【摘要】 由于MIL-STD-1553B总线良好的通讯性能,在现代航空通讯系统中,MIL-STD-1553B总线正发挥着十分重要的作用。文中以DDC公司的BU-61580芯片作为MIL-STD-1553B总线接口的核心控制器,针对航空动力控制系统,介绍其硬件接口电路设计要点,以及实现1553B总线远程终端和总线控制器的软件设计方法,利用航空动力控制系统的双通道特点,实现了对1553B总线通讯的自检测功能。更多还原

【Abstract】 In the modern communication system of aviation,MIL-STD-1553B bus is playing more important role because it has good performance of communication. In this paper,the BU61580 is the core controller of MIL-STD-1553B bus interface of Aviation motor control system. The main hardware designing method is introduced,and the software designing method of implementing MIL-STD-1553B bus remote terminal and bus controller is also presented. The build-in-test function of MIL-STD-1553B bus is implemented for the dual channel’s characteristic of aviation motor control system.更多还原
