Their work processes are correlated with each other, and their states are tightly coupled. For ground flight control monitoring personnel, not only do they need to monitor the state of a single spacecraft, but also need to jointly monitor multiple spacecrafts to comprehensively monitor the state and comprehensively interpret the correctness of the cooperative working state of the spacecrafts. Comprehensive state monitoring of multi-target spacecrafts is an important means to improve the reliability and safety of spacecraft flight control tasks, and the interpretation of multi-target spacecraft cooperative correlation events is the basis for realizing the operation state monitoring of multi-target spacecraft cooperation.

[0003] The interpretation of multi-target spacecraft cooperative correlation events has the following difficulties: the state of a spacecraft is judged by telemetry data transmitted by the spacecraft. To implement multi-target spacecraft cooperative correlation event interpretation, the telemetry data of multiple spacecrafts needs to be collected for comprehensive processing. The time reference of telemetry data collection of each spacecraft is different, the code rate of transmission is different, and the state interpretation sequence is also different. In the prior art, when judging multi-target spacecraft cooperative correlation events, each target spacecraft event state is judged separately, and then the correlation event state is obtained.

[0029] It should be noted that the embodiments and features of the embodiments in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0030] In order to enable persons skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by persons skilled in the art without creative labor should fall within the scope of protection of the present application.

[0031] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented. In addition, the terms "comprise" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device comprising a series of steps or units does not necessarily limit to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0032] The present application will be described below in conjunction with preferred implementation steps, Figure 1 is a flowchart of a processing method of a multi-target spacecraft cooperative correlation event according to an embodiment of the present application, as shown in the figure, the method comprises the following steps: Figure 1

[0033] Step S101, obtaining a multi-target spacecraft cooperative correlation event criterion table and obtaining a plurality of telemetry result data frames of a plurality of target spacecraft, wherein the multi-target spacecraft cooperative correlation event criterion table is composed of a first frame frequency criterion table and a second frame frequency criterion table, and the plurality of telemetry result data frames at least include a plurality of first frame frequency first telemetry result data frames and a plurality of second frame frequency second telemetry result data frames.

[0034] ​Specifically, a multi-target spacecraft cooperative correlation event criterion table is read, which is divided into two types of tables. The first type is a first frame frequency criterion table (fast frame global segment flag criterion table), and the second type is a second frame frequency criterion table (slow frame criterion table). The criterion table includes target code, data frame frequency, event name, event criterion condition, continuous discrimination frame number, global segment flag sequence number and the like of a telemetry data frame. The first frame frequency generally refers to a fast frame, for example, 512 ms / frame. The second frame frequency generally refers to a slow frame, for example, 1024 ms / frame.

[0035] It should be noted that the first frame frequency and the second frame frequency described above can be any value according to different application requirements, and are not limited to 512 ms / frame and 1024 ms / frame listed in the above examples.

[0036] The target code information indicates that the telemetry result data frame is from which target spacecraft. The criterion condition in the criterion table can have multiple groups, but the number of criterion groups is not more than three. The relationship of the criterion conditions is an "or" relationship, that is, the event can be judged to occur when one criterion group meets the condition. Each criterion condition in the criterion condition is an "and" relationship, and all criterion conditions in one criterion group meet the criterion condition.

[0037] The criterion condition can be described by using a telemetry parameter code (or a global segment flag) + a mathematical symbol + a value. The mathematical symbol includes > (greater than), >= (greater than or equal to), < (less than), <= (less than or equal to), and = (equal to). For example, VGNz032 < 1.0 indicates that the result value of the telemetry parameter code VGNz032 is less than 1.0. The continuous discrimination frame number is used to prevent event misjudgment and omission. Taking the continuous discrimination frame number as 3 as an example, the telemetry processing result data frame needs to meet the criterion condition for 3 consecutive frames to judge that the event occurs. The global segment flag can be used as a criterion condition, and the global segment flag sequence number is used to realize the description of the multi-target spacecraft correlation criterion.

