摘要
MIL-STD-1553B多路数据传输总线仿真系统是航空航天电子设备研制过程中必不可少的系统开发工具,但该总线仿真系统的实时性和可靠性也给传统的仿真技术提出了挑战。为了解决上述问题,利用LabVIEW开发工具,采用QCP-1553板卡和BU65170芯片设计了一种1553B总线通讯系统。在LabVIEW中基于UML建立模型,结合Windows消息循环机制和板卡实时中断机制,对总线控制器控制远程终端的接收和发送信息进行仿真。通过在某型号武器火控系统地检验设备上的应用,证明了上述设计方法实时性强,可靠性高,可扩展性良好。
MIL-STD-1553B is the essential system development tool,whose real-time and reliability present challenges for simulation technique.In order to solve the problems above,the 1553B communication system is designed by QCP-1553 board and BU65170 chip in LabVIEW.Combined with the message cycling and real-time interrupt mechanism,the model is built based on UML.The process of remote terminal receiving and sending information are emulated.Through the application on the weapon control system,the design method shows strong practicability,high reliability and good scalability.
