Guidelines for Electrical Design (Standard) of Well-off Residential Buildings (discussion draft). In the "Guidelines", it is stipulated that the electrical design of well-off residential quarters should generally meet the following requirements: high security, comfortable living environment, convenient communication methods, comprehensive information services, and family intelligent systems. At the same time, it also proposes three-level design standards for the construction of well-off houses and communities in terms of safety precautions, home equipment automation, and communication and network configuration, namely: the first level is the "ideal goal", the second level is the "popularization goal", and the third level is the "ideal goal". Level 3 is the "minimum target".
On March 10, 1999, Bill Gates, chairman of Microsoft Corporation, announced the "Venus Project" in Shenzhen. This is a solution for digital home appliances tailored to China's information industry and home appliance market. The goal is to develop a new product based on Microsoft's Windows CE operating system that integrates computing, entertainment, education, communication, communication and web surfing.

4. The role of smart home systems
A smart home system is a kind of living environment for people. It uses a house as a platform to install a smart home system to achieve safer, energy-saving, intelligent, convenient and comfortable home life. Taking the residence as a platform, using integrated wiring technology, network communication technology, smart home-system design scheme security technology, automatic control technology, audio and video technology to integrate the facilities related to home life, and build efficient management of residential facilities and family schedule affairs The system improves home safety, convenience, comfort, artistry, and realizes an environment-friendly and energy-saving living environment.
Smart home systems make it easy for you to enjoy life. When you are away from home, you can remotely control various smart systems in your home by phone and computer, for example, turn on the air conditioner and water heater in advance on the way home; when you arrive at home, the system will automatically turn on the aisle lights with the help of the door sensor or infrared sensor. , at the same time open the electronic door lock, disarm the security, turn on the lighting lamps and curtains at home to welcome your return; when you return home, you can use the remote control to conveniently control various electrical equipment in the room, and you can select presets through the intelligent lighting system The lighting scene, creating a comfortable and quiet study in the study; creating a romantic lighting atmosphere 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 home, such as pulling the curtains and pouring water into the bathtub. And automatically heat and adjust the water temperature, adjust the status of curtains, lights, and sound; the kitchen is equipped with a video phone, you can make calls or check the visitors at the door while cooking; when you work in the company, you can also display the situation at home. You can check it at any time on the computer or mobile phone in the office; the door machine has the function of taking pictures and taking pictures.
5. Features of Smart Home System
5.1 Random lighting
Control random lighting controls, adjust the lighting in all rooms with a few button presses, and create all kinds of dream lights as you like! The intelligent lighting system has a soft-start function, which can make the light gradually brighter and darker; the light dimming can realize the function of brightening and dimming, allowing you and your family to share warmth and romance, and at the same time, it has the effect of energy saving and environmental protection; the full on and full off function can be used. It can easily realize one-key full-off and one-key full-on functions of lights and appliances, and has a brightness memory function.
5.2 Simple installation
Smart home systems can be easily installed without destroying partition walls or purchasing new electrical equipment, and the system can be fully connected to your existing electrical equipment in your home, such as lamps, telephones, and appliances. Various electrical appliances and other intelligent subsystems can be controlled at home or fully controlled remotely.
The smart home system is an expandable system. Initially, your smart home system can only be connected with lighting equipment or common electrical equipment, and can also be connected with other devices in the future to meet the needs of new smart life.
Even your home can be easily upgraded to a smart home even if it has been renovated. The wireless control smart home system can not destroy the original decoration, as long as the corresponding modules are installed in some sockets, etc., the intelligent control can be realized, and it will not cause damage to the original house wall.
5.4 Design Principles
Smart home is also called smart home. In layman's terms, it is a networked and intelligent home control system that integrates automation control system, computer network system and network communication technology. To measure the success of an intelligent system in a residential area, it is not only determined by the number of intelligent systems, the advanced nature of the system or the degree of integration, but also depends 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 technology of the system or product is mature and applicable, in other words, how to exchange the maximum effect with the least investment and the easiest way to realize a convenient and high-quality life.
In order to achieve the above goals, the following principles should be followed when designing a smart home system:
5.4.1 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 to focus on practicality, get rid of those flashy functions that can only be used as decorations, and focus on practicality, ease of use and humanization.
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 leakage, etc., at the same time, it can also expand service value-added functions such as three-meter copy and video on demand. to a lot of personalization
The control methods of smart home are very 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. The process and program settings are too cumbersome, and it is easy to make users feel repulsive. Therefore, when designing a smart home, we must fully consider the user experience, pay attention to the convenience and intuitiveness of operation, and it is best to use a graphical and graphical control interface, so that what you see is what you get.
All 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 scheme should be carried out in accordance with the relevant national and regional standards to ensure the scalability and scalability of the system. The standard TCP/IP protocol network technology is used in the system transmission to ensure that the systems between different manufacturers can be compatible and interconnected. . The front-end equipment of the system is a multi-functional, open and extensible equipment. For example, the system host, terminal and module adopt standardized interface design, which provides an integrated platform for external manufacturers of the smart home system, and its functions can be extended. The systems and products selected for the design enable the interoperability and interconnection of this system with future third-party controlled devices that are evolving.
Whether the wiring installation is simple or not is directly related to the issues of cost, scalability and maintainability. It is necessary to choose a system with simple wiring. It can be wired together with the residential broadband during construction, which is simple and easy; the equipment is easy to learn and master, and it is easy to operate and maintain. .
The convenient design of the system in engineering installation and debugging is also very important.
