1. Current situation of prisons
The prison system is a place where all prisoners are detained, including prisons, detention centers, detention centers, etc., who are sentenced to suspended death, life imprisonment, and fixed-term imprisonment. Penalties are executed in prisons.
With the all-round development of society and the impact of social transformation on people’s lives and thinking, various conflicts of interest have intensified, and a large number of contradictions have quickly emerged. With the increasing complexity of crime types and detainees, criminals The revenge, cunning, impetuousness and restlessness of the prisoners have increased. If they are not careful, they will take risks, wait for opportunities to take hostages, escape, and commit suicide, which brings extremely disadvantages to the personal safety of the prison police and the continued stability of the premises. Influence.
How to prevent the recurrence of such incidents and how to effectively guarantee the safety of judicial work will surely become an important topic, and it is an urgent issue that must be addressed.
2. System application principle
The system is mainly to track and locate the prisoners’ activities or to control the area, and at the same time to grasp the distribution of prison guards, which requires a wireless location that represents their identity.RFIDTags, tags continuously and automatically transmit wireless signals, and configure positioning base stations that can automatically identify these tags in each area;
The positioning tag and the positioning base station can communicate with each other and transmit wireless signals to form a wireless monitoring network. No matter where the personnel go, the nearby positioning base station can receive the wireless signal sent by the positioning RFID tag;
The positioning base station transmits the received positioning tag information to the computer of the control center through the system, and displays the current location of the person in a two-dimensional image on the computer screen;
According to the actual situation of the prison, the system pre-sets the activity area and activity time of the relevant personnel. Once the specified range or time is exceeded, the system can immediately determine the abnormality and trigger an alarm. The staff on duty can instantly see the abnormal personnel and the time on the screen. Location, take corresponding measures.
3. System function
3.1 Real-time monitoring of personnel
The electronic map displays the locations of all detainees and police officers in real time. The monitoring personnel can dynamically grasp the number of personnel and real-time distribution. Move the mouse to the label personnel icon to view detailed personnel information.
3.2 Personnel search and location
Enter the person’s name or number to quickly locate the location of the prisoner or police officer you want to find.
3.3 Illegal assembly alarm
In the designated area, the system can set the maximum allowable number of personnel. Once the number of people exceeds the preset number, an alarm message will be sent out immediately.
3.4 Forbidden zone intrusion alarm
Some areas are restricted areas. Unauthorized entry of location tags will cause an alarm. When entering and exiting certain gates, you can set up which location tags can pass in advance. When the location tags that do not meet the requirements enter and exit the gate, an alarm message will be issued ; Or some areas can only be entered at a certain time, if entering at other times, it will be regarded as illegal intrusion, and an alarm will also be issued.
3.5 Unauthorized departure alarm
It is stipulated that certain prisoners cannot leave a certain area, or cannot leave a designated place within a certain period of time. Once they leave, an alarm will be issued.
3.6 Active track playback
The system records the location and time of all personnel passing through all the time, can track and replay the personnel’s movement route, and master its detailed activity route and time.
3.7 Automatic ward rounds and roll call
The staff can be counted automatically in each prison at a fixed time, showing the number of people who should have arrived, the number of people who have arrived, and the number of people who have not arrived. If the personnel have not arrived, an alarm will be issued in time to remind the prison guards to find and locate the unreached personnel in time to prevent accidents. The prisoner has set the room number in the system. Once the prisoner enters the wrong room or leaves the room during an irregular time, an alarm message will also be sent.
3.8 Out of supervision and alarm
Bind the prisoner location tag with the police location tag, which can be bound one-to-one or many-to-many. When the walking trajectory of the prisoner and the police are inconsistent for more than the allowed time, the system will send an alarm message. Or limit the distance between the prisoner and the police. When the distance between the two is more than the specified distance, the system will send an alarm message.
3.9 Emergency call
Prison guards and prisoners locate tags with alarm buttons. Once an emergency occurs, you can press the alarm button. The monitoring center can receive the alarm information in time, know the location of the alarm, and provide support quickly.
3.10 Temporary supervision outside prison
In the case of temporary medical treatment and escort outside the prison, the entourage guards carry hand-held GPS positioning equipment with them, and can track the dynamic information of the escorted persons at any time outside the prison in real time.
3.11 Remote monitoring and inspection
The system can be operated through the Internet to realize remote management and monitoring, and managers can check the prison situation at any time even if they are not in the prison.
4. Application prospects
The Wei Lixin Intelligent Prison Staff Positioning Management System adopts the most advanced wireless identification technology at present. The wireless positioning technology is specially designed and developed for the needs of the prison staff to manage and monitor the situation of the prison staff. A set of software and hardware combined application systems. It is an intelligent prison administration management system that distinguishes and identifies detainees in a safe and reliable manner, and corresponds to each person’s information in the management system one-to-one with each person in reality, realizing the informationization of prison management in a true sense.
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, and track down and follow up on violent incidents. If it happens, the personal safety of management personnel and detainees is guaranteed to the utmost extent. 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 entire process, which greatly reduces the work intensity of prison managers and can quickly locate the police officers on duty in the event of an emergency. Location.
The intelligent prison personnel positioning management system can also be used in conjunction with face recognition systems, intelligent access control systems, video surveillance systems, visitor management, and high-voltage pulse electronic fences. It can provide convenient and efficient modern methods for prisons to carry out various management tasks for criminals. .
