This part mainly describes the related technologies, applications and prospects of smart homes.
Bill Gates once said in his 1995 “Road to the Future”: In the future, houses without smart home systems will be as unfashionable as houses without Internet access. Starting in 1990, after 7 years, he built his own smart mansion “House of the Future”. This lakeside villa covering an area of about 6,600 square meters cost 113 million U.S. dollars. At that time, it was called “the smartest house in the world.”, has also become a classic of smart home.
“Future House” is regarded as a model of human life in the future with its unimaginable intelligence and automation at that time: it can remotely control automatic equipment such as baths, air conditioners, and cooking; there is a system for checking the body and automatically alarming in the toilet; When the guests arrive, they will get a pin attached to their clothes, which can automatically convey to the control center the guest’s favorite temperature, TV programs and preferences for movies…
It has been more than 20 years since the “House of the Future” was built. Thanks to the development and popularization of technologies such as the Internet, the Internet of Things, intelligence, informatization, and automation, my country’s smart home market has gradually grown and become a specialized industry. Many Internet companies, home appliance companies, and operators, such as Baidu, Tencent, Xiaomi, Midea, Haier, Telecom, and China Mobile. . . Or it can be combined with real estate or customized by family, and the target customers have shifted from high-end users to the middle class. Today’s smart home products are not only for the “royals”, but also more or less “fly into the homes of ordinary people.”
The reason why smart home can rise is not because of the pleasure of remote control and the coolness of high-end technology, but because it can indeed solve the needs and pain points of customers, and can provide users with a safer, healthy, comfortable and convenient home environment. So it is not difficult to understand its broad market prospects.
The general definition of smart home is: taking residence as a platform, using integrated wiring technology, network communication technology, security technology, automatic control technology, audio and video technology to integrate facilities related to home life, and build efficient residential facilities and family schedule affairs. The management system improves home safety, convenience, comfort, and artistry, and realizes an environmentally friendly and energy-saving living environment. There are mainly two core technologies:
1. Internet of Things
The facility integration of smart homes is not a simple combination of home appliances, but the use of Internet of Things technology to connect various equipment components in the house together, intelligent identification and information interaction through sensors, to achieve home appliance control, lighting control, indoor and outdoor remote control, various functions such as anti-theft alarm, environmental monitoring, air-conditioning control, door and window control, audio-visual control, etc., provide users with intelligent services.
The Internet of Things refers to the real-time collection of any objects or processes that need to be monitored, connected, and interacted through various information sensors, radio frequency identification technologies, global positioning systems, infrared sensors, laser scanners, and other devices and technologies, and their sound Various required information, such as light, light, heat, electricity, mechanics, chemistry, biology, location, etc., can be accessed through various possible networks to realize the ubiquitous connection between things and people, and realize the intelligence of objects and processes.
The Internet of Things is a new generation of information technology based on the Internet and traditional telecommunications networks. It allows all ordinary physical objects that can be independently addressed to form an interconnected network. If the Internet is the interconnection of people, then the Internet of Things pursues the interconnection of everything. As long as there is an unlimited and wireless network, everything in the world is digitized and informatized, and there is an omnipotent sensor interactor, it can be realized.
At that time, the world will communicate with one another. The pig persuaded the butcher: ” Put down the butcher knife and become a Buddha on the spot “; the vegetables are in the refrigerator and the slogan: “I am about to expire, you don’t care about it”; the stone warns the egg: “Don’t touch me, worry about it, don’t let it go after you get hurt. ” Egg white”; rice reminds diners: “Beware, we are mixed with bad guys-sand”; “Flowers splashing tears when feelings, and hate birds are scared” may be the real scene.
These are not science fictions or myths, but our knowledge and technology have not yet been reached. Zhuang Zi said: “My life has a limit, and knowledge has no limit.” According to the well-known quantum physicist David Bohm’s holographic theory of the universe: the universe is a unified whole of holographic connections between parts, and everything is one, interacting and reacting to each other.
