RFID Technical Introduction

● What is a RFID?
RFID is an abbreviation for Radio Frequency Identification, or RFID, commonly known as electronic labels.

● What is the RFID technology?
RFID RF identification is a contactless automatic identification technology that automatically recognizes target objects and obtains relevant data through RF signals. The identification work is done without manual intervention and can work in a variety of harsh environments.RFID technology can recognize high-speed moving objects and can identify multiple labels simultaneously, fast and convenient to operate.
RFID is a simple wireless system with only two basic devices used to control, detect, and track objects.The system consists of an interrogator (or reader) and many transponders (or tags).

The basic component of the RFID

Overall design idea of the system
● electronic Tray management based on RFID
●After the development of  Industry No.1 project and the subsequent code typing project, a major bottleneck in the logistics operation of industrial warehouse code scanning enterprises.The implementation of RFID electronic tray management method can alleviate the bottleneck of industrial exit code scanning.We will support the industrial and commercial integrated transportation of finished cigarettes in the industry.

● is electronic location management based on RFID
●With the continuous development of tobacco logistics, as well as the development of industry No.1 project, code to bar and other projects, the requirements for logistics lean management are increasingly prominent, and the key in the logistics link, how to conduct more accurate and effective management of the location of goods, has naturally become the urgent requirement of tobacco circulation enterprises.
●with the application of RFID technology in the tobacco industry, cargo management can also be applied this new technology, based on RFID electronic cargo management can realize cigarette warehousing link tray up and down check, and electronic inventory function, not only convenient for the precise management of inventory, and improve the accuracy of warehousing operations.
●At the same time, the application of electronic cargo location management has also played a great auxiliary role in the management of the storage operation process. It can accurately record the operation information such as the starting and ending time of the operation process of each link, realize fine and trace management, and prepare for performance assessment.

Job operating system in the RFID library
●The project requires a WMS(digital storage management) system, so the operation operating system in the RFID library is a middleware between the background WMS system and the front-end hardware equipment.The WMS system completes the data exchange with the front-end hardware equipment through the operation operating system in the RFID library.

●The operation operating system in the RFID library contains functional modules of data communication, business logic, equipment control, data compression and data storage.Each functional module works in collaboration with the hardware equipment to complete the operation instructions issued by the WMS system.
