Also known as Smart housing, commonly used in foreign countries to indicate Smart Home. Similar to the meaning of smart home system are home automation, electronic home, digital home, home network, network home, smart home/building, in Hong Kong and Taiwan and other regions, there are digital home, digital home and other names.
Roots
Since the world’s first intelligent building appeared in the United States in 1984, the United States, Canada, Europe, Australia and Southeast Asia and other economically developed countries have put forward a variety of smart home programs. The Singapore model of home intelligent system includes three table CC function, security alarm function, visual intercom function, monitoring center function, home appliance control function, cable TV access, household information message function, home intelligent control panel, intelligent wiring box, broadband network access and system software configuration.
Standard
In 1988, the Electronic Industry Association of the United States prepared the first electrical design standard applicable to the home, that is, the Home Automation System and Communication Standard, also known as the Home bus system standard (HBS); In the beginning of 1997, we began to formulate the “Well-off Residential Electrical Design (Standard) Guidelines” (discussion draft). In the Guidelines, it is stipulated that the electrical design of well-off residential areas should meet the following requirements on the whole: high security, comfortable living environment, convenient means of communication, comprehensive information service, family intelligent system. At the same time, it also puts forward three levels of design standards for the construction of well-off houses and communities in the aspects of security prevention, automation of family equipment, communication and network configuration, namely: the first level is the “ideal target”, the second level is the “universal target”, the third level is the “minimum target”.

You can easily upgrade your home to a smart home even after your home has been renovated. Wireless control of smart home system can not destroy the original decoration, as long as some sockets and other places to install the corresponding module can realize intelligent control, not to cause damage to the original house wall.
Principles of Design
Smart home is also known as smart residence. Generally speaking, it is the integration of automation control system, computer network system and network communication technology in one of the networked intelligent home control system. Measuring the success of an intelligent system in a residential community does not only depend on the number of intelligent systems, the advanced or integrated degree of the system, but also depends on whether the design and configuration of the system is economical and reasonable and whether the system can be successfully operated, whether the use, management and maintenance of the system is convenient, and whether the technology of the system or the product is mature and applicable. In other words, Is how to use the least investment, the most convenient way to achieve the greatest effect, to achieve a convenient and high-quality life.
In order to achieve the above goals, the smart home system design should follow the following principles:
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 be practical as the core, to abandon those flashy, can only be used as decoration functions, products to practicability, ease of use and humanization.
We believe that in the design of 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: intelligent home appliance control, intelligent lighting control, electric curtain control, anti-theft alarm, access intercom, gas leakage and so on. At the same time, it can also expand such as three table CC, video on demand and other value-added service functions. For a lot of personalization
Smart home control mode is very rich and diverse, such as: local control, remote control, centralized control, mobile phone remote control, induction control, network control, timing control and so on, its intention is to let people get rid of the tedious business, improve efficiency, if the operation process and program Settings are too tedious, easy to let users have the rejection psychology. Therefore, in the design of smart home must take full account of user experience, pay attention to the facilitation and intuitive operation, it is best to use the graphical control interface, so that the operation of what you see is what you get.
Reliability
All the intelligent subsystems of the whole building should be able to operate around the clock, and the safety, reliability and fault tolerance of the system must be attached great importance. For each subsystem, appropriate fault tolerance measures are taken in terms of power supply and system backup to ensure the normal and safe use, good quality and performance of the system, and the ability to cope with various complex environmental changes.
Quality of standard
The design of smart home system scheme should be carried out in accordance with the relevant national and regional standards to ensure the scalability and expansibility of the system. Standard TCP/IP protocol network technology is adopted in the system transmission to ensure that the system can be compatible and interconnected 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 to provide an integrated platform for the external manufacturers of the home intelligent system, and its functions can be expanded. When it needs to add functions, there is no need to excavate the pipe network, which is simple, reliable, convenient and economical. The system and product selected in the design can interconnect the system with the third party controlled equipment which is developing continuously in the future.
Convenience of use
Whether the wiring installation is simple or not is directly related to the cost, scalability, maintainability of the problem, must choose the wiring system is simple, construction can be connected with the community broadband wiring, simple and easy; The equipment is easy to learn, operate and maintain.
The convenient design of the system in the engineering installation and commissioning is also very important.
