Aubrey fabric curtain is the mainstream technology of QSA smart home.

The first category-bus technology category

The main feature of bus technology is that all devices communicate and control on one bus, which is a fully distributed intelligent control network technology. Its product module has two-way communication ability, interoperability and interchangeability, and its control elements are programmable.

The typical bus technology adopts twisted-pair bus structure, each network node can get power from the bus, and can also realize the interconnection and communication between nodes without polarity and topological logic through the same bus.

Bus technology products are more suitable for large-area control such as building intelligence and community intelligence, but generally the installation is more complicated, the cost is higher and the construction period is longer, which is only suitable for newly renovated users.

The second category-wireless communication technology.

There are many wireless communication technologies, and the wireless communication technologies that have been successfully applied in the field of smart home mainly include: radio frequency (RF) technology (frequency band is mostly 3 15).

And 433.92MHz), VESP protocol, IrDA infrared technology, HomeRF.

Zigbee protocol

Standard, z-wave

Standard, z world

Standard, X2D

Technology, etc.

The main advantages of the wireless technical scheme are convenient and flexible installation, no need to rewire, and it can be expanded or modified at any time as needed, which is suitable for newly renovated users and installed users.

The third category-power line carrier communication technology

Power line carrier communication technology makes full use of the existing power grid, and there are modems at both ends, directly at 50Hz.

Alternating current as a carrier, and then hundreds of KHz

Pulse is a modulated signal, which is used for signal transmission and control.
