Description

Technical Field

[0001] The present invention relates to the field of data processing, and in particular to a real-time emission inventory calculation method, device and electronic equipment. Background Art

[0002] Motor vehicle exhaust emissions are considered one of the main sources of urban air pollution. Accurately quantifying motor vehicle emissions and their impact on air quality is a key support for implementing motor vehicle pollution management strategies. This quantification process is usually referred to as emission inventory construction.

[0003] Emission inventories can be divided into two categories: static and dynamic according to different classification standards. The generation of static emission inventories mainly relies on the analysis of basic information such as the number of motor vehicles in a certain area, annual growth rate, proportion of vehicle types, and frequency of driving activities, so as to evaluate the overall motor vehicle emissions in the area over a longer period of time (such as one year). The characteristics of this type of inventory are wide coverage and long periodicity, but the corresponding estimation error is also large. In contrast, dynamic emission inventories focus on real-time monitoring of the actual driving status of motor vehicles in specific sections or smaller areas, and calculate emissions by collecting parameters such as real-time speed and road length. Compared with static inventories, dynamic inventories have the advantages of small assessment areas, short periods, and relatively small estimation errors.

[0004] Currently, the construction of dynamic emission inventories usually relies on portable emission test systems (PEMS) to measure the actual emission levels of vehicles on the road on site. Subsequently, a database of motor vehicle emission factors is constructed to support the calculation process of the dynamic inventory. However, the estimation accuracy of this method is often limited, which affects the overall accuracy of the emission inventory. Summary of the invention

[0034] The real-time emission inventory calculation method provided by the embodiment of the present invention can be applied to Figure 1 The emission inventory calculation system 1000 includes a service device 110, a client device 120 and a verification device 130.

[0039] Please refer to Figure 2 , is a block diagram of an electronic device 2000, which may be Figure 1 The service device 110 in the emission inventory calculation system 1000 is shown. The electronic device 2000 includes a memory 210, a processor 220, and a communication module 230. The memory 210, the processor 220, and the communication module 230 are electrically connected to each other directly or indirectly to achieve data transmission or interaction.

[0041] The processor 220 is used to read / write data or programs stored in the memory 210 and execute corresponding functions. For example, Figure 1 In the emission inventory calculation system 1000 shown, the processor 220 of the service device 110 executes a computer program stored in the memory to implement the real-time emission inventory calculation method provided in the embodiment of the present invention.

[0042] The communication module 230 is used to establish a communication connection between the electronic device 2000 and other communication terminals through the network, and to send and receive data through the network. Figure 1 In the emission inventory calculation system 1000 shown, the service device 110 transmits and receives data with the client device 120 and the inspection device 130 respectively through the network.

[0043] It should be understood that Figure 2 The structure shown is only a schematic diagram of the structure of the electronic device 2000. The electronic device 2000 may also include Figure 2 More or fewer components as shown, or with Figure 2 Different configurations shown. Figure 2 Each component shown in the figure can be implemented by hardware, software or a combination thereof.

[0044] Please refer to Figure 3 The real-time emission inventory calculation method provided by the embodiment of the present invention includes step 10 and steps 21 to 25, and Figure 1 The service device 110 in the emission inventory calculation system 1000 shown may Figure 2 The structure shown in FIG. 1 is used to execute the above step 10 and step 21 to step 25 to implement the real-time emission inventory calculation method.

[0045] Step 10: construct and store a motor vehicle factor library corresponding to various energy types.

[0046] Among them, the motor vehicle factor library includes the emission factor library of gasoline vehicles, and the emission factor library of gasoline vehicles includes the gasoline vehicle environmental inspection factor library, the gasoline vehicle brand and model factor library and the gasoline vehicle correction factor library. The gasoline vehicle environmental inspection factor library records the emission factors of each fuel vehicle that has undergone emission inspections, the gasoline vehicle brand and model factor library records the emission factors of each model of gasoline vehicles under each brand, and the gasoline vehicle correction factor library records the emission factors of each model of gasoline vehicles after correction by regional influence factors.

[0047] Step 21, when the basic information of the target vehicle is obtained, the energy type of the target vehicle is determined.

[0048] Step 23, when the energy type is gasoline, select the emission factor library with the highest matching degree with the basic information from the emission factor library of gasoline vehicles as the target factor library.

[0049] Step 25, according to the basic information, obtain the matching emission factor from the target factor library, and calculate the real-time emission inventory of the target vehicle based on the emission factor.