2. Artificial intelligence
In addition to the Internet of Things technology, smart homes also have a core technology-artificial intelligence technology. In fact, as far as technology is concerned, there is no independence, and they all complement each other. Artificial intelligence is based on the Internet of Things, and the Internet of Things makes extensive use of artificial intelligence. Of course, these two core technologies also need other technical support to support the smart home system.
A lot has been said before about artificial intelligence. The artificial intelligence requirements of smart homes can be summed up in one sentence: the machine must be smart and able to recognize, memorize, analyze, judge, interact, and act according to the various needs of the user’s home. It is like the leader handing you one thing, it is impossible to tell everything (what to do, how to do it, and what the result is). You need to think, complete, and reflect the value by yourself. Of course, there will be some communication process in the middle. In the current smart home, artificial intelligence technology is mainly reflected in various smart systems (the content of related systems can be deleted or further subdivided according to customer needs):
(1) Intelligent lighting system
Through a variety of intelligent control methods such as remote control, the whole house lighting can be remotely switched to realize various one-key lighting scene effects such as dimming, full on and off, and “meeting, cinema”, etc., achieving energy saving, environmental protection, comfort and convenience Function.
(2) Intelligent scene system
According to user habits and needs, you can set the home mode, away from home mode, morning mode, sleep mode, dining mode, entertainment mode, learning mode, meeting mode, etc.
(3) Smart door and window system
It has the functions of wireless remote control, smart switch, automatic weatherproof, indoor air purification, gas prosecution, fire prosecution, automatic help alarm, smart dynamic glass, etc.
(4) Intelligent voice system
Language is the most important way of communication for human beings. As the Turing test said, if artificial intelligence can achieve indiscriminate dialogue with people, it means that artificial intelligence technology is truly mature and has universal applicability. The human-computer communication method of intelligent voice is more suitable for the elderly and children with relatively weak technology mastery.
According to air quality, temperature and humidity, the indoor environment variables are adjusted with maximum energy efficiency to create a more comfortable, energy-saving and healthy living environment for the home.
(6) Intelligent security system
Including video surveillance, intercom system, door magnetic switch, emergency help, smoke detection alarm, gas leak alarm, broken glass detection alarm, infrared double-check detection alarm, etc., can detect and notify strangers intrusion, gas leaks, fires, etc. in time the host.
In the current smart home market, smart systems and smart items from various manufacturers are in full bloom. However, if we think about it carefully, we will find the real situation of smart technology applications: most smart products are actually just Internet + technology, using remote + information + Automatic control only. Various intelligent systems are set up according to fixed routines. They do not have a complete set of independent actions for recognition, thinking, judgment, and decision-making, and they cannot be separated from human manipulation. The so-called “intelligence” concept is a bit misleading, even if It is also far from the “artificial intelligence” technology that is just starting now.
However, for ordinary civilian use of high-tech technologies, there has always been a delay process: first, high cost; second, technological maturity to be tested; third, the development of application methods also requires a long-term process. The current smart home can only be said to be like a baby who has just landed in the womb in September. The road is long and long, and we can’t immediately count on it to be unparalleled and unstoppable.
Smart home is a future evolution of smart home now. As a result of the real artificial intelligence intervention of human wisdom, smart home has a brain full of wisdom and a certain sense of independence. Through various system networks, technological equipment, and smart items, it serves users in all directions: invasion from outside To the protection of internal disturbances, from outreach to housekeeping services, from physical, physical, and psychological care, from scenes to atmosphere comfort, from virtual entertainment to dream-making entertainment, and guidance from planning to decision-making. . .
1. Central control system
The central control system is the brain of the smart home. Various subsystems are gathered here, responsible for the integration of various systems, energy distribution, overall management and control, mutual coordination, centralized processing, platform upgrades, and cloud interaction. After receiving the information extensively, analyze and judge the situation according to the situation, and issue a unified instruction for the relevant system to execute. This central control system seems to be no different from the current system, but the key is that it is smart and smart enough to protect humans, care for their homes, and solve problems better than humans.
The scientific community generally believes that the world is composed of three major elements: matter, energy, and information. Without matter, nothing exists; without energy, nothing will happen; without information, nothing has meaning.
