Narrowband communication and Bluetooth fusion positioning system

Abstract

A narrowband communication and Bluetooth integrated positioning system comprises the following working steps that a first positioning beacon category broadcasts a Bluetooth signal, and the first positioning beacon category receives the Bluetooth signal, and transmits the Bluetooth signal to a background comprehensive position service engine through a LoRa network for positioning; a second positioning tag category broadcasts a Bluetooth signal, and a second positioning beacon category receives the Bluetooth signal and transmits the Bluetooth signal to the background comprehensive position service engine through the LoRa network for positioning; the second positioning tag category broadcasts Bluetooth signals, the first positioning tag category receives the signals and sends the signals to the comprehensive position service engine through LoRa, and the comprehensive position service engine calculates the position of the first positioning tag category according to the positioning result of the second positioning tag category; the first positioning beacon category broadcasts Bluetooth signals, and the second positioning beacon category receives the signals. According to the invention, the signal transmission problem of the positioning network is solved, the power consumption is low, the implementation cost is low, the network multiplexing problem of the positioning and monitoring network is solved, and the problems of active and passive positioning hybrid coexistence and advantage complementation are solved.

Description

technical field [0001] The invention relates to the field of positioning systems, in particular to a narrowband communication and bluetooth fusion positioning system. Background technique [0002] Existing technologies usually use low-power Bluetooth for indoor positioning, use 4G, WLAN or WiFi to transmit data, and usually use narrowband networks to transmit environmental monitoring or control data. [0003] However, the prior art has the following disadvantages: [0004] 1. The positioning network needs to use 4G and other means to transmit data, the scope of use is limited, power consumption is difficult to control, and there are signal blind spots; [0005] 2. The positioning network and the monitoring network are separated, and often need to be deployed separately, the cost is high, and the signal is interfered; [0006] 3. Active positioning is separated from passive positioning, and often either only supports active positioning or passive positioning, and the scope ...
