OFweek Smart Home Network News With the popularization of smart home concepts, more and more smart home products have entered the homes of ordinary people. But what are the commonly used smart home technologies? I think many people are not aware of the difference in the use of smart home technology, but also caused the equipment between the brands is not necessarily compatible, in understanding what kind of technology their own smart home, we later added relevant smart home When the product is ready to be more confident, there will be no defects that cannot be used due to incompatible technology. At present, the three main technologies of smart home are bus technology, wireless communication technology and power line carrier technology. Here's an introduction for you by the editor.
One, bus technology
The main characteristic of the bus technology is that all equipment communication and control are concentrated on one bus. It is a fully distributed intelligent control network technology. Its product modules have two-way communication capabilities, as well as interoperability and interchangeability, and its control components are Can be programmed. The influential bus technologies in the market include LonWorks, KNX, EIB, CAN, BACNet and others. Bus technology products are more suitable for large area control such as building intelligence and community intelligence. Their advantages lie in mature technology, stable system, high reliability, and wide range of applications. However, general installation and installation are complicated and the cost is high. The construction period is long, and it only applies to users who newly renovate or renovate old houses and need rewiring, and they need professional personnel for maintenance later.
Second, power line carrier technology
The power line carrier technology makes full use of the existing power grid, and is equipped with modems at both ends. It uses the 50 Hz alternating current as the carrier and uses hundreds of KHz pulses as the modulation signal for signal transmission and control. Because the power line carrier technology has high requirements on the stability of the power grid, this technology is currently only used in a few fields such as remote power meter reading, building intercom, and lighting control.
Third, wireless technology
At present, the most commonly used wireless technologies for smart homes are WiFi, Zigbee, 433MHz and infrared wireless technologies. Wireless technology, because it does not require wiring and convenient construction, it can realize the installation of smart homes without major changes to the existing lines of the home. At the same time, it is convenient for maintenance and expansion at the later stage, and is increasingly sought after by smart home manufacturers and users.