[0038] A plurality of telemetry result data frames of a plurality of target spacecrafts are obtained. The frame format of the telemetry result data frame can adopt the following form:

[0039] L = {(M1: X1), (M2: X2), (M3: X3)…(Mn: Xn)} n : X n )

[0040] Wherein, n represents the number of telemetry parameters, Mi represents the code of the i-th telemetry parameter, Xi represents the value of the i-th telemetry parameter, and M represents the telemetry parameter code. i i i ​​Corresponding result value. The data frame can be described using an XML format, and the description fields include a data frame time stamp, a target code, a frame frequency, a number of parameters, a parameter code, and a result value corresponding to the parameter code.

[0041] In step S102, a global segment flag bit of the first target event is obtained according to a criterion condition in the first frame frequency criterion table and the first telemetry result data frame, wherein the global segment flag bit is used to represent whether the first target event occurs.

[0042] Specifically, the telemetry data frame of the corresponding target spacecraft is automatically matched according to the target code described in the multi-target spacecraft cooperative correlation event criterion table, and event judgment is performed. If the telemetry result data frame is of the first frame frequency, whether the frame telemetry data satisfies the criterion condition in the first frame frequency criterion table is judged. If yes, the corresponding state global segment flag is set to 1 (the initial state of the flag bit is 0, 0 represents that the event is not judged out, and 1 represents that the event is judged out), and if no, the telemetry result data frames of the multiple target spacecrafts are acquired again.

[0043] In step S103, whether the second target event occurs is determined according to the criterion condition in the second frame frequency criterion table, the second telemetry result data frame, and the global segment flag bit of the first target event.

[0044] Specifically, the global segment flag bit is read, and whether the second frame frequency telemetry data satisfies the criterion condition in the slow frame criterion table is judged in combination with the global segment flag bit. If yes, the event occurs, and the judgment result is output, and if no, the telemetry result data frames of the multiple target spacecrafts are acquired.

[0045] In step S104, if the second target event occurs, it is represented that the multi-target spacecraft cooperative correlation event occurs.

[0046] As described above, the state change of the spacecraft of the first frame frequency is obtained through the first frame frequency criterion table, and the state is recorded using the global segment flag bit. The spacecraft state of the second frame frequency is judged through the second criterion table in combination with the global segment flag bit, so that the multi-target spacecraft cooperative correlation event is accurately interpreted, and the efficiency of the judgment of the multi-target spacecraft cooperative correlation event is improved.

[0047] In the multi-target spacecraft cooperative correlation event processing method provided in the embodiments of the present application, the first frame frequency criterion table and the second frame frequency criterion table are composed of a target code, a frame frequency, an event name, a criterion condition, a continuous discrimination frame number, and a global segment flag bit serial number, wherein the target code is one-to-one corresponding to the target spacecraft.

[0048] Specifically, the criterion table includes information such as a telemetry data frame target code, a data frame frequency, an event name, an event criterion condition, a continuous discrimination frame number, and a global segment flag sequence number. The first frame frequency generally refers to a fast frame, for example, 512 ms / frame. The second frame frequency generally refers to a slow frame, for example, 1024 ms / frame. The target code indicates that the telemetry data frame is from which target spacecraft. The event criterion condition in the criterion table can have multiple groups, but the number of groups is not more than three criteria. The relationship of the criterion conditions is an "or" relationship, that is, the event can be judged to occur when one group of criteria meets the condition. Each criterion condition in the criterion condition is an "and" relationship, and all criterion conditions in a criterion group meet the criterion condition, and then the criterion condition is determined to be true.

[0049] The criterion condition is described by using a telemetry parameter code (or a global segment flag) + a mathematical symbol + a numerical value. The mathematical symbol includes > (greater than), >= (greater than or equal to), < (less than), <= (less than or equal to), and = (equal to). For example, VGNz032 < 1.0 indicates that the result value of the telemetry parameter code VGNz032 is less than 1.0. The continuous discrimination frame number is used to prevent event misjudgment and missed judgment. Taking the continuous discrimination frame number as 3 as an example, the telemetry processing result data frame needs to meet the criterion condition for 3 consecutive frames, and then the event is determined to occur. The global segment flag can be used as a criterion condition, and the global segment flag sequence number is used to realize the description of the correlation criterion of multiple target spacecrafts.

