The invention belongs to the technical field of UWB positioning. The invention specifically relates to an intelligent switching method for positioning base stations required by a UWB
positioning system in two-dimensional and three-dimensional positioning scenes. The method comprises the following steps: S1, giving different positioning
base station receiving
signal angles [theta]i, j (i = 1, 2, 3,and the like, N, j = 1, 2, 3, and the like, M) to different positioning base stations according to positioning node receiving angles, N being the number of
layers where the positioning base stationsare located, and M being the number of the base stations; and S2, initially setting a two-dimensional positioning scene, and judging that the positioning tag is located between the several
layers of base stations according to positive and negative conditions of [theta]i, j values. The required positioning
base station is intelligently switched by using the positive and negative value change of thesignal receiving angle of the positioning tag and the positioning
base station, so that the link of the positioning tag, which is irrelevant to the current positioning, is reduced, the
utilization rate of the base
station is optimized, and the average
power consumption of the whole
positioning system is reduced.
