摘 要
本文主要是介绍了把无线传输技术和病护呼叫系统相结合应用的一个系统设计,整个系统是基于AT89C51单片机模块和无线射频模块相结合的一个无线多路病护呼叫系统。本设计是把无线传输应用到病护呼叫的课题,实现了基于AT89C51单片机的无线传输病护呼叫系统的模拟设计。本设计是以AT89C51单片机为核心控制,通过无线射频发射模块发射射频信号,无线接收模块接收到信号后把信息传输给单片机,单片机通过软件设计,对收到的信号进行多路判断,并对其他设备给出相应的指令信号,例如让蜂鸣器响起或者取消,让LCD显现出病护信息等。通过硬件和软件的调试设计,实现了病护呼叫系统的设计要求,并制作出模拟实物,检测基本正常,能够实现远距离接收信号。本设计的产品性能稳定,占用的空间也小,节省材料,信号传输速度快,是无线技术用于医学的创新应用,具有可行性。

ABSTRACT
This paper mainly introduces a system design which combines the wireless transmission technology and the nursing call system. The whole system is a wireless multi-path defense call system based on AT89C51 single chip microcomputer module and radio frequency module. This design is the application of wireless transmission to the call of the subject, to achieve based on AT89C51 single-chip wireless transmission of the call system simulation design. The design is based on AT89C51 microcontroller as the core control, through the radio frequency transmitter module to send RF signals, wireless receiver module to receive the signal after the information transmitted to the microcontroller, the microcontroller through the software design, the received signal to multiple judgments, and other The device gives the corresponding command signal, for example, let the buzzer sound or cancel, so that the LCD display shows the disease information. Through the design of hardware and software, the design requirements of the nursing call system are realized, and the simulation object is produced. The detection is basically normal and the remote receiving signal can be realized. The design of the product performance and stability, the space occupied by the night, saving materials, signal transmission speed, is the wireless technology for medical innovation applications, with the feasibility.
