Through these two weeks' training, we learned the programming method of hand-held programmer and how to program, write, delete and modify. I hope everyone will mention it more in the future study process. Ni Zexu and I are mainly responsible for program design and debugging. The first project is relatively simple. There is only one small problem, which we will solve soon. Compared with the first project, the second project is much more complicated and difficult, and it is also the first time that we really contact and use a three-phase alternator. There are many problems in the editing of ladder diagram, which leads to the failure of the first debugging. There was a slight problem in the loop between completing the operation and restarting the operation. After we monitor and check the ladder diagram, we find that the loop conflicts with the above programming. Later, we adjusted it and the debugging finally succeeded. In terms of wiring, we encountered difficulties in the star-delta conversion, and finally succeeded through our unremitting efforts.

Through this training, we learned a lot, and at the same time, we realized that we should learn more. From program design to writing, drawing, debugging, revising and perfecting, to the final training report, everyone has invested time and energy to help his teammates, so teamwork and mutual assistance between teammates are very important. Through practical training, you can have a deeper understanding of your major, your ability and what you have learned, and you can also constantly improve and perfect yourself in future study. The wiring of the training platform is chaotic, which is also the main reason for our wiring inspection difficulties, leading to some wiring problems.

On the whole, this training is quite successful, and both the individual hands-on ability and the team cooperation ability have been well exercised. In the process of training, the teacher also gave us many simple and practical skills. We also know that it is very important to do a good job in a project. Whether from the perspective of visitors or from our own perspective, the degree of beauty is also essential.

Fan training summary

After two weeks of training, I learned a lot. During these two weeks, my team and I completed two training projects. First of all, I learned teamwork. Without the efforts of our group, there would be no final result. In this training, I am responsible for reporting and drawing. This is my first contact with Visio. Through the teacher's teaching, I learned how to complete some circuit diagrams and distribution diagrams of the project, which benefited me a lot.

In this training, I have a further understanding of the use of PLC. Although we have a clear division of labor, when programming or debugging, everyone participates and learns from each other's shortcomings. I was not very skilled in the preparation of some PLC ladder diagrams before, and the analysis of the project was not accurate, but with the help of teachers and team members, I still know a lot, but I still have my own shortcomings. Through practical training, I further affirmed my own shortcomings, but I have a clearer understanding of what I have learned. I believe that in the future study, I will make up for my own shortcomings, take the initiative to play team spirit, and strive to improve in other aspects, including writing programs.

With everyone's help, the training was a complete success, and we all got a good exercise, whether it was teamwork or hands-on operation. Through this training, we have a further desire for PLC knowledge. I believe that sweat will not be wasted, and our future success is obvious to all.

Training summary Fan Wensan

The two-week training course is finally over, and I have learned a lot of new knowledge in this training. In this training, we all adopted a step-by-step programming method. This method is convenient, fast and clear, and it is also the best programming method we have mastered, and it is not easy to make mistakes. In this training, we cooperated together, and we finished programming, drawing, wiring, debugging and making training reports one by one. The steps are clear. Although the speed of completing the second project is a bit slow, we still finished it. When doing the second training project, we all felt a little difficult and challenging, so we were more United and cooperative when doing the second training project, but even so, we still made mistakes. There are some loopholes in our program during compilation, which leads to that it can only run normally once during debugging. Later, it was found that the reason was that the program made a mistake in the loop. After our adjustment, it finally ran perfectly, which also delayed us a lot of precious time and directly led to the second. In the second project, a three-phase asynchronous motor is used, and the operation of a motor has to be converted into a star triangle, which brings us great trouble in wiring, but we finally completed the correct wiring by looking up information and asking classmates. Through this internship, I have a correct understanding of my ability and our major. In future operations, we should learn this lesson and not make similar mistakes again. In the future study, we should strive to improve our ability, constantly improve ourselves and be an excellent person.
