In file management, how to select RFID equipment correctly?

　　The RFID data acquisition system includes a reader, reader antenna and electronic tag. In file management, the electronic tag is bound to the file box or file bag, and the signal is transmitted to the system through the antenna and reader to form Automated data collection work. These three together determine the actual effect of the RFID system. Choosing different RFID devices will have a great impact on the actual application effect of the entire project. In RFID projects, string reading, misreading, and low recognition rate are the most common problems, and users The most troublesome problem, these problems are actually solved by choosing the right RFID equipment. Then take RFID archive file management as a case to analyze how to select RFID equipment correctly.

　　About RFID electronic tag selection

　　In archival file management, it is usually necessary to identify how many files there are in a cabinet, or to be accurate to how many files there are on each layer. The thickness of the file bag is basically inconsistent, and some files are very thin when there is less paper. Maybe the thickness is only 1-2MM. In this case, we have to choose labels with good stacking performance. When the two labels of ordinary labels are close, the performance will become very poor. It is due to the coupling between the label antennas that the label frequency band occurs huge change.

　　About RFID antenna selection

　　Speaking of UHF reader antennas, we often don’t know how to choose antennas in project applications. The most important points in choosing antennas are: polarization direction, antenna gain, beam angle, working frequency band, mechanical size, and application environment Wait. In file management, we need to choose an antenna with a very uniform field distribution. Many users think that the file and reader antenna are very close and should be identified by the near-field antenna. In fact, this is not the case, and the far-field antenna should be selected as the near-field. Use, because in many file management projects, the antenna is installed inside or under the cabinet, and the recognition distance is required to be about 15-30CM. Under the maximum power of the reader, the recognition distance of the ordinary near-field antenna may be as long as 30CM. Under the condition that the label performance is very good, there is no margin in use, and there is not enough energy to supplement the energy lost in the accumulation of the label.

　　About RFID reader selection

　　After determining the tag and reader antenna in the RFID file management, the choice of reader is relatively fixed. First consider the issue of operating frequency. The tag and antenna used in the front are UHF, so the reader should also choose UHF. Secondly, we must consider what size antenna to install on the fixed reader and the number of antennas installed. Generally, the fixed reader has multiple antenna interfaces for installing external antennas, which are divided into four-channel reader and eight-channel reader Etc., readers with different forms of antennas can be used universally. In addition, the fixed reader is connected with the input and output devices, and the function of these devices is to control or accept the control of the reader. For example, when the tag enters the working area of the reader, the electronic eye is turned on and controls the reader to enter the working state.

　　About RFID smart file cabinet selection

　　There are many types of smart file cabinets on the market, and the functions are even more varied. However, the actual application effect is not very satisfactory. If a document file is not stored in accordance with the specified location, the actual location information of the document cannot be queried, but the initial registered location information can only be queried, and the positioning function is useless. It is necessary to choose smart file cabinets combined with RFID technology, and use RFID features such as rapid search and location, rapid inventory, and automatic batch identification to realize real-time monitoring and intelligent management of the entire process of borrowing, returning, searching, and inventory, especially for files that cannot be misplaced. In the case of searching, the RFID smart file cabinet can update the file location information in real time to realize on-site supervision.

　　RFID radio frequency identification technology has the characteristics of non-contact data collection, good data security, fast scanning, large label information capacity, long service life, and reusability. It has unparalleled advantages in file management. It has been widely used in archives, libraries, government and enterprise units, schools, public security agencies and other fields. For enterprises or system integrators considering RFID for file management, the hardware selection step is particularly important. It is recommended to consult a professional RFID hardware company to obtain the best system integration effect.