[0050] For example, in combination Figure 1 In the emission inventory calculation system 1000 shown, the service device 110 retrieves the motor vehicle emission periodic inspection data from each inspection device 130, and uses the motor vehicle emission periodic inspection data to construct and store a motor vehicle factor library corresponding to the energy type, and the energy type includes but is not limited to: gasoline, diesel, liquefied petroleum, natural gas, etc., that is, motor vehicles include but are not limited to gasoline vehicles, diesel vehicles, liquefied petroleum vehicles, natural gas vehicles and hybrid vehicles, etc.

[0051] Here, when constructing the motor vehicle emission factor library, the types of pollutant inspections and related influencing factors for vehicles of various energy types specified in the current "Technical Guidelines for the Preparation of Air Pollutant Emission Inventories for Road Motor Vehicles" (hereinafter referred to as the "Guidelines") are used as a guide for construction. For example, if the gasoline vehicle pollutants specified in the guidelines include carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx), and the pollutant emissions of gasoline vehicles are related to brand, model, emission stage, age, vehicle speed, region, etc., then the emission factor library includes the gasoline vehicle emission factor library, the gasoline vehicle emission factor library includes the gasoline vehicle environmental inspection factor library, the gasoline vehicle brand model factor library and the gasoline vehicle correction factor library, the gasoline vehicle environmental inspection factor library records the emission factors of each fuel vehicle that has undergone emission inspections, the gasoline vehicle brand model factor library records the emission factors of each model of gasoline vehicles under each brand, and the gasoline vehicle correction factor library records the emission factors of each model of gasoline vehicles after correction by regional influencing factors, and the emission factors include the emission factors corresponding to CO, HC and NOx.

[0052] After the motor vehicle factor database is constructed, the service device 110 may periodically obtain the latest motor vehicle emission periodic inspection data, and update the motor vehicle factor database with the latest motor vehicle emission periodic inspection data.

[0053] At the same time, the constructed motor vehicle factor library is put into use. Therefore, when any emission calculation personnel sends an emission calculation request to the service device 110 through the client device 120, the service device 110 parses the target vehicle and the basic information of each target vehicle from the emission calculation request. In addition, for each target vehicle, the service device 110 determines the energy type of the target vehicle. When the energy type is gasoline, the target factor library with the highest matching degree with the basic information is selected from the emission factor library of gasoline vehicles, and the matching emission factor is obtained from the target factor library, and the real-time emission inventory of the target vehicle is calculated with the emission factor.

[0054] Among them, the emission inventory calculation formula of the target vehicle can be: , Characterizes the emission factor of a certain pollutant (unit: g / km), Represents the mileage (in actual calculation, the length of the section between the two downstream intersections of the road where the monitoring equipment is located is taken, unit: kilometer).

[0055] Next, the real-time emission inventory of each target vehicle is summarized to obtain the overall emission inventory.

[0056] In traditional motor vehicle emission factor libraries, portable emission test systems are usually used to test the emission levels of vehicles on actual roads, and then the average emission factors are calculated based on the test data to establish a motor vehicle emission factor library. This method has the following defects: (1) The representativeness of the emission factors is very limited: the number of vehicle models involved in the test is very small, resulting in a significant lack of representativeness of the emission factor data; (2) The cost is high. In addition, when estimating real-time motor vehicle emissions, a general average emission factor is generally used, which has low estimation accuracy and is difficult to represent real-time motor vehicle emissions.

[0057] In the above-mentioned real-time emission inventory calculation method provided by the present invention, the actual emission factors of the emission inspection of motor vehicles, the influence of brand models and the influence of regions are taken into consideration to construct multiple emission factor libraries of different granularities, that is, emission factor libraries of different precisions, so as to calculate the emission inventory with the target factor library with the highest degree of matching with the basic information of the target vehicle, that is, the emission inventory is calculated with the most accurate emission factor library, so that the emission factors finally selected are more representative, which greatly improves the calculation precision and overall accuracy of the emission inventory.

[0058] In order to improve the accuracy and representativeness of the motor vehicle factor library, the motor vehicle emission periodic inspection data and the comprehensive benchmark emission coefficients of various energy types specified in the guidelines are introduced in step 10 to construct the motor vehicle factor library. Figure 4 , step 10 may include steps 11 to 17.

[0059] Step 11, for motor vehicles whose energy type is gasoline, retrieve the motor vehicle emission periodic inspection data, and build an emission factor library for gasoline vehicles in combination with the regional impact factors of gasoline pollutants.

