磁流体发电计算机数据采集系统的研究

RESEARCH ON COMPUTERIZED DATA ACQUISITION SYSTEM FOR MHD POWER GENERATION

本文研究一套新型的应用于燃煤磁流体发电研究的计算机数据采集系统。该系统具有较高的采样频率，并且有效地改进了以往采集系统同时性不好的问题，为磁流体发电研究的进一步深入创造了良好的条件。在分析系统软硬件设计的同时，着重介绍同时性改善的实现，以及这种改善给系统带来的影响。

This study is mainly focused on the development of a new computerized data acquisition system for the coal fired MHD electrical power generation experiments.This data acquisition system has a higher speed,and it effectively resolved the nonsimultaneous problem in measurement with the old computerized data acquisition system.The successful development of this improved system can set up the excellent base for the further research and development of the Coal fired MHD electrical power generation.This paper will analyze the hardware and software design of the system.At the same time,it will introduce the way that improved the simultaneous performance and what effect had this improvement done.
