Smart home is based on the residential platform, using integrated wiring technology, network communication technology, security technology, automatic control technology, audio and video technology to integrate the facilities related to home life, build an efficient management system for residential facilities and family schedule affairs, improve Home security, convenience, comfort, artistry, and the realization of an environmentally friendly and energy-saving living environment.
Smart home is the embodiment of IoT under the influence of the Internet. Smart home connects various devices in the home (such as audio and video equipment, lighting system, curtain control, air conditioning control, security system, digital cinema system, audio and video server, video cabinet system, network appliances, etc.) Home appliance control, lighting control, telephone remote control, indoor and outdoor remote control, anti-theft alarm, environmental monitoring, HVAC control, infrared forwarding and programmable timing control and other functions and means. Compared with ordinary homes, smart homes not only have traditional living functions, but also have construction, network communication, information appliances, and equipment automation, provide a full range of information interaction functions, and even save money for various energy costs.
The concept of smart home originated very early, but no specific construction cases appeared until 1984, when United Technologies Building System applied the concept of building equipment informatization and integration to Hartford, Connecticut, USA. The first "smart building" appeared in the City Place Building, which opened the prelude to the world's scramble to build smart homes.
The most popular and essential part in the smart home is a smart switch. Compared with the mechanical wall switch, it has many features, is safe to use, and has a beautiful appearance. It breaks the single function of on and off of the traditional wall switch, in addition to the innovation in function, it also gives the switch the effect of decorative embellishment. Smart switches are widely used in smart home renovation, office smart renovation, industrial smart renovation, agriculture, forestry, fishery, animal husbandry and other fields, which greatly saves energy, improves generation efficiency and reduces operating costs. To achieve intelligent travel the world.
With the popularity of smart mobile terminals, the connotation of smart switches is also developing, and it has gradually become the preferred application for mobile phone control. On the basis of retaining remote control switches, it also expands energy consumption monitoring in smart homes and node strategy suggestions in the background of cloud services. Push and other complex scene value-added service models, smart switches are also going through the comprehensive energy deployment stage from a single individual, retail investors to intensive linkage of households.
The smart switch is evolved on the basis of the electronic wall switch. It is a subversive revolution to the original rocker-type mechanical switch. Since Edison invented the light bulb in 1879, there has been a simple mechanical switch. More than a hundred years have passed. There is no fundamental change in contemporary wall switches, there is no breakthrough development, and the mechanical switching method is still used. It was not until 1992 that electronic technology began to enter the field of wall switches. The development of electronic technology in wall switches has been in the early stage for more than ten years. The simple function stage wanders, and there are always only five types: touch delay switch, voice-activated delay switch, human body induction delay switch (PIR), knob dimming switch, knob speed adjustment switch.
With the development of science and technology, there has been a major breakthrough in the power supply technology of single live wire access for wall switches. At the same time, the introduction of microcomputer processing chips into electronic wall switches makes electronic wall switches with various functions feasible. In this technology, some companies have begun to launch a series of new electronic wall switches. At this time, the types of electronic wall switches have been greatly enriched and developed, so it is necessary to classify them. Nowadays, there are many differnt types of smart switch for different functions such as Zigbee Smart Switch, Smart Dimmer Switch, Smart Wall Switch, Smart Light Switch, Curtain Switch, etc.
