The Design And Implementation Of Smart Plug Based On WiFi

Since the 1980 s,household appliances began to use electronic technology and put on sale,with the help of electronic technology,Home Electronics appeared in the mid-80 s,which is made up of the home appliances,communications equipment and security equipment.In the next period of time,because of the installation of trouble,the use of complex,unfriendly interface,high cost,smart home market is in a dormant period.With the technology maturity of electronic science and the system of hardware and software costs down,and a higher life Quality requirements,smart home industry was in the rapid expansion,occupation of the market.The smart socket which is based on cloud platform is mainly composed of three parts: the hardware device,the cloud platform and the terminal customer.The hardware device is the function carrier of smart plug.Cloud platform is to play the information interoperability and the client's leading function.To ensure control legitimacy,system adds the function of control authentication,this function can make the link transmission safety and cannot subject to environmental pollution and interference thus ensure the safety of link data,abandon the way of the clear text transmission and use ciphertext to transmission context,increased the difficulty of breaking the data to ensure that user's privacy.This article will work from the above three parts to build a WiFi-based intelligent smart plug system and control socket in near-field or remote-field.Based on this,this paper has done a lot of work,1.the research of the advantages and disadvantages of WiFi module,and the selection of hardware design,and completion of the smart socket hardware products according to this program between the circuit board and embedded software areas;2.based on the Apache Mina framework,design the hardware communication protocol among the hardware side,the server side and the terminal.The communication information between the terminal and the server is stored in JSON format.The communication among the three roles uses the RSA encryption algorithm and finally realizes the real-time Remote control,user information operation,log information preservation.Designing mobile app is used to control the smart socket directly in the LAN and in the WAN through the server.
