Abstract

The invention discloses a positioning method based on wireless beacon position sensing, and relates to the technical field of wireless network positioning. In order to solve the problems of RSSI distortion of a signal strength value and inaccuracy of a reference beacon for positioning due to the fact that a wireless signal is affected by the environment to generate a multipath effect, the invention provides the following technical scheme: the positioning method based on wireless beacon position sensing comprises the following steps: drawing a map of a positioning area; deploying a wireless beacon in the positioning area based on a preset deployment rule; establishing a beacon tree set based on the feature information collected by the wireless beacon and a preset beacon filtering rule; andbased on the beacon information of the beacon tree set, combining a positioning algorithm to obtain coordinates of a positioning point.

Description

technical field [0001] The invention relates to the technical field of wireless network positioning, in particular to a positioning method based on wireless beacon position awareness. Background technique [0002] Commonly used wireless signal positioning algorithms include triangulation positioning, distance weight positioning, and TDOA positioning. The above positioning algorithms need to use the signal strength value RSSI to judge the actual distance between the positioning point and the reference beacon, and then achieve the purpose of positioning. However, the wireless signals used for positioning are all electromagnetic waves, and the complex physical environment in real life leads to more and more obvious multipath effects of electromagnetic waves, such as distortion of the main signal characteristics of wireless signals and inaccurate signal strength values ​​such as RSSI. In turn, the calculation of the actual distance between the positioning point and the reference...
