摘   要
 红外数据传输是目前使用最广泛的一种通信手段,由于红外线装置具有体积小、功耗低、功能强、成本低等一系列优点,因而在彩电、音响设备、空调以及玩具等其它无线遥控电器设备上也纷纷采用红外系统,用来实现数据的传输。在工业领域,使用红外设备来传输很广泛,采用红外数据传输不仅安全可靠而且没有电气干扰。
 本次毕业设计的题目是基于语音播报的病床呼叫系统,主要由AT89S52单片机控制模块、按键输入、LED数码管显示、红外发射模块、红外接收、ISD语音播报等模块组成,通过单片机进行编程控制以及红外发射端和接收端相结合,主要功能是实现病床对总站的呼叫,在系统前端采用红外线无线传输,在接收端对呼叫病床号的显示和语音播报。
    本系统可以及时的让医护人员了解病人需要,由于在前端采用红外线遥控,能更加方便病人对医护人员的呼叫。此外,本系统还具有价格便宜,操作简单,具有广泛的应用前景。
关键词:红外线传输、ISD语音播报、LED数码管显示
Abstract
 IR data transfer is used widely in data communication. Infrared devices have got a series of advantages such as small size, low power consume, functionality and cheapness and so on. It is widespread used in the colorful TV, audio equipments, air-conditioners and other wireless remote control toys. The using of infrared systems is also used to transfer data. In the industrial field, the use of infrared equipments to transmit a wide range, using infrared data transmission is not only safe and reliable, but also has got lower electrical interference.     The subject of the infrared calling system based on broadcast, it mainly consists of the AT89S52 SCM control module, keyboard module, LED display module, the infrared transmitter module, infrared receiver module, voice broadcast module and so on. By the SCM programmed controlling, main function of the system is to achieve infrared data from the transmitter to the receiver, the main function is to achieve the hospital's call to the terminus in front-end system using infra-red wireless transfer, the receiving end in the number of hospital beds to call display and voice broadcast .
 The system can prompt the patient to allow medical staff to understand the needs of front-end due to the use of infra-red remote control, more convenient to call the nurses. In addition, the system is cheap, simp, simplictly of operator and wide application.
