[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] It should be noted that in the description of the present invention, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "include one..." do not exclude the existence of other identical elements in the process, method, article or device including the elements. The orientation or position relationship indicated by the terms "upper", "lower" and the like is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the two elements. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The terms "first", "second", etc. in the present invention are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present invention can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" means at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0028] When a rocket is tested in a laboratory or assembly plant, test personnel are generally only equipped with one telemetry station to receive the telemetry data of the entire rocket test. The telemetry data received in this way is definitely correct, unique and continuous, and there is no telemetry data splicing process. However, during the actual flight of the rocket, multiple telemetry ground stations will be deployed on the ground along the rocket's flight trajectory to ensure that the rocket's entire telemetry data can be received. Since each telemetry ground station is located in a different position, the size and coverage time of the telemetry data it receives are inconsistent, and the data quality varies. The first and last data of the telemetry data from adjacent ground stations will also be repeated.

[0029] In the process of processing telemetry data, it is necessary to sort and splice the telemetry data of each station to obtain a complete, non-repetitive and continuous telemetry data; in the related art, the processing of telemetry data is generally carried out in chronological order, and the data of each station is cross-referenced and analyzed, de-duplicated, and finally the data of each station is spliced, but this method cannot accurately find the best quality telemetry data during the data splicing process, which may cause the final data to be lost or have data errors. It can be seen that the processing method of rocket telemetry data in the related art has the technical problem of not being able to accurately obtain high-quality telemetry data.

[0030] To solve at least some of the above problems, the following Figure 1-Figure 6 The invention describes the rocket telemetry data processing method, device, electronic equipment and storage medium provided by the invention.

[0031] The method for processing rocket telemetry data provided by the present invention can be applied to the scenario of processing multiple telemetry data measured by multiple telemetry ground stations; the method for processing rocket telemetry data provided by the present invention can be executed by a server, and the server is used to receive multiple telemetry data measured by multiple telemetry ground stations, and execute the method for processing rocket telemetry data provided by the present invention on the multiple telemetry data.

[0032] Figure 1 FIG. 1 is one of the flow charts of the method for processing rocket telemetry data provided by the present invention, such as Figure 1 As shown, including but not limited to the following steps:

[0033] Step 101 : read a plurality of first telemetry data into a buffer area with a full frame as the minimum unit, wherein each of the plurality of first telemetry data includes a group of full frames.

[0034] The multiple first telemetry data are telemetry data measured respectively by multiple telemetry ground stations during the rocket launch process. The first telemetry data may include different time periods during the rocket launch process. For example, a telemetry ground station closer to the rocket launch point can measure the telemetry data in the early stage of the rocket launch, and a telemetry ground station farther away from the rocket launch point can measure the telemetry data in the later stage of the rocket launch.

[0035] Here, the buffer area is used to store multiple full frames of the first telemetry data for implementation of subsequent processing steps, and the buffer area can be set in the server.

[0036] Each of the multiple first telemetry data includes a group of full frames. Here, the full frame refers to a complete data transmission unit in telemetry technology, which includes all necessary information that the telemetry system needs to transmit.

[0037] In this embodiment, multiple first telemetry data are read into the cache area with the full frame as the smallest unit. Since the multiple first telemetry data are telemetry data measured by multiple telemetry ground stations during the rocket launch process, there may be full frames acquired at the same time between different first telemetry data, and the frame counts of the full frames acquired at the same time are the same; here, the frame count is a unique serial number used to identify the full frame.

[0038] Step 102: Obtain a frame count list, wherein the frame count list includes frame counts of all full frames in the buffer, and each frame count in the frame count list corresponds to at least one full frame in the buffer.

[0039] The frame count list includes the frame counts of all full frames in the cache. The full frames in the cache include the telemetry data of the entire rocket launch process. Therefore, the frame count list records the frame counts of the entire rocket launch process; each frame count in the frame count list corresponds to at least one full frame in the cache.

[0040] Step 103, taking each frame count in the frame count list as a target frame count and executing the following steps to obtain a target full frame corresponding to the target frame count, and splicing multiple target full frames in the order of the frame count list to obtain second telemetry data:

[0041] Step 1031, determining a group of full frames to be optimized, wherein each full frame to be optimized in the group of full frames to be optimized is a full frame corresponding to the target frame count in the buffer area, and each full frame to be optimized in the group of full frames to be optimized includes a group of subframes;

[0042] Step 1032: when a group of full frames to be optimized includes multiple full frames to be optimized, a group of target subframes for constituting a target full frame is determined from the group of full frames to be optimized based on the synchronization words of the subframes of each full frame to be optimized in the group of full frames to be optimized.

