From the perspective of social benefits, the application and promotion of smart grid user-side services and user-oriented information services will bring good social benefits; the application of smart power community equipment will improve the government's management efficiency for residents; The system composed of equipment in the electric cell can improve the reliability, availability and overall efficiency of the entire power grid. From the perspective of economic benefits, it will save investment in electricity for the country; it will save electricity bills for users; it will stimulate domestic demand and bring social and economic benefits. After years of development, the company's smart electrical products have developed and accumulated to a certain extent; it has formed smart home gateways, smart socket core hardware, and four categories of smart life housekeeper software: PC, tablet, mobile phone, and set-top box.
The communications industry has a surprisingly similar trajectory. The rapid rise of smart phones in the wireless communication market in 2008 has ended the era when mobile phones only made calls and sent text messages, and announced the arrival of a new era of mobile Internet. Since 2001, the home broadband market has experienced two construction climaxes of "DSL broadband and optical network city", and it has also ushered in a moment of qualitative change. The emergence of a new generation of home connection and control centers represented by smart home gateway products has declared The arrival of a new era of smart home.
The gateway is the heart of home intelligence, through which the collection of system information, information input, information output, centralized control, remote control, linkage control and other functions are realized, so as to realize the control of home smart appliances, such as: smart switches, smart TVs, smart curtains and other smart home products.
At present, smart home devices are interconnected through two gateways and three methods. 2 gateways are Bluetooth gateway, ZigBee based IoT gateway, 3 connection methods are Bluetooth connection, ZigBee connection, Wi-Fi connection (no gateway required).
In fact, the smart home gateway has two functions: smart home control hub and wireless router. One side is responsible for specific security alarms, home appliance control, and electricity consumption information collection. Data interaction with products such as intelligent interactive terminals through wireless means.
The smart gateway is an indispensable part of the smart home. It can realize the operation of the entire smart home system. Its functions include not only the collection, input, and output of information, but also remote and linkage control. Therefore, for consumers, the quality of the smart gateway determines the overall experience of the purchased smart home products.
The intelligent gateway has the ability to access the network. First, it has the function of obtaining information such as the attributes and status of each node, and can perceive the real-time status of each node. Secondly, it has functions such as remote control, wake-up, and diagnosis of nodes. Thirdly, it also has the intercommunication capability between different networks. There must be a requirement for cross-domain communication when accessing an intelligent gateway. Therefore, a complete addressing technology is required to ensure that the information of all nodes can be accurately located and queried. Fourth, the intelligent gateway must realize the protocol conversion from the sensor network to the traditional communication network, uniformly encapsulate the standard format data transmitted on the protocol adaptation layer, unpack the data sent by the wide area access layer into standard format data, Realize the analysis of commands, and then convert them into signals and control instructions that can be recognized by the perception layer protocol.
To put it simply, the smart gateway mainly completes three tasks. First, it collects data from sensor nodes; second, it performs data protocol conversion; and finally, it quickly sends the data after protocol conversion to the public network. In addition, it should also have corresponding management and control capabilities.
2. Main functions of smart home gateway
The smart home gateway has the two functions of smart home control hub and wireless router. One side is responsible for specific security alarms, home appliance control, and power consumption information collection. Data interaction with products such as intelligent interactive terminals through wireless means. It also has wireless routing function, excellent wireless performance, network security and coverage area, the smart home gateway is an ideal choice for your wireless home network.
2.1 Abundant smart home management functions
Mobile phones, PADs, and various devices can easily control home appliances and smart home hub devices through it.
The smart home system is one of the core businesses of power fiber-to-the-home. It is a comprehensive management system integrating remote control, energy consumption management, and intelligent power consumption. Users can install the "smart home steward" software through mobile phones and computers, log in to the operation center for management, and remotely control the electrical equipment at home, improving the safety and temporaryness of home electricity use. At the same time, you can also view the surrounding community services, telemedicine, video movies, etc. through our software. Smart home is based on the residence as a platform, using integrated wiring technology, network communication technology, smart home-system design security technology, automatic control technology, audio and video technology to integrate home life-related facilities to build efficient residential facilities and family schedules The business management system improves home safety, convenience, comfort, and artistry, and realizes an environmentally friendly and energy-saving living environment.
2.2 High-speed and stable wireless routing
Integrating wireless router functions, you can enjoy the fun of surfing the Internet anytime, anywhere.
3. The role of smart home gateway
Before getting to know the gateway, it is necessary to understand the networking principle of the smart home: In fact, these smart home devices are interconnected through two gateways and three ways. The two gateways are Bluetooth gateways and ZigBee-based IoT gateways, and the three connection methods are Bluetooth connections, ZigBee connections, and Wi-Fi connections (no gateway required).
So since it can directly pass through the WIFI at home, what do you need the gateway for? We have found that WIFI-connected hardware devices are particularly reliant on wireless networks. Your home wireless network needs to be stable and reliable. Otherwise, you will often encounter phenomena such as offline devices and lost connections. Usually there are more relatives and friends at home, and when there are more mobile phones connected to the router, the wireless network will be stuck. In addition, if the telecommunications broadband fails or the router is powered off, the smart devices at home will also become decorations. Now that the Wi-Fi network is flawed, how about the other two devices connected through the gateway. The gateway is actually a bridge, which can not only connect to the WIFI network, but also connect to other smart devices at home through its own network.
3.1 ZigBee gateways and Bluetooth gateways are particularly power-saving, and the sub-devices can be made very small without plugging in, and the battery can handle it.
3.2 The ZigBee gateway can exist apart from the home broadband network, even if your router fails. The preset automatic associated operations and alarms will not be affected (for example, the temperature and humidity sensor detects that the house is dry and turns on the humidifier).
3.3 ZigBee can easily expand the network coverage to dozens of times through the relay, and the transmission distance is farther.
Two major functions
The smart home gateway has the two functions of smart home control hub and wireless router. One side is responsible for specific security alarms, home appliance control, and electricity consumption information collection.

4. Is smart home gateway important?
The smart gateway is the core of the smart home, and it is the system control center that realizes the intelligentization of the home. Through the smart gateway, functions such as system information collection, information input, information output, centralized control, remote control, and linkage control are realized.
The smart gateway is interconnected with home devices and smart terminal devices. It can be remotely controlled when watching TV, controlling the air conditioner or opening the curtains, or when you are not at home and monitoring through the camera. The smart gateway seems to play an important role in home intelligence. The central role of connection and control is extremely important. It is considered to be the focus of the smart home melee, and has become the focus of market competition for telecom operators, Internet companies and some core home appliance manufacturers.
The realization of smart connection in smart home requires the processing of cloud server, and the smart gateway as the central control, so that mobile phones or other smart terminals can control smart home products. For example, take the smart light control system as an example. When I plan to turn on the living room light remotely, I operate it on the mobile APP, and the signal will be uploaded to the cloud server. After the cloud server processes the command, it will send the command back to the smart gateway. The gateway accepts instructions and controls smart home products. The networking control of the entire smart home product needs to be processed by the smart gateway, which is particularly important in the smart home system.
