Abstract

The invention provides a positioning guiding method, system and device. The method comprises the steps of measuring a magnetic field value of an electromagnetic signal transmitted by a transmitting end; calculating a numerical gradient of the magnetic field value based on the measured magnetic field value; and guiding equipment to adjust the position and posture according to the numerical gradient of the magnetic field value so as to align the equipment with the transmitting end. According to the application, the receiving end can search according to the gradient direction of the electromagnetic field distribution, so that accurate registration of the transmitting end and the receiving end can be realized. Besides, the receiving end realizes position calibration based on the numerical gradient of the electromagnetic signal, so that the defect that the electromagnetic signal is easily interfered by an environment (such as a metal object) can be effectively overcome, and the accuracy of guide positioning is improved.

Description

technical field [0001] The present application relates to the field of positioning, and in particular to a method, system and device for positioning guidance. Background technique [0002] Wireless charging technology has many advantages, such as safe operation, flexible and convenient, and low maintenance cost, so it has received more and more attention, and it is one of the development trends of electric vehicle power supply technology in the future. The decrease in wireless charging efficiency caused by problems such as alignment difficulties and alignment deviations in the wireless charging process is an urgent problem to be solved. Contents of the invention [0003] The present application provides a method, system and device for positioning guidance, in order to improve the accuracy of positioning guidance. [0004] In the first aspect, a positioning guidance method is provided, which can be executed by the receiving end device (or receiving end), or can also be exe...