Home intelligence has a remarkable characteristic, is the installation, debugging and maintenance workload is very large, need a lot of manpower and material resources investment, become the bottleneck restricting the development of the industry. To solve this problem, the convenience of installation and maintenance should be considered in the design of the system. For example, the system can be debugged and maintained remotely through the Internet. Through the network, not only enables the residents to realize the control function of the home intelligent system, but also allows the engineers to check the working condition of the system remotely and diagnose the faults of the system. In this way, the system setting and version update 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
In the gradual expansion of smart home, there will be more and more equipment connected to the system, it is inevitable to produce more operating data, such as air conditioning temperature and clock data, indoor window switch status data, gas meter data and so on. These data and personal family privacy form an unprecedented degree of correlation, if the data protection is careless, not only will lead to personal habits and other extremely private data leakage, in relation to family security data, such as window state data leakage will directly harm the family security. At the same time, the smart home system is not isolated from the world, but also to review the data entering the system to prevent malicious damage to the home system, even damage to the Internet appliances and equipment. Especially in today’s era of big data, we must protect the security of family big data.
The choose and buy
There are many smart home brands in the domestic market, and there is no unified technical specification. The products of various domestic and international brands have their own characteristics and advantages and disadvantages. It is often difficult for buyers to make a horizontal comparison when choosing smart home products.
Is the system stable?
System stability is the first consideration when purchasing. The installation of smart home is to bring convenience, safety and comfort to life. If an intelligent system fails to meet the stability requirements and some large and small problems appear from time to time, then it will only bring the user trouble and enjoy the smart home will be out of the question. The stability of the smart home system mainly includes the stability of the product of the sub-control module, the stability of the system operation, the stability of the line 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 on the stability, basically you can be assured to choose.
2. Are the functions integrated?
Smart home is a centralized and unified control of household devices. The core products include communication protocols, system platforms or operating systems, and configuration solutions for the field environment. The corresponding specific products include security equipment, lighting control equipment, multimedia equipment, environmental control equipment, etc. These devices will be concentrated in this system, through the communication protocol of the system, so that each subsystem is connected to each other, information interchange, operation can control each other. If each subsystem is independent operation of the product without centralized control, users will be quite troublesome to use, is not called smart home system. Many manufacturers on the market advertise one or several simple subsystem products as smart home, so in addition to understanding the component functions of each subsystem, more should be asked in detail about the integration performance of the whole system.
3. Is the system concise?
If the smart home system is selected, the corresponding consideration must be made in the stage of house decoration and design, and the installation of home wiring at the same time. To achieve the same function, the simpler the system needs to be configured, which means that the overall system is more integrated and has higher technology content. The so-called “simplicity” includes the number of modules needed to achieve the same function, the capacity limits of the entire system, the number of devices controlled by the module, and the simplicity of the wiring and other aspects of the problem. It can be said that the system is simple or not can comprehensively reflect the integration of smart home products, durability, beauty, as well as the design strength of the manufacturer.
4. Is the system applicable?
Regardless of the brand of smart home products, the key is to fit your needs. The more modules used in the whole system, the higher the complexity, the more expensive the price, the higher the possibility of failure in the future, and the corresponding high maintenance costs. Therefore, we should firmly start from our own needs, consider the use frequency of various functions in the future, and appropriately simplify some flashy functions, which will substantially save costs. In addition, it is necessary to consider whether the system control interface is friendly, and the difference between different users’ habits. In this way, the smart home system can really play a role and provide convenience for users’ life.
5. How scalable is the system?
Smart home is still a new product, the technology used by different manufacturers is different, lack of uniform standards. Moreover, the development speed of relevant technologies is very rapid, and the existing technologies can be said to be transitional technologies. Therefore, it is recommended that users choose products with good compatibility and adopt international general protocols. Relatively mature international general protocols include LonWorks, X-10, etc.
6. How self-protective is the system?
Smart home system under malicious attack or request key data transmission will take what kind of processing method, the system in what form to protect the security of the system (some home systems will try to shut down the system, but there are some devices can not stop running, such as electricity meters), to connect to the network of equipment upstream and downstream data supervision degree, reduce the system data scattering.
Composition
The smart home system consists of eight main subsystems: home wiring system, home network system, smart home (central) control and management system, home lighting control system, home security system, background music system (such as TVC flat panel sound), home theater and multimedia system, home environment control system and so on. 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 environment control system for optional systems.
In the identification of smart home system products, the smart home (smart home system products) produced by manufacturers must belong to the necessary system, can realize the main functions of smart home, can be called smart home. Therefore, smart home (central) control management system (including data security management system), home lighting control system, home security system can be directly referred to as smart home (smart home system products). And the optional system can not be directly called smart home, can only use the combination of smart home and specific system expression method, such as background music system, known as smart home background music. It is misleading for users to call alternative system products as smart home directly.
In the identification of smart home environment, only the complete installation of all the necessary systems, and at least one optional system installed at least one or more smart home can be called smart home.
