The invention discloses a device and method for detecting the position of a receiving end of a wireless power transmission system based on a delta-shaped array type magnetic field acquisition coil. A detection coil is fixed at the receiving end, an excitation current is introduced into a transmitting coil, and a position detection process is started; an induced voltage value of the detection coil is conditioned through a signal conditioning circuit, a voltage signal sampling circuit is used for sampling a voltage signal, and a calculation circuit is used for calculating the detection sensitivity according to the sampled voltage; the calculation result is compared with an induced voltage meter pre-stored in a pre-memory, and a display is used for displaying a numerical value result. According to the present invention, the three delta-shaped large coils are used for magnetic field collection, the detectable range of the device is enlarged, 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.

    本发明公开了一种基于品字形阵列式磁场采集线圈的无线电能传输系统接收端位置检测装置及方法,所述检测线圈固定在接收端处,发射线圈中通入励磁电流,位置检测过程开启,检测线圈的感应电压值通过信号调理电路进行调理,通过电压信号采样电路对电压信号进行采样,通过计算电路根据采样电压进行检测灵敏度计算,将计算结果再与预存器中预存的感应电压数表做比对,通过显示器显示数值结果。本发明使用三个品字形排列的大线圈进行磁场采集,扩大了装置的能检范围,提升了装置的检测精度、简化了装置的设计复杂度,实现了检测过程与能量传递过程互不干扰、独立有效地进行。
