摘　　要：针对已成为现在PC工业标准的通用串行总线USB在多点数据采集中的高效、经济、便利这些特点,给出了一种基于USB技术和传统485总线采集卡相结合的远距离多点实时数据采集的实现方法,该方法集中了传统485数据采集卡和USB的优点。主要介绍了实现该方法的硬件系统结构、软件系统构成、远距离数据传输系统、多空间、工作点相对分散且每点有多个数据的综合数据传输系统。This paper introduced a method which can acquire remote multi-spot data . USB has become the standard of PC industry now,which bases on characteristicses of USB such as efficient, economical, convenient .It combines USB technology and traditional 485 Bus acquisition card. This method concentrate the advantages of USB technology and traditional 485 Bus acquisition card. It is presented the hardware system structure, the software system structure of that method, the system of remote data transmission, the synthesis data transmission system as working space is dispersing and there are multi-data in one spot.
