Data Management System Based On Agricultural Internet Of Things

In recent years,the application of Internet of Things in the agricultural field has been increasing.Internet of Things data is divided into structured data collected by conventional sensors and unstructured data collected by cameras and other equipment.How to store heterogeneous agricultural Internet of Things data with high performance and ensure the security of data storage with certain strategies is the current key issue of agricultural Io T data management.In order to solve the storage problem of heterogeneous data in the Internet of Things,this paper proposes a hybrid technology storage scheme.For structured data storage,this paper designs a structured data storage scheme based on My SQL distributed database and Redis cache;for unstructured data such as pictures,it is managed through the Fast DFS distributed file system,and the Redis cache is used to store the index mapping of the file relationship and realize the function of fast reading hot data.On this basis,this paper combines technologies such as load balancing to further improve storage read and write performance.To improve the security of system data storage,this paper proposes a data security management strategy,and designs an integrated data virtual mapping space to manage agricultural Internet of Things data from different sources.The space is split into several sub-spaces,and improve the data scrambling rules to scramble the data,and finally realize the security management of data in the agricultural Internet of Things by establishing a hierarchical hybrid encryption mechanism.Then combined with the storage scheme and security strategy proposed in this paper,the current mainstream technical scheme is studied,and the detailed implementation scheme of the data management system based on the agricultural Internet of Things is given.Finally,a test environment was built to test the functions and performance of the system.The test results show that the solution in this paper has a better functional experience and performance,which improves a set of feasible and reliable solutions for the data storage and management of the agricultural Internet of Things.At present,this system has been put into use in a group company in Jiangsu,and has achieved good results.
