Design And Implementation Of Io T Intelligent Building Control System Based On Wifi

As an important embodiment of developing smart city,intelligent building has become a hot topic in today's society.In order to realize the intelligence of buildings and solve the problem of remote control of buildings,this thesis researches a intelligent building control system based on wifi,and introduces the design and implementation of the system.The intelligent building control system based on wifi realizes the wireless control and detection of intelligent terminal,which is divided into two parts: Arduino embedded device and upper computer control platform.Arduino embedded device consists of a Arduino UNO R3 development board,a ESP8266 wireless transmission module and sensor nodes.The Arduino UNO R3 development board is the main development board,which realizes the control and detection of the sensors through programming.The ESP8266 wireless transmission module is mainly responsible for the information interaction with the upper computer control platform,receiving control instructions or sending feedback information.The ESP8266 makes data interaction through serial ports with Arduino UNO R3 development board;The sensor nodes are used to simulate intelligent terminal in intelligent building,and feedback the environment data to the Arduino embedded device through sensors,realizing control and detection.The upper computer control platform adopts the B/S architecture and the MVC design pattern,including the front-end page,back-end service program and database.The front-end page is implemented through JSP technology,the back-end service program is developed using Java,the database chooses MySQL,and the control platform selects the integrated framework of Structs+Spring+Mybatis as a whole.Using the ESP8266 wireless transmission module to build a wireless LAN,the Socket communication algorithm can be realized through the back-end Java program,thereby realizing the wireless communication between the upper computer control platform and the Arduino embedded device.Experimental tests show that the Internet of things intelligent building control system based on wifi well realized the wireless control of the intelligent terminal and testing,with the characteristics of accurate control,accurate detection,reliable communication and low system delay,which basically meets the requirements of intelligent building.
