基于分层模型的1553B总线通用软件模块的设计及实现

Design and Realization of 1553B Bus Universal Module Based on Layered Model

1553B总线是一种数字式时分制指令响应型多路传输数据总线,对该总线的应用已有十多年时间,由于缺少1553B总线通信软件方面的设计规范,又由于1553B总线接口芯片和通信协议的复杂性,导致了软件设计的千差万别,而某些不当用法有可能带来可靠性问题或隐患;因此基于分层设计的思想对1553B总线软件通用化模块设计进行了研究,提出了总线灵活配置与资源优化利用的解决办法,并且最后通过对应用实例的验证数据进行分析来说明此设计方案的可行性。

1553B bus is a Digital time division command/response multiplex data bus which has been in application for more than a decade.However,because there is no design regulation regarding 1553B bus communication software,and also because of the complexity of the communication agreements of 1553B bus interface chips,the designs of software can be remarkably different.Some improper application way even causes proplems in reliability or invisible danger.Therefore,the thesis studies the design of 1553B bus universal module,and provides ways for flexible bus distribution and optimization of resources.The last part of the thesis proves the feasibility of the design by analyzing the verified data of real application.
