[0064] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0065] The method provided in the embodiment of the present invention can be applied to satellites such as communication satellites and remote sensing satellites. The embodiment of the present invention does not impose any limitation on the specific type of satellite. Figure 1 A schematic diagram of a flow chart of a satellite command generation method provided by an embodiment of the present invention; Figure 1 As shown, the method comprises:

[0066] S101: Obtain user demand information; the user demand information includes at least one demand condition;

[0067] In a specific embodiment, there may be a user operation interface at the ground station for the user to input the required information, and the user inputs the required conditions and parameters through the operation interface. For example, the user inputs through the operation interface that when a ship numbered 710001010 enters an area with a radius of 100 meters and a point at longitude -40.52859 and latitude -22.4120 as the center, the ship is photographed for 3600 seconds.

[0068] S102: Determine a corresponding policy file according to the user requirement information; the policy file includes a condition template corresponding to the requirement condition in the user requirement information, and identification information of an execution action set file corresponding to each condition template; the execution action set file includes identification information of an instruction set file corresponding to each execution action;

[0069] In the present invention, multiple strategy files, execution action set files, model files and instruction set files are generated in advance according to various user requirements. In practical applications, the corresponding strategy files, execution action set files, model files and instruction set files can be determined according to the type of user requirements. Among them, the strategy file includes one or more condition templates (configurable parameters) corresponding to the user requirements, and also includes the identification of the execution action set triggered when one or some conditions are met, which is used to associate the conditions with the execution actions. The execution action set file includes the action task identification and execution order of each device or payload on the satellite. The model file is an execution action, and the actions that need to be logically calculated and algorithmically processed are encapsulated into corresponding model files. The identification of the action task for logical calculation and algorithm processing in the execution action set file is the identification of the model file. An instruction set file includes a set of all instructions when a satellite device or payload performs a certain action task, and includes the instruction execution order.

[0070] S103: According to the parameters of the demand conditions in the user demand information, the parameters of the condition template in the policy file are configured, and according to the identification information of the execution action set file corresponding to each condition template and the identification information of the instruction set file corresponding to each execution action in the execution action set file, the execution action set file corresponding to each condition template and the instruction set file corresponding to each execution action in the execution action set file are obtained to obtain the target policy file;

[0071] For example, according to user needs, when a ship numbered 710001010 enters an area with a radius of 100 meters and a point at longitude -40.52859 and latitude -22.4120 as the center, the ship is photographed for 3600 seconds, and the parameters of the conditional template in the parameter configuration strategy file can be configured.

[0072] In this embodiment, the execution action set file and the instruction set file corresponding to the user demand can be included in the target strategy file together with the condition template, so that only one target strategy file needs to be uploaded to the satellite.

[0073] Of course, in other embodiments, the execution action set file and the instruction set file corresponding to the user demand may not be included in the target policy file, and the target policy file only includes the condition template corresponding to the user demand (the condition template includes the identification information of the execution action set file corresponding to the user demand, and the execution action set file includes the identification information of the instruction set file corresponding to each execution action). In this way, it is necessary to upload the target policy file, the execution action set file and the instruction set file corresponding to the user demand to the satellite.

[0074] For example, for user requirements: if the ground in area A is on fire, take remote sensing images.

[0075] The target strategy file includes: Condition 1, relevant information of area A, such as the coordinate points of area A; Condition 2, fire on the ground. The associated execution action set files include: infrared payload shooting, infrared image fire identification (model file), ground station fire emergency alarm. The associated instruction set files include: start the infrared payload when reaching XX coordinates, swing the infrared payload to XX deflection angle, XX pitch angle, start the data storage payload and image processing payload (image identification, whether there is a fire), and start the communication payload when reaching XX coordinates (send an emergency alarm to the ground station).

[0076] S104: Upload the target strategy file to the satellite; when the satellite's onboard computer receives the target strategy file, it determines the target satellite device and / or target payload and its corresponding instructions based on the execution action set file corresponding to each condition template in the target strategy file and the instruction set file corresponding to each execution action in the execution action set file, and sends each instruction to each target satellite device and / or target payload respectively, so that each target satellite device and / or target payload executes its corresponding instruction respectively.

[0077] In the field of satellites, payload refers to the instruments, equipment or systems carried on satellites to complete specific tasks. There are many types of payloads on satellites, such as optical cameras and synthetic aperture radars for earth observation, transponders and antennas for communication, atomic clocks and navigation signal transmitters for navigation and positioning, particle detectors and magnetic field meters for scientific exploration, etc.

