With the development of science and technology and the improvement of people's living standards, intelligent buildings are no longer just a concept, but a development trend in the construction industry. Intelligent buildings include smart buildings and smart homes. The development of smart homes in China has started slightly later than developed countries such as the United States and Europe. Smart home not only has the traditional living function, but more importantly, it provides people with a safe and comfortable family living space. Smart homes provide people with a full range of information exchange functions through high-tech (intelligent systems), helping families and the outside to maintain information exchange, not only for people to effectively arrange time, enhance the safety of home life, but also save various Energy costs.
A smart home system includes home security system, home integrated wiring system, intelligent lighting system, home intelligent integrated system, home automation control system, home entertainment system and so on. Among them, intelligent integrated systems and automated control systems are the core, they control and manage other systems through the home integrated wiring system.
In recent years, smart homes have also developed rapidly in China. More and more homes are beginning to introduce intelligent systems and equipment, and the content covered by intelligent systems is also developing from a simple way to a combination of multiple ways. Because China's smart home system started a little later, the current mainstream products in the market can not solve the contradiction between the product itself and the market demand, so it has greatly hindered the development of the smart home industry.
The future development of smart home is mainly based on the new technology based on multiple fields, constantly making up and improving the shortcomings and shortcomings of the current smart home system, making the smart home system more perfect and more powerful, further improving the comfort of smart home. And security. Therefore, only by fully understanding the characteristics of the current mainstream smart home system on the market, can we correctly analyze and predict the development trend of the future smart home system.
Let's talk about the characteristics of the current mainstream smart home system.
1. The intelligent terminal serves as the main control and management platform for the smart home system. Most of the intelligent terminals use embedded systems. Most of them use the ARM plus DSP combination chip as the core CPU of the control terminal. The system often uses the Linux operating system. Under such circumstances, the intelligent terminal acts as the control and management core of the system, and the system is separated from it. Can not operate normally, each functional terminal must be under the control and management of the intelligent terminal to run. In the current smart home market, the touch screen is the most commonly used smart terminal, and the function of the system depends on the function of the touch screen. However, the flexibility of this method is not good enough. The structure of the system determines that the system can only be configured with other control subsystems of the original manufacturer, such as home alarm system, building intercom system, access control system, etc. Some manufacturers use their own dedicated bus. And interfaces, so the system will be more difficult to expand.
2. The control logic and management functions of the smart home system have been determined before leaving the factory. As a control product, its function, control method, and management ability of the system are determined in advance by the manufacturer. If the manufacturer does not adequately analyze the user requirements of the system, it is difficult to come up with a product that truly meets the user's needs. The products are not destined to last long in the market.
3. Multi-screen control is difficult in smart home systems, and control objects need to be bundled beforehand. For villas, it is often necessary to have multiple control terminals. Such a system structure is often difficult to connect to multiple intelligent control terminals, because it is impossible to have multiple control centers and management centers in one system, which will appear in the control logic. The chaos of control. At the same time, since the system is determined in advance by the manufacturer, its control object has been bound in advance, such as the number of zones for alarms, the number of circuits for lighting control, the number of channels for dimming control, etc. These control objects need to be bound, and the user wants If you make changes based on your own usage, you will most likely be limited by the system.
Because of the above characteristics of intelligent terminals, to a large extent, it has not fully matched the actual needs of the current market. Therefore, there is an urgent need to be able to make up for the shortcomings of the current intelligent system while fully utilizing the intelligence. Advantages of the system and platform. The smart home interactive platform is in line with this demand.
So what kind of system does the smart home need in the future?
First, the functionality of a smart home system can change as people's lives change. The lifestyle and life needs of a family are constantly changing with the development of society. The smart home system should also change with the changes in the needs of the residents. Usually, the most direct change in household demand is reflected in the changes in the front-end equipment. Therefore, in the future, only the home system should be able to adapt to various changes, such as changes in equipment brands, functional changes, changes in control logic, and changes in operating habits.
Secondly, the smart home system should adopt a modular design, and each subsystem can operate independently from the interactive platform. Under the management of the smart home system platform, subsystems such as building intercom system, home alarm system, access control system and home entertainment system can realize their own functions and realize the linkage of the system. The biggest benefit of this modular design is that it is easy to maintain and upgrade. A subsystem has problems or needs to be upgraded, it will not affect other systems, and it will save money during maintenance and upgrade process and protect consumers' investment.
Third, the hardware systems and software systems used in smart home systems should conform to international standards, with maximum compatibility, and users have greater choice. The system should be compatible with all major brands of products, mainstream control protocols and different system bus and control interfaces. In addition to compatible with a variety of mainstream control buses and interfaces, such as RS485, RS232, USB, IEEE1394, etc., can also expand the popular control bus and interface at home and abroad, such as EIB, lonwork, CE-bus, Canbus, and wireless networks, such as WiFi, GPRS, 3G, Bluetooth, etc. In other words, it is necessary to continuously increase the various bus and system driver software, software and hardware interfaces, and a variety of communication control interfaces according to changes in users and the market, providing the basis and guarantee for the diverse selection of subsystems. In addition, the system can be connected to the LAN of the property management on the one hand, and can be connected to the WAN on the other hand to achieve remote control and remote management.
Fourth, the smart home system truly realizes “intelligence†and can automatically optimize the control system. When the system platform is established, most control systems can be selected by the user. In other words, the smart home system is an open system, users can configure their own smart home system according to their own needs, which requires the system to have "automatic learning" according to the user's lifestyle and living habits. Features. Such a home system is based on the hardware of various intelligent terminals, and there is a strong database management system behind the software system. The intelligent terminal (the touch screen mentioned above) is only used as the display and operation interface of each subsystem, and is no longer the center of control and management.
Fifth, the smart home system users are easy to use and can configure the control system according to their living habits and lifestyle. Users can design their own personalized interface, which can make the system a member of the family, in harmony with the atmosphere of the home.
Sixth, smart home systems can be controlled by a variety of means. In daily home life, we need to control the home system at any time and get access to home information at any time. The form of operating the terminal is very important. The future smart home system can be controlled by various forms of intelligent terminals, such as smart remote control, mobile touch screen, computer, mobile phone, PDA and so on.
Of course, the future development trend of smart home systems is not limited to the above six points. It will continue to change with the advancement of science and technology and the renewal of people's concepts. However, no matter how it develops, it is to improve the comfort and safety of people's family life, and ultimately achieve the harmonious unity between man and nature.
