All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, in the relay satellite measurement and control field, simple data-level backup cannot meet the disaster tolerance requirement, while system-level backup cannot meet the situation that measurement and control data in the relay satellite measurement and control field are complex, and the disaster tolerance reliability cannot be guaranteed.
Based on this, the disaster recovery method and apparatus based on the task scheduling center provided by the embodiments of the present invention can switch disaster recovery when the measurement and control system with higher requirement on the operation data has a fault, normally measure and control the operation data, and ensure the reliability of disaster recovery.
To facilitate understanding of the embodiment, a disaster recovery method based on a task scheduling center disclosed in the embodiment of the present invention is first described in detail.
Fig. 1 is a schematic flowchart of a disaster recovery method based on a task scheduling center according to an embodiment of the present invention.
Referring to fig. 1, a disaster recovery method based on a task scheduling center, which can be implemented in the field of relay satellite measurement and control, is applied to an arbitration center, and includes the following steps:
step S102, user application information is obtained and used for representing task information executed by the task scheduling center.
Here, the user can obtain the current resource situation through the space window of the terminal, and according to the current resource situation, the user application information is provided and sent to the arbitration center.
And step S104, selecting a first target task scheduling center with a normal running state from the plurality of task scheduling centers by performing state detection on the plurality of task scheduling centers.
And step S106, sending the user application information to a first target task scheduling center so that the first target task scheduling center obtains a task planning scheme according to the user application information and the current resource condition.
In a preferred embodiment of practical application, the arbitration center obtains task information required to be executed by the task scheduling centers through user application information, performs state detection on a plurality of task scheduling centers, can select a first target task scheduling center in a normal operation state when a measurement and control system with higher requirement on operation data has a fault, and sends the user application information to the first target task scheduling center to perform normal measurement and control on the operation data of the relay satellite, thereby ensuring disaster tolerance reliability.
Because the relay satellite measurement and control system has a lot of operation data, in order to ensure that excessive pressure is not applied to the task scheduling center, and slow operation delay is caused, the embodiment of the invention also comprises the following method, as shown in fig. 2, comprising:
step S202, the state of a plurality of task scheduling centers is detected.
Step S204, judging whether the plurality of task scheduling centers have abnormal operating states.
If so, the process goes to step S206.
If not, the process goes to step S208.
Step S206, selecting a first target task scheduling center with a normal operation state from the plurality of task scheduling centers, and sending the user application information to the first target task scheduling center.
And S208, selecting a second target scheduling center with less distributed first historical tasks according to the distribution condition of the first historical tasks, and sending the user application information to the second target task scheduling center.
If the number of tasks historically allocated to the first task scheduling center by the arbitration center is 2, and the number of tasks historically allocated to the second task scheduling center is 3, the current task is allocated to the first task scheduling center with the history task allocated less frequently.
In order to further reduce the pressure of the applied task scheduling center, the embodiments of the present invention may also perform allocation according to the pressure condition (the allocation execution condition of the historical tasks) of the task scheduling center when the link is established and/or the management and control information is uploaded.
That is, the embodiment of the present invention may be implemented when the management and control system establishes the link:

