Abstract
Official abstract text for this publication.
A positioning method adapted for a signal transmitting device and a server is provided. The positioning method includes: transmitting a reference signal by using the signal transmitting device having a low power mode and a high power mode; receiving the reference signal and determining a position of the signal transmitting device according to the reference signal and a signal strength and distance curve diagram by the server; and configuring the signal transmitting device to switch to one of the low power mode or the high power mode by the server.
First claim
Opening claim text (preview).
What is claimed is: 1. A positioning system, comprising: a signal transmitting device, having a low power mode and a high power mode and transmitting a reference signal; a transceiver, receiving the reference signal; and a server, coupled to the transceiver and storing a signal strength and distance curve diagram, wherein the signal strength and distance curve diagram comprises a first curve corresponding to the low power mode and a second curve corresponding to the high power mode, wherein the server determines a position of the signal transmitting device according to a signal strength of the reference signal and the first curve in the low power mode, and configures the signal transmitting device to switch to the high power mode according to the signal strength of the reference signal and a low power threshold through the transceiver, and wherein the server determines the position of the signal transmitting device according to the signal strength of the reference signal and the second curve in the high power mode, and configures the signal transmitting device to switch to the low power mode according to the signal strength of the reference signal and a high power threshold through the transceiver. 2. The positioning system according to claim 1 , wherein the signal transmitting device transmits an initial reference signal in the low power mode. 3. The positioning system according to claim 1 , wherein the signal transmitting device cyclically transmits the reference signal, and the transceiver cyclically receives the reference signal. 4. The positioning system according to claim 1 , wherein the server is further configured to perform: switching the signal transmitting device to the high power mode according to the signal strength of the reference signal being lower than the low power threshold; and switching the signal transmitting device to the low power mode according to the signal strength of the reference signal being higher than the high power threshold. 5. A positioning method, adapted for a signal transmitting device and a server, the positioning method comprising: transmitting a reference signal by using the signal transmitting device having a low power mode and a high power mode; receiving the reference signal by the server, and determining a position of the signal transmitting device according to the reference signal and a signal strength and distance curve diagram, wherein the signal strength and distance curve diagram comprises a first curve corresponding to the low power mode and a second curve corresponding to the high power mode; and configuring, by the server, the signal transmitting device to switch to one of the low power mode and the high power mode according to the position of the signal transmitting device, wherein the server determines the position of the signal transmitting device according to a signal strength of the reference signal and the first curve in the low power mode, and configures the signal transmitting device to switch to the high power mode according to the signal strength of the reference signal and a low power threshold through the transceiver, and wherein the server determines the position of the signal transmitting device according to the signal strength and the second curve in the high power mode, and configures the signal transmitting device to switch to the low power mode according to the signal strength and a high power threshold through the transceiver. 6. The positioning method according to claim 5 , wherein the signal transmitting device transmits an initial reference signal in the low power mode. 7. The positioning method according to claim 5 , further comprising: receiving the reference signal cyclically by the server, wherein the signal transmitting device cyclically transmits the reference signal. 8. The positioning method according to claim 5 , wherein the step of configuring, by the server, the signal transmitting device to switch to one of the low power mode and the high power mode according to the position comprises: switching the signal transmitting device to the high power mode according to the signal strength of the reference signal being lower than the low power threshold; and switching the signal transmitting device to the low power mode according to the signal strength of the reference signal being higher than the high power threshold.
