The invention discloses a wireless charging system alignment method and equipment, and the method comprises the steps: S1, judging whether a positioning electromagnetic signal is received or not, if yes, entering a fine guiding step, and otherwise, entering a coarse guiding step; the step of coarse guiding comprises the following sub-steps: S21, acquiring first geomagnetic data of a position where the vehicle is located, wherein the first geomagnetic data comprises a north component, an east component and a vertical component of magnetic field intensity; S22, comparing and matching the first terrestrial magnetism data with a terrestrial magnetism database to obtain coordinates of the position where the vehicle is located; the fine guiding comprises the following steps: S31, receiving a positioning electromagnetic signal; S32, judging whether the positioning electromagnetic signal is credible or not, and if yes, entering S33: completing a guide action according to the positioning electromagnetic signal until alignment; otherwise, performing the coarse boot step at the same time until credibility is achieved. According to the wireless charging system alignment method and the wireless charging system alignment equipment, interference of the environment on guiding and positioning can be reduced, the method has a coarse guiding step and a fine guiding step, and alignment operation of wireless charging is completed reasonably and efficiently.

    本发明公开了无线充电系统对准方法和设备,方法包括:S1:判断是否接收到定位电磁信号,是则进入细引导步骤,否则进入粗引导步骤;粗引导步骤为S21:获取车辆所在处的第一地磁数据,第一地磁数据包括磁场强度北分量、东分量和垂直分量;S22:第一地磁数据与地磁数据库对比和匹配,获取车辆所在处的坐标;细引导步骤为S31:接收定位电磁信号;S32:判断定位电磁信号是否可信,是则进入S33:根据定位电磁信号完成引导动作,直至对齐;否则同时进行粗引导步骤,直至可信。本发明的无线充电系统对准方法和无线充电系统对准设备,能够减少环境对引导定位的干扰,具有粗引导步骤和细引导步骤两大部分,合理高效的完成无线充电的对准作业。
