Aiming at the shallow geological structure and resource exploration field, this paper carries out a study of the key technology of shallow seismic exploration equipment to improve its design concept and the ability of extraction and recognition signal. The lock-in amplifier technology is used to solve the problem of data acquisition and processing of the weak signal with high resolution. The whole system uses ultra low power components so as to prolong the service life of the battery power supply system and to strengthen the anti-interference ability in the hardware and software design. The results show that in the laboratory environment, the design of the remote control of shallow seismic data acquisition system can realize the data acquisition with high resolution in the seismic exploration, and has strong anti-interference ability.
