基于1553B总线的通信接口及其应用

Communication Interface Base on 1553B Bus and Its Application

论述了MIL-STD-1553B总线作为军用标准的特点及其通信接口的要求.通过通信驱动器BU-61580实现单片机与M IL-STD-1553B间通信的实例,讲述了用1553B总线通信的可行性及BU-61580作为1553B接口芯片的特点和具有的功能,并给出了通信框图和部分程序.实践证明,用1553B进行通信能将数据完整可靠地传送到总控制处.

As a military standard and the requirement on the interface of 1553B bus, the characteristic of MIL-STD-1553B were discussed. BU-61580＇s characteristics and function as an Advanced Communication Engine （ACE） were taken as an application sample to show the feasibility of 1553B bus communication and the character and functions of BU-61580 interface chip. The frame chart and part of the procedure were also given. It is proved that data can be transmitted integrally and safely by 1553B bus.
