The invention relates to a data transmission method which is applicable to a receiver and a plurality of transmitters. The method comprises the following steps: the transmitters sequentially and respectively transmit data to the receiver in a transmission sequence according to the different first transmission time; the different first transmission time is added to different accumulated values forrespectively becoming the different second transmission time; the different accumulated values are multiplied with the different first transmission time; and the transmitters finally transmit the next data to the receiver in the next transmission sequence according to the different second transmission time. The invention can effectively improve the problem of data collision caused by the overlap transmission time in a traditional TPMS system, and further the receiver can effectively and integrally receive all data.
