摘要
针对空间站电源系统内部多个单机与其他系统进行多总线通信,实现系统内外之间数据交换的复杂信息管理需求,同时考虑到软件的可靠性和继承性,设计采用架构重构和代码重构的空间站电源系统信息管理软件,具有多任务处理实时性高的特征,能实现传统电源下位机软件代码复用,提高代码复用率。另外,通过设计基于多级静态优先级的任务调度模块,实现多总线数据流的合理通信和多任务的有效处理。文章提出的软件重构方案在空间站电源系统信息管理软件中进行应用,实现了38.47%的软件代码复用率,实时性任务的响应率提高了44.48%,可有效满足空间站电源系统的信息管理任务需求。
According to the complex information management requirement of data exchange between the internal and external of the system for the multi-bus communications between single computer and other systems in the power system of space station,also the reliability and inheritance of the software,an information management software of space station power system is designed by using architecture and code reconstruction,which is characterized by high real-time multi-task processing,the improved code reuse rate and the improved inherited reliability.Besides,the reasonable communications of multi-bus data flow and the effective processing of multi-task are realized through the design of task scheduling processing mode based on multi-level static priority.The software reconstruction scheme proposed in this paper is applied to the information management software of the space station power system.The software code reuse rate reaches 38.47%,and the real-time mission response rate increases 44.48%,which effectively meets the information management task demand of the space station power system.
