The invention discloses a device and method for detecting the position of a receiving end of a wireless power transmission system based on the array magnetic field acquisition coils shaped like a Chinese character of tian. The device comprises a transmitting coil, a detection coil, a signal conditioning circuit, a voltage signal sampling circuit, a pre-memory, a scanning comparison circuit and a display. The detection coil is fixed at the receiving end, an exciting current is introduced into the transmitting coil, and the position detection process is started; an induced voltage value of the detection coil is conditioned through the signal conditioning circuit, a voltage signal is sampled through the voltage signal sampling circuit, then the voltage signal is compared with an induced voltage meter pre-stored in the pre-memory, and a numerical result is displayed through the display. According to the present invention, the four large coils are used for magnetic field acquisition, the detectable range of the device is expanded, the detection precision of the device is improved, the design complexity of the device is simplified, and the detection process and the energy transfer process are independently and effectively carried out without interference.
