All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. In the description of the present invention, "a plurality" includes two or more unless specifically defined otherwise.
In this application, the word "exemplary" is used to mean "serving as an example, instance, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. The following description is presented to enable any person skilled in the art to make and use the invention. In the following description, details are set forth for the purpose of explanation.

In other instances, well-known structures and processes are not shown in detail to avoid obscuring the description of the invention with unnecessary detail. Thus, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles disclosed herein.
It should be noted that, currently, in the carbon emission accounting process, a carbon emission factor method is generally adopted, and the current carbon emission factor generally adopts a regional average emission factor or a provincial level average method factor, and only the carbon emission of a region or a provincial city can be estimated and controlled, and the accounting of the carbon emission cannot be implemented to individuals such as households, enterprises, universities and the like in the region, and the control and the restriction of the carbon emission of each individual are also difficult.
In the related technology, a fixed meter is installed on each individual to acquire energy consumption data, and then the data are gathered to a monitoring platform for accounting, so that the monitoring platform can receive a large amount of data, not only is the communication burden increased, but also the network is blocked, the real-time performance of the data can be reduced, and the reliability of an accounting result is further reduced.
Therefore, the application improves the traditional carbon emission metering method based on the method.
Referring to fig. 1, a method for measuring carbon emissions in this embodiment includes the following steps:
s100: selecting metering equipment according to the area to be accounted, and associating the metering equipment with the emission factor table corresponding to the area to be accounted;
specifically, the specific process of selecting the metering equipment according to the area to be accounted comprises the following steps:
s110: the device label and the position information of the metering device are acquired firstly, and it is worth explaining that the device label and the position information of the metering device are acquired through the Beidou or the GPS, and the device label and the position information of the metering device are in one-to-one correspondence.
S120: and selecting the metering equipment in the position range according to the position range of the area to be checked, specifically, matching the position range of the area to be checked with the position information of the metering equipment, and selecting the metering equipment according to the matching result.
It should be explained that different areas correspond to different metering devices, and when the carbon emission of a certain area to be accounted is known, the metering devices located in the area (i.e., the metering devices associated with the area) can be determined according to the range information of the area to be accounted and the position information of each metering device.
Then, associating the equipment label of the selected metering equipment with the emission factor table corresponding to the area to be accounted, specifically, one area to be accounted corresponds to at least one selected metering equipment, and one metering equipment corresponds to one equipment label, namely, the area to be accounted corresponds to at least one equipment label; the equipment label information of the metering equipment corresponding to the region to be accounted is added into the corresponding region emission factor table to realize mutual association, so that the emission factor table of the region to be accounted can be directly associated through the equipment label when the emission factor is inquired subsequently, and the inquiry speed of the emission factor can be greatly improved.
Further, the carbon emission metering method of the present invention further comprises the steps of,
s200: acquiring energy consumption data of an area to be accounted through the selected metering equipment, and classifying the operator type of the energy consumption data to obtain classified type data;
specifically, the steps of acquiring the energy consumption data of the area to be accounted are as follows:
s210: the metering equipment is connected with energy utilization equipment in the area to be checked, and the energy utilization equipment transmits corresponding energy utilization data to the metering equipment; wherein the energy usage data comprises energy consumption activity data and operator type.
It should be noted that the operator types include a primary type and a secondary type, and the step of classifying the operator types capable of using data to obtain the classified type data is as follows:
s220: classifying the energy consumption data according to the energy types of operators to obtain primary type data;
in some embodiments, the energy categories include power, gas, and water;
and S230, classifying the primary type data according to the type of the energy supply mode to obtain secondary type data, wherein the primary type data and the secondary type data form classified type data.
In some embodiments, when the primary type data is power supply, the type of power supply includes one or more of coal-fired power generation power supply, photovoltaic power generation power supply, nuclear power supply and hydroelectric power supply; when the primary type data is gas supply, the energy supply mode types comprise one or more of natural gas supply, liquefied petroleum gas supply and coal gas supply; when the primary type data is water supply, the energy supply mode types comprise one or more of centralized water supply and secondary water supply.