[0043] A group of full frames to be optimized includes at least one full frame to be optimized, and each full frame to be optimized includes a group of subframes. Here, the subframe is the next level time or data unit of the full frame, that is, the full frame is composed of multiple subframes.

[0044] In the case where a group of full frames to be optimized includes multiple full frames to be optimized, a group of target subframes for constituting a target full frame is determined from the group of full frames to be optimized based on the synchronization words of the subframes of each full frame to be optimized in the group of full frames to be optimized; based on the synchronization words of the subframes, it can be determined whether the subframe is a high-quality subframe, and then a group of target subframes for constituting the target full frame can be determined from the group of full frames to be optimized, where each subframe in the group of target subframes is a high-quality subframe, and a high-quality subframe means that the data quality of the subframe is better and the data accuracy of the subframe is higher.

[0045] It should be noted that the specific method of judging whether a subframe is a high-quality subframe based on the synchronization word of the subframe may be to judge whether the synchronization word of the subframe meets the preset expected value, and judge the subframe to be a high-quality subframe if the synchronization word of the subframe meets the preset expected value; it may also be to compare the synchronization word of the subframe with a preset threshold, and judge the subframe to be a high-quality subframe if the synchronization word of the subframe is greater than or equal to the preset threshold.

[0046] Exemplarily, a group of full frames to be optimized includes three full frames to be optimized, namely A, B, and C. Each full frame to be optimized includes 64 subframes. There are three subframes to choose from for each position corresponding to each subframe in a group of target subframes. For the subframe position with sequence number 1, the first subframe in A, B, and C can be identified and judged based on the synchronization word of the subframe, and the subframe with the highest quality is selected as the first subframe with sequence number 1 in a group of target subframes. And so on, traverse the 64 subframe positions, and finally obtain a group of target subframes with the best quality, and the target full frame is composed of a group of target subframes.

[0047] The target full frame is a full frame corresponding to the target frame count. Multiple target full frames are spliced ​​in the order of the frame count list to obtain the second telemetry data, that is, high-quality telemetry data processed by the rocket telemetry data processing method of this embodiment.

[0048] Through the embodiments provided by the present application, multiple first telemetry data are read into the buffer area with full frames as the smallest unit, wherein each of the multiple first telemetry data includes a group of full frames; a frame count list is obtained, wherein the frame count list includes frame counts of all full frames in the buffer area, and each frame count in the frame count list corresponds to at least one full frame in the buffer area; each frame count in the frame count list is used as a target frame count to perform the following steps to obtain a target full frame corresponding to the target frame count, and multiple target full frames are spliced ​​in the order of the frame count list to obtain the second telemetry data: a group of to-be-collected frames is determined Optimize the full frame, wherein each full frame to be optimized in a group of full frames to be optimized is a full frame corresponding to the target frame count in the cache area, and each full frame to be optimized in a group of full frames to be optimized includes a group of subframes; in the case that a group of full frames to be optimized includes multiple full frames to be optimized, based on the synchronization words of the subframes of each full frame to be optimized in a group of full frames to be optimized, a group of target subframes used to form a target full frame are determined from a group of full frames to be optimized, which can solve the technical problem of the inability to accurately obtain high-quality telemetry data in the processing method of rocket telemetry data in the related art, thereby improving the data quality of the telemetry data.

[0049] As an optional solution, after determining a group of full frames to be optimized, the following is further included:

[0050] S11, when a group of full frames to be optimized includes one full frame to be optimized, determining the one full frame to be optimized as a target full frame.

[0051] When a group of full frames to be optimized includes one full frame to be optimized, it means that the number of full frames corresponding to the target frame count in the cache is 1, that is, it means that at the time point corresponding to the target frame count, only one telemetry ground station measured the telemetry data of the rocket. Therefore, at this time, one full frame to be optimized can be directly determined as the target full frame.

[0052] Through this embodiment, when a group of full frames to be optimized includes one full frame to be optimized, the target full frame is directly determined to be obtained, thereby improving the processing efficiency of the rocket telemetry data processing method.

