The first part of the development background of RFID intelligent prison management system
With the gradual improvement of the prison management system and the continuous renewal of prison administration facilities, the ability of prisons to prevent and control various security incidents has been greatly enhanced. However, as the types of crimes and the composition of detainees become more and more complex, criminals are more revengeful, brutal and cunning, and their impetuous mentality and sense of restlessness increase. , suicide, murder, and trouble with prisons, which have extremely adverse effects on the personal safety of the police and the continuous stability of the place. Based on these facts and years of painstaking research on prison work, the RFID intelligent prison management system developed by our company, It can realize intelligent monitoring and management, prisoner information management, cross-border alarm, positioning and tracking of detainees and prisoners. It greatly improves the internal security and management efficiency of the prison, and reduces the work intensity of prison managers. At the same time, the system also has various expansion functions, such as combining and integrating with video surveillance, so that RFID technology and popular video surveillance technology are organically integrated. integrate. In addition, it can also be integrated with security monitoring systems such as face recognition, which not only enriches the functions of the entire monitoring management system, but also effectively enhances the security of the system.
The second part of RFID technology introduction
1. Introduction to RFID Technology
RFID (Radio Frequency Identification Technology) is a non-contact automatic identification technology that automatically identifies target objects and obtains relevant data through radio frequency signals. Conceptually, RFID is similar to barcode scanning. The barcode scanning technology attaches the encoded barcode to the target and uses a dedicated scanning reader to transmit the information from the bar magnetic to the scanning reader using photoelectric signals; while RFID Then use a special RFID reader and a special RFID unit that can be attached to the target, and use RF signals to transmit information from the RFID unit to the RFID reader.
2. Features and advantages of RFID technology
RFID is a flexible application technology that is easy to control, simple and practical, and especially suitable for automatic control. The identification work does not require manual intervention. It can support both read-only working mode and read-write working mode without touching or aiming; It can work freely in various harsh environments: short-range radio frequency products are not afraid of harsh environments such as oil stains and dust pollution, and can replace barcodes, such as tracking objects on the assembly line of factories; long-range radio frequency products are mostly used in traffic, and the identification distance can be adjusted. Up to tens of meters, such as automatic charging or identification of vehicles. Its unique advantages are beyond the reach of other identification technologies, mainly in the following aspects:
Easy and fast reading: The reading of data does not require a light source, and can even be carried out through the outer packaging. The effective recognition distance is larger, and the effective recognition distance can reach more than 30 meters;
Fast recognition speed: as soon as the terminal enters the magnetic field, the reader can read the information in it immediately, and can process multiple terminals at the same time to realize batch recognition;
Large data capacity: The two-dimensional barcode (PDF417) with the largest data capacity can only store up to 2725 numbers; if it contains letters, the storage capacity will be less; the RFID terminal can be expanded to dozens of K according to the needs of users;
Long service life and wide range of applications: its radio communication method makes it possible for staff to work in high pollution and radioactive environments such as dust and oil pollution. The closed packaging of the terminal greatly exceeds the life of the printed barcode;
Tag data can be changed dynamically: data can be written using a programmer, giving RFID tags the function of interactive portable data files, and writing time is less than printing barcodes;
Better security: Not only can it be embedded or attached to products of different shapes and types, but also password protection can be set for the reading and writing of terminal data, so it has higher security;
Dynamic real-time communication: The terminal communicates with the reader at a frequency of 50 to 100 times per second, so as long as the object attached to the RFID terminal appears within the effective recognition range of the reader, its position can be dynamically tracked and monitored.
The third part RFID intelligent prison management system hardware description
The RFID intelligent prison management system uses active RFID hardware devices. The equipment mainly includes: Receiver, Activator and Active Tag.
Receiver: A device for reading tag information, which can be designed to be hand-held or fixed.
receiver
Frequency band: 433MHz
Anti-collision: 200 tags (bracelets) can be identified simultaneously
Activator: activates the tag device, and can also write the ID number to the tag
Frequency: 125 KHz
Tag (Tag): The electronic tag generally stores electronic data in a predetermined format. In practical applications, the electronic tag is attached to the surface of the object to be identified. The reader can read and identify the electronic data stored in the electronic tag without contact, so as to achieve the purpose of automatic identification. Tags are divided into passive tags and active tags. Active tags are powered by batteries and have a longer read/write distance. They are also called active tags and generally have a longer reading distance. After receiving the microwave signal from the reader (reading device), the passive electronic tag converts part of the microwave energy into DC power for its own work. Generally, it can be maintenance-free, with low cost and long service life. Active tags are small, light, and have a relatively short read and write distance, also known as passive tags.

According to whether the stored information is rewritten, terminals are also divided into read-only terminals (read only) and read-write terminals (read and write). RFID prison management systems use read-write terminals. The information in the read-only terminal is written when the integrated circuit is produced, and it cannot be modified later, but can only be read by special equipment; It can be erased and written with special programming or writing equipment. Generally, the time taken to write information into the electronic terminal is much longer than the time taken to read the information of the electronic terminal. The time taken for writing is in seconds, and the time taken for reading is in milliseconds. The tag is composed of a coupling element and a chip. Each tag has a unique electronic code, which is attached to the object to identify the target object; each terminal has a globally unique ID number – UID, which is placed in the ROM when the chip is made. , cannot be modified. The user data area (DATA) is for users to store data, and can perform read, write, overwrite, and operations.

Frequency band: 433 MHz
Wireless data rate: 256kps
Battery life: 4+ years
When the person or object wearing the electronic tag (bracelet) passes through the activation range of the activator (the red man in the picture), the electronic tag (bracelet) worn by the person or object will be activated and send out information. This information includes the ID of the activator. When the receiver receives the information from the electronic tag and transmits it through the network, according to the electronic tag ID number, the activator ID number and the receiver’s IP address, it can be compared with the equipment placement information on site, and it can be concluded that “someone/someone” The record of objects passing through a monitoring area at a certain time can realize the tracking and monitoring of people or objects.
