Description
Technical Field
The application relates to the technical field of satellite task simulation, in particular to an energy constraint system and method for a satellite planning task, which are applied to earth observation satellites needing task planning and used for carrying out energy constraint check on the planning task in the whole satellite operation period.
Background
The earth observation satellite carries a satellite-borne sensor such as visible light, electronic reconnaissance and synthetic aperture radar, acquires information such as images and signals of ground targets, and transmits the information back to the ground station for analysis and use. Because the cost of the satellite is high, the satellite resources are precious, and in order to fully utilize the satellite-ground resources and exert the satellite efficiency to the maximum extent, the task planning of the satellite is necessary to maximize the utilization of the satellite resources. In the mission planning process, due to the limited satellite-ground resources, many constraints, such as satellite attitude constraint, load working capacity constraint, satellite energy constraint and the like, need to be considered in the mission planning. In the past, the attitude maneuvering capability and the satellite load working capability of the satellite limit the task execution quantity of a single track, the constraint of the energy source of the satellite on the task does not become the main limitation of the task realization capability of the satellite, and the energy source constraint is not considered when the task planning of the satellite is carried out or the energy source consumption during the load working period is simply considered. With the improvement of the satellite attitude mobility and the load performance, the working level of the satellite is greatly improved, but the energy consumption of the satellite is increased, and the expected use condition of the satellite energy is necessarily estimated, so that the condition that the satellite is insufficient in energy when executing a task is prevented, the satellite fault and the task cannot be completed smoothly.
At present, the research of Energy constraint aiming at satellites is less, and Trevor Bihl et al propose a Modeling method and an analysis Tool of a satellite Energy System (Bihl T, Heidenreich J, Allen D, et al SPECTRA: A Space Power System Modeling and Simulation Tool [ C ]// International Energy Conversion Engineering conference.2013). The inventor proposes a simulation analysis method of the energy of a near-earth satellite power supply system (the inventor, the Lin Baojun, the Lu Congren. the simulation analysis of the energy of the near-earth satellite power supply system [ J ]. computer simulation, 2005,22(8): 35-36). The method can realize energy consumption calculation of the satellite and is used for guiding the design of a satellite power supply system, but energy constraint inspection is not performed on a satellite planning task. The invention discloses a remote sensing satellite energy balance constraint analysis system and method (application number: 201610609295.1) which can carry out planning task energy constraint check aiming at attitude maneuver and is disclosed by Qiao Jie Shi et al in the Chinese invention patent application. Zhang Yong et al in the Chinese patent application "a short-term payload work planning method for improving the energy utilization efficiency of satellites" (application number: 2016108333288.X) discloses that energy constraints can be applied to the short-term payload in each orbital circle in which a satellite is operating.
However, the existing energy balance calculation method and energy constraint system can perform energy constraint calculation on a single planning task or a single-orbit planning task, but cannot perform accurate energy constraint check on multiple satellite planning tasks in the whole operation period of the satellite. Three problems are faced when the task energy constraint inspection is planned in the practical application of the systems: firstly, the initial energy value needs to be given manually when energy constraint calculation is carried out each time, the energy condition at the beginning of a task is often unknown when the task is planned, and particularly the initial energy value at the future time cannot be known when the future task is planned; secondly, due to the simplification of modeling and the change of satellite power consumption, the deviation of a calculation result and an actual result occurs, and error accumulation can be caused when correction is not carried out, so that the final calculation result is influenced; and thirdly, if the planned task cannot meet the energy constraint condition, only a result of failure is given, and a planning task adjustment suggestion is not provided, so that the task is not rapidly adjusted in the later period, and the whole task planning period is too long.
Therefore, there is a strong need in the art to develop an energy constraint system and method for satellite planning task, which performs energy constraint check on the planning task during the whole satellite operation period.
Disclosure of Invention

Detailed Description
The technical solution of the present application will be clearly and completely described below with reference to the accompanying drawings and the embodiments of the present application.
In a first aspect, the present application provides an energy constraint system for a satellite planning task, which is centered on an energy source database and comprises five modules, namely, task period energy constraint calculation, task adjustment, non-task period energy calculation, telemetry correction and database maintenance. The task period energy constraint calculation module is an existing energy constraint system, and the other four modules are the method provided by the application. The energy source database can calculate and accurately record the energy consumption condition of the whole operation period of the satellite through the five modules, and finally the purpose of performing energy constraint on the planning task is achieved.
The task period energy constraint calculation is similar to the existing energy constraint analysis method, the system firstly obtains a planned task time table and an orbit information table of satellite in-out ground shadow time, judges the working mode and the charging and discharging state of the satellite by combining the attitude adjustment strategy of the satellite, and can calculate the energy consumption condition of the satellite in a period of time by combining the energy consumption of the satellite in different working modes to judge whether the planned task meets the energy constraint of the satellite.
The task adjusting module is the method provided by the application. When the task energy constraint can not pass, the system utilizes the task adjusting module to adjust the planning task. The specific implementation method comprises the steps of inquiring the tasks before the energy constraint does not pass through the time point, deleting or shortening the task time from low to high according to the task priority until the adjusted tasks can meet the energy constraint. And after the task adjustment and the energy constraint calculation are finished, outputting an energy constraint result and a task adjustment suggestion.
The calculation of the energy in the non-mission period is the method provided by the application. The module realizes energy calculation in the non-task period, ensures the time continuity of energy data in the energy source database, and can accurately acquire the initial energy value from the energy source database when energy constraint is carried out in the task period. The calculation mode is similar to the task period energy calculation, but only the satellite orbit information and the attitude adjustment strategy are considered.
