Abstract
After understanding the theory, the standards, the advanced and the disadvanced of the micro-injection pump, this article will put emphasis upon designing for its software.The system of the micro-injection pump adopt STC89C58 as a controller chip,to reduce cost; and use the C language to program for improving efficiency;and to provide a convenient way for users, we use a lcd screen as a man-machine device,that can display menus and commands in Chinese.
This article was divided by six parts ,and will show you as list as following:
The first chapter will introduce the background and development of the micro-injection pump in the world.
The second chapter will analysis fuctions, standards and requirements of the micro-injection pump. And according to that, we will give out a design of its controller’s system.
The next chapter will tell you some hardwares and devices, that was refered in software designing.It will say something about key scanning,lcd screen driving and step-motor driving,and so on, in order to analysis fuctions of software.
The fourth chapter is the most important part in this article. This part will introduce the process of software designing, and some fuctional modules and how it carry out.
The fifth chapter will debug the software that already completed.
The last part is conclusion about this graduating design,including some reference literatures and program list.