The management and control system also establishes a satellite-ground link and a ground link to a third target task scheduling center according to the planning scheme, and simultaneously sends configuration loading results according to the planning scheme and link establishment results to the third target task scheduling center.
The embodiment of the invention can also be used for uploading the control information in the control system:
receiving a control information uploading signal; and selecting a fourth target task scheduling center with less third history task quantity distribution according to the distribution condition of the third history tasks so as to upload the user application information to the fourth target task scheduling center.
It should be noted that, in the embodiment of the present invention, a task scheduling center that performs work may be selected according to the distribution condition of the historical tasks when a link and management and control information are established, or a task scheduling center with low pressure may be selected only when a link is established, or a task scheduling center with low pressure may be selected only when management and control information is uploaded.
As an alternative embodiment, in order to more accurately detect the state of the task scheduling center, step S104 in the foregoing embodiment further includes the following steps:
1. and sending the heartbeat detection signal to a plurality of task scheduling centers in real time.
2. And receiving feedback signals of a plurality of task scheduling centers.
3. And knowing the running states of the plurality of task scheduling centers according to the feedback signal, and further selecting a first target task scheduling center with a normal running state from the plurality of task scheduling centers.
Further, as shown in fig. 3, an embodiment of the present invention further provides a disaster recovery method based on a task scheduling center, which is applied to a first task scheduling center, and includes the following steps:
step S302, receiving user application information sent by an arbitration center;
and step S304, obtaining a task planning scheme according to the user application information and the current resource condition, and sending the task planning scheme to the management and control system so that the management and control system loads and configures according to the task planning scheme.
It should be noted that the method is applied to a case where a first task scheduling center selected from a plurality of task scheduling centers is assumed to be a first target task scheduling center.
Further, in order to ensure that the current task scheduling center can be seamlessly switched to the task scheduling center in a good state when the task scheduling center is abnormal or has a large pressure load, and the scheduling center can process a large number of measurement and control processes and data of the relay satellite in time, the method further includes:
and synchronizing the application data and the management and control information to a second task scheduling center so that the second task scheduling center continues to execute the current task according to the synchronized application data and/or the management and control information.
Alternatively, the first and second electrodes may be,
the method further comprises the following steps:
and synchronizing the application data or the management and control information to the second task scheduling center so that the second task scheduling center continues to execute the current task according to the synchronized application data and/or the management and control information.
The application data is used for completing a current task obtained according to the user application information, and the control information comprises a current resource occupation condition and equipment operation information in the control system.
Therefore, the first task scheduling center serving as the target task scheduling center sends the application data to the management and control center and synchronizes the application data to the second task scheduling center. As an optional implementation manner, when the management and control system uploads the management and control information to the target task scheduling center, the target task scheduling center may also synchronize the management and control information to the second task scheduling center, so as to implement seamless handover.
In the relay satellite measurement and control field, the management and control system may include an operation and control system, a ground station equipment management and control system, and a user center scheduling and control system. The corresponding control information is the corresponding device operation information and the current resource condition in the control system. If so, the ground station equipment management and control system and the user center scheduling management and control system respectively upload equipment fault information, equipment operation parameter information and equipment performance information in the station where the ground station equipment management and control system and the user center scheduling management and control system are located; and uploading the actual resource occupation condition by the operation control system.
In some possible embodiments, the embodiments of the present invention are applied to the relay satellite measurement and control application field, and step S304 includes the following steps:
1. acquiring the current available resource condition;
2. obtaining a resource pre-allocation scheme according to the current available resource condition and the user application information;
3. and performing task planning on the current resources according to the resource pre-allocation scheme to obtain a task planning scheme, and sending the task planning scheme to a management and control system.
Here, the planning and scheduling system in the task scheduling center generates a user requirement, that is, a requirement situation of a user for a resource, according to the user application information, requests a current available resource situation from a resource management system in the task scheduling center, and obtains a resource pre-allocation scheme for the user requirement according to the current available resource situation and the user requirement. And the task scheduling center coordinates resources according to a resource pre-allocation scheme and issues and updates the coordinated current resource condition to the resource management system. And the planning and scheduling system combines the user application and the current resource condition to carry out task planning to obtain a task planning scheme.
The resource pre-allocation scheme can be embodied in a table format of a system page comprising task time, resource types to be used, resource names and task contents, and if 9 points are needed, a satellite A is used for measuring and controlling data B and a channel C is used for transmission. The mission planning scheme can be understood as allocating various resources such as x satellites, y channels and the like obtained according to the resource pre-allocation scheme to z systems or equipment.
In addition, the planning and scheduling system in the target task scheduling center can issue the planning scheme to the corresponding ground station equipment management and control system, operation and control system, user center scheduling management and control system and the rest task scheduling center, so that each management and control system can obtain various corresponding planning parameters. Planning parameters may be understood as a form of a system page table including parameter types such as IP addresses of individual devices that may be modified according to the planned resources.
And the task scheduling center sends a task loading command to the corresponding system in a task period, so that the corresponding control system performs parameter configuration and loading according to the loading command and the planning parameters respectively.

In step S407, the task scheduling center (the first target task scheduling center or the second target task scheduling center) sends the planning scheme and the loading command to the management and control system.
The ground station equipment management and control system loads the received planning parameters into corresponding equipment or a software system for configuration according to planning resources in a task period; the operation control system carries out configuration adjustment on the relay satellite resources according to the received planning parameters in the task time period; and the other task scheduling centers load the received (synchronized) planning parameters (application data) into corresponding equipment or a software system for configuration according to the planning scheme in the task time period.

In step S413, the management and control system establishes a link with the task scheduling center (a third target task scheduling center) according to the planning scheme.
Step S414, the management and control system sends a configuration completion signal to the task scheduling center (the third target task scheduling center) when the link is completed and the configuration is completed.
And the rest task scheduling centers, the ground station equipment management and control system and the operation and control system establish a satellite-ground link and a ground link according to the planning scheme, carry out network opening and feed back the configuration result to the planning and scheduling system of the task scheduling center.
In step S415, the management and control system sends a management and control information uploading signal to the arbitration center.
Step S416, the arbitration center selects a fourth target task scheduling center with a smaller number of assigned third history tasks according to the assignment of third history tasks.
Step S417, the arbitration center sends a management and control information uploading instruction to the management and control system.
In step S418, the management and control system uploads management and control information to the task scheduling center (fourth target task scheduling center).
Here, the management and control information includes a system operation situation formed by the operation and control system feeding back the actual satellite resource occupation result to the integrated network management system in the task scheduling center. And the comprehensive network management system distributes the system operation situation to the resource management system to complete the collection of the actually used relay satellite resource information. The ground station equipment management and control system and the operation and control system report management information such as equipment operation conditions, network operation performance information, user service data guarantee conditions and the like to the comprehensive network management system of the task scheduling center through the northbound interface to form a system operation situation.
The ground equipment management and control system can also report operation data to the task scheduling center, and the operation and control system feeds back the satellite resource monitoring condition to the task scheduling center.
