摘　　要：研究了在1553B总线通讯实验系统远程终端(RT)仿真中矢量字的处理方法。设计了矢量字的手动单个设置、自动更新和使能RT中断更新三种处理方法。详细分析了各种方法中数据传输的执行过程。由于实验系统中能够灵活地设置矢量字,因此可以实现对采用更新机制传输消息的通讯过程的仿真。The processing method of vector words in remote terminal（RT） simulation of 1553B communication experimental system is studied in this paper.Three treatments are designed to process the vector words including manual setting,auto upgrading and enable-RT-interrupts upgrading.A detailed analysis is made on the process of data transmission in the proposed methods.The simulation of communication process that transmits messages via an upgrading mechanism was realized thanks to the proposed methods.
