γγChina is becoming a global manufacturing center and a world factory. No matter in which industry, the informatization of procurement, storage, manufacturing, packaging, loading and unloading, transportation, circulation processing, distribution, sales to service and other links has become our urgent need. solved problem. The informatization construction of the tobacco industry has also been included in the national 863 plan. At the same time, the application of radio frequency identification technology in the tobacco industry of Zhejiang China Tobacco Industry Co., Ltd. has been included in the first batch of national informatization pilots. The State Tobacco Administration established the “Project No. 1” project. The No. 1 Tobacco Project refers to the tobacco industry’s cigarette production and management decision-making management system. It is the largest information project in the tobacco industry in recent years. Large-scale wide-area network management platforms across the country. At present, the promotion of the first phase of the “No. 1 Project” in the tobacco industry has already been completed, and the second phase of the work has been carried out nationwide. In the design and implementation of the project, some urgent problems have gradually emerged. First, the unified management of cigarette information across the country is an extremely large and tedious task. In addition to the need to track cigarette information, it also needs to confirm information in multiple links, which greatly reduces work efficiency; secondly, , The traditional bar code is easy to deface. The need for precise alignment requires high environmental conditions and cannot meet the demand for popularization. Thirdly, there are also inconsistencies in the way of shipping. The ways of shipping cigarettes and pallets are different, which makes some manufacturers The data cannot be collected effectively, and the full transparency and effective management of tobacco logistics cannot be truly realized. After the argumentation of many experts and scholars, the RFID solution can solve these problems very well. Due to its inherent powerful management functions, the RFID solution can meet the requirements of the “one-warehouse” distribution operation mode of “modern logistics”. It is suitable for large-scale and busy logistics and distribution. It can ensure high-quality data exchange in the supply chain and can provide cigarettes for the industry. Production and operation provide a basis for decision-making and meet the requirements of the No. 1 project of tobacco industry informatization. At the same time, by thoroughly implementing the “source” tracking solution and increasing its transparency in the supply chain, extracorporeal circulation can be effectively curbed or even eliminated, and it can play a huge role in tobacco monopoly management. At present, the application of RFID in the tobacco industry is better than other industries, and its usage is greater. It has become a bright spot in China’s tobacco industry.
two.Introduction to the production and sales process of cigarettes
The tobacco industry includes two types of tobacco industrial enterprises and commercial enterprises. Industrial enterprises are mainly responsible for the production of cigarettes, and commercial enterprises are mainly responsible for the marketing of cigarettes. This is mainly for the realization of a tobacco monopoly system. The production and sales processes of industrial enterprises and commercial enterprises are as follows:
Industrial Enterprises:
Commercial Enterprise:
three.The application mode of Yuanwanggu RFID products in the tobacco industry
In view of the actual situation of tobacco industry and commerce enterprises, we use RFID system to insert into the process of cigarette production and sales, which greatly improves the efficiency of cigarette storage and logistics, and makes a considerable contribution to the information construction of the tobacco industry. Let’s take the application of RFID products in industrial enterprises as an example (the application models in commercial enterprises are similar to each other) to introduce:
RFID application mainly includes four parts: palletizing (association of pallet cigarette information), pallet adjustment (update of pallet cigarette information), pallet scanning (using pallet cigarette information), and pallet removal (relational information removal).
Electronic label detection
In order to ensure the availability of electronic tags when entering the palletizing process and minimize the error rate of the palletizing process, it is necessary to check the availability of electronic tags before using electronic tags for palletizing, and remove electronic tags that cannot be read and written normally. To ensure that the electronic tags that can be used normally are installed in the tray to enter the circulation link.
Pallet cigarette bar code collection
In the link of cigarette warehousing, the 32-bit barcode on the cigarette is collected by a fixed scanner or a handheld scanner, and the barcode group information of each cigarette corresponding to each stack is obtained after a certain logical processing by the control system. In the system Save it for later use when you need to use the cigarette barcode group for operations.