The telemetry correction module is the method proposed by the application. The system monitors the energy telemetering data of the satellite, calculates the energy value of the satellite at a certain time point from the energy telemetering data, compares the energy value with the energy data of the time point in the energy constraint system, corrects the energy data in the system into telemetering calculation data when the energy value and the energy data are inconsistent, and corrects the data after correction points in the system.
The database maintenance module is the method provided by the application. The module realizes maintenance of data generated by the four modules, including operations of merging of coincident data, deleting of redundant data, updating of energy data and the like.
Referring to fig. 1, fig. 1 is a system schematic of the present application. The system takes an energy source database as a center, and the task period energy constraint calculation, task adjustment, telemetering correction and non-task period energy calculation modules generate data interaction with the energy source database, and the data are managed by the energy source database maintenance module, and operations such as data retention, deletion, update, discarding and the like are implemented.
In the system, a mission period energy constraint calculation module is started and called by a mission planning system in a mission period. And when the call of the task planning system is received, the energy constraint system reads the start time and the end time of the task from the planning task table, and acquires the energy value of the initial time from the energy source database as the initial value for calculation. And then according to the input planning task table and the orbit information table, combining with a satellite attitude adjustment strategy, comprehensively obtaining the working mode of the satellite, judging the charging and discharging conditions of the satellite, and finally combining with the power consumption table under each working mode, calculating the energy change of the satellite until the calculation is finished.
Referring next to fig. 2, fig. 2 shows a task adjustment diagram in the present application, where the task adjustment module is invoked by the task period energy constraint calculation module when the task does not satisfy the energy constraint. At T5At that moment, the calculated energy value is lower than the energy threshold, and the model will calculate T6Time of day and obtaining energy value V of model at the time of day1With which it can be calculated to satisfy T6The energy value at the moment is greater than the energy threshold, requiring a shortened mission time. Due to T1When the energy value is full, the previous task is not adjusted any more, and the moduleType is only to T1-T6The task in between. As used herein, the term "full energy value" means that the satellite battery power source is fully charged. The model searches the task with the lowest priority one by one, if the task meets the energy constraint, the adjustment function is quitted, otherwise, the task with the priority or the task with the next lower priority is continuously adjusted. The adjustment includes shortening a task time or deleting a task. And after the task is adjusted, updating the originally changed energy data in the energy source database. And after the calculation is finished, outputting the code number of the adjustment task, and performing task adjustment by the task planning system. FIG. 2 shows adjusting T4-T6The post-mission energy value changes.
Fig. 3 shows a flow chart of the non-duty period energy calculation in the present application. And automatically calculating the timing of the model during the non-task period, and only considering the satellite orbit information and the attitude adjustment strategy. The model firstly obtains the latest time point from the energy source database as the calculation starting time, obtains the energy value of the time from the energy source database as the calculation initial value, reads the orbit information of the satellite after the time point from the orbit information table, calculates the energy by referring to the satellite attitude adjustment strategy, and injects the result into the energy source database.
FIG. 4 shows a telemetry calibration schematic of the present application. The system introduces satellite telemetry to correct energy values in the energy database. The satellite residual capacity is related to current, internal resistance and temperature, and the complicated electrochemical reaction in the battery causes the estimation method of the battery residual capacity to be complicated and the estimation result to be inaccurate, so that the energy residual capacity is difficult to estimate by using the satellite remote measurement.
However, the satellite square matrix current, the load current, and the charge/discharge current can be used to determine whether the satellite power source is fully charged. And in the model, acquiring the energy remote measurement of the satellite, and correcting the energy value of the corresponding time point in the energy source database to be full when the power supply is judged to be full. During correction, energy calculation does not need to be carried out on the energy after the time point of correction, and only corresponding linear translation is carried out according to the change of the energy value at the time point of correction until the next time point when the energy value is full. Model detection of T1If the energy source is full at the moment, the energy source database can be filled with energyT of1And correcting the energy value after the moment. T is1-T2During the charging state of the energy source, the energy source is full all the time, T2At any moment, the satellite energy increases H1Increasing H to the subsequent energy value1Until the energy source is full. At T4Energy value increase H at time2Due to the increase of H2<H1Then the subsequent energy value is increased by H2Until the energy source is full. T is6The energy before the correction is full at all times, and the subsequent energy does not need to be corrected.
The system establishes three data tables in the energy source database to maintain the energy source database: task period data tables, non-task period data tables, and energy data tables. And after the calculation is finished, if the task table indicates that the task is finally annotated, copying the calculated data to the energy data table, covering the data in the energy data table within the same time, correcting the subsequent data of the task, and otherwise, not copying the data. And during the non-task period calculation, the model inquires the energy data table and the non-task period data table, acquires the latest time as the calculation starting time to read the corresponding track information table for calculation, inquires the latest time of the energy data table and the corresponding energy value thereof after the calculation is finished, and copies the data later than the time point in the non-task period data table to the energy data table after correcting. The energy data table stores the on-satellite energy value and records the on-satellite energy consumption condition. And providing an initial value for calculating the energy constraint in the mission period, and receiving telemetry data correction.
In a second aspect, the present application provides a method for energy constraining a satellite using an energy constraining system for a satellite planning task as described in the first aspect, the method comprising the steps of:
(1) in a task period, the energy constraint system aiming at the satellite planning task calls the energy constraint calculation module in the task period to judge that the satellite planning task meets energy constraint or the satellite planning task does not meet the energy constraint, if the planning task meets the energy constraint, the step (2) is implemented, and if the planning task does not meet the energy constraint, the step (3) is implemented;
