基于STC89C52的无线智能呼救系统设计

Design of the Wireless Intelligent Emergency Call System Based on STC89C52

针对医院病房中现有呼救系统不易维修、不易扩建、不易移动、病患需求未分类、病患需求未排序的问题,以STC89C52单片机为核心,采用nRF24L01(最高传输速率可达2 Mbps)进行数据无线传输,设计了一款低功耗智能分类排序的无线呼救系统。该系统能够快速准确地将病患需求传至护士站,并对病患需求进行分类排序显示,提高医护人员工作效率和准确性,为病患享受优质的医疗服务提供技术保障。

A low-powered intelligent classification wireless emergency call system is designed based on the core single-chip STC89C52 and nRF24L01(which could reach a highest transmission rate of 2Mbps)for wireless information transmission,aiming to solve the problems of difficult maintenance,extension,movement,classification of patients′needs with the existing distress call system in the hospital wards.This system can quickly and accurately transmit the needs of patients to the nurse station,sort out and display the needs of patients to improve the efficiency and accuracy of medical staff′s work,and to provide technical support for patients to enjoy quality medical services.
