Detailed Description
The present invention will be described in further detail with reference to specific examples, but embodiments of the present invention are not limited thereto.
The mapping table-based autonomous generation method of the imaging instruction sequence of the agile satellite can be applied to satellites such as communication satellites and remote sensing satellites, and the specific type of the satellites is not limited in the embodiment of the invention.
Fig. 1 is a schematic flow chart of an autonomous generation method of an agile satellite imaging instruction sequence based on a mapping table according to an embodiment of the present invention. By way of example and not limitation, the method 100 may include steps S101-S105. The steps are described below.
S101, matching a task system mapping table according to task basic information of a current task to obtain a system for executing the current task.
For example, the task information of the current task may include task basic information, service information, and time information.
By way of example, the task basic information may include a task ID (task ID), a task type (IMType), a camera for imaging (fu_cam), and a camera number (cam_id).
By way of example, a system for performing a respective task may include one or more of the following: control system, data transmission antenna system, program control system, camera system.
Alternatively, the camera system may include a visible camera, an infrared camera, and a wide-format camera.
In some embodiments, the system performing the current task may be determined based on task base information in the task information (e.g., task type or camera used for imaging), matching a task system mapping table.
For example, if the current task includes multiple systems, each system may be used to perform one of the subtasks in the current task. Each subtask has own execution time length and execution time.
In one possible implementation, the task system mapping table may store mapping relationships between different task basic information (e.g., task types or cameras used for imaging) and the system.
For example, referring to fig. 2, when imtype=0x4000 in the task information, the system performing the current task includes a program control system, a data transmission antenna system, and a control system. When fu_cam in the task information is d1= 1>0, the systems performing the current task are the visible camera and the infrared camera in the camera system.
For example, referring to FIG. 3, the mission system mapping table may be stored in the satellite in the form shown by the following formula.
Where, the assignment indicates that it is a task system mapping table, the param is a value for determining a condition of the system, for example, "IMType and fu_cam", and the Terminal is a system corresponding to the condition. Different values of IMType and fu_cam correspond to different characteristic value sequences, respectively, e.g. imtype=0x4000 corresponds to param 1 Post-eigenvalue sequence value 1 ,value 2 ,...,value j . Different systems also correspond to different characteristic values, and the characteristic values of the system for executing the current task can be matched according to the param characteristic sequence, so that the system for executing the current task is obtained.
In one example, if the program control system is matched according to the task system mapping table, step S104 and step S102 may be performed simultaneously.
In another example, if the program control instruction mapping table is not matched according to the task system mapping table, only the steps S102, S103 and S105 are needed.
In other embodiments, before executing step S101, the task setting information may be acquired first, and the task system mapping table, the service instruction mapping table, the time constraint mapping table, and the program control instruction mapping table may be determined according to the task setting information.
In one possible approach, the task system map, business instruction map, time constraint map, and program instruction map may be stored in the satellite in a form similar to equation (1) above.
In another possible implementation manner, the method can be further described through second-order predicate logic, and files described through the second-order predicate logic are stored in the satellite, so that a user can conveniently analyze the feasibility of the method.
In one example, referring to the task system mapping table in equation (1), performing a second order predicate logic description on it may result in a file as shown in the following equation:
where x represents a task. The assignment (x) indicates that the task x belongs to the "assignment" set, i.e. it is a task that needs to fulfill a specific condition. UsingThe symbols "present", "→" denote a logical "implication", i.e. if the preceding condition is met, the following condition must also be met. That is, the predicates P, Q and R exist to satisfy the conditions of parameter (x, P), value (P, Q), valid_value (Q), and terminal_value (x, R). This condition means that if a task x belongs to the "transmission" set, then there is a parameter name P and a parameter value name Q, and Q is a valid parameter value, then the Terminal (system) value of task x is R.
In another example, referring to the business instruction mapping table in the following formula (10), a second order predicate logic description is performed on the business instruction mapping table, and a file shown in the following formula can be obtained:
where x represents an instruction. Terminal (x) means that instruction x belongs to the "Terminal" set, i.e. the current Terminal instruction. UsingThe symbols "present", "→" denote a logical "implication", i.e. if the preceding condition is met, the following condition must also be met. That is, the predicates C, Q and R exist to satisfy the conditions of condition_name (x, C), value (C, Q), valid_value (Q), and encoding_value (x, R). This condition is expressed as If an instruction x belongs to the "Terminal" set, then there are C, Q, R elements that satisfy the condition of instruction x as C, C has a value of Q, and Q is a valid value. And instruction x is present with number R.
