a predetermined distance	Preset angle
		L1	θ1
L2	θ2
		L3	θ3
...	...
		Ln	θn

In specific implementation, the greater the number of the preset calibration positions, that is, the greater n is, the more detailed the calibration position information of the preset area is, the higher the accuracy of calibrating the preset area is, but the greater n is, the longer the time required for calibrating the preset area is, and the larger the occupied storage space is, so that in the process of calibrating the preset area, the following steps may be further included:

a1, determining a first angle difference value between a preset angle of an ith preset calibration position and a preset angle of an ith-1 preset calibration position, wherein i is a positive integer greater than 1;

a2, determining a distance difference value between a preset distance of the ith preset calibration position and a preset distance of the (i-1) th preset calibration position;

Therefore, the number of the preset calibration positions can be more reasonably controlled by flexibly controlling the included angle between the adjacent preset calibration positions, so that the preset calibration positions are selected densely when being dense and sparsely when being sparse, the calibration accuracy of the preset region can be ensured, and the number of the preset calibration positions and the calibration time of the preset region can be reasonably controlled.

Matching the relative angle with a preset angle in the map calibration information list, specifically determining whether a preset distance consistent with the relative angle θ t is included in the map calibration information list, and if a preset angle consistent with the relative angle θ t is obtained, for example, θ t ═ θ 3, the relative distance L may be adjusted_tComparing the first reference preset distance L3 corresponding to the preset angle theta 3 if the relative distance L_tAnd if the first reference preset distance L3 is smaller than or equal to the first reference preset distance L3, determining that the electronic device is in the preset area of the UWB device.

Optionally, the method further comprises:

1023. if the map calibration information list does not include a preset angle consistent with the relative angle, selecting a reference preset angle closest to the relative angle in the map calibration information list;

1024. and comparing the relative distance with a second reference preset distance corresponding to the reference preset angle, and if the relative distance is smaller than or equal to the second reference preset distance, determining that the electronic equipment is in a preset area of the UWB equipment.

Considering that the number of the preset calibration positions is limited when the preset area is calibrated in advance, the preset map calibration information list may include a preset angle consistent with the relative angle or may not include a preset angle consistent with the relative angle, if the preset angle consistent with the relative angle is not included in the map calibration information list, a reference preset angle closest to the relative angle in the map calibration information list, for example, a reference preset angle θ 2 closest to the relative angle θ t, may be selected, and then the relative distance L is compared with the preset distance θ t_tComparing the second reference preset distance L2 corresponding to the reference preset angle theta 2, if the relative distance L_tIf the second reference preset distance L2 is less than or equal to the second reference preset distance L2, the electronic device is determined to be in the preset area of the UWB device。

103. If so, closing the screen locking function of the electronic equipment; if not, the screen locking function of the electronic equipment is kept.
