智能家居系统——网络结构搭建与算法研究

Intelligent home system design--network structure construction and researchAbstractUnder the tide of global intelligent development,the quality of life pursued bypeople is getting higher and higher,and more and more smart homes are graduallyentering people's life.Smart home system including computer technology,networkcommunication technology,intelligent control,Comprehensive wiring technology.Smart home is according to the principle of human engineering which is integration ofconsumer demand.It makes the daily household system related together organically.Such as security defense system,temperature control system,humidity control system,lighting control system,gas detection system.Realize intelligent control andintelligent management through wireless communication,so that people can feel themost comfortable and convenient new home life experience.This graduation project mainly aims at the construction and research of thenetwork structure in the intelligent home system.The system is mainly composed oftwo parts:the hardware system and the software system.About the hardware system,the STM32 MCU is the principal computer,and the AT89C52 MCU is the slavecomputer.The ESP8266 wireless module is a tool which make them connectionestablishment.In addition,the hardware system is also include the temperature testmodule,humidity test module,AD/DA converter module and so on.About thesoftware system,we use the serial port communication technology make the MCUand the ESP8266 establish communication.Using the Keil uVision4 and Keil MDK5Software development platform to write programs.In order to convey informationbetween principal computer and the slave computer.To be specific,using the WIFItechnology to realize the electronic data interchange between the STM32 MCU andthe STC52 MCU.After that,we can use the STM32 MCU to control all the parts ofthe STC52 MCU by using wireless communication technique and makes the smarthome system operation.This thesis not only describe about how to set up thewireless communication between principle computer and slave computer,and alsodescribe some arithmetic research for the programs.Key words:Smart home system;STM32;STC89C52RC MCU;WIFI;Serial portcommunication
