基于单片机的病床呼叫系统的设计 摘 要 病房呼叫系统是病人请求值班医生或护士进行诊断、护理的紧急呼叫工具，它主要用于协助医院病员在病床上方便地呼叫医务人员，可将病人的请求快速传送给值班医生或护士，是提高医院和病房护理水平的必备设备之一。医院的竞争越来越激烈，商业医院的生存是第一位的，提升档次和服务质量迫在眉睫，陪护问题一直是医患矛盾的主体，也是长期困扰卫生系统服务质量的大问题，使用病房呼叫系统，方便病人更快找到医生，以节约病人的宝贵时间 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。每个病人要呼叫可以按键，同时会有蜂鸣器响，不同的数码管显示床位号，相应的指示灯亮。这里主要矩阵键盘输入信号，这是编程的关键。 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：AT89C51，矩阵键盘，LED，病床呼叫 DESIGN OF WARDS CALL SYSTEM BASED ON MICROCONTROLLER ABSTRACT Ward?call system?is the?patient's request to?the doctor on duty?or nurse?emergency call?tools?for?diagnosis,?care,?and?it is mainly used?to?assist?the?hospital?patient?in?the bed?easily?call?the?medical staff,?the patient's?request?can be?quickly sent?to the?duty doctor or nurse?is to improve one?of?the?essential?equipment?of?hospital?and ward level of care.Increasingly fierce?competition?in?the?hospital,?commercial?hospital survival?is the first to enhance the?grade?and?quality of service?is?imminent,accompany the?issue has been?the main body?of?the?patient conflict, but also?long-troubled?health system?quality of service?issues,?using?the?ward?call system?more convenient for patients?to find a doctor?to save?the?valuable time?of?the?patient.
