一种多通道数据采集系统设计研究

摘要

Multi-channel data acquisition system is designed and adopts the C8051F020 microcontroller. The data acquisition system uses USB interface to transfer data in communication between the system and computer, the USB interface provides power for this system. The monitor interface and some control commands are designed by employing VB6.0, collection data is saved as a binary file. The experiment and application show that this system is portable and easy to use, and achieve the design requirement.%以C8051F020单片机为核心设计了多通道数据采集系统，采集系统通过USB与计算机连接，USB实现采集系统供电以及数据通信。基于VB6．0软件设计了控制界面和控制命令，采集数据以二进制文件形式保存，实现数据的多通道便携式数据采集。实际应用表明，该系统便携、操作方便，达到了设计要求。
