However, if telemetry data has frame loss / disorder and bit errors, it will be inconvenient for data processing and interpretation, affecting the timeliness and effectiveness of the test, and even interfere with command decisions and key controls.

[0021] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0022] like Figure 1 , which is a flow chart of a processing method based on multi-source telemetry data provided by an embodiment of the present invention.

[0023] A processing method based on multi-source telemetry data, the method comprising at least the following steps:

[0024] S101, obtaining multiple telemetry source code frames corresponding to target telemetry information; wherein the multiple telemetry source code frames are used to indicate telemetry source code frames corresponding to telemetry frames transmitted by the telemetry object for the same telemetry information and arriving at the first device via different base stations;

[0025] S102, performing integrity check on each of the multiple telemetry source code frames to obtain a check result;

[0026] S103, if the verification result indicates that the multiple telemetry source code frames have not passed the verification, each of the multiple telemetry source code frames is parsed, and a plurality of parsing results are optimally processed to output a parsing result corresponding to the target telemetry information;

[0027] S104, if the verification result indicates that at least one telemetry source code frame has passed the verification, then the at least one telemetry source code frame is optimized for intra-frame information to generate an optimized telemetry source code frame; the optimized telemetry source code frame is parsed to output a parsing result corresponding to the target telemetry information.

[0028] In S101, in order to obtain multiple telemetry source code frames corresponding to the target telemetry information, the received telemetry source code frames are sorted according to the frame sequence number. Since the telemetry data is transmitted through different communication links and different routes, the data packets have different delay times, and the order in which the telemetry frames arrive at the first device may be inconsistent with the order in which the telemetry objects are transmitted. Therefore, it is necessary to sort the telemetry source code frames first: preferably, the telemetry frames are inserted into a circular linked list according to the frame sequence number, and the order of the linked list and the structural characteristics of the head-to-tail connection are used to realize the parallel operation of data access and processing; preferably, a data structure such as a one-way linked list or a two-way linked list can be used to realize the sorting of multiple source code frames according to the frame sequence number. Therefore, the first device improves data utilization, accurately restores the telemetry parameter results, and reduces the losses caused by data frame loss / disorder and bit errors by receiving multiple telemetry source code frames corresponding to a telemetry data of the telemetry object.

[0029] For example, the telemetry object transmits the first frame of telemetry data, and the first frame sequence number is marked in the telemetry data; multiple ground base stations receive the first frame of telemetry data, and the multiple ground base stations respectively forward the received telemetry data frames, and the frame sequence number of the frame forwarded by the ground base station is the frame sequence number of the received frame, that is, the first frame sequence number sent by the telemetry object; the first device receives the telemetry frames forwarded by multiple ground base stations, and the first device sorts the received telemetry source code frames according to the frame sequence number. Since the received frame sequence numbers are all the first frame sequence numbers marked by the telemetry object, they are sorted in the order of the received source code frames;

[0030] In addition, when the first device receives the telemetry data, the transmission time of the telemetry frame transmitted by the telemetry object is obtained according to the reception time of the first device minus the data transmission link consumption, and the telemetry frame transmission time of the telemetry object is calibrated for the received telemetry data frame;

[0031] The data transmission link takes time The calculation method is as follows:

[0032] Formula (1);

[0033] Formula (2);

[0034] Formula (3);

[0035] in, is the time consumed by the data transmission link, and It consists of two parts: is the radio wave delay, which is the ratio of the distance R between the telemetry object and the ground station at that moment to the speed of light C; is the channel delay, which is the ratio of the telemetry frame length (Fl) to the channel bandwidth (B).

