Overview of high-frequency readers
The HF reader, as a high-frequency HF RF radio frequency identification device, operates at 13The 56MHz frequency band supports ISO IEC 15693 ISO IEC 18000-3 M1 protocol, transmits energy through the inductive coupling of the antenna coil, and activates the electronic tag to realize the automatic identification of the electronic tag. This magnetic field signal has a clear reading area boundary to ensure the accuracy and security of information, and is widely used in the identification of people or items within 1 meter. Its power range is 0Between 5W and 5W, it can be flexibly adjusted by software according to the actual application requirements. In addition, the high-frequency reader is divided into a built-in antenna reader and a split reader, and the split reader provides up to 1 to 36 antenna interface options to meet the diversified needs of different scenarios.
High-frequency reader features:
The characteristics of high-frequency readers are diverse. First of all, it works at 13The frequency band of 56MHz, which has a wavelength of about 22 meters, and its telecoupling protocols ISO IEC 15693 and ISO IEC 18000-3 M1 ensure stable and efficient communication. Second, RF signals in this band are able to penetrate most materials except metallic materials, allowing the reader to maintain excellent performance in a variety of environments. In addition, the reader antenna needs to be installed at a certain distance from the metal to avoid interference. It is worth mentioning that 13The 56MHz frequency band is widely used all over the world and is not subject to special restrictions, which provides favorable conditions for its popularization in various fields. Electronic tags have various forms, can write information, and can be made into PVC cards, self-adhesive labels, anti-metal labels, high-temperature resistant labels and other forms.
Common applications for high-frequency readers
Library and archival management: The synergy between the high-frequency HR7748 reader, the high-frequency HA1026 antenna and the electronic tag has played a huge role. Together, they realize the rapid borrowing and return of books, and improve the efficiency and accuracy of book inventory, sorting, and loading and unloading shelves. With the rapid development of new book management methods such as smart bookshelves and book sharing cabinets, the application of high-frequency readers and high-frequency HA2621 book antennas is becoming more and more extensive. They can identify the book information inside the smart bookcase in real time, realize the miniaturized and distributed management of the library, and greatly facilitate the borrowing of books and the analysis of readers' reading preferences.
Pharmaceutical consumables managementThe high-frequency HR7758 reader combines the high-frequency HA1026 antenna developed according to the intelligent consumables drug consumables cabinet, and realizes the real-time monitoring and inventory management of pharmaceutical consumables by reading the electronic tag information on the pharmaceutical consumables. This system can grasp the inventory of each drug consumables cabinet in real time, which is convenient for the allocation of drug consumables in the background, making inventory easier and faster. At the same time, by monitoring the inventory situation in real time, it can also effectively avoid medical accidents caused by out-of-stocks.
Tube reagent management: The application of the HF HR7768 reader and the HF HA1026 antenna also plays an important role. They can quickly identify the electronic tags on the test tubes and reagents, ensuring that the storage of reagent tubes in the laboratory is always under strict supervision. This not only improves the safety of reagent management, but also improves the efficiency of reagent management through the information management of usage records.
Blood and biological sample management: The RFID high-frequency reader HR7738 is installed in the blood bag and biospecimen cabinet or transport box to read the electronic tag information on the blood bag and biological sample through the high-frequency antenna, so as to realize the accurate identification and management of these blood bags and biological samples. The life cycle management of the whole process of blood bags and biological samples has been realized.
Intelligent F&B cashier management: A high-frequency HR9216 reader and antenna are installed under the cashier counter of the vending restaurant, and the fast checkout in the catering process is realized by reading the plate embedded with electronic tags. Another application is to install an HR9216 reader and antenna in front of the dish to read the plate information associated with the customer's identity, and combine the dishes to weigh them to achieve settlement by weight.
Meeting sign-in and attendance managementHD2280 sign-in attendance special channel door is deployed at the sign-in attendance point, and the rapid attendance sign-in is realized by reading the electronic tag information in the personnel badge, which improves the efficiency of meeting sign-in and personnel attendance, highlights the high-end of the meeting sign-in and avoids the attendance efficiency caused by the large amount of attendance.
Industrial identificationBy installing HR2878 reader in assembly line or automation occasions, using Modbus or other industrial protocols to connect with PLC or host computer, identify information such as pallets or workpieces, and realize intelligent applications in the industrial field.
In summary, high-frequency readers and their related technologies play an important role in many fields such as library and archives management, pharmaceutical consumables management, test-tube reagent management, and blood and biological sample management. As a leading RFID technology provider in China, Shanghai Yingxin has rich experience and profound technical strength in the R&D and production of high-frequency readers and related products. Its high-frequency reader products have stable and reliable performance and are widely used in various industries. With the continuous progress of technology and the continuous expansion of application scenarios, it is believed that high-frequency readers and their related technologies will show broader application prospects in more fields in the future.
