The invention provides an airplane tire pressure signal detection circuit. The airplane tire pressure signal detection circuit comprises a tire pressure sensor power supply circuit, a tire pressure signal sending circuit and a tire pressure signal extraction circuit, the tire pressure sensor power supply circuit is inductively coupled with a secondary side LC resonance module of the tire pressure signal sending circuit and the tire pressure signal sending circuit through a primary side LC resonance module, wireless electric energy is transmitted to the secondary side LC resonance module through the primary side LC resonance module, and a secondary side compensation capacitor is arranged in the secondary side LC resonance module. The secondary side LC resonance module is controlled to send a target tire pressure signal to the primary side LC resonance module through the capacitance state of the secondary side compensation capacitor; the input end of the tire pressure signal extraction circuit is electrically connected with the primary side LC resonance module so as to extract a target tire pressure signal received by the primary side LC resonance module. The secondary side capacitor is adopted for compensation modulation, so that the electric energy transmission efficiency is improved, the induction range of the stator and the rotor is increased, and the reliability of return signals is ensured.
