Information scheduling method and scheduling device for bus information chain

The invention relates to the technical field of spaceflight information scheduling, in particular to an information scheduling method and scheduling device for a bus information chain, and the method comprises the steps: obtaining the attribute of each bus node; associating the corresponding bus nodes based on the attribute and information of each bus node to form an information interaction link; carding the bus information, and forming key data instruction information and non-key data instruction information; the key data instruction information and the non-key data instruction information are transmitted along the corresponding information interaction links; and in the transmission process of the key data instruction information and the non-key data instruction information, each information interaction link needs to judge whether the transmission of the bus message of the previous control period is completed, if not, the bus message transmission of the current period is completed, then the bus message trans
