A data monitoring and automatic control method for smart agriculture based on a double-chain mechanism

Abstract

The invention discloses a smart agricultural data monitoring and automatic control method based on a double-chain mechanism. The edge server of the agricultural participating department serves as a full node of the blockchain to jointly store and maintain two blockchains, the main chain and the side chain. The main chain stores perception data certificates, smart contract sets for data indexing and verification, and the side chain stores analysis results and smart contract sets for implementing various automatic controls in agriculture. The architecture uses smart contract technology to realize the automatic control of smart agriculture; through off-chain storage and on-chain verification, the integrity and authenticity of perceived data is guaranteed, and the overhead of blockchain data storage is reduced; the dual-chain mechanism is used to further improve system performance.

Description

technical field [0001] The invention relates to the field of agricultural information technology, in particular to an agricultural data monitoring and automatic control method based on a double-chain mechanism. Background technique [0002] With the development of modern technology, a new generation of information technology has gradually appeared on the stage of agricultural development, and the traditional agricultural development mechanism has ushered in a new development opportunity. The intervention of Internet of Things technology has made the development of smart agriculture take shape, which has improved the overall production efficiency of agriculture and promoted the process of agricultural modernization. The Agricultural Internet of Things is a combination of traditional agriculture and the Internet of Things technology. It senses real-time data in the process of smart planting through various advanced instruments, analyzes these data through the Internet of Thing...

Problems solved by technology

[0003] However, the current agricultural planting control method based on the Internet of Things relies on a highly centralized data management architecture. In this architecture, the data is centralized and thus lacks transparency. Its security and integrity cannot be guaranteed, and even related data may be tampered with. lost

In addition, the existing control methods for agricultural planting instruments mainly adopt centralized operation and management. At the same time, if the control program is maliciously tampered with on the central platform, it cannot be effectively supervised.

These will lead to misoperation of agricultural instruments, resulting in huge agricultural production and economic losses

[0004] However, the current blockchain-based agricultural control applications mainly write agricultural perception data directly into the blockchain. Since the blockchain belongs to distributed ledger technology, all participating nodes need to store all the perception data, which will greatly increase the area. Storage overhead of blockchain participating nodes

In addition, the existing methods mainly write application data (such as control programs, control parameters, etc.) and perception data into the same blockchain, but when using the corresponding data, it is necessary to search from a large amount of block data. This can cause long delays for data applications