[0036] After a full frame period, that is, after a period in which the telemetry object transmits telemetry data, the telemetry object sends a second frame of telemetry data, which is marked as the second frame number in the telemetry data; when the first device receives the telemetry frame with the second frame number, it stops receiving the telemetry data frame with the first frame number and starts processing the received telemetry frame set with the first frame number. Therefore, when the telemetry frame with the second frame number is received, the telemetry frame with the first frame number is processed, which improves the real-time performance of data processing;

[0037] The process starts to process the telemetry frame set with the first frame sequence number received: the telemetry object transmission time corresponding to the first telemetry frame with the first frame sequence number received is taken as the first transmission time of the telemetry object, and each frame in the telemetry frame set is traversed. If the time difference obtained by subtracting the telemetry object transmission time corresponding to the telemetry frame from the first transmission time of the telemetry object is less than a preset threshold, the frame is considered to be a valid frame corresponding to the first frame sequence number; preferably, the preset threshold is 1 / 5 of the full frame period. Thus, the abnormal data is filtered out through the telemetry object transmission time corresponding to the multi-source code frame, thereby improving the integrity and validity of the telemetry data.

[0038] In S102, an integrity check is performed on each of the multiple telemetry source code frames to obtain a check result.

[0039] For example, a CRC check and a synchronization code check are performed on each frame of the source code frame set corresponding to the first frame sequence number transmitted by the telemetry object. If both the CRC check and the synchronization code check of the frame pass, the source code frame is marked as passing the check; if at least one of the CRC check and the synchronization code check is different, the source code frame is marked as failing the check;

[0040] After all source code frames have been verified, the verification results of each frame of the source code frame set are traversed. If the verification result of at least one source code frame is marked as passed, the source code frame set is marked as passed; if the verification results of all source code frames are marked as failed, the source code frame set is marked as failed.

[0041] In S103, if the verification result indicates that none of the multiple telemetry source code frames have passed the verification, each of the multiple telemetry source code frames is parsed, and a plurality of parsing results are optimally processed to output a parsing result corresponding to the target telemetry information. Thus, by parsing each frame in the source code frame set, data utilization is improved, telemetry parameter results are accurately restored, and losses caused by data frame loss / disorder and bit errors are reduced.

[0042] For example, if the verification result of the source code frame set corresponding to the first frame sequence number transmitted by the telemetry object fails, each frame in the source code frame set is parsed:

[0043] Decode each source code frame according to the decoding rules to obtain data corresponding to multiple parameters; after decoding all frames in the source code frame set, each parameter can determine a corresponding candidate data set. If the majority selection preset condition is met, the optimal parameter is selected from the candidate set according to the majority principle; if the majority selection preset condition is not met, the median in the candidate data set is calculated as the optimal parameter.

[0044] The synchronization code is a field carried in the telemetry data transmitted by the telemetry object, and is used to identify a unique telemetry object.

[0045] The decoding is a process of parsing data according to the communication protocol between the telemetry object and the first device.

[0046] In S104, if the verification result indicates that at least one telemetry source code frame has passed the verification, the at least one telemetry source code frame is optimized for frame information to generate an optimized telemetry source code frame; the optimized telemetry source code frame is parsed to output a parsing result corresponding to the target telemetry information. Thus, by processing the telemetry source code frame set, the integrity and validity of the telemetry data are ensured as much as possible.

[0047] For example, if the verification result of the source code frame set corresponding to the first frame sequence number transmitted by the telemetry object is passed, each frame in the source code frame set is compared to see whether the source code of each byte of the data in the frame is consistent:

[0048] If the data in the frame is completely consistent, the telemetry source code frame is selected and output according to the majority principle; if the data in the frame is not completely consistent, it means that part of the telemetry frame data has jumped, then according to the majority principle, the inconsistent sub-sections are replaced by the majority, and a new credible frame is generated and output as the optimal telemetry source code frame.

[0049] The first device of the embodiment of the present invention determines the source code frame set corresponding to the same telemetry data based on the frame sequence number and the time when the telemetry object transmits the data, thereby filtering out abnormal data and improving the real-time and effectiveness of the telemetry data. Afterwards, the source code frame set data is classified and processed, thereby improving the data utilization rate, accurately restoring the telemetry parameter results, and reducing the losses caused by data frame loss / disorder and bit errors by parsing each frame in the source code frame set. Finally, the parsing result of the telemetry object transmission data is obtained.