[0060] Step 13, for motor vehicles whose energy type is diesel, retrieve the comprehensive benchmark emission coefficient of diesel vehicles, and build a diesel vehicle correction factor library in combination with the regional impact factors of diesel pollutants.

[0061] Step 15, for motor vehicles whose energy type is other fuels, retrieve the comprehensive benchmark emission coefficient of this type of fuel vehicles, and build an emission factor library for this type of fuel vehicles based on the comprehensive benchmark emission coefficient.

[0062] Step 17, according to a preset ratio, combining the gasoline vehicle correction factor library and the diesel vehicle correction factor library to construct an emission factor library for vehicles with unknown energy sources.

[0063] Among them, other fuels refer to any power fuel other than gasoline or diesel, such as natural gas, coal-to-liquids, and hydrogen fuel cells.

[0064] In step 11, in order to accurately obtain the gasoline vehicle environmental inspection factor library, gasoline vehicle brand model factor library and gasoline vehicle correction factor library of gasoline vehicles, any method can be used. For example, the regular motor vehicle emission inspection data of gasoline vehicles can be sorted to obtain the gasoline vehicle environmental inspection factor library, and then the gasoline vehicle environmental inspection factor library can be processed using a pre-trained classification model or function to obtain the gasoline vehicle brand model factor library, and the gasoline vehicle environmental inspection factor library can be corrected using a pre-trained correction model or correction function to obtain the gasoline vehicle correction factor library. A preset method can also be used to construct an emission factor library for gasoline vehicles. The above method is only an example, and its implementation method is not limited.

[0065] In order to make the emission factor library of gasoline vehicles with different precision more representative, refer to Figure 5 , including steps 111 to 118.

[0066] Step 111, retrieve the characteristic registration information and inspection data of each inspected gasoline vehicle from the retrieved motor vehicle emission periodic inspection data.

[0067] The inspection data includes the inspection time, the inspection vehicle speed at each moment during the inspection time, and the emission quality of each gasoline pollutant. The characteristic level information includes but is not limited to: license plate number, license plate color, vehicle brand, fuel type, vehicle type, vehicle model, emission stage, registration date, inspection date, temperature, speed range, and each pollutant emission coefficient (i.e., pollutant emission amount).

[0068] Step 112, for each inspected gasoline vehicle, calculate the equivalent driving distance and total emissions in each preset speed range based on the inspection data of the inspected gasoline vehicle, and obtain the primary emission factor in each speed range based on the equivalent driving distance and total emissions.

[0069] Here, the speed range division can be flexibly selected, for example, it can be divided into 4 speed ranges of 0~20km / h, 20~30km / h, 30~40km / h, and greater than 40km / h, or it can be divided into 0~30km / h, 30~50km / h, and greater than 50km / h. The above speed division method is only an example, and its implementation method is not limited.

[0070] Similarly, the calculation method of equivalent driving distance can also be set flexibly. The period when the vehicle speed is within the speed range is taken as the target period, and the equivalent driving distance can be the sum of the speeds of the gasoline vehicles that have been inspected during the target period, and the equivalent driving distance can be the driving distance of the gasoline vehicles that have been inspected during the target period. For example, the period of 20~30 km / h is t2~t5, and the vehicle speeds are v2~v5 respectively, then the equivalent driving distance = v2+…+v5, or the sum of the driving distances of the gasoline vehicles that have been inspected during t2~t5.

[0071] Since gasoline produces a lot of pollutants, in step 112, the emission factors of each pollutant in each speed range are calculated. For example, for each pollutant, the sum of the emission masses of the pollutant in the target period is calculated to obtain the total emission of the pollutant-free. Furthermore, for each speed range, the total emission of the pollutant-free in the target period corresponding to the speed range is divided by the equivalent driving distance of the target period corresponding to the speed range to obtain the primary emission factor (also understood as the primary emission coefficient or primary emission factor) of each pollutant, that is, the primary emission factor = total emission of the pollutant-free / equivalent driving distance.

[0072] Step 113, the characteristic registration information of the inspected gasoline vehicles and each primary emission factor are stored correspondingly to obtain a gasoline vehicle environmental inspection factor library.

[0073] Here, when storing the primary emission factor, the vehicle speed range corresponding to the primary emission factor is also stored. The data correspondence in the gasoline vehicle replacement factor library includes but is not limited to: characteristic registration information - vehicle speed range - primary emission factor.

