Application of NFC technology in the field of smart home

With the continuous development of NFC technology, many mobile devices such as smartphones, cameras, and tablet computers can support NFC functions. At present, this technology has even begun to extend to the field of smart homes, such as smart refrigerators, smart washing machines, and smart air conditioners. Experience and promote the comprehensive intelligence of smart home.

Use of smart home

It is understood that at the 2014CES conference, LG, Hisense and other companies applied NFC technology to smart white goods. Users can use wireless signals to control home appliances through mobile terminals with NFC functions within a certain range, so as to realize human-machine control. In the future, it can also form interconnection and mutual control with home smart devices such as electronic tags, sensing systems, and personal health care equipment.

In addition, according to industry data surveys, the global NFC smartphone shipments in 2012 were about 100 million units, with a penetration rate of about 18%. The penetration rate data is expected to reach 30% and 50% in the next two years. In addition, there is news recently that the iPhone 6 built-in NFC technology may be settled this year.

So what exactly is NFC technology? NFC technology evolved from non-contact radio frequency identification. It is a short-range high-frequency radio technology jointly developed by Philips Semiconductors (now NXP Semiconductors), Nokia, and Sony. Near-field wireless communication between devices, consumer electronics, PCs and smart control Tools provides a simple, touch-based solution that allows consumers to exchange information and access content and services simply and intuitively.

As a new short-distance wireless communication technology, NFC technology has unique security advantages, fast connection, and low cost. Using NFC technology, the smart home system greatly improves the response speed and simplifies the tedious steps quickly. With a flick of your phone, you can easily handle all the programs. And it can control smart home based on NFC mobile phone. The principle is mainly that the smart home device is wirelessly connected to the mobile phone with NFC card reader through the Zigbee module, and the card reader in the mobile phone exchanges data with the NFC smart card to obtain the previous preset. There are a variety of functional data, so that the smart home device can be controlled through the wireless network to perform related operations.

Through the above smart home operating system based on NFC technology, it is easier and more convenient to realize intelligent home life. For example, in the early morning, the owner is in a hurry to go to work. When he goes out, he “swipes” the door lock with his mobile phone. Within 1-2 seconds, the doors and windows are closed, the electrical appliances and lights in the house are turned off, and the smart security function starts to activate; When you are eating, put your mobile phone on the table, the wall lamp will be turned off, and the chandelier will be turned on; after dinner, just use your mobile phone to "wave" towards the TV, and the chandelier will be turned off immediately, the wall lamp will be turned on, the TV will play, and moving music will come out of the room.

With the promotion of wireless technologies such as Zigbee, z-wave, etc., wireless smart homes have the characteristics of free wiring, easy installation, and scalability, which greatly reduce the cost of smart home implementation. NFC technology is widely used in smart devices to realize things. The interactive communication between them further simplifies the operation mode and improves the smart home control experience. I believe that in the future, more devices with NFC technology will be launched to enhance the interaction between devices and simplify people's lives.
