摘　　要：病房呼叫系统是快速处理病人请求的重要装置,传统的病房呼叫系统缺乏根据病情对病房优先选择的能力,功能单一。本文基于单片机AT89C52设计具有优先选择功能的病房呼叫系统,采用独立按键输入病房号,利用单片机编程处理数据,当有多间病房同时呼叫时对应指示灯同时亮,但在数码管上只显示优先级别高的病房号,并伴有报警提示铃响。The ward call system is an important device for the rapid processing of patient requests The traditional ward call system lacks the ability to prioritize the wards according to the illness, and the function is single This article is based on single chip microcomputer AT89C52 design which has the function of priority ward calling system, adopt independent key input unit, microcontroller programming processing data, when there is more room call at the same time corresponding indicator light at the same time, but only on the digital tube display high priority ward, and accompanied by alarm prompt the bell rang.
