摘要
本设计是以AT89C51单片机为基础,并且结合无线收发模块以及发光二极管、蜂鸣器等进行设计的。在经过反复思考和查阅大量资料后,最终决定该设计的无线模块采用n RF24L01新型单片射频收发器件。医院无线呼叫系统的主要作用是:当病人发生紧急情况时病人可以按下呼叫按钮,医生就会及时赶到病房对病人进行救治。通过研究可以发现该系统使用方便、快捷并且具有较高的稳定性。
The design is based on AT89C51 MCU, which contains wireless receiving-and-sending module, lightemitting diodes and a buzzer. I finally decided to use nRF24L01, the new type of monolithic RF transceiver components, for the wireless module after repeated thinking and amounts of reading. The main function of hospital＇ s wireless calling system is that： when the emergency appears, the patients can call the doctors immediately and doctors can also arrive at once. The system is easy-using, fast and high stability.
