摘要
本文研究开发了一种基于C8051F单片机和USB技术的便携式多通道高速数据采集系统,采用IIC接口技术进行I/O口扩展,并具有和上位机进行数据传输等特点。系统采用5.2英寸TFT实时显示各种波形画面和现场参数。系统可用于振动信号和各种电压信号的采集。
A portable multi-channel data-acquisition system based on C8051F and USB is presented.Using IIC technology for I/O expander,the system can transmit data with computer.A large screen LCD as good man-machine interface is used to display many kinds of waveform and data.The system can be used to sample vibration signals and other voltage signals.
