Application of Wireless RF Technology Application in Smart Home

Radio frequency technology is a close distance, low complexity, low power consumption, low data rate, low cost wireless communication technology. The advantages of this technique are that some products do not need to rear line, and use the point-to-peer radio frequency technology to achieve control of home appliances and lighting. It is more convenient to install settings, mainly to implement control of certain electrical or lighting, moderate. Such system functions are relatively weak, and the control mode is relatively single, and it is susceptible to the interference and shielding of the surrounding wireless equipment, especially the same frequency and obstruction; more suitable for new loaded tricks and have been loaded. Be Smart home systems use computer, embedded systems, and communication network technology, with home as platforms, combined automation, information, intelligent, integrated, comfortable, safe, convenient, and environmentally friendly home living environment. At present, the intelligence of intelligent home life depends on the efficiency and reliability of information transmission, mainly wired transmission and wireless transmission. There is a shortcomings of wiring complicated, poor scalable, poor scarability, standard or unity, construction difficulties, and difficult market space. Wireless RF technology is a close distance, low complexity, low data rate, low cost wireless communication technology, due to its no need to rewir, use point-to-point radio frequency technology to achieve control of home appliance light and other equipment, and installation is convenient Simple control mode, in recent years, it has been widely used in smart home. Therefore, information transmission based on wireless radio frequency technology to achieve intelligent life is the focus of current smart home research, which will provide people with efficient, comfortable, safe and convenient living environment. Ordinary household or commercial receiver, usually using infrared (IF), signal transmission and reception requires a straight line path, which is easy to occlude the outer object. Using wireless RF technology, the signal transmission and reception is not blocked by the external object. Anyone in the system coverage, the system is in an open environment, the coverage can reach 100 meters. In addition, the wireless RF power consumption is low, and the coverage is widely regarded regardless of any orientation, and the reception is accurate and reliable. Taking a 200 square meters of houses as an example, the room is about 30 meters long, so the users can receive the remote control in any case where the coverage is covered. Each remote controller, switch or dimming switch is equipped with a wireless RF transmitter or receiver, so the remote control can directly send an instruction to each switch, control the preset lighting, without having to turn any wires.
