What is the architecture and main divisions of the Internet of Things?

The architecture of the Internet of Things is mainly divided into: 1. Perception layer, the bottom layer of the Internet of Things; 2. Network layer, responsible for data transmission and communication; 3. Platform layer, providing the core functions of the Internet of Things system; 4. The application layer is the top layer of the Internet of Things, which provides specific applications and services based on the functions and data of the platform layer.

The architecture of the Internet of Things (IoT) is mainly divided into the following levels:

1. Perception Layer: The perception layer is the core of the Internet of Things The bottom layer is used to collect and perceive real-world data. It includes various sensors, actuators and devices, such as temperature sensors, humidity sensors, cameras, etc. These devices can convert the collected data into digital signals and transmit them to the upper layer through the network.

2. Network Layer: The network layer is responsible for data transmission and communication. It includes network facilities such as sensor networks, local area networks, wide area networks, and the Internet. At the network layer, data is passed to intermediate nodes for routing and data forwarding to ensure that the data can be passed from the perception layer to the application layer.

3. Platform Layer: The platform layer provides the core functions of the Internet of Things system, including data storage, data processing, equipment management, and service management. At the platform layer, data is received, stored and processed, as well as managed and controlled accordingly. These functions can be realized through cloud platforms, edge computing, etc.

4. Application Layer: The application layer is the top layer of the Internet of Things. It provides specific applications and services based on the functions and data of the platform layer. These applications and services can involve various fields, such as smart homes, smart cities, industrial control, etc. The application layer can realize the optimization and application of the Internet of Things system through data analysis, human-computer interaction and decision support.

In addition to the above-mentioned layer division, there are also some key horizontal technologies and components, such as security and privacy protection, data standardization, protocols and communications, etc., which run through the entire IoT architecture. Ensure system security, interoperability and scalability.

It should be noted that the architecture of the Internet of Things can change according to different application scenarios and requirements. The above-mentioned hierarchical structure is just a common way of division. In actual applications, the specific IoT architecture may be customized and expanded according to different needs.
