摘要
为改善营业窗口的服务质量和工作效率,解决枯燥无序的排队问题,采用STC89C52单片机控制语音芯片、打印机、LCD显示屏来模拟人工叫号过程,完成号码的打印、存储、显示及播报工作;采用MAX485扩展RS-485总线接口,实现分布式串行通信。该系统能满足简单的排队需求,具有开发成本低,占用空间小等优点,有较好的市场应用前景。
In order to improve the Service quality and work efficiency,to solve the dry and disordered queue problem,the system simulated the artificial process of calling number,using STC89C52 MCU control printer,LCD and voice chip to achieve the work that print,storage,display and broadcast line number.Furthermore,using MAX485 to extend RS-485 bus interface,that can achieve distributed serial communication.The system can meet the needs of casual queue and has many characteristics,such as low cost,small space occupation and better prospect.
