Since prison labor tools are at risk of being used by prisoners for illegal purposes, it is necessary to manage the tools. Traditional prison tool management uses manual methods, which are not efficient. There is an urgent need to implement effective management of tools through the use of information technology and reduce the risk of illegal use of tools. Increasingly prominent problems such as insufficient police force have changed the service mode of “human defense” in the past, which is of great significance for ensuring the normal and efficient operation of prison management and speeding up the construction of prison information.
Prison tool management needs classification
The management of prison labor tools can be roughly divided into 3 categories according to different 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 tool cabinet in the workshop, distributed at work every day, and recycled after get off work.
Sporadic tool management. Such tools are usually placed in a tool warehouse, loaned out when used, and returned when used up.
Analysis of the technical schemes of pilot tool management in various prisons in the early stage
The early-stage prison pilot tool management technical solutions mainly include the two-dimensional code solution, the 900M passive RFID technical solution, and the multi-frequency RFID technical solution.
Compare the advantages and disadvantages of various solutions as follows:
Two-dimensional code scheme: The outstanding advantage of the two-dimensional code scheme is low cost. The cost of attaching a two-dimensional code label to each tool is very low. The outstanding defects are easy to be defaced and require close scanning. 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, and are not affected by contamination compared with QR code tags. In the early stage, most of the prison pilot tool management in various places adopted the 900M passive RFID solution. The actual effect in the pilot process was very unsatisfactory, mainly reflected in the low reading accuracy, the large impact of interference, and the lack of anti-dismantling alarm function. The fundamental reason why the 900M passive RFID technical solution is not ideal is that the 900M passive RFID technology is susceptible to occlusion in principle, but in the actual environment, tools are often occluded. This has caused an embarrassing situation that the cost of using 900M passive RFID technology is high, and the actual reading effect is similar to that of a two-dimensional code.
Multi-frequency active RFID technology solution. The multi-frequency active RFID technology program is a program that has been piloted in recent years. It is also a plan recommended by Guangzhou Zhuojin for 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 the user experience is better, making the prison tool management system really usable.
Tool management solidified on the work surface. Now prisons usually use chains to fix the tools on the work surface, and manually count and register them on the tool register. For the tools fixed on the table, the police officers hope to realize the real-time inventory and on-site monitoring of the tools without changing the existing management mode and increasing the burden on the 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 alert in time when the tool leaves the countertop. The tool can alert in time when it leaves the workshop.
Tool borrowing and returning management: Now prison tool borrowing and returning management basically adopts paper registration method. Police officers hope to realize self-service borrowing and returning, carry out electronic registration, and at the same time automatically read the tools in the tool cabinet in real time to prevent the tools from not being returned.
Tool inventory: Now prison tool inventory is basically manual inventory. Police officers hope to achieve manual + automated inventory, while improving efficiency, manual review to avoid accidents.
The RFID prison intelligent management system is a safe and reliable intelligent management system that distinguishes and recognizes prison inmates and managers, and associates the information of each person in the management system with each person in reality. Realize the informationization of the prison management system in a real sense! Introduce RFID technology into the prison management industry, propose an improved RFID application method for the comprehensive management of prisons, and propose the overall planning and design of the entire management system. Under the background of prison information construction, it comprehensively uses today’s advanced RFID technology, computer technology, network communication technology, automatic control technology, active detection technology, digital image encoding and decoding technology and multimedia technology to realize the functions of the prison information system.
