1. System overview
The Panlian Intelligent Prison Personnel Positioning System uses the most advanced WSN sensor network technology in the world. It can safely and accurately identify and distinguish the detainees and managers in the prison. It combines the personal information in the management system with those in reality. One-to-one intelligent prison management system for each person. This system has realized the informatization of prison management in a real sense, and is an effective way to realize “requiring 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 detainees from escaping, reduce the chance of criminals forming parties and making troubles, secretly monitor high-risk detainees, track down and follow up on the occurrence of violent incidents , To maximize the protection of the personal safety of management personnel and detainees. In addition, the system can also automatically count the number of people in the designated area and the information of police officers on duty in the surrounding area, and dynamically monitor outgoing personnel throughout the whole process, which greatly reduces the work intensity of prison management staff and can quickly locate the police officers on duty in emergencies. Location.
Panlian Intelligent Prison Management System can also be used in combination with face recognition systems, smart access control systems, and video surveillance systems, which can provide convenient and efficient modern methods for prisons to carry out various management tasks for criminals.
2. Main indicators of the system
The wristband is made of high-strength waterproof and wear-resistant ABS plastic, and a variety of colors are defined to distinguish prisoners’ attributes;
Prevent violent disassembly, built-in circuit design, such as shortening or violent damage, the wristband will send an alarm;
Waterproof, anti-static, use flame-retardant materials;
Low energy consumption design, battery life of wrist strap: about 1 year (1000mA lithium battery);
Frequency: 433MHz, DSSS communication method;
Automatically register the base station, determine the heartbeat period and adjust the power according to the base station strategy;
Heartbeat cycle: 2s-1min adjustable (different sensitive areas use different heartbeat cycles);
The communication distance between the wristband and the locator: 1-100m adjustable (adjustable according to the density of the wristband and the distance from the locator);
The number of wristbands received by a single locator in the same cycle: 500 (cycle 1min);
With energy detection and reporting functions, 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.
3. System function description
Real-time monitoring of personnel location
1) Personnel location information: real-time display of prisoners and warning locations on the electronic map;
2) Personnel movement track: Real-time display of one or more persons movement track through the electronic map;
3) Tracking the designated personnel: The map automatically switches with the movement of the label, and you can see the current status of the label by moving the mouse on the label;
4) Personnel alarm status information: Display the personnel alarm status through different colors and shapes on the electronic map.
Alarm function
1) Button alarm: The prison guard has an alarm button on the wrist. Once an emergency occurs, you can press the alarm button. The monitoring center positioning system will receive the alarm information and alarm location in time, and quickly find the scene of the incident;
2) Wristband damage alarm: When the wristband is worn on the prisoner’s hand, the prisoner can’t take it off by himself. It can only be cut. If the prisoner breaks the wristband, the label will continuously send a cut alarm message to the system;
3) Illegal area alarm
a. Cross-border alarm: Some areas are restricted areas, and an alarm will be issued if tags enter without permission, or some prisoners cannot leave a certain area, and an alarm will be issued once they leave;
b. Entry and exit alarm: When entering and exiting certain gateways, you can set up which tags can pass in advance, and an alarm message will be issued when tags that do not meet the requirements are entered and exited;
c. Alarm 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 will be sent out in time.
4) Illegal gathering alarm: At the designated location, the system can set the maximum allowable number of personnel. Once the number exceeds the preset number, an alarm message will be issued.
5) Signal loss alarm: There are many factors for the disappearance of the label (such as the battery is dead or destroyed, the label crosses the signal coverage area, etc.), you can set the disappearance alarm condition and alarm level of the specified label. If the label disappears, it will be triggered The corresponding alarm;
6) Low battery voltage alarm: You can set the minimum battery power limit in the system, and once the label power is lower than this limit, an alarm message will be issued;
7) Other alarms: add different alarm methods according to requirements
a. Failure to follow the prescribed route to alarm: specify the walking track of a certain tag for a certain period of time, once the tag is found to deviate from the specified walking track for a certain period of time, an alarm message will be issued;
b. Alarm without accompanying person: Bind the prisoner tag and the police tag, one-to-one or many-to-many binding, when the walking track of the prisoner tag is inconsistent with the walking track of the police tag, and the alarm message is sent for a certain period of time.
4. Management function
1) Label management
a) Label issuance: bind the information of the designated person to the tag worn by the person, and the tag displayed in the system represents the person wearing the tag.
b) Label replacement battery
c) Personnel replacement label
d) Label grouping and classification: Labels can be grouped and classified according to actual conditions.
e) Label configuration: such as positioning mode, safety mode, start and stop configuration.
f) Alarm setting: Set different alarm conditions for different tags.
2) Information management
a) Prisoner information setting: The information of detainees can be set and managed in the system;
b) Police information setting: The police information can be set and managed in the system.
c) On-off duty setting: A off-duty location point can be set, once the staff tag is placed at the location point for a certain period of time, it will be considered off-duty.
3) Network management
Positioning base station management function: It can monitor the operating status of hundreds of positioning base stations at the same time. When the positioning base station network is interrupted, fault alarm information will be issued in time, and the positioning base stations can be configured in batches.
4) System management
User Management: Various user permissions can be set. After users log in to the system, they can perform corresponding operations and browse content that meets the permissions according to their own permissions.
Log management: Provide detailed log generation, storage, retrieval and other functions.
Statistical report
1) Label warning records-view all labels or all warning records of designated labels;
2) View tag reports-view important alarms of tags, statistics on the number of times of entering and exiting the area and staying time;
3) Operation history-view the user’s operation history;
4) Count the number of executions of various tasks, the work situation and idle time of a single person, and the peak work period of each post every day;
5) Perform statistical analysis on the time and area of each alarm event;
6) Analyze the status of the label and provide a list and location of idle police forces for the reference of the leaders of the police. The analysis indicators are set by the user;
7) According to user-defined rules, count the number of police patrols, time periods and intervals by time period.
