you just switch it on and off? Can there be any advanced switches? It turns out that I was wrong. There are many switches. I think so because I have been exposed to simple switches in my life before. Here, we see vsi indoor high-voltage vacuum circuit breaker, kyn28a(gzsi)- 12 indoor AC metal armored draw-out switchgear, vjd medium-voltage sealed vacuum circuit breaker, gcs low-voltage draw-out switchgear and mns low-voltage complete switchgear.
Here I specifically describe some situations of gcs low-voltage draw-out switchgear. I learned from the instructions hanging on that cabinet that this low-voltage draw-out switchgear has two main frames, a fully assembled structure and a partially welded structure; Each function room of the device is strictly separated, and each function room is mainly divided into unit type, bus type and cable type, and the functions of each unit are relatively independent; The horizontal bus is horizontally arranged behind the frame to increase the ability of the bus to resist short-circuit current electromotive force; The cable room adopts the way of up and down incoming and outgoing wires; According to the three-phase five-wire system or three-phase four-wire system; A drawer is a unit, and the size of the drawer is divided into five size series: one unit, two units, three units, one-half unit and one-quarter unit, and the rated current of each unit loop is below 630a. The change of drawer size is only the change of height, its width and depth cannot be changed, and units with the same function can be interchanged.
I also know something about mns low-voltage switchgear, which is suitable for power plants, substations, petrochemical, metallurgical steel rolling, textile and other factories and mines, residential quarters, high-rise buildings and other places, and is used for power conversion, distribution and control of distribution equipment in power systems with alternating current of 50 ~ 60 Hz and rated working voltage of 660v or below.
I have also carefully read the product manual of vsi indoor high-voltage vacuum circuit breaker. It has many advantages, one of which is that its contacts often use butt contacts. Because the distance between the moving contact and the static contact in general vacuum circuit breaker is only as small as 16mm, it is difficult to make contact surfaces with other shapes, and the damage of instantaneous action arc on the straight contact surface is also small. One of the advantages of vacuum circuit breaker is its small size. The moving contact and the static contact should move in an absolute vacuum space. If you make other docking methods, it will increase the size of the circuit breaker itself!
To tell the truth, I don't quite understand the principle of these advanced switchgear. This trip to Kai Guanchang in Jingdian made me more curious about the principle of electrical appliances. Junior year must study hard professional knowledge, determined to engage in the electrical industry in the future, and make their own modest contribution to the electrical cause.
Automatic cognitive exercise experience 4 1. Practical purpose
1. Through the specific circuit diagram, I have mastered the general principles of welding technology, simple circuit component assembly, fault diagnosis and elimination, and radio principle.
2. Be familiar with the basic knowledge and principles of electronic assembly and welding technology, and master the welding process.
3. Understand the knowledge of safe electricity use, learn the essentials of safe operation, cultivate a rigorous work style, develop good work habits, cultivate a correct outlook on labor and life, and cultivate team consciousness and collectivism.
Second, the internship task
1. Students are required to be familiar with the identification, selection principles and testing methods of common electronic components.
2. Students are required to practice and master the correct welding method, be familiar with the selection of welding tools and materials, understand the development of electronic welding technology in industrial production, welding technology and the production process of assembling the whole machine.
3. Students are required to master the basic operation skills of PCB assembly, welding and debugging, and make, install, debug and test the actual products.
4. Students are required to master the basic knowledge and design methods of circuit boards.
Third, the internship content
(1) welding training:
Components: circuit board, wires;
Tools: electric soldering iron, tin wire;
In welding training, the soldering iron is heated first, and then the wires are welded according to the teacher's requirements. Pay special attention to not too much tin when welding, otherwise it will be easy to short circuit. After welding, use multimeter to test.
(2) welding PCB board
Fourth, learning experience.
I learned a lot during the whole internship, which opened my eyes and touched me deeply. Simple welding made me understand the true meaning of life learning. Although the course is over, the study is not over yet. I know that as a college student in the information age, as a high-tech talent trained by the country, it is not enough to operate the mouse only. Basic hands-on ability is the basis and necessary condition for all work and creation. This time, I gained a lot in the one-week electronic technology internship. If all we have learned before is some theoretical knowledge, then this internship has made us experience a real practice. From the simplest identification of resistance and capacitance, as well as the identification, use and detection of various electronic components, to the correct use and welding of electric soldering iron, we can understand the layout and manufacture of pcb board. This is because we feel a sense of freshness and a strong thirst for knowledge rising in our chest.
This internship is undoubtedly a good practice opportunity for us, so I took a more serious attitude from the beginning. No matter from the understanding of the basis of radio broadcasting or the realization principle, the later welding is an improvement for me. The key task of this internship is welding. Because some simple circuit boards have been welded before, it is not difficult for us to weld, but due to the tight layout of electronic components, welding needs to be treated with care. If the welding is wrong, it will take a lot of effort to remove it, and it may not come out. So I dare not neglect at all. However, there was still a little problem in debugging, and the indicator light was a little unstable, but with the help of classmates, it was finally solved perfectly.
This internship made me understand a truth. With the rapid development of modern times, it is not enough to arm our brains with some theoretical knowledge. You also need to dress up your hands with practical operation ability. Only in this way can we live up to the cultivation of the motherland, be a good successor to the motherland and contribute our strength to the motherland.
