(1)Now, we take a look at the smart home in the future life.Smart Home, also known as intelligent homes, is based on the future houses, which contain network communication, appliances control, automation equipment.Smart home system, using advanced computer technology, integrated wiring technology and various of subsystems aociated with home life make home life more energy-efficient, safe and comfortable.(2)In the smart home system, control center is the intelligent gateway, which is directly connected to the communication between users and appliances.Users can use mobile phones, computers and other appliances to achieve video surveillance, lighting, curtains and other controlling through the gateway.Similarly appliances give real-time feedback to the users through the gateway.(3) Let\'s look at the composition of the system.Smart Home system consists of three parts, intelligent appliances, intelligent control center and users, and control center is the core.They communicate with each other by Bluetooth and GPRS wirele network.As shown (4), we use controller STM32 as control center, the users contain cellphone APP, computer software.They communicate with each other by the Internet, wirele network, or Bluetooth network.So you can control the entire system via phone or computer at any time and any place.(5) This is the overall structure of the system, management computer, user, and cellphone users all belong to the user part.They communicate with the intelligent control center through the Internet, telephone network, and GPRS network, and the Bluetooth wirele network connects the control center with intelligent appliances and automatic security alarm respectively, thus the whole system is connected together. (6) Now I will introduce the software design of the system.Software design uses multithreading technology, and the design mainly aims at GPRS network.Household equipment and security system are monitored by mobile phone meages.This is the overall system software flowchart, the left part of the flowchart is software design of appliances controlling, which includes remote control thread, receive information thread, acce control thread, and state information, the right section is the software design of security system, including smoke alarm and broke alarm.(7) Finally I will introduce a specific software control, the control of intelligent appliances.If you want to control home appliances, open you cellphone and create remote control, the system receives control command by reading the serial data then the controller send a control signal, the control signal is amplified to drive a relay to control the state of appliance.As feedback, the state collector sends state information to users.
