UWB-based prisoner positioning and alarming system

Abstract

The invention relates to the application of an indoor positioning technology, in particular to a UWB-based prisoner positioning and alarming system, which can realize the real-time positioning of prisoners and managers, the real-time check of prison conditions and the early warning of abnormal behaviors in advance through the interaction of the UWB positioning technology and an existing monitoring system. The intelligent prisoner management system comprises a position information acquisition module, a UWB (Ultra Wideband)-based prison positioning system, a prisoner management module, a prisoner management module, a prisoner management module, a prisoner management module, a prisoner management module, a prisoner management module, a prisoner management module, a prisoner management module, a prisoner management module and a prisoner management module, the position resolving module is used for filtering the original data of the position information acquisition module, resolving the position information through a positioning algorithm to obtain TDOA positioning data, and resolving to obtain two-dimensional coordinate positioning data; the positioning judgment module is used for calculating the Loc positioning data of the resolving module through an algorithm to obtain a positioning error; and the alarm judgment module formulates an alarm rule and realizes abnormal point alarm through an algorithm.

Description

technical field [0001] The invention relates to the application of indoor positioning technology, in particular to a UWB-based prisoner positioning and alarm system. Background technique [0002] With the increasing application of the Internet of Things, smart cities, disaster relief and anti-epidemic and its precise service applications, the location-based information service industry has developed rapidly and has attracted more and more people's attention and attention. Global Positioning System (GPS) and Beidou Positioning System (Beidou) cover and provide outdoor positioning information services, but due to occlusion and other reasons, they cannot be effectively applied to indoor environments. Many indoor positioning solutions have been proposed in the industry. Among them, the indoor positioning technology based on UWB has the advantages of high positioning accuracy and strong penetration ability, which has attracted extensive attention of researchers. [0003] The cur...

AI Technical Summary

Problems solved by technology

[0011] (1) The location of the crime and the number of criminals cannot be monitored in real time;

[0012] (2) There are many false alarms, and it is impossible to identify people who are close to the surrounding alarm area;

[0013] (3) It is impossible to analyze the behavior trajectory of the prisoner, so as to reasonably distribute the police force;

[0014] (4) Unable to strictly and accurately identify criminal identities, etc.
