Smart home is a kind of living environment for people. The smart home system is installed on the platform of residence, which makes family life safer, energy-saving, intelligent, convenient and comfortable. Taking residence as a platform, integrated wiring technology, network communication technology, smart home-system design security technology, automatic control technology, audio and video technology are used to integrate the facilities related to home life, and build an efficient management system for residential facilities and family schedule affairs, so as to enhance the safety, convenience, comfort and artistry of home and realize an environment-friendly and energy-saving living environment.

Smart Home, also known as smart house, is often expressed in foreign countries. Similar to smart home, there are Home Automation, Electronic Home, E-home, Digital Family, Home Net/Networks for Home, Network Home and Intelligent Home/Building.

Smart home system makes life easy for you. When you go out, you can remotely control your home intelligent systems by telephone and computer, for example, turn on the air conditioner and water heater in advance on your way home; When you open the door at home, with the help of the door magnetic or infrared sensor, the system will automatically turn on the street light, open the electronic door lock at the same time, disarm the security, and turn on the lighting lamps and curtains in the home to welcome you back; When you get home, you can easily control all kinds of electrical equipment in the room by using the remote control, and you can choose the preset lighting scene through the intelligent lighting system to create a comfortable and quiet study when reading; Create a romantic lighting atmosphere in the bedroom ... All this, the owner can sit on the sofa and operate calmly. A controller can remotely control everything at home, such as pulling curtains, draining the bath and automatically heating and adjusting the water temperature, adjusting the curtains, lights and sound. status; The kitchen is equipped with a videophone, so you can answer the phone or check the visitors at the door while cooking; When working in the company, the situation at home can also be displayed on the office computer or mobile phone, and can be viewed at any time; The door machine has the function of taking pictures. If there are visitors when there is no one at home, the system will take photos for you to come back and inquire.

Intelligent lighting
Choose lighting control, press a few buttons to adjust the lighting of all rooms, and create all kinds of dreamy lights at will! Intelligent lighting system has soft start function, which can make the light gradually bright and dark; Light dimming can realize the function of dimming, let you share warmth and romance with your family, and at the same time have the effect of energy saving and environmental protection; Full-open and full-close function can easily realize one-key full-close and one-key full-open functions of lamps and electrical appliances, and has brightness memory function.

Simple installation
The smart home system can be installed simply, without destroying the partition wall and buying new electrical equipment. The system can be connected with the existing electrical equipment in your home, such as lamps, telephones and household appliances. All kinds of electrical appliances and other intelligent subsystems can be controlled at home, and can fully satisfy remote control.

Smart home system is an extensible system. Initially, your smart home system can only be connected with lighting equipment or common electrical equipment, and it can also be connected with other equipment in the future to meet the needs of new smart life.

Even if your home has been renovated, it can be easily upgraded to smart home. The wireless control smart home system can realize intelligent control without damaging the original decoration, and only by installing corresponding modules in some sockets, and it will not damage the original house wall.

Design principle
Smart home is also called smart house. Generally speaking, it is a networked intelligent home control system which integrates automation control system, computer network system and network communication technology. Measuring the success of an intelligent system in a residential district depends not only on the number of intelligent systems, their advancement or integration, but also on whether the design and configuration of the system are economical and reasonable, whether the system can run successfully, whether the system is convenient to use, manage and maintain, and whether the technology of the system or product is mature and applicable. In other words, it is how to exchange the maximum efficiency with the least investment and the simplest way to achieve a convenient and high-quality life.

In order to achieve the above goals, smart home system design should follow the following principles:

Practicality and convenience
The basic goal of smart home is to provide people with a comfortable, safe, convenient and efficient living environment. For smart home products, the most important thing is to take practicality as the core, and abandon those flashy functions that can only be used as furnishings. The products are mainly practical, easy to use and humanized.

We believe that when designing smart home system, we should integrate the following most practical and basic home control functions according to the user's demand for smart home functions, including smart home appliance control, intelligent lighting control, electric curtain control, anti-theft alarm, door access intercom, gas leakage, etc., and at the same time, we can also expand service value-added functions such as three-meter cc and video on demand. For a lot of personalization.

The control methods of smart home are rich and varied, such as local control, remote control, centralized control, mobile phone remote control, induction control, network control, timing control, etc. The original intention is to let people get rid of tedious affairs and improve efficiency. If the operation process and program settings are too cumbersome, it is easy for users to have rejection psychology. Therefore, in the design of smart home, we must give full consideration to the user experience, pay attention to the convenience and intuition of operation, and it is best to adopt a graphical control interface, so that what you see is what you get.

Each intelligent subsystem of the whole building should be able to operate 24 hours a day, and the safety, reliability and fault tolerance of the system must be highly valued. For each subsystem, take corresponding fault-tolerant measures in terms of power supply and system backup to ensure the normal and safe use, good quality and performance of the system, and have the ability to cope with various complex environmental changes.

Standard nature
The design of smart home system should be carried out in accordance with the relevant national and regional standards to ensure the extensibility and expansibility of the system. The standard TCP/IP protocol network technology is adopted in the system transmission to ensure the compatibility and interconnection between different manufacturers. The front-end equipment of the system is multifunctional, open and extensible. For example, the system host, terminal and module adopt standardized interface design, which provides an integrated platform for external manufacturers of home intelligent systems, and its functions can be expanded. When functions need to be added, it is unnecessary to excavate the pipe network, which is simple, reliable, convenient and economical. The system and products selected in the design can enable the system to communicate and interconnect with the third-party controlled equipment that will develop continuously in the future.

Whether the wiring installation is simple or not is directly related to the problems of cost, extensibility and maintainability. It is necessary to choose a system with simple wiring, which can be wired together with residential broadband during construction, which is simple and easy; Equipment is easy to learn and master, and easy to operate and maintain.

The convenient design of the system in engineering installation and debugging is also very important.

Home intelligence has a remarkable feature, that is, the workload of installation, debugging and maintenance is very large, which requires a lot of manpower and material resources, which has become a bottleneck restricting the development of the industry. To solve this problem, the convenience of installation and maintenance should be considered when designing the system. For example, the system can be debugged and maintained remotely through the Internet. Through the network, not only the residents can realize the control function of the home intelligent system, but also the engineers can check the working condition of the system remotely and diagnose the faults of the system. In this way, the system setting and version updating can be carried out in different places, which greatly facilitates the application and maintenance of the system, improves the response speed and reduces the maintenance cost.

Data security
With the gradual expansion of smart home, more and more devices will be connected to the system, which will inevitably produce more operational data, such as air conditioning temperature and clock data, indoor window switch status data, gas meter data and so on. These data have an unprecedented degree of correlation with personal family privacy. Inadvertent data protection will not only lead to the leakage of extremely private data such as personal habits, but also the leakage of data related to family safety, such as window status, will directly endanger family safety. At the same time, the smart home system is not isolated from the world, and the data entering the system should be examined to prevent malicious damage to the home system, and even to the networked home appliances and equipment. Especially in today's big data era, we must prevent the security of home big data.
