Abstract

The invention discloses a method and system for multi-base station positioning. The method for multi-base station positioning includes the steps: performing hierarchical division of the master and theslave on each base station in an LE positioning engine; setting an adjacent minimum calculation unit in each direction of each minimum calculation unit; calculating a first coordinate value of the minimum calculation unit for at least N times; if the difference between the second coordinate values is within a preset first threshold, acquiring an average value of coordinates corresponding to the second coordinate value; and taking the average value of the coordinates as a static coordinate value of a positioning tag, and using a map-nested data structure to quickly find the positioning tag according to a key value Key and move the positioning tag to the next minimum unit. The system for multi-base station positioning is a typical distributed system, so that the system needs precise time synchronization, and the adjacent level node time synchronization mode satisfies this requirement.

Description

Technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular, to a method and system for multi-base station positioning. Background technique [0002] In recent years, with the continuous development of short-range wireless communication and mobile network technologies, location-based services (LBS) have attracted more and more attention. The global positioning system (GPS) can already provide location information outdoors, but it cannot work normally in an indoor environment due to the occlusion of buildings and the high density of floors. In this case, indoor positioning solutions using carrier technologies such as infrared, WiFi, and Zigbee have emerged, but they have not achieved very good results. WiFi technology has high energy consumption and is susceptible to signal interference, and the signal coverage is limited to a space within 90m, so the advantages of this technology are not obvious; Zigbee techno...
