Two-stage layering hybrid system of separation module spacecraft

Abstract

The invention discloses a two-stage layering hybrid system of a separation module spacecraft. An operation control and mission planning portion comprises a decision management layer and a behavior executing layer. The decision management layer is provided with two management modules, sends cooperation requests for a specific mission, clears a cooperation mechanism and strategies, conducts the mission planning after the cooperative relationship is determined, and generates a specific mission command. The behavior executing layer is provided with a plurality of working modules, forms the cooperative relationship with the decision management layer in a certain mode, obtains the allocated mission, conducts the mission planning under the guidance of the cooperation mechanism and generates a motion sequence so as to enable the working modules to cooperatively complete the observing mission. One management module is set to be a standby module. The two-stage layering hybrid system of the separation module spacecraft has the advantages that the system suitability is good, the system calculated amount is reasonable and balanced, the CPU bottleneck problem does not easily occur, and the system stability is good.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a two-stage hierarchical mixing system for a separate module spacecraft. Background technique [0002] Such as figure 1 As shown, the separate module spacecraft management and control system can be divided into two parts according to different business divisions, namely operation management and control and mission planning and basic services. The operation control and task planning part is mainly responsible for the daily and emergency operation management of the module group, as well as demand-oriented task planning and resource scheduling; the basic service part mainly provides data and control support for the normal work of the first part. The operation control and mission planning part of the module group can be subdivided into the ground system and the on-board autonomous system. The ground system is mainly responsible for offline demand management, preprocessing, missio...

Problems solved by technology

However, because the management is too centralized, the management module needs to continuously monitor the status of the working module, so it lacks flexibility, poor dynamic response performance, relatively high communication bandwidth, reliability and real-time performance, and there is also the CPU bottleneck problem of the management module; Centralized feedback architecture, due to the decentralization of "control", the CPU bottleneck problem of the management module is alleviated to a certain extent, the "intelligence" of the entire system is better distributed and strengthened, and the system has relatively better flexibility and adaptability. However, there is only one management module, and when the space situation is complex, the system reliability may not meet the requirements
