The Design of Microcomputer-Base Automatic Telegram Switching System and Its Implementation

摘要

This paper describes the imolementation of 128/256 line automatic telegram switching system-BdC01. At first we represent the hardware organization of the system. Then, we provide the methods of using general purpose 16-bit microcomouter to construct a real-time system and using an open-ended operating system to develop application software efficiently. Further more,we discuss the implementation skills and destgn ideas of a distributed Software system. We also depict the implementation of hlgh efficient communication programs and on-line dlagnose programs as well as the methods to implement dynamic redundancy of duplex system to some details. At last, we give some notes on organization of appl ication software in a real-time environment.
