Drone Data Monitoring Based On Blockchain And IPFS And Storage System Design

In recent years,as a new field,UAV is widely used in military and civil fields because of its low cost and diverse functions.However,with the frequent occurrence of UAV "black flight" events,the social security and public safety of the people are seriously threatened.The resulting supervision of UAV and the storage of flight data have attracted much attention.In view of the above problems,according to the blockchain technology,this paper introduces the key technology of IPFS,takes low cost,high efficiency,secure storage and sharing as the starting point,abandons the traditional centralized storage mode,and selects the distributed storage scheme.On this basis,using the method of blockchain + IPFS,Monitor the flight trajectory of UAV and efficiently store a large amount of data generated in the flight process of UAV.As a shared database,the data stored in the blockchain has the characteristics of "unforgeability","whole process trace","openness and transparency","collective maintenance" and "traceability",which strengthens the foundation of trust and creates a mechanism of cooperation.IPFS is a global peer-to-peer distributed hypermedia publishing protocol,which integrates the best distributed storage idea in the current publishing system and provides a globally unified addressable space for everyone.IPFS technology not only meets the requirements of huge data storage in this paper,but also ensures the safety performance of data storage.At the same time,according to the different system architecture and user needs,this topic designs seven core service functions.In the process of UAV flight,the system can effectively implement the functions of data storage and real-time trajectory monitoring,and finally provide services to users through PC terminal and mobile terminal.Based on blockchain and IPFS,taking Hyperledger fabric as the underlying technology chain,this paper uses IPFS to store the original data,build the underlying system,and analyze the market demand for the system.In order to facilitate users to monitor the UAV in real time,this paper also compiles a web display interface,which can find the "black flying phenomenon" in time,keep the "black flying" records permanently,and effectively pursue the responsibility of illegal personnel.After the internal test of the system,the network based on blockchain and IPFS built in this paper runs stably,which can ensure the storage and monitoring of UAV data within a certain range,and ensure the authenticity,stability,responsibility and integrity of data storage,and realize the real-time monitoring of UAV trajectory.This paper studies the application of blockchain technology and IPFs technology in the field of UAV data storage and supervision,and provides technical support for the application of blockchain technology and IPFS distributed storage technology in the machinery industry.
