AI Technical Summary
Technical Problem
In existing technologies, data backfeeding methods ensure accuracy by modifying the timestamp of each backfeeding message, resulting in a large workload and low efficiency in data processing.
Method used
Obtain message data from the autonomous driving domain controller, extract the start timestamp, and send it to the autonomous driving domain controller at a preset time to adjust its system time, ensuring timestamp consistency. Then, when the system time adjustment is complete, perform message data backfeed.
Benefits of technology
By aligning the system time of the autonomous driving domain controller with the start timestamp of the message data, the workload of data processing was reduced and the efficiency of data feedback was improved.

Abstract
The application discloses a data backfilling method and device, electronic equipment and a storage medium. The method comprises the following steps: obtaining message data of an automatic driving domain controller; extracting a starting time stamp in the message data, and sending the starting time stamp to the automatic driving domain controller according to a preset time, so as to adjust the time of the automatic driving domain controller system to the starting time stamp of the message data; the starting time stamp is the starting time of collecting the message data, and the preset time is a time earlier than the backfilling starting time of the message data by a preset value; and when the time adjustment of the automatic driving domain controller system is completed, the message data is backfilled to the automatic driving domain controller. Through the method, the time of the automatic driving domain controller system is modified to be consistent with the starting time stamp of the message data, and then the message data is backfilled to the automatic driving domain controller, so that the problem of large data processing workload is solved, and the efficiency of backfilled data is improved.
