The Research of CPS System Driven by Blockchain

Abstract

The CPS system senses and recognizes the physical world through numerous node devices and processes the collected data accordingly, then it can achieve the interconnection of the physical world and the virtual network world. However, under the existing conditions, the CPS system has not yet realized the interconnection between nodes and nodes and the physical world. Block chain technology is a distributed ledger in which nodes can freely enter and exit. This article proposes to combine the block chain with the CPS system to improve the efficiency and security of the CPS system. Through theoretical analysis and experiments, it is proved that the combination of block chain and CPS system can effectively improve the scalability of CPS system and improve the ability of CPS system to communicate with the physical world. Through the combination of the public chain and private chain of the block chain, the production speed of the block is improved, and the actual demand of the CPS system is better satisfied.
