[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Example 1

[0042] See also Figure 1 As shown, the present invention is a carbon emission and carbon footprint measurement system for industrial enterprises based on power big data, including the following modules:

[0043] Calculation module: Set the calculation period to calculate the carbon footprint of all equipment in the enterprise. 总Process and calculate the current carbon footprint value of the enterprise;

[0044] In some implementation schemes, the current equipment power consumption data of the enterprise is obtained and the formula , calculate the carbon footprint E of each device in the enterprise 总 ;

[0045] In the formula, A represents the electricity consumed in production, AE i and EF i They represent the quantity of the raw materials produced and the carbon emission factor of the raw materials respectively;

[0046] Set the calculation period to obtain the carbon footprint E of all equipment in the enterprise during the calculation period. 总 , and sum them up to get the current carbon footprint value of the enterprise;

[0047] Measurement module: Build a carbon footprint model for each device, analyze and obtain the carbon footprint exceeding standard assessment value of the equipment in the enterprise, and then compare it with the corresponding threshold to identify the exceeding equipment;

[0048] In some embodiments, the analysis period is set to calculate the time period as the X-axis and the carbon footprint E 总 As the Y axis, a carbon footprint model is constructed, and the carbon footprint E obtained during the analysis period is 总 Substitute it into the model and draw a curve to obtain the equipment carbon footprint curve; and in the carbon footprint model, set a carbon footprint standard line parallel to the X-axis (the value of the carbon footprint standard line is pre-set by the technicians according to the industry standard);

[0049] Analyze the equipment carbon footprint curve and the carbon footprint standard line to obtain the excess quantity ratio and the excess time ratio, and calculate the excess quantity ratio and the excess time ratio to obtain the carbon footprint excess assessment value;

[0050] Compare and judge the carbon footprint excess assessment value with the carbon footprint excess assessment threshold;

[0051] If the carbon footprint excess assessment value is greater than or equal to the carbon footprint excess assessment threshold, it means that the carbon footprint standard of the enterprise's equipment exceeds the standard during the carbon footprint calculation and measurement process, which has a great impact on the company's carbon footprint indicators and is marked as an excess equipment;

[0052] If the carbon footprint excess assessment value is less than the carbon footprint excess assessment threshold, it means that the carbon footprint standard of the equipment in the enterprise does not exceed the standard during the carbon footprint calculation and measurement process, and has little impact on the enterprise's carbon footprint indicators, and it is marked as non-exceeding equipment;

[0053] First, specifically, the analysis process of the superscalar ratio is:

[0054] Obtain each carbon footprint curve of the equipment located above the carbon footprint standard line, record it as an analysis curve segment, obtain the area enclosed by each analysis curve segment and the carbon footprint standard line, and mark it as an excess value;

[0055] All the excess values ​​in the analysis period are summed up to obtain the excess scalar value;

[0056] Then the excess value is calculated by comparing it with the total carbon footprint value to obtain the excess ratio;

[0057] Among them, the total carbon footprint value is the total area enclosed by the carbon footprint standard line and the equipment carbon footprint curve;

[0058] Second, specifically, the analysis process of the ratio when exceeding the standard is:

[0059] Obtain the carbon footprint curve of each device located above the carbon footprint standard line, record it as an analysis curve segment, obtain the time length of each analysis curve segment (the time length is calculated by the difference between the end time and the start time of the analysis curve segment), and mark it as the timeout value;

[0060] Sum up all the overtime values ​​in the analysis period to obtain the overtime value;

[0061] Then the excess time value is calculated by ratio with the analysis period to obtain the excess time ratio;

[0062] It should be noted that: the analysis cycle consists of several calculation periods;

[0063] The technical solution of the embodiment of the present invention: Calculation module: Set the calculation period to calculate the carbon footprint E of all equipment in the enterprise 总 Processing is performed to calculate the current carbon footprint value of the enterprise; measurement module: a carbon footprint model is constructed for each device, and the carbon footprint exceeding assessment value of the equipment in the enterprise is obtained by analysis, and then compared with the corresponding threshold value to determine the exceeding equipment; the present invention calculates the electricity consumption data of each device in the enterprise to obtain the overall carbon footprint data of the enterprise, and then judges whether it exceeds the standard according to the carbon footprint data of each device within the analysis period, measures the equipment in the enterprise with exceeding carbon footprint performance, realizes the calculation and measurement of the carbon footprint of the enterprise, completes the quantitative and qualitative analysis of the carbon footprint, and is convenient for the green and low-carbon management of the enterprise based on the obtained carbon footprint data.

