Problems solved by technology
However, according to statistics, by 2020, each person will generate an average of 1.5GB of data per day. As more and more devices are connected to the Internet and generate data, the cloud may not be able to fully process and store the data in the cloud. Especially in some usage scenarios that need to process data quickly, the data is transmitted to the cloud computing and then returned to the terminal. The limitation of transmission distance may lead to the failure of real-time data

The present invention relates to data storage technology, in particular to a lightweight data management system and method for edge nodes in power systems. The system includes access control subsystems, storage subsystems, backup and recovery subsystems, search encryption subsystems, and privacy protection Subsystems, lock subsystems, pool subsystems, log subsystems, deduplication subsystems, and encryption subsystems; the present invention is aimed at the prior art power system, where the edge node storage space is limited, but the calculation speed is fast, and the storage space is limited. How to efficiently store data at edge nodes provides a method of storing data in a 64MB Flash memory, solving the problem of centralized storage and calculation of a large amount of physical data in the current power system, consuming a large amount of network bandwidth and computing resources, and causing network congestion troubled.
Description
technical field [0001] The invention relates to data storage technology, in particular to a lightweight data management system and method for edge nodes in power systems. Background technique [0002] Traditional centralized data processing is to upload data to the cloud through the network for unified storage, analysis and calculation. Cloud storage works together through cluster applications, network technology or distributed file systems or similar network computing functions, and through certain Application software or application interface provides users with certain types of storage services and access services. However, according to statistics, by 2020, each person will generate an average of 1.5GB of data per day. As more and more devices are connected to the Internet and generate data, the cloud may not be able to fully process and store the data in the cloud. Especially in some usage scenarios that need to process data quickly, the data is transmitted to the cloud...
