A Bluetooth indoor positioning method based on marker nodes

Abstract

The invention discloses a Bluetooth indoor positioning method based on a mark node, wherein the method comprises the steps of 1, setting and disposing a public net server which receives mobile equipment information; 2, marking a certain number of mark nodes containing various address names, and marking address names on the shell of the mark nodes; 3, installing or embedding a communication APP into the mobile device, registering the device in the public network server, and carrying out Bluetooth matching with each mark node; 4, deploying the mark node at the places same as the address namees on the shell of the flag nodes; 5, transmitting the mark node information to the mobile device by the mark node, and transmitting the name and time of the mark node to the public network server throughthe data network by the mobile device, and searching the intuitive position of the person with the mobile device through the public network server by the relevant personnel.

Description

technical field [0001] The invention relates to a bluetooth indoor positioning method based on marker nodes, in particular to marker node positioning in places such as irregular mines, large indoor shopping malls, high-rise construction sites, general hospitals, airports, underground parking lots, and family residences. Background technique [0002] At present, there are many indoor positioning technologies, such as Wi-Fi positioning, Bluetooth positioning, RFID positioning, UWB (ultra-wideband) positioning, infrared technology, ultrasonic, etc. Anchor nodes or bridge nodes (also called base stations) use triangulation technology and differential algorithms to more accurately triangulate people and vehicles. The other is to record the signal strength of a huge amount of certain location points in advance, and determine the location ("fingerprint" positioning) by comparing the signal strength of the newly added device with the database with huge data; the purpose of these pos...

AI Technical Summary

Problems solved by technology

[0003] (1) Due to changes in the site, the deployed anchor nodes and bridge nodes will cause changes in the size and position of the triangle, resulting in changes in positioning parameters or inaccurate positioning;

[0004] (2) The deployment of anchor nodes and bridge nodes often requires professional and technical personnel to provide this set of equipment, the deployment cycle is long, and it is difficult to deploy in large quantities or in multiple places at the same time;

[0005] (3) The positioning parameters of the mobile device are related to the location and distance between the deployment of the anchor node and the bridge node (that is, the mobile device needs to know how these base stations are deployed in advance), and the parameters should be adjusted before using in different places. It is inconvenient to use, and at the same time, it is difficult to popularize and apply, and the cost is high;

[0006] (4) The mobile device side requires a complex triangulation algorithm, which has high requirements for computing resources and storage resources of the mobile device;

[0007] (5) The obtained coordinate data is not intuitive for finding a person. If the mapping definition from coordinates to actual address is defined on the mobile device, it will bring the complexity of use
