For the convenience of understanding the present embodiment, first, the disaster recovery methods based on the task scheduling center disclosed in the embodiment of the present invention are described in detail.
Fig. 1 is a schematic flow chart of disaster recovery methods 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.

And S208, selecting a second target scheduling center which is less in the th historical task quantity according to the th historical task distribution condition, and sending the user application information to the second target task scheduling center.
If the number of tasks historically allocated to the th 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 th task scheduling center to which the historical tasks are allocated less frequently.
In order to further reduce the pressure of the applied task scheduling center, the embodiments of the present invention may also allocate according to the pressure condition (the allocation execution condition of the historical task) of the task scheduling center when the link is established and/or the management and control information is uploaded.