A significant feature of home intelligence is that the workload of installation, commissioning and maintenance is very large, requiring a lot of human and material resources, which has become a bottleneck restricting the development of the industry. In response to this problem, when designing the system, the convenience of installation and maintenance should be considered. For example, the system can be remotely debugged and maintained through the Internet. Through the network, it not only enables the residents to realize the control function of the home intelligent system, but also allows the engineers to check the working status of the system remotely and diagnose the faults of 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 the response speed, and reduces maintenance costs.
5.5 Data Security
In the gradual expansion of smart homes, more and more devices will be connected to the system, and more operating data will inevitably be generated, such as air conditioner temperature and clock data, indoor window switch status data, gas meter data, etc. . These data have an unprecedented degree of association with the privacy of individual families. If data protection is inadvertent, it will not only lead to extremely private data leakage such as personal habits, but also data leakage related to family security, such as window status, will directly endanger family security. . At the same time, the smart home system is not isolated from the world, and the data entering the system must be reviewed to prevent malicious damage to the home system, and even damage to networked appliances and devices. Especially in today's big data era, we must protect the security of family big data.
6. Purchase of smart home system
There are many smart home brands in the domestic market, and there is no unified technical specification. The products of various domestic brands and international brands have their own characteristics and advantages and disadvantages. When purchasing smart home products, it is often difficult for buyers to compare horizontally. Therefore, a comprehensive investigation should be carried out from multiple aspects and angles, and the following points can be grasped:
6.1 Is the system stable?
The stability of the system is the first factor to consider when purchasing. The purpose of installing a smart home is to bring convenience, safety and comfort to life. If a smart system fails to meet the requirements in terms of stability, and some big and small problems occur from time to time, it will only bring users trouble and enjoyment. Smart home will be out of the question. The stability of the smart home system mainly includes the product stability of the sub-control module, the stability of the system operation, the stability of the circuit structure, the stability of the integrated function, the stability of the running time, etc. If a set of smart home products can meet these requirements in terms of stability. Basically, you can choose it with confidence.
6.2 Is the function integrated?
Smart home is the centralized and unified control of home equipment. The core of the product includes communication protocols, system platforms or operating systems, and configuration solutions for on-site environments. The corresponding specific products include security equipment, lighting control equipment, multimedia equipment, environmental control equipment, etc. These devices will be concentrated on this system, through the communication protocol of the system, the various subsystems will be connected to each other, the information can be exchanged, and the operation can be controlled with each other. If each subsystem is a product that runs independently and lacks centralized control, it will be quite troublesome for users to use, and it cannot be called a smart home system. Many manufacturers on the market promote one or several simple subsystem products as smart homes, so in addition to understanding the component functions of each subsystem, you should inquire about the integration performance of the entire system in detail.
6.3 Is the system simple?
If you choose a smart home system, you must consider it in the design stage of house decoration, and install it at the same time as the home wiring. In order to achieve the same function, the simpler the system needs to be configured, the higher the integration of the entire system and the higher the technical content. The so-called "simple" includes the number of modules required to achieve the same function, the capacity limit of the entire system, the number of devices controlled by the module, and the simplicity of wiring. It can be said that whether the system is simple or not can comprehensively reflect the integration, durability and aesthetics of smart home products, as well as the design strength of manufacturers.
6.4 Is the system suitable?
No matter what brand of smart home products, the key is to suit your needs. The more modules used in the entire system, the higher the complexity, the more expensive the price, the higher the probability of failure in the future, and the higher the corresponding maintenance cost. Therefore, you should firmly start from your own needs, consider the frequency of use of various functions in the future, and properly simplify some flashy functions, which will greatly save costs. In addition, when purchasing, it is necessary to consider whether the system control interface is friendly, as well as the differences in the usage habits of different users. In this way, the smart home system can really play a role and provide convenience for the user's life.
6.5 How scalable is the system?
Smart home is still an emerging product, and the technologies used by various manufacturers are different, and there is a lack of unified specifications. Moreover, the development speed of related technologies is very rapid, and the existing technologies can still be regarded as transitional technologies. Therefore, it is recommended that users choose products with good compatibility and adopt international general protocols. The more mature international general protocols include LonWorks, X-10, etc.
6.6 How self-protection is the system?
What kind of processing method will the smart home system take when it is maliciously attacked or requesting the external transmission of key data, and what form does the system take to protect the security of the system (some home systems will try to shut down the system, but some devices cannot stop running, Such as electricity meters), supervise the level of upstream and downstream data of devices connected to the network, and reduce the amount of system data scattered.
7. The composition of the smart home system
The main subsystems included in the smart home system are: home wiring system, home network system, smart home (central) control management system, home lighting control system, home security system, background music system (such as TVC flat panel audio), home theater and multimedia system, home environment control system and other eight systems. Among them, smart home (central) control management system (including data security management system), home lighting control system, home security system are essential systems, home wiring system, home network system, background music system, home theater and multimedia system, home An environmental control system is optional.
In the identification of smart home system products, the smart home (smart home system product) produced by the manufacturer must be an essential system and can realize the main functions of the smart home before it can be called a smart home. Therefore, smart home (central) control management system (including data security management system), home lighting control system, home security system can be directly called smart home (smart home system products). The optional systems cannot be directly called smart home, but can only be expressed by a combination of smart home and specific systems, such as a background music system, called smart home background music. Calling optional system products directly as smart homes is misleading to users.
In the identification of a smart home environment, only a smart home that has installed all the necessary systems and at least one or more optional systems can be called a smart home.
7.1 Wiring system
