The invention is described below by referring to preferred implementation steps, and fig. 1 is a flowchart of a method for processing a multi-target spacecraft collaborative association event according to an embodiment of the present application, as shown in fig. 1, the method includes the following steps:
step S101, a multi-target spacecraft collaborative association event criterion table is obtained, the multi-target spacecraft collaborative association 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 comprise a plurality of first telemetry result data frames with a first frame frequency and a plurality of second telemetry result data frames with a second frame frequency.
Specifically, a multi-target spacecraft collaborative association event criterion table is read and divided into two types, wherein the first type is a first frame frequency criterion table (fast frame global section zone criterion table), and the second type is a second frame frequency criterion table (slow frame criterion table). The criterion table comprises information of object codes, data frame frequency, event names, event criterion conditions, continuous judging frame number, global segment zone bit sequence numbers and the like of the telemetering data frames. The first frame rate generally refers to a fast frame, e.g., 512 milliseconds/frame. The second frame rate generally refers to a slow frame, e.g., 1024 milliseconds/frame.
It should be noted that the first frame rate and the second frame rate may be any values according to different application requirements, and are not limited to 512 ms/frame and 1024 ms/frame listed in the above example.
The object code information indicates from which target spacecraft the telemetry data frame originated. The event criterion conditions in the criterion table can have a plurality of groups, but at most, the number of the event criterion conditions does not exceed three groups, and the relation of the criterion conditions is an OR relation, namely, if one group of the criterion meets the condition, the event can be judged to occur. The relation that each criterion condition in the criterion conditions is' and all the criterion conditions in one criterion group are satisfied, then the criterion condition can be judged to be satisfied.
The description of the criterion condition can be written by telemetry parameter code (or global segment flag) + mathematical symbol + numerical value, the mathematical symbol including > (greater than or equal to), > = (greater than or equal to), < (less than or equal to), and < = (equal to or less than). For example, VGNz032 < 1.0 indicates that the resulting value of the telemetry parameter code VGNz032 is less than 1.0. The continuous judging frame number is used for preventing the misjudgment and the missed judgment of the event, and the occurrence of the event is judged only when the continuous judging frame number is 3, for example, and the data frames of the continuous 3 frames of the telemetering processing result meet the criterion condition. The global segment zone bits can be used as criterion conditions, and description of the multi-target spacecraft association criterion is realized by using the serial numbers of the global segment zone bits.
Obtaining a plurality of telemetry result data frames of a plurality of target spacecraft, wherein the frame format of the telemetry result data frames can be in the following form:
L＝{(M 1 ：X 1 )，(M 2 ：X 2 )，(M 3 ：X 3 )…(M n ：X n )}
where n represents the number of telemetry parameters, M i Code number, X, representing the ith telemetry parameter i Represents M i The corresponding result value. The data frame can be described by using an XML format, the description field comprises a data frame time mark, an object code, a frame frequency, a parameter number, a parameter code number and a result value of the parameter code number, and the parameter code number and the result value corresponding to the parameter code number appear in pairs.
Step S102, a global segment flag bit 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, wherein the global segment flag bit is used for representing whether the first target event occurs or not.
Specifically, event judgment is carried out according to the fact that the target codes described in the multi-target spacecraft collaborative correlation event criterion table are automatically matched with the corresponding telemetry data frames of the target spacecraft. And if the frame is the telemetry result data frame with the first frame frequency, judging whether the frame telemetry data meets the criterion condition in the criterion table according to the first frame frequency criterion table. If the global segment flag is satisfied, setting the corresponding state global segment flag to be 1 (the initial state of the flag bit is 0,0 represents that the event is not judged, and 1 represents that the event is judged), and if the criterion condition is not satisfied, acquiring the telemetry result data frames of the target spacecrafts again.
And step S103, determining whether a second target event occurs according to the criterion condition in the second frame frequency criterion table, the second telemetering result data frame and the global segment flag bit of the first target event.
Specifically, the global segment flag bit is read, and whether the second frame frequency telemetry data meets the criterion condition in the slow frame criterion table or not is judged by combining the global segment flag bit. If the criterion condition is met, the event occurs, a judgment result is output, and if the criterion condition is not met, the telemetering result data frames of the target spacecrafts are acquired.
And step S104, if a second target event occurs, representing that the multi-target spacecraft collaborative association event occurs.
In summary, the state change condition of the spacecraft at the first frame frequency is obtained through the first frame frequency criterion table, and the global segment flag bit is used for state recording. And judging the spacecraft state of the second frame frequency through a second criterion table by combining the global segment zone bits, thereby realizing accurate interpretation of the multi-target spacecraft collaborative association event and improving the efficiency of judging the multi-target spacecraft collaborative association event.