More specifically, different energy utilization devices are correspondingly equipped according to the energy types of different operators, namely different energy utilization devices (such as gas meters, water meters and electric meters) are adopted for gas supply, water supply and power supply. It should be noted that different operator types correspond to different types of data, for example, the type data of the type 1 power supply operator is D1, the type data of the type 2 power supply operator is D2, and the type data of the type 3 power supply operator is D3; the type data of the type 1 gas supply operator is Q1, the type data of the type 2 gas supply operator is Q2, and the type data of the type 3 gas supply operator is Q3; the type data of the type 1 water supply operator is S1, the type data of the type 2 water supply operator is S2, and the type data of the type 3 water supply operator is S3. The energy-using equipment stores operator type data, and when the operator is replaced, the energy-using equipment correspondingly updates the operator type data, for example, the operator type data of the energy-using equipment corresponding to power supply is D1, namely, the type 1 power supply operator is used; when the type 2 power supply operator is subsequently changed, the corresponding energy utilization equipment correspondingly updates the operator type data into D2, so that the accuracy of inquiring the corresponding emission factor can be ensured during the carbon emission measurement, and the accuracy of the carbon emission measurement is further ensured.
In some embodiments, the metering device is connected to the energy-consuming device of the specific energy type, that is, the metering device only obtains the energy-consuming data of the energy-consuming device corresponding to the specific energy type, as shown in fig. 2, the metering device 1 only obtains the energy-consuming data of the energy-consuming device (e.g., an electricity meter), and the metering device 2 only obtains the energy-consuming data of the energy-consuming device (e.g., a gas meter). It should be noted that, in some other embodiments, the metering device may obtain energy consumption device data corresponding to different energy types, as shown in fig. 3, the metering device 1 may obtain energy consumption data of the electrical device and the gas consumption device at the same time, that is, one metering device may simultaneously associate one or more energy consumption devices for supplying water, supplying gas and supplying power.
More specifically, the metering device superposes and integrates the parts of the same type in the classified energy consumption data, and transmits the integrated type to the monitoring platform, so that the data capacity can be reduced, and the transmission delay can be reduced.
It should be explained that, the present application is set as two-level classification, and more levels of classification may also be set according to actual situations. It is clear that the finer the classification, the more accurate the calculated carbon emissions.
It should be noted that by classifying the operator types capable of using data, the data traffic can be reduced in the subsequent data transmission. For example, the metering device a collects operator type data of an electricity meter a, an electricity meter B, a water meter a, a water meter B, a gas meter a and a gas meter B, the operator type data corresponding to the electricity meter a and the electricity meter B are D1, the operator type data corresponding to the water meter a is S1, the operator type data corresponding to the water meter B is S3, the operator type data corresponding to the gas meter a and the gas meter B is Q1, the operator type data collected by the metering device a includes D1, S3, Q1 and Q1, the metering device classifies the operator type data to obtain D1, S3 and Q1, and only the regional emission factors corresponding to D1, S3 and Q1 need to be queried. Only transmitting the device label and the operator type data can greatly reduce data communication traffic and greatly reduce communication burden. The carbon emission metering method of the present embodiment further includes the steps of,
s300: inquiring an emission factor table according to the metering equipment and the classification type data to obtain a corresponding emission factor;
the specific process of acquiring the corresponding emission factor is as follows:
it should be noted that the emission factor table includes a plurality of emission factor sub-tables, the emission factor sub-tables correspond to the primary types in the operator types, each emission factor sub-table includes a plurality of emission factors, and the emission factors correspond to the secondary types in the operator types;
s310, receiving an inquiry request sent by the metering equipment, wherein the inquiry request comprises an equipment label and classification type data corresponding to the metering equipment; it should be noted that the metering device sends the device label and classification type data to the monitoring platform.
In some embodiments, the region to be accounted corresponds to a plurality of metering devices, and all the emission factors in the region to be accounted are concentrated into one emission factor sub-table, which is beneficial to quickly inquiring the emission factor table according to the region.
S320: inquiring the associated emission factor table according to the equipment label, inquiring the corresponding emission factor sub-table according to the primary type data in the classification type data, and inquiring the corresponding emission factor in the corresponding emission factor sub-table according to the secondary type data in the classification type data; it should be noted that, after the emission factor is queried, the association between the device label and the emission factor table of the area to be accounted is released, that is, the device label information in the corresponding emission factor table is released, so that the memory resource can be saved.
