Tire pressure detecting module and tire pressure detecting system comrpising the same

A tire pressure detecting system comprising:

• a tire pressure detecting module detecting a phase angle of each of a plurality of wheels and a pressure or temperature of a tire, extracting a phase angle number matching the detected phase angle of the wheel among a plurality of phase angle numbers that are given by uniformly dividing the wheel, calculating a retransmission interval from the phase angle number to transmit tire information comprising the detected pressure value or temperature value at the retransmission interval several times;
• a wheel rotation detecting module detecting rotation information that is information with respect to a degree of rotation of each of the plurality of wheels;
• a tire information receiving module receiving the tire information, which is transmitted several times from the tire pressure detecting module, several times;
• and
• a control unit calculating a phase angle number from a receiving interval of the tire information to automatically assign a position of the tire pressure detecting module from the phase angle number and the rotation information transmitted from the wheel rotation detecting module.
