摘要
电阻层析成像 (ERT)是两相流 /多相流检测的新技术 ,其动态实时性能直接关系到能否应用于工业过程参数检测和监控 .为此分析了影响 ERT实时性能的主要原因 ,着重介绍了利用有源高通滤波方法提高实时性能的理论和实验研究结果 ,给出了影响实时性能的瞬态过程分析 .
Electrical resistance tomography(ERT) is a new technology used in two phase/multi phase flow measurement,and its real time performance directly affects its industrial applications in the measurement and monitoring of process parameters.Based on the analyses of the main factors affecting the real time performance of ERT,a method of using an active high pass filter to improve the real time performance of the system is introduced in this paper. In the meantime,the filter design,signal response analysis and experimental results are also given.
