智能家居的早期技术包括三大主流：①总线技术类：总线技术的主要特点是将所

Early smart home technology include three main: <br>① bus technology categories: the main features of bus technology is the communication and control all devices are concentrated on one bus, the product module has the ability to bi-directional communication, as well as interoperability and mutual change of which control means can be programmed bus technology products. But he's generally a bit more complicated installation settings, long duration, the cost is higher for newly installed user. <br>② wireless telecommunication technology: wireless communication technology there are many major programs successfully applied in the field of intelligent home wireless communication technologies are: radio frequency technology, VESP agreement, IrDA infrared technology, HomeRF protocol, Zigbee standard, Z-Wave standard, Z- world standard, X2D technology. The main advantage of wireless technology solutions, smart and easy to install, without re-wiring, you can always expand and modified according to the needs for newly renovated users and users has been installed.

Early technologies for smart homes include three majors:<br>(1) Bus technology class: bus technology is mainly characterized by all the communication and control of all devices are concentrated in a bus, the product module has the ability of two-way communication, as well as interoperability and interchangeability, its control components can be programmed bus technology products. But his general setup installation is a bit complicated, long duration, the cost is also high, suitable for new users.<br>(2) Wireless communication technology category: wireless communication technology has a lot of successful application in the field of smart home wireless communication technology, the main programs are: RF technology, VESP protocol, IrDA infrared technology, HomeRF protocol, Zigbee standard, Z-Wave standard, Z-world standard, X2D technology. The main advantages of wireless technology solutions, installation dexterity and convenient, no need to rewire, can be based on the need for any time to expand and modify, suitable for newly renovated users and installed users.

The early technology of smart home includes three main trends:<br>① Bus technology: the main feature of bus technology is to concentrate the communication and control of all devices on one bus. The product module has the ability of two-way communication, interoperability and interchangeability. Its control components can program bus technology products. But his general installation is a little complex, with a long construction period and a high cost, which is suitable for new users.<br>② Wireless communication technology: there are many kinds of wireless communication technologies. The main schemes of wireless communication technologies successfully applied in the field of smart home are: RF technology, Vesp protocol, IrDA infrared technology, HomeRF protocol, ZigBee standard, Z-Wave standard, z-world standard, x2d technology, etc. The main advantages of wireless technology scheme are smart and convenient installation, no need to rewire, and can be expanded and modified at any time according to the demand, which is suitable for new decoration users and installed users.