In yet another example, a second order predicate logic description of the program controlled instruction mapping table in equation (12) below may be referred to as a file as shown in the following equation:
where x represents an instruction. The transmission (x) indicates that task x belongs to the "transmission" set, i.e. it is a task that needs to meet a specific condition. UsingThe symbols "present", "→" denote a logical "implication", i.e. if the preceding condition is met, the following condition must also be met. I.e. the presence predicates P, Q and R satisfy property condition Conditions of (x, P), value (P, Q), valid_value (Q), and encoding (x, R). This condition means that if a task x belongs to the "transmission" set, then there is a parameter name P and a parameter value name Q, and Q is a valid parameter value, then the encoding value of instruction x is R.
In yet another example, a second order predicate logic description of the time constraint map in equation (11) below may be found with reference to the time constraint map, which may be a file as shown in the following equation:
Where x represents an instruction constraint. Restaint (x) means that constraint x belongs to the "restaint" set. UsingThe symbol "present", "→" means logic "inclusive", e.g.)If the former condition is satisfied, the latter condition must also be satisfied. That is, there are predicates C, Q, S and R that satisfy the conditions of condition_name (x, C), value (C, Q), valid_value (Q), parameter (x, S), and property (x, R). This condition means that if an instruction constraint x belongs to the "reset" set, there are C, Q, S, R four elements that satisfy the condition of instruction x as C, the value of C as Q, and Q as a valid value. And the value of parameter for which constraint x exists is S, property is R.
In another possible implementation manner, the mapping table can be described in a functional manner, and the file described by the function is stored in the satellite, so that the user can conveniently understand the mapping relation in each mapping table.
In one example, referring to the task system mapping table in the above formula (1), describing a function thereof, a file shown in the following formula may be obtained:
terminal=Mission(param i (value j )),i=1,2,3,...,n,j=1,2,3...m (6)
this function represents that the selected system depends on the attribute information param in the task information mix i Value of (2) j . When i, j take different values, they correspond to different terminal.
In another example, referring to the service instruction mapping table in the following formula (10), describing a function thereof, a file shown in the following formula may be obtained:
instruction=Terminal(condition i (value j )),i=1,2,3,...,n,j=1,2,3...m (7)
this function indicates that the execution content (instrumentation) of the current task depends on the value valuej of the attribute information conditionni in the task information corresponding to the system. When i, j take different values, they correspond to different instractions.
In yet another example, a function description of the program-controlled instruction mapping table in the following formula (12) may be referred to as a file shown in the following formula:
this function shows that the program-controlled satellite instructions depend on the critical condition property in the Instruction condition And encoding. When i, j take different values, they correspond to different instractions.
In yet another example, a function description of the time constraint map in equation (11) below may be referred to as a file as shown in the following equation:
this function represents that the constraint depends on the key element property in restaint conditioni Value of (2) j . When i, j take different values, they correspond to different restpoints.
S102, matching the service instruction mapping table according to the service information of the current task to obtain the execution content of the current task.
For example, the current task may be split into at least one subtask.
By way of example, the execution of the current task may include one or more of the following: the execution time of each subtask, the imaging class of the camera, the working mode of the system.
For example, the service instruction mapping table may store mapping relations between different service information and different execution contents, and may be matched according to attribute information in the task information, so as to obtain the execution content of the current task.
By way of example, the service information may include: information such as a camera (fu_cam) used for imaging, an imaging type (f_calt) of the camera, an antenna type (DTAType), and the like.
For example, when the system is a camera system and the imaging category f_calt=1, the imaging category of the corresponding camera may include calibration imaging, and the execution duration of the subtask performed by the camera system may be 2 minutes. If the current task is executed at a time of 10:00 and the execution time is 3 minutes, the execution time of the subtasks executed by the camera (i.e., the time to start imaging) may be 10:00. When the system is a camera, the imaging category f_calt=4, the imaging category of the corresponding resulting camera may include direct imaging, and the execution duration of the subtasks performed by the camera may be 40 seconds. When the system is a data transmission antenna system, the working mode of the data transmission antenna system can be a recording mode, and the execution time (i.e. the time for starting recording) of the data transmission antenna can be 10:00.
In one example, a similar service instruction mapping table may also be stored in the satellite in the form of equation (10), see equation (10) below.
Wherein terminal_id represents an identification of a system executing a current task, id is an instruction block code of the system, condition is a characteristic value sequence corresponding to a judgment condition for determining execution content of the current task, and the judgment condition is stored in a satellite in different characteristic values. The encoding_value is a feature value sequence corresponding to the execution content under the condition. When the specific value of the encoding_value is obtained according to different conditions, the execution content of the current task can be determined.
