Positioning method and device

Abstract

The embodiment of the invention relates to the technical field of communications, in particular to a positioning method and device, which are used for implementing indoor positioning of persons. In the embodiment of the invention, according to received K signal intensity information of a to-be-positioned terminal and position information of K access points corresponding to the K signal intensity information of the to-be-positioned terminal, initial position information, corresponding to a first time, of the to-be-positioned terminal is determined, thereby realizing a purpose of positioning an indoor person; furthermore, according to identification of the to-be-positioned terminal, position information of the to-be-positioned terminal at a time before N moments of the first time is obtained, and the initial position information of the to-be-positioned terminal at the first time and the position information of the to-be-positioned terminal at the time before the N moments of the first time are subjected to weighting summation, thereby obtaining position information of the to-be-positioned terminal at the first time; therefore, the initial position information of the to-be-positioned terminal at the first time is optimized, and the accuracy of positioning the indoor person is further improved.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a positioning method and device. Background technique [0002] In recent years, due to the increasing scale of indoor buildings, more mobile workers are required to maintain indoor order and maintain equipment. When there are many mobile workers, there will often be phenomena such as staff shifting posts or not working at their posts during work, which will cause a lot of inconvenience to the work. Therefore, it is particularly important to locate and track personnel. [0003] The positioning system in the prior art is the Global Positioning System (Global Positioning System, referred to as: GPS) system, but the GPS system is an outdoor positioning system; when the GPS positioning receiving device is in an indoor environment, due to the obstruction of the roof, the signal strength will be greatly reduced. Attenuation, the positioning accuracy is greatly r...

When there are many mobile workers, there are often phenomena such as staff crossing posts or not working at work during work, which causes a lot of inconvenience to work, so it is particularly important to locate and track personnel

[0003] The positioning system in the prior art is the Global Positioning System (Global Positioning System, referred to as: GPS) system, but the GPS system is an outdoor positioning system; when the GPS positioning receiving device is in an indoor environment, due to the obstruction of the roof, the signal strength will be greatly reduced. Attenuation, the positioning accuracy is greatly reduced, and even the positioning cannot be completed at all
