| Abstract: | Based
on correlation theory,this paper presents an intelligent cross correlation flow measurement
system by using Digital Signal Processor (DSP). Different from time domain method such as
polarity correlation, the method of frequency domain is applied to correlation calculation in this
system. Feasibility and latent advantage of this method is also discussed in this paper. This
system has master slave configuration and runs under interrupt mode. The result of experiment
shows that the system has good fuction of real time processing. |
