Description

Technical Field

[0001] The present invention belongs to the field of collaborative planning of heterogeneous platform tasks for space target observation systems, and specifically relates to a long-term collaborative task planning platform and method for multi-means detection and tracking of wide-area targets throughout the celestial sphere. Background Art

[0002] Since humans launched man-made objects into space in the 1950s, the value of satellites in the civil and commercial fields has been continuously explored. People's convenient lives are inseparable from the data and information provided by satellites. However, due to various accidents or plans, there are also space debris left in orbit, polluting the space environment. At present, due to the immaturity of technology, it is impossible to clean up these space debris efficiently. The current measures are to monitor and track some space debris and let satellites passively avoid collisions when there is a risk of collision. However, due to its own capacity constraints, a single type of observation and tracking platform cannot meet the long-term and large-scale observation requirements of users. The lack of coordinated and coordinated cooperation of multiple observation resources will also lead to problems such as low completion of observation tasks and high resource consumption. Using multiple means to observe and track targets in the entire celestial sphere, and mobilizing various observation resource platforms to coordinate and complement each other to complete the observation tasks, can achieve heterogeneous resource complementarity and complete the observation plan more efficiently and satisfactorily. Summary of the invention

[0003] The purpose of the present invention is to provide a long-term collaborative task planning platform and method for multi-means detection and tracking of wide-area targets throughout the celestial sphere.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] A long-term collaborative task planning platform for multi-means detection and tracking of wide-area targets in the entire celestial sphere, including a target management module, a multi-detection resource management module, a multi-platform collaborative planning module and a task planning module;

[0006] The target management module is used to receive the instantaneous orbit information and priority of the target group input by the user, perform orbit recursion, and obtain the real-time position and speed information data of the target, which is used to calculate the visible window of each observation resource platform to the target in the multi-platform collaborative planning module. The user customizes the guidance order of each observation resource platform to provide data for platform task planning; the observation resource platforms include space-based satellite observation platforms, land-based optical platforms, radar ground station observation platforms and sea-based mobile observation platforms; the multi-detection resource management module is used to model according to the own attributes and capability indicators of each observation resource platform, provide a basis for calculating the visible window of the task, and receive the execution status of each observation resource platform task returned by the task planning module, analyze and organize the real-time changes of the monitored resources and notify the multi-platform collaborative planning module;

[0007] The multi-platform collaborative planning module is used to receive basic data sent by other modules, calculate the visible time window of each observation resource platform to the target according to the target observation requirements, the user-customized guidance order of each observation resource platform and the capabilities of each observation resource platform, and send the observation task to the task planning module using the task allocation method;

[0008] The task planning module is used to comprehensively consider the task completion and the utilization rate of the observation resource platform. At the same time, it retains the automatic adjustment interface in the long-term task planning process, formulates plans for each observation resource platform, monitors the execution of tasks on each observation resource platform, and sends real-time position and speed information to the multi-detection resource management module.

[0009] A long-term collaborative task planning method for multi-means detection and tracking of wide-area targets in the entire celestial sphere, the specific steps are as follows:

[0010] Step 1: The user inputs the orbit information of the target group to be observed and tracked in the entire celestial sphere into the target management module for orbit recursive calculation to obtain the target's real-time position and velocity information data; at the same time, the observation task priority is input and the guidance order of each observation resource platform is customized; the observation resource platforms include space-based satellite observation platforms, land-based optical platforms, radar ground station observation platforms and sea-based mobile observation platforms;

[0011] Step 2: The multi-detection resource management module models each observation resource platform that can be mobilized according to its own attributes and capability indicators;

[0012] Step 3: The multi-platform collaborative planning module receives the real-time position and speed information data of the target group obtained in step 1, and calculates the visible time window of each observation resource platform to the target according to the observation resource platform model in step 2; forms an observation task set, sorts the observation tasks by priority, and sends the observation tasks to the task planning module through the task allocation method according to the guidance order of each observation resource platform customized by the user;

[0013] Step 4: According to step 3, the task planning module receives the observation task set sent by the multi-platform collaborative planning module. The specific steps are as follows:

[0014] Step 4.1: Select the high-orbit target observation and tracking task. The user formulates a task that does not conflict with other task windows and meets the high-orbit target observation strategy;

[0015] Step 4.2: The user chooses whether to enable the mid- to long-term task planning adjustment in the task planning module. The task planning module searches for targets that have not been observed due to low priority, and gradually increases the priority of the target until all targets are observed within the scenario time of the task planning;

[0016] Step 4.3: The task planning module plans tasks according to the load of each observation resource platform, checks whether there are remaining observation resource platforms to supplement the remaining tasks, and sends the real-time status of each observation resource platform monitored to the multi-detection resource management module.

[0017] Furthermore, if the booting order of each observation resource platform is not customized in step 1, the default booting order of the observation resource platform is: space-based satellite observation platform, land-based optical platform, radar ground station observation platform and sea-based movable observation platform.

[0018] Furthermore, step 2 mainly considers the constraints of each observation resource platform when calculating the visible window for targets in the entire celestial sphere and its own ability to monitor targets in parallel.

