High speed data transmission system based on single-core logging cable

The utility model discloses a high speed data transmission system based on a single-core logging cable. The high speed data transmission system based on the single-core logging cable comprises a ground part and an underground part which are connected by a single-core logging cable. The ground part comprises a ground user data interface, an orthogonal frequency division multiplexing (OFDM) demodulator, an AMI encoder, and a ground analog front end. The underground part comprises an underground analog front end, an AMI decoder, an OFDM modulator, and an underground user data interface. A downlink channel of the high speed data transmission system is formed by the ground user data interface, the AMI encoder, the ground analog front end, the single-core logging cable, the underground analog front end, the AMI decoder, and the underground user data interface in a sequential connection mode. An uplink channel of the high speed data transmission system is formed by the underground user data interface, the OFDM modulator, the underground analog front end, the single-core logging cable, the ground analog front end, the OFDM modulator and the ground user data interface in a sequential connection mode. The high speed data transmission system based on the single-core logging cable is capable of achieving double-way high speed data transmission rate and meeting the site requirement of a production log on the single-core logging cable.
