Description

Equipment and method for applying radio frequency identification technology to superscripting operations

technical field

The present invention relates to a device and method for applying radio frequency identification technology to labeling operations, especially to a device that provides RFID label function verification and database connection operations, the detection of the best position of RFID labels on objects, and the application of RFID labels. Completed function reconfirmation and other operations - a complete RFID label labeling solution.

Background technique

Radio Frequency IDentification (RFID) mainly includes RFID tags (Tag), RFID readers and application systems. Among them, the operating frequencies used by RFID include low frequency (LoW Frequency, usually 134KHz), high frequency (High Frequency, usually 13.56MHz), ultra-high frequency (Ultra-High Frequency, usually 860~960MHz), and microwave ( Microwave, usually 2.4GHz), etc. Passive (Passive) RFID tags do not contain batteries, and their internal analog circuits convert electromagnetic waves from the reader into electrical energy for use. There is a memory body in the RFID tag to store data. According to the design and manufacturing process, it can be divided into read-only, single-write multiple-read, or repeatable read-write and other styles. Because the RFID identification system uses electromagnetic waves to transmit energy and signals, RFID tags are easily affected by the material properties of the pasted objects, the surrounding magnetic strips or metal materials; the materials of the pasted objects will affect the frequency response of the RFID tag antenna, while the surrounding Magnetic strips or metal materials will affect the reading effect due to the size of the area or volume, and the interference phenomenon (Interference Phenomenon) caused by the distance. Because the electromagnetic waves in the frequency range used by the RFID identification system are invisible, the constructive or destructive interference (Constructive or Destructive Interference) caused by the influence of the surrounding magnetic strips or metal materials cannot be predicted; in the past, radio frequency identification was used When the system is applied, it takes a lot of time and repeated pre-labeling operations to attach passive RFID tags. Usually, different positions are tested on the object to be pasted first, and then the reading rate is checked with a reader; it is time-consuming to find out a relatively suitable position for pasting, and it is often difficult to find the proper position.

The well-known method in the past is to use the strength of the read RFID tag signal (such as received signal strength display, RSSI, Received Signal Strength Indication) to judge the quality of the RFID tag. When the signal is found to be weak and the effect is not good, it is judged that the quality of the RFID tag is poor . Another usage is to test the reading effect of the RFID tag that has been pasted on the object. When the detected signal is weak or the reading rate is not good, it can only be judged that the current position or placement method is not appropriate. However, RFID tags are not resistant to repeated sticking and tearing actions, and repeated sticking will easily make the adhesive layer insufficient, and repeated tearing off will easily damage the RFID label, which invisibly causes waste of manpower, time and resources.

Contents of the invention

In order to solve the above problems, the present invention provides RFID tag function verification and database connection operations, RFID tag on the object best pasting position detection, RFID tag pasting completed function reconfirmation and other operations - complete RFID tag superscripting solution plan.

In the superscripting operation, it is necessary to connect the object information with the RFID tag. The object information can be connected to the database of the host computer using a digital communication interface, or the relevant data can be stored in a memory card (such as SD, CF, XD memory card, USB portable disk, etc.) into the database. If the object has been pasted with a barcode, you can use the built-in barcode reader or an external barcode reader to read the barcode, select the relevant data from the external or internal database, and use the built-in RFID reader according to the predetermined coding principle ( Have the function of reading and writing RFID tags) write to the EPC storage area of RFID tags or related writable storage areas, and connect to the database; or only do RFID UID and database connection processing according to the type of tags and application requirements. After the RFID tag has undergone the aforementioned operations, it is also possible to first verify whether the basic functions of the tag can be used normally?

When preparing to affix RFID tags on objects, place the objects and RFID tags on the RFID tag reading window area where the size can be flexibly adjusted on the radio frequency identification labeling operation equipment box, and first use the RFID reader to detect the signal strength and read rate. RFID tags can be moved horizontally before pasting, and the system will automatically display the detected signal strength and read rate information on the display on the device (such as liquid crystal display, cathode ray tube, etc.), or an external display. At the same time, according to the pre-set pass and fail grade specifications, different color lights will be used to display, and appropriate prompts can be provided with the audio device to speed up the determination of the appropriate position of the RFID tag.

After the RFID tag is pasted on the object, use the radio frequency identification labeling operation equipment to detect the RFID label signal and read rate again to confirm that the labeling operation is completed correctly. Because each individual object will have some differences in the production or processing process; especially if there are magnetic strips that are randomly pasted in the book, the differences in the number of pages at intervals, height, length or thickness are greater; through this The invented equipment and method can ensure that each individual object can get the best pasting position, and give full play to the performance of RFID in application. The relevant RFID tag signal and reading rate data can be archived or imported into the test database for subsequent optimization analysis and control.

The invention provides a method for applying radio frequency identification technology to superscripting operations, including:

Using a radio frequency identification superscripting operation equipment to conduct a data access test of an RFID tag;

Data connection between the RFID tag and an object; relative position detection between the RFID tag and the object; and

The RFID tag is pasted on the object and the labeling completes the test operation.

The present invention also provides equipment for applying radio frequency identification technology to superscripting operations, including:

A metal box to avoid external electromagnetic interference, and at least one RFID tag reading window on it to transmit electromagnetic waves for RFID tag testing;

An antenna, installed in the metal box, is used to detect the relevant functional characteristics of the RFID tag in the labeling operation;

At least one digital interface is erected on the metal box to transmit data or store data;

At least one button or switch is erected on the surface of the metal box to perform related operation control; and
