摘要病房呼叫系统，顾名思义，就是用在病房里充当呼叫功能的设计，想一下，假如一个老人生病住院，家里人又都是很忙，没人陪同，如果医院里么有呼叫系统，老人需要医生时自己行动不便又没人可以帮助，一旦遇到问题后果不堪设想，如果有了这个呼叫系统，直接通过按下按钮就可以通知医护人员，这样避免了医疗事故的发生。病房呼叫系统直接关系到病人的安全能否得到及时的救济，一直是各大医院的深切关注。有利于促进及时，准确可靠，简单可行的病人呼叫的表达。26188
本设计以51单片机为核心设计的病房无线呼叫系统，是单片机领域理论到实践的一次大胆的尝试，分析了硬件电路与软件设计。本文对主机通过nRF24L01无线传输模块由机床发送实时采集床，主机接收从上位机发送信号，报警，控制蜂鸣器和LED提醒病人呼叫，护士主机回声按键，取消相应的调用。数据传输距离的实现。本系统从机检测和主机显示报警部分接收的回波。本产品性能稳定，占用空间小，耗费材料少，传输速率较快，传输距离远，是单片机无线技术在临床医学管理中的一个大胆的应用，相比较以前的设备，具有很大的创新性，和可行性。

Ward call system, as the name suggests, is to use in the ward as calling function design,  think about, if an old man is ill in hospital, family are very busy, not accompanied, if the hospital? Call system, the elderly need doctor his action inconvenience and no one can help, once encounter problems will lead to disastrous consequences, if the call system, directly with the press of a button you can notify the medical staff, this game, avoid the occurrence of medical accidents. Ward call system is directly related to the safety of patients can get timely relief, has been deeply concerned abouthospitals. To promote timely, accurate and reliable, simple and feasible patient callexpression,.
This design is based on 51 single chip computer as core design of ward wireless call system, is the field of SCM theory to practice a bold attempt, analyzes the hardware circuit and software design. This paper on the host through nRF24L01 wireless transmission module by the machine to send real-time acquisition bed, the host receives from PC to send signal, alarm, control buzzer and led to remind a patient calls, nurse host echo button to cancel corresponding to call. The realization of data transmission distance. This system from  machine to detect and display the alarm portion of the received echo. The product performance is stable, little space occupation, little material consumption, transmission speed faster, transmission distance is far, wireless SCM technology in clinical medicine management in a bold application, compared to the previous equipment, with great creativity, and feasibility.