[0053] As an optional solution, in the case where a group of full frames to be optimized includes multiple full frames to be optimized, based on the synchronization words of the subframes of each full frame to be optimized in the group of full frames to be optimized, a group of target subframes for constituting a target full frame is determined from the group of full frames to be optimized, including:

[0054] S21, determining a target full frame to be optimized, where the target full frame to be optimized is a full frame to be optimized with the most qualified subframes in a group of full frames to be optimized, and the synchronization word of the qualified subframe is equal to a preset expected value;

[0055] S22, when the number of qualified subframes in the target full frame to be optimized is equal to the preset frame value, the target full frame to be optimized is determined as the target full frame, wherein the preset frame value is obtained by subtracting the preset value from the sub-frame length of the target full frame to be optimized.

[0056] In the case that a group of full frames to be optimized includes multiple full frames to be optimized, a target full frame to be optimized is determined from the group of full frames to be optimized, the target full frame to be optimized is the full frame to be optimized with the most qualified subframes in the group of full frames to be optimized, and the synchronization word of the qualified subframe is equal to the preset expected value; if the synchronization word of the subframe is equal to the preset expected value, it means that the subframe is a high-quality qualified subframe. Here, the subsequent steps of confirming the target full frame are based on the full frame to be optimized with the most qualified subframes.

[0057] When the number of qualified subframes in the target full frame to be optimized is equal to the preset frame value, the target full frame to be optimized can be directly determined as the target full frame, wherein the preset frame value is obtained by subtracting the preset value from the sub-frame length of the target full frame to be optimized; the sub-frame length is used to indicate the number of subframes in the target full frame to be optimized; it should be noted that, for the target full frame to be optimized, the synchronization word of the last subframe included therein is a specific synchronization word, therefore, when the number of qualified subframes in the target full frame to be optimized is equal to the preset frame value, it can be said that all subframes in the target full frame to be optimized meet the standards.

[0058] It should be noted that the preset value is the number of subframes in the target full frame to be optimized, regardless of whether they are qualified subframes.

[0059] Preferably, the preset value is 1.

[0060] Exemplarily, the target full frame to be optimized includes 64 subframes, and the synchronization word of the 64th subframe is a specific synchronization word. Therefore, the 64th subframe is not considered in the method of this embodiment, and the preset value is 1; when the number of qualified subframes in the target subframe to be optimized is equal to 63, it means that all subframes of the target full frame to be optimized are qualified subframes, and the target full frame to be optimized can be directly determined as the target full frame.

[0061] Through this embodiment, when the number of qualified subframes in the target full frame to be optimized is equal to the preset frame value, the target full frame to be optimized is directly determined as the target full frame, thereby improving the processing efficiency of the rocket telemetry data processing method.

[0062] As an optional solution, after determining the target full frame to be optimized, it also includes:

[0063] S31, when the number of qualified subframes in the target full frame to be optimized is less than the preset frame value, determining a group of subframes to be qualified, wherein the group of subframes to be qualified are subframes in the target full frame to be optimized whose synchronization words are not equal to the preset expected value;

[0064] S32, taking each of the subframes to be achieved in a group of subframes to be achieved as a target subframe to be achieved, and performing the following steps to obtain a target replacement subframe corresponding to the target subframe to be achieved, and replacing a group of subframes to be achieved in the target full frame to be optimized with a group of target replacement subframes to obtain a group of target subframes:

[0065] Traversing a group of other full frames to be optimized, obtaining a group of replacement subframes to be confirmed from the group of other full frames to be optimized, wherein the position of each replacement subframe to be confirmed in the group of replacement subframes to be confirmed in the corresponding other full frames to be optimized is the same as the position of the target subframe to be achieved in the target full frame to be optimized, and the group of other full frames to be optimized are the full frames to be optimized except the target full frame to be optimized in the group of full frames to be optimized;

[0066] When there is a to-be-confirmed replacement subframe in a group of to-be-confirmed replacement subframes whose synchronization word is equal to a preset expected value, the to-be-confirmed replacement subframe is determined as a target replacement subframe.

[0067] When the number of qualified subframes in the target full frame to be optimized is less than the preset frame value, it means that there are subframes that do not meet the standard in the target full frame to be optimized, and a group of subframes to be met is determined, wherein a group of subframes to be met are subframes in the target full frame to be optimized whose synchronization words are not equal to the preset expected value; the position of each to-be-confirmed replacement subframe in a group of to-be-confirmed replacement subframes in the corresponding other full frames to be optimized is the same as the position of the target to-be-confirmed subframe in the target full frame to be optimized, for example, when the sequence number of the target to-be-confirmed subframe in the target full frame to be optimized is 10, the sequence number of each to-be-confirmed replacement subframe in the corresponding other full frames to be optimized in a group of to-be-confirmed replacement subframes is also 10, and a group of to-be-confirmed replacement subframes is traversed, and when there is a to-be-confirmed replacement subframe whose synchronization word is equal to the preset expected value, the to-be-confirmed replacement subframe is determined as the target replacement subframe.

