and determining the original flight data frame with the earliest acquisition time from the original flight data frames which are not allocated to any analysis thread according to the sequence of the acquisition time, and taking the original flight data frame with the earliest acquisition time as the original flight data frame to be allocated.
5. The method of claim 1, wherein the parsing thread parses the original frames of flight data assigned to itself by:
selecting an unresolved original flight data frame from all the original flight data frames distributed to the resolving thread as an original flight data frame to be resolved currently;
decoding the original flight data in the original flight data frame to be analyzed by using a decoding mapping table to obtain decoded flight parameters;
determining a target dictionary corresponding to the original flight data frame to be analyzed from a plurality of dictionaries according to the decoding flight parameters;
and analyzing the original flight data in the original flight data frame to be analyzed by using the target dictionary to obtain analyzed target flight data.
6. The method according to claim 5, wherein selecting an unresolved original flight data frame from the original flight data frames allocated to the resolving thread as the original flight data frame to be resolved comprises:
and selecting the original flight data frame with the forefront allocation sequence from the unresolved original flight data frames as the original flight data frame to be resolved currently according to the allocation sequence of each original flight data frame in the resolution thread.
7. The method of claim 4, wherein the method further comprises:
receiving the parsed target flight data from each parsing thread;
storing the target flight data into a specified database according to the sequence of the acquisition time corresponding to each target flight data; the acquisition time corresponding to the target flight data is the acquisition time carried by the original flight data frame corresponding to the target flight data.
8. A flight data processing apparatus, comprising:
the dividing module is used for dividing the original flight data stream to obtain a plurality of original flight data frames;
the determining module is used for determining an original flight data frame to be allocated from the original flight data frames which are not allocated to any analysis thread;
the allocation module is used for selecting an analysis thread with the least analysis task amount from a plurality of analysis threads according to the current analysis task amount of each analysis thread, allocating the original flight data frame to be allocated to the analysis thread, and repeatedly executing the steps to determine the original flight data frame to be allocated and the subsequent steps from the original flight data frame which is not allocated to any analysis thread until all the original flight data frames are allocated to the corresponding analysis threads; the analysis thread is used for analyzing the original flight data frames distributed to the analysis thread to obtain analyzed target flight data.
9. An electronic device, comprising: a processor, a memory and a bus, said memory storing machine-readable instructions executable by said processor, said processor and said memory communicating over the bus when the electronic device is running, said machine-readable instructions when executed by said processor performing the steps of the method according to any one of claims 1 to 7.
10. A computer-readable storage medium, characterized in that it has stored thereon a computer program which, when executed by a processor, performs the steps of the method according to any of claims 1 to 7.
