Read the smart home in one article

In 2015, there was a high-frequency hot word that constantly hit people's eyes, that is, "smart home." The author has no doubt about the arrival of this reality. It is only that we have not seen this step yet. It is quite a long way to say that "smart home" is still a long way from us.

In order to make this clear, we can first talk about what kind of form "smart home" is probably. Since it is called intelligence, it must be a system of thinking, learning, judging, and analysis. As for the ordinary concept of home, everyone is familiar with it and will not repeat it. Let's talk about what the smart home should do and what it can do. Simply put, "smart home" should create a safe, comfortable, environmentally friendly and energy-saving environment for people; provide people with appropriate health care and health functions; and make people do not forget to do it in a relaxed and happy life. Can't do things that you accidentally did. With the limited knowledge of the author, standing on the technical level of today, the "smart home" can only be described as such, in the long run, these may not be enough. What can be done for "smart home", I think it can at least replace people to adjust and control the system in the home; keep appropriate data records and analyze the completion of the system; alarm for emergencies, Remind, lock; record, analyze, and display daily trivial matters. According to this, "smart home" is a large system project, which contains "brains", "nerves", "hands and feet", which is the one or two of the "smart homes" that I can now see. Compared with the complete form of smart home, this one two two may be a drop in the ocean. The "brain" referred to here should belong to various forms of computers, microcontrollers, MCUs, CPUs, etc. Their status and role is the core of the relevant functional circuits - the brain that sends, receives or processes instructions; The nerves are not allowed to be all kinds of network and data acquisition signal lines. As for the "hands and feet", it is better to understand, that is, the terminal's actuator.

If you basically agree that "smart home" should do and can do this, then we will talk about how to implement the system in the smart home. In order to create a safe, comfortable, environmentally friendly and energy-saving environment for people, “Smart Home” can effectively manage the entry and exit personnel through the security settings of the system, such as the necessary identity registration, certification and documentation for visiting newcomers. The registered personnel enter and exit, carry out routine records, analyze the law, and find the abnormality promptly; promptly authorize the access control system to prevent unrelated personnel from entering and leaving the management area at will; implementing the access system for flammable gases and substances, there is no corresponding measure Do not allow access; timely alarms for abnormal smoke, heat, fire and harmful gases, to remind people to extinguish and protect; to use outdoor sound and light to remind the lock door and so on.

Through the comprehensive regulation of the system, the constant temperature and constant humidity can be realized as stable and long-lasting as possible; the fresh air in the room is changed occasionally, and the gas components in the room, such as the percentage of PM2.5, carbon dioxide, nitrogen and oxygen, are monitored all the time. Automatically switch the corresponding equipment; carry out a certain range of monitoring of the smoke emitted by the households, carry out the management of the first treatment and discharge after necessary, enter the timely warning of the building materials containing radioactivity, monitor the sound pressure of the noise, and find the noise exceeding the standard. The source promptly reminds the property personnel to deal with it; continuously monitors the energy consumption and finds that the abnormality promptly reminds the user to collect and utilize the rainwater and make a reasonable partial utilization of the household washing water.

Through the personalized setting of the system, unique reminders and reminders can be realized, such as: wake up, wake up, add clothes, indoor and outdoor air drying index, UV intensity, outdoor wind direction, weather trends, and appropriate time for exercise. Remind the elderly to take medicine, eat, eat fruit mix and exercise activities guide; carry out the relevant food calories, fat content, how much of the amount of cholesterol; remind owners to pay, take documents or collect relevant data; remind the outgoing residents to board on time Selected vehicles; display daily life information in public areas.

By adding related terminal equipment in the system, measuring the basic parameters of the human body, monitoring the change rules, and notifying the relevant family members of the abnormal situation, the relevant data is recorded truthfully under normal circumstances, and regularly provided to the user or the medical network designated by the user; Lighting, timely switching off the wind, lighting and access control of the unmanned area, locking the status and opening the safety monitoring equipment.

