Space foundation measurement and control data transmission resource overall scheduling priority system design method

Abstract

The invention discloses a space foundation measurement and control data transmission resource overall scheduling priority system design method. The method is specifically implemented according to thefollowing steps that 1, aiming at a large number of subtasks of different guarantee task types, establishing a task requirement priority model, a spaceflight control priority model and an equipment use priority model respectively according to three layers of task requirements, spaceflight control and equipment use, and the priority of each layer is determined through weighted calculation of different weight indexes; 2, according to different element attributes of task requirements, aerospace control and equipment use, decomposing step by step to establish a task requirement priority evaluationindex, an aerospace control priority evaluation index and an equipment use priority evaluation index respectively; and 3, according to the evaluation indexes established in the step 2, establishing weight allocation of task demand priority indexes, weight allocation of aerospace control priority indexes and weight allocation of equipment use priority indexes. The method is oriented to overall scheduling of sky foundation measurement and control data transmission resources, and is high in universality and easy to implement.

Problems solved by technology

[0003] With the in-depth advancement of the aerospace power strategy, China's civil and commercial aerospace has shown a blowout development, with thousands of spacecraft, manned spaceflight, space exploration, combat support and remote sensing observation, communication, surveying and mapping, meteorology and other military and civilian application fields The demand for space-ground-based TT&C data transmission resource support tasks has increased sharply, and the importance of existing tasks is determined by users in various fields. The rules are simple and have not yet covered all task types. The importance of task types cannot be quantitatively evaluated as a whole. In the case of multi-users, different fields, and different types of task conflicts, the scheduling of space-ground measurement and control data transmission resources mainly adopts manual coordination. There are many information interaction links and conflict resolution is difficult. The system The timeliness of response and task satisfaction rate are difficult to guarantee and cannot meet user needs, which seriously restricts the maximum use efficiency of resources
