System Overview
The long-distance radio frequency automatic identification system realizes the contactless information transmission through the spatial coupling through the radio frequency signal and realizes the automatic identification of the articles under different states (moving, static) through the transmitted information, thereby realizing the automatic management of the target.
The system can perform network management according to different management requirements to realize networked application of long-distance radio frequency identification. The system's reading equipment uses ultra-high frequency short-wave frequency (transmitting and receiving frequency 2.45GHz) integrated high frequency (transmitting frequency 125K) to achieve reliable full-duplex wireless data communication.
The electronic tag adopts an embedded microprocessor and realizes functions of sleep, wake-up, decoding, encoding, communication and information collision processing under the control of embedded software. The reading device can simultaneously identify multiple targets; the system can reliably identify 200km/ h fast moving target, recognition distance is not less than 5 meters, no blind zone is identified, no microwave radiation damages the human body, signal diffraction penetration is strong, information security and security performance are high, easy to operate, can adapt to many different Application Environment.
This system is designed for the automation and informationization of military guns and military materials, and is mainly used for the automatic identification and management of military guns.
The system utilizes modern computer technology and RFID technology to realize automatic identification of military firearms, access control management and information management. The system can effectively, accurately and intelligently identify, collect, record, upload and fire information on firearms entering and leaving the warehouse. Maintenance information is quickly queried and counted, thus establishing a digital information management system for military military materials management.
The automatic identification and management system for military firearms mainly consists of three parts: radio frequency automatic identification equipment, 125K in and out of the library equipment, automatic identification of firearms electronic tags, and background management system. The background management system consists of a firearms electronic label issuing management module, a firearms inbound and outbound automatic identification module, a user and user rights 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 enter and exit the warehouse, such as the name of the firearm, the type of firearm, the number of the firearm, the time of entry and exit, the person who passed the hand, the approver, etc.; and master the flow of firearms;
The system will verify the identity and permissions of the recipient. If there is any discrepancy, the system will automatically alarm;
Provide functions such as query, analysis and statistics, and printing to improve the level of information management;
System flow
Due to the special nature of the military, many urgent tasks, and daily maintenance of firearms, etc., the specific conditions vary widely, 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 system of responsibility for the platoon leader. That is, taking the gun and returning the gun in a row, each platoon leader is assigned an identification card, and when the gun is taken or returned, the card number is recorded and recorded in the system, and the card is taken or returned. Firearms equipment is linked to facilitate management. (Note, you don't have to have the platoon leader to attend the game in person each time. You can assign other commanders to handle the card.)
The operation is first logged into the system by the firearms administrator, and this login identity can be used as an “approverâ€.
The commander who performs the restocking operation presents the platoon leader identification card, and the identity information is automatically registered (if the identity is not passed, such as the card expires, etc., the request can be rejected).
After the identity registration is identified, the personnel can enter the gun magazine, and in the process of taking the gun, when the personnel take the gun out of the gun door, the system automatically scans and recognizes the firearm equipment; in the process of the gun, the personnel carry the gun equipment into the gun magazine. When the door is used, the system automatically scans and identifies the firearm equipment. The identified firearms information is associated with the previous personnel identity, and the authority is discriminated, and the correct record is recorded in the database. In addition, in the process of taking the gun, after the system automatically recognizes the firearm equipment, the firearms administrator selects the type of the event or inputs the notes and the like. The information is stored in the database along with the identification information.
According to the information identified by the system scan, if an irregular operation is found, such as mistaking the firearm equipment belonging to other queues, 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 for information collection, processing and transmission. The hardware system consists of electronic tags, antennas, readers, and PCs for information acquisition, identification, and application software.
Electronic tag: attached to the identified object to identify the object.
Antenna: used for transmitting and receiving radio signals on a large scale;
Activator: Used to collect tag information at close range.
PC: Run the application software.
According to the user's needs, in order to achieve accurate reading and prevent cross-talking, we choose passive single-frequency electronic tags.
The working frequency of the tag is UHF band, 2.45G combined with 125K dual band;
For the complex situation of monitoring items, special material packaging is applied to the surface of metal objects.
The label can be pasted as follows:
For machine guns and submachine guns, the label can be packaged on the strap of the gun.
For pistols, the label can be packaged in a pendant or packaged onto a pistol.
For bullets, the label can be packaged onto a bullet pocket or attached to a magazine.
The activator plays an important role in the RFID system. The frequency of the activator determines the working frequency band of the RFID system. The power of the reader directly affects the distance of the RFID. Generally speaking, a high frequency tag has a larger reading distance, but it requires a larger electromagnetic wave energy output from the reader. A high frequency tag can be read at a distance of 1 to 5 meters. The activator is installed in the door of each room of the gun magazine. When the gun is in and out of the door, the tag is activated by the tag, so that the time is in and out of the library.
The selection principle of the activator is as follows:
High reading rate and high stability;
The reader module's RF module and control software are highly consistent;
Compatible 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;
Has a rich interface;
It can realize multi-tag simultaneous reading in the reading and writing area, and has anti-collision function;
Verify error messages during reading and writing;
Supports TCP/IP protocol for easy configuration and management over 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 of the user description, select the high-performance four-port module of the professional RFID product manufacturer in the United States.
This designed antenna reader conforms to EPC class 0, class 0+, class 1, class 1 Gen 2, ISO18000-6A/B, and EM protocols, and can read and write multiple tags that conform to these protocols. This reader can be upgraded over the network to ensure that users will need to change different protocol labels in the future.
The RW-R801 reader is equipped with two ball-type polarized antennas, eliminating the need to purchase additional antennas.
