the analysis sub-module is used for analyzing the data packet to be transmitted of the current geographical position after repackaging to obtain the data type of the data to be transmitted of the current geographical position, wherein the data type comprises a file, short message data and video stream data.
8. The system for improving timeliness of data transmission of claim 7 wherein the weighted averaging processing sub-module comprises:
the matching subunit is used for matching the current geographic position with the pre-built chip so as to acquire the communication information of each communication module in the current geographic position;
and the comparison subunit is used for comparing the bandwidth and the time delay of the communication information of each communication module in the current geographic position with the communication information of the data type corresponding to the data to be transmitted in the current geographic position so as to determine the communication module meeting the bandwidth requirement and the time delay requirement.
