TECHNICAL FIELD
[0001] Embodiments of the present specification relate to the technical field of spacecraft magnetic control, and in particular to a spacecraft full-process magnetic control method. BACKGROUND
[0002] Space magnetic field detection is one of the important tasks of spacecrafts at home and abroad. In order to make the magnetometer carried measure high-precision space magnetic field data, the spacecraft magnetic property must be controlled to reduce the magnetic field interference of the spacecraft itself on the magnetometer. Because the satellite magnetic property source and change are very complex, the spacecraft magnetic control implementation is extremely difficult. At present, the spacecraft magnetic control has become the core work of the development of space magnetic field detection spacecraft.
[0003] The development stage of the spacecraft can be divided into four stages in turn, namely, demonstration, scheme, preliminary sample and final sample. In order to achieve the expected magnetic control index, the most reliable magnetic control method is to start from the spacecraft demonstration stage and carry out corresponding magnetic control work in the spacecraft demonstration, scheme, preliminary sample and final sample stages.
[0004] Briefly speaking, magnetic control is to divide the whole spacecraft magnetic control index into the magnetic control index of each single machine according to the task proposed magnetic control index, and different index decomposition and calculation algorithms are used in different stages. Through the full implementation of the single machine index, the magnetic control index of the whole spacecraft is realized. Therefore, determining the magnetic control index of each single machine is a very important work link and content of the magnetic control work, which involves the whole stage and the whole process of the spacecraft. If the single machine index decomposition is too strict, the single machine cannot complete the index, and if the decomposition is too loose, the final whole spacecraft magnetic control index cannot meet the task requirements. At the same time, the single machine magnetic control index is an important input and constraint condition for the development of each single machine, which needs to be dynamically adjusted in different stages. Therefore, the determination algorithm of the single machine index in different stages is very important. Therefore, a scientific, reasonable and feasible spacecraft full-process magnetic control method with single machine magnetic control index decomposition and calculation algorithm as the core is needed.
[0005] At present, there is no related scheme, and therefore, a magnetic control scheme is urgently needed. SUMMARY

[0051] In the specification, a spacecraft full-process magnetic control method is provided, and the specification also relates to a spacecraft full-process magnetic control device, a computing device, and a computer-readable storage medium, which are described in detail one by one in the following embodiments.
[0052] Referring to Figure 1 , Figure 1 A flowchart of a spacecraft full-process magnetic control method according to one embodiment of the specification is shown, which specifically includes the following steps.
[0053] Step 101: Obtain a single-machine list, determine a demonstration single-machine magnetic control index based on the single-machine list, and determine a demonstration whole-machine magnetic control index based on the demonstration single-machine magnetic control index.
[0054] In one possible implementation, determining the demonstration single-machine magnetic control index based on the single-machine list includes: determining at least two single machines based on the single-machine list, obtaining historical data of the single machines, and determining the demonstration single-machine magnetic control index based on the historical data.
[0055] In practical application, the index decomposition needs to be estimated according to the magnetism of the single machine. After all the single machines of the spacecraft are demonstrated, first, according to the single machine list, the magnetic measurement data of the similar single machine products with the same technical state are searched to serve as the magnetic control index of each single machine. Some single machine indexes are represented by magnetic moment M , such as the single machine of the platform part. Some single machine magnetic control indexes are represented by magnetic field B , such as the solar wing, heating circuit, cable network and the like.
[0056] For example, the star computer of a spacecraft needs to be allocated a magnetic control index. The test results of the star computer that has been tested for magnetism in the past can be searched. If the two star computer models are consistent, the reliability of the historical test data is very high, and the historical data can be directly decomposed into the index.
[0057] In a possible implementation, the single machine magnetic control index is determined based on the single machine list, including: in the case that the single machine does not have historical data, the single machine is decomposed to determine at least two modules; the module historical data of the at least two modules is acquired, and the module historical data is accumulated to determine the single machine magnetic control index.
[0058] In practical application, if a single machine is a new research product and there is no similar single machine in the past, the single machine can be decomposed into multiple modules, such as main structural material, screw, shaped motor and the like, and then the historical data is searched. The magnetism of each module is accumulated to serve as the index. The accumulation method overestimates the magnetism of the single machine, but the estimated magnetism of the single machine in the demonstration stage is allowed.
[0059] Step 102: based on the demonstration of the whole machine magnetic control index and the demonstration of the whole machine magnetic requirement, adjusting the single machine magnetic control index determination scheme to determine the single machine magnetic control index.
