UHF RFID hardware application helps enterprise asset management realize intelligent upgrade

　　Fixed asset management is an important part of enterprise management. Many enterprises encounter problems such as untimely information reflection, time-consuming and labor-consuming, asymmetry of information, and confusion in inventory management in the management of fixed assets. The use of UHF RFID technology combined with a back-end database system can realize the intelligent management of fixed assets.

　　In the asset management project, the application of UHF RFID hardware can realize the upgrade of its management intelligence. The handheld reader is used for asset inventory. It can quickly read the electronic tag information on the device and transfer the read tag information through the built-in The communication method is sent to the background server for processing. The fixed reader is used for access control, and the antenna adopts a circularly polarized antenna, which can ensure multi-angle tag recognition. After the completion of the whole life cycle management of new addition, allocation, inventory, idle, maintenance, and scrapping of assets, automatic asset management is realized.

　　Then, in the application of asset management projects, what products do UHF RFID hardware mainly include? What are the specific characteristics and advantages? How to choose?

　　1, RFID electronic tags

　　UHF RFID technology is mainly affected by metal and liquid, so it is always difficult to cooperate with metal products or metal environments, which makes the management of metal items through RFID technology face severe challenges. Some of the anti-metal electronic tags on the market generally have a series of application problems such as large size, short reading distance, unstable performance, and difficult installation. In general asset management projects, asset items with metal attributes occupy the majority, and there are various sizes and types, so specially designed RFID anti-metal tags are required. Broadwin Smart has specially designed various sizes of anti-metal tags for metal and other complex environments. They have the characteristics of long reading distance, high sensitivity, easy installation, and excellent physical characteristics. The use effect is very ideal in the application of asset equipment management.

　　2, RFID antenna

　　The selection of RFID antenna mainly considers the polarization direction, antenna gain, beam angle, working frequency, mechanical size, application environment, etc. In order to ensure that the tag can be read at random rotation, we use a circular polarization antenna, which is in good condition with the coaxial cable. Matching and good directionality, small size, easy to install. Then confirm the location and quantity of the antenna installation according to the site environment. Because RFID recognition is restricted in the metal environment, the directivity and installation location of the RFID antenna are very important. It usually takes repeated tests on site to find the best angle and obtain the best recognition effect.

　　3, fixed reader

　　The asset management RFID system mainly uses fixed readers to automatically complete data collection, and handheld readers are used as an auxiliary means of asset inventory. The fixed reader/writer independently developed and designed by Broadway Intelligence is a supporting ISO18000-6C protocol, the working frequency range is 902MHz～928MHz, the output power is 0dBm～33dBm optional, and it has long recognition distance, fast speed and super multi-tag recognition ability. High-end RFID reading and writing equipment with strong, strong anti-interference ability, high protection performance and easy installation and use. The reader's tag reading distance is set at about 2 meters, and the reading rate reaches 400 tags/sec, which quickly completes data collection.

　　4, RFID handheld terminal

　　When staff count assets, they only need to hold an RFID handheld terminal to read the RFID electronic tag information on the asset, and at the same time, pass the read information to the server through the communication interface, and the server will then perform processing on the information through the application software. Deal with it accordingly. If there is a conflict between the scanned data and the existing data in the database, an alarm will be generated, and the inventory operation will be completed after the check is correct. RFID handheld terminal integrates powerful UHF read and write functions. Compared with traditional reading methods, it has better sensitivity, which helps to achieve more accurate and faster data collection.

　　5, RFID channel access control

　　Set up RFID access control at the entrance and exit of assets. When assets enter and exit the access control, the access control will automatically identify the asset with the electronic tag, read its related information, and upload the information to the background server. If the asset is moved without authorization, it is an illegal tag, and the access control will give an alarm. Similarly, when the asset arrives at the destination, it is read by its door, and the system will update the asset information. The ultra-high frequency access control system independently developed and designed by Broadway Intelligent supports EPC C1 G2 (ISO18000-6C) protocol, supports server mode to achieve multi-channel control function, internal integration of high-gain antenna group, high-speed reader and control module based on ImpinjR2000 , With high-speed tag reading performance and good read-write area control capabilities, it provides a standard RS232 or RJ45 interface for easy connection to the software platform.

　　application effect

　　1. Improve inventory speed: RFID handheld terminal quickly inventory, increase inventory speed by more than 10 times, and automatically generate inventory report.

　　2. Improve the search speed: RFID search for fixed assets, enter the number to search, find in 3 minutes, and increase the efficiency by 50%.

　　3. Full life cycle management: RFID completes the full life cycle management process of asset addition, allocation, idleness, inventory, maintenance, and scrap.

　　4. Improve management efficiency and reduce error rate: Through the RFID asset management system, automatic asset management is realized, management efficiency is increased by 50%, and the expected application effect is achieved within a certain range.