Stack information writing
After the stacking of cigarettes is completed, the operation of writing electronic tags is required, that is, stacking information writing. By scanning any cigarette barcode on the tray, the corresponding barcode packet data is obtained from the barcode packet database, and the RFID device is controlled to compress the barcode packet data into the electronic label, and the writing result is displayed by the signal light.
Duo information adjustment
In the warehousing link, due to objective conditions such as possible damage to the cigarettes on the pallet, artificial replacement, etc., it is necessary to correct the electronic label data when the specific cigarettes on the pallet change, so as to ensure that the electronic label data in the pallet is consistent with that on the pallet. The barcode data of the specific inspection corresponds correctly.
The specific operation steps are: collect the barcode data A of the cigarette to be adjusted through the one-dimensional barcode scanner, and collect the data B stored in the stack tray that needs to be adjusted through the electronic tag reading and writing device (the correct corresponding data of the cigarette barcode before adjustment) , And then decrypt and analyze the data of B to form a stack bar code data group C, and compare and adjust it with C according to the adjusted functions of A (adjustment, decrease, and replacement) to obtain the adjusted stack bar code data group D, and perform data on D The data E is obtained by compression, and then the data E (correct corresponding data with the latest cigarette barcode on the pallet) is written into the electronic label installed on the stack pallet through the RFID reading and writing device.
Factory scan by stack
When the entire pallet of cigarettes needs to be scanned in and out of the warehouse, the RFID read-write device is used to read the data of the electronic tag on the pallet, and the corresponding barcode information of the cigarette is obtained through decryption and analysis, which meets the needs of the scanning system to collect the barcode information of the cigarette, ensuring one The normal collection of cigarette bar code data by the number project and the code-to-bar system.
Scanning process by stack
After the receipt is issued, RFID read-write equipment is allocated to the document to make it work, and the data of the electronic tag can be read when the electronic tag passes through the identification area of ββthe RFID read-write equipment;
If the data in the electronic label is read, the data can be decrypted and analyzed normally, and then the barcode data combination after decryption and analysis will be checked for legality. If it is legal, save the barcode information and use sound and light to indicate success; if it is illegal, Use sound and light to alarm to indicate unsuccessful;
4. Product list:
The application of RFID in the tobacco industry originated from the “No. 1 Project”. On the basis of this successful application, a series of new application modes have been gradually developed.
Five, system advantages
This solution adopts passive electronic tags, with long life, maintenance-free, unique design, and can be well embedded in plastic pallets, and it is not easy to be impacted and worn during the transportation of the pallet. In addition, electronic tags can be repeatedly written into data, which is helpful to solve the warehousing and logistics problems of pallet cargo adjustment and assembly. The tags can be recycled, which greatly saves users’ costs.
The system realizes long-distance recognition, fast and reliable reading and writing, can adapt to dynamic reading such as conveyor belt operation, and adapts to cigarette production plants and other industrial production environments (stacking of cigarettes), has good anti-metal interference ability, and can overcome cigarette metal The influence of foil packaging on RFID identification meets the needs of modern logistics.
Advanced data compression technology is used in the label information processing, so that the electronic label carries the pallet load information (data packet), and only needs to scan the pallet electronic label once to understand the item information, eliminating the manpower required for disassembling and reinstalling the pallet Material resources, save time, reduce the error rate and the probability of damage to goods, realize fast and accurate inventory counting, and improve the overall transparency of enterprise logistics.
Six, system implementation benefits
This solution uses long-distance RFID technology, which greatly improves the speed and accuracy of code scanning in and out of the warehouse, improves the efficiency of logistics operations, and solves the problems of rising labor costs and difficulties in on-site control caused by pallet removal and pallet loading. The successful application of the system in the logistics link has summarized the experience, laid the foundation and established a model for the application of RFID technology in the logistics field of the tobacco industry.