[0060] In a possible implementation, the single machine magnetic control index is determined based on the demonstration of the whole machine magnetic control index, including: determining the magnetic moment data of each direction corresponding to each single machine; determining the total magnetic moment based on the magnetic moment data in each direction; determining the magnetic field data by the dipole method based on the total magnetic moment, and determining the demonstration of the whole machine magnetic control index based on the magnetic field data.
[0061] In practical application, in the demonstration stage, the magnetism of each single machine is obtained through the above work. Since the direction of the magnetism of each single machine is unknown, the following statistical algorithm is adopted:
[0062] For the magnetic moment M (m x , m y , m zThe single machine representing the index, assuming a total of m, the magnetic moment of the three directions of the single machine is estimated according to the maximum absolute value of the three-axis magnetic moment, that is, the magnetic moment of each single machine is estimated as:
[0063]
[0064] The total magnetic moment of the single machines is:
[0065]
[0066] Since the total index of the spacecraft magnetic control is generally in the form of a magnetic field, the magnetic moment index needs to be converted into a magnetic field index, and the conversion formula is the dipole method formula:
[0067]
[0068] Wherein, r is the position vector of the target calculation point relative to the center of all single machines.
[0069] For the single machine represented by the magnetic field B , assuming a total of n, the serial numbers are 2, 3, 4,..., n+1.
[0070] The statistical calculation formula of the magnetic control index of the whole machine is:
[0071]
[0072] At this time B t is the magnetic control index that the spacecraft can achieve in the demonstration stage, and the magnetic properties of each single machine in the above formula can be regarded as the magnetic control index of each single machine.
[0073] Step 103: Determine the scheme whole machine magnetic control index based on the scheme single machine magnetic control index, and adjust the scheme single machine magnetic control index based on the scheme magnetic control index and the scheme whole machine magnetic property requirement to determine the preliminary sample single machine magnetic control index.
[0074] In one possible implementation, determining the scheme whole machine magnetic control index based on the scheme single machine magnetic control index includes: determining the scheme total magnetic moment based on the scheme single machine magnetic control index; determining the scheme magnetic field data based on the conversion of the scheme total magnetic moment; and determining the scheme whole machine magnetic control index based on the scheme magnetic field data and the normal distribution.
[0075] In actual application, for spacecraft magnetic control work, the biggest difference between the scheme stage and the demonstration stage is that the single machine composition is basically determined in the scheme stage, and the position and direction of each single machine are roughly determined, so it is not necessary to estimate according to the maximum value. The magnetic control index of all single machines of the spacecraft is directly determined according to the historical test data M i or B i .
[0076] In the scheme phase, the following statistical algorithm can be taken:
[0077] For the single machine whose index is represented by magnetic moment M , assuming there are m machines, the total magnetic moment of these machines is:
[0078]
[0079] For the single machine whose index is represented by magnetic field B , assuming there are n machines, the serial numbers are 2, 3, 4,..., n+1. Since each single machine is basically independent of each other, the magnetic field generated by each single machine is also independent of each other. At this time, the magnetic field generated by the single machine basically conforms to the standard normal distribution, and the statistical calculation formula of the magnetic control index of the whole machine is:
[0080]
[0081] At this time B t is the magnetic control index that the spacecraft can achieve in the scheme phase. The magnetic properties of each single machine in the above formula can be taken as the magnetic control index of each single machine.
[0082] Step 104: Based on the initial sample single machine magnetic control index, a magnetic test is carried out to determine the test result, and based on the test result and the initial sample whole machine magnetic property requirement, the initial sample single machine magnetic control index is adjusted to determine the positive sample single machine magnetic control index.
[0083] In one possible implementation, based on the test result and the initial sample whole machine magnetic property requirement, the initial sample single machine magnetic control index is adjusted to determine the positive sample single machine magnetic control index, including: based on the test result, statistical simulation is carried out to determine the initial sample total magnetic moment; based on the initial sample total magnetic moment, the initial sample whole machine magnetic control index is determined, and based on the initial sample whole machine magnetic control index and the initial sample whole machine magnetic property requirement, the initial sample single machine magnetic control index is adjusted to determine the positive sample single machine magnetic control index.
[0084] In actual application, in the initial sample stage, the positions and directions of each single machine of the spacecraft are basically determined. Each single machine will develop an initial sample product, at this time, the real magnetic properties of all single machines can be obtained through a magnetic test M i or B i . At this time, for the single machine whose index is represented by magnetic moment M , assuming there are m machines, the total magnetic moment of these machines is M t The statistical simulation can be carried out by an accurate simulation method.
