Air pollution data processing system based on blockchain technology

Abstract

The invention provides an air pollution data processing system based on blockchain technology, which comprises a data transponder, a data acquisition system and a data verification platform composed of a plurality of data verification nodes, wherein the data acquisition system is used for monitoring air pollution, obtaining air pollution concentration data and transmitting the data to the data transponder; after receiving the processed air pollution concentration data, the data transponder forwards the data to the data verification platform; a plurality of data verification nodes in the data verification platform are responsible for verifying and saving the air pollution concentration data forwarded by the data transponder; each data verification node is a blockchain node, and a pluralityof the data verification nodes form a distributed database; the air pollution data processing system based on blockchain technology further comprises a data processing center, and the data processingcenter is used for sequentially performing pre-processing, clustering processing, and abnormality detection processing on the verified air pollution concentration data, and marking the detected abnormal air pollution concentration data and storing data into the database.

Description

Technical field [0001] The invention relates to the technical field of air monitoring, in particular to an air pollution data processing system based on blockchain technology. Background technique [0002] Among the related technologies, the methods for monitoring urban air pollution mainly include: [0003] (1) The traditional method, that is, the method of manual sampling laboratory analysis. This method can only obtain the monitoring values ​​within a certain period of time in the air pollution monitoring area, and cannot perform real-time monitoring. The monitoring results are greatly affected by humans. At the same time, when the concentration of harmful gases in the air pollution monitoring area is high, it will seriously damage the monitoring. Physical health of personnel; [0004] (2) At present, the more popular online monitoring uses imported automated air environment monitoring equipment for monitoring. Although this monitoring method can achieve real-time monitoring, th...

[0003] (1) The traditional method, that is, the method of manual sampling laboratory analysis

This method can only obtain the monitoring value within a certain period of time in the air pollution monitoring area, and cannot perform real-time monitoring. The monitoring results are greatly affected by human beings. the physical health of personnel;

[0004] (2) The current popular online monitoring mostly uses imported automatic air environment monitoring equipment for monitoring. Although this monitoring method can achieve real-time monitoring, the equipment used is complex in structure, expensive, difficult to maintain, and has high operating costs. Its working environment is harsh

In the data collection link, illegal nodes can impersonate or attack legitimate nodes to upload illegal sensing data; Modifications, which eventually lead to illegal uploaded data, etc.
