Introduction of asset management system for RFID technology
Radio Frequency Identification Technology (Radio Frequency IdentificatiON, abbreviated RFID), radio frequency identification technology is an automatic identification technology that began to emerge in the 1990s, radio frequency identification technology is a use of radio frequency signals through spatial coupling (alternating magnetic or electromagnetic field) to achieve The technology that contacts information transmission and achieves the purpose of identification through the transmitted information. From the basic principle of information transmission, RFID technology is based on the transformer coupling model (energy transfer and signal transmission between the primary and secondary) in the low frequency band, and based on the spatial coupling model of the radar detection target in the high frequency band (the radar emits electromagnetic wave signals). After hitting the target, carry the target information back to the radar receiver). In 1948, Harry Stockman published “Communications Using Reflected Power”, which laid the theoretical foundation for radio frequency identification technology.
System Overview
RFID radio frequency identification is a non-contact automatic identification technology, which automatically recognizes the target object and obtains relevant data through radio frequency signals. The identification work does not require manual intervention and can work in various harsh environments.Internet of ThingsRFID technology can identify high-speed moving objects and can identify multiple tags at the same time, and the operation is quick and convenient. RFID is a simple wireless system with only two basic components. The system is used to control, detect and track objects. The system consists of an interrogator (or reader) and many transponders (or tags).
The automatic identification and management system of inventory items is a practical management software with the characteristics of physical management and the purpose of simplifying complexity.
The automatic identification and management system of inventory items has used radio frequency technology to solve the problem of the inconsistency between the physical objects and the financial accounts that often occur in the inventory item management, so that the enterprise management is orderly and the accounts are consistent.
The automatic identification management system for inventory items, using efficient data transmission technology, and unique rights management concepts, enables business leaders to understand the overall situation of all inventory items in the company while sitting in the office.
Since its launch on the market, the inventory management system has received unanimous praise from users for its simple method of use and accurate calculation results. It has also been recognized by professionals for its operational safety and technological advancement. The convenient and accurate query function has been appreciated by business leaders.
The long-distance radio frequency identification system realizes the automatic identification of people or objects by collecting the information of the radio frequency card at a long distance and non-contact, so as to realize the automatic management of the target. The system product integrates computer software and hardware, information collection and processing, data transmission, network data communication and smart card production and other technical integrated applications into a high-performance identification technology. It is one of the basic products to realize informatization and automatic management.
The biggest feature of the system is that it can operate independently or be connected with existing asset management. It can use the combination of enterprise LAN and the Internet to build an enterprise asset management information architecture and truly realize the automation and intelligence of enterprise asset management. The system is currently the most advanced, and can provide data collection, offline information reading and writing, offline or online, networked information reading and writing, and information transmission for functions such as global control of corporate assets and global information query and statistical summary.
Introduction and characteristics of inventory management system
system introduction
An item inventory management system for managing inventory data of items, characterized in that the item inventory management system mainly includes: a database for storing a plurality of records, each record includes an identification field, an The serial number field and an attribute field, and these records include at least: (1) An upper-level record used to store data representing an upper-level item, including an upper-level identification stored in the identification field Code, a parent serial number stored in the serial number field, and an upper-level attribute stored in the attribute field are selected from one of the following: inventory, sales, and scattered; (2) a plurality of pens corresponding to the The lower-level record of the upper-level record is used to store data representing multiple lower-level items. The lower-level items can be packaged as a whole to form the upper-level item, and each of the lower-level records includes storage in the identification field The lower-level identification code of, a sub-sequence number stored in the serial number field, and the lower-level attribute stored in the attribute field; and when the upper-level attribute of the upper-level record is inventory, the corresponding lower-level records The lower-level attributes of are the same as inventory; when the upper-level attribute of the upper-level record is sales, the corresponding lower-level attributes of the lower-level records are the same as sales.
System installation steps
Following the principle of “unified card issuance, unified equipment, unified management”, the identification card is regarded as a “post certificate”. The unit in the management center uses the card issuer to associate the electronic label with the person’s name, photo, and other information one by one, and the The corresponding relationship is written into the system database in real time; the system database records the basic information of the person corresponding to the identification card, including name, age, gender, team, type of work, position, photo, validity period, etc.
Labels correspond to items
RFID electronic tags must be installed on each item, through the desktop RFID card issuer, each RFID electronic tag is corresponding to the asset item name, picture, ownership and other information to be managed, and attached to the asset item for unification Management, in this way, the electronic tag becomes the real asset nameplate label, and the information representing the item is thus one-to-one correspondence between the electronic tag and the actual item in the software. In practical applications, the RFID reader will show the actual appearance as soon as the tag is read. Corresponding items.
RFID reader and antenna installation
The most basic RFID system consists of three parts: Tag: consists of coupling elements and chips, each tag has a unique electronic code, attached to the object to identify the target object; Reader: read (sometimes also The device that can write tag information can be designed as a handheld or fixed type; Antenna: Transmit radio frequency signals between the tag and the reader. The basic working principle of RFID technology is not complicated: after the tag enters the magnetic field, it receives the radio frequency signal from the reader, and uses the energy obtained by the induced current to send out the product information stored in the chip (Passive Tag, passive tag or passive tag) , Or actively send a signal of a certain frequency (Active Tag, active tag or active tag); after the reader reads the information and decodes it, it is sent to the central information system for relevant data processing.
Install card readers and antennas on the inside and outside of the warehouse door or on both sides of the door. The antennas illuminate the inside and outside areas of the door respectively. The position of the reader and the height of the antenna are adjustable. , To be suitable for various specific environmental applications, staff wear RFID tags and hang the tags on their chests to enter the gate of the warehouse, and they can be read by the RFID reader and uploaded to the computer system record. When the staff goes out the gate, they are read by RFID The card reader reads that if a worker takes out an item from the warehouse, the RFID tag on the item will also be read by the RFID reader, so that both data are uploaded to the computer system at the same time, and the system will show a certain A person takes an item from the warehouse. Realize accurate, fast and automatic barrier-free inspection of personnel entering and exiting important passages.
Long-distance intelligent identification-the system uses radio frequency identification technology, internal employees and outsiders do not need to swipe their cards, once they pass the warehouse door, the system automatically completes the personal identity security inspection and verification and keeps the inspection records;
Realize item tracking management: The system automatically recognizes and detects passing personnel (cards) and valuable assets (with electronic tags) carried by them at the same time, and realizes the dual functions of item tracking management while realizing personnel management;
Humanized management-internal personnel only need to wear a work card to freely pass through the detection channel, and the system can quickly identify it, without the need for security personnel to judge through their own impressions, and fundamentally eliminate the embarrassing phenomenon of forcing internal personnel to enter the door registration;
Informationized supervision and management-the management personnel of the unit can check the entry and exit records of the gate through the client software,
Using passive radio frequency identification card-(ie, electronic tag) with 100,000 repeated erasing and writing functions, which can be reused for many times;
In line with the development trend of technology-the new international standard radio frequency card technology used in this system adapts to the development trend of domestic and even world RFID radio frequency identification technology;
Expansion and compatibility-wide expansion and upgrade space, compatible with close access control management systems in important areas, unified database management, flexible and convenient multiple search query conditions, to meet the needs of customers’ personalized solutions.
