Because of the risk of prison labor tools being used by prisoners for illegal purposes, it is necessary to manage the tools. Traditional prison tool management adopts manual method, which is inefficient. It is urgent to use information technology to realize effective management of tools and reduce the risk of illegal use of tools. The increasingly prominent problems, such as the shortage of police force, have changed the service mode of "civil air defense" in the past, which is of great significance to ensure the normal and efficient operation of prison management and accelerate the construction of prison information.

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

1. Tool management solidified on worktable. Such tools need to monitor whether they are on the worktable in real time.

2. Manage the tools borrowed and returned every day. This kind of tools are usually placed in the tool cabinet of the workshop. They are distributed and recycled at work every day.

3. Management of sporadic tools. This kind of tools are usually placed in the tool warehouse, lent out when in use, and returned when used up.

Analysis on the management technology scheme of pilot tools in prisons in early stage

In the early stage, the technical solutions of prison pilot tool management mainly include two-dimensional code solution, 900m passive RFID technology solution and multi frequency RFID technology solution.

The advantages and disadvantages of various schemes are analyzed as follows:

Two dimensional code scheme: the prominent advantage of two-dimensional code scheme is low cost, the cost of pasting two-dimensional code label on each tool is very low, the prominent defect is that it is easy to be defaced and needs close scanning, and the tool inventory management experience is not good.

900m passive RFID technology solution: 900m passive RFID technology adopts 900m passive electronic tag, which can be pasted or hung on the tool, compared with QR code tag, it is not affected by contamination. In the early stage, 900m passive RFID scheme is mostly used in the management of prison pilot tools. Its advantages are that it can perfectly meet the needs of prison tool management, and the user experience is good, so that the prison tool management system can really be used.

Tool management solidified on worktable. Nowadays, the prison usually uses chains to fix the tools on the worktable, and the manual inventory is registered on the tool register. For the tools fixed on the table, the police hope to realize the real-time inventory and on-site monitoring of the tools without changing the existing management mode and increasing the burden of the police. It can count the number of tools in real time and upload the data to the command center and the police station. When the tool leaves the table, it can give an alarm in time. When the tool leaves the workshop, it can give an alarm in time.

Tool borrowing and returning Management: at present, the prison tool borrowing and returning management basically adopts the paper registration method. The police 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 returning.

Tool inventory: now the prison tool inventory is basically manual inventory, police hope to achieve manual + automatic inventory, improve efficiency at the same time, manual review, avoid accidents.

RFID prison intelligent management system is a kind of safe and reliable intelligent management system which can distinguish and identify prison prisoners and managers, and make everyone's information in the management system correspond to everyone in reality one by one. Realize the informatization of prison management system in a real sense! This paper introduces RFID technology into prison management industry, puts forward an improved RFID application mode for prison comprehensive management, and puts forward the overall planning and design scheme of the whole management system. Under the background of prison information construction, the advanced RFID technology, computer technology, network communication technology, automatic control technology, active detection technology, digital image encoding and decoding technology and multimedia technology are comprehensively used to realize the functional requirements of prison information system.
