摘　　要：GJB289A总线具有很高的可靠性和灵活性,广泛应用于航空航天等领域。本文提出基于Aeroflex公司UT1553BCRTM协议芯片实现的GJB289A通信接口,完成了BC和RT的基本功能,支持同步通信和异步通信。文中对同步通信采用传统的静态总线控制协议,采用一种改进的静态总线控制技术,对非周期消息的异步通讯进行了详细说明。本设计有效地改善了GJB289A总线中非周期消息的传输延迟,保证了消息通讯的实时性。GJB289A bus has very high reliability and flexibility, is widely used in aerospace and other fields. This paper presents the GJB289A communication interface based on UT1553BCRTM protocol chip from Aeroflex, this interface implements the basic functions of Bus Controller and Remote Terminal, supporting to synchronous and asynchronous communication. In this paper, the traditional static bus controller protocol and an improved static bus controller technique is used for synchronous communication, and the asynchronous communication for aperiodic messages is described in detail. This design effectively improves the transmission delay of aperiodic message in the GJB289A bus, ensures the real-time communication.
