Data resending method, device and equipment

Abstract

The embodiment of the invention discloses a data reissuing method, device and equipment. The method comprises the following steps: receiving reported data of a vehicle-mounted terminal, wherein the reported data is data sent to the cloud by the vehicle-mounted terminal according to a preset frequency; judging the type of the reported data according to the data type identifier of the reported data; if the type of the reported data is real-time data, the cloud judges whether data packet loss occurs in the reported data received by the cloud according to the numerical value of the received message serial number; and if the data packet loss occurs, the cloud sends a data reissuing request to the vehicle-mounted terminal, so that the vehicle-mounted terminal performs data reissuing. By adopting the method provided by the embodiment of the invention, the situation that data reissuing needs to be carried out due to disconnection and poor network signals is considered, and the accuracy and integrity of after-event reissuing of the vehicle-mounted data can be realized, so that a guarantee is better provided for safe driving of the vehicle.

Description

technical field [0001] This specification relates to the field of vehicle networks, and in particular to a data reissuing method, device and equipment. Background technique [0002] In the Internet of Vehicles system, the on-board equipment on the vehicle reports the driving status data of the vehicle to the cloud through wireless communication technology, which provides a basis for cloud-based vehicle data analysis and the realization of various application scenarios. However, during the process of reporting data by the vehicle terminal, the reported data may be lost due to reasons such as connection disconnection or network packet loss. Therefore, in order to ensure the integrity of the vehicle data reported to the cloud, the vehicle terminal needs to reissue the data not received by the cloud. [0003] In the prior art, after-the-fact reissuance of the on-board data is realized by receiving the reported data from the on-board vehicle through the cloud, and then confirmin...

AI Technical Summary

Problems solved by technology

The existing post-event reissuance of vehicle data is mainly aimed at the situation that the cloud does not receive the reported data due to disconnection

However, for the situation that the real-time data of the vehicle-mounted terminal cannot be reported to the cloud due to poor network signal or network equipment failure in a short period of time, the post-event reissue method of the prior art cannot realize data reissue, thus causing the vehicle-mounted terminal incomplete real-time data
