摘　　要：对基于MIL-STD-1553B多路传输数据总线先进飞机的分布式配电系统的结构和功能进行了分析,重点论述了总线监控器的功能及应用软件的设计及实现;配电系统的消息数量多而且传输频率高,因此如何实现实时监控消息是软件设计的关键;采用Windows消息驱动机制和多线程概念,并结合实时内存数据库技术,很好地解决了实时问题;总线通信试验表明,系统运行可靠,达到了功能要求,具有很好的监控效果,可用于分布式配电系统中。The construction and function of the advanced aircraft power system based on MIL-STD-1553B bus is analyzed. The func tion of the bus monitor and the design and realization of the software is presented. Because messages transferred on the bus has a large number and high frequency, the key of the design of the software is to realize the real-time monitoring function of all information. The real- time problem is well solved through the use of the message drive mechanism and multithreading concept of Windows and real-time main memory database technology. The bus communication experiment demonstrates that the system requirements of stable running and real-time communication are perfectly satisfied.
