Chapter 2 System Selection and Working Principle
1. RFID technology principle
RFID (Radio Frequency ID) is a “radio frequency identification” technology, which is a non-contact automatic identification technology. The basic principle is to use radio frequency signals and their spatial coupling and transmission characteristics to realize automatic identification of stationary or moving objects to be identified, and to obtain related data for identification, statistics, and processing by the back-end system. The frequencies currently used by RFID span low frequency (LF), high frequency (HF), ultra high frequency (UHF),
Multiple frequency bands such as microwave.
2. Features of RFID technology
RFID is an easy-to-control, simple, practical, and flexible application technology. Its unique advantages are beyond the reach of other identification technologies such as barcodes, magnetic cards, and IC cards. It can support both read-only work mode and read-write work mode without contact or aiming; reading can be completed in the moving process; supporting simultaneous reading and distributed data collection; storing information can be changed freely; free to work in each Under a harsh environment; a high degree of data integration can be carried out. In addition, because the technology is difficult to be counterfeited, RFID has a very high security protection capability. This technology can complete information input and processing without manual contact, optical visualization, and manual intervention, and the operation is fast and convenient.
3. RFID applicable fields
The RFID application field has already involved all aspects of people’s daily life, and will become a basic technology for the construction of the information society in the future. Typical applications of RFID include: warehouse management, logistics distribution, production line automation, product sales in the supply chain; combat support systems and inventory automation systems in the military and government industries; container and package management in the transportation field, highways Toll and parking fees; in the manufacturing industry for the visual management of production and inventory (such as tobacco, pharmaceuticals, automobiles, etc.); in the field of food safety for the traceability management of agricultural, forestry, fishery, animal husbandry and non-staple food; in the medical industry for the production and distribution of drugs , Patient care, medical waste tracking; RFID can also be used in various application fields such as book and file management, personnel and vehicle access management, positioning and object tracking, environmental perception, ticket anti-counterfeiting, and pet and wild animal tracking.
4. RFID application system composition
The radio frequency identification application system generally consists of four parts, namely, electronic tags, reading and writing equipment, middleware, and business application management software. In the application, the electronic tag is attached to the item to be identified. When the item to be identified with the electronic tag passes through the reading range, the reader will automatically take out the agreed identification information in the electronic tag in a contactless manner at a long distance, thereby realizing automatic The function of identifying items or automatically collecting item identification information.
Chapter III Implementation Plan Design
1. Implementation requirements
In view of the current management process analysis, the needs of this project are mainly reflected in the two aspects of use management and safety management, which are specifically reflected in:
General firearms warehouse: control of gun expenditures in the warehouse, supervision of guns in the warehouse

(Figure 1 Schematic diagram of process analysis)
2. Application process and implementation plan design
2.1 Application process
The general warehouse and the student team can be divided into warehouses to use the system network to connect various monitoring subsystems, and to conduct unified management in the monitoring data center.
A. First install the RFID gun passive tag on the butt. The appearance of the tag can be designed according to the butt.
(Figure 2 Schematic diagram of gun RFID tag installation)
B. The guns arrive at the general warehouse and are put into storage, and the RFID gun reader/writer is used to automatically collect data and count the incoming guns. The incoming guns are placed in 2 rows and placed in the gun cabinet. The number of guns in the warehouse can be counted through a handheld reader. Go to the outgoing guns from the trainee team’s sub-library, place the outgoing guns into the trolley in 2 rows, and automatically collect data through the RFID gun reader to count the outgoing guns. The outgoing guns are put into the gun box, and the RFID safety lock can be installed outside the gun box to ensure transportation safety.
