毕 业 论 文 论文题目 医院病房紧急呼叫系统 1 基于 51 单片机的医院病房紧急呼叫系统 摘要 本文介绍了一种以 AT89S52 单片机设计的医院病房无线呼叫系统。该系统由 单片机系统、无线收发系统、功能开关、 1602 液晶显示器、以 ISD4004 语音芯片 为主的语音系统等单元电路组成。该系统所用到的无线收发系统采用 315 无线收 发模块的 PT2262和 PT2267 编解码芯片,利用单片机的串行半双工通信来实现。 它的核心控制器采用价格低廉,性能可靠的单片机。该系统主要工作原理是分机 按键呼叫,主机声光报警,同时显示呼叫的号码,主机按键可回复。研究表明该 系统使用方便、快捷、安全可靠,可应用于医院、茶庄、 KTV、餐厅等领域。在市 场经济体制中,尤其在服务性的行业中,更省人、省钱、省心,更能提高企业效 率,提高服务形象,带来更好的经济效益,可作为电子产品进行开发研制,具有 很好的推广价值。 关键词: 单片机技术 无线发射和接收 无线呼叫系统 ISD4004 1602 2 The Urgent Calling System In Hospital Words Abstract This paper introduces a SCM(single-chip microcomputer) ATMEL AT89S52 MCU as a wireless calling system in hospital wards. This system consists of SCM system, wireless transceiver system, the functional switch, 1602 LCD, and by the main of voic ISD4004 as a voice systems unit circuit etc. What the use of the system is the wireless transceiver system which invlves a wireless transceiver module 315 of the PT2262 and PT2267 codec chip, and brings about the SCM -duplex communication. The core’s half controller optionaled SCM with low price and reliable performance. The call ext press then the host sound-light alarm, display the call numbers at the same time and at last the host give a reply by press the button is the main working principle of the system. The study shows that this system has the characteristics of easy to sue, fast, safe and reliable. And it can be used some social fields such as hospital, tea house, KTV, restaurant, etc. In the market economic system, especially in the service industry, Using
