1. Introduction
With the increasingly fierce market competition in the circulation field, tobacco circulation companies in various places are prepared for danger, improve their management level, optimize business processes, focus on the management of customer resources, optimize internal and external resources, and ultimately enhance their market competitiveness and increase resilience. In the future a new round of market competition will remain invincible.
At present, the promotion of the first phase of the “No. 1 Project” in the tobacco industry has been basically completed, and the second phase of the work has been carried out across the country one after another. With the deepening of work, some urgent problems have gradually emerged. First of all, it is an extremely large and cumbersome task to uniformly manage cigarette information across the country. In addition to the need to track cigarette information, it also needs to confirm the information in multiple links; secondly, the traditional barcode system has obvious shortcomings , Such as easy contamination, breakage, need to stop waiting for scanning one by one, etc., batch reading efficiency is not high, unable to meet the needs of fast and accurate.
In view of the above problems, we can use RFID technology as a more feasible solution. The digital management system is used to integrate the overall warehouse management, which is the digital warehouse management system of the tobacco commercial enterprise. It can not only meet the requirements of the distribution operation mode in modern logistics, but also be suitable for large-scale busy logistics and distribution, ensuring high-quality data exchange in the supply chain. At the same time, it can improve the transparency of the supply chain through tracking solutions from the enterprise production line. , Can effectively curb or even eliminate extracorporeal circulation, and can play a huge role in tobacco monopoly management.
2. Overall structure
Three, application introduction
1. Introduction to Radio Frequency Identification Technology (RFID)
1.1. Advantages of RFID technology
◆ Convenient and quick to read
◆ Fast recognition speed
◆ Large data capacity
◆ Long service life, wide application range
◆ The label data can be changed dynamically
◆ Better security
◆ Dynamic real-time communication
1.2. Advantages of tray-based digital management
Nowadays, palletization has become an inevitable trend in the logistics of tobacco products. As the basic digital management unit, the pallet is embedded with electronic tags, which will not affect the appearance quality of the goods, but also increase the overall digital average unit number of the goods, which facilitates the realization of accurate digital management of large quantities of goods. The application of electronic tags in logistics distribution centers is based on digital warehouse management application software, computer wireless network technology, and modern logistics three-dimensional high-bay warehouse ideas.
◆ High working efficiency
◆ The damage rate in the logistics process is greatly reduced
◆ Meet the needs of mechanization and automation in the operation process
1.3. RFID forklift application
For the special application environment of tobacco logistics, RFID forklift is the best choice
■ When receiving and dispatching, the antenna can be closer to the position of the tag to improve the reading performance
■ The pallet can be tracked continuously in the whole process instead of discrete tracking
■ With the corresponding warehouse management system, it can realize single-step operation control, eliminate manual intervention, improve operation efficiency, improve and strengthen management, and grasp detailed inventory and distribution in real time
2. Application process
2.1. Storage
When the goods enter the warehouse through the entrance conveyor belt, the information of each pallet is written into the pallet through the entrance reader and writer, and then the delivery position is calculated through the computer warehouse management information system, and the inventory instruction is sent to the forklift vehicle system through the network system. It is required to be stored in the corresponding cargo space.
2.2. Delivery
The forklift receives the shipping instruction and picks up the pallet from the designated cargo location. Forklift the front forklift reader to reconfirm the accuracy of the pallet goods, and then send the pallet goods to the conveyor belt at the outbound port, and the conveyor belt reader at the outbound port reads whether the pallet label information is accurate and verifies that the shipment is correct.
Four, application system
1. System hardware
◆ RFID tag
◆ Fixed reading and writing equipment
Used in automated stackers, conveyors, hoists
The RFID reader transfers the read tray information to the PLC for corresponding processing
◆ Handheld reading and writing equipment
For manual stacking
First read the tray information, and then read the barcode information on each stack of cigarettes one by one, upload the information to the system, and associate it in the database
◆ RFID Forklift
For restacking
Read the tray information through the RFID reader, and then use the wireless scanner to scan the barcodes on the removed or added cigarettes one by one, upload all the data to the system, and update the database
2. System Software
◆ Receiving management system
◆ Warehouse business management system
◆ Pallet warehouse management system
◆ Interface service middleware