S330: the corresponding emission factor is sent to the metering device.
S400: calculating the carbon emission according to the emission factor and the energy consumption data; the carbon emission is calculated through the metering equipment, so that the calculation resources of the monitoring platform can be saved, and the stability and the real-time performance of the carbon emission calculation are improved.
In some embodiments, the carbon emissions are calculated by the formula:
GHG discharge capacity ＝AD i electricity ×EF i electricity +AD j gas ×EF j gas +AD K water ×EF K water ；
Wherein, GHG Discharge capacity For the total carbon emission of the area to be accounted, AD i electricity Data representing energy consumption activity of an i-th power supply operator; EF i electricity Denotes AD i electricity A corresponding emission factor; AD j gas Data representing energy consumption activity of a jth gas supply operator; EF j gas Denotes AD j gas (fuel gas) A corresponding emission factor; AD K water Data representing energy consumption activity of a kth water supply operator; EF K water Denotes AD K water A corresponding emission factor; i, j and k are integers and are more than or equal to 1. The carbon emission of the area to be checked can be calculated through the calculation formula.
Referring to fig. 4, the method for controlling carbon emission according to the embodiment of the present invention, which adopts the above carbon emission metering method, further includes the following steps:
s500: setting a carbon emission reference value of an area to be accounted; specifically, a carbon emission reference value is set according to the carbon emission amount, for example, the total carbon emission amount of n regions to be accounted is Z, and the initial carbon emission reference value of each region to be accounted is Z/n.
S600: calculating the carbon emission integral of the area to be accounted according to the carbon emission reference value and the carbon emission;
specifically, the carbon emission integral of the region to be accounted for is calculated by the following formula:
setting a carbon emission reference value as a, when the carbon emission A is less than a, the carbon emission integral of unit carbon emission is Y, and the carbon emission integral of the region to be accounted is s = A × Y;
when the carbon emission A is larger than or equal to a, the carbon emission integral s of the area to be accounted is as follows:
further, the carbon emission reference value of the area to be accounted is corrected according to the carbon emission integral, and specifically, the carbon emission reference value of the area to be accounted is corrected through the following formula:
the calculation formula of the corrected carbon emission reference value is as follows:
wherein E is a carbon emission reference value after correction, a is a carbon emission reference value before correction, s is a current carbon emission integral of the region, an is the sum of the carbon emission reference values of all regions to be accounted, and Sn is the sum of the carbon emission integrals of all regions to be accounted.
It is worth mentioning that the carbon emission credit is further allocated according to the corrected carbon emission reference value of each to-be-accounted area, specifically, the total carbon emission credits of the n to-be-accounted areas are set to be Z, and the corrected carbon emission reference value of each to-be-accounted area is set to be E 1 、E 2 、E 3 …E n Then the carbon emission credit corresponding to the mth (m is more than or equal to 1 and less than or equal to n) area to be accounted is set as: z E m /(E+E 2 +E 3 +…+E n )]。
The carbon emission limit control according to the actual carbon emission conditions of different areas is effectively realized through the formula, so that the accuracy and the standardization of carbon emission control are realized. In some embodiments, the metering apparatus performs the steps of the carbon emission control method described above. And the carbon emission reference value is stored in the metering equipment or other equipment in the area so as to monitor the carbon emission of the area.
In some embodiments, the monitoring platform performs the steps of the carbon emission control method described above. And the carbon emission reference value can be sent to the metering equipment for storage, can also be stored in the monitoring platform, and is called when the carbon emission reference value needs to be used.
In addition, the control method can control carbon emission aiming at different types of energy consumption units; specifically, the carbon emission measuring method is firstly adopted to calculate the carbon emission corresponding to different energy consumption unit types, in some embodiments, a carbon emission reference value is set for different types of energy consumption units according to the carbon emission limit, and the energy consumption unit types include common home users, enterprises and colleges; the carbon emission standard value of a home user is a1, the carbon emission standard value of an enterprise is b1, and the carbon emission standard value of a college is c1; the step of calculating the carbon emission integral includes:
