Optionally, the positioning device 70 is configured to implement accurate positioning of the device to be charged 30 through a distance estimation method. The distance estimation method is an algorithm that uses the characteristics of the triangle to estimate the position of the object to be positioned, including triangulation and trilateral measurement. As shown in Fig. 12A, the triangulation method measures the angle of arrival of signals received at no less than two reference points, and the intersection of the two straight lines forming the angle is the estimated position. As shown in Fig. 12B, the trilateration method estimates the position of the point to be located by measuring the distance from the point to be located to at least 3 reference points. This measurement technology can use the received signal strength (RSS), the signal arrival time (Time Of Arrival, TOA), the signal arrival time difference (Time Difference Of Arrival, TDOA), and the received signal phase (Received Signal Phase, RSP). ) And other algorithms.

The following briefly introduces the above various algorithms:

(1) RSS: The attenuation of the transmitted signal strength is a function of the distance between the transmitter and receiver. According to the corresponding propagation signal path loss, the signal strength is converted into distance for positioning. At least three reference points are required to participate in the calculation. RSS-based systems usually require an adaptive mechanism to reduce the impact of multipath fading and shadow effects in indoor environments.

(2) TOA: The distance between the reference point and the point to be located is proportional to the propagation time of the signal. A system based on time of arrival requires at least 3 different measuring devices to complete two-dimensional positioning. The TOA system requires time synchronization between all transmitters and receivers. If there are multiple reference points, use the least square algorithm to reduce the positioning error.

(3) TDOA: The time difference is converted into a distance difference according to the time when the signal transmitted from the point to be located reaches multiple measuring devices to determine the relative position of the point to be located. The TDOA method requires at least three measuring devices to participate in the measurement of the distance difference, and requires the measurement devices to maintain time synchronization.

(4) RSP: Use signal wavelength fraction to express time delay to estimate distance. This method requires the transmitter to be placed in a specific location and assumes that the transmitter transmits a completely sinusoidal signal. Use the same algorithm as TOA to measure the phase value to estimate the position, or use the same algorithm as TDOA to measure the phase difference to achieve positioning.

(5) AOA: Mainly use directional antenna or array antenna to measure the angle information of the signal from the point to be located to reach the receiver to determine the position of the point to be located.
