Abstract
A dynamic power positioning method and a dynamic power positioning system thereof are disclosed. The method comprises the steps of: controlling a device to be measured to transmit a plurality of positioning signals with a plurality of transmission powers; making a plurality of known location devices to receive the plurality of positioning signals, and recording the intensities and the corresponding reception times of the plurality of positioning signals, and the coordinates of the plurality of known location devices to the database; finding out the known location device corresponding to a positioning signal having a higher signal intensity among the received plurality of positioning signals; obtaining a signal intensity-distance function and a signal intensity-distance standard deviation function from the database; and finding out the device location of the device to be measured according to the signal intensity-distance function and signal intensity-distance standard deviation function.
