Establishment of wireless communication system for measuring while drilling based on BPSK demodulation algorithm
In the geological survey,to ensure the accuracy of the survey data and to be able to adjust the posture according to the drilling situation at any time are the key technical points in drilling engineering.At present,the communication technology of measuring while drill-ing at home and abroad is mainly based on pulse data transmission scheme,which has weak transmission performance and large limitations.Therefore,this study introduces the wire-less electromagnetic transmission technology of measuring while drilling to solve the drilling communication problem.Based on the BPSK(Binary Phase Shift Keying)modulation scheme,this study optimizes the communication transmission system and conducts the communication ex-periment.The results show that the BPSK scheme can improve the broadband capability of the sig-nal very well,with the transmission rate reaching 100 bit/s and the bit error rate solution being less than 0.1%,and hence can effectively solve the carrier problem.Meanwhile,the anti-interference a-bility of power frequency signal and noise signal is improved.The findings of this study are of great significance to the precise control of geological drilling platform.