[0068] Through this embodiment, a set of target subframes can be accurately obtained, thereby improving the accuracy of the rocket telemetry data processing method.

[0069] As an optional solution, after traversing a group of other full frames to be optimized and obtaining a group of replacement subframes to be confirmed from the group of other full frames to be optimized, the method further includes:

[0070] S41, when there is no synchronization word of the to-be-confirmed replacement subframe in the group of to-be-confirmed replacement subframes equal to the preset expected value, calculating the bit error rates of the group of to-be-confirmed replacement subframes and the target to-be-confirmed subframes;

[0071] S42, selecting a subframe with the smallest bit error rate among a group of to-be-confirmed replacement subframes and target to-be-met subframes as a target replacement subframe.

[0072] In this embodiment, the Hanning weight method is a window function, which is usually used to reduce spectrum leakage in signal processing. When calculating the bit error rate of a subframe, the Hanning weight method can be used to preprocess the signal to reduce interference between adjacent subframes; after calculating the bit error rates of a group of to-be-confirmed replacement subframes and target to-be-met subframes, a subframe with the smallest bit error rate among the group of to-be-confirmed replacement subframes and target to-be-met subframes is selected as the target replacement subframe.

[0073] Through this embodiment, the target replacement subframe can be accurately obtained, thereby improving the accuracy of the rocket telemetry data processing method.

[0074] As an optional solution, before reading the plurality of first telemetry data into the buffer area with full frames as the minimum unit, the method further includes:

[0075] S51, dividing the target telemetry data into first target telemetry data and second target telemetry data, wherein the initial plurality of first telemetry data includes the target telemetry data and other telemetry data, the first target telemetry data is the telemetry data before rocket ignition, and the second target telemetry data is the telemetry data after rocket ignition;

[0076] S52, combining the second target telemetry data and other telemetry data to obtain a plurality of first telemetry data.

[0077] In this embodiment, multiple first telemetry data are obtained based on initial multiple first telemetry data, and the initial multiple first telemetry data are preprocessed to obtain multiple first telemetry data, wherein the initial multiple first telemetry data include target telemetry data, and the target telemetry data include telemetry data before rocket ignition and telemetry data after rocket ignition.

[0078] Optionally, the target telemetry data may be measured by a ground telemetry station at the rocket launch point or a ground telemetry station near the rocket launch point, and the target telemetry data may be divided into first target telemetry data and second target telemetry data, the first target telemetry data being the telemetry data before rocket ignition, and the second target telemetry data being the telemetry data after rocket ignition; since the telemetry data before rocket launch is relatively stable and accurate, the telemetry data before rocket ignition is not processed here, and the second target telemetry data and other telemetry data are merged to obtain a plurality of first telemetry data, and the subsequent rocket telemetry data processing method is executed based on the plurality of first telemetry data.

[0079] Through this embodiment, the telemetry data before rocket ignition is taken out separately, and data processing is performed on the data after rocket ignition, which can effectively reduce the calculation amount of data processing and improve the efficiency of the rocket telemetry data processing method.

[0080] As an optional solution, after splicing multiple target full frames in the order of the frame count list to obtain the second telemetry data, the method further includes:

[0081] S61, concatenating the first target telemetry data and the second telemetry data to obtain third telemetry data.

[0082] After executing the rocket telemetry data processing method based on multiple first telemetry data, the obtained second telemetry data is spliced ​​with the first target telemetry data to obtain third telemetry data. Here, the third telemetry data refers to the telemetry data processed by the rocket telemetry data processing method, which contains complete data before and after the rocket launch.

[0083] Through this embodiment, the first target telemetry data and the second telemetry data are spliced ​​to obtain the third telemetry data, which can improve the integrity of the rocket telemetry data finally obtained.

[0084] Figure 2 This is a second flow chart of the rocket telemetry data processing method provided by the present invention, see Figure 2 , the following describes the method for processing rocket telemetry data in the embodiment of the present application in conjunction with an optional example. In this optional example, the following steps may be included:

[0085] Place all files in the same directory.

