Embodiment 1

[0034] Such as figure 1 As shown, this embodiment proposes a method for calculating vehicle ownership, including

[0035] S1. Obtain the registration information of the motor vehicle business. The registration information of the motor vehicle business includes vehicle model, license plate number, license plate type, nature of use, vehicle type, date of initial registration, fuel type, engine model, deadweight, and expiration of mandatory retirement period , Administrative divisions and motor vehicle status, such as figure 2 Shown

[0036] S2, take the vehicle model as the connection attribute, grab the announcement information, and intercept the emission standards in the announcement information; take the commercial vehicle network as an example, the page is like image 3 As shown, enter in the page figure 2 Take the vehicle model LZW1010P as an example to obtain the announcement information of the vehicle model, such as Figure 4 (Interception of part of the announcement informat...

Embodiment 2

[0050] A calculation system for vehicle ownership, including:

[0051] The first parameter acquisition module is used to acquire motor vehicle business registration information. The motor vehicle business registration information includes vehicle model, number plate number, number plate type, nature of use, vehicle type, date of initial registration, fuel type, engine model, load Weight, mandatory retirement period, administrative divisions and state of motor vehicles;

[0052] The second parameter acquisition module is used to use the vehicle model as the connection attribute to capture the announcement information, and intercept the emission standards in the announcement information;

[0053] A generating module, configured to generate an individual vehicle full life cycle database according to the motor vehicle business registration information and the emission standard;

[0054] The first arithmetic module is used to select the base year, and calculate the number of eliminated and...

Embodiment 3

[0064] A device for calculating the possession of a motor vehicle, the device comprising a memory and a processor, wherein:

[0065] The memory is used to store executable program code;

Abstract

The invention discloses a motor vehicle ownership calculation method, system and device, and a medium. The method comprises the steps: obtaining motor vehicle business registration information; capturing announcement information by taking a vehicle model as a connection attribute, and intercepting an emission standard in the announcement information; constructing an individual vehicle full life cycle database according to the motor vehicle business registration information and the emission standard; selecting a reference year, calculating the elimination number and the newly increased number of the motor vehicles according to the initial registration date and the forced scrapping period end attribute in the individual vehicle full life cycle database, and calculating the number of each vehicle model according to the elimination number and the newly increased number; and solving the proportion of each vehicle model according to the number of each vehicle model, counting annual identification data based on the motor vehicle ownership, and summing the total ownership of each vehicle model. The beneficial effects of the invention are that the method achieves the optimization of the calculation of the motor vehicle ownership through the motor vehicle ownership calculation method based on the technical features of the full life cycle of an individual vehicle, is more comprehensive and accurate in the obtained motor vehicle ownership, and improves the accuracy of an emission list result.

Description

Technical field [0001] The present invention relates to the field of computer application technology, in particular to a method, system, device and medium for calculating the possession of motor vehicles. Background technique [0002] Motor vehicle exhaust emissions account for a very large proportion of urban pollution sources in my country, so when studying the impact of motor vehicle emissions on urban air quality, motor vehicle emission inventories are extremely important reference materials. [0003] Existing regional motor vehicle emission inventories at the provincial level and above are based on motor vehicle inventory data, while the existing motor vehicle inventory data is too general and not comprehensive enough, making the results of the emission inventory uncertain and impossible. Used for analysis of various pollution sources. Summary of the invention [0004] In view of the above-mentioned problems, the present invention proposes a method, system, device and medium f...
