It uses residential as a platform to install a smart home system to realize safer, energy-saving, intelligent, convenient and comfortable family life. Using residential as a platform, using integrated wiring technology, network communication technology, smart home-system design security technology, automatic control technology, audio and video technology to integrate facilities related to home life, build efficient residential facilities and family schedule management The system improves home safety, convenience, comfort, and artistry, and realizes an environmentally friendly and energy-saving living environment.

Also known as smart house, it is often referred to as Smart Home abroad. Similar to the meaning of smart home, there are home automation (Home Automation), electronic home (Electronic Home, E-home), digital home (Digital Family), home network (Home Net/Networks for Home), network home (Network Home), Intelligent Home/Building (Intelligent Home/Building) is also called digital home and digital home in areas such as Hong Kong and Taiwan.

Smart home system allows you to enjoy life easily. When you are away, you can remotely control the smart systems of your home through your phone or 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 sensor or infrared sensor, the system will automatically turn on the aisle lights At the same time, open the electronic door lock, security and disarm, turn on the lighting fixtures and curtains at home to welcome you when you return; back home, use the remote control you can conveniently control various electrical equipment in the room, you can choose the preset through the intelligent lighting system The light scene of the study creates a comfortable and quiet study room when reading; a romantic lighting atmosphere is created in the bedroom…All of this, the owner can sit on the sofa and operate calmly, and a controller can remotely control everything in the house, such as drawing curtains and discharging water in the bathtub. It also automatically heats and adjusts the water temperature, adjusts the status of curtains, lights, and speakers; the kitchen is equipped with a video phone, you can make a meal while making calls or check the visitors at the door; when you are working in the company, the situation at home can also be displayed Check it at any time on the office computer or mobile phone; the door phone has the function of taking pictures and taking pictures. If there are visitors at home when no one is at home, the system will take pictures for you to come back and check.

Random lighting

Control the arbitrary lighting control, you can adjust the lighting of all rooms with a few buttons, and all kinds of dream lights can be created at will! The intelligent lighting system has a soft-start function, which can make the light gradually brighter and dimmed; the light dimming can realize the brightness and dimming function, allowing you to share the warmth and romance with your family, and has the effect of energy saving and environmental protection; the full on and off function can be Easily realize the one-key full-off and one-key full-on functions of lights and electrical appliances, and have the function of brightness memory.

Simple installation

The smart home system can be easily installed without destroying the partition wall or purchasing new electrical equipment. The system can be connected to the existing electrical equipment in your home, such as lamps, telephones, and home appliances. Various electrical appliances and other intelligent subsystems can be controlled at home, and can also fully satisfy remote control.


The smart home system is an expandable system. Initially, your smart home system can only be connected to lighting equipment or commonly used electrical equipment, and it can also be connected to other devices in the future to meet the needs of new smart life.

Even if your home has been renovated, it can be easily upgraded to a smart home. The wirelessly controlled smart home system can not damage the original decoration, as long as the corresponding modules are installed in some sockets, etc., the smart control can be realized, and it will not cause damage to the original house wall.

Design Principles

Smart home is also called smart house. In layman’s terms, it is a networked intelligent home control system that integrates automated control systems, computer network systems and network communication technologies. To measure the success of an intelligent system in a residential community does not only depend on the number of intelligent systems, the advanced nature or integration of the system, but on whether the design and configuration of the system are economical and reasonable and whether the system can operate successfully. Whether it is convenient to use, manage and maintain, and whether the system or product technology is mature and applicable, in other words, how to exchange the least investment and the easiest way to achieve maximum efficiency and achieve convenient and high-quality life.

In order to achieve the above goals, the following principles should be followed when designing a smart home system:

Practical convenience

The most 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 practicality as the core, abandoning those flashy functions that can only be used as decorations, and the products are mainly practical, easy-to-use and user-friendly.

We believe that when designing a smart home system, the following most practical and basic home control functions should be integrated according to the needs of users for smart home functions: including smart home appliance control, smart lighting control, electric curtain control, anti-theft alarm, access control intercom, Gas leaks, etc., while also expanding service value-added functions such as three-meter copying and video-on-demand. Personalization for many

Smart home control methods are rich and diverse, such as: local control, remote control, centralized control, mobile phone remote control, sensor control, network control, timing control, etc. The original intention is to let people get rid of tedious tasks and improve efficiency. The process and program settings are too cumbersome, and it is easy for users to have a feeling of rejection. Therefore, when designing a smart home, you must fully consider the user experience, pay attention to the convenience and intuitiveness of the operation, and it is best to use a graphical control interface to make the operation what you see is what you get.


The intelligent subsystems of the entire 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 of the system, good quality and performance, and the ability to cope with various complex environmental changes.


The design of the smart home system solution should be carried out in accordance with relevant national and regional standards to ensure the scalability and expansibility of the system. The standard TCP/IP protocol network technology is used for system transmission to ensure that the systems between different manufacturers can be compatible and interconnected. . The front-end equipment of the system is a multifunctional, open, and expandable equipment. For example, the system host, terminal and module adopt standardized interface design to provide an integrated platform for external manufacturers of home intelligent systems, and its functions can be expanded. When additional functions are needed, there is no need to excavate the pipe network, which is simple, reliable, and convenient. The design and selection of systems and products can enable this system to be interconnected with third-party controlled equipment that will continue to develop in the future.


Whether the wiring installation is simple is directly related to the cost, scalability, and maintainability issues. You must choose a simple wiring system, which can be wired together with the community broadband during construction. It is simple and easy; the equipment is easy to learn and master, and easy to operate and maintain. .

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

A significant feature of home intelligence is that the workload of installation, commissioning and maintenance is very large, requiring a large amount of manpower and material resources, which has become a bottleneck restricting the development of the industry. In response to this problem, the convenience of installation and maintenance should be considered when the system is designed. For example, the system can be debugged and maintained remotely via the Internet. Through the network, not only allows residents to realize the control function of the home intelligent system, but also allows engineers to remotely check the working status of the system and diagnose the faults in the system. In this way, system settings and version updates can be performed in different places, which greatly facilitates the application and maintenance of the system, improves response speed, and reduces maintenance costs.

Data security

In the gradual expansion of smart homes, more and more devices will be connected to the system, which will inevitably generate more operating data, such as air-conditioning temperature and clock data, indoor window opening and closing status data, gas meter data, etc. . These data have an unprecedented degree of association with the privacy of individual families. If data protection is caused inadvertently, it 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 the state of windows, which will directly endanger family safety. . At the same time, the smart home system is not isolated from the world, and the data that enters the system must be reviewed to prevent malicious damage to the home system, or even the networked appliances and equipment. Especially in the era of big data, we must prevent the security of big data at home.
