It can reduce the pressure of staff, improve the working efficiency of medical staffs. Intravenous infusion is a mon clinical treatment，the treatment effect in the vein of the input,this topic is the design method of the intelligent infusion system, the scheme is based on AT89S51 control. This system operation is simple, started fast, has an alarm function and convenient centralized control, is of great significance in modern medical enterprise，promote the development of intelligent medical business automation，is conducive to improving the quality of medical care. The main function of this subject: the circuit for collecting the droplet velocity，droplet velocity can be set and pared, can display the drop speed and the rest of the infusion time。 can set up their own drop speed。 in the infusion of remaining liquid volume is lower than the set value, the automatic alarm, or infusion process there are special circumstances can also alarm. Part of the research blank infusion system added to the direction, have important significance for analyzing the structure of the equipment and electronic design research。 through theoretical analysis, a very good analysis of the theory and practice basis of the infusion system. The results of research on this to picprovides abundant information for the study of transfusion system.Key words: 51MCU hospital infusion system transfusion monitoringIII目 錄摘要 ....................................................................IAbstract ...............................................................II緒論 ...................................................................11 課題的背景和意義 ....................................................2 醫(yī)療輸液監(jiān)控系統(tǒng)設(shè)計(jì)背景 ..........................................2 醫(yī)療輸液監(jiān)控系統(tǒng)設(shè)計(jì)意義 ..........................................2 系統(tǒng)設(shè)計(jì)的關(guān)鍵問題 ................................................32 系統(tǒng)方案設(shè)計(jì)與論證 ..................................................4 系統(tǒng)硬件結(jié)構(gòu)設(shè)計(jì)方案 ..............................................4 點(diǎn)滴速度測量電路方案 ..............................................4 液面檢測電路方案選擇 ..............................................5 電機(jī)控制滴速電路 ..................................................6 顯示器接口電路方案 ................................................6 鍵盤接口電路方案 ..................................................7 單片機(jī)型號(hào)的選擇與論證 ............................................73 輸液系統(tǒng)各模塊硬件設(shè)計(jì) .............................................11 控制電機(jī)模塊設(shè)計(jì) .................................................11 數(shù)據(jù)采集模塊 .....................................................12 電源模塊 .........................................................16 聲報(bào)警模塊 .......................................................16 復(fù)位電路 .........................................................17 顯示模塊 .........................................................17 鍵控模塊 .........................................................184 系統(tǒng)軟件及框圖設(shè)計(jì) .................................................20IV 滴速檢測子程序 ...................................................20 電機(jī)控制子程序 ...................................................21 鍵盤程序 .........................................................22結(jié)論 ..................................................................24致謝 ..................................................................25參考文獻(xiàn) ..............................................................26附錄一總體設(shè)計(jì)原理圖 ..................................................271緒 論隨著科技的進(jìn)步，越來越多的地方需要用到對液體的流量或者滴速進(jìn)行控制，如人工腎機(jī)的