There is a close connection between information and data. Data is a record that reflects the attributes of objective things, and is a concrete manifestation of information. After data is processed, it becomes information; and information needs to be digitally transformed into data before it can be stored and transmitted.
If the smart home is to be truly realized, it is very important: all the materials, energy, and information related to the home must be digitized, and only on this basis can its wisdom function be exerted. The data collection of smart home should include the home environment and dynamics as well as the user’s work and rest, diet, shopping, health, learning, habits, visitors, etc. Through the mastery of huge data information, analysis and professional processing, the formation of useful information , In order to make predictions on user needs, environment, safety, etc., and provide them to the central control system for decision-making in a timely manner.
Regardless of just a home, the data storage and analysis of the smart home may cover the life of the family user, and the amount of data and information is huge. Therefore, there will be a dedicated cloud public platform to provide data storage and analysis functions, and set corresponding privacy protection and Encrypted interface.
Smart home-home of data
3. Identification system
The recognition system is the key to open the smart building. It is based on the information formed by the big data system. Its basic content includes identity recognition, status recognition, command recognition, etc.
The British “New Scientist” has an article “11 characteristics that make everyone unique”, namely: DNA, fingerprints, face, eyes and iris, ears, heartbeat, brain waves, gait, sound, smell, microorganisms. Different from the limitations of traditional external media such as access control and passwords, the use of human characteristics for system management and control is more accurate and convenient, which is the future development trend. At present, fingerprints, human faces, eye irises, and voice recognition have been applied.
Identify the user through the comprehensive characteristics of the human body such as face, voice, smell, etc. After identification, different privacy levels are determined according to the degree of intimacy with the owner, and different permissions are set. For example, the door and the door can only be accessed by family members. , The safe can only be opened by the couple, and the small vault can only be opened by yourself. Special circumstances require authorization.
(2) State recognition
By distinguishing body movements, micro-expressions and brain waves, etc., it can analyze physical conditions, thoughts and emotions, and judge people’s status and needs. Then the relevant data is transmitted to the data system for analysis, so as to formulate corresponding plans. For example, when the owner is tired at home, the lights and music will automatically adjust to a relaxing effect or rhythm to help relieve fatigue.
(3) Instruction recognition
There are multiple command systems, such as manual remote control commands and voice commands, which are all conventional. But there are also special circumstances, when you can’t send instructions, the smart system will automatically issue instructions based on what you “see” and the information you have.
For example , if you are unconscious when a disease occurs, devices or systems such as smart bracelets that always recognize your physical characteristics and understand your disease history will directly issue early warning instructions to connect relatives to the hospital;
Another example: when someone enters a room for stealing or robbery, the smart system can be like a guardian. After recognizing the situation, the smart system can automatically activate the security system, contact the security or the police, and even make the intruder lose consciousness through hypnosis and brain wave interference.
Some scientists believe that human beings are not so unique, but are actually a biological computer. All behaviors and consciousness are only derived from data and life algorithms. This is what the data-centrists say, but it also has some truth, and things like predictions and fortune-telling can be explained based on this.
Through complete data analysis, the user’s behavior and preferences will be fully judged and cracked by the intelligent system. Starting from opening the door, even without instructions, the smart scene can prepare everything for the user, including commuting, eating, entertainment, studying, sleeping, etc., composed of sound, light, electricity, water, air, audio and video, etc. The scene elements, with every move and smile of the user, start seamlessly.
5. Indoor air conditioning system-vanilla-scented air
The current indoor air-conditioning system, constant temperature and humidity + fresh air, even if the configuration is very good, it is called healthy. But have you thought that indoor air can also have a smell? Mint, lemon, lavender, rosemary fragrance. . . Of course, you can also like the smell of stinky tofu, but you have to pay extra, because it is a special order.
Li Shizhen listed a large number of beneficial vanilla plants in “Compendium of Materia Medica: Fragrance”, which can use fragrance to regulate people’s psychological and physiological functions, change people’s mental state, and achieve the effects of disease treatment and preventive health care.
As people spend a long time at home, future smart air conditioners can use the vanilla-scented air to regulate the body and mind of human beings after obtaining data on the physical and mental condition of the owner through the recognition system. If you are depressed, you will have a scent of excitement. If you are insomnia, you will have a soothing odor, but the dosage should be controlled.
