摘　　要：针对实际应用的需要 ,设计了一种基于工业控制机 ISA总线的数据传输系统。文中着重介绍了工业控制机 ISA总线及其与高速数据采集卡的接口技术。提出了一种解决慢速外设和高速系统机之间存在的时序问题的办法 ,无须插入等待周期。该系统应用于某高速数据采集系统 ,可靠性高 。To meet the need of application, this paper design a data transfer system based on the ISA bus of industrial computer. The interface between ISA bus and high-speed data sampling card is the emphasis of this paper. In addition, a method is presented to resolve the time sequence conflict between high-speed CPU and low-speed peripherals. This system has been used in a high-speed data sampling system, and with high reliability. Data can also be sampled and transferred correctly.