[0019] The beneficial effects of the present invention are:

The present invention uses a collaborative task planning method to schedule various types of observation resource platforms for efficient collaboration and complementarity, completes the observation and tracking task planning for multiple targets in the entire celestial sphere, and outputs the observation plan of each observation resource platform; in the overall task planning process, special treatment is performed on high-orbit targets to ensure that other observation needs are not affected and the overall observation plan can be completed efficiently; in the case of large observation demand and long task planning scenario time, a long-term task planning system automatic adjustment interface is provided to ensure that all targets can be observed and tracked in the long-term task planning, ensuring the completion of the entire observation plan. The present invention has real-time monitoring function and a long-term task planning adjustment interface, which ensures that the overall observation resource platform can operate stably and efficiently execute the formulated observation task plan.

[0024] The present invention is further described below in conjunction with the accompanying drawings.

[0025] like Figure 1 As shown, the present invention provides a long-term collaborative task planning platform for multi-means detection and tracking of wide-area targets throughout the celestial sphere, including a target management module 1, a multi-detection resource management module 2, a multi-platform collaborative planning module 3 and a task planning module 4.

[0026] like Figure 2 As shown, the present invention is a heterogeneous platform task planning method for long-term multi-means observation resource management. First, the operator imports the target group information that needs to be observed and tracked in the target management module 1, and formulates the task priority and the guidance order of each observation resource platform; the multi-detection resource management module 2 models each observation resource platform, considering the constraint attributes of the observation resource platform itself and the multi-target parallel observation capability; the multi-platform collaborative planning module 3 calculates the visible window set of the observation task according to the received data, and considers the task priority and the guidance order of the observation resource platform formulated by the user, performs preliminary task allocation, and sends it to the task planning module 4; the task planning module 4 divides the newly created window processing according to the task allocation result sent by the multi-platform collaborative planning module 3, considering the particularity of the visible window of the high-orbit target, and can automatically adjust the long-term task planning at the same time to ensure that all targets can be observed within the scene time of the task planning. Finally, the load constraints of the space-based satellite observation platform, the land-based optical, radar ground station observation platform and the sea-based mobile observation platform are analyzed, and supplementary planning is performed according to the remaining resources, and the task planning is finally completed; its implementation process is as follows:

[0027] Step 1: The user inputs the orbit information of the target group to be observed and tracked in the entire celestial sphere, and the target management module 1 performs orbit recursive calculation. The user can also input the observation task priority and customize the guidance order of each observation resource platform. If the guidance order of each observation resource platform is not customized, the default observation resource platform guidance order is used to guide the land-based optical and radar ground station observation platforms and the sea-based mobile observation platform for the space-based satellite observation platform;

[0028] Step 2: The multi-detection resource management module 2 models the observation resource platforms that can be mobilized, including space-based satellite observation platforms, land-based optical and radar ground station observation platforms, and sea-based mobile observation platforms. It mainly considers the constraints of each observation platform when calculating the visible window of the entire celestial sphere target and its own ability to monitor targets in parallel;

[0029] Step 3: The multi-platform collaborative planning module 3 receives the real-time position and speed information of the target group obtained in the first step, considers the models of each observation resource platform obtained in the second step, calculates all visible time windows of each observation resource platform for the target group, forms an observation task set, sorts the observation tasks by priority, and sends the observation tasks to the task planning module 4 using the task allocation method according to the observation resource platform guidance order specified by the user; for example: according to the default observation resource platform guidance order, first determine the task set that can be completed by the space-based satellite observation platform, then determine whether there are tasks that can be completed by the land-based optical and radar ground observation platforms in the remaining task set screened by the space-based satellite observation platform, and finally determine whether there are tasks that can be completed by the sea-based mobile platform in the remaining task set screened by the land-based optical and radar ground observation platforms;

[0030] Step 4.1: The task planning module 4 receives the task set sent by the multi-platform collaborative planning module 3, and first picks out the high-orbit target observation and tracking task, because the visible window of the target in the higher orbit is generally longer and does not require continuous observation. If the task planning is directly carried out without processing, it will lead to resource waste caused by the long-term occupation of some observation resource platforms, other observation tasks cannot be executed, and the overall task completion is low. Therefore, the present invention retains the high-orbit target task processing interface, and the user can formulate the observation strategy of the high-orbit target task. For example, the target is observed for 5 minutes every 2 hours. The task planning module 4 will split the longer visible window of the high-orbit target and re-formulate tasks that do not conflict with other task windows and meet the high-orbit target observation strategy;

[0031] Step 4.2: The user chooses whether to enable the long-term task planning adjustment in the task planning module 4. The significance of this is that if there are many observation tasks and the observation time is long, some low-priority observation tasks may not be executed, resulting in some targets not being observed and tracked. When the long-term task planning adjustment is enabled, the task planning module 4 will find out whether there are some targets that have never been observed due to their low priority, and then gradually increase the priority of the target, so as to ensure that all targets can be observed within the scenario time of the task planning.

[0032] Step 4.3: The task planning module 4 plans the formed observation task set by considering the load conditions of each observation resource platform, and checks whether there are remaining observation resource platforms that can be used to supplement the remaining tasks. At the same time, the real-time conditions of each monitored observation resource platform are sent to the multi-detection resource management module 2.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
