Description

Technical Field

[0001] The embodiments of this specification relate to the field of aerospace technology, and in particular to an on-orbit micro-vibration data processing method. Background Art

[0002] The on-orbit micro-vibration environment of spacecraft is the main source of interference during on-orbit camera imaging, intersatellite laser payload link building and laser tracking. Based on a large amount of ground micro-vibration tests and on-orbit micro-vibration measurement data, the identified micro-vibration disturbance sources include antenna rotation, solar wing rotation, flywheel rotation, CMG operation, etc. The disturbance forces generated by these disturbance sources are transmitted to the camera lens and laser payload transmitting end through the spacecraft structure, affecting the camera imaging accuracy and laser payload stable tracking.

[0003] The impact of micro-vibration on the imaging quality of aerospace optical cameras is mainly reflected in two aspects: first, the visual axis jitter caused by the relative movement of the image plane and the detector; second, the surface shape changes of each optical element and the rigid body displacement generated between them cause the optical system transmission function to decrease; the impact of micro-vibration on the quality of aerospace laser communication is mainly through the superposition of the inherent error of the PAT system, which will cause the optical antennas of both communicating parties to jitter, thereby increasing the communication bit error rate. When the control error caused by the vibration of the satellite platform is relatively light, the signal-to-noise ratio and communication quality of the system will decrease;

[0004] In the project, various disturbance sources on the spacecraft are mainly identified through ground micro-vibration tests, and their response characteristics are collected on the ground to correct the working information of key payloads. Considering the boundary difference between the micro-vibration environment of the spacecraft on orbit and the ground, the ground micro-vibration simulation cannot completely reproduce the on-orbit state, so it is necessary to conduct micro-vibration tests on orbit, use the on-orbit measurement data to truly reflect the disturbance information on orbit, and use this as a basis to carry out micro-vibration suppression and image correction. Therefore, it is necessary to set up micro-vibration sensors and signal collectors on the spacecraft to collect micro-vibration data.

[0005] Since the in-orbit data transmission needs to be packaged and transmitted through special protocols such as RS422, 1553B, CAN, Ethernet, etc., a large number of data packets will be formed after the micro-vibration data is transmitted to the ground, and packet loss and error will occur during the transmission process. Therefore, a better solution is urgently needed. Summary of the invention

[0044] Many specific details are described in the following description to facilitate a full understanding of this specification. However, this specification can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of this specification, so this specification is not limited to the specific implementation disclosed below.

[0046] It should be understood that although the terms first, second, etc. may be used to describe various information in one or more embodiments of this specification, this information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of one or more embodiments of this specification, the first may also be referred to as the second, and similarly, the second may also be referred to as the first. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0047] In this specification, an on-orbit micro-vibration data processing method is provided. This specification also relates to an on-orbit micro-vibration data processing device, a computing device, and a computer-readable storage medium, which are described in detail one by one in the following embodiments.

[0048] See also Figure 1 , Figure 1 A flow chart of an on-orbit micro-vibration data processing method provided according to an embodiment of the present specification is shown, which specifically includes the following steps.

[0049] Step 101: The micro-vibration on-orbit measurement device packages, stores and groups the micro-vibration measurement data, determines a micro-vibration measurement data packet, and sends the micro-vibration measurement data packet to a ground receiving end.

[0050] In practical applications, all on-orbit micro-vibration data packets can be directly downloaded to ground analysis equipment. The equipment has sufficient storage space to accommodate the space where the on-orbit data packets are located and the space occupied by the parsed data. The data packets are then classified and sorted according to the packet classification code and timing code.

[0051] For example, data packets are transmitted on-orbit via Ethernet, with a single data packet size of 64MB and a built-in checksum.

[0052] It should be noted that the data packet may also be an RS422 data packet or a 1553B data packet, which is not limited in the embodiments of this specification.

[0053] Step 102: The ground receiving end unpacks the micro-vibration measurement data packet through packet segmentation, verification and analysis methods, and restores it to time domain data.

[0054] In one possible implementation, the ground receiving end unpacks the micro-vibration measurement data packet through a packetization, verification and analysis method to restore it to time domain data, including: parsing the micro-vibration measurement data packet through a packetizer to determine the grouped data packet; verifying the grouped data packet through a verifier to determine the verification data packet; and unpacking the verification data packet based on a decoder to restore it to time domain data.

[0055] In practical applications, see Figure 2 , the scheme includes a packetizer, a checker, a decoder, a time domain interceptor, a frequency domain converter and a data corrector. The packetizer can classify and sort the data packets according to the data packet classification code, the checker can check the packet loss and overlap according to the data packet check code, the decoder can decode the on-orbit data packet and convert it into micro-vibration time domain data, the time domain interceptor can intercept the time domain data near the time point of interest, the frequency domain converter can perform frequency domain conversion on the intercepted time domain data, and the data corrector can correct the micro-vibration data according to the on-orbit environmental parameters based on the ground environmental parameter calibration results of each sensor.

[0056] Specifically, the micro-vibration measurement data packet is parsed by a packetizer to determine the grouped data packet, including: parsing the micro-vibration measurement data packet by a packetizer to determine the packet classification code; storing the micro-vibration measurement data packet into a target folder based on the packet classification code; and sorting the data packets in the target folder according to the time code to determine the grouped data packet.

