Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] A multi-person collaborative floor positioning method, comprising the steps:

[0036] (S1) The target positioning unit and the assisting unit receive each other's wireless signals, collect signal information, and send it to the server together with the information collected by the inertial sensor;

[0037] (S2) Build a floor positioning model and obtain model data information;

[0038] (S3) Calculate the system parameters of the floor positioning algorithm, and obtain the final height value of the target positioning unit.

[0039] There are three or more auxiliary units and they are located on the same floor.

[0040] The step S1 receiving each other's wireless signals includes:

[0041] S11. The device equipped with the target positioning unit sends a positioning signal based on the carrier sense multiple access technology;

[0042] S12. The...

Abstract

The invention, which relates to the wireless information processing technology, discloses a multi-user cooperation type floor positioning method and system. The method comprises: (S1), a target positioning unit and a cooperation unit receive respective wireless signals, collect signal information, and send information including information collected by an inertial sensor to a server side; (S2), a floor positioning model is constructed and model data information is obtained; and (S3), a system parameter of a floor positioning algorithm is calculated and a final height value of the target positioning unit is obtained. The method and system have the following beneficial effects: on the basis of severe environments like a fire environment and multiple positioning workers, connection between the destination positioning staff and the auxiliary positioning staff is established and the accumulated error of the destination positioning staff is eliminated, so that the effective floor positioning function is realized and the life safety of the positioning staff can be guaranteed substantially.

Description

technical field [0001] The invention relates to wireless information processing technology, in particular to a multi-person cooperative floor positioning method and system. Background technique [0002] With the rapid development of the economy, buildings are becoming taller and larger, so indoor positioning has become a new research topic, and some results have been achieved so far. Floor positioning is a type of indoor positioning, and currently there are many technical bottlenecks. First of all, GPS cannot be used for indoor positioning; because GPS is only suitable for line-of-sight positioning, but there will be many walls blocking the building. Secondly, the traditional WiFi three-point positioning model and infrared positioning technology cannot be applied to floor positioning. In addition, most of the current research is limited to in-plane, for floor localization, it is a stereo model, so new methods are needed. In order to locate the floor where the target perso...
