The RFID roll call management system is an intelligent solution developed by Beijing Chuangyi based on years of indoor personnel positioning technology research and application practice, which is suitable for the dynamic management of prison personnel. This system is designed in accordance with the supervision site and operates independently. Through RFID radio frequency identification technology, the detainees are equipped with special electronic identification tags, so that everyone can be automatically identified by the system and accept the precise auxiliary management of the system.
1. Construction background
In order to prevent detainees from escaping, the supervisory unit generally adopts regional entry and exit reports and call management in work rooms. That is to say, when detainees need to move across regions, they need to report the number of persons on the move, whereabouts, and the police officers and other information to the prison command center, and they can move only after obtaining the approval of the command center. In the labor process, it is also necessary to count the number of detainees in the plant regularly and report it to the command center. However, under the traditional management model, people counting, reporting, and statistics are all done manually, which has caused problems such as long management process, heavy workload of police officers, low management efficiency, and labor impact. Therefore, breaking through traditional management shortcomings through technical means is the solution 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 tags, wristband-type electronic tags, positioning identification antennas, fixed base station readers, mobile handheld readers, Communication gateway, management platform software, etc.
The system topology diagram is as follows:
1. System workflow
1.1 The hand-held read-write terminal device directly reads the identity tags of the detainees, and then connects the computer through the data line to upload the collected rollover 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 antenna triggers the tag to work, the tag signal is received by the base station reader and sent to the management background via wired means.
Install the positioning antenna in the prison room and the entrances and exits of important passages, and match the ID of the positioning antenna with its deployment location in the background software. The detainee wears a wristband tag, and 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 tag (the effective range of the positioning antenna can be adjusted according to the size of the antenna) , The tag reports the ID to the nearest radio frequency signal receiving base station in real time, and the background software knows from the ID that the person wearing the wristband tag is at the location of the locator. According to 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 positioning in the prison area
It is mainly used for small activity spaces such as prison cells and ventilation rooms. The cell is used as a unit to manage by name and location. The automatic and timed roll call positioning management can be carried out through the fixed positioning read-write equipment arranged in each room, and the prison guards can also carry out mobile roll call management through the handheld management terminal.
2.2 Roll-call positioning outside the prison area
Mainly in large collective activity spaces such as labor reeducation workshops, collective activity playgrounds and labor classrooms. These places have large activity areas and large numbers of people. Fixed positioning reading and writing equipment can be arranged at the door, and the equipment can automatically perform operations when personnel pass by. Roll call statistics instead of waiting in line. In addition to arranging equipment at the door, fixed reading and writing equipment can also be arranged at other locations within its range of activities, such as ceilings, ceilings, walls, etc., to conduct automatic and regular roll-call management of detainees in real time.
2.3 Point and name positioning of channel entrances and exits
Fixed read-write devices are arranged at these main entrances and exits. When the detainees pass by these places, there is no need to line up. When they are walking freely, the system will automatically roll their names and count them in real time.
3. Main functions of the system
3.1 Management of prisoners in custody: The system conducts naming statistics on prisoners in custody through positioning reading and writing equipment, including the number of online personnel, detailed identities, time and location, dynamic changes in the positioning area, etc., as well as real-time positioning management in the prison.
3.2 Prison guard management: The system will perform real-time positioning and tracking monitoring of the prison guards when they enter the recognition range of the positioning device during the inspection process with a card-type electronic tag. To regulate the role of supervision. The card 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 Object tool management: Bind anti-dismantling electronic tags to the object tools, and after the prisoner has participated in the labor, the labor tools used by the prisoner shall be counted in a timely manner to prevent the prisoner from hiding in private and causing accidents.
4. System hardware composition
4.1 Fixed reading and writing equipment: identification distance can be far or near, 1-200 meters adjustable, identification direction 90-360° adjustable, strong identification ability, can read 200 tags at a time, and is not easy to be interfered by external factors . After the equipment reads the information, it is transmitted to the computer management client terminal in real time via the network, and then sent to the command center and other departments.
4.2 Hand-held read-write terminal: Mobile roll call equipment tool, the identification direction is not restricted, 200 tags can be read at a time, and the collected information can be transmitted to the computer management terminal through the data cable, and then sent to the superior and other departments.
4.3 Management tags: Police officers use card tags. Detainees use card-type tags for management, and they are prone to mutual borrowing, exchange, and loss. Therefore, it is recommended that detainees prefer wristband and wristband tags, anti-dismantling alarms, tracking the whole process, and grasping the situation in time.
5. System features
5.1 Real-time management: After the detainees are called, the system can quickly and timely feedback to the customer management end, there is no delay status, so that the status of the detainees can be accurately grasped. The system can roll the names of the prisoners one by one, or quickly roll the names in batches. You can roll the call from a short distance or from a long distance.
5.2 Automatic and mobile combined management
The system can automatically recognize the roll call when the detainee passes through a fixed positioning read-write device, and it can also perform a barrier-free mobile roll call without affecting the prisoner’s work. The police officer holds a mobile read-write terminal device to complete it. The system can perform a roll call and count regularly and from time to time, and monitor the number, identity, location and other information of detainees in a timely manner.
5.3 Video linkage function
During the roll call positioning process, nearby cameras can be called to assist work at any time to check the status of the personnel within the roll call range. If an abnormal situation occurs during the roll call process, the system will automatically call the corresponding camera linkage work.
3. Construction significance
1. Improve management efficiency. Strengthen the police with science and technology, liberate the police force, promote the standardization of police affairs, and transform the police work from manual management to an informationized, automated, and intelligent management method. Through automatic identification and statistics of personnel entry and exit, manual links are reduced, management time is shortened, human error is reduced, supervision measures are strengthened, and management is more timely and in place.
2. Improve labor efficiency. The automatic roll call system eliminates the need to wait in line, greatly shortening the roll call inspection time of detainees and saving 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, the unified collection and storage of various useful management information, and sharing within the system, play a huge role in the entire public security, judicial management and even the construction of a harmonious society.
