Blockchain-based Carbon Emission/Energy Consumption Data Management and Operation System and Method of Enterprises

A blockchain-based data management and operation method for carbon emission/energy consumption of enterprises, which is characterized in that the method comprises:

• S1, the enterprise port collects and sends operation data to the data center control, wherein the operation data include water consumption data, electricity consumption data, coal consumption data, gas consumption data, heat consumption data, output value data and equipment data of the enterprise;
• S2, the data center control substitutes the operation data into the intelligent production accounting model to obtain enterprise-level production indicators, accumulates all the enterprise-level production indicators in the region to obtain regional production indicators, and substitutes the regional production indicators into the prediction algorithm to obtain regional prediction data, wherein the production indicators comprise carbon emission indicators, energy consumption indicators and economic indicators;
• S3, the data center control is pre-set with regional target data, and determines whether the regional prediction data exceeds the target data, and if so, obtains the regional energy consumption reduction task and the regional carbon emission reduction task according to the difference between the regional production data and the regional prediction data;
• S4, the data center control calculates the enterprise-level energy consumption reduction potential value and the enterprise-level carbon emission reduction potential value according to the enterprise-level production indicators and the regional production indicators, allocates the regional energy consumption reduction task and the regional carbon emission reduction task based on the two potential values to obtain the enterprise-level assessment indicators, and sends the enterprise-level assessment indicators to the corresponding enterprise port, and the regional production indicators, regional prediction data, regional energy consumption reduction tasks, regional carbon emission reduction tasks and enterprise-level assessment indicators to the regional data display port;
• S5, the enterprise port visually displays the enterprise-level operation data and the enterprise-level assessment indicators, and the regional data display port visually displays regional production indicators, regional prediction data, regional energy reduction tasks, regional carbon reduction tasks and enterprise-level assessment indicators;
• S6, the data center control determines whether the enterprise production indicators have the corresponding enterprise assessment indicators, if so, whether the former are higher than the latter, and if so, it determines that the enterprise has won the policy reward;
• S7, the data center control is set with a new energy equipment database, from which the new energy equipment data are retrieved based on the operation data and production indicators. The new energy equipment database is a collection of new energy equipment data, including the model, quantity and price of new energy equipment, and the data are submitted to the data center control through supplier ports;
• S8, an energy saving and emission reduction report is generated based on the operation data, production indicators and new energy equipment data, and sent to the enterprise ports. In the report, new energy equipment data, input amount, configuration capacity, configuration scale of new energy equipment, annual energy saving value after new energy equipment input, annual carbon reduction value after new energy equipment input, energy consumption ratio before and after new energy equipment input, carbon emission ratio before and after new energy equipment input, return ratio of new energy equipment input, prediction annual return rate after new energy equipment input, and return cycle after new energy equipment input are included;
• S9, enterprise port visually displays the energy saving and emission reduction report;
• S2 specifically comprises the following sub-steps:
• S21, compiling the production calculation formula into a production calculation formula in the form of intelligent contract code, wherein the production calculation formula comprises a carbon emission calculation formula, an energy consumption calculation formula and an economic calculation formula, and the carbon emission calculation formula is:
• Etotal=Σin(NCVi×FCi×CCi×OFi×44/12)+(ΣETDm+EWD)+(ADelectricity×EFelectricity)+(ADheat×0.11)
• In which, Etotal refers to the total greenhouse gas emissions of an enterprise, i refers to the types of fossil fuels, NCVi refers to the average low calorific value of the type i fossil fuels, FCi refers to the net consumption of the type i fossil fuels, CCi refers to the unit heat value carbon content of the type i fossil fuels, OFi refers to the carbon oxidation rate of the type i fossil fuels, m refers to the types of greenhouse gases, ETDm refers to the leakage of the type i greenhouse gas, ADelectricity refers to the net purchased electricity of the enterprise, EFelectricity refers to the annual average emission factor of the power grid in the region, and ADheat refers to the net purchased heat of the enterprise;
• S22, compiling the production calculation formula in the form of intelligent contract code into the intelligent contract to obtain an intelligent production accounting model, which contains a signature, a timestamp and a Hash function;
• S23:
• substituting the operation data into the intelligent production accounting model to calculate the enterprise-level production indicators, which will be uploaded to the blockchain network;
• the blockchain network comprises blockchain nodes, and the blockchain nodes comprise enterprise ports, data center control and regional data display port.
