Overview of RFID prison personnel positioning management system

The intelligent prison personnel positioning system adopts the most advanced WSN sensor network technology in the world. It is an intelligent prison management system that corresponds the personal information in the management system with everyone in reality by safely and accurately identifying and distinguishing the detainees and managers in the prison. The system realizes the informatization of prison management in a real sense and is an effective way to realize "asking for police force from science and technology".

The system enables managers to grasp the detailed information and number of detainees in each controlled area of the prison in real time, effectively prevent the escape of detainees, reduce the probability of criminals forming parties and making trouble, secretly monitor high-risk detainees, track and follow up the occurrence of violence, and ensure the personal safety of managers and detainees to the greatest extent. In addition, the system can automatically count the number of people in the designated area and the information of the surrounding police officers on duty, dynamically monitor the outgoing personnel in the whole process, greatly reduce the work intensity of prison managers, and quickly locate the location of the police officers on duty in case of emergencies.

The universal intelligent prison management system can also be used in combination with face recognition system, intelligent access control system and video monitoring system, which can provide convenient and efficient modern means for the prison to carry out various management work of criminals.

Main indicators of RFID prison personnel positioning management system

The wristband is made of high-strength waterproof and wear-resistant ABS plastic, which defines a variety of colors to distinguish prisoners' attributes;

Prevent violent disassembly, built-in circuit design, such as shortening or violent damage, the wristband will send an alarm;

Waterproof, antistatic and flame retardant materials;

Low energy consumption design, wristband battery service life: about 1 year (1000mA lithium battery);

Frequency: 433MHz, DSSS communication mode;

Automatically register the base station, determine the heartbeat cycle and adjust the power according to the base station strategy;

Heartbeat cycle: 2s-1min adjustable (different heartbeat cycles are adopted for different sensitive areas);

Communication distance between wristband and * * *: 1-100m adjustable (adjusted according to wristband density and distance from * * *);

Number of wristbands received by a single * * * in the same cycle: 500 (cycle 1min);

It has the function of energy detection and reporting, battery low-voltage alarm, and actively report low-voltage information when the battery capacity is low;

Aes128 encryption;

The positioning base station adopts dual SOC working mode, which is stable and reliable.

Function description of RFID prison personnel positioning management system

Real time monitoring of personnel position

Personnel location information: real time display of prisoners and early warning locations on the electronic map;

Personnel movement track: display one or more personnel movement tracks in real time through electronic map;

Track the designated person: the map automatically switches with the movement of the label. Move the mouse over the label to see the current status of the label;

Personnel alarm status information: display the alarm status of personnel through different colors and shapes on the electronic map.

Alarm function

Button alarm: the prison guard wrist has an alarm button. In case of an emergency, you can press the alarm button. The monitoring center point positioning system will receive the alarm information and alarm location in time and quickly find the scene of the incident;

Wristband damage alarm: when the wristband is worn on the prisoner's hand, the prisoner can't take it off by himself, but can only cut it. If the prisoner breaks the wristband, the label will continuously send cutting alarm information to the system;

Illegal area alarm

Cross border alarm: some areas belong to the restricted area, and the alarm will be sent if the label is not allowed to enter, or some prisoners cannot leave a certain area, and the alarm will be sent once they leave;

Entrance and exit alarm: when entering and exiting some checkpoints, you can set which tags can pass in advance. When unqualified tags enter and exit the checkpoint, an alarm message will be sent;

Alarm if it is inconsistent with the management information system: the prisoner has set the room number in the system. Once the prisoner enters the wrong room, an alarm message will be sent in time.

Illegal aggregation alarm: at the specified location, the system can set the maximum allowable number of personnel. Once the preset number is exceeded, an alarm message will be sent.

Signal loss alarm: there are many factors for the disappearance of the tag (such as the battery is dead or damaged, the tag crosses the signal coverage area, etc.). The disappearance alarm condition and alarm level of the specified tag can be set. If the tag disappears, the corresponding alarm will be triggered;

Low battery voltage alarm: the lowest limit of power can be set in the system. Once the label power is lower than this limit, an alarm message will be sent;

Other alarms: add different alarm methods as required

Alarm for failure to follow the specified route: specify the travel track of a tag for a certain period of time. Once the tag is found to deviate from the specified travel track for a certain time, an alarm message will be sent;

No attendant alarm: bind the prisoner tag to the police tag, one-to-one or many to many. When the walking track of the prisoner tag is inconsistent with that of the police tag for a certain time, an alarm message will be sent.

management function

Label management

Label distribution: bind the specified personnel information with the label they wear. The label displayed in the system represents the person wearing the label.

Label replacement battery

Personnel change labels

Label grouping and classification: labels can be grouped and classified according to the actual situation.

Label configuration: such as positioning mode, security mode, start and stop configuration.

Alarm setting: set different alarm conditions for different labels.

information management

Prisoner information setting: the information of detainees can be set and managed in the system;

Police information setting: the police information can be set and managed in the system.

Commuting setting: you can set an off-duty location point. Once the staff label is placed at the location point for a certain time, it is considered to be off-duty.

Network management

Positioning base station management function: it can monitor the operation status of hundreds of positioning base stations at the same time. When the positioning base station network is interrupted, fault alarm information will be sent in time, and the positioning base stations can be configured in batch.

system management

User management: various user permissions can be set. After logging in to the system, users can perform corresponding operations and browse the contents that meet the permissions according to their own permissions.

Log management: provides detailed log generation, storage, retrieval and other functions.

Statistical report

Label warning record view all warning records of all labels or specified labels;

Check the label report, check the important alarm of the label, and count the number of times in and out of the area and residence time;

Operation history view the user's operation history;

Count the execution times of each work, the working conditions and idle time of single person, and the peak working hours of each post every day;

Conduct statistical analysis on the time and area of each alarm event;

Analyze the tag status, provide the list and location of idle police force for the reference of the leaders, and the analysis indicators are set by the user;

According to user-defined rules, the number, time period and interval of police patrols are counted by time period