[0074] Step 114, each primary emission factor in the gasoline vehicle environmental inspection factor library is divided and calculated according to the brand model and the speed range, so as to obtain the secondary emission factor of each speed range of each brand model.

[0075] After classification according to brand model and speed range, the classification results shown in the classification table in Table 1 below can be obtained.

[0076] Table 1 Classification table

[0077] After obtaining the classification results, for each speed range under each brand model, the inspected gasoline vehicles of this brand signal within the speed range are selected as the selected vehicles. According to the first-level environmental inspection factors (i.e., first-level emission coefficient or first-level emission factor) corresponding to each selected vehicle, the second-level emission factor (i.e., second-level emission coefficient or second-level emission factor) of this brand model in this speed range is obtained by selecting the median, calculating the arithmetic mean, taking the highest frequency value, etc.

[0078] Step 115, according to the corresponding relationship, the secondary emission factors are stored with the corresponding vehicle speed ranges and brand models to obtain a gasoline vehicle brand model factor library.

[0079] After executing step 115, the data correspondence recorded in the gasoline vehicle brand model factor library includes but is not limited to: brand - model - vehicle speed range - primary emission factor.

[0080] Step 116, based on the regional impact factor of gasoline pollutants, the retrieved comprehensive baseline emission coefficient of gasoline vehicles is corrected to obtain a gasoline vehicle correction factor for each emission type, and the gasoline vehicle correction factor and emission type are stored in correspondence to obtain a gasoline vehicle basic factor library.

[0081] Among them, the same emission type has the same vehicle type, emission stage, registration year, temperature and speed range, and the emission stages include National Zero, National I, National II, National III, National IV and National V. The comprehensive benchmark emission factor is a factor table specified in the guidelines, which records the motor vehicle type, emission stage and corresponding emission factor.

[0082] Here, the method of correcting the comprehensive benchmark emission coefficient can be flexibly selected. For example, the product of the regional impact factor and the comprehensive benchmark emission coefficient can be used as the gasoline vehicle correction factor, or the comprehensive benchmark emission coefficient can be corrected by combining the regional impact factor and the emission periodic inspection data. Moreover, the above method is only an example, and its implementation method is not limited.

[0083] The regional influencing factors of gasoline pollutants include temperature correction factor, humidity correction factor, average speed correction factor and degradation correction factor. Among them, there are multiple temperature correction factors, each temperature correction factor corresponds to a temperature value or a temperature range, there are multiple humidity correction factors, each humidity correction factor corresponds to a humidity value or a humidity range, there are multiple average speed correction factors, each average speed correction factor corresponds to an average speed or an average speed range, there are multiple degradation correction factors, each degradation correction factor corresponds to a degree of degradation, and each degradation range is determined by a motor vehicle type, an emission stage and a registration year.

[0084] In order to make the obtained gasoline vehicle basic factor library more representative of the pollutant emissions of gasoline vehicles in a certain region, the idea of ​​combining regional influencing factors and emission periodic inspection data is introduced in the revision process. Figure 6 The correction process in step 116 may include steps 1161 to 1163.

[0085] Step 1161, dividing the regional impact factors of gasoline pollutants in a permutation and combination manner to obtain multiple impact groups.

[0086] It should be understood that each impact group includes a temperature correction factor, a humidity correction factor, an average speed correction factor, and a degradation correction factor.

[0087] Step 1162, read all comprehensive benchmark emission coefficients of gasoline vehicles.

[0088] Step 1163, for each comprehensive benchmark emission coefficient, multiply the comprehensive benchmark emission coefficient by each impact group to obtain multiple gasoline vehicle correction factors.

[0089] The calculation formula of the gasoline vehicle correction factor can be expressed as: , Characterizes the comprehensive benchmark emission factor, Characterizes the temperature correction factor in the impact group, Characterize the humidity impact factor in the impact group, Characterizes the average speed correction factor in the impact group, Characterizes the degradation correction factor in the impact group.

[0090] In the gasoline vehicle basic factor library obtained by storing the gasoline vehicle correction factor and the emission type in correspondence, the data correspondence can be in the form of: emission type-gasoline vehicle correction factor, and the emission type includes vehicle type, emission stage, registration year, temperature and speed range.

[0091] Step 117, according to the emission type of gasoline vehicles, the primary emission factors of gasoline pollutants are divided into multiple type groups, the third-level emission factors of each type group are calculated, and the third-level emission factors and emission types are stored correspondingly to obtain the gasoline vehicle environmental inspection secondary library.

