The application of electronic tags for military firearms and military materials to achieve informatization management
As the future direction of the military’s efforts, informatization construction, regardless of which branch it belongs to, has included the development and utilization of information resources as the core informatization construction work on the agenda of military construction.
The new military revolution centered on information technology is causing a profound change in the military field. The essence of this change is the transformation from the mechanized military form of the industrial society to the informationized military form of the information society. With this historic change, military informatization has become an important means of accelerating the modernization of the military, and it has also become an important part of the modernization of the military.
RFID (Radio Frequency Identification) technology is an automatic identification technology that has matured from the 1980s. It has many advantages over other identification technologies such as traditional barcodes. It stores a larger amount of information, and its storage content can be dynamically changed. , Reading the target is farther away, and can identify multiple targets at the same time. Its automatic and real-time recognition capability is especially suitable for the military management requirements of personnel, vehicles, ordnance, and materials.
The informatization management of ordnance and other military supplies is precisely the weak link in the overall informatization construction of our army. Most warehouse management mainly relies on manual operations, which cannot meet the requirements of fast and accurate guarantees in future wars. Therefore, make full use of RFID technology to realize ordnance The automated management of armaments and materials is a key practice of our military in the field of logistics information, and it is also the basis for realizing the visualization of the entire process of material support in the future, establishing a “precision” battlefield material support system, and realizing scientific and rapid material support decision-making.
RFID system overview
The long-distance radio frequency automatic identification system uses radio frequency signals to realize contactless information transmission through spatial coupling and realizes the automatic identification of items in different states (moving, stationary) through the transmitted information, thereby realizing the automated management of targets.
The system can carry out network management according to different management requirements, and realize the network application of long-distance radio frequency identification. The system’s reading equipment adopts ultra-high frequency shortwave frequency (transmitting and receiving frequency 902-928MHz) to realize reliable full-duplex wireless data communication.
The electronic tag uses an embedded microprocessor, and under the control of the embedded software, it realizes functions such as sleep, wake-up, decoding, encoding, communication and information collision processing. The reading device can identify multiple targets at the same time; the system can reliably identify 100km/ h fast-moving target, the recognition distance is not less than 5 meters, the recognition is no blind zone, no microwave radiation harm to the human body, strong signal diffraction and penetration, high information security and confidentiality performance, easy operation and use, and can be adapted to a variety of different Application Environment.
This system is designed for the automation and informatization of the management of military firearms and military materials, and is mainly used for automatic identification management of military firearms entering and leaving the warehouse.
The system uses modern computer technology and RFID technology to realize automatic identification and information management of military firearms. This system can effectively, accurately and intelligently automatically identify, collect, record, upload information on firearms entering and exiting the warehouse, and perform maintenance information on firearms. Quick inquiry and statistics have established a digital information management system for military material management.
The automatic identification management system of military firearms mainly consists of three parts: radio frequency automatic identification equipment, automatic firearm identification electronic tags, and background management system. The back-end management system is composed of a firearms electronic label issuance management module, a firearms warehousing automatic identification module, a user and user authority management module, a system management module, and a data statistics query module.
The system functions are as follows:
□ Automatically identify and register firearms information when the firearms are in and out of the warehouse, such as the name of the firearm, the model of the firearm, the number of the firearm, the time of entry and exit, the person who handles it, the person who approves, etc.; and control the flow of firearms;
□ The system will verify the identity and authority of the applicant. When there is a discrepancy, the system will automatically alarm;
□ Provide query, analysis and statistics, printing and other functions to improve the level of information management;
System flow
□ Due to the special nature of the military, there are many urgent tasks, plus the daily maintenance of firearms, etc. The specific situations are very different, and it is difficult to achieve one-to-one correspondence between firearms and commanders. Therefore, in the management of firearms, consideration should be given to establishing a company platoon leader responsibility system. , That is, taking guns and returning guns are based on the company platoon. Each company platoon leader is issued an identification card, which is presented when the gun is taken or returned, and the card number is recorded into the system, and the card is taken or returned to the system. Of firearms and equipment to establish associations for easy management. (Note, the company platoon leader does not need to be present in person during each operation, and other commanders can be assigned to operate with a card.)
□ During operation, the firearm administrator first logs in to the system, and this login identity can be used as the “approver”.
□ The officers and fighters who carried out the operation of retrieving and returning the guns show the company platoon leader identification card, and their identification information is automatically registered (if the identification fails, such as the card expires, etc., the request can be rejected).
□ After identification, personnel can enter the firearms depot. During the process of taking out the firearms, the system will automatically scan and identify the firearms and equipment when the personnel take the guns out of the door of the firearms depot. When the warehouse door, the system automatically scans and recognizes the firearms and equipment. The identified firearms information is associated with the previous personnel’s identity, and the authority is judged, and the judgment is correctly recorded in the database. In addition, in the gun retrieval process, after the system automatically recognizes the firearms and equipment, the firearms administrator selects the type of reason or enters a note, etc. The information is saved in the database together with the identification information.
□ According to the information scanned and identified by the system, if irregular operations are found, such as wrongly taking firearms and equipment belonging to other companies, the system will alarm.
System product composition
The system product consists of a software system and a hardware system. The software system mainly refers to application software. If a handheld data acquisition device is used, the software system also includes an embedded software part, which is mainly used to complete information collection, processing and transmission. The hardware system is composed of electronic tags, antennas, readers and PCs, which are used to complete information collection, identification and running application software.
□ Electronic tag: attached to the identified object to identify the object.
□ Antenna: used to transmit and receive radio signals;
□ Reader: used to collect tag information.
□ PC: Run application software.
According to user needs, in order to achieve accurate reading and prevent cross-reading, we choose passive single-frequency electronic tags.
□ The working frequency of the tag is UHF frequency band, 915M;
□ The memory of the label adopts EPC CLASS 1 Gen2 standard;
□ For the complex situation of monitored items, special materials are used for packaging, which is suitable for the surface of metal items.
The label pasting method can refer to the following:
□ For machine guns and submachine guns, the label can be encapsulated on the strap of the gun.
□ For pistols, the label can be packaged in a pendant or packaged on the pistol’s connection cord.
□ For bullets, the label can be packaged on the bullet bag or pasted on the magazine.
The reader/writer plays a pivotal role in the RFID system. The frequency of the reader/writer determines the working frequency band of the RFID system, and the power of the reader directly affects the distance of the RFID system. Generally speaking, a high-frequency tag has a greater reading distance, but it requires a greater electromagnetic wave energy output by the reader. A high frequency tag can be read within a distance of 3 to 8 meters.
