　　RFID electronic prison industry application

　　The RFID roll call management system is an intelligent solution developed by Beijing Chuangyi based on years of research and application practice of indoor personnel positioning technology, which is suitable for dynamic management of prison personnel. The system is designed in accordance with the supervision site and operates independently. Through RFID radio frequency identification technology, detainees are equipped with specially-made electronic identity tags, so that everyone can be automatically identified by the system and receive precise auxiliary management by the system.

　　1. Construction background

　　In order to prevent detainees from escaping, supervisory units generally adopt regional entry and exit reports and work room roll call management. That is, when detainees need to move across regions, they need to report the number of people, whereabouts, and police officers to the prison command center and obtain the approval of the command center before they can move. During the labor process, it is also necessary to regularly count the number of detainees in the factory building and report them to the command center. In the traditional management mode, the counting, reporting, statistics and other tasks are all done manually, resulting in long management process, heavy workload for police officers, low management efficiency, and labor impact. important directions for these issues.

　　2. Scheme design

　　The system consists of three levels of electronic tag identification, information transmission, and tracking management, including: card-type electronic identity tag, wristband-type electronic tag, positioning and identification antenna, fixed base station reader, mobile handheld reader, Communication gateway, management platform software, etc.

　　The system topology is as follows:

　　1. System workflow

　　1.1 The hand-held reading and writing terminal device directly reads the identity tag of the detained prisoner, and then connects the computer with the data line to upload the collected roll call data to the platform server, and then transmits it to other departments by the software platform. The process is relatively simple.

　　1.2 In the case of fixed reading and writing equipment, the detainee carries the tag into the antenna identification range. After the tag is triggered by the antenna to work, the tag signal is received by the base station reader and sent to the management background by wire.

　　Install the positioning antenna in the dormitory room and the entrances and exits of important passages, and match the ID of the positioning antenna with its deployment position in the background software. The detainee wears the wristband wristband tag. When passing through the identification range of the positioning antenna, the locator sends a low-frequency induction signal with its own ID to the wristband wristband tag (the effective range of the positioning antenna can be adjusted according to the different sizes of the antenna) , the tag reports the ID to the nearest radio frequency signal receiving base station in real time, and the background software thus knows from the ID that the person wearing the wristband tag is at the location of the locator. According to the actual business requirements, the roll call positioning system can be implemented according to different areas and objects.

　　2. Regional roll call positioning

　　Prisons usually adopt the method of regional management, that is, the management area is delimited by building layout or floor rooms.

　　2.1 Roll call and positioning in the prison

　　Mainly in the small activity spaces such as the prisoner's dormitory and the release room, the dormitory is used as a unit for roll call and positioning management. Automatic and timed roll call and positioning management can be carried out through fixed positioning reading and writing equipment arranged in each room, and prison guards can also carry out mobile roll call through hand-held management terminals.

　　2.2 Roll call positioning outside the prison area

　　Mainly in large collective activity spaces such as labor camps, collective activity playgrounds, and labor classrooms. These places have large activity areas and a large number of people. Fixed positioning reading and writing equipment can be arranged at the door. Count by roll call instead of waiting in line. In addition to the equipment at the entrance, fixed reading and writing equipment can also be arranged at other locations within the scope of their activities, such as ceilings, ceilings, walls, etc., to conduct automatic and timed roll call management of detainees in real time.

　　2.3 Channel entry and exit roll call positioning

　　Fixed reading and writing devices are arranged at these main entrances and exits. When detainees pass through these places, there is no need to queue up. In the case of free walking, the system will automatically count them in real time.

　　3. Main functions of the system

　　3.1 Prisoner management: The system conducts roll call statistics on prisoners through positioning and reading devices, including the number of people online, detailed identities, time and place, dynamic changes in the positioning area, etc., as well as real-time positioning management in the prison.

　　3.2 Prison guard management: When the prison guards wear card-type electronic tags during the patrol process, when they enter the identification range of the positioning equipment, the system will conduct real-time positioning, tracking and monitoring of the prison guards. to normative supervision. The card-type label has a button for help function. When the police encounter an emergency, they can directly press the button above to call for help in time.

　　3.3 Items and tools management: Bind tamper-evident electronic tags to items and tools, and after detainees have finished labor, the labor tools they use should be counted in time to prevent prisoners from hiding privately and causing accidents.

　　4. System hardware composition

　　4.1 Fixed reading and writing equipment: the recognition distance can be far or near, adjustable from 1 to 200 meters, and the recognition direction can be adjusted from 90 to 360 degrees. . After the device reads the information, it is transmitted to the computer management client terminal in real time through the network, and then sent to the command center and other departments.

　　4.2 Hand-held reading and writing terminal: mobile roll-calling device tool, the recognition direction is not limited, and it can read 200 tags at a time. After collecting the information, it can be transmitted to the computer management terminal through the data line, and then sent to the superior and other departments.

　　4.3 Manage labels: Police officers use card labels. The use of card-type labels for detainees has many disadvantages, and is prone to mutual borrowing, exchange, and loss. Therefore, it is recommended that detainees prefer wristband-type tags, tamper-evident alarms, full tracking, and timely grasp of the situation.

　　5. System features

　　5.1 Real-time management: After the detainees are named, the system can quickly and timely feedback to the client management terminal, and there is no delay, so that the status of the detainees can be accurately grasped. The system can call the prisoners one by one, or quickly call them in batches. Calling can be done at close range or from a distance.

　　5.2 Automatic and mobile combined management

　　When the detainees pass through the fixed positioning reading and writing equipment, the system can automatically identify the roll call, and can also carry out barrier-free mobile roll calling without affecting the labor of the prisoners, which is completed by the police officers with hand-held mobile reading and writing terminal equipment. The system can carry out regular and irregular roll call, and monitor the number, identity, location and other information of detainees in a timely manner.

　　5.3 Video linkage function

　　During the roll call and positioning process, nearby cameras can be called at any time to assist in the work, and the status of personnel within the roll call range can be checked.

　　3. Construction Significance

　　1. Improve management efficiency. Technology strengthens the police, liberates the police force, promotes the standardization of police affairs, and transforms the police work from manual management to an information-based, automated, and intelligent management method. Through the automatic identification and statistics of personnel entry and exit, manual links are reduced, management time is shortened, human errors are reduced, and supervision measures are strengthened to make management more timely.

　　2. Improve labor efficiency. The automatic roll call system eliminates the need to wait in line, greatly shortens the time for roll call and inspection of detainees, and saves labor time.

　　3. Conducive to the construction of a big data system for prison administration and police information management. Using the advanced technology and equipment of this system, all kinds of useful management information can be collected and stored in a unified manner, and shared within the system, which has a huge effect on the entire public security, judicial management and even the construction of a harmonious society.
