Design of Fishery Germplasm Resource Management System Based on Blockchain
Aiming at the problems of data center storage,data tampering and data trust in traditional fishery germplasm resource management system,as well as the difficulty in efficient acquisition and utilization of multi-source heterogeneous fishery disease data,based on the analysis of key technologies of blockchain and knowledge graph,the structure of fishery germplasm confirmation and trusted traceability block was designed to ensure the unforgeability and security of fishery germplasm traceability data.The collaborative management and storage strategy of'On-Chain+Off-Chain'fishery germplasm resources credible confirmation information is proposed to solve the problems of high data storage pressure and low query efficiency of each node in the fishery germplasm resources traceability blockchain network.The fishery disease knowledge graph is constructed to realize effective mining of hidden relationship of fishery disease data.Based on micro-service technology,a fishery germplasm resource management system integrating germplasm confirmation,variety selection,disease prevention and control,knowledge map and environmental intelligent prediction was developed to realize the functions of credible confirmation and management of fishery germplasm resources,intelligent analysis and decision-making of fishery breeding varieties,integration and sharing of massive heterogeneous fishery disease knowledge resource pools,intelligent prediction and early warning of environmental parameters(dissolved oxygen concentration,pH,etc.).The test results show that the system solves the problem of authenticity and credibility of traceability information,effectively excavates the hidden relationship in fishery disease data,and achieves good application results.
