Abstract:

Previous control method of seismic exploration transponders cannot effectively reduce the interference of noise on the integrated audio of the transponder, which results in the existence of noise and affects the sound quality and effectiveness of the transponder. Therefore, a control method for the integrated audio source level of seismic exploration transponders controlled by a single-chip microcomputer is proposed. A seismic exploration transponder based on a single-chip microcomputer is constructed, which includes a power supply module, main control module, power amplifier module, matching module, receiving module, receiving/transmitting module, and receiving/transmitting transducer. The single-chip microcomputer is used to determine the working condition of the internal output, and the audio source level is identified on the basis of the optimization method of the integrated audio source layout. Results show that the proposed method can effectively enhance the integrated audio source level of the seismic exploration transponder controlled by the single-chip microcomputer. Moreover, the proposed method has a good denoising effect. The transponder controlled by the proposed method can provide better exploration results and improve the equipment for seismic exploration.
