Embodiment Construction

[0045] After discovering the above problems, the inventors of the present application conducted detailed research on existing indoor positioning technologies. The research found that the existing indoor environment is generally based on the base station having a Bluetooth or WIFI signal, and the positioning is also carried out under the Bluetooth or WIFI signal environment, usually including the following four methods: regional positioning method, triangulation positioning method, fingerprint positioning method and time difference (Time Difference of Arrival, TDOA) positioning method.

[0046] Among them, the regional positioning method is a relatively simple positioning algorithm, which directly selects the position of the access point (AP) with the largest received signal strength (Received Signal Strength Indicator, RSSI), and the positioning result is stored in the hotspot location database. The location of the current connection. Although the regional positioning method ...

Abstract

The invention provides an indoor positioning method and device and electronic equipment, and belongs to the technical field of positioning. The indoor positioning method comprises the following steps that: firstly, the received signal strength (RSSI) of a base station currently communicating with a user terminal needing to be positioned is acquired, data in a preprocessed RSSI data set are sorted, base station coordinates associated with the first three strength values in a sorting table are acquired, and a triangular positioning calculation area is formed by taking the base station as a point; three circles are drawn with three base stations as the circle centers and the distances corresponding to the received signal strength (RSSI) as the radiuses, each circle and the two adjacent edges of the triangle form two intersection points, the two intersection points are connected to obtain three connecting lines, the midpoints of the three connecting lines are taken, and a sub-positioning calculation area of the triangle is formed through the midpoints of the three connecting lines; and the coordinate value of the triangular center point of the sub-positioning calculation area is calculated, and a positioning result is output after processing. A region positioning method is improved through a triangular region method, and the positioning precision and stability are improved.

Description

technical field [0001] The invention belongs to the technical field of positioning, and in particular relates to an indoor positioning method and device, and electronic equipment. Background technique [0002] Global satellite navigation systems such as GPS, BDS, etc. and base station positioning technology basically meet the needs of users for location services in outdoor scenes, while indoor scenes have different conditions from outdoor scenes, such as being easily blocked by buildings and rapidly attenuating satellite navigation signals Even completely rejecting etc., therefore, outdoor positioning technology cannot meet the demand of indoor positioning. Contents of the invention [0003] In view of the above-mentioned defects or deficiencies in the prior art, the present invention aims to provide an indoor positioning method and device, and electronic equipment, which improves the regional positioning method through the triangular area method, and improves positioning ...
