2results about How to "Solve data transmission" patented technology

The invention relates to an offshore underground high-frequency wireless communication device which comprises a transmitting unit and a receiving unit. The transmitting unit comprises a transmitting master control module, a transmitting circuit and a transmitting coil; the receiving unit comprises a receiving coil, a receiving circuit and a receiving main control module; the emission master control module controls the emission circuit to start and stop according to needs and outputs a coded modulation signal; the transmitting circuit carries out push-pull driving and resonance processing on the coded modulation signal and then loads the coded modulation signal to a transmitting coil to generate an alternating magnetic field; the receiving coil induces a signal of the alternating magnetic field and outputs an induction signal; the receiving circuit amplifies, filters and shapes the induction signal and then outputs a sampling signal; and the receiving master control module demodulates and processes the sampling signal to obtain a wireless receiving signal. The problem that data transmission between two short sections can be achieved only through traditional integrated manufacturing or mutual communication is solved, the problem that the working endurance time of an underground circuit is short under the battery power supply condition can also be solved, and reliable transmission of underground data is guaranteed.
