The physical interface , communication procedure and working model used by nrdp were also introduced . with respect to the nakp , the data unit , state - changing procedure , the service classification as well as the implementation for nakp were offered 对于位于a层与k层之间的nakp ,分析了nakp与k层主控模块的接口,以及基于其上的nakp状态变迁。
The outmost layer ( c - layer - communication layer ) deals with i / o issues between the ums and outside communication world ; the inner most layer ( k - layer , kernel layer ) involves internal management and message storage ; while the middle layer ( a - layer - auxiliary layer ) plays the go - between function between layers c and k . as the core component in layer k , the ums mail server is responsible for the storage , transmission and management of the system driven by the layer - k state machine 文中设计的zhx - ums是一个三层系统,最外层( c层?通信层)处理ums和外部通信世界的i o问题;最内层( k层?核心层)负责内部的消息管理和消息存储;中间层( a层?辅助层)处理c层与k层之间的通信及消息格式转换。 ums邮件服务器是系统三层体系结构中k层的核心模块,在k层协议机驱动下完成存储、转发及管理等任务。
The paper introduces the concept of fail - safe , the hardware and software ' s frame , divides the faults into some classes , and lists some general faults . i introduce the principle of reliability , fault forecast and it ' s standards firstly . secondly , i analyze the fmea / ca , fault tree , event tree and markov models in detail , deepen its theory and describe the flows of these models 文章介绍了故障-安全的概念、 hj04a系统的硬件和软件结构,对系统故障进行了分类,并列出了一些常见的故障;结合可靠性理论、故障预测的概念和标准,详细分析了fmea ca 、故障树、事件树、 markov故障模型,对这些理论进行了一定的深化,描述了每个故障模型的故障处理流程,并对其进行了评价;介绍了故障诊断的概念,分析了故障诊断专家系统和k层bp神经网络,提出了一种层次结构图论法的故障诊断方法。
