RFID system composition and application in warehousing
From all aspects of feed product logistics and warehousing management, it can be seen that due to the factors of large packaging volume and weight of feed products, as well as the characteristics of perishability, it is determined that warehouse management, item turnover and data management are more difficult. To this end, this paper builds an identification system based on RFID technology to improve the processing efficiency and accuracy of inventory commodity data.
1 Composition of RFID system
The RFID system consists of a background control center, a LAN server, an antenna sensor, a radio frequency reader and an electronic tag.
First of all, in the warehousing link of the commodity, an electronic tag is installed on each packaged feed commodity, including the name of the commodity, the quantity of packaging, the quality, the warehousing time and other information. The electronic tag has a built-in chip, antenna sensor and battery, where the chip is used to store information about feed products, and the antenna sensor is responsible for sending and receiving signals and transmitting information. When using a reader to find an electronic tag, the antenna receives radio wave information and transmits the relevant information inside the electronic tag to the warehouse manager. Electronic tags occupy an important position in the RFID system and determine the performance of the entire RFID system. The performance of the entire information reading system can be improved by upgrading the chip with stronger performance and the antenna sensor with higher sensitivity.
Secondly, the RF reader is mainly used to write and read the relevant data inside the electronic tag, the video reader can find the location of the target tag, and can also write and retrieve the inventory commodity data at any time, and the reader also has a built-in chip and a wireless signal sensor, which is responsible for data interaction with the control center and the electronic tag.
Third. The control center is a set of back-end data management system, which includes the host, RFID system software and database. Based on local area network. On the one hand, when the librarian operates the reader. The control center software system can update the data in real time, so that the data entry is accurate and the original inventory data is accurate. The RFID system can automatically realize the daily clearing and monthly settlement of inventory data. The RFID system can be used according to the user's request. To produce different types of inventory reports, only the administrator has the right to modify the system functions and core data, and others have no right to modify them, so as to ensure the traceability of records.
At last. The LAN server is the premise of realizing the connection and stable operation of each module, and the library management personnel need to test whether the network and each module are available before each operating system. If the network is disconnected, data may not be uploaded, which will affect the security and accuracy of the data.
2 Application of RFID technology in the storage of feed products
The workflow of the RFID system is relatively simple and efficient, easy to operate and use. The warehouse center administrator must be able to use the whole module proficiently, the performance is limited, and the stability is insufficient. In addition, the entire RFID system, and can judge whether the system performance, network connection is normal, whether it covers all the electronic tags and tag power can maintain normal operation. Using RFID radio frequency reader and inputting relevant instructions, the signal is transmitted to the target electronic tag through the network. After the signal command is received by the corresponding tag, the chip automatically enters the response state, the built-in data begins to update and modify, and the signal after the data update is fed back to the operator. The RFID RF reader decodes the signal based on the LAN and transmits the information to the control center, and the background control center completes the data update, processing and storage. The control center of the RFID system usually has powerful data analysis and processing functions, and can output various different types of feed product data reports or charts according to the user's command messages. The control center of the RFID system also has an automatic error correction function when there are data inconsistencies or contradictions. It can warn the operator. The control center system software design of the RFID system should have good compatibility and scalability, so as to meet the requirements of subsequent auxiliary function upgrades and database expansion.
