Indoor prisoner positioning system based on fingerprint identification

Abstract

The invention discloses an indoor prisoner positioning system based on fingerprint identification. The system comprises an RFID wristband and a base station; the RFID wristband stores label information composed of identity information and fingerprint information of a prisoner, logs and collects the fingerprint information of a person who wears the wristband at present, matches the fingerprint information with stored fingerprint information of prisoners, and sends an RF signal via label information when matching succeeds; and the base station receives the RF signal from the RFID wristband, obtains the label information from the RF signal, detects the intensity of the received RF signal of the RFID wristband, calculates the distance from the RFID wristband to the base station, and determines the indoor position coordinate of the person who wears the wristband according to the distance. The person who wears the wristband at present can be verified via fingerprint identification, the position of the person relative to the base station can be positioned accurately after that verification passes, the base station can carry out identity identification and positioning on prisoners via a simple structure, and the security guard management level of prison information construction is improved comprehensively.

Description

technical field [0001] The invention relates to an indoor positioning system for prison personnel based on fingerprint identification, belonging to the technical field of indoor positioning. Background technique [0002] Prison personnel positioning management system is an important embodiment of prison information construction. The system applies Internet of Things technology to law enforcement processes such as criminal roll call, entry and exit registration, etc., which can enable prison managers to grasp the detailed information and number of detainees in each controlled area of ​​the prison in real time, effectively prevent detainees from escaping, and reduce the possibility of criminals forming cliques and making troubles. chance, secretly monitor high-risk detainees, trace and follow up the occurrence of violent incidents, and maximize the protection of the personal safety of managers and detainees. [0003] RFID (Radio Frequency Identification) is a technology that ...
