摘　　要：研制了一套发电机电压波动信号分析系统,并给出了系统的总体框架。然后根据系统上下位机对传输速度和精度的要求,选择USB串行通信开发研制了系统数据传输模块,USB硬件采用飞利浦PDIUS-BD12芯片。给出了具体的通信协议和流程控制。最后通过频谱分析仪Agilent35670A、频谱分析仪Co-Co80进行了实验比较验证,达到了预期目标。An analysis system of generator voltage fluctuation signal is developed, and the general framework of the system is given. Then according to the requirements of upper computer to signal collecting apparatus about transfer speed and degree of accuracy, USB serial communication is chosen to develop system data transmission module. Selecting Philips PDIUSBD12 chip as USB hardware, the concrete communications protocol and flows control are given. Finally using frequency spectrum analyzer Agilent35670A and frequency spectrum analyzer CoCo80, the experiments is carried to verify the system precision.
