FSK-Modulated Signal System for Downhole Acoustic Transmission Based on AD9838

XU Fei;DANG Bo;WANG Xin-ya;OU Shan-shan;BI Ling-zhi;Xi'an Shiyou University;  
Aiming at the problems of low data rate and high bit error rate of downhole acoustic wave transmission, an FSK-modulated signal system based on AD9838 is proposed. Firstly, the downhole temperature sensor DS18 B20 collects downhole temperature data and sends these data to the ds PIC main controller. Then, ds PIC converts these data into binary data with the decimal-to-binary algorithm and converts these binary data into an eight-bit symbol sequence with internal timer module. Finally, according to the value of the symbol sequence outside the main program, 1 or 0, different frequency control words are written into AD9838 to change the frequency of the sine wave output of the AD9838 to achieve FSK modulation. The experimental results show that this method can reduce the transmission error effectively compared with the traditional hardware modulation circuits, and has the advantages of small structure and easy to switch the modulation frequencies.
