1 Introduction
In the information age, both mobile phones and home appliances are gradually integrated into the network. Information appliances are integrating modern network communication technologies into traditional household appliances, making them consumption of information access, acquisition, storage, processing, and networking. Electronic products. The emergence of information appliances has changed the traditional way of controlling home appliances, not only to control them locally, but also to control home-connected home appliances through the Internet. Due to the popularity of mobile phones and PCs, the use of the existing Internet makes smart home possible.
2 overall design of smart home control system
The overall structural block diagram of the smart home system is shown in Figure 1. The system consists of two major parts: the PC-based home monitoring center and the remote control points of the smart home appliances and monitoring equipment from the control center. System; use mobile phone as remote controller and use the Internet as a bridge to realize remote remote control.
The system function realization is that the monitoring center PC collects various data in real time through the single-chip monitoring software. When an abnormal situation is found, the system sends information to the user through an alarm mode such as short message or image, and processes according to a preset emergency program, such as smoke, Gas detection is abnormal. The user can also remotely set the smart home appliance through the mobile phone or computer using an Internet browser to access the controller site, such as the air conditioner/electric water heater on/off and its temperature setting.
3 system hardware design
The hardware system includes a remote control part based on a smartphone and a home control center mainly based on a home PC.
3.1 remote control terminal
With the development of smart phones. Its function is rapidly enhanced. At the 2006 Science Fair, Nokia called its high-end mobile phone a "multimedia computer" and demonstrated its powerful features: video calling, mobile email, multiplayer online games, instant messaging, wireless payment and other value-added services, and stressed that mobile phones will Become the main tool for people to log on to the Internet to request information. Future smartphones will be more powerful, such as GPS, open source operating systems, TV authentication access, and home base stations. At present, 3G is accelerating the convergence between mobile networks and traditional Internet, so that mobile phones continue to develop toward PC.
The main control unit of the equipment is PLC and the HMI (Human Machine Interface) is 7" LCD colorful touch screen. The equipment has varieties of operating modes, and can automatically record and save working status.The complete set of equipment is easy to operate, reliable in working, complete in protection and high in automation.
It has the features of high reliability, high pulse symmetry, strong anti-interference ability, quick reaction, as well as the advantages of no heat-generating, constant current, energy-saving which is compared with the discharge with the electrical resistance.
