A two-way signal positioning method and a two-way signal positioning system thereof are disclosed. The method includes the following steps: controlling a locating device to be measured to transmit a plurality of positioning signals of a plurality of transmission powers; causing a plurality of known locating devices to receive the plurality of positioning signals and return a plurality of response signals to the locating device to be measured; recording the strengths of the plurality of positioning signals, the strengths of the plurality of response signals, the plurality of corresponding receiving times and the coordinates of the plurality of known locating devices to a database; identifying the known locating devices corresponding to the stronger signals; and obtaining a signal strength-distance function and a signal strength-distance standard deviation function from the database so as to identify the device location of the locating device to be measured.

Two-way signal positioning method and two-way signal positioning system thereof

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.

Dynamic power positioning method and dynamic power positioning system thereof

A power positioning method and a power positioning device thereof are disclosed. The method comprises the steps of: controlling a device to be measured to transmit a plurality of positioning signals by a plurality of transmission powers; causing a plurality of known location devices to receive the plurality of positioning signals and recording the plurality of positioning signals and a plurality of corresponding receiving time to a database; finding out the known location device with a large signal intensity among the received plurality of positioning signals; taking out a signal intensity-distance function and a signal intensity-distance standard deviation function from the database; and finding out a device location of the device to be measured according to the signal intensity-distance function and the signal intensity-distance standard deviation function.
