1. A wireless tire pressure monitoring system, comprising a controlling host module and a plurality of tire detection units;

  • the controlling host module including;

    a first central processing unit (CPU);

    a key unit electrically connected to the first CPU for setting a default standard value;

    a display unit electrically connected to the first CPU;

    a low-frequency wireless transmitter electrically connected to the first CPU for transmitting a low-frequency signal to the tire detection units and thereby informing the tire detection units to return current tire information; and

    a high-frequency wireless receiver electrically connected to the first CPU for receiving the tire information returned by the tire detection units and sending the received tire information to the first CPU; and

    the tire detection units being separately provided on tires of a transport vehicle, and each including;

    a second CPU;

    a tire information detecting device electrically connected to the second CPU for detecting tire information;

    a low-frequency wireless receiver electrically connected to the second CPU for receiving the low-frequency signal transmitted from the low-frequency wireless transmitter of the controlling host module; and

    a high-frequency wireless transmitter electrically connected to the second CPU for transmitting a high-frequency signal to transmit the tire information detected by the tire information detecting device to the high-frequency wireless receiver of the controlling host module.
