摘　　要：在新一代先进综合航空电子系统体系结构中,采用蓝图系统来完成航电系统结构的描述;针对蓝图系统进行实时性保障研究,是对蓝图系统展开研究的一个重要方面。首先探讨了蓝图系统的结构,在此基础上分析了任务在航空电子系统中的加载和运行模式,并针对6种典型运行模型,给出了蓝图系统实时性保障的判定定理,最后通过计算机仿真验证的方式对这6种典型运行模型的可调度性进行了分析和对比。In the architecture of the modern advanced integrated avionic system,blueprint system is adopted to describe the whole avionic system.One of the most important aspects of study on blueprint system is to investigate its real-time performance.Firstly,the structure of blueprint system was discussed.On this basis,the loading and operating mode of avionic tasks in the avionic system was analyzed.After that,6 typical operating models were addressed,and the theorem for real-time performance judgment was proposed individually.Computer simulation was made to study and analyze the schedulable performance of the 6 typical models.
