Event data recording method, device and equipment and storage medium

Abstract

The invention discloses an event data recording method, device and equipment and a storage medium, and the method comprises the steps: starting to record the first risk event data of a target vehiclewhen a risk recognition result is that there is a risk, and obtaining the vehicle-mounted record data, recorded by the vehicle-mounted equipment of the target vehicle, of the target vehicle; obtaininglocally recorded operation data of the target vehicle and second risk event data; performing an accuracy test to obtain an accuracy test result; preprocessing the first risk event data, the vehicle-mounted record data of the target vehicle, the second risk event data and the operation data of the target vehicle based on an accuracy test result to obtain to-be-fused data; and performing data fusion on the to-be-fused data to obtain a target event fusion data packet. By utilizing the technical scheme provided by the invention, various event data can be integrated and stored, the accuracy of event data recording is improved, and the reliability and safety of the event data are improved.

Description

technical field [0001] The present invention relates to the technical field of Internet of Vehicles, in particular to an event data recording method, device, equipment and storage medium. Background technique [0002] With the rapid development of the automobile industry and the substantial increase in the number of automobiles, the annual casualties and property losses caused by traffic accidents also increase significantly. In order to make the driving process replayable and improve the traceability of traffic accidents for easy analysis, it is not only easy to confirm the cause of the accident, but also to learn from this accident and apply it to future safety designs. In recent years, new production All cars are equipped with EDR (Event Data Recorder event data recording system). China has also recently issued a draft national standard, requiring vehicles to be equipped with an accident data recorder (EDR) that meets the national standard requirements after January 1, 2...

AI Technical Summary

Problems solved by technology

The current EDR data recording system is mainly vehicle-mounted, which can only collect and record relevant accident information through the sensor of the vehicle. The data collection is limited and the storage capacity is small. In addition, when a secondary accident occurs, it is easy to increase the damage of the vehicle-mounted EDR. probability, no additional backup of data

And due to the limitation of receiving equipment hardware, the vehicle EDR data processing capacity is low

And when the on-board EDR is damaged or fails, it is difficult to obtain accident-related data
