Abstract

The embodiment of the invention discloses a method, device, equipment and storage medium for inspecting the quality of Internet of Vehicles data. The method includes: obtaining the target Internet of Vehicles data segment according to the time stamp of the local vehicle data segment; obtaining a sampling frequency according to the cycle of the target Internet of Vehicles data and the local vehicle data segment, and performing the local vehicle data segment according to the sampling frequency Perform resampling to obtain multiple data sequences; obtain the target data sequence according to the matching degree between the multiple data sequences and the target Internet of Vehicles data segment; calculate the correspondence between the target Internet of Vehicles data segment and the target data sequence The delay time of the data points is used to obtain a delay sequence; and the inspection result is determined according to the matching degree between the target data sequence and the target Internet of Vehicles data segment and / or the delay sequence. The method for inspecting the data quality of the Internet of Vehicles provided in this embodiment can improve the accuracy and efficiency of data inspection, and can quickly locate the cause of data quality problems.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of the Internet of Vehicles, and in particular, to a method, device, device, and storage medium for inspecting data quality of the Internet of Vehicles. Background technique [0002] The Internet of Vehicles data is the data that the on-board telematics processor (Telematics BOX, T-BOX) collects vehicle-related information (such as location information, attitude information, vehicle status information, etc.) and uploads it to the server through the wireless communication module. Accurate and real-time uploading of data to the server is the basis for realizing the function of the Internet of Vehicles, such as: remote control of the car requires real-time control of the current and real state of the vehicle after being controlled; big data analysis and mining based on user data is based on accurate uploading based on the data. Therefore, it is particularly important to test the quali...
