Data Acquisition System Design of Spontaneous Potential Logging Instrument
Hui Du · Journal of Shenyang University · 2010
The advantages of the downhole data cellection by spontaneous potential logging instrument are analyzed.The data acquisition system of spontaneous potential logging instrument is designed by using AT89C 52 microcontroller as the control unit.The design ideas on pre-amplification,low-pass filter,analog-digital conversion and other circuit modules are introduced in detail.
