Abstract
How to realize the safe and efficient use of power terminal equipment data is a key research content to enhance the value of smart grid data. In order to solve this problem, based on the master-slave blockchain theory, this paper designs an intelligent terminal data management system architecture based on the master-slave blockchain. The architecture includes three modules: master blockchain, slave blockchain, and system service interface. In order to improve the security of data in the process of data use, this paper conducts research from the two dimensions of data security storage and data access control, and proposes a data security storage mechanism and a data access control mechanism. In order to improve the efficiency of data query when the amount of data is large, this paper adopts the grouping bloom filtering strategy and the B+ tree index strategy to reduce the number of data queries and improve the efficiency of data query. In the experimental part, from the performance analysis of the improved Bloom filter based on grouping and the performance analysis of the block query mechanism based on the B+ tree index, it is verified that the data usage mechanism proposed in this paper has high block creation and data query efficiency.
