It should be understood that the implementation examples described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0033] Embodiment 1:

[0034] A carbon emission accounting method for a residential area comprises the following steps:

[0035] Step 1: Count the number of buildings in the community and determine the calculation start time node T1 and the calculation end time node T2;

[0036] Step 2: Count the carbon emissions of buildings and structures in the community;

[0037] The buildings in residential areas generally include apartment buildings, kindergartens, security rooms and other types of ancillary facilities. The total electricity meter and total natural gas meter data of each building are connected to the carbon emission management system, so that the carbon emission management system can grasp the energy data of each building in real time. All buildings are numbered in a certain order. Suppose there are N buildings in the community, T1 is the calculation start time node, T2 is the calculation end time node (T2-T1 is in hours), and the value of each building meter at T1 is E T11 、E T12 、E T13 ,…,E T1N (unit: kWh), the electric meter value of each building at T2 is E T21 、E T22 、ET23 ,…,E T2N (Unit: kWh).

[0040] Among them, E T2n is the electricity meter value of the nth building at the end time node T2, E T1n is the meter value of the nth building at the starting time node T1, where N is the total number of buildings. is the total carbon emissions of all buildings and structures in the residential area during the period T1 to T2 (tCO2); BE 电力 is the carbon emissions (tCO2) generated by electricity consumption of all buildings and structures in the residential area during the period T1 to T2; BE 天然气 It is the carbon emission (tCO2) generated by natural gas consumption of all buildings and structures in the residential area during the period T1 to T2. 电力 is the CO2 emission factor of electricity, in tons of CO2 / MWh (tCO2 / MWh), using the latest published value of the national grid average emission factor of the Ministry of Ecology and Environment; Q T2n is the natural gas meter value of the nth building at the end time node T2, Q T1n NCV is the natural gas meter value of the nth building at the starting time node T1. 天然气 The average low calorific value of natural gas, expressed in million kilojoules per 10,000 cubic meters (GJ / 10,000 Nm 3 ), the default value of 389.31 GJ / 10,000 Nm can be used 3 ;CC 天然气 The carbon content per unit calorific value of natural gas is expressed in tons of carbon per million kilojoules (tC / GJ). The default value of 0.0153tC / GJ can be used. 天然气 It is the carbon oxidation rate of natural gas, in %, and the default value of 99% can be used.

[0041] Step 3: Count carbon emissions in the community’s public areas

[0042] The carbon emission sources in the public areas of residential areas generally include underground garage facilities (underground garage lighting and electric vehicle charging piles), as well as ground facilities (electric vehicle charging piles and street lights). The meter data of each public facility is connected to the carbon emission management system. Assume that the meter value of each public facility at T1 is G T1地下车库照明 , G T1地下车库汽车充电桩 , G T1地面电动车充电桩 , G T1地面路灯 (unit: kWh), the value of each public utility meter at T2 is G T2地下车库照明 , G T2地下车库汽车充电桩 , G T2地面电动车充电桩 , G T2地面路灯 (Unit: kWh).

[0043] Then the total carbon emissions in the public area during the period T1 to T2 is:

[0044] BG CO2 =BG 电力

[0045] =(G T2地下车库照明 +G T2地下车库汽车充电桩 +G T2地面电动车充电桩 +G T2地面路灯

[0046] -G T1地下车库照明 -G T1地下车库汽车充电桩 -G T1地面电动车充电桩 -G T1地面路灯 )×EF 电力 ×10 -3 Among them, BE CO2 is the total carbon emissions (tCO2) of all facilities in the public areas of the residential area during the period T1 to T2; BE 电力 G is the carbon emissions (tCO2) generated by electricity consumption of all facilities in the public areas of the residential area during the period T1 to T2; T2地下车库照明 , G T2地下车库汽车充电桩 , G T2地面电动车充电桩 , G T2地面路灯 are the meter values ​​of underground garage lighting, underground garage car charging piles, ground electric vehicle charging piles, and ground street lights at the end time node T2 of the calculation, respectively. T1地下车库照明 , G T1地下车库汽车充电桩 , G T1地面电动车充电桩 , G T1地面路灯 are the meter values ​​of underground garage lighting, underground garage car charging piles, ground electric vehicle charging piles, and ground street lights at the calculation start time node T1, respectively. 电力 It is the CO2 emission factor of electricity, with the unit of tonne CO2 / MWh (tCO2 / MWh), and adopts the latest published value of the national grid average emission factor of the Ministry of Ecology and Environment.