[0086] Select a file containing data before and after ignition as data output file A, and obtain the last frame count ID, that is, divide the target telemetry data into first target telemetry data and second target telemetry data, and use the first target telemetry data as data output file A. The first target telemetry data is the telemetry data before rocket ignition, and obtain the frame count list (obtain the last frame count ID).

[0087] All files are read into the buffer queue DataCache according to the full frame, that is, the multiple first telemetry data are read into the buffer area with the full frame as the minimum unit.

[0088] Search for full-frame data with a frame count of FrmeID=FrmeID+1 in DataCache, that is, traverse each frame count in the frame count list, search for full-frame data corresponding to each frame count, and determine a group of full frames to be optimized, wherein each full frame to be optimized in a group of full frames to be optimized is a full frame corresponding to the target frame count in the cache area.

[0089] Take out the full-frame data with the most subframe synchronization words. Here, the full-frame data with the most subframe synchronization words refers to the target full-frame to be optimized. The target full-frame to be optimized is the full-frame to be optimized with the most qualified subframes in a group of full frames to be optimized. The synchronization word of the qualified subframe is equal to the preset expected value.

[0090] Determine whether SysWordNum = number of sub-frames - 1. Here, SysWordNum refers to the number of sub-frame synchronization words in the full-frame data with the most sub-frame synchronization words (the number of qualified sub-frames). The number of sub-frames (sub-frame length) refers to the number of sub-frames in the full-frame. Determine whether SysWordNum is equal to the number of sub-frames - 1.

[0091] If the judgment is yes, the full frame is taken out as the current optimal full frame data, that is, when the number of qualified subframes in the target full frame to be optimized is equal to the preset frame value, the target full frame to be optimized is determined as the target full frame.

[0092] After writing the frame data into file A, it is determined whether it is the last full frame. If it is, it means that all telemetry data have been processed.

[0093] If the judgment is no, obtain the full frame data with the best frame counting quality. For specific steps, see Figure 3 , Figure 3 This is the third flow chart of the method for processing rocket telemetry data provided by the present invention.

[0094] The subframe data with the largest number of subframe synchronizations is searched in the DataCache as the initial frame data, that is, the target full frame to be optimized is determined, and the target full frame to be optimized is the full frame to be optimized (initial frame data) with the largest number of qualified subframes in the group of full frames to be optimized.

[0095] Traverse the i-th subframe frame by frame (i++), that is, traverse each subframe in the target full frame to be optimized.

[0096] Determine whether the current subframe synchronization code is complete, that is, determine whether the number of qualified subframes in the target full frame to be optimized is equal to a preset frame value, wherein the preset frame value is obtained by subtracting 1 from the subframe length of the target full frame to be optimized.

[0097] If the judgment is no, search for subframe data with the optimal subframe synchronization code in other DataCaches, that is, traverse a group of other full frames to be optimized, and obtain a group of replacement subframes to be confirmed from the group of other full frames to be optimized.

[0098] The current subframe data is replaced with the subframe data, that is, when a synchronization word of a to-be-confirmed replacement subframe in a group of to-be-confirmed replacement subframes is equal to a preset expected value, the to-be-confirmed replacement subframe is determined as a target replacement subframe.

[0099] It is determined whether it is the last subframe data, and if it is yes, the method ends.

[0100] Wherein, if the judgment is no, searching for subframe data with the optimal subframe synchronization code in other DataCaches, specifically, the following steps may also be included: Figure 4 This is a fourth flow chart of the method for processing rocket telemetry data provided by the present invention, see Figure 4 .

[0101] The synchronization word is taken out to determine whether the synchronization code is complete, that is, to determine whether the synchronization word of the replacement subframe to be confirmed is equal to a preset expected value.

[0102] When the judgment is yes, the current frame is taken as the subframe data with the best quality.

[0103] If the judgment is no, the synchronization word bit error rate of all subframes is calculated, that is, when there is no synchronization word of the to-be-confirmed replacement subframe in a group of to-be-confirmed replacement subframes equal to the preset expected value, the bit error rate of a group of to-be-confirmed replacement subframes and the target to-be-confirmed subframes is calculated.

[0104] The subframe with the lowest bit error rate is taken out, that is, the subframe data with the best quality is selected, that is, the subframe with the lowest bit error rate in the group of to-be-confirmed replacement subframes and the target to-be-confirmed subframes is selected as the target replacement subframe.
