Description

TECHNICAL FIELD

[0001] The application relates to the technical field of satellite attitude control, and particularly relates to a method for improving the precision of an integrated attitude measurement unit by using a Hongmeng operating system. BACKGROUND

[0002] Satellite attitude refers to the direction of a satellite when moving along an orbit. For most satellites moving around the earth, the direction is usually towards the earth, so as to help people realize resource investigation, climate monitoring, terrain exploration, signal relay and the like. However, since the space is in a weightless state, the attitude angle and the attitude angular velocity of the satellite often deviate from the design value when the satellite is moving. At this time, if the satellite is not limited, the satellite may rotate, so that the satellite cannot be normally used or even damaged. In order to avoid the occurrence of the situation, the spatial coordinate data of the satellite is measured and collected by the internal sensor of the satellite, and the data is transmitted to the on-board computer, so that the satellite is controlled at the target attitude by using various actuators.

[0003] However, since the calculation amount of the satellite is huge when the satellite is moving, the on-board computer is inevitably delayed and jammed during operation. At this time, the response speed of various sensors is directly affected, and the accuracy of the collection result may be reduced due to the reduction of the measured data, and the actual use effect of the satellite may be affected. Therefore, it is particularly important to improve the precision of the integrated attitude measurement unit. SUMMARY

DETAILED DESCRIPTION

[0058] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.

[0059] Embodiment:

[0060] The embodiment of the application provides a method for improving the accuracy of an integrated attitude measurement unit by using a Hongmeng operating system, which comprises the following steps:

[0061] Step one, determine the satellite attitude: clear the position of the satellite body relative to the space reference coordinate system, determine the space coordinates required by the satellite; the position includes the values of X, Y, Z three coordinate axis directions of the satellite body and the point on the track.

[0062] Step two, collect position data: through the integration of various data information by the Hongmeng operating system, the response speed of the measurement unit is improved, and the stability and reliability of the collection result are ensured; by collecting and measuring voltage, magnetic field intensity, angular velocity, pitch angle, etc., the corresponding index data can be obtained and arranged and collected, so that the related data can be called in time when determining the coordinate position in the follow-up, avoiding data confusion and increasing the calling time, and preventing data selection deviation.

[0063] Step three, create analysis task: through the Hongmeng operating system framework, the algorithm running speed is improved, so as to convert the satellite position data into corresponding driving signal in real time, and ensure the satellite attitude information control more accurate; according to the data type, the corresponding algorithm is selected by using the Hongmeng operating system, and at the same time, a variety of data are operated and processed, so that the space coordinates calculated by each data are more accurate under mutual corroboration, and then compared with the target coordinate, so as to determine the actual existing deviation distance.

[0064] Step four, control satellite attitude: through the driving signal to control the satellite surface execution component operation, to ensure that the satellite attitude is maintained on the target direction; through the execution component to push the satellite to reach the specified position in X, Y, Z three coordinate axis directions, to ensure that the satellite points to the target point on the earth.

[0065] Step five, running ability evaluation: the purpose is to track the operation under the control of the Hongmeng operating system, to evaluate the running performance, find out potential problems and improvement space; by recording the actual action effect to judge the problems existing in the attitude adjustment process, so as to find out the solution through the analysis and research of the corresponding data.

[0066] Step six, record and compare attitude data: used for storing the angle data and correction data of satellite attitude, the purpose is to compare the past data to assist the verification of the calculation results of the algorithm when the satellite moves along the orbit, to ensure the reliability of the results. For the target point that has been adjusted and corrected before, the corresponding driving adjustment parameters can be called to compare the current operation results, so that the data results are more reliable.

[0067] The specific way of determining the position of the satellite body in step one is:

[0068] Four-quadrant too sensitive multi-channel voltage: through the light irradiation, the metal plate surface electron escapes to the electrode, to absorb the charge in four electrodes and amplify the voltage signal after conversion, and through reading and processing to obtain the position and intensity of light for identifying satellite angle; use the phenomenon that the electron moves to different quadrant electrode after irradiation to make the voltage change accordingly to determine the direction and intensity of light, and then infer the space coordinates of satellite through the position of the sun.

