基于“主—从”式实时数字量采集接口的设计

Based on M-S Architecture a Real-time Data Acquisition Interface Design

本文叙述一种实时数字量采集接口的设计，该接口插入PC机，与PC机一起构成“主—从”式结构，具有兼容性好、传送距离远、速率高及成本低的特点。

This paper describes a design of real-time data acquisition interface. Inserted in the PC, the interface Consists of a master-slave architecture, and it has the merits of good compatibility, long distance, high speed, and low cost.
