摘　　要：结合辅助变流器半实物仿真的需求,搭建数据监测平台,实现对高速动车组辅助变流器控制器的分析研究。首先,提出了基于工控机与数据采集卡的采集架构,搭建监测台的硬件平台。根据不同开发环境的比较,确立基于VB语言的Visual Basic软件作为开发环境。其次,针对采集卡数据读取瓶颈的关键问题,给出了DMA读取的解决方案。并且通过VB调用Windows API函数,提出了双缓存显示方案,解决了显示过程中存在的问题。最后介绍了半实物仿真数据监测界面的结构和功能。Combined with the needs of auxiliary converter semi-physical simulation, build a data monitoring platform, achieve the aim of analysis and research in auxiliary converter for high-speed EMU. Firstly, propose acquisition framework basing on IPC （Industrial Personal Computer） and DAQ Card （Data Acquisition Card）, and establish hardware platform of monitoring station. According to comparison for different development environments, choose Visual Basic software basing to VB language as development environment. Secondly, aim at the key problem of reading data with DAQ Card, DMA（Direct Memory Access） reading method is provided. And by means of VB invoking Windows API function, propose double buffer display method, solve the problems in the display process. Finally, in- troduce the structure and function of the semi-physical simulation data monitoring interface.
