摘要
目前，我國大多數(shù)醫(yī)院臨床輸液普遍采用人工方法,所需人力資源巨大,且不易管理。為此，我們研制一智能輸液泵系統(tǒng)。雖然目前市場上已經(jīng)出現(xiàn)了此類產品，但由于價格和精度等問題，在國內還沒有被推廣使用。微量泵有單、雙和多通道之分，多通道可分別對多個通道設置、保存參數(shù)，本次畢業(yè)設計準備制作一單通道微量泵,將降低微量泵的生產成本和提高控制精度,這有助于微泵的推廣應用。
在了解了微量注射泵的工作原理，性能指標和優(yōu)缺點后，本文著重進行了微量注射泵的軟件設計。微量注射泵控制系統(tǒng)采用單片機（STC89C58）作為主控芯片，降低生產成本；利用C51進行軟件編程，提高編程效率；利用液晶屏LCD作為人機界面，顯示中文菜單和命令，為用戶提供了方便。
本文共分為緒論、正文（四章）和結論等六部分。
緒論主要介紹了本課題的背景和國內外發(fā)展現(xiàn)狀等情況；
第二章介紹了微量注射泵控制系統(tǒng)的分析和總體方案的設計，包括微量泵要實現(xiàn)的功能以及應達到的性能指標等要求，根據(jù)具體的要求分析、選擇合理的控制方案；
第三章簡單介紹在本軟件設計中涉及的硬件設備，包括按鍵掃描處理、LCD顯示屏驅動、步進電機驅動等硬件介紹說明,主要用于軟件功能的分析；
第四章是本文的重點，在這一章節(jié)中詳細地敘述了微量注射泵的軟件設計過程，以及各軟件模塊的功能和實現(xiàn)方法；
第五章介紹系統(tǒng)各軟件模塊的調試方法，以及系統(tǒng)整體調試的情況；
第六章是本次畢業(yè)設計的結論、參考文獻和程序附錄。

Abstract
Currently, the hospital used microinjection pump commonly known as "micro-pump" in the operating room to use more wards, to some extent alleviate the medical staff in the labor intensity, to provide sustained delivery, avoided a drug delivery and other peak effect on the human liver and kidney and other organ damage, greatly reducing the total amount of medicinal, to bring the Gospel of patients to medical staff convenience. As micro-pump to higher prices and promotes the use of domestic prices of a few thousand to 10,000 yuan, and import prices from 20,000 to 50,000 yuan,in a certain extent, limited its use, and hence the price factor is whether it can use its root causes. Clinical mercury sphygmomanometer in each of about 100 yuan, at all levels of medium and small hospitals generally use is a good proof. Therefore, produced a small microinjection pump is very meaningful.
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 sixth part is conclusion about this graduating design,including some reference literatures and program list.
Key word : Micro-injection pump control system software designing MCU
