Chapter 1 System Introduction
1.1 Overview
Due to the extensive management of China’s tobacco industry, the cost of each link is still high, and the cost of the supply chain link is 2 to 3 times higher than that of developed countries. Whether the tobacco industry can closely connect every enterprise, every partner and even every customer in the supply chain, so as to reduce costs more and capture the market faster, is a hot issue in the current informatization construction.
At this stage, the problems that lead to the high cost of the supply chain of domestic tobacco companies mainly include the following aspects:
A lot of manual intervention, low efficiency and high error rate
In order to ensure the continuity and accuracy of the information chain, the investment cost is too high
Real-time monitoring and tracking of goods cannot be achieved
The application of bar codes partially solves the above problems. However, due to the low efficiency of reading and writing, the unchangeable information, and the small amount of information, the barcode is unable to be used in the application of bulk logistics management.
Based on RFID radio frequency automatic identification technology, according to the actual situation and demand in supply chain management, it integrates the existing application and barcode technology of the enterprise, and develops “RFIDSupply Chain Management System”.
This system completely solves the problems existing in supply chain management, breaks the technical bottleneck that restricts the development of enterprises, improves the intelligence of production, the efficiency of warehouse management, the accuracy and throughput of distribution, and realizes the tracking and visual management of the whole process. , to help enterprises reduce operating costs and enhance core competitiveness.
1.2 Introduction of key technologies
1.2.1 RFID Technology
RFID (Radio Frequency Identification) is a technology that uses radio frequency signals for automatic identification of target objects and two-way data communication.
RFID technology is mature and has a good application foundation. Compared with traditional identification methods, it has a strong advantage.
Long-distance reading and writing (1-10 meters)
Multi-target, in-motion recognition (up to 1000/sec)
Large storage capacity, rewritable (100,000 times)
Long service life (50 years)
These characteristics enable RFID technology to complete information reading, writing and processing without direct contact, optical visibility, and manual intervention, and the operation is convenient and fast. It can be widely used in production, logistics, transportation, medical, anti-counterfeiting, tracking, equipment management and other fields that need to collect and process data, and is considered as a future replacement for barcode labels.
A typical RFID system generally consists of RFID tags, readers, and computer systems.
Tag (Tag): composed of coupling elements and chips, each tag has a unique electronic code, which is attached to the object to identify the target object;
Reader (Reader): a device for reading and writing tag information, which can be designed as handheld or fixed;
Middleware (Savant): Connect RFID equipment and application system software.
Chapter 2 Structure of RFID Ingredients Management System
2.1 Overall Architecture

Provide larger storage space to meet the requirements of multiple varieties and large amounts of data;
Using special packaging, waterproof, anti-magnetic, anti-static, anti-collision, to ensure that the label can be used for a long time in harsh environments.
2.3.2 Electronic label reading and writing equipment
This system adopts IMPINJ industrial grade reading and writing equipment, which has the advantages of long reading and writing distance, stable reading and writing, fast reading and writing speed, open interface, strong environmental adaptability, etc. It is suitable for industrial-grade applications.
2.3.3 RFID goods adjustment mobile processing equipment
In order to ensure the continuation of the information chain after the adjustment and reorganization of the goods, it is necessary to re-associate the information of the goods and the pallets and send the data to the background in real time when the goods in stock are adjusted. Web-enabled mobile device.
RFID goods adjustment mobile processing equipment integrates wireless network, barcode scanning, RFID reading and writing functions, simple operation, advanced technology, fully meet the needs of applications, and can work continuously under complex conditions.
