RFID Application of warehousing logistics manageme

RFID Application of warehouse logistics management in manufacturing enterprises

in view of the current situation of national tobacco management, the relevant competent departments have implemented the "industry cigarette production and operation decision-making management system project" throughout the country, using automatic identification technology such as bar code to grasp the national production and operation information in real time. However, the previous logistics link of a cigarette factory has been the transportation of "pieces of cigarettes in stacks". How to meet the data statistical requirements of relevant departments and solve the interaction and unification of logistics and information flow of stacks of cigarettes has become the core of technological transformation on the premise of maintaining the original enterprise management system as far as possible. The project successfully combines bar code identification and radio frequency identification, providing a vivid application case for the informatization of the tobacco industry

the industry cigarette production and management decision-making management system project is of great significance and impact on China's tobacco industry. After the implementation of the system, the competent departments will be able to understand the production situation of various cigarette factories in the country more quickly, clearly and transparently. Previously, the competent departments' information acquisition was mainly achieved by manually entering the summarized statistical annual report and express report, and there were some deficiencies in the timeliness, accuracy and supervision of information acquisition. After the implementation of the system, the purchase, production and sales of tobacco enterprises are all transparent. Through the non landing collection of information, the competent departments can grasp the national production and operation information in real time, so that the national cigarette production and operation can be more effectively macro-control

the industry cigarette production and operation decision management system requires that each cigarette produced should be pasted with the barcode issued by the competent department, and scanned for outbound sales. However, the previous logistics link of a cigarette factory has been the transportation of cigarettes in stacks (50 cigarettes per box and 30 cigarettes per stack), as shown in Figure 1. If the cigarettes in stacks are disassembled and scanned in the logistics link, it will not only take time and effort, And often cause damage to finished products. Therefore, from the perspective of tracking the world's advanced automatic identification technology, combined with the actual situation of the logistics turnover of finished cigarette pallets in a cigarette factory, the competent department proposed the method of using RFID electronic tags in pallets transported in stacks. Through the combination of bar code and RFID electronic tags, the problem of interaction and unification of logistics and information flow of stacks of cigarettes was solved

the outbound and arrival scanning system by stack is an RFID scheme for the outbound and arrival scanning links of tobacco enterprises, which take the stack as the unit. In order to realize the data requirements put forward by the industry cigarette production and operation decision management system

adopt RFID technology to identify stacks of cigarettes, store the barcode information of cigarettes in stacks, and use the readable and writable function of RFID to combine the barcode with RFID electronic tag to realize the factory scanning of cigarette factories in stacks and the commercial arrival scanning of cigarette circulation enterprises in stacks. Simplifying the operation process, improving work efficiency and reducing the labor intensity of workers are the main goals of this technological transformation

composition of system design

according to the actual situation of a cigarette factory and a cigarette circulation enterprise (hereinafter referred to as "a municipal company"), the system is designed with four parts: stacking data generation, writing electronic labels, warehouse cigarette information data adjustment, ex factory scanning by pallet and arrival scanning by municipal company

operation process of the system

first, stacking data generation. In the palletizing process, the fixed scanner is used to collect the barcode information of each stack, and after compressing these barcode data groups, the compressed information is written into the electronic tag installed on the stack tray through the electronic tag reading and writing equipment

secondly, stack data adjustment. In the storage link, the barcode data a of cigarette pieces to be adjusted by the barcode acquisition equipment is collected and adjusted by the mobile electronic label reading and writing equipment. The barcode data stack thickness or steel B with a diameter greater than 60mm stored in the stack tray is adjusted, and then the data of B is decompressed to form the stack barcode data group C. the stack barcode data group D is obtained by comparing and adjusting with C according to the functions adjusted by a (increase, decrease, replacement), D is compressed to obtain e, and then E is written into the electronic tag installed on the stack tray through the mobile electronic tag reading and writing equipment

third, scan by stack. When leaving the factory, the RFID reader is used to read out the barcode data of cigarettes stored on the electronic labels on the pallets, decompress the data, and finally realize the docking with the factory scanning system of one dozen and two sweeps (that is, the barcode uniformly issued by the competent department for the printing and pasting of each cigarette produced, and the outbound scanning and the warehousing scanning of the sales enterprise)

finally, scan by stack. At the time of commercial arrival, RFID is used to read out the barcode data of cigarettes stored on the electronic labels on the pallets, decompress the data, and finally realize the docking with the one dozen two scan commercial arrival scanning system

application equipment

rfid electronic tag

xctf-5013 electronic tag is a special tag designed specifically for the requirements of this project, which can be directly and conveniently installed in the tray, effectively prevent the tag from falling, and facilitate disassembly at the same time

rfid reading and writing equipment

according to the actual situation of the above four links, on the basis of the original xcrf-500w reader writer, we specially designed: xcrf-500w (a) reader writer, which is applied to the palletizing production link to realize the writing function of bar code information in electronic labels; Xcrf-500w (d) reader and writer, together with buried antenna, meet the functional requirements of fast and accurate reading of barcode information in electronic labels in the two links of extremely extensive scanning and arrival scanning in the field of ex factory plastic granulator operation; Xcrf-520w mobile reading and writing device, which is innovated and invented according to the project needs and site conditions, integrates RFID readers, built-in antennas, Bluetooth wireless laser bar code scanners and other devices into a mobile cart that can move freely in the chassis. From the outside of the tray, you can read and write the electronic labels installed in the center of the tray, meeting the complex needs of the storage adjustment process

application effect

using RFID technology can not only meet the requirements of distribution operation mode in modern logistics, but also apply to large-scale busy logistics distribution, ensure high-quality data exchange in the supply chain, and provide decision-making basis for cigarette production and operation in the industry

using RFID technology, a tobacco factory shortened the number of code scanning for a single cigarette from 30 times to 1, which reduced the working links of destacking and stacking, shortened the time, reduced the labor force and cost, and improved the efficiency of logistics and the accuracy of data. At the same time, RFID technology is actually applied in the field of production and logistics to realize the "integrated" management of products from production, storage to sales. By thoroughly implementing the "source" tracking and improving transparency in the supply chain, it can effectively curb or even eliminate extracorporeal circulation. RFID technology has played a huge role in tobacco monopoly management