[0078] In the embodiment of the present invention, when there are logic calculation actions and / or algorithm processing actions in the execution action set file corresponding to the condition template in the policy file, the logic calculation actions and / or algorithm processing actions correspond to the identification information of the corresponding algorithm model;

[0079] When the execution action set file of the condition template corresponding to the requirement condition in the user requirement information includes a logic calculation action and / or an algorithm processing action, the target strategy file corresponding to the user requirement information also includes identification information of the algorithm model corresponding to the logic calculation action and / or the algorithm processing action; the method provided by the embodiment of the present invention also includes:

[0080] The model file is uploaded to the satellite; the satellite's onboard computer can obtain the target algorithm model from the model file according to the identification information of the algorithm model in the target strategy file, and input the data collected by the satellite device and / or payload into the target algorithm model for calculation, and obtain the calculation results.

[0081] In an embodiment of the present invention, the conditional templates in the strategy file are divided into remote sensing trigger class, IoT data acquisition data trigger class, ship automatic identification signal trigger class (AIS signal trigger class) and aircraft automatic identification signal trigger class (ADS-B signal trigger class) according to the corresponding load types and load attribute parameters; the execution action set files corresponding to the conditional templates in the strategy file are divided into remote sensing execution class and IoT instruction execution class.

[0082] AIS signal is the signal sent by the ship's automatic identification system (Automatic Identification System). ADS-B signal is the Automatic Dependent Surveillance-Broadcast signal, which is an aircraft operation monitoring technology based on the global satellite positioning system and air-to-ground and air-to-air data link communications.

[0083] Remote sensing triggering is a method that uses remote sensing technology to trigger specific events. IoT data acquisition triggering usually refers to the process of starting satellite data collection through certain conditions or events in the IoT environment. AIS signal triggering usually refers to triggering satellites to collect, analyze and take corresponding measures such as sounding alarms and conducting traffic management through specific conditions or events, such as when a ship enters a specific geographical area, reaches a specific speed or heading change range, or the distance from other ships reaches a preset threshold. ADS-B signal triggering refers to starting the satellite's response or processing of Automatic Dependent Surveillance-Broadcast (ADS-B) signals based on specific conditions, such as when an aircraft enters a specific airspace, approaches a specific airport, reaches a dangerous threshold with other aircraft, or according to time intervals, flight plans and other set conditions.

[0084] In a specific embodiment, the remote sensing trigger condition template includes the following parameters: coordinates of the shooting area, shooting time, target load, side swing requirements, target algorithm model, and conditions for triggering the execution of actions; the IoT data acquisition trigger condition template includes the following parameters: target terminal, target algorithm model, and conditions for triggering the execution of actions; the ship automatic identification signal trigger condition template includes the following parameters: target ship information and conditions for triggering the execution of actions; the aircraft automatic identification signal trigger condition template includes the following parameters: target aircraft information and conditions for triggering the execution of actions; the remote sensing execution class includes the following parameters: coordinates of the execution area, shooting time, target load, and target execution action set file; the IoT command execution class includes the following parameters: command data of the target terminal.

[0085] Under the remote sensing trigger type, it mainly includes the description of the remote sensing monitoring area (such as the coordinate points of the monitoring area, the shooting time of the monitoring area, etc.), shooting requirements (such as using a specific load, side swing requirements, etc.), which algorithm model is used to process the shooting results, and what kind of judgment needs to be made on a certain parameter in the result processed by the algorithm model to trigger the execution action (for example, the actual value of the infrared temperature parameter in the result processed by the algorithm model needs to be compared with the threshold. When the actual value of the infrared temperature parameter is greater than the threshold, the alarm action is triggered).

[0086] The IoT data acquisition trigger type mainly includes the description of specific parameters of a specific terminal (i.e., the target terminal) (which parameter or parameters on which terminal are to be collected), which algorithm model is used to process the above terminal data, and what kind of judgment is required for a certain parameter of the processed data in order to trigger it.

[0087] Under the AIS signal trigger type, it mainly includes the description of the specific ship and what kind of area judgment is required for the specific location of the above-mentioned ship in order to trigger it.

[0088] Under the ADS-B signal trigger type, it mainly includes the description of the specific aircraft and what kind of area judgment is required for the specific location of the above aircraft in order to trigger it.

[0089] Under the remote sensing execution type, it mainly includes the description of the remote sensing shooting execution area (such as the coordinate points of the execution area, the shooting duration of the execution area, etc.), the shooting task (such as using a specific payload, executing an action set file, etc.);

[0090] The IoT command execution type mainly includes the description of specific commands for specific terminals.