6. Virtual reality-poetry and distance
Virtual reality technology (VR) is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulation environment to immerse users in the environment.
The virtual reality technology of smart homes will not only be able to achieve the level of fake and real, but also interact with people through a simulated environment. In this way, people can experience various beautiful scenes without going out: the green grass looks at the setting sun, the blue waves of willows are long, the dragonfly stops the lotus flower, and the colorful butterfly flutters to show off the neon clothes. If you are still not enjoying yourself, you can also imagine a beautiful woman or handsome guy to chat and enjoy together.
In addition, if humans have mastered the law of forming their own consciousness, just like “Inception”, the data system can completely adopt the form of data interaction, so that people can enter the virtual reality environment when they are hypnotized.
5. Smart Family P (personal)-AI
In the distant future, humans may live very well and happily without needing partners, children or even friends.
Because there is a wise family member P-AI at home, they can laugh, cry, eat, study, work, play, and joke with you. . . They can be imaginary people, things and scenes in your imagination through technological means. The intelligence, wisdom, and physical ability are far beyond you. Any difficult and complicated problems can be entrusted. She/ He will be your friend, teacher, and doctor, accountant, chef, bodyguard, nanny, assistant. . . Even relatives, a superman during the day and a fairy at night, as long as you need it, the key is loyal and reliable, but you are the only one. You can calm down and imagine yourself, isn’t it exciting?
If artificial intelligence is the extension of human wisdom, then the wisdom family P-AI can become the extension of the wisdom of a specific individual on the basis of obtaining the wisdom of the human group. She may be a central control device, or a bionic robot or even a bionic person; she may stay with you for a lifetime, constantly updating and growing up, or it may be upgraded too much and out of trend and be eliminated and replaced (P-AIs may be aging and will be supported by a kind master).
As you get along day and night, P-AI can grasp almost all the data related to you: the mood index of micro-expressions, all kinds of favorite things, the way of thinking and doing things, heartbeat, pulse, brain wave, blood pressure, etc. under different circumstances, psychology and emotion , Joke tolerance and abnormality index, rules of getting up, sleeping, eating, going to the toilet, etc., height, weight, three-dimensionality, fat degree, number of hair, pore size, etc. . . P-AI can use these comprehensive data collection, analysis, calculations, and even build your digital model. By connecting with human consciousness, through continuous calculation and simulation, you can become another intelligent and comprehensively upgraded you.
When artificial intelligence really develops to this day, it is actually very scary. Because of the lack of IQ, human beings are incapable of writing, and their understanding of themselves is not as comprehensive as P-AI, and P-AI is needed to guide one’s life and generate complete dependence and sustenance. By then, humans may really become waste. Especially when artificial intelligence has a “consciousness of independence” similar to humans, it is very likely that hegemonic thoughts will appear, which in turn will enslave mankind. Therefore, the “Three Principles of Machines” proposed by the “Father of Robotics” Asimov is very necessary:
1. Robots must not harm humans, or stand by while seeing humans being harmed;
2. The robot must obey the order of the human, unless this order contradicts the first one;
3. The robot must protect itself, unless this protection contradicts the above two items.
Smart Family P-AI
Ever since artificial intelligence killed the world champions who are good at brainpower, many people have a premonition that mankind will enter a new era, and the future may change. Hawking once said: “Making a machine that can think is undoubtedly a huge threat to human existence. When artificial intelligence is fully developed, it will be the end of mankind. “Despite the alarmist, there is no need to worry about the world, especially in the current situation of artificial intelligence. When the Dou is not open, mankind has time to discipline and make good use of it.
Undoubtedly, smart and smart homes will bring earth-shaking changes to our home life, but this industry is just in the ascendant, hardware, software, standardization, decoration, etc. are all immature, and the main level of intelligence is still weak, and even basic voice There are difficulties in semantic recognition, let alone accented, whole point dialects. But with the continuous advancement of technology, these will gradually improve. What we should see is that artificial intelligence can meet the needs of users to the greatest extent and can bring people more beautiful lives.
