Abstract

The invention discloses an indoor positioning method and device, and a storage medium. The method comprises steps of determining a plurality of reference base stations among base stations according tosignal strength of mobile nodes and each base station and a position relationship of base stations; according to positions of reference base stations, performing rotation TDOA positioning on the mobile nodes, and acquiring initial position estimation values of a plurality of mobile nodes; determining a position of a maximum offset value corresponding to initial position estimation values in a storage space, wherein the storage space is a position storage matrix corresponding to the initial position estimation values; according to signal strength of the mobile nodes and the reference base station and the position of the maximum offset value in the storage space, calculating a correcting coefficient corresponding to each initial position estimation value; and according to the initial position estimation value and the correcting coefficient, calculating a final position of the mobile node. The method effectively overcomes fuzzy positioning of TDOA positioning algorithm and improves positioning accuracy.

Description

technical field [0001] The invention relates to the field of wireless sensor network positioning, in particular to an indoor positioning method, equipment and storage medium. Background technique [0002] The wireless sensor network is composed of a large number of micro sensor nodes deployed in the monitoring area, and is a multi-hop self-organizing network system formed by wireless communication. It senses, collects and processes the information (such as light, sound, heat, electricity, mechanics, chemistry, location, etc.) of the perceived objects in the network crazy love area, and combines with the Internet to form a huge network. Exploration, smart home, industrial control and other fields have broad application prospects. [0003] The positioning technology is an important supporting technology of the wireless sensor network. According to whether distance measurement is performed during positioning, the wireless positioning technology can be divided into ranging-base...
