【正文】 I 畢業(yè)設(shè)計(jì) 中文題目：基于單片機(jī)的輸液監(jiān)控系統(tǒng)設(shè)計(jì) 外文題目： DESIGN OF INFUSION MONITORING SYSTEM BASED ON SINGLE CHIP II 摘要 輸液是醫(yī)院常用的治療手段，傳統(tǒng)輸液過程中存在著輸液速度不精確、需要人工監(jiān)護(hù)等弊端。本文的目的就是設(shè)計(jì)一種輸液監(jiān)控系統(tǒng)以解決此問題。 本文設(shè)計(jì)的輸液監(jiān)控系統(tǒng)，實(shí)現(xiàn)了對(duì)輸液速度的檢測與控制，實(shí)現(xiàn)了對(duì)儲(chǔ)液瓶中液面體積的檢測報(bào)警，并且動(dòng)態(tài)顯示輸液速度。使用者可以通過 PC 設(shè)置輸液速度，系統(tǒng)將自動(dòng)對(duì)輸液 速度進(jìn)行控制。此外系統(tǒng)還實(shí)現(xiàn)了多機(jī)通信， 即一個(gè)主站控制多個(gè)從站和主從機(jī)之間的數(shù)據(jù)傳輸。當(dāng)輸液結(jié)束或輸液速度發(fā)生異常時(shí)，從站使用發(fā)光二極管和蜂鳴器進(jìn)行報(bào)警，并將報(bào)警信號(hào)通過串行口傳送至主站，主站通過監(jiān)控軟件和蜂鳴器實(shí)現(xiàn)聲光報(bào)警。在整體方案設(shè)計(jì)中，在保證設(shè)計(jì)系統(tǒng)能達(dá)到的使用要求的精度和穩(wěn)定度的前提下，考慮到系統(tǒng)的輕便性、實(shí)用性、可靠性，對(duì)電路系統(tǒng)進(jìn)行了優(yōu)化。 本設(shè)計(jì)基本完成了預(yù)想功能，并指明了以后的研究方向和工作重點(diǎn)。 關(guān)鍵詞：單片機(jī)； PID；步進(jìn)電機(jī)； CAN 總線； PC III Abstract Transfusion monly used as treatment in hospital， but there were some problems， such as inaccurate， need transfusion of artificial guardianship， etc． The goal is to design a transfusion monitoring system in order to solve those problems． The infusion monitoring system design by this paper,actualize the infusion rate of test， the control of reservoir fluid bottle volume detection alarm and dynamic display of transfusion speed． Users can through the PC to control transfusion the system also actualize multimachine munication， that is， a master station to control multiple machines from a station and the master． slave data transmission between． When the infusion end or infusion speed abnormal， slave light—emitting diodes and buzzer to alarm， and will alarm signals through serial transmission to the master， stood by monitoring software realization and buzzer soundlight alarm． In the overall program design,in ensuring the use of design systems to achieve the required accuracy and stability of the premise， taking into account the system’s portability，practicality， reliability， electrical systems were optimized． Finally,the infusion monitoring system design by this paper， and point out future research directions and priorities． Keywords： single chip； PID；
