基于单片机的病房呼叫系统设计

摘要

医疗呼叫系统是提高医院医疗服务水平和质量的一个重要组成部分，医院医务人员与病人之间信息沟通是医疗呼叫系统的主要功能。无线医疗呼叫系统可在不改变病房现有布局的情况下实现医务人员与病人之间的交流。

本文介绍了一种基于STC89C51单片机的病房呼叫系统，整个系统以STC89C51单片机为核心辅以无线模块以及显示电路，能够实现病人和医护人员之间的信息传递。当有按键按下时，无线发射模块编码并发射信号，再由无线接收模块接收到信号译码后汇总到单片机，最终由LCD1602示出呼叫者的病床号并伴有蜂鸣器的报警声，从而获得医疗救治。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。

THE DESIGN OF SICKBED CALLING SYSTEM BASED ON SINGLE CHIP MICORCOMPUTE

Abstract

Medical Call system is used to improve the health care in hospital and its main function is to keep in touch between the doctors or the nurses and the patients. They can contact with each other by the wireless medical call system(WMCS) under unchanging existing ward's layout.

This paper introduces a kind of Sickbed Calling System based on STC89C51 Single Chip Microcomputer. All the system as STC89C51 Single Chip Microcomputer as core, and coupled with wireless module and display circuit, so it let the exchange between doctors and patients comes true. This project use the button replace the button beside sickbed. When someone press down the button beside the sickbed to need doctors or nurses help.Through the wireless send module to send the message, then received by wireless receive module and collected by Single Chip Microcomputer, displayed by LCD1602 indicator and accompany with alarming from buzzer at last, so that they receive the help from doctors or nurses. This equipment provide a low cost and efficient and easy to manipulate system to the hospital.
