| With the rapid development of economy,people have higher and higher requirements for home life,which brings opportunities to the development of smart home.Smart home meets the needs of people and realizes the intelligence of household appliances and other equipment,so as to get rid of the traditional working mode of household appliances.When people go out,as long as security surveillance is installed at home,they can observe the situation through mobile phones anytime,anywhere.Not only that,but also through the network intelligent control of household appliances switch,people on the way home,can turn on the control,open the electric rice cooker to cook.When you get home,you can enjoy dinner immediately,which gives you a very comfortable living environment.These are the changes that smart homes have brought to our lives.In the past,there were some smart homes,but the former smart homes were arranged through the network line,and the control was more scattered,and the wiring was more tedious.If WiFi communication technology is used to connect home devices together and connect to Ethernet,remote control of smart homes can be realized.And WiFi technology is connected wirelessly,saving the manpower,material and financial resources of wiring.It perfectly solves the bottleneck problem of traditional smart home.Based on the analysis of the current development situation of smart home control system at home and abroad,this paper designs a control system based on WiFi smart home gateway to solve the problems of high cost and high complexity in smart home control system.The gateway solves the shortcomings of traditional smart home control system,such as poor mobility,complex system,high cost and so on.It combines WiFi technology,ZigBee networking technology and Ethernet communication technology,which makes the smart home system gateway have flexible and changeable control mode.People can use smart phones,PCs,tablets and other devices to control smart homes.As long as the communication equipment connected to the Internet can control the household appliances by sending instructions,or monitor the status of household appliances,so as to improve people’s living environment and quality of life.In order for household appliances to be connected to Ethernet,it is necessary to have wireless WiFi function in order for household appliances to be connected to smart phones.In this system,we pay attention to the performance test of WiFi,the debugging and matching technology of wireless antenna,the matters needing attention in circuit design,PCB layout power supply design,signal integrity design,RF network wiring design and so on. |
