Embodiment 1

[0057] see figure 1 , in an embodiment of the present invention, a method for filtering data of the Internet of Vehicles, comprising the following steps:

[0058] Step S10, stroke data.

[0059]In this embodiment, the itinerary data refers to: the original data of the Internet of Vehicles collected at the device end is merged into the itinerary data at the server end. Here, the device side includes, but is not limited to, vehicle built-in equipment, hardware used in the vehicle, and mobile platforms such as smartphones.

[0060] Step S20, preliminary processing and storage.

[0061] Filter the obtained itinerary data, remove the obviously wrong itinerary data and keep the original itinerary as much as possible. Specific definitions of obviously wrong itinerary data include, but are not limited to:

[0062] 1) The number of satellite positioning points is less than or equal to 5;

[0063] 2) The travel time is less than 30 seconds;

[0064] 3) The travel mileage is less t...

Abstract

The invention discloses a method for filtering car networking data. The method for filtering car networking data comprises the following steps: primarily processing traveling data; correcting and precisely filtering the traveling data after the traveling data are stored into a warehouse; and processing the data for different applications, recognizing abnormal working states of equipment, detectingfabricating data and filtering out the fabricating data. The obtained traveling data are filtered, the traveling data which are mistake obviously are removed, and the original travel is maintained asmuch as possible. The step of correcting and precisely filtering the traveling data after the traveling data are stored into the warehouse comprises: correcting abnormal data points; and removing mistaken data points. The traveling data of an equipment end are acquired and processed primarily, and the problem that mistaken traveling data are uploaded to a server to occupy storage space and resources is avoided. The traveling data are filtered and corrected, and the precision and stability of an algorithm are further improved. The accuracy and stability of follow-up applications such as driving behavior analyzing application and traveling analyzing and drawing application will be enhanced.

Description

technical field [0001] The invention relates to the technical field of sensors and data processing, in particular to a method for filtering data of the Internet of Vehicles. Background technique [0002] In modern life, the wide application of car networking data benefits insurance companies, OEMs, car after-sales services and car owners. The existing collection method generally collects all the data on the vehicle or regularly collects according to a certain period. If you use the full collection method, when some information on the vehicle appears frequently, but the content of the information is mostly unchanged, then many identical information will be collected and a large amount of redundant data will be generated. And use the timing method to collect data according to a certain period, then when the collection frequency is higher than the data change frequency, the appearance of redundant data cannot be avoided; on the contrary, when the collection frequency is lower ...
