Smart home is also called smart house. Generally speaking, it is a networked smart home control system integrating automation control system, computer network system and network communication technology.
In fact, since the smart home entered China at the end of last century, the industry has developed for more than ten years. It has changed from a boring term into various security systems, intercom systems, automatic meter reading systems, fire alarm systems, home theater systems, lighting and home appliance control systems, home information platforms, information home appliances and so on. It seems that the market is gradually maturing, but it seems that it has not yet developed to a certain scale, and it seems to be behind closed doors. In fact, there are many problems that hinder the whole industry.
At present, the problems existing in the smart home market are: lack of standardized and unified industry standards; Industrial core technology needs to be broken through; The application mode needs to be innovated, and the stability and reliability of products need to be further improved; The industrial chain is incomplete and lacks a perfect social cooperation system; Cross-industry cooperation is difficult; The marketing is not strong enough. This is also an urgent task to be broken through in the "Twelfth Five-Year" development plan of smart home in the future.
Now, the Internet of Things has brought a second life to smart homes. According to Li Li, deputy director of the Science and Technology Department of the Ministry of Industry and Information Technology, the 12th Five-Year Development Plan of the Internet of Things led by the Ministry of Industry and Information Technology will be issued. The Ministry of Industry and Information Technology will support application demonstration projects in key areas, including intelligent industry, intelligent agriculture, intelligent logistics, intelligent transportation, smart grid, intelligent environmental protection, intelligent security, intelligent medical care, smart home and other nine areas, especially smart home, intelligent medical care and other areas that benefit people's livelihood and improve people's quality of life. The potential application demand is more urgent, so it is expected to form a larger industrial scale.
Stimulated by the trend of triple play, active policy guidance, human-computer interaction and Internet of Things technology, major manufacturers are gearing up to compete for this big cake in the field of smart home.
Through the smart home technology of the Internet of Things, a home network system can be set up, so that multiple computers can surf the Internet with a broadband line, saving costs and realizing functions such as resource sharing and online games among computers. You can also set up a home control network to control the actions of information-based household appliances (such as air conditioners, refrigerators, microwave ovens, washing machines, water heaters) and other intelligent devices (such as curtains, locks, lights, etc.). ). You can also set up a home monitoring network to monitor and control home safety through home monitoring equipment, and even see home images through the Internet in the office and have a conversation with people at home. You can also set up a home video network, use a video recorder (VCD/DVD/ computer) to play programs for multiple TV sets to watch, and transmit movies on the broadband network to TV sets to watch. There are also home audio networks that send audio signals to all rooms for listening, and MP3 music on computers or networks can also be sent to stereos for playing. The most important thing is that you can set up a safety alarm system. If someone breaks into the room illegally, or there are dangerous situations such as gas leakage and fire, the system will send an alarm signal by SMS, MMS, telephone and so on at the first time; In the afternoon, the weather suddenly changed, and it rained heavily. You can use your mobile phone to close the window remotely, so you don't have to face the dilemma of "flooding Jinshan" as soon as you get home …
The smart home of the Internet of Things not only brings us convenience and brand-new experience, but also has a great impact on energy consumption, urban transportation, intelligent environmental protection and so on, and is even considered by foreign experts as a market that affects the whole body. With the rapid development and in-depth application of Internet of Things and smart home technology, smart home system is developing towards networking, informationization and intelligence, which will usher in rare development opportunities for manufacturers in smart home industry.
Second:
Digital intelligent community system consists of intelligent terminal equipment, access control machine, management center machine and other supporting equipment. Through TCP/IP networking and standard RJ-45 communication interface, all devices can be connected through a network cable, and then all data can be exchanged through a common network switch, thus realizing the digital application of the system, and connecting well with lighting, curtain, alarm, household appliances, monitoring, audio-visual and other systems. It is a smart home system with rich functions. Support smart home functions such as access control management, home security, audio and video recording, video monitoring, residential MMS, remote reading of three meters, home appliance control, lighting control, electrical appliance control, remote control, etc.
For personalized intelligent applications, some manufacturers have also developed wireless intelligent terminals, which are similar in appearance to NS-A7-G66 and black in shell.
Support WiFi wireless transmission mode, which is divided into master and slave. There is a power socket connection between the master terminal and the bracket, which is convenient for charging its built-in battery, ensuring that the equipment is always in an uninterrupted state and automatically enters the power-saving mode when it is not used for a long time; The extension controls the keyboard through keys, which is about the size of the TV remote control and easy to operate. The wireless intelligent terminal has also designed a handheld remote control device, which is only the size of a mobile phone. Built-in smart home control functions such as lighting, security, home appliances, cinemas and music. With self-study function, it is extremely convenient to carry and operate indoors.
There are many types of smart home system hosts to choose from, such as NS-A5-C 10 door machine, which adopts a lens with a 92-degree viewing angle and has the functions of backlight compensation and infrared compensation. The minimum illumination is 0. 1Lux, which can provide a clear image of 420TVL. Adopt aluminum alloy panel, which has standard anti-strike ability, and can be fixed by embedded wall or iron gate; The standby power is 0.8W, and it can be equipped with a maximum 5-inch display screen. It has the function of advertising, supporting the functions of contactless IC/ID card access control and credit card authentication, password unlocking, patrol punching, door closing and tamper detection. Under the digital protocol (TCP/IP), a single host can carry 9999×9 intelligent terminals with huge capacity, which can meet the unified application of super-large intelligent buildings.
The intelligent terminals of some smart home systems adopt Linux operating system, full Chinese interface menu, and support touch operation. When in standby, the screen automatically turns black to enter the power saving mode (you can also set the clock and standby screen, etc.). ), the tester can tap with his finger to enter a fast and rich terminal interface, and display the current time, date, room number and other information at the bottom of the system interface in real time. The main menu is located at the top of the interface, with options such as shortcut menu, visual intercom, community information, home intelligence, home assistant and system settings. And the menu box is slightly larger than the finger, which increases the touch. Then tap "Home Intelligence" with your finger to enter the smart home control options. On the Scene menu, click Welcome mode. At this time, the system will enter the set welcome mode: air conditioning, lighting, curtains will automatically open, and the audio-visual system will automatically stand by; When the "out-of-home" mode is selected, the smart home system will automatically turn off curtains, lights, household appliances, etc. According to the set procedure, everything will be convenient.
Smart home will provide users with more convenient means to manage household equipment, such as controlling household equipment through home touch screen, wireless remote control, telephone, internet or voice recognition, and performing scene operation to make multiple devices form linkage; On the other hand, various devices in smart home can communicate with each other and operate interactively according to different states, without user's command, thus bringing maximum efficiency, convenience, comfort and safety to users.
