液体点滴速度监控系统的设计

摘要

随着现代科技的发展，自动化设备已经应用到我们生活中的各个领域，然而传统的医疗输液设备效率较低，因此我们有必要提高医疗设备的自动化水平，给护士输液工作提供方便，给输液病人提供可靠的安全保证。因此本文本着适用、可靠、操作方便、节省劳力、降低劳动强度、提高操作准确性的原则，利用SPCE061A凌阳单片机组成了一个主从局域网络，实现了对液体点滴速度的自动监测与调节，并能实时监测剩余药液。该控制系统由水滴速度检测环节、水滴速度控制环节、显示装置、单片机系统、键盘和报警等系统组成。本文硬件部分用SPCE061A单片机，传感器，直流伺服电动机，键盘，数码管等实现。软件程序使用C语言与汇编语言共同编写。通过软硬件的结合，较好的实现了控制系统的控制要求。此单片机控制系统具有自动化程度高、成本低、体积小、控制精确等优点，有很好的经济效益和广阔的发展前景。

Abstract

With the development of modern science and technology,automation equipment has bee- n applied in all areas of our lives,however,the devices of traditional medical transfusion are more efficient.Therefore, we need to improve the automation level of medical equipment, to facilitate the work of nurses and provide guarantees that are reliable and security for partients. This article depends on the principle tihat is reliable,easy to operate, saving labor,reducing la- bor intensity and improving the accuracy of operation, formming a master-local area network used by single chip of Sunplus of SPCE061A , which achieve automatic monitoring and regu- lation to the liquid dropping speed and monitoring the remaining liquid constantly.The control system consists of liquid dropping speed detection tache, water dropping speed control tache, display devices, microcontroller systems, keyboard and alarm system. This hardware implem- entation include SPCE061A MCU , sensors, DC servo motors,keyboards, digital tubes and so on. Software program use C language and assembly language co-written.Through a combinat- ion of hardware and software,to achieve a better control of the control system requirements.T- his single chip control system has the merit of high degree of automation, low cost, small size, precise control and so on.The system has good economic and broad prospects for developme- nt.

Keywords:liquid dropping speed, sensor,DC servo motor, SPCE061A single chip
