With the popularization of the concept of smart home , more and more smart home products have entered the homes of ordinary people. But what kinds of smart home technology are commonly used? I think many people are not clear, because the different technologies used in smart homes also cause the equipment between brands to be incompatible. After understanding the technology used in their smart homes, we are adding relevant smart homes later. When the product is in use, it will be more confident, and there will be no embarrassment that the purchased product cannot be used due to technical incompatibility. At present, the three mainstream technologies of smart home mainly include bus technology , wireless communication technology and power line carrier technology. The following is an introduction to you by the editor.
First, bus technology
The main feature of 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 capability, interoperability and interchangeability, and its control components are all Can be programmed. More influential bus technologies on 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. The advantages are mature technology, stable system, high reliability, and wide application. However, the general installation is more complicated and the cost is higher. The construction period is long, and it is only applicable to users who need to re-wire the newly renovated or retrofit old houses, and need professional maintenance for later.
Second, power line carrier technology
The power line carrier technology makes full use of the existing power grid, and the modem is used at both ends. The 50 Hz alternating current is used as the carrier, and the pulse of hundreds of KHz is used as the modulation signal to transmit and control the signal. Due to the high stability requirements of the power line carrier technology for the power grid, this technology is currently only used in a few areas such as remote power meter reading, building intercom, and lighting control.
