The components of the Internet of Things include: 1. Perception and identification layer; 2. Network construction layer; 3. Platform management layer; 4. Comprehensive application layer. The perception layer is the foundation of the overall architecture of the Internet of Things, and the network layer plays a connecting role in the entire Internet architecture.
The Internet of Things can be roughly divided into four levels: perception layer, network layer, platform layer and application layer.
The details are as follows:
1. Perception and identification layer
The perception layer is the foundation of the overall architecture of the Internet of Things and an important part of the integration of the physical world and the information world. At the perception layer, we can sense the object itself and the surrounding information through sensors, so that the object also has the ability to "speak and release information", such as sound sensors, pressure sensors, light intensity sensors, etc. The perception layer is responsible for collecting and obtaining information for the Internet of Things.
2. Network construction layer
The network layer plays a connecting role in the entire IoT architecture. It is responsible for transmitting sensing information to the upper layer and transmitting commands to the lower layer. The network layer transmits the information collected by the perception layer to the IoT cloud platform, and is also responsible for transmitting the instructions issued by the IoT cloud platform to the application layer, which serves as a link. The network layer mainly transmits massive information through the Internet of Things, the Internet, and mobile communication networks.
3. Platform management layer
The platform layer is the core of the overall architecture of the Internet of Things. It mainly solves issues such as how to store, retrieve, and use data, as well as data security and privacy protection. The platform management layer is responsible for effectively integrating and utilizing the information collected by the perception layer through big data, cloud computing and other technologies, and providing scientific and effective guidance for people to apply it to specific fields.
4. Comprehensive application layer
The Internet of Things will eventually be applied to various industries. After the information transmitted by objects is processed by the IoT Cloud Platform, the valuable information unearthed will be Apply it to real life and work, such as smart logistics, smart medical care, food safety, smart parks, etc.