[0050] The criterion table flexibly realizes the description of the correlation criterion condition of the multiple target spacecraft cooperative events, and clearly expresses the judgment condition and the logical relationship of the correlation event. The criterion table not only facilitates subsequent data fusion processing, but also improves the efficiency of manual maintenance.

[0051] How to obtain the global segment flag according to the first frame frequency criterion table is crucial. In the method for processing the multiple target spacecraft cooperative events provided in the embodiment of the application, the global segment flag of the first target event is obtained according to the criterion condition in the first frame frequency criterion table and the first telemetry result data frame, and the following is limited: a telemetry result data frame corresponding to the first target code is selected from multiple first telemetry result data frames according to the first target code in the first frame frequency criterion table; and the global segment flag of the first target event is obtained by judging the telemetry result data frame corresponding to the first target code and the criterion condition in the first frame frequency criterion table.

[0052] read the first telemetry parameter code of the criterion condition in the first frame frequency criterion table, and obtain the result value corresponding to the first telemetry parameter code from the telemetry result data frame corresponding to the first target code according to the first telemetry parameter code; determine whether the result value corresponding to the first telemetry parameter code meets the criterion condition in the first frame frequency criterion table; if the result value corresponding to the first telemetry parameter code meets the criterion condition in the first frame frequency criterion table, it indicates that the first target event occurs; set the global segment flag to a first preset value according to the global segment flag sequence number corresponding to the first target event, wherein the first preset value indicates that the first target event occurs.

[0053] read the continuous discrimination frame number in the first frame frequency criterion table, and determine the judgment frame number N, wherein the continuous discrimination frame number in the first frame frequency criterion table is the same as N; determine whether the result value corresponding to the first telemetry parameter code in the telemetry result data frame corresponding to the first target code meets the criterion condition in the first frame frequency criterion table.

[0054] Specifically, the first target code is obtained through the first frame frequency criterion table, and it is determined which spacecraft remote sensing data is to be judged. The telemetry result data frame corresponding to the first target code is selected from a plurality of first telemetry result data frames through the first target code. Then the first telemetry parameter code used in the criterion condition in the criterion group in the first frame frequency criterion table is read, and the result value corresponding to the first telemetry parameter code is obtained from the telemetry result data frame corresponding to the first target code through the first telemetry parameter code. Finally, it is determined whether the result value corresponding to the first telemetry parameter code meets the criterion condition in the first frame frequency criterion table. If the criterion condition is met, the corresponding global segment flag is set to a first preset value (for example, "1") according to the global segment flag sequence number corresponding to the first target event. In order to avoid misjudgment or missed judgment, continuous judgment is performed according to the continuous discrimination frame number, for example, if the continuous discrimination frame number is 3, it is determined whether the result value corresponding to the first telemetry parameter code in the telemetry result data frame corresponding to the first target code meets the criterion condition in the first criterion table.

[0055] It should be noted that the global segment flag sequence number and the global segment flag can be stored in a global segment flag file.

[0056] In an optional embodiment, the following algorithm can be used to realize the state of the target spacecraft of the first frame frequency:

[0057] Input: first frame frequency criterion table S, first telemetry result data frame L, global segment flag file G

[0058] Output: global segment flag Gnum

[0059] T = total number of all items in the fast frame global segment flag criterion table

[0060] 1. for interation 1 to T do;

[0061] 2. for interation 1 to criterion group (A, B, C) do;

[0062] 3. read the telemetry parameter code used in the criterion condition in the criterion group;

[0063] 4. find the parameter code in L, and obtain the parameter result value;

[0064] 5. judge whether the parameter result value meets the criterion condition;

[0065] 6. if the criterion condition is met;

[0066] 7. Gnum = 1;

[0067] 8. output Gnum;

[0068] 9. end for.

