Smart Home

     Smart Home is a residential platform, the use of integrated wiring technology, network communications technology, security technology, automatic control technology, audio and video technology will be home-related facilities integration, the construction of efficient residential facilities and family planning business management system, Home security, convenience, comfort, artistry, and to achieve environmental protection and energy saving living environment.

     The concept of smart home originated very early, but there have been no specific architectural cases, until 1984, United Technologies Building System will be building equipment information, integration concept applied to Connecticut, Hartford CityPlaceBuilding, only appeared in the first " Intelligent building ", which opened the world competing to build a smart home camp prelude.

一、Home Automation

     Home automation refers to the use of microelectronics technology to integrate or control the home of electrical and electronic products or systems, such as: lighting, coffee stove, computer equipment, security systems, heating and cooling systems, video and sound systems. Home automation system is mainly a Central Processor Unit, CPU received from the relevant electrical and electronic products (changes in external environmental factors, such as the sun rose or sunset caused by changes in light, etc.) after the message, and then sent to the established procedures Appropriate information to other electrical and electronic products. Central microprocessors must be through a number of interfaces to control the electrical products at home, these interfaces can be a keyboard, it can be a touch screen, buttons, computers, telephones, remote control, etc .; consumers can send signals to the central micro-processing Machine, or receive signals from the central microprocessor.

     Home automation is an important system of smart home, when the smart home just appeared, home automation is even equivalent to smart home, today it is still one of the core of smart home, but with the network technology has a universal application of intelligent home network Home appliances / information appliances mature, home automation, many product features will be integrated into these new products, so that simple home automation products in the system design less and less, its core position will also be home network / home information system instead. It will play a role in the smart home as part of the control network in the home network.

二、Home networking

     First of all, we should put this home network and pure "home LAN" separately, we will also refer to this book "home LAN / home network" name, it refers to the family connected to the PC, all kinds of Set up a network system that is interconnected with the Internet. It is only an integral part of the home network. The home network is a new technology that connects PC, 

home appliances, security systems, lighting systems and wide area networks within the home range (scalable to neighbors). The current connection technology used in the home network can be divided into "wired" and "wireless" two categories. Cable solutions include: twisted pair or coaxial cable connection, telephone line connection, power line connection, etc .; wireless solutions include: infrared connection, radio connection, RF-based connection and PC-based wireless connection.

     Home network compared to the traditional office network, adding a lot of home applications and systems, such as home appliances, lighting systems, so the corresponding technical standards are also complex, which also involves too many well-known network manufacturers and home appliance manufacturers interests , We will be in the smart home technology chapter will be a variety of technical standards for a detailed introduction. The development trend of the home network is to integrate other systems in the smart home, and ultimately dominate the world.

三、Network appliances

     Network appliances is the use of ordinary household appliances digital technology, network technology and intelligent control technology designed to improve the new home appliances. Network appliances can be interconnected to form a home network, while the home network can be connected with the external Internet. It can be seen that the network appliance technology includes two levels: the first is the interconnection between home appliances, that is, so that different appliances can identify each other, work together. The second level is to solve the home appliance network and external network communication, so that the home appliance network truly become an extension of the external network.

     To achieve the interconnection between home appliances and information exchange, you need to address: 1. Describe the work characteristics of home appliances product model, making the exchange of data has a specific meaning; 2. Information transmission network media. Among the difficulties in solving the network media, the options are: power lines, radio frequency, twisted pair, coaxial cable, infrared, fiber. That the more feasible network appliances, including Internet refrigerators, network air conditioning, network washing machines, network water heaters, network microwave ovens, Internet cookers and so on. The future direction of network appliances is also fully integrated into the home network.

四、Information appliances

     From the general classification of information, information appliances actually contains the network of home appliances, but if defined from the narrow definition, we can do a simple classification: information appliances more with embedded processors with small home (Personal use) information equipment, its basic characteristics is connected with the network (mainly refers to the Internet) and some specific functions, can be a complete set of products, it can be an auxiliary accessories. The network of home appliances refers to a network operation with the function of home appliances products, this home appliance can be understood that our original ordinary home appliances upgrade.

     Information appliances consist of embedded processors, related support hardware (such as display cards, storage media, IC card or credit card read devices), embedded operating system and application layer software package. Information appliances to PC some of the functions of decomposition, designed to be more applied, more home appliances, so that ordinary residents step into the information age of the pace of more rapid, with high performance, low price, easy to operate the characteristics of the Internet tool. The emergence of information appliances will promote the rise of the home network market, while the development of home network market, in turn, to promote the popularity of information appliances and deep application.
