基于单片机的多机通信系统设计

Design of multi computer communication systembased on single chip microcomputer

随着现代科技的进步与科技能力的发展,对控制技术的要求越来越高,如无接触控制、远距离通信已经在现代的科技产业发挥重要作用.人们对通信质量的要求也越来越高,因此以单片机为基础的远距离通信的科技研究意义也愈发重要.多机通信系统由AT89C51单片机模块、HC-05蓝牙模块、LCD1602液晶显示模块、按键、发光二极管、蜂鸣器等部分构成.当给2个电路模块上电以后,2个电路通过蓝牙进行连接,按键触发指令可以改变单片机寄存器内储存数据值,2个显示模块电路可以相互传输与接收数据,该功能可应用于医院日常排号叫号的过程,也可以设计成无线叫号系统.

With the progress of modern science and technology and the development of scientific and technological ability,the requirements for control technology are higher and higher.For example,contactless control and long-distance communication have played an important role in modern science and technology industry,and people’s requirements for communication quality are higher and higher.Therefore,the scientific and technological research significance of long-distance communication based on single-chip microcomputer is becoming more and more important.The multi-computer communication system is composed of AT89C51 single chip microcomputer module,hc-05 Bluetooth module,LCD1602 LCD module,key,led,buzzer and other parts.When the two circuit modules are powered on,the two circuits are connected through Bluetooth.The key trigger instruction can change the data value stored in the single-chip register,and the two display module circuits can transmit and receive data from each other.This function can be applied to the process of daily number arrangement and calling in the hospital,and can also be designed as a wireless calling system.
