[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0042] The specific implementation of the concept of this application is described below.

[0043] Please refer to Figure 1 The embodiment of the present invention provides a method for obtaining high and low bandwidth data of a fiber optic gyroscope, the method comprising:

[0044] Step 100, obtaining low-frequency data and high-frequency data of the fiber optic gyroscope;

[0045] Step 102, packing the high-frequency data into a preset high-frequency data packet to obtain a gyro high-frequency data packet;

[0046] Step 104, according to the received control instruction, the gyro high frequency data packet is stored and sent to the space station data management subsystem.

[0047] In the embodiment of the present invention, the low-frequency data and high-frequency data of the fiber optic gyroscope are acquired in real time, and the high-frequency data is packaged into a preset high-frequency data packet to obtain a gyroscope high-frequency data packet, and then based on the received control instruction, the storage and transmission of the gyroscope high-frequency data packet are completed. In this way, by setting the preset high-frequency data packet and the control instruction, the high-frequency data of the fiber optic gyroscope can be stored and sent to the space station data management subsystem, which solves the problem that the massive high-frequency data of the existing fiber optic gyroscope cannot be stored in real time, and the high-frequency data of the fiber optic gyroscope can be further processed by the ground to complete the micro-vibration measurement of the whole satellite and realize the measurement and analysis of the load stability; at the same time, the low-frequency data can realize the high-precision attitude measurement of the satellite.

[0048] Described below Figure 1 How the various steps are performed.

[0049] First, in step 100, the sampling frequency of high-frequency data is higher than the sampling frequency of low-frequency data. Specifically, the control subsystem onboard computer obtains data from the fiber optic gyroscope through the 1553B bus, and simultaneously obtains the low-frequency data and high-frequency data of the fiber optic gyroscope, wherein the low-frequency data is used for real-time attitude measurement of the satellite. The fiber optic gyroscope products include fiber optic gyroscope line boxes and fiber optic gyroscope components. The fiber optic gyroscope products have high-bandwidth measurement functions and can meet the measurement requirements of satellite micro-vibrations. On the one hand, the fiber optic gyroscope line realizes the power supply of the fiber optic gyroscope and the gyroscope data acquisition function through the serial port in the downlink, and on the other hand, the uplink realizes the communication function with the control subsystem computer. Each set of products includes 3 mutually perpendicular fiber optic gyroscope heads, and the 3 channels of the gyroscope line correspond to the 3 fiber optic gyroscope heads respectively.

[0050] After step 100 and before step 102, the method further includes:

[0051] Determine the star time information when acquiring the high-frequency data and the fiber optic gyroscope channel information to which the high-frequency data belongs;

[0052] Obtaining the attitude determination mode of the system where the fiber optic gyroscope is located, the use mark of the star sensor, and the use mark of the fiber optic gyroscope under the star time information;

[0053] The star time information, the fiber optic gyroscope channel information, the attitude determination method, the star sensor use flag, and the fiber optic gyroscope use flag are added to the high-frequency data to obtain target high-frequency data, and the target high-frequency data is packaged into the preset high-frequency data packet.

[0054] Specifically, a preset high-frequency data packet is set in the onboard computer to store the high-frequency data of the fiber optic gyroscope, which is the target high-frequency data, including information such as star time information, fiber optic gyroscope channel information, attitude setting mode, star sensor use flag, fiber optic gyroscope use flag, etc. For example, the length of the preset high-frequency data packet is 960 bytes, and the data structure includes a packet leader-data type-frame count-attitude setting mode identification code-star time-channel information. Among them, the attitude setting mode identification code includes the attitude setting mode, the star sensor use flag, and the fiber optic gyroscope use flag.