[0069] Three-axis magnetic field: through the magnetic field, the magnetometer internal magnetic needle is affected, under the law of electromagnetic induction, the charge in a certain value resistance loop is measured to obtain the change of magnetic flux, and the satellite attitude data is determined through the space magnetic field; because the space near the earth is affected by the magnetic field, the satellite attitude data can be obtained simply and conveniently through the magnetometer, but the accuracy is relatively poor, so it can only play an auxiliary role.

[0070] Three-axis acceleration: through the acceleration of the satellite, the angular accelerometer measures the pitch angle and roll angle of the satellite; through the three-axis acceleration sensor, the acceleration of the satellite can be converted into other physical quantities such as resistance, voltage and capacitance, and then through the corresponding conversion and filtering, the physical quantity can be converted into a suitable output signal, at this time, the pitch angle and roll angle of the satellite can be obtained, so as to know the size of the force required to be applied to the satellite to change the corresponding angle.

[0071] Three-axis gyroscope: through the gyroscopic effect of the gyro, the state of the satellite is obtained. When the gyro rotates and is not hindered by external force, the direction of the gyro rotation axis remains unchanged under the action of fixed axis and precession, so the angular velocity along one or several axes can be measured, and then the accelerometer can be complemented to better track and capture the motion of the satellite in three-dimensional space.

[0072] The space coordinates required by the satellite in step one are input into the satellite by the ground timing through radio waves. The radio waves are S-band, X-band and KU-band. Through S-band, X-band and KU-band radio waves, the staff in the ground station can send the corresponding space coordinate point position to the computer inside the satellite in time, and the time consumption is short, the efficiency is high, and the influence of obstacles is small.

[0073] The specific steps of collecting position data in step two are as follows:

[0074] Determine the numerical type: based on the analysis and understanding of the data collected by each sensor based on the Hongmeng operating system, improve the data processing capability to improve the response speed of the sensor; through the Hongmeng operating system, the data information measured by each sensor is identified and classified, and then through unified planning, the data confusion is avoided to cause the difficulty of satellite computer processing, so as to prevent the normal collection of space data by each sensor.

[0075] Creating a collection set: receiving various types of data refreshed in real time through different sets to make data collection more intensive; creating a collection set so that different data information can be classified and saved, and can be refreshed in real time to continuously store a certain amount of collected information, thereby facilitating subsequent data calling, while reducing the processing difficulty of the on-board computer, so that the sensor can improve the response speed in the same time to provide more collected data.

[0076] Verify data uniformity: verify the data in the set according to the type of the set to ensure that the data in the set can show the measurement results of the sensor and avoid data receiving deviation; check the data in the set formed by the Hongmeng operating system to avoid data storage deviation in some cases, thereby avoiding reading errors when calling.

[0077] Determine data priority: distinguish between main and auxiliary sensor data through the Hongmeng operating system to improve the accuracy and reliability of the action result according to the main and auxiliary nature. According to the pre-set program, the data measured and collected by a certain sensor can be listed as the main reference, so as to be processed preferentially to improve the response speed, and the operation can be more accurate with the assistance of other collected data.

[0078] The specific steps of creating a parsing task in step three are:

[0079] Select algorithm program: based on the Hongmeng operating system, call the corresponding algorithm program according to the data type to convert spatial information into digital information, and sum and average the numerical values in real time as the final collection value; use the Hongmeng operating system to select the corresponding algorithm, so that voltage, magnetic field, acceleration, angular velocity, etc. can be verified through the corresponding algorithm to obtain the final collection value, and thus obtain more reliable satellite actual attitude data.

[0080] Verify algorithm result: repeat the algorithm calculation process to compare the results of two calculations to reduce the probability of algorithm operation error; repeat the calculation to prevent unexpected algorithm from affecting the actual calculation result, thereby improving the accuracy of the calculation result of the integrated attitude measurement unit.

