1. Perception layer: The perception layer is the lowest layer of the Internet of Things system and is mainly responsible for information collection and data generation. This layer contains various sensors, RFID tags, bar codes and other devices, which are used to collect various physical and environmental information. The role of perception layer is equivalent to human senses, which can perceive and collect external information.
2. Network layer: The network layer is the middle layer of the Internet of Things system, which is mainly responsible for information transmission and data processing. This layer contains various network devices and communication protocols, such as Wi-Fi, Bluetooth, ZigBee, etc. Which is used to transmit the data collected by the perception layer to the application layer. The function of network layer is equivalent to human neural network, which can transmit the information collected by perception layer to application layer for processing.
3. Application layer: The application layer is the top layer of the Internet of Things system, which is mainly responsible for information processing and application. This layer contains various applications and services, such as smart home, smart manufacturing, smart medical care and so on. Used to process and apply the transmitted data. The application layer is equivalent to the human brain, which can make corresponding decisions and controls according to the information transmitted by the perception layer.
4. The three levels of the Internet of Things system cooperate with each other to realize information exchange and intelligent processing between objects. Through this system, people can obtain and manage all kinds of information more conveniently and improve production efficiency and quality of life.
Functions of Internet of Things System
1. data collection and monitoring: IOT devices can collect a large amount of data, including environmental data (such as temperature, humidity, illumination, etc. ) and equipment operation data. These data can be monitored and analyzed in real time through the Internet of Things system, which can help people to better understand and master the running status of equipment and environmental changes, so as to make more effective decisions.
2. Intelligent management: The Internet of Things system can realize intelligent management, that is, through automatic identification, tracking, positioning and management of equipment and articles, the management efficiency and quality can be improved. For example, in the field of logistics, the Internet of Things technology can help enterprises to monitor the location and status of goods in real time and improve the efficiency and accuracy of logistics.
3. Predictive maintenance: Through the Internet of Things system, enterprises can monitor the running status of equipment in real time, predict the maintenance requirements of equipment, and carry out maintenance and overhaul in time to avoid equipment damage or production interruption. This kind of predictive maintenance can reduce the failure rate and maintenance cost of equipment, and improve the production efficiency and service life of equipment.
4. Optimize resource allocation: The Internet of Things system can help enterprises understand the operating conditions and requirements of equipment, timely adjust production plans and resource allocation, optimize resource allocation, and improve production efficiency and product quality.
5. Innovative business model: The application of Internet of Things technology can bring new business models and innovative opportunities for enterprises. For example, through the internet of things technology, enterprises can realize remote monitoring and management of equipment and provide more efficient and convenient services; At the same time, the Internet of Things technology can also be combined with e-commerce, smart home and other fields to innovate business models and improve the competitiveness of enterprises.
