However, the above-mentioned vehicle-mounted data screening method is liable to cause problems of low screening efficiency and poor screening accuracy.
Based on the above, the embodiment of the application provides a vehicle-mounted data screening method to improve screening efficiency and screening accuracy of vehicle-mounted data.
Referring to fig. 1, fig. 1 is a flowchart of a vehicle-mounted data screening method according to an embodiment of the present application. As shown in fig. 1, the vehicle-mounted data screening method provided by the embodiment of the application includes:
step S101, receiving a vehicle-mounted data screening instruction.
In this step, the in-vehicle data screening instruction may refer to an instruction to start screening in-vehicle data.
The vehicle-mounted data screening instruction carries a plurality of target data packets selected by a user, key information and a derived catalog, wherein the key information is a key value pair, keys in the key value pair are used for storing a control domain, and values in the key value pair are used for storing fields to be screened.
In the embodiment of the application, in the vehicle-mounted data screening interface, a plurality of separated and compressed candidate data packets are listed, the candidate data packets are uploaded to a background server or a cloud server through different vehicle-mounted operating systems of different vehicles, and the vehicle-mounted operating systems corresponding to the candidate data packets are also stored together.

In an alternative embodiment, the key value pair corresponding to the key information includes at least one field to be filtered.
The field to be filtered may refer to a name of the field to be filtered, and illustratively, the field to be filtered may be an age or a name.

Specifically, when the number of the target data packets in the same control domain is N, the decompression processing may be sequentially performed on each target data packet to obtain N groups of decompressed data. Each decompressed data has corresponding generation time, the N groups of decompressed data are sequentially ordered according to the sequence from front to back of the generation time, and multiple groups of decompressed data are spliced together according to the ordering result to generate data to be screened.

Taking the example as an example, the key information Android is as follows: [ age, name ] is converted into a code executable object, such as: and (4) Android [ "[ age ]", "[ name ]" ], and screening the data to be screened by using the converted object to obtain a screened vehicle-mounted data screening result.
In an alternative embodiment, the data screening of the data to be screened by using the program object, to obtain the vehicle-mounted data screening result, includes: performing first-round data screening on the data to be screened by utilizing the values of keys in the program object to obtain first screening data; performing second-round data screening on the first screening data by using the value of the program object median value to obtain second screening data; and taking the second screening data as a final vehicle-mounted data screening result.
Taking the above example as an example, the Android is utilized to perform first-round data screening on the data to be screened, and the vehicle-mounted data with the Android as the vehicle-mounted operating system is screened from the data to be screened, wherein the vehicle-mounted data is the first screening data. And screening all data in age and name fields from the vehicle-mounted data of which the vehicle-mounted operating system is Android by using the ages and names, wherein the data is second screening data, namely a final vehicle-mounted data screening result.

Specifically, the user may set a data range to be screened for a certain field to be screened in the vehicle-mounted data screening interface, and for the age field, data with ages ranging from 30 to 40 may be screened for the above example. After setting the data range corresponding to the age field, the data range can be added into the vehicle-mounted data screening instruction, so that vehicle-mounted data with the age within the range of 30-40 years old can be selected from vehicle-mounted data screening results by utilizing the data range and used as a preferable vehicle-mounted data screening result.
Step S104, storing the screening result of the vehicle-mounted data in the export directory.
