[0067] 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.

[0068] The satellite in the present invention may be a communication satellite, a remote sensing satellite, or the like, and the embodiments of the present invention do not impose any restrictions on the specific type of satellite. Figure 1 As shown, the self-defined task scheduling system provided by the embodiment of the present invention includes: a business management module 101, a task execution module 102 and a data processing module 103;

[0069] The business management module 101 is used to receive user needs; analyze the user needs to obtain task needs and data needs corresponding to the user needs; send the task needs to the task execution module 102 and the data needs to the data processing module 103 respectively.

[0070] User needs include remote sensing photography of XX area to obtain data that meets XX conditions.

[0071] The management scope of the business management module 101 mainly includes: remote sensing business management, Internet of Things service management, space-ground linkage strategy management, standard product services, delivery resource center services and data publishing services.

[0072] The business management module 101 analyzes the task requirements and data requirements according to the user requirements, and then sends the task requirements to the task execution module 102 and the data requirements to the data processing module 103. The task requirements include what type of satellite (such as high-definition satellite), what type of payload (such as high-definition remote sensing camera), target area, and the latest completion time; the data requirements include coordinate positioning processing of remote sensing image data, slicing processing of remote sensing image data, filtering processing of remote sensing image data, and clarity processing of remote sensing image data.

[0073] The task execution module 102 is used to receive the task requirements sent by the business management module 101; analyze the task requirements and determine the execution task sequence corresponding to the task requirements; convert the execution tasks in the execution task sequence into satellite instructions in sequence, and send the satellite instructions to the satellite, so that the satellite executes the satellite instructions and sends the collected business data to the data processing module 103.

[0074] The task execution module 102 is mainly used to analyze the task requirements and plan an orderly execution task sequence according to the task requirements. Among them, the execution task is used to plan what instructions are to be sent to the satellite. For example, the execution task is: what satellite is scheduled to shoot the target area in what time window. More specifically, the orderly execution task sequence (task chain) of the satellite is: at XX time point XX satellite turns on the remote sensing camera, at XX time point the remote sensing camera swings to XX angle, at XX time point the communication payload is turned on, at XX time point the remote sensing camera starts shooting, at XX time point the measurement and control digital transmission payload is turned on, and at XX time point the remote sensing data is transmitted to the ground station through the communication payload and the measurement and control digital transmission payload. The orderly execution task sequence is converted into satellite instructions in turn and sent to the target satellite, so that the target satellite executes the instructions and obtains business data.

[0075] The data processing module 103 is used to receive the business data sent by the satellite, wherein the business data sent by the satellite is various types of business data, for example, remote sensing data taken by the satellite on a certain area at a certain time point. The processing of each type of business data after being transmitted to the ground station involves the situation where different algorithms are processed alternately in sequence. The data processing module 103 provided by the embodiment of the present invention supports the algorithm used for each business data processing in the ground station in series in the form of a task instance by means of a custom task scheduling method, and sequentially schedules each algorithm to complete all algorithm processing to obtain the target processing result.

[0076] Specifically, the data processing module 103 includes a data transmission analysis submodule 1031 , a management submodule 1032 and a scheduling submodule 1033 .

[0077] The data transmission analysis submodule 1031 is used to receive business data sent by the satellite; analyze the business data according to the business identification information in the business data and the data analysis method corresponding to each business identification information, remove the frame structure in the business data, and obtain the original data; according to the communication protocol corresponding to the target business data, extract the target business data from the original data, and send the target business data to the management submodule 1032.

[0078] In practical applications, the data transmission analysis submodule 1031 is mainly used to receive the business data sent by the satellite, and analyze the business data according to the business identification information in the business data and the data analysis method corresponding to each business identification information. The frame structure in the earth-to-space transmission (transmission between the satellite and the ground station) in the business data is removed to restore the original data content. After the data is restored, the data transmission analysis submodule 1031 will store and back up all the restored original data. At the same time, according to the communication protocol corresponding to the target business data, the target business data (for example, the imaging data of each remote sensing camera, the Internet of Things data, the AIS signal data, the ADS-B signal data, etc.) will be extracted from the original data and the target business data will be sent to the management submodule 1033 for further processing, wherein the business data includes the business identification information.

