Haier smart home technology features
First, the technical characteristics of the smart home platform system
Smart home networks continue to evolve with the implementation of integration technologies, communication technologies, interoperability and cabling standards, involving the operation, management, and integration of all smart devices, devices, and systems within the home network.
(1) Establish a home intelligent platform system through the home gateway - home smart terminal and its system software.
Home network magnetic is the core part of the smart home LAN. It mainly completes the conversion and information sharing between different communication protocols in the home internal network, and the data exchange function with the external communication network. At the same time, the gateway is also responsible for the home smart device. Management and control.
Using computer technology, microelectronics technology, communication technology, home smart terminal (home gateway) to integrate almost all functions of home intelligence, so that smart home is built on a unified platform. First of all, the embarrassment between the home internal network and the external network is smooth and accurate. Secondly, it is necessary to ensure that the instructions that can pass through the network are legal and the illegal cloth is not a "hacker". Therefore, the home smart terminal is not only the transportation hub of family information, but also the protection god of the informationized family.
(2) Realizing interconnection with network home appliances through communication module
In order to realize the network function of household appliances, each home appliance must have a communication module. For different physical media, different communication modules are required, and the communication module is an interface for upgrading traditional home appliances to network home appliances. In order to ensure proper communication between appliances and between home appliances networks and gateways, a complete communication protocol must be developed.
(3) Application of embedded systems
Most of the traditional household appliances are controlled by single-chip computers. After upgrading from traditional household appliances to networked home appliances, in order to realize the seamless connection between network technology and home appliance control system, the embedded software with network function and the control software program of single-chip microcomputer are made. The corresponding adjustments make it organically integrated into a complete embedded system.
Second, the technical characteristics of Haier network home appliance system
Haier network home appliance system is a product of mutual integration of home network technology, home appliance control technology and community intelligent technology. From the perspective of satisfying users' needs, it has adopted the internationally mature basic technology and completed the interdisciplinary integration of the above technologies.
In order to realize remote control of household appliances and interoperability of home appliances, it is necessary to solve the problem of home networking and network access. Different from the enterprise network, the home networking also faces some technical problems. For example, the user's networking requirements must be low-cost, easy to install, configure and use, and do not require a lot of technical maintenance knowledge. At the same time, the home networking must also consider the physical transmission medium. The problem is that new homes and old-fashioned homes can be easily networked.
From the perspective of network communication, the home network includes a physical layer, a data link layer, a network layer, a transport layer, a session layer, a presentation layer, and an application layer. The purpose of the physical layer is to stream the original bit stream from a network. The home appliance is transported to another network appliance; the data link layer mainly discusses the transmission of the frame stream on the data link; the network layer mainly handles the transmission of the packet in the network; the task of the transport layer is to provide reliable and economical data from the source. The transfer to the destination; the session layer mainly controls the session between users; the presentation layer mainly deals with the syntax of exchanging data between application entities, the purpose of which is to resolve the difference between format and data representation; the application layer provides access to the OSI environment by the process. method.
The physical transmission media of the network are twisted pair, wire carrier, and wireless (RF). For different physical transmission media, the international market has formed corresponding technical specifications or agreements for home appliances, including LonWorks, CEBus, HomePNA, and HomeRF. LonWorks' complete seven protocols support the above three physical transmission media for automated monitoring systems in all industries. The network topology can be either bus-type or other topology. The protocol is included in its neuron chip. CEBus (EIA600) is a development standard that supports power line carrier, twisted pair, wireless (RF) and cable communication. The main controller performs high-level applications and network management functions. It is connected to the data link layer core controller and the physical layer. The letter is connected. HomePNA (Home Phone Line Network Alliance) intends to adopt a single universal telephone line network alliance standard to quickly provide a series of home network solutions for the market. Its physical layer adopts frequency division multiplexing (FDM) mode. Users can use the existing phone line to connect to computers and other home devices to share Internet access, share data and applications, and share with us. At the same time, normal phone calls can be made.
