With the development of the economy, people's demand for modern high-quality life is growing. Under this background, smart home as a representative of quality life has naturally become a popular object and an inevitable trend of future family life. The more people come in to grab a cup!
Smart home technology analysis
Smart home, also known as smart home. In layman's terms, it is a networked intelligent home control system that integrates automatic control system, computer network system and network communication technology. Smart homes will give users more convenient means to manage home devices, such as controlling home devices through home touch screens, wireless remote controls, telephones, the Internet, or voice recognition, and can perform scene operations to link multiple devices; In terms, various devices in the smart home can communicate with each other, and can operate interactively according to different states without user command, thereby bringing maximum efficiency, convenience, comfort and safety to the user.
Smart home integration integrates equipment related to home life by using integrated wiring technology, network communication technology, security technology, automatic control technology, and audio and video technology.
Due to the different technical standards and protocols adopted by smart homes, most smart home systems use integrated wiring, but a few systems may not use integrated wiring technologies, such as power carriers. In either case, there must be a corresponding network. Communication technology to accomplish the required signal transmission tasks, so network communication technology is one of the key technologies in smart home integration.
Security technology is an indispensable technology in smart home systems. It is widely used in community and indoor video intercom, home monitoring, home burglar alarm, and family-related community card.
Automatic control technology is an indispensable technology in smart home systems. It is widely used in intelligent home control center and intelligent home host home equipment automatic control module. It plays an important role in the scientific management of home energy and the schedule management of home equipment. . Audio and video technology is an important technology to achieve the comfort and artistry of the home environment. It is reflected in the centralized distribution of audio and video, background music, home theater and so on.
Smart home purchase knowledge
The first thing to remember is a truth: "The best for you is the best!"
First, smart homes are divided into two types: wired and wireless.
1. Wired, or bus type. In this way, all control devices must be connected to the controller through wired. The signal line of the controller terminal will be scary. If there is a problem, it will be checked if the identification is unclear. Difficulties, and high wiring costs, inconvenient maintenance, and inconvenient modification are also its shortcomings.
Of course, this is not to say that wired is useless. If the pipeline is reserved at the beginning of the new house design, many problems can be avoided, and its super stable performance is also an advantage that the wireless type can never surpass.
So if customers like super-stable performance and don't mind wired, then wired type can still be considered! And even if it is a wireless wireless home system, it is not exactly like they say that there is no need to lay a line, many places Still have to be wired, such as power lines, audio lines, etc. No smart home brand dare to say that it does not need wiring at all.
2. The other type is wireless. The wireless transmission method is nothing more than infrared, Bluetooth, wifi, radio frequency, Zigbee, power carrier, etc. Each transmission method has its advantages and disadvantages:
Infrared is the most commonly used and most economical short-distance wireless transmission method. Infrared control is used for TVs, DVD players, air conditioners, etc., but infrared devices are received in a straight line, and the transmitter must be facing the receiving device. It can't be turned or penetrated, but it doesn't matter. It can be solved by infrared forwarding line or infrared transponder. Its most deadly drawback is that many times its signal is negated, you can't know its state, you can't know its true state when you control it remotely, this problem can't be solved yet!
Bluetooth is also a radio technology that supports short-range communication (typically within 10m) of devices, enabling wireless information exchange between devices including mobile phones, PDAs, wireless headsets, notebook computers and other related peripherals. But this is only a point-to-point short-range communication, and the power consumption is higher. In smart home applications, it can only be used as an auxiliary method to transmit things like music on mobile phones, and it can't be used.
WIFI is a short-range wireless transmission technology that supports radio signals for Internet access within a few hundred meters. Its biggest feature is that it is convenient for people to access the Internet anytime and anywhere. In the smart home, the network camera, UPNP device and all wireless control are all realized through it, so Wifi is the most important transmission method. Of course, its networking expertise is relatively strong, and power consumption is relatively high, which is also a major drawback.
With the development of the times, the consumption level of people is gradually increasing. At the same time, people's entertainment methods are beginning to diversify, especially for modern young people. As a result, different kinds of electronic products are starting to be in people's lives, and the booming Electronic Cigarette industry reflects this.
Described including the upper shell, the upper shell at the top of the smoke outlet, as described in the bottom of the upper shell with airway, described with the smoke outlet in the airway and also to match the upper shell, the lower part of the shell described the airway in the direction of the lower shell extension, as described in the lower shell near one end of the upper shell is equipped with oil mouth, described the lower shell with batteries, described at the bottom of the bottom shell has come in The air port is provided with an oil storage bin in the lower shell, and the air passage passes through the oil storage bin and is provided with a heating atomization bin at one end away from the smoke outlet. The utility model has beneficial effects: it can meet the smoking habit of different users, avoid the premature end of the use experience caused by excessive consumption of smoke oil, and indirectly prolong the service time and life of the product.
