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 2.45GHz) integrated high frequency (transmitting frequency 125K) 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 200km/ 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 of military firearms, access control management and information management. This system can effectively, accurately and intelligently automatically identify, collect, record, upload information on firearms entering and exiting the warehouse, as well as the information on firearms. Maintain information for rapid query and statistics, thereby establishing 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, 125K entry and exit 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:
• Automatic identification and registration of 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, and the daily maintenance of firearms, etc. The specific circumstances are very different, and it is difficult to achieve one-to-one correspondence between firearms and commanders. Therefore, the establishment of a company platoon leader responsibility system should be considered in the management of firearms. , That is, taking guns and returning guns are in units of platoons, and each company platoon leader is issued an identification card, which is shown when taking the gun or returning the gun, and the card number is recorded into the system, and the card is taken away or returned Of firearms and equipment 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 identity registration and identification, personnel can enter the firearms depot. During the process of taking out the gun, the system will automatically scan and identify the firearms and equipment when they take the gun 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 authorization 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 manager selects the type of reason or enters the remarks, 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 incorrectly fetching 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 in a large range;
• Activator: used to collect tag information at close range.
• 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, 2.45G combined with 125K dual frequency;
• In view of 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 cord.
• For bullets, the label can be packaged on the bullet bag or pasted on the magazine.
The activator plays a pivotal role in the RFID system. The frequency of the activator determines the working frequency band of the radio frequency identification system, and the power of the reader directly affects the distance of the radio frequency identification. 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 1 to 5 meters. The activator is installed at the door of each gun warehouse, and when the gun enters and exits the door, it is activated by the gun wearing tag, so as to manage the time the gun enters and exits the warehouse.
The selection principle of the activator is as follows:
• High reading rate, high stability;
• The radio frequency module and control software part of the reader have a high degree of consistency;
• Comply with multiple protocols and can read multiple types of tags;
• The reader software can be smoothly upgraded according to the development of multiple standards such as EPC;
• With rich interfaces;
• Able to realize simultaneous reading of multiple tags in the read-write area, with anti-collision function;
• Check the error information in the process of reading and writing;
• Support TCP/IP protocol, easy to configure and manage through the network.
• The current of the matching antenna coil is large enough;
• Antenna power matching;
• The antenna has sufficient bandwidth to ensure the transmission of carrier signals.
Base station antenna reader
According to the requirements described by the user, choose a high-performance four-port module from a professional RFID product manufacturer in the United States. The antenna reader of this design conforms to EPC class 0, class 0+, class 1, class 1 Gen 2, ISO18000-6A/B , EM multiple protocols, can read and write multiple tags that comply with these protocols. This reader can be upgraded through the network to ensure that it meets the needs of users to replace tags with different protocols in the future.
The RW-R801 reader is equipped with 2 spherical polarized antennas, so users do not need to purchase matching antennas.
