单片机单片机结课设计病房呼叫系统设计学生姓名院系信息技术学院专业学号 2013 年 12月单片机摘要系统是基于 51 系列的单片机设计的病床呼叫系统。该系统以 AT89C51 单片机为核心辅以矩阵键盘、LED 点阵显示电路和部分简单模拟和数字电路组成的能够实现病人和医护人员之间信息的传递。在该设计中每个病房都有一个按键,当患者有需要时,按下按键,此时值班室的显示屏可显示此患者的床位号,多人使用时可实现循环显示,医护人员按下“响应”键取消当前呼叫。此系统能够为医院提供一个成本低、效率高、操作方便和易于安装维护的快捷系统。关键词:单片机;LED 显示;呼叫系统 Summary System isbased on51Series MCU design beds calling System. This system with AT89C51 microcontroller core supported byamatrix keyboard, LED dot matrix display circuit and some simple analog and digital circuits toachieve the information transmission between patients and medical workers. Inthe design ofevery Ward has akey, when need arises, press the button, atthis time the guards 'room screen can display the patient's bed, many people can achieve when using the loop displays, medical staff bypressing the ""key tocancel the current call. This system can provide alow cost, high efficiency, ease of operation and ease ofinstallation and maintenance and efficient system.