[0069] In summary, the criterion table can clearly express the judgment conditions and logical relationships of the associated events, and improve the accuracy of the judgment of the associated cooperative events.

[0070] If the result value corresponding to the first telemetry parameter code does not meet the criterion condition in the first frame frequency criterion table, the global segment flag is set to a second preset value according to the global segment flag serial number corresponding to the first target event, wherein the second preset value represents that the first target event does not occur.

[0071] Specifically, if the result value corresponding to the first telemetry parameter code does not meet the criterion condition in the first frame frequency criterion table, the global segment flag is set to a second preset value (for example, “0”), the first target event does not occur, and the telemetry result data frame of the plurality of target spacecrafts is obtained again.

[0072] The second telemetry result data frame is judged in the following manner: a second target code and a global segment flag bit of a first target event in a second frame frequency criterion table are obtained; a telemetry result data frame corresponding to the second target code is selected from the second telemetry result data frame according to the second target code in the second frame frequency criterion table; a second telemetry parameter code of a criterion condition in the second frame frequency criterion table is read, and a result value corresponding to the second telemetry parameter code is obtained from the telemetry result data frame corresponding to the second target code according to the second telemetry parameter code; whether the result value corresponding to the second telemetry parameter code satisfies the criterion condition in the second frame frequency criterion table is judged, and whether the global segment flag bit of the first target event is a first preset value is judged; if the result value corresponding to the second telemetry parameter code satisfies the criterion condition in the second frame frequency criterion table, and the global segment flag bit of the first target event is the first preset value, it is indicated that the second target event occurs.

[0073] Specifically, the target code is obtained through the second frame frequency criterion table, it is determined which spacecraft the remote sensing data is judged, and the telemetry result data frame corresponding to the second target code is selected from the second telemetry result data frame through the target code. Then the second telemetry parameter code used by the criterion condition in the criterion group is read through the first frame frequency criterion table, and the result value corresponding to the second telemetry parameter code is obtained from the telemetry result data frame corresponding to the second target code through the second telemetry parameter code. Finally, whether the result value corresponding to the second telemetry parameter code satisfies the criterion condition in the second frame frequency criterion table, and whether the corresponding global segment flag bit is the first preset value are judged. If the criterion condition is satisfied and the global segment flag bit is the first preset value, it is indicated that the second target event occurs, and then the multi-target spacecraft cooperative correlation event occurs. Similarly, in order to avoid misjudgment or omission, continuous judgment is performed according to the number of continuous discrimination frames, for example, if the number of continuous discrimination frames is 3, whether the result value corresponding to the second telemetry parameter code in the telemetry result data frame corresponding to the second target code in 3 frames is satisfied is continuously judged.

[0074] In an optional embodiment, the following algorithm can be used to realize the state of the target spacecraft of the second frame frequency:

[0075] Input: second frame frequency criterion table D, second telemetry result data frame L, global segment flag bit file G

[0076] Output: correlation event occurrence result R

[0077] T = total number of all items in the second frame frequency criterion table

[0078] Gnum = global segment flag bit

[0079] 1. for iteration 1 to T do;

[0080] 2. for interation 1 to criterion group (A, B, C) do;

[0081] 3. Get the telemetry parameter code and Gnum used in the criterion condition in the criterion group;

[0082] 4. Find the parameter code in L, get the parameter result value;

[0083] 5. Find the Gnum in G, get the flag result value;

[0084] 6. Combine the parameter result value and the flag result value, judge whether the criterion condition is satisfied;

[0085] 7. if the criterion condition is satisfied;

[0086] 8. R = 1;

[0087] 9. Output R (correlation event name);

[0088] 10. end for.

[0089] In an optional embodiment, the multi-target table spacecraft cooperative event judgment flow is as shown in Figure 2 : Take the establishment of the air-to-air communication machine communication correlation event in the spacecraft A and spacecraft B implementation of the rendezvous and docking process as an example, and explain how to judge the correlation event.

