三代机航电系统调度管理软件的设计探讨

Exploration of Design of Avionics Management Software for the 3rd Generation Fighter

对三代机航电系统调度管理软件设计开发进行了探讨,提出了多周期任务、任务模块化、分级调用、逐级查询执行等设计实现过程中比较适用的方法,针对多周期任务提出了对工作频率不同的功能进行有效划分,并通过调用最大公约数周期长度的方法来简化多周期任务的实现;针对任务模块化提出了串行模块和并行模块的结合使用的方法和要点;针对模块分级调用提出了自上而下的设计方法,同时对其时间消耗问题进行了讨论;针对查询执行提出了逐级查询判决分支流程标志并按标志决定功能走向的方法。

Design of avionics system OFP software for the 3rd generation fighter is discussed, and some applicable methods including multi -period task, task blocking, layered transfer, gradational execution are given in the paper. For multi -period tasks, the paper puts out a efficaciously partition method for some different frequency functions, and predigests the realization of multi - period tasks by transferring greatest common divisor of all period length; For task blocking ,it puts out a method of using serial blocks and parallel blocks; For layered transfer, it puts out a superincumbent design method and discusses the problem of time consuming withal ; For gradational execution , it gives a method of gradationally adjudging the embranchment control signs and deciding function trend, according on the control signs.
