Abstract:
A wireless positioning system for detecting a positioning coordinate of a person comprises a wireless positioning device for sending a wireless broadcast signal comprising a device identity code and a motion vector; a plurality of wireless base stations for receiving the wireless broadcast signal and sending a positioning signal comprising a wireless broadcast signal and an RSSI; and a positioning server for receiving the positioning signal and calculating the positioning coordinates of the wireless positioning device according to the positioning signal. Wherein, when the received positioning signal is insufficient to calculate the positioning coordinates, the positioning coordinates are calculated based on the last positioning coordinate plus the motion vector. Compared with the prior art, the wireless positioning system of the present invention uses the RSSI to cooperate with the motion vector. The wireless positioning range is expanded with more accuracy.

Claim (Index 4):
A wireless positioning system for detecting a positioning coordinate of a person to be positioned, wherein the wireless positioning system comprises:\n a wireless positioning device, configured on the person to be positioned, comprising:\n a motion detecting module, for detecting a movement of the wireless positioning device, and calculating to generate a motion vector according to the movement; and \n a wireless transmitting module, connected to the motion detecting module, wherein the wireless transmitting module is used for sending a wireless broadcast signal comprising the motion vector and a device identity code; \n a plurality of wireless base stations, distributed in a space, wherein each of the wireless base stations communicates with the wireless positioning device to receive the wireless broadcast signal, and calculates a wireless signal strength indicator of the received wireless broadcast signal, and then sends a positioning signal comprising the wireless broadcast signal, the wireless signal strength indicator, and a location identity code of the wireless base station; and a positioning server, communicating with the wireless base stations to receive the positioning signals respectively from the wireless base stations, and generating a first positioning coordinate of the wireless positioning device according to the device identity code, the wireless signal strength indicator, and the location identity code comprised in each positioning signal, and generating a second positioning coordinate of the wireless positioning device according to the device identity code and the motion vector comprised in each positioning signal; wherein, when the error value between the first positioning coordinate and the second positioning coordinate is less than a preset value, the positioning coordinate of the wireless positioning device is generated.
