Internet of Things development

In November 2000, the International Telecommunication Union (ITU) issued a report entitled "ITU Internet reports 2005-the Internet of Things", which formally presented the Internet of things (the things, IoT) term. [7], which has aroused widespread concern around the world. The IoT integrates a variety of sensing, communication and computing technologies to make communication between people (Human to Human, h2h) easier, and to make people and things (Human to Things, h2t), Things and Things (Thing to Thing, T2T), the communication between the human society, the information space and the physical world (human-machine-object) will eventually be integrated into one. [8] Therefore, the internet of Things is considered the third wave of the world's information industry, following the computer and the Web.

Traditional control system Monitoring PC software generally runs on the computer end, the field monitoring personnel need to be fixed in the central monitoring room for viewing operations, to the staff has brought greater inconvenience. At the same time in the traditional industrial field equipment maintenance and commissioning generally need to use walkie-talkie to achieve the field operators and central control room communication and information exchange, which improves the equipment maintenance inspection difficulty [9].

The core of the Internet of things is that things are connected in a variety of ways, such as WiFi, GPR/CDMA, Bluetooth, infrared, RFID, NFC, visual recognition, voice recognition, and so on, this article uses mobile NFC to identify external device identification, and then use WiFi to communicate with the device, using the Internet and server interaction , so it is a concrete embodiment of IoT applications.
