数控测井系统的总线仿真技术

Bus Simulation for Computerized Logging System

现有的各种数控系统中存在多种总线 ,总线仿真就是实现两种不兼容总线之间的相互转化 ,为用高性能的微机取代低性能的计算机奠定基础。提出了总线仿真的概念 ,介绍了 3 70 0数控测井系统的多路总线和笔者设计制作的实现 ISA总线与多路总线之间相互转化的总线仿真卡的硬件和相应的驱动软件 ,指出了总线仿真技术的广泛应用领域。

There are many kinds of buses in a systems controlled by computers in stock Bus simulation can realize transform of two incompatible buses and lay a basis to replace a low performance computer with a high performance computer A concept of bus simulation is proposed and a multiple bus for the 3700 computerized logging system is introduced Hardware and software for bus simulation card developed by authors is presented, which realizes transform of the multiple bus of 3700 and ISA bus Also,it is pointed out that bus simulation is applied widely
