基于MQTT协议的智能开关系统的设计

Design of Intelligent Switching System Based on MQTT Protocol

随着物联网的普及,每个人的家里或多或少都有智能家电,而且近年来市场规模和需求量在不断扩大。在这样的大趋势下,设计一套智能开关系统,意在帮助人们管理家中电器。智能开关系统由3个部分组成:硬件设备端、软件控制端、云服务器端。本设计可以检测当前环境数值(温度、湿度、光照强度),通过检测到的数值来控制相应的控制器进行开关操作,并且可以在OLED屏幕上看到环境信息。本设计具有快捷、方便等优点,能更加有效地控制开关。利用ESP8266 WiFi模块、消息队列遥测传输协议(即MQTT协议),结合目前流行的云服务器、Micropython编程语言、Tkinter桌面程序编程,通过系统测试完成了此智能开关系统的设计,实现了通过电脑端来远程控制开关。

With the popularity of the Internet of Things,everyone has smart appliances at home more or less,and the market scale and demand are expanding in recent years.Under such a general trend,a set of intelligent switching system is designed to help people manage home appliances.The intelligent switching system consists of three parts:hardware device end,software control end and cloud server end.The design can detect the current environmental values(temperature,humidity,light intensity),control the corresponding controller switch operation by the detected values,and can see the environmental information on the OLED screen.This design has the advantages of fast,convenient,and can control the switch more effectively.Using esp8266 WiFi module,Message Queuing Telemetry Transport protocol(MQTT protocol),combined with the current popular cloud server,Micropython programming language,Tkinter desktop program programming,the design of the intelligent switch system is completed through system testing,and the remote control switch is achieved through the computer.
