With the rapid development of science and technology, the Internet of Things came into being. Industrial Internet of Things (Internet of Things, IoT) is simply a network between things. It is based on the Internet and connects things intelligently through radio frequency identification technology (RFID), sensor technology, wireless network communication technology and cloud computing technology On the Internet, real-time tracking and updating of items are carried out through the Internet to realize automatic identification of information. The Industrial Internet of Things mainly uses various controllers with perception and monitoring capabilities, and technologies such as mobile communications, information processing, and intelligent analysis to obtain relevant information in all aspects of industrial production. For sales and other aspects, remote monitoring, resource monitoring and security maintenance are managed.
The establishment of an efficient and low-cost industrial Internet of Things is a key link in building an intelligent manufacturing network infrastructure. In the traditional networking mode, the communication between all devices must be achieved through a centralized proxy communication mode, and the connection between the devices must be through the network, which greatly increases the networking cost, and at the same time is scalable, maintainable and stable. Poor sex.
Blockchain technology uses P2P networking technology and hybrid communication protocols to handle the communication between heterogeneous devices. Rules can be pre-embedded through smart contracts to transform each smart device into an independent network node that can be self-maintained, and other nodes The exchange of information or identity verification prolongs the service life of the equipment and saves a lot of equipment maintenance costs.
At the same time, computing and storage requirements can be distributed to the various devices that make up the network, effectively preventing any single node in the network from failing and causing the entire network to collapse.
In addition, the anti-tampering feature of the distributed ledger in the blockchain effectively prevents any single-node device in the industrial Internet of Things from being maliciously attacked and controlled, and the risk of information leakage and malicious manipulation is aimed at data loss during transmission. Circumstances such as leakage, theft, etc., provide a highly reliable data transmission channel for the Industrial Internet of Things, thereby realizing secure communication between devices. Finally, the use of blockchain technology to build and manage the industry, multiple nodes synchronize data in real time, can timely and dynamically grasp the status of various manufacturing equipment in the network, improve equipment utilization and maintenance efficiency, and provide accurate and efficient Supply chain financial services.