[0057] In practical applications, see Figure 3 ,The packet depacketizer is used to parse the on-orbit data packets, distinguish multiple data packets according to the packet classification codes and place them in different folders, and arrange the data packets in the same folder according to the time code.

[0058] Among them, the packetizer packets the data according to the on-orbit encoding method.

[0059] In a possible implementation, verifying the packet data packet by a verifier to determine the verified packet includes: verifying the packet data packet by a verifier to determine an abnormality; and processing the packet data packet based on a preset exception processing rule to determine the verified packet.

[0060] In practical applications, the verifier is used to check the check codes in the data packets in the same folder to check whether there is packet loss or packet duplication, record the packet loss, and remove the duplicated packets.

[0061] Specifically, the verifier can verify data packet loss and packet duplication based on the verification code in the on-orbit data packet.

[0062] In a possible implementation, unpacking the verification data packet based on a decoder and restoring it to time domain data includes: unpacking the verification data packet based on a decoder in sequence and restoring it to continuous time domain data.

[0063] In practical applications, the decoder unpacks the verified data packets in the same folder in sequence and converts them into continuous time domain data.

[0064] Furthermore, the decoder parses the data according to the packetization and verification results and the on-orbit data encoding method, and the parsed data types include acceleration data, temperature data, angular displacement data and force data.

[0065] Step 103: Use data interception and frequency domain conversion methods to process the time domain data, and make corrections based on on-orbit environmental parameters to obtain frequency response information of each measuring point.

[0066] In a possible implementation, the time domain data is processed using a data capture and frequency domain conversion method, including: determining a target time period, capturing the time domain data using a time domain capturer based on the target time period, and determining the captured data; wherein the capture length is determined based on a target frequency band range; and performing frequency domain conversion on the captured data using a frequency domain converter to obtain initial frequency response data of each measuring point.

[0067] In practical applications, the time domain interceptor is used to intercept the time domain data of the time period of interest, and the interception length depends on the frequency band range of interest. The frequency domain converter converts the intercepted time domain data into the frequency domain to obtain the PSD spectrum data of each measuring point in the time period, and the micro-vibration frequency response of the frequency of interest can be viewed.

[0068] Specifically, the time domain interceptor verifies all types of data, and the intercepted data length is based on the frequency band range of interest. In this embodiment, the frequency band range of interest is 1 Hz to 500 Hz, and the interception time is not less than 10 / 1 Hz = 10 s, where 1 Hz is the minimum frequency of interest.

[0069] Furthermore, the frequency domain converter can convert the micro-vibration time domain signal into a PSD spectrum for all micro-vibration response data, including acceleration data, disturbance force data and angular displacement data.

[0070] It should be noted that the frequency domain data type may also include AUTOPOWER and FFT spectrum, which is not limited in the embodiments of this specification.

[0071] In a possible implementation, correction is performed according to on-orbit environmental parameters to obtain frequency response information of each measuring point, including: determining temperature data according to the on-orbit environmental parameters, correcting initial frequency response data of each measuring point based on the temperature data, and determining frequency response information of each measuring point.

[0072] In practical applications, the data corrector can correct the time domain and frequency domain data according to the temperature measurement result at that moment and the sensitivity of the sensor installed at each measuring point at that temperature.

[0073] Specifically, the data corrector can correct the measurement results according to the on-orbit temperature based on the sensitivity test data of the ground sensor at different temperatures. The initial sensitivity of the micro-vibration sensor is S0, and the function of the micro-vibration sensor sensitivity S changing with temperature T is S(T). This function curve is obtained by fitting the test data of the ground temperature-sensitivity calibration test. According to the on-orbit temperature measurement data T(t), the sensitivity of the micro-vibration sensor at time t is S(T(t)). The on-orbit micro-vibration response is corrected according to the sensitivity, and the original response curve over time is A 修正前 =A(t), the modified micro-vibration response time function is:

[0074] A 修正后 =A(t)×S(T(t)) / S0;

[0075] After data processing, it was found that the frequency domain data of each measuring point had an obvious response at the operating frequency and multiple frequency of the interference source. Based on this response, the working data of the on-orbit sensitive payload (camera or laser communicator) was interpreted or corrected.

[0076] The embodiments of this specification provide an on-orbit micro-vibration data processing method and device, wherein the on-orbit micro-vibration data processing method includes: the micro-vibration on-orbit measurement device packages and stores the micro-vibration measurement data, determines the micro-vibration measurement data packet, and sends the micro-vibration measurement data packet to the ground receiving end; the ground receiving end unpacks the micro-vibration measurement data packet through packetization, verification and analysis methods, and restores it to time domain data; the time domain data is processed using data interception and frequency domain conversion methods, and corrected according to the on-orbit environmental parameters to obtain the frequency response information of each measuring point. The on-orbit data packet is converted into continuous time domain data through classification, verification and analysis methods, and then the continuous time domain data is processed using data interception, frequency domain conversion and data correction to obtain the frequency response information of the on-orbit micro-vibration, thereby improving the accuracy of the data.
