Smart home is to take the residence as the platform, integrate the integrated wiring arrangement and other technologies with the home equipment, so as to form an efficient and intelligent residential equipment integration management system and enhance the home security and convenience.
Definition and Classification of Smart Home Smart home is to take the residence as a platform and integrate technologies such as integrated wiring arrangement, network communication technology, home appliance automation, Internet of Things, cloud computing and artificial intelligence with home equipment, so as to form an efficient and intelligent integrated management system of home equipment to enhance the security, intelligence, comfort, energy saving and convenience of home environment.
At present, smart home covers home security monitoring, intelligent audio, video entertainment equipment, temperature control equipment, intelligent lighting and large and small home appliances, etc. Due to the advantage of user scale, the market of smart home equipment has a broad prospect.
The market scale is nearly 1 billion units
Data show that the global smart home device shipments in 2020 reached 854 million units, of which: smart entertainment video, home security monitoring, smart speakers for the larger shipments of smart home devices in 2020, the 2020 shipments of 353.9 million units, 166.3 million units, 133.7 million units. Global smart home device shipments are expected to reach 973 million units in 2021.
Compared with traditional home products, smart home develops home products from passive static type to active intelligent type through data interaction and remote control and other functional forms
Smart home industry key technology – wireless communication technology
Among the wireless communication technologies, Zigbee, Wi-Fi and Bluetooth are most widely used in the smart home industry, and their market shares in the smart home wireless communication technologies in 2018 are 24%, 19% and 5%, respectively.
As different smart home wireless communication technologies vary in dimensions such as transmission speed, communication distance, power consumption level and module cost, there are differences in the application areas where smart home communication technologies and their communication protocols are used
Since smart home devices have three characteristics of networkability, perceivability and intelligence, the upstream link of smart home can be divided into transmission layer, perception layer and processing layer.
Wireless communication chip is the core component of transmission layer, which directly reflects the mainstream technology line and product performance. Due to the different network communication technologies and network protocols applied in smart home products, and the industry is difficult to achieve unified communication protocol standards in the short term, there are differences in wireless communication technologies and chip types applied in smart home devices.
Throughout the smart home wireless communication technology types, Zigbee, Wi-Fi and Bluetooth three wireless communication are most widely used in the smart home field.
With the continuous development of the industry, the development of smart home has also changed quietly. From the initial smart home single product, which can only control the lights or air conditioner single appliance at home, to the later intelligent scenario linkage, gradually evolved into whole house smart home, smart community and so on. Here, let’s take a look at what new ecology has sprouted from smart home.
1, product, smart home products began to pay more and more attention to content and personalized services. On the basis of data analysis, the user portrait will become more and more refined, and the usage data of various smart products will further provide data support to the upstream and downstream enterprises in the supply chain, thus prompting the integration and development of each industry chain. For example, the air box provided by intelligence, through analysis of user usage data, can provide more personalized intelligent home solutions under changes in the temperature and humidity of the indoor environment and other conditions, when the air box detects deviations in air temperature, humidity and preset values or harmful gases exceed the standard, can be intelligently linked to open the air conditioner or air purifier.
2, home appliances and user interaction, smart home intelligence is not just to provide convenience, but actually provides an entrance for intelligent products to interact with users. For example, the use of indoor terminals at home can communicate with the community; not at home, if there are strangers visiting the home, you can call transfer to the phone, door magnetic sensors and human infrared sensors can also be pushed to the phone alarm immediately when there is a thief invasion, etc.
3, prompting traditional home appliance companies to embrace the new ecology of smart home. The irreversible trend of smart home prompted smart home manufacturers and Ali and other Internet technology giants to be more open to cooperation, making the product intelligent transformation more rapidly. Traditional home appliances want to use also smart, then you need an infrared transponder, so that traditional appliances become smart appliances in seconds. To sum up, smart home is changing people’s social, entertainment, health, consumption and living habits to a certain extent, and people are getting more and more enthusiastic about intelligence.
Smart home industry development opportunities
With its organic combination of home appliance control, environmental monitoring, information management, audio and video entertainment and other functions, smart home devices can provide a more convenient, comfortable, safe and energy-saving home living environment through the centralized management of home equipment, which is increasingly recognized and accepted by the majority of consumers and has become a hot product in the field of intelligent terminals in recent years.
Smart home market is still in the early stage of development, but it has a certain scale globally and is growing rapidly, with huge market space in the future.