[0091] In a specific embodiment, the step of determining the corresponding policy file according to the user demand information may include:

[0092] According to the load type and load attribute parameters corresponding to each demand condition in the user demand information;

[0093] Determine the condition template type corresponding to each requirement condition; the condition template types include: remote sensing trigger condition template, IoT data acquisition data trigger condition template, ship automatic identification signal trigger condition template and aircraft automatic identification signal trigger condition template;

[0094] According to the execution action set file corresponding to each condition template, determine the execution action type corresponding to each requirement condition; the execution action type includes remote sensing execution type and IoT instruction execution type;

[0095] According to the condition template type and execution action type corresponding to each requirement condition in the user requirement information, the policy file corresponding to the user requirement information is determined.

[0096] In practical applications, the model file includes a shake sensing processing algorithm model and an IoT model; the shake sensing processing algorithm model is applied to remote sensing triggering scenarios; and the IoT model is applied to IoT data acquisition triggering scenarios.

[0097] In actual applications, the policy file can be described in JSON format. JSON is a lightweight data exchange format. It is based on a subset of JavaScript and uses a text format that is completely independent of the programming language to store and represent data. It has the following advantages: concise and clear hierarchical structure, easy for people to read and write, easy for machines to parse and generate, and can effectively improve network transmission efficiency.

[0098] In an embodiment of the present invention, the condition template in the strategy file includes two parts of description: a trigger description and an actuator description. The trigger description is the trigger condition description, and the actuator description is the execution action description. In the present invention, there are 4 types of triggers: remote sensing trigger, IoT data acquisition trigger, AIS signal trigger and ADS-B signal trigger, wherein each type of trigger corresponds to a different data structure. There are 2 types of execution actions: remote sensing execution and IoT instruction execution, wherein each type of actuator corresponds to a different data structure. According to different types of user needs, these 4 types of triggers and 2 types of actuators can be arbitrarily combined according to actual needs to obtain the target strategy file.

[0099] After uploading the target strategy file and the algorithm model file (if there are no logical calculation actions and / or algorithm processing actions in the execution action set file corresponding to the user's needs, the algorithm model file is not required) to the satellite, the satellite will trigger the trigger in the target strategy file through the satellite service computer (that is, the trigger condition is triggered), and when the trigger is successfully triggered, the actuator content is converted into a satellite instruction, and the satellite service computer distributes the corresponding satellite instructions to the corresponding satellite devices and payloads for execution, where the actuator content is the execution action set file corresponding to the user's demand information and the instruction set file corresponding to each execution action in the execution action set file.

[0100] In summary, the method provided by the embodiment of the present invention can achieve obtaining user demand information; determining the corresponding strategy file according to the user demand information; configuring the parameters of the condition template in the strategy file according to the parameters of the demand conditions in the user demand information, and obtaining the execution action set file corresponding to each condition template and the instruction set file corresponding to each execution action in the execution action set file according to the identification information of the execution action set file corresponding to each condition template and the identification information of the instruction set file corresponding to each execution action in the execution action set file, to obtain the target strategy file; uploading the target strategy file to the satellite; and enabling the satellite's onboard computer to determine the target satellite device and / or target payload and its corresponding instructions according to the execution action set file corresponding to each condition template in the target strategy file and the instruction set file corresponding to each execution action in the execution action set file when receiving the target strategy file, and to send each instruction to each target satellite device and / or target payload respectively, so that each target satellite device and / or target payload respectively executes its corresponding instruction. Obviously, the method provided by the embodiment of the present invention pre-abstracts the strategy file, the execution action set file, the instruction set file and the model file according to various user requirements, and realizes the modular management of the whole process from user requirements to satellite instructions based on the above files, and realizes the automatic generation of satellite instructions according to user demand information, thereby solving the problem of low efficiency and time-consuming and labor-intensive generation of satellite instructions in the prior art due to the need to manually design and write satellite instructions for each shooting requirement proposed by the user. In addition, since the method provided by the present invention is modularly managed, when the type of user requirements is updated, it is only necessary to adaptively update and expand the conditional template, execution action set file, instruction set file or model file in the strategy file, so the method provided by the present invention has better adaptability and flexibility.

[0101] The following is a practical example to further illustrate the process of obtaining the target policy file in the method provided by the embodiment of the present invention.

[0102] For example, user demand information is: when the ship numbered 710001010 enters area 1 (the area with a point at longitude -40.52859 and latitude -22.4120 as the center and a radius of 100 meters), the ship is photographed for 3600 seconds. When the ship numbered 1099090909 does not enter area 2 (the area with a point at longitude 19.120 and latitude 18.120 as the center and a radius of 1000 meters), but enters area 1, the ship is photographed for 3600 seconds.

[0103] According to the user demand information, the trigger contained in the target strategy file is determined to be AIS signal trigger, and the actuator is shake sensing execution. The description of the first remote sensing monitoring area is:

[0110]

[0111] When the ship numbered 1099090909 does not enter area 2 but enters area 1, the triggered execution action is:
