通过这次毕业设计，我学到了很多课本上不具备的知识，也锻炼了自己的实践能力，将零散的知识融为一体。经过我长时间的设计和调试，该系统基本上可以实现基于单片机的脉搏计的所有功能。缺点是具体如下：1。硬件的稳定性有待进一步提高；我的综合设计主要涉及硬件和软件两个方面，通过这两个方面提高了我的硬件和软件开发能力。首先，在硬件方面，我对电子产品的开发过程和要做的工作有了基本的了解。基本掌握protel99se原理图法。并设计了一个单片机最小系统，通过开发板的设计和硬件的搭建过程，对51系列单片机的接口有了更深入的了解，熟悉了一些常用的外围电路引脚和单片机的连接方法，如液晶显示液水晶、键盘等，学习了分析问题、解决问题的能力，加深了对所学理论知识的理解和应用，动手能力大大提高，创新意识得到锻炼。

Through this graduation project, I learned a lot of knowledge that I didn't have in the textbook, and also exercised my practical ability to integrate the scattered knowledge. After a long time of design and debugging, the system can basically achieve all the functions of the pulse meter based on single chip microcomputer. The disadvantages are as follows: 1. The stability of hardware needs to be further improved; my comprehensive design mainly involves two aspects of hardware and software, through which my ability of hardware and software development is improved. First of all, in terms of hardware, I have a basic understanding of the development process of electronic products and the work to be done. Basically master Protel99SE schematic method. Through the design of development board and the construction of hardware, we have a deeper understanding of the interface of 51 Series MCU, familiar with some common peripheral circuit pins and MCU connection methods, such as LCD liquid crystal, keyboard, etc., learned the ability to analyze and solve problems, deepened the understanding of theoretical knowledge. And application, hands-on ability has been greatly improved, and innovation awareness has been exercised.<br>
