1. System background
Prison inmates’ automatic attendance system is a special case of personnel’s automatic attendance. It mainly usesRFIDRadio frequency technology and computer technology.
Prison is a place to help prisoners correct their mistakes and carry out labor reforms, but the prisoners themselves may not be able to realize this, and thus have conflicting thoughts on the management of the prison. They will not obey the management of the managers and often do not take the initiative to swipe their cards to check attendance. , Forming parties, making troubles, fighting, and confronting managers. This has brought many difficulties to the management of prisons. For example, the attendance system inside is an assessment of prisoners every day, and it can also reflect the performance of prisoners in this period of time, because the performance will affect the length of time they stay in it. Those who do not obey the management will not consciously swipe their cards, but they have to swipe their cards, which hinders management.
It is precisely because of this situation that the company introduced the solution of “Prison Staff Automatic Attendance System” after launching the “Home-School Communication” and “Elderly Home Staff Management System” using 2.4G long-distance radio frequency cards.
The system can also be used in conjunction with the prison intelligent management system, face recognition system, intelligent access control system, and video capture system. It can provide convenient and efficient modern methods for the management of labor camp personnel in labor camps.
2. System Brief
Using this system, managers can effectively manage the attendance of prisoners. This process is all automated. Inmates do not need to take the initiative to swipe their cards every day, which brings convenience to prisoners and makes those prisoners who do not cooperate with the management work lose trouble. Opportunities can also reduce the occurrence of conflicts between prisoners. This is conducive to the management of the work, so that the prison management work is intelligent.
1. System composition
Electronic tags: Tag cards made of active electronic tags produced by Boao, with an identification distance of 2-80M, and advanced anti-collision technology, which can identify more than 200 tags per second at the same time. The shape of the wrist is worn on the prisoner’s wrist, and it is made tamper-proof. If the prisoner wants to remove it, the police will call the police. It is also possible to record the identity information of the reeducation-through-labor personnel in the electronic tag, including name, age, gender, height and physical characteristics, and the crimes committed.
Card reader: It adopts the long-distance card reader produced by Boao, which can be used to automatically read the information of the radio frequency card. It can recognize 200 cards at the same time, the reading distance is 5-80M and the distance can be adjusted. Using channel isolation technology, multiple devices do not interfere with each other, advanced anti-collision technology, support multi-tag reading and writing. Installed in the attendance area to realize the reading of label information.
Attendance Center: It is composed of computers and software systems. So as to realize the supervision of prisoners’ attendance and make prison management.
2. The working principle of the system
The prisoner enters the attendance area with a wrist tag card every day. Because it is an active electronic tag, the working method is active, that is, the ID number information is continuously transmitted to the outside. The card reader will read the tag ID information, and the card reader will transmit the signal to the computer via RS485 or RS232, and the detailed information of the prisoner can be seen by comparing the ID number database. The system uses time to check attendance. The morning attendance is based on the time read once, and the night attendance is based on the time of the last reading. In the specific design, set the time zone, for example, when the attendance starts in the morning, and the attendance ends at the time in the afternoon. In this way, the attendance is accurately realized.
Three, system characteristics
1. Excellent performance
Active identification card, high recognition reliability, 100% front-end recognition rate.
The active card recognition distance is long (2-80 meters), this solution does not need to use a handheld card reader to be placed next to the tag, which can fully realize fully automatic recognition
Extremely high anti-collision performance (can recognize 300 active cards at the same time), high recognition stability (error rate is less than one hundred thousandths), truly achieve no error codes and no missing cards
It can track and locate in real time, and automatically monitor the attendance of prisoners
Has a destruction alarm function to prevent prisoners from dismantling at will
Improve the management level, centralized management, distributed control; effective management of prison inmates has improved the intelligence and scientific nature of management.
2. High security and stability
High reliability: it can operate normally within the ambient temperature of -40℃-+85℃ (MTBF≥70000 hours), especially in the low temperature in the north and high temperature in the south, it has more advantages, and it can effectively resist high dust in the air in harsh environments It can ensure the normal use of the equipment in environments such as humidity and humidity.
High anti-interference, no special requirements for the surrounding environment, strong environmental adaptability
The device failure rate is minimized and the operation is reliable
Ultra-low power consumption: long service life, low average cost, maintenance-free, safe and healthy to the human body, no electromagnetic radiation pollution, safer to use. The working mode of the microwave module can be configured, and the transmission power can be adjusted.
3. System implementation benefits
Improve the management level of prisons and realize intelligent management
Changed the traditional management mode and reduced the wastage of manpower
Reduced the probability of prisoners forming parties and making troubles, fighting and fighting
Take prison management to a higher level, help reform prisoners and build a harmonious society
Four, system function
The prison inmate attendance system can carry out real-time monitoring and management of prisoners’ daily attendance status, and has functions such as selection tracking and query.
Tracking: According to the information collected by the electronic tag worn on the prisoner’s wrist, the attendance of each prisoner can be tracked and managed, and problems can be discovered and solved in time.
Inquiry: Inquire about the prisoner according to the tag ID, you can find out the name of the prisoner, the number of the prisoner, what happened, the attendance status, etc.
Modification: The basic information of the prisoner corresponding to the tag number can be modified and updated. The modified information includes: attendance, education period, etc.
Delete: delete the information of prisoners who are no longer serving their sentences.
Additional functions: consumer electronic management in prisons, combining electronic consumption withelectronic label(Identity Watch) The combination of the two allows prisoners to wear it. This will allow prisoners to consciously protect the identity watches they wear, and also reduce disputes between prisoners due to money.
Use this system to refer to and compare:
Before implementation: The use of traditional means of attendance not only consumes manpower but also makes it difficult to fully manage.
After implementation: the use of this system can reduce the consumption of management manpower, realize intelligent management, and reduce the labor intensity of management personnel.
Before implementation: Prisoners must take the initiative to check attendance by swiping their cards every day, which has caused conflicting thoughts and behaviors of prisoners and hindered the management of prisons.
After implementation: The system uses an active radio frequency card, and the working method is active. It is not necessary for the prisoner to take the initiative to check on work attendance every day. As long as the prisoner carries a wrist electronic tag through the attendance area every day, the card reader installed in the attendance area can automatically Read the tag information to realize the attendance of the prisoner. This not only reduces the conflicting behavior of the prisoners but also facilitates the management of the managers.
Before implementation: The traditional prison management model requires a lot of manpower and material resources, which increases the financial burden for the government.
After implementation: the application of new technologies makes the management of prisons intelligent, reduces the demand for management manpower, realizes the need for police force from science and technology, and saves the government’s human resources and financial expenditures.
