医院门诊排队叫号系统
摘要
排队叫号管理系统是针对银行、工商、税务、通讯、政府机构等部门的大厅工作流程设计的,是利用电脑的科学管理客户排队的系统,很好地解决了客户在服务机构办理业务时所遇到的各种排队、拥挤和混乱现象,为客户办理业务带来莫大的方便和愉悦。本课题研究的目的是研制一款无人排队的排队叫号机,它主要由主控制器、键盘、显示电路、蜂鸣器电路等部分构成。系统利用单片机进行控制,通过串行通信方式传输处理数据;通过按键取号,在LCD1602上显示排队的号码以及当前正在等待的人数;通过按键叫号,在LCD1602上显示叫到的号码,由扬声器发出声音提示客户。同时免除了令客户不舒服的站立式排队,这种现代化的高科技产品彻底解决了医院普遍存在的站立等候,服务无序的问题,深化并完善了服务的质量。本系统采用单片机进行控制,利用LCD1602显示,蜂鸣器鸣叫提示的人机交互界面,模拟排队管理系统,科学地处理各种排队情况。操作简便,控制灵活,显示清晰,制作成本低,性价比较高。

ABSTRACT
The queuing management system of the design is aimed at Banks, industry merce, taxation, communication, government institutions and other departments of the working process , Is using a scientific management system of customer queue ,is very good solution to the customers in the service agencies for business encounter all sorts of queuing crowded and chaotic phenomenon, for the customer has brought great convenience to transact business with pleasure. The purpose of this research is to develop a line of No queuing machine, and it mainly consists of the main controller, keyboard, display circuit, buzzer circuit part. System controlled by microcontroller, through munication mode processing data; through the key take number, LCD1602 lined up in display on the number and the number of waiting; through buttons, In LCD1602 display on the number, called by the speaker sound tip customers. Meanwhile from customers' fortable stand type, the modernization of queue high-tech products thoroughly solved the hospitals widespread stood waiting, service disorder and perfected the problem, deepen the quality of the service. The system adopts single-chip puter controlling, showing by LCD1602, man-machine interface of Buzzer chirping hinting, Simulating queue management system, Scientific dealing with various kinds of queuing. It has simple operation, control, display, making clear flexible low cost, high cost performance.
