Problems solved by technology

However, the actual application often involves the precise positioning of multiple large areas. However, the current application of UWB technology in the market is limited to the precise positioning of a small area, which is difficult to meet the practical application.

Abstract

The invention discloses a method and apparatus for multi-base station positioning. The method for multi-base station positioning includes the steps: setting an adjacent minimum calculation unit in each direction of each minimum calculation unit; after a first coordinate value is stabilized, acquiring the current minimum calculation unit by traversing according to the first coordinate value and a geometric ray method; calculating a second coordinate value of the current minimum calculation unit for at least M times, and 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 effect of positioning of multiple base stations in a large range is relatively poor in practical applications. In practice, a base station grouping tracking large-range positioning algorithm is explored, which can effectively improve defects of low large-range positioning accuracy and inaccurate positioning, thereby achieving a wide range of accurate positioning effect.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of communications, and in particular to a method and device for multi-base station positioning. Background technique [0002] In recent years, with the continuous development of short-range wireless communication and mobile network technology, location-based service (location-based service, LBS) has 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 features such as building occlusion and high floor density. In this case, there have been indoor positioning solutions using carrier technologies such as infrared, WiFi, and Zigbee, but none of them have achieved very good results. Because WiFi technology consumes a lot of energy and is susceptible to signal interference, the signal coverage is limited to a space within 90m, so the advantages of this technology ...
