The invention discloses a central inflation and deflation system with bidirectional TPMS (tire pressure monitoring system) communication, which comprises a combination valve assembly, a wheel side valve control assembly and a battery pack, the combination valve assembly comprises a combination valve control ECU (electronic control unit) and a control valve group, and the combination valve ECU realizes pressure measurement, inflation and deflation functions of tires by adjusting the control valve group. Pressure waves are generated in the air pipes communicated with the tires; the wheel side valve assembly comprises a wheel side electric control valve ECU, a motor, an electric control valve and two sets of TPMS sensors, one set of TPMS sensors are used for collecting pressure wave signals, the wheel side electric control valve ECU issues an execution command to the motor after analyzing the pressure wave signals, the motor controls the electric control valve to be opened and closed, and the motor controls the electric control valve to be opened and closed. The other group of TPMS sensors are in signal connection with a wheel-side electric control valve ECU and a combination valve control ECU; and the battery pack is used for supplying power to the wheel side valve assembly. According to the central inflation and deflation system, bidirectional TPMS communication is achieved in a pressure fluctuation mode, and the service life of a TPMS battery is effectively prolonged.
