摘要： 在卫星数传调度研究中，待调度方案形成后，通常不做任务调整，但实际中会有应急情况出现。为解决该问题，提出一种任务调度模型。将卫星数传任务分为常管任务和应急任务，建立应急任务模型，设计其调度算法，具体包括调度顺序的确定、初始调度方案的调整以及调度流程。实验结果表明，该算法能保证应急任务的优先级之和最大，同时保持原方案的稳定性。

Abstract: In the study of satellite data transmission schedule problem, schedule tasks are not adjusted after laying out the scheme. In practical, emergent conditions often appear. To solve this problem, the model for emergency task schedule is proposed. Satellite data transmission tasks are divided into regular task and emergency task. The model for emergency task is constructed. The scheduling algorithm is designed. It contains the determination of scheduling order, the adjusting strategy for initial scheme, and the scheduling process. Experimental results show that the algorithm can maximize the sum of the emergency tasks priority, and keep the initial scheme stable.

Key words: satellite data transmission, emergency schedule, schedule priority, adjustment strategy
