The invention discloses a multifunctional real-time wireless monitoring demodulation system. In the system, a multi-parameter coplanar integrated resonant sensor is connected with a radio frequency signal acquisition/demodulation circuit; the radio frequency signal acquisition/demodulation circuit is connected with the upper computer; the multi-parameter coplanar integrated resonant sensor comprises a first substrate, a second substrate, a temperature sensitive unit and a pressure sensitive unit, a groove is formed in the lower surface of the first substrate; the upper surface of the second substrate and the lower surface of the first substrate are bonded together, so that a closed cavity is formed in the groove; the pressure sensitive unit is arranged on the upper surface of the first substrate corresponding to the central position of the cavity; the temperature sensitive unit is arranged on the upper surface of the first substrate and is a set distance away from the pressure sensitive unit; the temperature
