Problems solved by technology

However, in practical applications, if one component field in the composite field changes, it often triggers other component fields to change accordingly.
Therefore, the desired information may not be extracted from only one component field, or the extracted information may be incomplete, resulting in one-sided data acquisition, which in turn affects the analysis results of the entire composite field

Abstract

The embodiment of the invention provides an information extraction method and device for the Internet of Vehicles. The information extraction method for the Internet of Vehicles comprises the following steps of: acquiring information of a component field in a driving area composite field of a vehicle, and determining a field function of the driving area composite field based on the information ofthe component field; sampling the information of the component field to obtain sampled data; and based on the field function and the sampled data, determining frequency spectrum information corresponding to the sampled data, and extracting abnormal information from the sampled data according to the frequency spectrum information so as to carry out traffic early warning on vehicles in the Internetof Vehicles. According to the technical scheme provided by the embodiment of the invention, abnormal information in the composite field of the driving area is extracted based on the frequency spectruminformation of the sampled data, so that the accuracy of data acquisition is improved, and the completeness of the acquired data is ensured at the same time.

Description

technical field [0001] The present application relates to the field of computer and communication technologies, and in particular, to a method and device for extracting information of the Internet of Vehicles. Background technique [0002] In the monitoring process of many composite fields, the existing technology often monitors a single component field, and analyzes the data of a single component field to obtain the analysis results of the entire composite field. However, in practical applications, if a component field in the composite field changes, it often triggers other component fields to change accordingly. Therefore, the desired information may not be extracted from only one component field, or the extracted information may be incomplete, resulting in one-sided data acquisition, which in turn affects the analysis results of the entire composite field. Contents of the invention [0003] The embodiments of the present application provide a method and device for extr...
