Smart Home Concept Diagram
Many people may think that what I said is not a movie scene? In the past, these scenes can only happen in science fiction movies. Now, with the development of smart home industry, these scenarios have started to come out of the screen and “fly into ordinary people”s homes”.
I. Smart home concept
Smart home (English: smart home, home automation) is a residential platform, the use of integrated wiring technology, network communication technology, security technology, automatic control technology, audio and video technology will be home life related facilities integration, build efficient residential facilities and family schedule affairs management system, enhance home security, convenience, comfort, artistry and realize the environment-friendly and energy-saving living environment.
II. Background of Smart Home Development
The concept of smart home was put forward early, but no specific architectural case has appeared until 1984 when United Technologies Building System applied the concept of informationization and integration of building equipment to the Hartford, Connecticut (USA) CityPlaceBuilding. The first “smart building” emerged when United Technologies Building System applied the concept of informationization and integration of building equipment to the CityPlaceBuilding in Hartford, Connecticut, U.S.A., which opened the curtain of the world”s competition to build a smart home.
The smart home is the embodiment of the Internet”s influence on the connection of things. Smart home connects various devices at home (such as audio and video equipment, lighting system, curtain control, air conditioning control, security system, digital cinema system, audio and video server, movie cabinet system, network home appliances, etc.) together through Internet of Things technology to provide home appliance control, lighting control, telephone remote control, indoor and outdoor remote control, anti-theft alarm, environmental monitoring, HVAC control, infrared forwarding and programmable timing control The smart home provides a variety of functions and means such as home appliance control, lighting control, telephone remote control, indoor and outdoor remote control, burglar alarm, environmental monitoring, HVAC control, infrared forwarding and programmable timing control. Compared with ordinary home, smart home not only has the traditional residence function, but also the building, network communication, information appliances and equipment automation, providing a full range of information interaction functions, and even saving money for various energy costs.
Third, the core of smart home – home automation
Smart home is to better serve human family life and make it more convenient and fast for people to use household appliances. Smart home separates people from the traditional mode of using home appliances and puts more emphasis on intelligence and home automation.
Home automation is an important trait of smart home. When smart home first appeared, home automation was even equivalent to smart home, and today it is still one of the core of smart home, but with the general application of network technology in smart home and the maturity of network appliances/information appliances, many product functions of home automation will be integrated into these new products, thus making pure home automation products in system design less and less, and its core position will be replaced by the home network/home information system. It will function as the control network part of the home network in the smart home.
Home automation refers to the use of microprocessor electronics to integrate or control electrical and electronic products or systems in the home, such as lighting, coffee stoves, computer equipment, security systems, heating and cooling systems, video and audio systems, etc. A home automation system mainly uses a Central Processor Unit (CPU) to receive messages from the relevant electrical and electronic products (changes in external environmental factors, such as changes in light caused by sunrise or sunset, etc.) and then sends appropriate messages to other electrical and electronic products in a defined program. The central microprocessor must control the electrical products in the home through a number of interfaces, which can be keypads, touch screens, buttons, computers, telephones, remote controls, etc.; consumers can send signals to or receive signals from the central microprocessor.

Smart home market scale from 2012 to 2020
V. Difficulties faced by smart home in China
Smart home is a relatively mature market in many countries in Europe and America, but it has just started in China, and it is mainly concentrated in first-tier cities. With the intensification of population aging and the liberalization of the two-child birth policy, the proportion of the elderly and children in the population further increases, and there is still a lot of potential in the smart home market waiting to be tapped. The scale is 40.340 billion yuan, and will reach 130 billion yuan by 2018, with a compound annual growth rate of about 48%.
In foreign countries, Apple and Google are fighting with each other, and in China, BAT, Jingdong, Xiaomi, Haier and other armies are involved, so the smart home field has obviously become the main battlefield for the giants.
Sixth, the reasons for the obstruction of smart home
Taking smart home appliances as an example, there are two main reasons leading to the status quo of smart home market.
One is that users need to wait for the replacement cycle of home appliances.
Second, the value of the appliances connected to the Internet of Things to consumers has not been fully reflected, such as ordering milk through the refrigerator such a service, for users, so smart to order milk services, compared to the high price of smart devices, they are more willing to cell phone to order milk, coupled with the status quo take-away APP is also very popular and convenient.
So to sum up, the obstacles to the development of smart home are mainly reflected in the following aspects.
① Lack of uniform standards in the smart home industry.
② Complicated operation for the elderly group.
③ High cost of smart devices.
④ Intelligent functions are not irreplaceable.
⑤ Lack of ecosystem support.
There is a view in the industry that the misconception of smart home is that it is now smart for the sake of smart, staying at a geeky level, and the traditional life pattern of Chinese residents and their own economic level make them feel that smart home is dispensable. The key is that there is not a market breakthrough in smart home that really triggers this market. Some information shows that there are many small enterprises doing smart home in North China, and a number of them have “died on the beach”. The reason why they fall down is that these enterprises do not grasp the pain points of consumers, that is to say, there is no killer application to attract consumers.
Seven, the relationship between artificial intelligence and smart home
Artificial Intelligence (AI), abbreviated as AI, is a new technical science that studies and develops theories, methods, technologies and application systems for simulating, extending and expanding human intelligence.
Many smart home manufacturers are already working on home intelligent robots, which can be called “intelligent housekeepers”, the core technology of manufacturing “housekeepers” is not cameras, motors, processors, communication chips, but highly artificial intelligence algorithms. Neural networks, deep learning, computer vision, etc. …… Including voice recognition, text recognition, face recognition, machine learning natural language, etc.
1, the relationship between artificial intelligence and smart home can be divided into three stages: control – feedback – integration
the first level is control: that is, remote switch, timer switch and other control methods.
The second level is feedback: the data obtained through smart home or wearable device is fed back to the owner through smart housekeeper, “watch TV a little too much in recent days oh”.
The third level is integration: when the master talks to the intelligent butler about other things, the intelligent butler knows that the master is in a bad mood, so it can ask the master if he wants a piece of music, or directly play a piece of music that the master usually listens to the most.
Iron Man and artificial intelligence butler
2、Artificial intelligence butler
Users can choose and customize the artificial intelligence butler they want according to their needs. The artificial intelligence butler, which is familiar with all the owner”s preferences and habits, will always activate the right appliances at the right time. Just like Iron Man”s intelligent butler Jarvis, it can receive all instructions from the user and complete them accurately, such as opening the door, turning on the TV, air conditioning, etc. Not only that, it can also chat with you when you are bored. We can imagine, home without keys, the camera automatically identify open the door, butler automatically turn on the lights, help you turn on the TV search channels. Not at home, there is a butler to guard the safety of the home, there will be no theft of fire and other accidents. No wiring without installation, you can have a smart home butler that can separate and combine to control and also speak, does this sound wonderful?
Eight, smart home will enter a new era of artificial intelligence
Artificial intelligence technology helps computers to think, make machines more like humans, and let machines replace humans on a larger scale. How will artificial intelligence and smart home be integrated? In some smart home experience halls, we will find that smart home companies have already used artificial intelligence technology. Let their artificial intelligence technology embed to more life scenes, so as to create an ecosystem of intelligent life scenes.
