And a receiver that receives frames transmitted from transmitters attached to each of the plurality of wheels, and transmits frames at different transmission intervals from the transmitters three or more times when the rotation angle of the wheels becomes a specific angle. When a receiver receives a frame a plurality of times, the receiver determines the number of times of transmission of the received frame from a pre-stored correspondence between a transmission order of the frame and a transmission interval, and derives a specific time within a predetermined time from detection of a specific angle from the determined transmission order of the frame. The receiver specifies which of the plurality of wheels the transmitters are mounted on, on the basis of the rotation angle of the wheel obtained by the rotation angle detection unit at the specified time.
接收机,接收从安装于多个车轮各自的发送机发送的帧且在车轮的旋转角度成为特定角度时从发送机以不同的发送间隔发送三次以上的帧。接收机在多次接收到帧时,从预先存储的帧的发送顺序与发送间隔的对应关系,判断接收到的帧为第几次发送的帧,从所判断的帧的发送顺序,导出从特定角度的检测起规定时间内的特定时刻。接收机根据通过旋转角度检测部在特定时刻得到的车轮的旋转角度,对发送机各自安装于多个车轮中的哪个车轮进行特定。