For example, referring to fig. 4, the execution systems obtained from the task system mapping table are visible cameras and infrared cameras. The feature values of the corresponding encoding_value are 0x11 and 120 when the value of the camera (fu_cam) used for imaging and the imaging class (f_calt) of the camera are all 2, which means that single scale imaging is 120 seconds.
And S103, matching the time constraint mapping table according to the time information of the current task to obtain the constraint condition for executing the current task.
By way of example, the time information may include: push broom flag (f_scantype), execution time of current task (t 0), execution duration of current task (dt), maneuver time of current task (texe).
By way of example, the constraints may include one or more of the following: motorized lead time of each subtask, task maximum execution duration of each subtask.
In some embodiments, the time constraint mapping table may be matched according to the time information of the current task or the time information of the current task and the time information of the last task, so as to obtain the constraint condition for executing the current task.
In one possible implementation manner, if the system for executing the current task includes a control system, the time constraint mapping table may be matched according to the time information of the current task and the time information of the previous task, so as to obtain the constraint condition for executing the current task.
For example, if f_scantype=0 for the current task, the push-broom mode of the control system is active push-broom; f_scantype=0 of the last task, the push-broom mode of the control system is also active push-broom, the maneuver time of the current task is texe, the task lead time of the subtask executed by the control system is 2 seconds, and the maneuver time of the subtask is texe-2.0.
In another possible implementation manner, the time constraint mapping table may be matched according to the time information of the current task, so as to obtain the constraint condition for executing the current task.
For example, when the execution system of the subtask is a camera, the values of the camera (fu_cam) used for imaging and the imaging class (f_calt) of the camera are all 2, the execution time of the current task is t0, the execution time period is dt, the post-task time is 30 seconds, the imaging end time of the camera is t0+dt+30, and the maximum execution time period of the task (i.e., the maximum imaging time period of the camera) is 10 minutes.
In one example, the time constraint map may also be stored in the satellite in the form of equation (11), see equation (11) below.
Wherein, restrant represents a time constraint mapping table, time constraintThe mapping table can reflect the Terminal type (terminal_id), the judgment condition (condition) for determining the constraint condition, and the constraint condition (property) obtained finally target ) Instruction encoding (property) condition_i ) Mapping relation between maneuvering time (parameter).
For example, referring to fig. 5, when camera number 96, i.e., the broad camera, is selected, the current task includes a broad camera plus electronics task and a broad camera imaging subtask. The execution time of the electron-adding task is at least 30 seconds earlier than the imaging time of the imaging subtask.
And S104, matching a program control instruction mapping table according to program control information of the current task to obtain a program control satellite instruction.
In some embodiments, the task information may also include programming information. The program control information of the current task may include switch identification (ONOFF), antenna type (dtatipe), antenna identification (DTAID), antenna primary backup (fi_dtlc), operation Mode dta_mode, and the like, which may represent information of an operation state of the system when the current task is executed. The programmed information may be used to determine the operating state of the system, such as; working mode, power on, power off, data transmission, pointing direction, etc.
For example, referring to fig. 6, dtatipe=1 is a data transmission antenna, and when the switch flag onoff=1 is set, the data transmission antenna needs to be turned on. The operation Mode dta_mode=0, and the operation Mode of the data transmission antenna may be a playback Mode.
In one example, a satellite may store a plurality of programmed satellite instructions that have been written. The index of at least one program-controlled satellite instruction can be obtained by matching the program-controlled instruction mapping table according to the attribute information for representing the working state of the system. And then calling the stored program-controlled satellite instruction according to the index of the program-controlled satellite instruction.
Similarly, the programmed instruction map may be stored in the satellite in the form of equation (12) below.
Wherein, the Instruction represents a program control Instruction mapping table and property condition_i In order to determine the characteristic value corresponding to the attribute information such as the judging condition DTAType, DTAID, fi _DTLC of the index of the program-controlled satellite instruction, encoding is the characteristic value of the index of the program-controlled satellite instruction obtained according to the attribute information.
For example, referring to fig. 6, when onoff=1, dtatipe=1, dtaid=1, fi_dtlc=0, program-controlled satellite instructions with indexes 10, 16, 6, 7 in sequence are matched, and these 4 instructions can be used to indicate in sequence: the data transmission system executes the start-up of the ground data transmission phased array antenna 1, the data transmission system executes the pointing of the data transmission phased array waves to the ground station 1, the data transmission system executes the direct-through of the X microwave switch 1, and the data transmission system executes the direct-through of the X microwave switch 2.
