Real-time positioning supervisory system of prison

Abstract

The invention discloses a real-time positioning supervisory system of a prison. The system is a real-time positioning system based on an RFID technology. The system comprises an RFID radio frequency electronic tag, an RFID reader, an RFID antenna, an electronic map display screen and a background monitoring center. The RFID radio frequency electronic tag includes a prisoner tag and a prison police tag; and the RFID reader includes a fixed type reader and a hand-held reader. According to the system provided in the invention, an RFID antenna at a specific position is utilized to read electronic tag information including a signal intensity and arrival time and the like; a background monitoring center uses the obtained information and applies an RSSI algorithm or a TDOA algorithm to calculate a position of an electronic tag; and the position is displayed on an electronic map display screen. Therefore, the system enables real-time localization on positions of a prisoner and a prison police to be realized as well as processing can be carried out timely in case of an emergency, so that security of the prisoner and the prison police can be effectively ensured.

Description

technical field [0001] The invention relates to a real-time positioning system, in particular to a prison real-time positioning supervision system based on RFID technology. Background technique [0002] Prisons are one of the most important links in realizing the comprehensive management of social security. Any mishap in the prison will bring huge pressure and even serious consequences to the social security outside the prison. In recent years, the quality and technical level of criminals have been getting higher and higher. The height of the devil is one foot, and the height of the law is one foot. It is imperative to use high-tech means to strengthen prevention. Prisons are places where criminals are forced to be managed. Detainees are not easy to manage. To ensure the safety of society, the safety of prison guards and detainees must also be guaranteed. Monitoring the daily behavior of offenders and special circumstances is an indispensable duty of prisons. [0003] Wit...

AI Technical Summary

Problems solved by technology

But we have also seen: 1. The prison guards pay close attention to the conditions of each room, corridor, and activity area through the monitoring screen, resulting in a heavy workload for the prison guards, and it is easy to miss some minor safety hazards; 2. The traditional management model cannot Real-time monitoring of life forms makes it extremely difficult to judge the behaviors of prisoners such as fighting and fighting; 3. The traditional management mode cannot judge the specific incident location in time when an abnormal situation occurs, and cannot Notify prison guards to deal with abnormal situations
