Abstract

The invention provides a method and a device for planning tasks in a space information network and relates to the technical field of satellite detection. The method comprises the following steps of obtaining a set of detection satellites and a detection task set of the detection satellites; obtaining a plurality of variables, wherein the variables are used for determining a resource allocation way of the detection satellites, and the resource allocation way includes an allocation way of detection resources and / or an allocation way of defense resources; constructing a target function based on the set of the detection satellites, the detection task set and the variables, and constructing constraints of the target function; and carrying out optimal solution on the target function based on the constraints in order to determine an optimal resource allocation way of the detection satellites according to an optimal solution result. According to the method and the device, a technical problem of poor detection gain caused by unreasonable allocation in a task allocation process in the existing technology is alleviated.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a task planning method and device in a space information network. Background technique [0002] Earth observation is one of the most important application scenarios of spatial information network. The dynamic nature of the network topology of the ground exploration satellites leads to detection only when the satellite and the detection target are visible, and the satellite observing the detection target cannot directly establish a connection with the ground station. When the satellite enters the ground station’s Data downloading is only possible within the communication range. Therefore, the observation of targets by earth observation satellites is a resource mapping problem based on time and space constraints, that is, it is necessary to allocate limited satellite or on-board sensor resources to different mission time periods, so efficient satellite mission plan...