[0092] It should be noted that in step 117, gasoline pollutants with the same emission type (i.e., the same vehicle type, emission stage, registration year, temperature and speed range) in the gasoline vehicle environmental inspection factor library are taken as a type group. And for each pollutant in the type group, the first-level emission factor of the pollutant-free in the type group is processed by selecting the median, calculating the average value, selecting the highest frequency value, etc., to obtain the third-level emission factor of the pollutant in the type. The data correspondence in the gasoline vehicle environmental inspection secondary library obtained in the end can be in the form of: emission type-third-level emission factor.

[0093] Step 118, based on the gasoline vehicle environmental inspection secondary library, the gasoline vehicle basic factor library is corrected to obtain the gasoline vehicle correction factor library.

[0094] The method of correcting the gasoline vehicle basic factor library can be flexibly selected. For example, the third-level emission factor and gasoline vehicle correction factor with the same emission type can be extracted from the gasoline vehicle basic factor library and the gasoline vehicle environmental inspection secondary library, and the third-level emission factor can be used as the final emission factor in the gasoline vehicle correction factor library. The third-level emission factor and gasoline vehicle correction factor with the same emission type can also be proportionally integrated or averaged to obtain the final emission factor in the gasoline vehicle correction factor library. The above method is only an example, and its implementation method is not limited.

[0095] The final correspondence in the gasoline vehicle correction factor library can be in the form of: emission type-corrected emission factor.

[0096] Through the above steps 111 to 118 and related sub-steps, based on the motor vehicle periodic emission inspection data, a gasoline vehicle environmental inspection factor library consistent with the actual pollution situation of the inspected gasoline vehicles is established, and then the gasoline vehicle environmental inspection factor library is classified by brand model and vehicle speed to obtain a gasoline vehicle brand model factor library that can represent the actual pollution situation of various brand models, and the regional impact factor and the gasoline vehicle environmental inspection factor library are used to correct the comprehensive benchmark emission coefficient to obtain a gasoline vehicle correction factor library that can represent the actual pollution situation of each emission type of gasoline vehicles. Thus, a gasoline vehicle emission factor library with higher representativeness and different precision (i.e., different granularity) is obtained, which helps to improve the accuracy of emission inventory calculation.

[0097] When diesel vehicles are actually tested for emissions, usually only one pollutant is tested, which is not representative. In order to make the diesel vehicle correction factor library more accurate and representative, the same correction concept as the above step 116 is introduced in step 13, that is, the comprehensive benchmark emission factor of diesel vehicles in the guidelines is corrected by using regional influence factors to obtain an emission factor consistent with the diesel pollution situation in the region where the diesel vehicle is located. Figure 7 , step 13 includes step 131 to step 132.

[0098] Step 131, based on the regional impact factor of diesel pollutants, the retrieved comprehensive benchmark emission coefficient of diesel vehicles is corrected to obtain the emission factor of diesel vehicles of each emission type.

[0099] The regional influencing factors of diesel pollutants include at least temperature correction factor, humidity correction factor and differential correction factor. There are multiple temperature correction factors, each corresponding to a temperature value or a temperature range. There are multiple humidity correction factors, each corresponding to a humidity value or a humidity range. There are multiple vehicle speed correction factors, each corresponding to a vehicle speed value and an emission stage.

[0100] Similar to step 116, the regional impact factors of diesel pollutants are divided in a permutation and combination manner to obtain multiple impact groups, each of which includes a temperature correction factor, a humidity correction factor, and a vehicle speed factor. Then, for the comprehensive benchmark emission coefficient of each diesel vehicle, the comprehensive benchmark emission coefficient is multiplied by each impact group to obtain multiple diesel vehicle emission factors.

[0101] Step 132, storing the diesel vehicle emission factors and emission types in correspondence to obtain a diesel vehicle correction factor library.

[0102] The corresponding relationship in the final gasoline vehicle correction factor library can be in the form of: emission type-corrected diesel vehicle emission factor.

[0103] Through the above steps 131 to 132, based on the diesel vehicle comprehensive benchmark emission coefficient provided by the guideline, and using the temperature correction factor, humidity correction factor and vehicle speed correction factor corresponding to the region for correction, a more accurate and representative diesel vehicle correction factor library is obtained, thereby helping to improve the accuracy of emission inventory calculation.

[0104] For step 15, the emission factor library for motor vehicles of other fuel types may be constructed in the same manner as steps 131 to 132, or in the same manner as steps 111 to 117, which is not limited in this embodiment.

