A Bluetooth beacon indoor positioning device based on 125k auxiliary

Abstract

The invention discloses a Bluetooth beacon indoor positioning device based on 125K auxiliary, which can solve the problem of lack of versatility of the traditional indoor positioning technology, large signal strength fluctuation, poor positioning accuracy and stability, blurred boundaries, large signal attenuation, and need to deploy more The base station has high implementation cost and complex structure, and it is difficult to realize the problem of supervision of people entering and leaving. Including a positioning system, a positioning device, a bluetooth badge and a circuit, the positioning system is composed of several 125K transmitters, bluetooth modules, several bluetooth base stations and background servers, several 125k transmitters are connected to the bluetooth module, the The Bluetooth module includes several Bluetooth tags, each of the 125K transmitters is connected to two of the Bluetooth tags, and every two Bluetooth tags connected to the 125K transmitter are connected to one of the Bluetooth base stations, and several of the Bluetooth tags are connected to each other. The Bluetooth base station is commonly connected to the background server.

Description

technical field [0001] The invention relates to an indoor positioning device, in particular to a Bluetooth beacon indoor positioning device based on 125K auxiliary. Background technique [0002] With the development of the Internet of Things and smart interconnection technologies, more and more services require the support of location information. Large-scale shopping malls and parking lots need indoor navigation systems, and industries such as prisons, detention centers, schools, and nursing homes generally need real-time location information of indoor personnel to realize personnel management and services. The existing positioning and area control systems are mainly based on RSSI intensity measurement, DOA, and TOA. According to different carriers, there are mainly the following six specific technical approaches for indoor positioning. [0003] RFID-based indoor positioning. Common frequency bands for RFID positioning are 2.4GHz, 900MHz, and 433MHz for indoor rough posit...
