摘　　要：测控信息流设计是卫星信息总体设计的重要组成部分,设计结果体现了卫星遥测遥控信息流向,其合理性和正确性决定了卫星资源配置以及星上仪器布局等.传统的测控信息流设计方法耗时长,效率低,操作繁杂,已经无法满足信息化研制模式以及与日俱增的任务需求.通过对卫星测控信息流设计过程的研究,设计了一种全新的基于模型的卫星测控信息流数字化设计方法,通过基于图形化等效建模来实现测控信息流数字化设计,不仅能够有效地弥补传统方法的不足,同时有利于优化测控信息流向设计.以某卫星为应用背景进行试用验证,设计工时减少了97.5%,设计正确率达到100%.该方法能够提高设计效率和质量,促进测控信息流设计流程、方法与产品的规范性,进一步提升信息流设计的自动化程度.Information flow design for telemetry and command(T&C) is one of the essential parts of satellite general information design.The information flow design for telemetry and command reflects the movement of telemetries and commands.Satellite resource distribution and on-board equipment layout are determined by the rationality and validity of design result.Nowadays,traditional T&C information flow design method cannot satisfy the requirements of digital design mode and increasing assignment demand.To solve these problems,a new model-based satellite T&C information flow digital design method is proposed by using graphic equivalent model.This method not only remedies the disadvantage of traditional design method,but also can be used in optimal design.This method has been tested by a satellite project,and test result shows that man-hour is reduced by 97.5%.At the same time,the validity reaches 100%.It is proved that the new method can increase design efficiency,enhance designing quality,and improve standardization of T&C information flow design process,method and product.Moreover,it can promote the automatization level of information flow design.