[0090] The criterion condition is determined, the spacecraft telemetry parameters used in the correlation event criterion condition are selected, the criterion condition is determined according to the flight control flow during the spacecraft task execution and combined with the expert experience knowledge, the telemetry data selection is determined, the telemetry parameters used are different for different correlation event criterion conditions. In this embodiment, the spacecraft A selects the telemetry parameter VGNz032, the spacecraft B selects the telemetry parameter IGNx075, and the criterion of the air-to-air communication machine communication establishment correlation event is VGNz032>3.2 and IGNx075>1.0.

[0091] The frame frequency of the telemetry data frame of the spacecraft A and the spacecraft B is judged, and the processing time sequence relationship of the telemetry data frame with different frame frequencies is as shown in Figure 3The state results of the telemetry data with fast frame frequency are stored, and the stored state record results can be used as a criterion condition in the process of the telemetry data with slow frame frequency (i.e., the global segment flag described above). The telemetry data frame frequency of the spacecraft A is 512 ms / frame, and the telemetry data frame frequency of the spacecraft B is 1024 ms / frame. The telemetry criterion of the spacecraft A is described by using a fast frame criterion table (corresponding to the first frame frequency criterion table described above), and the telemetry criterion of the spacecraft B is described by using a slow frame criterion table (i.e., the second frame frequency criterion table described above). The results are shown in Table 1 and Table 2. In Table 2, the "global segment flag" G1 in Table 1 is cited as a telemetry criterion condition of the spacecraft B. Through the description of the multi-target spacecraft cooperative correlation event criterion table, the criterion VGNz032>3.2 and IGNx075>1.0 are equivalent to G1=1 and IGNx075>1.0.

[0095]

[0096] 1. After the multi-target spacecraft cooperative correlation event criterion table is established, it is read into the flow shown in the figure. Figure 2

[0097] 2. The spacecraft telemetry result data frame is input. In this embodiment, there are two target data frames of the spacecraft A and the spacecraft B, and the data frames are continuously input into the flow according to their frame frequencies.

[0098] 3. The target code of the spacecraft to which the telemetry data frame belongs and the telemetry frame frequency are identified.

[0099] 4. The telemetry data frame of the corresponding spacecraft is automatically matched and processed according to the target code described in the correlation event criterion table. In the processing flow of this embodiment, the data frame of the spacecraft A is processed by using the fast frame global segment flag criterion table shown in Table 1, and the data frame of the spacecraft B is processed by using the slow frame criterion table shown in Table 2. The target code 5628 in Table 1 represents the spacecraft A, and the target code 5799 in Table 2 represents the spacecraft B. The spacecraft target code can be self-defined.

[0100] ​In this example, the telemetry result value corresponding to IGNx075 is 1.1, the global segment flag G1 = 1, the criterion G1 = 1 and IGNx075 > 1.0 is satisfied, it is judged that the associated event "air-to-air communication machine communication establishment" occurs, and the result is output.

[0101] It should be noted that the method for processing the cooperative associated event of the multi-target spacecraft provided in the present application is not limited to the cooperative associated event judgment of two target spacecrafts, but can also be used to process the cooperative associated event judgment of multiple target spacecrafts. For example, the cooperative associated event of spacecraft A, spacecraft B and spacecraft C is judged, the state of spacecraft A is first judged, the state of spacecraft B is determined based on the state of spacecraft A, and the state of spacecraft C is determined based on the state of spacecraft B, and finally it is determined whether the cooperative associated event of spacecraft A, spacecraft B and spacecraft C occurs. Among them, the method for determining the state of spacecraft C based on the state of spacecraft B is the same as the method for determining the state of spacecraft B based on the state of spacecraft A, so it is not repeated here.

The state change of the spacecraft with the first frame frequency is obtained by the first frame frequency criterion table and the global segment flag is used for state recording. In combination with the global segment flag, the spacecraft state with the second frame frequency is judged by the second criterion table, so as to realize accurate reading of the multi-target spacecraft cooperative associated event, and thus the efficiency of the judgment of the multi-target spacecraft cooperative associated event is improved.
