As we all know, the most important thing for smart home is to realize the interconnection between smart products. How to realize the communication between smart home products, how to ensure the execution of products when shouting orders?
All this must involve the communication architecture. The current smart home communication network architecture includes three major categories.
Smart home communication network architecture three major types of technology
The realization of smart home control belongs to information network and control network technology. There are three main types: bus technology, wireless technology, and power carrier technology.
Bus technology is the connection of components to a component of a computer processor that enables the transfer, exchange, sharing, and logic control of information between components within the entire system. It is divided into external and internal buses, system buses and non-system buses.
Wireless technologies are also divided into different types, usually in the form of wireless signals. Currently, the main methods are FM wireless technology, infrared wireless technology and Bluetooth wireless technology, and their cost and characteristics are not the same.
Power carrier-based communication (PLC-Power-line-CommunicaTIon) is a unique communication method for power systems. Power carrier communication refers to a technology that uses an existing power line to transmit analog or digital signals at high speed through a carrier. The biggest feature is that there is no need to re-arrange the network, as long as there is a wire, data can be transferred.
First, the application of bus technology in smart home
The application of bus technology in smart home lies in the home bus system. The home bus is an important foundation for the realization of smart home. It is the inner nervous system of the house. Its main function is to connect various electronic and electrical devices in the home. It is responsible for all kinds of communication devices in the home (including security, telephone, home appliances, audio-visual equipment). Etc.) Connect together to form a complete home network.
Japan proposed the concept of the Home Bus System (HBS) earlier, established the HBS Research Association, and formulated the HBS standard in Japan, and later developed into the S-HBS system, which is the Super Home Bus.
Second, the application of wireless technology in smart home
For the moment, wireless smart homes are mainly divided into Bluetooth, Wi-Fi, Zwave and ZigBee according to the technology used. Wireless technology enables people to remotely control the home. Below we may wish to start with the most frequently used WiFi.
