In order to solve the common problem of monitoring infusion condition in the artificial way, a monitoring system based on electro-optical examination technology and wireless communication technology is designed, the system which uses the non-contact detection technology to achieve information on the droplet and surface detection can achieve the condition monitoring of infusion effectively. When the warning message appears, the system can realize promptly and accurately; Futhermore, with the terminal interface of computer, information of current infusion can be achieved, and taking remote control of slaves is available. With the system, intensity of health care personnels and medical errors can be reduced effectively, so that health care personnels could have more time to pay attention to their medical work and patient will be more time left. Besides, the system can be compatible with the existing information system of hospital, and hospitals informationization and humanization being fully displayed.Key words： Non-contact detection technology； Intravenous infusion; Remote control； Real-time monitoring五邑大学本科毕业设计五邑大学本科毕业设计( (论文论文) ) 注意本栏字体为注意本栏字体为“隶书隶书”III目 录摘 要.IAbstract.II第 1 章 绪 论.11.1 系统的研究背景.11.2 国内外现状及发展状态.11.3 系统的研究意义.21.4 本章小结.2第 2 章 系统总体设计.32.1 系统概述.32.2 系统结构.32.3 系统主体方案设计.32.3.1 液滴信号采集方案.32.3.2 液滴信号处理方案.42.3.3 液面信号采集方案.42.3.4 数据显示方案.52.3.5 数据输入方案.52.3.6 串行通信方案.52.4 系统设计原则.52.5 本章小结.6第 3 章 系统硬件设计.73.1 系统硬件设计原则.73.2 系统硬件电路设计.73.2.1 液滴检测电路设计.73.2.2 液面检测电路设计.83.2.3 按键电路设计.