In the processing method for the multi-target spacecraft collaborative association event provided by the embodiment of the application, the first frame frequency criterion table and the second frame frequency criterion table are composed of target codes, frame frequencies, event names, criterion conditions, continuous judging frame numbers and global segment flag bit serial numbers, wherein the target codes correspond to the target spacecrafts one to one.
Specifically, the criterion table includes information such as telemetry data frame object code, data frame frequency, event name, event criterion condition, continuous judgment frame number, and global segment flag bit sequence number. The first frame rate generally refers to a fast frame, e.g., 512 milliseconds/frame. The second frame rate generally refers to a slow frame, e.g., 1024 milliseconds/frame. The object code indicates from which target spacecraft the telemetry data frame originated. The event criterion conditions in the criterion table can have a plurality of groups, but at most, the number of the event criterion conditions does not exceed three groups, and the relation of the criterion conditions is an OR relation, namely, if one group of the criterion meets the condition, the event can be judged to occur. And after each criterion condition in the criterion conditions is in an 'and' relationship and all the criterion conditions in one criterion group are met, judging that the criterion condition is met.
The description of the criterion condition adopts the writing method of telemetry parameter code (or global segment zone bit) + mathematical symbol + numerical value, the mathematical symbol includes = (greater than number), = (greater than or equal to number), < (less than number), = (less than or equal to number), and = (equal to number). For example, VGNz032 < 1.0 indicates that the resulting value of the telemetry parameter code VGNz032 is less than 1.0. The continuous judging frame number is used for preventing the misjudgment and the missed judgment of the event, and the occurrence of the event is judged only when the continuous judging frame number is 3, for example, and the data frames of the continuous 3 frames of the telemetering processing result meet the criterion condition. The global segment zone bits can be used as criterion conditions, and description of the multi-target spacecraft association criterion is realized by using the serial numbers of the global segment zone bits.
The description of the criterion conditions of the multi-target spacecraft collaborative association event is flexibly realized through the criterion table, the criterion table can clearly express the judgment conditions and the logic relation of the association event, the fusion processing of subsequent data is facilitated, and meanwhile, the manual maintenance efficiency can be improved.
How to obtain the global segment flag bit according to the first frame frequency criterion table is crucial, and in the processing method of the multi-target spacecraft collaborative association event provided in the embodiment of the application, the global segment flag bit 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 is defined as follows: selecting a telemetry result data frame corresponding to a first object code from the plurality of first telemetry result data frames according to the first object code in the first frame frequency criterion table; and judging according to the telemetry result data frame corresponding to the first target code and the criterion condition in the first frame frequency criterion table to obtain the global segment zone bit of the first target event.

Reading the continuous judging frame number in a first frame frequency criterion table, and determining the judging frame number N, wherein the continuous judging frame number in the first frame frequency criterion table is the same as N; and continuously judging whether the result value corresponding to the first telemetry parameter code in the telemetry result data frame corresponding to the first object code of the N frames meets the criterion condition in the first frame frequency criterion table.
Specifically, a first target code is obtained through a first frame frequency criterion table, the remote sensing data of which spacecraft is judged is determined, and a remote sensing result data frame corresponding to the first target code is selected from a plurality of first remote sensing result data frames through the first target code. And then reading a first telemetry parameter code used by the criterion condition in the criterion group through a first frame frequency criterion table, and obtaining a result value corresponding to the first telemetry parameter code from a telemetry result data frame corresponding to the first object code through the first telemetry parameter code. And finally, judging whether the result value corresponding to the first telemetering parameter code meets the criterion condition in the first frame frequency criterion table. If the criterion condition is met, setting the corresponding global segment flag bit to be a first preset numerical value (for example, "1") according to the global segment flag bit sequence number corresponding to the first target event. In order to avoid the occurrence of false judgment or missed judgment, continuous judgment is performed according to the continuous judging frame number, for example, if the continuous judging frame number is 3, whether a result value corresponding to a first telemetry parameter code in a telemetry result data frame corresponding to a first object code of the 3 frames meets a criterion condition in a first criterion table is continuously judged.
It should be noted that the global segment flag bit sequence number and the global segment flag bit may be stored in the global segment flag bit file.
In an alternative embodiment, the following algorithm may be used to achieve the state of the target spacecraft for the first frame rate:
input: a first frame frequency criterion table S, a first telemetering result data frame L and a global segment zone bit file G

Specifically, if the result value corresponding to the first telemetry parameter code does not meet the criterion condition in the first frame rate 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 acquisition of the telemetry result data frames of the plurality of target spacecrafts is performed again.