[0105] In order to estimate the emission inventory of vehicles of the location energy type as accurately as possible, in step 17, the emission factors of gasoline vehicles and diesel vehicles corresponding to the same speed range can be extracted from the gasoline vehicle correction factor library and the diesel vehicle correction factor library as the same speed group, and the average, median or highest frequency value of the emission factors in the same speed group can be used as the emission factor of the unknown energy vehicle in this speed range. Alternatively, the emission factors in the same speed group can be calculated according to the ratio of gasoline vehicle: diesel vehicle = 7:3. The above method is only an example, and its implementation method is not limited.

[0106] In the process of calculating the emission inventory by constructing the motor vehicle factor library in the above manner, in order to match the most accurate target factor library as much as possible, the idea of ​​matching from the highest accuracy to the lowest accuracy is introduced in step 23. Figure 8 , step 23 may include steps 231 to 235.

[0107] Step 231, determine whether the basic information includes the characteristic registration information of the target vehicle. If yes, execute step 232, if not, execute step 233.

[0108] The basic information may include all information of the target vehicle obtained by the traffic checkpoint system or the motor vehicle remote sensing monitoring system to which the client device 120 is connected in communication, such as the license plate number, vehicle speed, temperature, license plate color, and other data. In addition, after the client device 120 recognizes the license plate number, it extracts any one or several of the vehicle brand, energy type, vehicle type, vehicle model, emission stage, registration date, and inspection date corresponding to the license plate number from the pre-set vehicle annual inspection database, vehicle registration database, and other databases, and combines them to obtain more complete basic information. If there is no data in the database, the basic information only includes the license plate number, vehicle speed, temperature, license plate color, and other data obtained by the traffic checkpoint system or the motor vehicle remote sensing monitoring system.

[0109] Step 232: Use the gasoline vehicle environmental inspection factor library as the target factor library.

[0110] Step 233, determine whether the basic information includes the brand, model and speed of the target vehicle. If yes, execute step 234, if not, execute step 235.

[0111] Step 234, using the gasoline vehicle brand model factor library as the target factor library.

[0112] Step 235, using the gasoline vehicle correction factor library as the target factor library.

[0113] Through the above steps 231 to 235, matching is performed from the ring check factor library with the highest accuracy to match the most accurate target factor library as much as possible.

[0114] After step 21 above, refer to Fig. 9 The real-time emission inventory calculation method provided in this embodiment of the present invention also includes step 24.

[0115] Step 22, when the energy type is diesel, obtain a matching emission factor from a diesel vehicle correction factor library according to the emission type of the target vehicle, and calculate a real-time emission inventory of the target vehicle based on the emission factor.

[0116] It should be noted that the emission type is data extracted from the basic information of the target vehicle.

[0117] Similarly, please continue to refer to Fig. 9 , also including step 24 and step 26.

[0118] Step 24, when the energy type is other fuel, according to the model and emission stage of the target vehicle, obtain the matching emission factor from the emission factor library of other fuel vehicles, and calculate the real-time emission inventory of the target vehicle based on the emission factor.

[0119] Step 26, when the energy type is unknown, according to the emission type of the target vehicle, obtain a matching emission factor from the emission factor library of unknown energy vehicles, and calculate the real-time emission inventory of the target vehicle based on the emission factor.

[0120] Through the above method, when estimating the emission inventory of other fuel vehicles or diesel vehicles, the emission factors corrected by the regional impact factors of the region are used for calculation, so that the estimation accuracy of the emission inventory is higher. At the same time, when the energy is unknown, the emission factor library of unknown energy vehicles is used for calculation, and the emission factor library is composed of the emission factors of gasoline and diesel vehicles corrected by the regional impact factors, which also improves the calculation accuracy of the emission inventory of unknown energy vehicles.

[0121] Based on the same concept as the above real-time emission inventory calculation method, refer to Fig.10 The embodiment of the present invention further provides a real-time emission inventory calculation device 3000, including a construction module 310, an energy judgment module 320, a factor library matching module 330 and a matching calculation module 340.

[0123] The energy determination module 320 is used to determine the energy type of the target vehicle when the basic information of the target vehicle is acquired.

[0124] The factor library matching module 330 is used to select the emission factor library with the highest matching degree with the basic information from the emission factor library of gasoline vehicles as the target factor library when the energy type is gasoline.

[0125] The matching calculation module 340 is used to obtain the matching emission factor from the target factor library according to the basic information, and calculate the real-time emission inventory of the target vehicle based on the emission factor.
