Embodiment Construction

[0051] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0052] In one embodiment, such as figure 1 As shown, a space station logistics replenishment planning method for on-orbit demand traction is provided, including the following steps:

[0053] Step 100, obtaining the on-orbit event execution plan and the space station initial inventory; and obtaining the daily material consumption list according to the on-orbit event execution plan.

[0054] An on-orbit event is a non-routine task performed by astronauts in orbit, such as space science experiments and observations.

[0055] Daily material consumption includes: daily discre...

Abstract

The invention relates to a space station logistics supply planning method for on-orbit demand traction. The method comprises the steps of obtaining an on-orbit event execution plan, and obtaining a daily material consumption list according to the on-orbit event execution plan; according to the space station orbit dynamics model, calculating the occurrence time of orbit maintenance maneuver in the planning period and the consumption amount of a propellant for orbit maintenance; according to the on-orbit material demand, the preset space station on-orbit initial inventory, the preset space station on-orbit inventory capacity upper limit and the preset space station on-orbit inventory minimum warning value, determining the earliest supply time, the latest supply time and the cargo list of each cargo ship; and according to the earliest supply time and the latest supply time of each cargo ship, determining a cargo ship launching scheme by combining actual launching window constraints. The space station logistics supply planning method takes the on-orbit demand as the basis of material supply planning, quickly obtains the space station logistics supply planning scheme at a small calculation cost in a very short time, and has the advantages of high calculation efficiency, strong scheme pertinence, capability of simultaneously meeting multiple constraints, good practical engineering applicability and the like.

Description

technical field [0001] The present application relates to the technical field of space mission planning, in particular to a logistics replenishment planning method for a space station driven by on-orbit demand. Background technique [0002] The space station is a kind of comprehensive manned spacecraft that can operate in low-Earth orbit for a long time, and supports several astronauts to visit and stay, and conduct space observation and microgravity environment experiments. Space station operation mission planning is a key technology for the long-term operation and effective management of the space station. Regular visits by cargo ships for supplies are the basis for supporting the long-term operation and stability of the space station and ensuring the work and life of astronauts in orbit. Logistics supply planning is a typical problem in space station operation mission planning, and its purpose is to design cargo ship launch sequence and material loading scheme. [0003]...