[0085] For the single machine whose index is represented by magnetic field B , assuming there are n machines, the serial numbers are 2, 3, 4,..., n+1.
[0086] The whole device magnetic control index statistical calculation formula is consistent with the scheme stage, and is also:
[0087]
[0088] At this time B t That is, the spacecraft can reach the magnetic control index in the prototype stage, and the magnetic properties of each single machine in the above formula can be used as the magnetic control index of each single machine.
[0089] In one possible implementation, based on the prototype whole device magnetic control index and the prototype whole machine magnetic property requirement, the prototype single machine magnetic control index is adjusted to determine the positive sample single machine magnetic control index, including: in the case that the prototype whole device magnetic control index does not meet the prototype whole machine magnetic property requirement, reducing the prototype single machine magnetic control index to determine the target single machine; based on the target single machine, a magnetic test is performed to determine the positive sample single machine magnetic control index.
[0090] In actual application, after the prototype stage of development, part of the single machine exceeds the index requirement, and then leads to the whole device index exceeding the standard, at this time, the single machine manufacturer can be proposed to reduce the single machine magnetic property by replacing low magnetic material, cable layout design, magnetic compensation, magnetic shielding, low magnetic leakage design, etc.
[0091] Step 105: determining the positive sample whole device magnetic control index based on the positive sample single machine magnetic control index.
[0092] In actual application, the single machine after modification must be tested again to obtain the real magnetic property of all single machines M i Or B i Finally, the positive sample single machine product produced is tested one by one, and the integration assembly work is carried out after meeting the index requirement.
[0093] For the single machine whose index is represented by magnetic moment M The total magnetic moment of the single machine cannot be obtained by statistics, but should be obtained by actual test M t .
[0094] For the single machine whose index is represented by magnetic field B There are n in total, and the serial numbers are 2, 3, 4,..., n+1.
[0095] The whole device magnetic control index statistical calculation formula is consistent with the scheme stage, and is also:
[0096]
[0097] At this time B tThat is the spacecraft in the final reaches of the magnetic control index, is the final result of the magnetic control work.
[0098] In an embodiment, in a certain satellite actual magnetic control process, the magnetic control task index is 0.5nT, the satellite carries out the magnetic control work according to the embodiment of the present specification, and finally controls the magnetic control to 0.33nT, which is better than the index requirement.
[0099] It should be noted that if the spacecraft magnetic control method is not a full-process magnetic control, but directly from the positive sample stage, once the single machine product produced by it exceeds the index, if the rectification is carried out, the rectification cost is large and the progress is delayed, if the rectification is not carried out, the spacecraft factory index can only be compromised, which affects the spacecraft task quality or causes the spacecraft life to decrease.
[0100] If the index decomposition algorithm is too strict in each stage, such as all according to the algorithm of the positive sample stage, it will lead to the work cannot be carried out because there is no real data, and it may also lead to the expected index value is too low, which brings great difficulty to the subsequent work, and easily leads to the index out of control. If the index decomposition algorithm is too loose, such as all according to the algorithm of the demonstration stage, it will lead to the index estimation value is too high, deviating from the actual situation.
[0101] The embodiment of the present specification gives a full-process phased magnetic control work guidance scheme, by executing different index decomposition algorithms, the spacecraft manufacturer can be guided to understand the magnetic control index in advance, and the expected index value can be accurately given. The actual research and development experience of multiple space magnetic field measurement spacecrafts shows that the method according to the present invention can reach and be better than the task magnetic control index.
[0102] In summary, the embodiment of the present specification provides a spacecraft full-process magnetic control method and device, the method comprises: determining the demonstration single machine magnetic control index based on the single machine list, and determining the demonstration whole device magnetic control index based on the demonstration single machine magnetic control index; adjusting the single machine magnetic control index to determine the scheme single machine magnetic control index based on the scheme single machine magnetic control index and the scheme whole device magnetic control index; determining the scheme whole device magnetic control index based on the scheme single machine magnetic control index, and adjusting the scheme single machine magnetic control index to determine the preliminary sample single machine magnetic control index based on the scheme whole device magnetic control index and the scheme whole device magnetic control index; performing magnetic test based on the preliminary sample single machine magnetic control index, determining the test result, and adjusting the preliminary sample single machine magnetic control index to determine the positive sample single machine magnetic control index based on the test result and the preliminary sample whole device magnetic control index; determining the positive sample whole device magnetic control index based on the positive sample single machine magnetic control index, by executing different index decomposition algorithms, the spacecraft manufacturer can be guided to understand the magnetic control index in advance, and the expected index value can be accurately given.
