摘要
设计了一种新型的基于USB接口和光纤数据传输的数据采集处理系统。系统包括:单片机控制电路;USB接口电路;光纤通信接口电路;远端模拟子机电路。该系统采用USB接口芯片,由单片机提供USB协议的上层处理,提高了传统的以单片机为基础的数据采集系统与PC机之间的数据传输速度;同时采用光纤作为远程数据传送介质,提高了系统的抗电磁干扰能力,传输距离远、速度快。系统集数据采集、传输、处理、显示和控制等功能于一体,具有良好的应用前景。
Focuses on the hardware and software of the Data Collecting and Processing System which based on the USB interface and Fiber Data Translations, The main points are as followed： USB interface technology, MCU data collecting, Fiber data translation. The system adopts USB interface chip. Microprogrammed Control Unit（MCU） provides superstratum management of USB protocol. At the same time, the system adopts Fiber as transmissive medium of long-distance data. The system has application foreground.
