Chapter 1: Introduction
The Internet of Things is an emerging technology field. By connecting physical devices, sensors and software, the interconnection and intercommunication between devices can be realized, so that various devices can exchange data and intelligently control them. In this digital age, the Internet of Things has become one of the key technologies to connect everything, and is widely used in smart homes, smart industries, smart cities and other fields.
This article will introduce the architecture and technology of the Internet of Things, and discuss how to realize the Internet of Things and intelligent control.
Chapter 2: IoT Architecture
The IoT architecture refers to the organizational structure and relationship among various devices, networks, and platforms in the IoT system. The IoT architecture is mainly composed of three layers, namely the perception layer, the network layer and the application layer.
The perception layer is the lowest layer in the IoT system, responsible for the physical devices and sensors that perceive the surrounding environment. These devices can sense various data, such as temperature, humidity, light, etc., and transmit the data to the network layer for processing and storage.
The network layer is the middle layer in the IoT system, responsible for data transmission and processing. At this layer, various devices can exchange data through different communication protocols, such as Wi-Fi, Bluetooth, NFC, etc.
The application layer is the uppermost layer in the IoT system, responsible for data processing and application. At this layer, users can realize intelligent control of devices through various applications, such as smart home control, smart factory control, etc.
