Scientific research data management control system and method based on block chain technology

Abstract

The invention belongs to the technical field of scientific research data management. The invention discloses a scientific research data management control system and method based on a block chain technology. The scientific research data management control system based on the blockchain technology comprises a scientific research data acquisition module, a data splitting and cleaning module, a datacalibration module, a data statistics module, a data classification module, a data feature extraction module, a data analysis module, a data block chain construction module, a block index module, a web crawler management module, a data storage module and a display module. By means of the block index module, operation resources and time can be saved and the scientific research data block index updating efficiency is improved; after the block is packaged, the block head information of the block is broadcasted to the block chain network through the block chain storage module, and the content of the whole block is not broadcasted, so that the broadcast content is reduced, and the network transmission pressure is reduced; and the block information is stored by using the distributed storage network, so that the storage pressure of a single node is reduced.

Description

Technical field [0001] The invention belongs to the technical field of scientific research data management, and in particular relates to a scientific research data management control system and method based on blockchain technology. Background technique [0002] At present, scientific research refers to a series of activities such as investigations, experiments, and trial productions conducted to understand the inner nature and movement laws of objective things using scientific research methods and equipment to provide theoretical basis for the creation of new products and new technologies. The basic task of scientific research is to explore and understand the unknown. Data is something that exists in the CYBER space; information is a phenomenon that exists and occurs in nature, human society and human thinking activities; knowledge is the knowledge and experience that people obtain in practice. Data can be used as a symbolic representation or carrier of information and knowledg...

Problems solved by technology

[0003] To sum up, the problems and defects of the existing technology are: when the scientific research data block index scheme in the existing scientific research data management control system and method based on blockchain technology constructs a multi-party index table, every time a scientific research data is added It is necessary to recalculate the index table including all scientific research data blocks when data blocks, which will not only cause a waste of computing resources in the scientific research data block chain, but also cause low transaction efficiency; at the same time, as the amount of scientific research data continues to increase, The amount of scientific research data that needs to be processed per unit time increases, and the amount of scientific research data contained in a single block also needs to increase, resulting in an increase in the size of a single block, thereby increasing the pressure on network transmission
