A blockchain-based pollution traceability and early warning method and system for the whole process of lead and zinc ore dressing

Abstract

The present invention discloses a blockchain-based pollution traceability and early warning method for the whole process of lead and zinc beneficiation, comprising the following steps: data collection and uploading: real-time collection of environmental parameter data through the IoT sensor nodes deployed in each key link of the whole process of lead and zinc beneficiation, encrypting and signing said data, broadcasting it to the blockchain network, and generating a new block packaged by the consensus mechanism after verification, to accomplish the data deposit. By deeply integrating blockchain technology with specific environmental protection scenarios of lead and zinc beneficiation, the present invention realizes a complete closed loop from credible data deposit to intelligent warning and then to accurate traceability, using the non-tamperability of the blockchain to improve the credibility of the data, the intelligent contract to execute the warning to make the warning faster and more intelligent, and the complete and credible data chain, which has a high supervisory efficiency, a high degree of traceability accuracy and can be securely and credibly for sharing and breaking information silos.