The above mentioned, it may seem trivial, but "smart home" is to free people from simple and repetitive tedious things, just to do these fine and repetitive things, it is computer-centric The long term of "smart home". To successfully complete these tasks, you can use the more mature 4-20mA sensors and new data acquisition equipment, or you can use a single-chip computer and DSP to form a functional group with a certain range, you can also use the home computer. It is used to make electrical appliances in the LAN control room, and even use mobile phones and WiFi to operate home appliances. Among the many control methods, I personally think that it is better for the household to carry out the basic setting and setting of the primary, and then the smart home system automatically runs and adjusts according to the owner's intention, including certain fault tolerance and error correction. In the range set by the user, the self-adjustment is completed, which truly reflects the intelligence, automation and normalization of the smart home. Don't make it necessary for the user to register, log in, enter the password everywhere, and it is not appropriate to have the user's mobile phone control switch and resize. This kind of operation is much more. Instead, people are placed as slaves to control the system. When complex, people can't enjoy the fun and convenience of intelligence. Naturally, they will not be interested in smart homes and even have a need.

Next, talk about "industry partitions." Materials and Technology --- Today, with the rapid development of new materials and new technologies, new technologies have laid the foundation for the birth of new materials, and the improvement and improvement of various materials has spawned new technologies. For example, the technical improvement of poor glass insulation has led to the development and production of “insulating glass”; because of the problem that glass does not block light, the use of electronically controlled light-changing glass has been promoted; due to environmental protection and energy-saving requirements, it has triggered The development of Fu glass. There is no direct correlation between the products and technologies listed here, but the progress and development of modern society has quickly established a link between the two. The original irrelevant “industry partition” has now been broken, without industry. Today, the application of new materials has brought opportunities for the promotion of new technologies. In the current development of new real estate, a large number of double-layer insulation glass is used to reduce heat loss and improve the effect of air-conditioning use. Reduce; the next step of "light-volt glass" promotion, can provide a certain amount of electrical energy for energy-saving lamps, which can be regarded as another function of the future smart home, if the correlation between the two is utilized Is it a better way to develop an intelligent product that is automatically controlled when the lighting is weak and the light is dark when the light is dark? Is it better than the smart product that controls the brightness and color of the light? This led to another topic - architecture and control. Smart home is a part of a building. All smart homes are concentrated in one building, which brings new control and management requirements to the building. Overall energy saving, environmental control, safety management, flexible communication, etc. The realization of these functions needs to be carefully considered from the design link, instead of considering the completion of the building, and then slotting and punching in the post-renovation. Therefore, smart home is a systematic project that requires multiple industries and multiple disciplines. , a variety of technology joint operations. Now the real estate development, some have already walked in front, pre-empting the equipment space that the user may need to enter the home, the basic network is installed, if on this basis, then the wireless router is also like the fire alarm probe Uniform installation, do a unified coordination, protection, reduce many unsafe elements, free up more space, and let more benefits to users, is it a good thing with the best of both worlds?

Finally, I went back to the "brains", "nerves" and "hands and feet" mentioned above. Now the smart products we see are really good. Many home appliance manufacturers are gearing up to the research and manufacturing of smart home products. It is a gratifying good phenomenon for the country, enterprises and users. Our quality of life needs to be improved. To keep moving forward, we must respond to the “innovation” that the government calls for, from theoretical innovation to technological innovation and product innovation. To service innovation, we must keep pace with the times. We must say that "smart home" is still a long way from us. Because we can see, hear, and use most of the terminal's execution components. Things are similar to previous relays, contactors, and switches. They belong to the "hands and feet" of smart homes, because only these are not enough. The application research of "brains" and "nerves" is still relatively few, and these are just smart. An important part of the home, our lack of these aspects today will certainly provide opportunities for foreign manufacturers, and ultimately make us fall again Their back, and the formation of people have watermelon, sesame horrors we pick up. The realization of smart home is not a one-day imagination, nor is it a success. It should be the product of the greatness of our national wisdom.
