The invention relates to a multi-antenna tire pressure detector automatic positioning device, which comprises a plurality of tire pressure detectors, a receiver and a central processing unit, the plurality of tire pressure detectors are arranged on each tire of a vehicle, each tire is provided with a tire pressure detector, each tire pressure detector is internally provided with a signal transmitting unit, and the central processing unit is connected with the receiver. The receiver comprises two antennas and a built-in receiving control unit, a first phase angle and a second phase angle are respectively formed between signals sent by each tire pressure detector and each antenna, and the receiving control unit receives each first phase angle and each second phase angle. And the phase difference of a plurality of different parameter values can be obtained through the operation of an operation unit built in the central processing unit, so that the position of each tire is judged, and finally, the information calculated by the operation unit of the receiver is received by a signal receiving unit built in the central processing unit and is displayed to finish the positioning.
本发明一种多天线胎压侦测器自动定位装置,其包括:数个胎压侦测器、接收器及中央处理器,数个胎压侦测器安装于车辆各轮胎,各轮胎上安装有胎压侦测器,又各胎压侦测器内建讯号发射单元,而接收器包含有二条天线及内建的接收控制单元,各胎压侦测器所发送的讯号与各天线之间分别形成第一相位角及第二相位角,接收控制单元接收各第一相位角及各第二相位角,并经过内部所内建的运算单元运算后可得数个不同参数值的相位差,进而判断各轮胎的位置,最后以中央处理器内建的讯号接收单元接收由接收器的运算单元所计算后的信息后予以显示完成定位。
