What is the highest level of the Internet of Things technology architecture?

The top layer of the Internet of Things technology architecture is the application layer; the application layer is at the top of the three-layer architecture of the Internet of Things. The application layer provides a wealth of Internet of Things applications based on Internet of Things technology, and has different application results for different industries. , realizing the intelligent application of the Internet of Things in different industries is the fundamental goal of the Internet of Things technology.

The top layer of the Internet of Things technology architecture is the application layer

Three-layer architecture of the Internet of Things

With the development of social economy Continuously progressing, the progress of the Internet of Things era has received a lot of attention.

The Internet of Things uses information sensing equipment to connect objects to the Internet in wired or wireless ways in accordance with agreed protocols to communicate or obtain information, in order to realize the intelligentization of the connection of things and the interconnection of all things. A network that identifies, locates, tracks, monitors, and manages.

The Internet of Things has a three-layer basic architecture, namely the perception layer, the network layer, and the application layer.

Perception layer

The perception layer is located at the bottom of the three-layer architecture of the Internet of Things. It senses and collects the environment through related sensing devices. The information and perception layer is the foundation and core layer of the Internet of Things and a key part of information collection.

The perception layer generally includes sensor technology, radio frequency identification technology, QR code technology, Bluetooth technology, and ZigBee technology. To put it simply, humans perceive the external environment through touch, vision, etc. to judge environmental information. The perception layer is like the tentacles of the Internet of Things, used to identify external objects and collect information, and then use the related technologies mentioned above to transmit data. .

Network layer

The network layer is mainly responsible for transmitting and processing the data information passed by the perception layer , perform relevant processing and then transmit it to the application layer. The network layer is the middle layer of the three-layer architecture of the Internet of Things and the layer with the highest degree of standardization. The network layer includes the Internet, wired/wireless communication networks, network management systems, and cloud computing platforms.

Application layer

The application layer is at the top of the three-layer architecture of the Internet of Things. It provides a wealth of Internet of Things applications based on Internet of Things technology, and is suitable for different Different industries have different application results. Realizing the intelligent application of IoT in different industries is the fundamental goal of IoT technology. For example: smart agriculture, smart home, smart transportation, smart water, etc., the application layer is an object-oriented service architecture.

The perception layer, network layer, and application layer are the three keys to the Internet of Things, and each one is indispensable. This three-layer architecture realizes the exchange of information between all items, the mutual understanding of objects, and completes intelligent identification and management.