[0081] Feedback abnormal data: compare the operation result according to the pre-set corresponding numerical value change range, and feedback the related collected data exceeding the normal range value to the ground workstation for verification and recalculation by the manual operation system. If the manual calculation result is still an abnormal value, it is discarded as a data set, and the next data set is selected for attitude adjustment. The corresponding collection process is checked, and the manual calculation is a normal value, which is transmitted back to the satellite through radio waves for adoption; by feeding back the abnormal value and the data in the corresponding set, the staff can timely discover potential vulnerabilities and avoid abnormal values affecting the correct judgment of the attitude.

[0082] Analyzing data results: through the analysis of digital signals by the Hongmeng operating system, corresponding instructions are issued to drive the satellite to execute components; through the Hongmeng operating system, the operation results can be actually applied to the execution components through instructions.

[0083] Recording numerical results and system information files: the algorithm calculation results and system operation information files are recorded and stored for subsequent query and retrieval:

[0084] Updating algorithm program: according to the actual use demand and the vulnerability, the algorithm is optimized and adjusted to save the operation time and improve the working efficiency of the Hongmeng operating system. Through the optimization and update of the algorithm, the algorithm can be continuously improved to meet the gradually increasing use requirements.

[0085] The specific steps of controlling the satellite attitude in step four are:

[0086] Receiving action instructions: the Hongmeng operating system sends instructions to each execution component to control the execution component to output corresponding action force; through the Hongmeng operating system, the execution component moves according to the operation results to change the satellite attitude.

[0087] Judging the action sequence: according to the instructions, each execution component acts in turn to adjust the satellite attitude and ensure that the satellite is directly opposite the target area; through the sequential action of the execution component, the satellite attitude can be adjusted to the required state to accurately photograph the target object.

[0088] Compensating action torque: through the action of the reverse execution component, the interference torque after the change of the satellite trajectory is compensated to avoid large changes in the satellite attitude during control; due to the lack of gravity in space, to avoid the satellite action exceeding the expected range, a compensation torque needs to be applied to the execution component to offset the movement trend.

[0089] Verifying feedback driving torque: through the verification of the torque output by each driving component after action, the adjustment of the satellite attitude is ensured to conform to the control results of the Hongmeng operating system, and the verification results are transmitted for collection and statistics by the workstation staff. Through the verification of the output torque, the accuracy of the action of each execution component under the control of the Hongmeng operating system is verified.

[0090] In step four, the attitude is adjusted through three-axis attitude stabilization, so that the corresponding solar panels and lenses can normally play a role, and three-axis attitude stabilization is used to actively adjust the attitude.

[0091] The specific steps of running the capability evaluation in step five are:

[0092] Analysis of defects: through the satellite feedback data analysis to find abnormal factors, determine the scope of the problem: through the self-check feedback data to reduce the probability of potential problems.

[0093] Data retrieval: retrieve abnormal value data collection set and the connected time period data collection set, analyze the causes and determine the root cause of the problem; use radio waves to actively retrieve the measured data and calculated values collected during the attitude adjustment of some satellites to find the cause of the problem.

[0094] Improved test: improve the algorithm, build a simulation environment through the Hongmeng operating system to verify the running effect of the improved algorithm; test the improved algorithm through the Hongmeng operating system to verify the improvement effect, and shorten the response time of the algorithm and sensor, so that the communication rate of the integrated attitude measurement unit and the on-board computer can be improved with the increase of the task response speed.

[0095] Monitoring operation effect: continuously track the algorithm running situation and make corresponding optimization according to the actual situation. Through a certain length of tracking verification, the purpose of completely eliminating potential problems is verified.

[0096] The specific steps of recording and comparing attitude data in step six are as follows:

[0097] Confirm target information: used to confirm the recorded archives of the target to be shot when the satellite moves in the past; query the current target information in the recorded numerical results and system information files to determine whether the past verification can be performed.

[0098] Past position retrieval: retrieve the recorded calculation results and action angle values in the past;

[0099] Numerical comparison: compare the attitude adjustment information of the same target point in the past and now to verify the calculation results of the algorithm; compare various data to further confirm the reliability of the calculation results, so that the satellite attitude information control is more accurate.

[0100] Record storage: record the comparison results and this time attitude adjustment information for subsequent retrieval and correction. Record and store various data to make it easier to know the accurate cause when problems occur later.
