基于微机的自动转报系统的设计与实现

本文介绍了一个基于16位微型机的自动转报系统——BJC系统的设计与实现.首先,提出利用多个通用微机来组成自动转报专用系统,在开放式的操作系统上能够简单而有效地开发应用软件的方法.其次,介绍了系统的硬件组织及实现技术和分布式应用软件系统的设计思想.本文还重点描述了高效通讯软件,在线诊断程序的实现及如何实现双机动态冗余.最后对在实时环境中,如何组织应用软件作了论述.

DESIGN OF A MICROCOMPUTER BASED AUTOMATIC TELEGRAM SWITCHING SYSTEM AND ITS IMPLEMENTATION

This paper describes the implementation of the BJC 01,a 16-bit miero- computer based 128/256 line automatic telegram switching system.The paper provides the methods of using general purpose microcomputer to construct a telegram switching system and using an open-ended operating system to deve- lop application softwares efficiently.Then,it describes the hardware organiza- tion,implementation skills and the design idea of a distributed application software system.It depicts the implementation of highly efficient communica- tion programs and on-line diagnostic programs as well as the method to im- plement dynamic reundancy of duplex system to some detail.Last it discusses how to organize application softwares in a real-time enviroment.
