Abstract

The invention discloses a signal base station three-dimensional positioning system and method based on RSSI and AOA. The signal base station three-dimensional positioning system comprises an electronic tag arranged on a person to be positioned or a device to be positioned and further comprises a wireless base station capable of being arranged at a base station positioning position. Wireless communication can be conducted between the electronic tag and the wireless base station, the wireless base station is in wireless connection with a wireless gateway which is connected with a server, and the server is connected with a PDA or a PC. The signal base station three-dimensional positioning system and method based on RSSI and AOA can effectively overcome the defects that an wireless sensor network is poor in penetrability, and inconvenient to install, arrange and maintain, and effectively reduce the number of arranged base stations.

Description

technical field [0001] The invention belongs to the technical field of wireless networks, and in particular relates to a three-dimensional positioning system and a positioning method for a single base station based on RSSI and AOA. Background technique [0002] With the advancement of technology, there are more and more skyscrapers, and the demand for indoor positioning is increasing. The Global Positioning System (GPS) is widely used, but due to the shielding effect of buildings, GPS cannot be used for indoor positioning. [0003] The application number is 200910063608.8, the publication date is January 27, 2010, and the invention patent application with the publication number CN101635880A discloses a three-dimensional precise positioning method based on wireless sensor network, which uses wireless sensor network technology to detect signal strength to Calculate the distance between the base station and the tag, and use the circular positioning algorithm to obtain the thre...