[0047] Step 4: Count the carbon emissions generated by traffic in the community

[0048] Since the carbon emissions generated by the power consumption of household electric vehicles have been calculated through the electric meter data of the electric vehicle charging piles in the community's underground garage, and the carbon emissions generated by the power consumption of household electric bicycles have been calculated through the electric meter data of the electric vehicle charging piles on the ground in the community, they are no longer counted again. The carbon emissions generated by the traffic flow refer to the carbon emissions generated by household fuel vehicles, external electric bicycles (including express delivery, take-out), etc. driving within the community boundary. The total carbon emissions generated by the traffic flow in the residential area during the time period T1 to T2 is:

[0049]

[0050] Among them, BW CO2 BW is the total carbon emissions generated by traffic in the residential area during the period T1 to T2 (tCO2); 住户燃油车 BW is the carbon emissions (tCO2) generated by gasoline consumption of household fuel vehicles of all residents in the residential area during the period T1 to T2 within the community boundary; 外来电动车 is the carbon emissions (tCO2) generated by the electricity consumption of all external electric vehicles in the residential area during the period T1 to T2. Suppose the number of household fuel vehicles in the community is M, and all household fuel vehicles are numbered from 1 to M in a certain order, m is the number of household fuel vehicles, then ω m is the fuel consumption per 100 kilometers of the mth household fuel vehicle, in liters per 100 kilometers. The property management can register the models of household fuel vehicles of the owners in the community and obtain the fuel consumption data per 100 kilometers from the manufacturers and suppliers of various models of vehicles; L m NCV is the distance traveled by the mth household fuel vehicle within the community boundary during the time period T1 to T2, in meters. This data can be obtained through the location monitoring platform (the location monitoring platform consists of several location monitoring devices, which can be installed on the basis of the existing monitoring system in the community to accurately identify the identity of vehicles in the community and accurately obtain location information, thereby generating the trajectory information of the target vehicle and connecting the location monitoring platform to the carbon emission management system). 汽油 The average lower calorific value of gasoline, expressed in million kilojoules per 10,000 cubic meters (GJ / 10,000 Nm 3 ), the default value of 43.070 GJ / 10,000 Nm can be used 3 ;CC 汽油 The carbon content of gasoline per unit calorific value is expressed in tons of carbon per million kilojoules (tC / GJ). The default value of 0.0189tC / GJ can be used. 汽油 It is the carbon oxidation rate of gasoline, in %, and the default value of 98% can be used. It means that the volume of 1 ton of No. 92 gasoline is equal to 1000 / 0.725≈1379 liters. Suppose that a total of M1 external electric vehicles enter the community during the time period T1-T2. All external electric vehicles are numbered from 1 to M1 in chronological order, where m1 is the number of the external electric vehicle, and σ m1 is the power consumption per 100 kilometers of the m1th external electric vehicle, in kWh / 100 kilometers, which can be estimated at 4 kWh / 100 kilometers; l m1 The driving distance of the m1th external electric vehicle within the community boundary during the time period T1 to T2, in meters.

[0051] Step 5: Count the carbon emissions generated by the flow of people in the community;

[0052] The facial recognition system at the gate of the community accurately identifies the time nodes of all residents and outsiders entering and leaving the community, and connects the facial recognition system to the carbon emission management system. Suppose that a total of S residents have been in the community from T1 to T2, and I residents enter the community. The time points of entering the community are t Ii (i=1,2,3,…,I), J residents leave the community, and the time points of leaving the community are t Ji (j=1,2,3,…,J), P outsiders have been in the community, Q outsiders enter the community, and the time points of entering the community are t Qq (q=1,2,3,…,Q), R outsiders leave the community, and the time points of leaving the community are t Rr (r=1,2,3,…,R), it is known that a person emits about 40 grams of carbon dioxide per hour through breathing. The total carbon emissions generated by the flow of people in the residential area during the period T1 to T2 is:

[0055] Step 6: Calculate the total carbon emissions of the residential area based on the carbon emissions of buildings, public areas, vehicles, and people.

[0056] Assume that the total carbon emissions of the residential area is The unit is tCO2. Then:
