RFID technology helps informatization construction of prison tools

Because there is a risk that prison labor Tools may be used by prisoners for illegal purposes, it is necessary to manage the tools. Traditional prison tool management uses manual methods, which are inefficient. There is an urgent need to use information technology to effectively manage tools and reduce the risk of illegal use of tools. Increasingly prominent problems such as insufficient police force have changed the service work model that was mainly based on "civil air defense" in the past, which is of great significance for ensuring the normal and efficient operation of prison management and accelerating the construction of prison informatization.

Classification of prison tool management needs

The management of prison labor tools can be roughly divided into three categories according to different usage scenarios:

Tool management solidified on the work surface. Such tools need to be monitored in real time whether they are on the work surface.

Management of tools borrowed and returned every day. Such tools are usually placed in the workshop tool cabinet, distributed every day at work, and collected after get off work.

Tool management for sporadic use. Such tools are usually kept in a tool warehouse, loaned out when used, and returned after use.

Analysis of technical solutions for pilot tool management in various prisons in the early stage

In the early stage, the pilot tool management technology solutions for prisons in various places mainly include QR code solutions, 900M passive RFID technology solutions, and multi-frequency RFID technology solutions.

Comparative analysis of the advantages and disadvantages of various options is as follows:

QR code solution: The outstanding advantage of the QR code solution is low cost. The cost of attaching a QR code label to each tool is very low. The outstanding disadvantages are that it is easy to be stained, requires close scanning, and the tool inventory management experience is not good.

900M passive RFID technology solution: 900M passive RFID technology uses 900M passive electronic tags, which can be pasted or hung on tools. Compared with QR code tags, they are not affected by contamination. In the early stage, prison pilot tool management in various places mostly used 900M passive RFID solutions. The actual results during the pilot process were very unsatisfactory, mainly reflected in the low reading accuracy, large impact from interference, and lack of anti-tamper alarm function. The fundamental reason why the 900M passive RFID technology solution is not ideal is that in principle, the 900M passive RFID technology is easily affected by occlusion. However, in the actual environment, tools are often blocked. This leads to the embarrassing situation that the cost of adopting 900M passive RFID technology solution is high, and the actual reading effect is almost the same as that of QR code.

Multi-frequency active RFID technology solution. The multi-frequency active RFID technology solution is a solution that has been piloted in recent years. It is also the solution recommended by Guangzhou Zhuojin based on the current situation of prison tool management. Its main disadvantage is that the label cost is high; its advantage is that it can perfectly meet the needs of prison tool management and has a good user experience, making the prison tool management system truly usable.

Tool management solidified on the work surface. Nowadays, prisons usually use chains to fix tools on the work surface, and manual inventory is recorded in the tool register at regular intervals. For tools fixed on the table, police officers hope to achieve real-time inventory and on-site monitoring of tools without changing the existing management model and without increasing the burden on police officers. It can count the number of tools in real time and upload the data to the command center and police workbench. It can give a timely alarm when the tool leaves the table. The tool can be alerted in time when it leaves the workshop.

Management of borrowing and returning tools: Currently, the management of borrowing and returning tools in prisons basically adopts the paper registration method. Police officers hope to realize Library-self-service-borrowing-and-returning-machine-source-manufacturer-UHF-touch-screen-borrowing-and-returning-machine.html target='_blank'>self-service borrowing and return, conduct electronic registration, and at the same time, automatically read the tools in the tool cabinet in real time to prevent tools from not being returned.

Tool inventory: Currently, the inventory of prison tools is basically carried out manually. The police officers hope to realize manual + automated inventory to improve efficiency while manually reviewing to avoid accidents.

The RFID prison intelligent management system is a safe and reliable intelligent management system that distinguishes and identifies prison inmates and managers, and maps each person's information in the management system to each person in reality. Realize the informatization of the prison management system in a true sense! Introduce RFID technology into the prison management industry, propose improved RFID application methods for comprehensive prison management, and propose an overall planning and design plan for the entire management system. Under the background of prison informatization construction, today's advanced RFID technology, computer technology, network communication technology, automatic control technology, active detection technology, digital image coding and decoding technology and multimedia technology are comprehensively used to realize the prison information system functions.
