摘要
输液是医院常用的治疗手段，传统输液过程中存在着输液速度不精确、需要人工监护等弊端。本文的目的就是设计一种输液监控系统以解决此问题。
本文设计的输液监控系统，实现了对输液速度的检测与控制，实现了对储液瓶中液面体积的检测报警，并且动态显示输液速度。使用者可以通过PC设置输液速度，系统将自动对输液速度进行控制。此外系统还实现了多机通信， 即一个主站控制多个从站和主从机之间的数据传输。当输液结束或输液速度发生异常时，从站使用发光二极管和蜂鸣器进行报警，
并将报警信号通过串行口传送至主站，主站通过监控软件和蜂鸣器实现声光报警。在整体方案设计中，在保证设计系统能达到的使用要求的精度和稳定度的前提下，考虑到系统的轻便性、实用性、可靠性，对电路系统进行了优化。
本设计基本完成了预想功能，并指明了以后的研究方向和工作重点。
