毕业设计是对毕业生所学专业知识的一个总结、归纳、深化的过程，其中包含了

Graduation design is a process of summarizing, summarizing and deepening the professional knowledge learned by graduates, which contains things we need to strengthen from time to time: such as the ability to analyze and solve problems, the ability to consult the literature, the ability to coordinate editing and the ability to summarize experience and many more. During the several weeks of graduation design, we got the instructor's careful guidance and care, especially in the design process of the subject, the instructor spent a lot of time and energy on various technical problems and doubts Answering for us, let me have a new in-depth and comprehensive improvement of the knowledge of the microcontroller control system in this process, and can gradually combine the theoretical knowledge learned in the textbook with the actual problems in production, so Going into the society to solve practical problems encountered in the work laid a good foundation. Here, I would like to express my most heartfelt thanks to instructor Wang Yujie! I also thank all the academic teachers for the past four years, and thank the authors of the materials referenced on the Internet. It is your grandfather who is selfless. The past and present help have made my production not take too many detours. <br>Thanks again to Teacher Wang Yujie for his careful guidance! <br>Due to the limitation of time and knowledge level, there are inevitable flaws and errors in the design. I sincerely ask all review teachers to correct me carefully.

Graduation design is a process of summing up, summarizing and deepening the expertise that graduates learn, and contains things we need to strengthen from time to time: the ability to analyze problem-solving, access to literature, the ability to co-ordinate editing, and the ability to sum up experience. During the weeks of graduation design, we have been carefully guided and cared for by the guidance teacher, especially in the design process of the subject, the guidance teacher has spent a lot of time and energy to answer each other for us, let me in the process of the microcontroller control system knowledge has a new in-depth and comprehensive promotion, and can gradually learn in the textbook theoretical knowledge and practical problems in production, So as to step into the social work to solve the practical problems encountered to lay a good foundation. Here, to the guidance teacher Wang Yujie expressed the most heartfelt thanks! Also thanks to all the teachers over the past four years, and to the authors of the information referenced on the Internet, it is your selfless, past and present help, so that my production did not take too many detours.<br>Once again to Wang Yujie teacher's careful guidance to thank!<br>Due to the time and knowledge level constraints, the design will inevitably appear leakage and errors, I urge you to review the teacher carefully.

Graduation project is a process of summing up, summing up and deepening the professional knowledge of graduates, which includes the things we need to strengthen from time to time, such as the ability to analyze and solve problems, the ability to consult literature, the ability to coordinate editors and summarize experience, etc. During the several weeks of graduation project, we got the careful guidance and care of the instructor, especially in the design process of the project, the instructor spent a lot of time and energy to answer all kinds of technical problems and doubts for us one by one, which made me have a new in-depth and comprehensive improvement in the knowledge of single-chip microcomputer control system in this process, And can gradually combine the theoretical knowledge learned in the textbook with the practical problems in production, so as to lay a good foundation for solving the practical problems encountered in the future. Here, I would like to express my heartfelt thanks to my tutor Wang Yujie! Thanks to all the academic teachers in the past four years, and thanks to the authors of the reference materials on the Internet. It is your selflessness, past and present help that makes my production not go too far.<br>Once again, I would like to thank Mr. Wang Yujie for his careful guidance!<br>Due to the limitation of time and knowledge level, mistakes and mistakes will inevitably appear in the design. Please review and correct them carefully.
