Liu Xi-en · Measurement & Control Technology · 2010
With the features of cross-dipole array acoustic logging signal,the design of control and processing circuit which is based on DSP+FPGA frame is presented.The hardware structure and the software design are demonstrated.It is emphasized that the way to achieve logging data communication interfaces and logic control modules.An algorithm which is used to detect head wave of cross-dipole acoustic logging signal is also introduced.The results of experiments show that the circuit can operate stably and reliably in high temperature and high pressure environment,and can satisfy the need of industrial production.