S105, generating a satellite imaging task instruction sequence according to the task basic information, the system, the execution content and the constraint condition.
For example, if the current task includes multiple subtasks, the satellite imaging task instruction sequence may include multiple instructions.
For example, a sequence of satellite imaging task instructions may be used to instruct the system to perform a current task based on execution subject to constraints.
In some embodiments, if the mapping table of the task system is not matched to the mapping table of the program control instruction (i.e. not matched to the program control system), the system for executing the current task, the execution content of the current task, the constraint condition of the current task, the task information of the current task, and the satellite instruction template may be directly filled in to obtain the satellite imaging task instruction sequence according to the steps S101-S103.
In one possible implementation, the satellite instruction templates may include a plurality of modules, and the instructions corresponding to each sub-task may fill in information of the corresponding module according to the system executing the sub-task.
For example, referring to fig. 7, the satellite instruction templates may include instruction block time, instruction block code, task ID, control system module 701, visible and infrared camera module 702, wide camera module 703, and data antenna module 704.
In one example, the task ID in the satellite instruction template may be filled in according to the task ID in the task information. According to the execution time and execution duration of each subtask in the execution content of the current task and the constraint conditions of the current task, the time and duration in the visible camera and infrared camera module 702, the wide camera module 703 and the data transmission antenna module 704 are filled in. The mode in the broad camera module 703 is filled in according to the camera imaging category in the execution of the current task. The control mode in the control system module 701 and the mode in the data transmission instruction module 704 are filled in according to the operation mode of the system in the execution content of the current task. The instruction block code is filled in according to the system executing the subtask. The numbers in the visible camera and infrared camera module 702 are filled in according to the camera numbers in the current task. And filling in instruction block time according to the activation time in the task information and the constraint condition of the current task.
For example, referring to fig. 7, if the task ID of the current task is 1 and includes 2 subtasks, two lines of contents may be filled in the satellite command template according to the above method. The first subtask is executed by the control system, the control mode of the control system is the active push-broom, the code of the active push-broom can be filled into 701, the task ID is filled into 1, and the instruction block code is filled into the instruction block code 93 of the control system. Since the maneuver time of the current task is 10:00:02, the task lead time of the subtask is 2 seconds, and the instruction block time is 10:00:00. The code corresponding to 10:00:00 can be written to the instruction block time. The remaining values in the row of instructions corresponding to the subtask may be filled in as default values, e.g., 0.
For example, referring to fig. 7, another subtask is performed by a visible camera with camera number 96. The camera number 96 may be filled in to the camera number in 702. The execution time of the current task is 10:00:00, the duration is 120 seconds, the post-task time of the subtask is 30 seconds, and the time in 702 can be filled in as a code corresponding to 10:00:00, and the duration is filled in as 150. The maneuver time of the current task is 9:59:55, the maneuver lead time is 5 seconds, and codes corresponding to 9:59:50 can be filled in to the instruction block time. The task ID is filled in to 1, and the instruction block code is filled in to the instruction block code 94 corresponding to the visible camera. The remaining values in the row of instructions corresponding to the subtask may be filled in as default values, e.g., 0.
In other embodiments, if the program control system is matched according to the task system template, the system for executing the current task obtained in steps S101-S103, the execution content of the current task, the constraint condition of the current task, the task information of the current task, and the satellite instruction template may be directly filled in to obtain the service satellite instruction. And filling in a satellite instruction template according to the index of the program-controlled satellite instruction, the task information of the current task and the constraint condition of the current task to obtain the program-controlled satellite instruction. Finally, the program-controlled satellite instructions and the service satellite instructions together form a satellite imaging task instruction sequence (see 700 in fig. 7) of the current task.
The method for filling out the service satellite instruction is the same as the method for filling out the satellite instruction when the program control system is not matched, except that the service satellite instruction is obtained.
For example, the task ID in the satellite instruction template may be filled in according to the task ID in the current task information. And filling out the instruction block codes according to the indexes of the program-controlled satellite instructions. And filling in instruction block time according to the maneuvering time of the current task and the constraint condition of the current task.
For example, referring to fig. 7, the fill task ID is 1 and the instruction block codes of the four subtasks performed by the programming system are sequentially filled in 10, 16, 6, 7. Because the task lead time of the four subtasks is 6 seconds, 4 seconds, 1 second and 0 seconds (i.e. the four subtasks do not need to be executed in advance), the instruction block time of the four subtasks is sequentially filled in as follows: 9:59:49, 9:59:51, 9:59:54, 9:59:55.
