The early origins of the smart home concept, but there has been no specific case of building appear,until 1984 the United Technology, Inc. (United Technologies Building System) construction equipment. information technology integration concept used in the U.S. state of Connecticut (Conneticut) Hartford (Hartford) City Place Building Home Building "intelligent building" , from that time , also opened the compete prelude to build the smart home all over the world.

After many years of accumulated demand, At present ,usually smart home is defined as the use of computers, networks and integrated wiring technology, Through the family information management platform will be related with the household life of the various subsystems organically combined into a system.Specifically, it is the first in a household set up a communication network to provide the necessary path information for home, under the control of the operating system in the home network, through the corresponding hardware and actuator, implementation of all household electrical appliances and devices on the network control and monitoring. Secondly,they must  through a certain network platform, constitute a channel of communication with the outside world, in order to achieve the information communication with the world outside beyond the family, to meet the remote control, monitoring and exchange of information needs. Finall to satisfy people to safety, comfort, convenient and green environmental protection requirements

Along With the socio-economic structure、Family structure and development of information technology change, And the human for environment of safety, comfort, and Improvement of efficiency,cause the smart home demand increase greatly, at the same time, more and more families request smart home products not only to meet the basic needs, but also request the smart home systems function extension, the extension services to do simple, convenient and safe.

 II. Commonly used in smart home technology introduction and compare

    Although the concept of smart home is very early, the market demand has always existed, but the development of smart home for a long time due to subject to the relevant technical breakthrough, has not been large-scale popularization application,.At present the Smart home technology market as follows:
1 wired
   In this way, all of the control signal must be connected through a wired,and the controller end of the signal line is more scary, but once meet the trouble is quite difficult. The wired way drawback is very prominent ,complicated wiring, heavy workload, high cost, difficult to maintain, difficult to network. These shortcomings eventually led to the wired smart home keep the concept and pilot stages, can not be a large-scale promotion.
2 wirelessly
   For smart home wireless system needs to meet a few features: low power consumption, stable, easy to extend the grid; As for the transmission speed is obviously not the focus of such applications. At present, Several can be used in smart home wirelessly
   Bluetooth: is a kind of support device (Generally within 10m) short-distance communication radio technology. can be included mobile phone 、PDA, wireless headset, laptop computers, associated peripherals, and many other devices between wireless information exchange. But this technology communication distance is too short, at the same time is a peer-to-peer communications, for requirements of smart home does not apply.
    WIFI: Actually is the nickname of IEEE 802.11 b ,Is called a” compatible Wireless Ethernet Alliance” (Wireless Ethernet Compatibility Alliance, WECA) released by the organization of industry terminology, Chinese translation for "wireless compatible authentication". It is a short-range wireless transmission technology, support for Internet radio signals in the range of a few hundred meters. It's the biggest feature is convenient for people to access the Internet anytime, But the disadvantage is obviously for smart home applications, High power consumption、professional networking. High power consumption for the deployment of low-power sensor anytime is very fatal flaw, So the wifi although is very popular, But in the application of smart home  just played a subsidiary role

    315M/433M/868M/915M: The radio frequency (RF) technology is widely used in vehicle monitoring, remote control, telemetry, small wireless network, industrial data acquisition systems, wireless tags,ID identification, non-contact RF and other places, and also has the manufacturers to introduce to smart home system, but due to the weak nti-interference ability, networking inconvenience, general reliability, in smart home is far from satisfactory for people, eventually abandoned by mainstream manufacturers.
Zigbee: Zigbee is based on IEEE 802.15, but IEEE just only deal with low-level MAC layer and physical layer protocol, So the Zigbee alliance expands the IEEE ,and for the network layer protocol and API standardization.Zigbee is a new emerging short-range, low-rate, low-power wireless network technology, mainly used for short-range wireless connection. With low complexity, low-power, low-rate, low-cost, Ad-hoc network, highly reliable and BVR characteristics. mainly suitable for application in areas such as automatic control and remote control, Can be embedded into a variety of devices. In a nutshell ,ZigBee is a cheap 、Low power consumption、ad hoc network of short-range wireless communications technology.
III. Under the background of the Internet of things smart home understand

ZigBee initially expected application areas, including consumer electronics, energy management, health care, home automation, building automation and industrial automation. With the rise of the Internet of things, ZigBee has got a new application opportunities again,Internet of things applications is sensor network edge or control unit,

in thousands of tiny sensor and ZigBee can drive the mutual coordination and communication between units,and the unit only needs very little energy, By way of relay the data by radio waves from one network node to another node, so it's very high communication efficiency. This technology is a low-power,anti-interference, high reliability, easy networking, easy expansion, easy to use, easy to maintain,to facilitate rapid large-scale deployment characteristics conform to the requirements of the development of the Internet of Things and trends. From the Current point to view, the Internet and ZigBee technology in the smart home, industrial monitoring and health care application has a lot of fusion etc.

It is worth to note that the rise of the Internet of the things bring a broad market space for ZigBee. For the purpose of the Internet of things is to combine all kinds of information sensing transmission unit and the Internet to form a huge network, in the vast network, sensing transmission unit and the need for data transfer between communication network, and relative to other wireless technology, ZigBee is known for its advantages in investment, construction, maintenance, etc, will be in the Internet of things smart home gain wider application.

IV. Plan selection

As a standard smart home, need to cover a wide range of applications, but the precondition is must any ordinary consumers can be very simple and quick to install their own deployment even Even extending application, without the need  professional installers on-site installation.