[0050] In a preferred implementation manner of this embodiment, based on the analysis result corresponding to the target telemetry information, the confidence of each telemetry source code frame corresponding to the analysis result is determined, and log information corresponding to the target telemetry information is generated; a number of the log information are analyzed, and the telemetry source code frame with the largest confidence is selected from a number of telemetry source code frames as the quasi-telemetry source code frame corresponding to the target telemetry information; and the base station corresponding to the quasi-telemetry source code frame is used as the quasi-base station for outputting the target telemetry information.

[0051] The log information is used to record the base station information of the telemetry source code frame and the measurement and control conditions at that time. After the tracking arc is completed, the log information is statistically analyzed to build and gradually optimize the selection strategy. The measurement and control conditions and data characteristics of the selected optimal data are statistically analyzed to determine which link target telemetry information has higher quality under specific tracking conditions.

[0052] like Figure 2 As shown, it is a schematic diagram of the process of parsing frames of a telemetry source code frame set that fails to pass verification in one embodiment of the present invention.

[0053] The frame parsing of the telemetry source code frame set that fails to pass the verification includes at least the following steps:

[0054] S201, determining a plurality of telemetry parameters corresponding to a plurality of telemetry source code frames based on at least one telemetry parameter corresponding to each telemetry source code frame;

[0055] S202, dividing the plurality of telemetry parameters according to telemetry parameter types to obtain at least one telemetry parameter set;

[0056] S203, for any telemetry parameter set in at least one telemetry parameter set: performing statistics on the telemetry parameter set; if the statistical result indicates that the telemetry parameter set satisfies the majority selection principle, selecting a quasi-telemetry parameter from the telemetry parameter set based on the majority; if the statistical result indicates that the telemetry parameter set does not satisfy the majority selection principle, determining a quasi-telemetry parameter corresponding to the telemetry parameter set based on the median;

[0057] S204, taking the quasi-telemetry parameters corresponding to each telemetry parameter set as the parsing result corresponding to the target telemetry information, and outputting the parsing result.

[0058] For example, if the verification result of the source code frame set corresponding to the first frame sequence number transmitted by the telemetry object fails, each frame in the source code frame set is parsed:

[0059] Decode each source code frame according to the decoding rules to obtain data corresponding to multiple parameters; after decoding all frames in the source code frame set, each parameter can determine a corresponding candidate data set. If the majority selection preset condition is met, the optimal parameter is selected from the candidate set according to the majority principle; if the majority selection preset condition is not met, the median in the candidate data set is calculated as the optimal parameter.

[0060] Therefore, by analyzing each frame in the source code frame set, data utilization can be improved, telemetry parameter results can be accurately restored, and losses caused by data frame loss / disorder and bit errors can be reduced.

[0061] like Figure 3 As shown, it is a schematic diagram of the process of determining the optimized telemetry source code frame through verification of the telemetry source code frame set in one embodiment of the present invention.

[0062] The telemetry source code frame set determines the optimized telemetry source code frame through verification, which at least includes the following steps:

[0063] S301, if at least one telemetry source code frame includes a telemetry source code frame, taking the telemetry source code frame as an optimized telemetry source code frame;

[0064] S302, if at least one telemetry source code frame includes a plurality of telemetry source code frames, compare the intra-frame information of each telemetry source code frame in the plurality of telemetry source code frames; if the comparison result indicates that the intra-frame information satisfies the majority selection principle, optimize the intra-frame information of the telemetry source code frame according to the majority to generate an optimized telemetry source code frame; if the comparison result indicates that the intra-frame information does not satisfy the majority selection principle, optimize the intra-frame information of the telemetry source code frame according to the median to generate an optimized telemetry source code frame;

[0065] For example, if the verification result of the source code frame set corresponding to the first frame sequence number transmitted by the telemetry object is passed, each frame in the source code frame set is compared to see whether the source code of each byte of the data in the frame is consistent:

[0066] If the data in the frame is completely consistent, the telemetry source code frame is selected and output according to the majority principle; if the data in the frame is not completely consistent, it means that part of the telemetry frame data has jumped, then according to the majority principle, the inconsistent sub-sections are replaced by the majority, and a new credible frame is generated and output as the optimal telemetry source code frame.

[0067] Therefore, by processing the telemetry source code frame set, the integrity and validity of the telemetry data can be ensured as much as possible.