[0079] The management submodule 1032 is used to receive the data requirements sent by the business management module and the target business data sent by the data transmission analysis submodule; determine the processing task sequence corresponding to the data requirements according to the type of data requirements; analyze the data requirements based on the processing task sequence, determine the processing units required to realize the data requirements, and the triggering conditions, triggering timing and execution mode of each processing unit; configure each processing unit according to the triggering conditions, triggering timing and execution mode of each processing unit, and obtain the workflow of each processing unit corresponding to the data requirements; wherein, each type of data requirement is configured with a processing task sequence; and one processing task is processed by one processing unit;

[0080] In actual application, in the management submodule 1032, a processing task sequence is configured in advance according to the type of data demand for each type of data demand. The management submodule 1032 will determine the processing task sequence corresponding to the data demand according to the type of data demand, and analyze the data demand based on the processing task sequence corresponding to the data demand, determine the processing unit required to realize the data demand, and the triggering condition, triggering time and execution mode of each processing unit; configure each processing unit according to the triggering condition, triggering time and execution mode of each processing unit, and obtain the workflow of each processing unit corresponding to the data demand; wherein, based on the processing task sequence corresponding to the data demand, analyze the data demand, determine the processing unit required to realize the data demand, and the triggering condition, triggering time and execution mode of each processing unit; configure each processing unit according to the triggering condition, triggering time and execution mode of each processing unit, and obtain the workflow of each processing unit corresponding to the data demand, that is, the process of instantiating the processing task sequence according to the data demand.

[0081] In practical applications, for each data requirement, after determining the processing task sequence according to the type of the data requirement, an independent task instance will be formed based on the specific content of the data requirement based on the processing task sequence, and the specific execution process of the task instance will be limited according to the original configuration content of the processing task sequence, that is, the specific execution process of the task instance will be limited according to the execution flow pre-configured by the processing task sequence. For example, the data requirement is a remote sensing imaging data requirement, and the processing task sequence is determined according to the type of the data requirement as: coordinate alignment, image cutting, image filtering, and image correction. Based on the processing task sequence as a blueprint and based on the specific requirements of the remote sensing imaging data requirement, the processing units corresponding to each processing task in the processing task sequence are configured respectively. For example, according to the specific requirements of the remote sensing imaging data requirement, the processing unit corresponding to the image cutting link in the processing task sequence is configured, and the triggering conditions, triggering timing and execution mode (that is, the processing algorithm adopted) of the processing unit are configured to form an independent task instance, wherein the specific execution process of the task instance is: coordinate alignment, image cutting, image filtering, and image correction, and one processing task is completed by one processing unit.

[0082] There are different types of processing units. Processing units cannot independently support the execution of task instances, and can only complete the given tasks through combination. In a specific embodiment, processing units can be divided into the following types according to their functions: processing units that update the task status according to different processing processes, processing units that split multiple results into different task instances and independently initiate operations, processing units that automatically pause the current task instance under certain circumstances and wait for system review, processing units that perform manual intervention processing under certain circumstances, processing units that call specified algorithms or parameters to process data, processing units that store processing results in specified locations, processing units that notify push resources of completion, processing units that check data validity, and so on. The same type of processing units can be repeatedly configured in different task sequences. According to actual data requirements, the same type of processing units with different parameter contents can play a role that is more suitable for this task instance.

[0083] After instantiating the processing task sequence according to data requirements and obtaining the workflow of each processing unit, the triggering conditions, triggering timing and execution mode of each processing unit are determined. Each time the same or different instantiated processing task sequence is executed, the pre-configured processing units execute different processing units in different triggering conditions in a synchronous, asynchronous, serial, parallel, or serial-parallel hybrid manner according to the established workflow.

[0084] The management submodule 1032 can also be used to manage the algorithm files of the algorithms used by each processing unit, mainly to maintain the algorithm files and algorithm parameters, and to perform version management on the algorithms to ensure that different scheduling routes can use the corresponding algorithms and can be called up and run normally.

[0085] The scheduling submodule 1033 is used to obtain the workflow of each processing unit corresponding to the data demand from the management submodule, and call each processing unit in sequence to process the target business data according to the workflow of each processing unit corresponding to the data demand to obtain the target processing result.

[0086] The scheduling submodule 1033 is also used to confirm the execution order of each processing unit according to the workflow of each processing unit corresponding to the data demand, and before calling each processing unit according to the execution order, first determine the parameters required by the processing unit according to the execution method of each processing unit, and obtain the parameters required by the processing unit from the data demand and / or the execution result of the previous processing unit, and when the processing unit is called, send the parameters required by the processing unit to the processing unit.

[0087] In actual applications, the business management module 101 is also used to obtain the target processing result of the scheduling submodule 1033 and feed back the target processing result to the user.

[0088] See also Figure 2 , Figure 1 The interaction process between the modules of the system shown and between the modules and the satellite can be:

[0097] S209: The business management module obtains the target processing result from the data processing module and feeds back the target processing result to the user.

[0098] In summary, the system provided by the embodiment of the present invention can realize that for each data demand, after determining the processing task sequence according to the type of the data demand, the processing task sequence will be used as a blueprint, based on the specific content of the data demand, to determine the triggering conditions, triggering timing and execution mode of each processing unit in the processing task sequence, and configure each processing unit according to the triggering conditions, triggering timing and execution mode of each processing unit, so as to instantiate the processing task sequence to form an independent task instance, and obtain the processing unit workflow corresponding to the task instance; and sequentially call each processing unit in the processing unit workflow to process the target business data to obtain the target processing result.