[0064] Example 2

[0065] See also Figure 2 As shown, the present invention is a carbon emission and carbon footprint measurement system for industrial enterprises based on power big data, which also includes the following modules:

[0066] Monitoring module: Set the monitoring period, calculate the total carbon footprint of the enterprise during the monitoring period, evaluate it based on the total carbon footprint, and get the signal of whether the enterprise's carbon footprint is qualified or unqualified;

[0067] In some implementation schemes, a monitoring period is set, and the current carbon footprint value of the enterprise corresponding to each time point in the monitoring period is summed up to obtain a total carbon footprint value;

[0068] Compare the total carbon footprint value to the total carbon footprint threshold;

[0069] If the total carbon footprint value is greater than or equal to the total carbon footprint threshold, it means that the carbon footprint calculated by the enterprise during the monitoring period does not meet the set standard, and a carbon footprint failure signal for the enterprise is generated;

[0070] If the total carbon footprint value is less than the total carbon footprint threshold, it means that the carbon footprint calculated by the enterprise during the monitoring period meets the set standard, and a qualified carbon footprint signal for the enterprise is generated;

[0071] It should be noted that the values ​​of the analysis period and the monitoring period can be set to be the same or different;

[0072] Balance module: When the enterprise's carbon footprint fails to meet the standards, it determines the energy-saving transformation plan based on the equipment that exceeds the standards;

[0073] In some implementation schemes, when a signal of an enterprise's carbon footprint failure is obtained, all the equipment exceeding the standard is counted, and the production impact value of each equipment exceeding the standard is obtained;

[0074] Obtain the excess ratios of all exceeding equipment and sum them up to obtain the total excess ratio value, then calculate the ratio of the excess ratio of each exceeding equipment to the total excess ratio value to obtain the carbon footprint weight of each exceeding equipment;

[0075] The production impact values ​​of all the equipment exceeding the standard are obtained and summed to obtain the total production impact value, and then the production impact value of each equipment exceeding the standard is calculated by ratio with the total production impact value to obtain the production impact weight of each equipment exceeding the standard;

[0076] Then through the formula , calculate the rated power value PK of the operating mechanism of each exceeding-standard equipment; where a1 and a2 are proportional coefficients, a1 is 0.61, a2 is 0.39, KC is the carbon footprint weight of each exceeding-standard equipment, KS is the production impact weight of each exceeding-standard equipment, PC is the rated power of the operating mechanism in the exceeding-standard equipment, and the operating mechanism may include a motor, a hydraulic cylinder, etc.;

[0077] According to the calculated rated power value PK of the operating mechanism of each exceeding-standard equipment, the operating mechanism of the exceeding-standard equipment is replaced according to the rated power value PK;

[0078] The process of obtaining the production impact value is as follows:

[0079] Obtain the total power consumption of each exceeding-standard equipment during the monitoring period, mark it as the periodic power consumption value of the exceeding-standard equipment, and compare the periodic power consumption value of the exceeding-standard equipment with the total power consumption of the enterprise during the monitoring period to obtain the power consumption degree ratio of the exceeding-standard equipment;

[0080] Obtain the total working time of each exceeding-standard equipment in the monitoring period, and mark it as the exceeding-standard equipment cycle time value; calculate the ratio of the exceeding-standard equipment cycle time value to the monitoring period to obtain the exceeding-standard equipment operation degree ratio;

[0081] The power consumption ratio of the equipment exceeding the standard and the operating ratio of the equipment exceeding the standard are summed up and calculated to obtain the production impact value;

[0082] It should be explained that the production impact value indicates the proportion of the power consumption and production time of the equipment exceeding the standard in the monitoring period to the total, which can reflect the impact of the equipment in the production process of the enterprise. That is, the larger the production impact value, the greater the power consumption and production time of the equipment exceeding the standard, and the greater the impact on the production and operation of the enterprise. The smaller the production impact value, the smaller the power consumption and production time of the equipment exceeding the standard, and the smaller the impact on the production and operation of the enterprise.

[0083] The technical solution of the embodiment of the present invention is as follows: Monitoring module: Setting a monitoring period, calculating the total carbon footprint of the enterprise within the monitoring period, evaluating according to the total carbon footprint, and obtaining a qualified or unqualified signal of the enterprise's carbon footprint; Balancing module: Based on the unqualified signal of the enterprise's carbon footprint, determining the energy-saving transformation plan according to the equipment exceeding the standard; The present invention is based on judging whether the carbon footprint of the current enterprise is qualified during production. If it is unqualified, the operating degree of the equipment exceeding the standard and the degree of carbon emission exceeding the standard in the production process are used to reflect the proportion of the impact caused by its operating mechanism when it works. Based on the specific calculated values, the operating mechanism of the equipment exceeding the standard is updated, thereby ensuring that the equipment exceeding the standard is qualified for the enterprise's carbon footprint standard in the subsequent production process, and ensuring that the enterprise produces in a green and low-carbon environment.
