摘　　要：基于电机拖动的液压动力系统是反映液压设备运行状态的信息源,其三相电参量能全面反映设备的运行状态,为利用信息融合方法从三相电参量中获取特征信息,必须同步获取三相电流和电压信号;本文设计了基于16位同步采样A/D转换芯片AD73360和TMS320F206的三相电流和电压信号采集系统,解决了三相电参量同步获取问题,其数据精度高,实时性好,为研究和开发电机拖动设备的状态监测及故障诊断系统提供了硬件支持。Hydraulic power system based on motor drive is the message source of hydraulic equipment＇s running condition, whose three phase electricity parameters can fully reflect the running condition of devices. For the purpose of using information fusion method to get characteristic information from three phase electricity parameters, three phase voltage and current signals must be got synchronously. This paper designs a three phase current and voltage data acquisition system based on 16 bit A/D conversion chip AD73360 and TMS320F206,which solves the three phase electricity parameter synchronization getting issue, accesses high accuracy and good real-time, and provides hardware support for the research and development of motor equipment condition monitoring and fault diagnosis system.
