基于USB总线通信数据采集器的设计与实现

Design and Realization of Communication Data-collecting Card Based on USB

提出了一个基于USB接口芯片PDIUSBD12的智能通信数据采集器的设计与实现方法。该方法利用了USB总线的高带宽、使用方便、易扩展等优点,并采用了智能的协议识别技术,使通信数据采集器可以独立完成通信、数据采集的任务,从而将计算机从繁重的通信采集工作中解放出来,进而可大大提高计算机采集与监控系统的效率。

A design and implementation of an inteligent data-collecting card is introduced in this paper. The design is based on the USB interface chip--PDIUSBD12,and takes the advantage of USB, such as it′s high-speed, convenience and good expansibility. The data-collecting card can completely take on the task of communication and data-collection between computer and terminal units, thus the computer can be liberated from those heavy tasks of communication, and the efficiency of the computer acquisition and supervisory system can be improved greatly. It also adopts the intelligent identification technique, which enormously enhances the card's compatibility.