[0055] In the present invention, high-frequency data is stored according to channel information, which is convenient for users to obtain corresponding high-frequency data according to the channel information when using it. At the same time, high-frequency data is packaged and stored with star time information, attitude determination method, star sensor use flag, fiber optic gyroscope use flag, etc., which further facilitates users to obtain the operating status of the star sensor and fiber optic gyroscope corresponding to the current high-frequency data, thereby facilitating the acquisition of detailed attitude information at the corresponding star time based on the gyro high-frequency data packet.

[0056] With respect to step 102, the high-frequency data is packaged into a preset high-frequency data packet to obtain a gyro high-frequency data packet, including: when the high-frequency data fills up the preset high-frequency data packet, the gyro high-frequency data packet is obtained.

[0057] In the present invention, each time the onboard computer fills up a preset high-frequency data packet, the packet is stored in the RAM area of ​​the onboard computer and simultaneously sent to the space station data management subsystem.

[0058] In step 104, the control instructions include a start storage instruction, a transmission permission instruction during imaging, a transmission prohibition instruction during imaging, and a stop storage instruction;

[0059] According to the received control instruction, the gyro high frequency data packet is stored and sent to the space station data management subsystem, including:

[0060] According to the received start storage instruction, start storing the gyro high-frequency data packet;

[0061] When receiving the instruction allowing sending during the imaging period during the storage process, acquiring the imaging start time and the imaging end time;

[0062] The gyro high-frequency data packet is stored in the time interval between the imaging start time and the imaging end time and sent to the space station data management subsystem.

[0063] It should be noted that the start storage instruction is used to instruct the storage of the gyro high-frequency data packet; the stop storage instruction is used to instruct the stop of the storage of the gyro high-frequency data packet; the allow sending instruction during imaging is used to instruct the storage of the gyro high-frequency data packet between the imaging start time and the imaging end time; the prohibit sending instruction during imaging is used to instruct the computer to store the gyro high-frequency data packet all the time and send it to the satellite data management subsystem at a fixed time. The user can design the sending time of each control instruction based on the actual application needs.

[0064] In the present invention, an imaging start and end time data packet is also designed, which includes the imaging start time and the imaging end time. The satellite data management subsystem sends the imaging start and end time data packet to the control subsystem onboard computer 120s±2s before the start of each imaging task, so as to obtain high-frequency data during the imaging process.

[0065] In the present invention, when receiving the instruction to start storing, the onboard computer stores the gyro high-frequency data packet. If an instruction to allow sending during imaging is received during the storage process, the imaging start time and imaging end time are obtained based on the imaging start and end time data packet, and the gyro high-frequency data packet is stored between these two times, and the data packet is sent to the space station data management subsystem, thereby realizing real-time storage and sending of the fiber optic gyroscope high-frequency data, instead of only receiving the whole-satellite microvibration measurement results returned by the fiber optic gyroscope.

[0066] In a preferred embodiment, step 104 includes:

[0067] According to the received start storage instruction, start storing the gyro high-frequency data packet;

[0068] When the instruction prohibiting transmission during imaging is received during the storage process, the gyro high-frequency data packet is stored and sent to the space station data management subsystem.

[0069] In the present invention, if a prohibition instruction to send during imaging is received after the storage of the gyro high-frequency data packet begins, it is not necessary to store and send the gyro high-frequency data packet only during the imaging process. Instead, the onboard computer will store the gyro high-frequency data all the time and send it to the digital control subsystem.

[0070] In some preferred embodiments, after step 104, the method further includes:

[0071] After storing and sending the gyro high-frequency data packet to the space station data management subsystem, the method further includes: receiving the stop storage instruction and stopping receiving the gyro high-frequency data packet.

[0072] In the present invention, the low-frequency data of the fiber optic gyroscope is stored and sent using the existing technology. In this way, the space station data management subsystem uses the low-frequency data of the fiber optic gyroscope to perform high-precision attitude measurement of the satellite, and can use the high-frequency data of the fiber optic gyroscope to complete the micro-vibration measurement of the entire satellite for payload stability measurement and analysis.
