description The utility model discloses a half-duplex self-adaptive communication system based on a single-core cable, which is characterized in that a ground control system is respectively connected with a plurality of underground instruments through single-core armored cables, and is used for adaptively adjusting power supply voltage to supply power to the underground instruments, and transmitting signals to the underground instruments after waveform transformation, filtering and amplification; the single-core armored cable is used for loading a signal on the single-core armored cable in a capacitive coupling manner and transmitting the signal to an underground instrument, and is also used for converting a return code signal transmitted by the underground instrument into a TTL pulse signal, analyzing the pulse signal and converting the pulse signal into a corresponding return code instruction to finish instruction confirmation; and the underground instrument is used for executing operation corresponding to the signal a
