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.
