Real-time positioning system of prisons based on RFID and implementation method thereof

Abstract

The invention relates to a real-time positioning system of prisons based on RFID and an implementation method thereof. The system comprises RFID base stations, prisoner wrist labels, a communication bus and a positioning management center. The RFID base station and the prisoner wrist labels are communicated in a wireless way through radio-frequency signals, and the RFID base stations are connected with the positioning management center through the communication bus. The implementation method comprises steps as follows: (1) distributed prisoner real-time positioning scheme based on the signal intensity values of the prisoner wrist labels in the RIFD base stations; (2) laying method of the RFID bas stations; (3) moving track of the prisoner is drawn, and the moving speed is computed according to precedence order, signal intensity values and time difference of the prisoner wrist labels read by the RFID base stations; and (4) the prisoner wrist labels are read by special RFID base station to judge whether special incident occurs. The real-time positioning system of prisons based on RFID and implementation method thereof can effectively carry out real-time positioning and monitoring of the prisoners.

Description

technical field [0001] The invention relates to the field of RFID radio frequency technology, in particular to an RFID-based real-time positioning system for prison personnel and an implementation method thereof. Background technique [0002] Prison is a place for detaining and reforming criminals. The purpose of prison monitoring is not only to ensure the safety of society, but also to ensure the safety of prison guards and detainees. At present, domestic prisons mostly use video surveillance systems, mainly through camera video coverage of each major security point. This digital video surveillance system has the disadvantages of high engineering cost and being easily affected by the environment. And because the video surveillance system requires manpower to monitor the monitoring screen of the control center around the clock, it directly increases the work intensity of the management personnel. When abnormal events such as prisoners attacking the police, fighting, and pr...

This kind of digital video surveillance system has the disadvantages of high engineering cost and being easily affected by the environment.

And because the video surveillance system requires manpower to monitor the monitoring screen of the control center around the clock, it directly increases the work intensity of the managers

When abnormal events such as prisoners attacking the police, fighting, and prison escape occur in the prison, the existing video surveillance technology cannot promptly and proactively inform the management personnel, and there are potential safety hazards
