0 Introduction
Radio Frequency Identification (RFID) technology ****. Radio Frequency Identification, RFID*** also known as electronic tags. Radio Frequency Identification is a communication technology that recognizes specific targets and reads and writes relevant information through radio signals without the need to establish mechanical or optical contact between the recognition system and the specific target.
RFID-based logistics warehousing management using RFID in the data collection, information transfer unique advantages, the realization of the product data information collection of high-speed automation, effectively avoiding manual input errors that may occur. Real-time accurate positioning and tracking can accurately locate the exact position of the product storage, greatly improving the efficiency of the logistics point of stock, warehousing, warehousing, inspection, inventory, replenishment and other work. RFID-based logistics and warehouse management, usually using a combination of software systems and hardware devices to achieve. This paper focuses on how to use the "Internet of Things" ideas to achieve the purpose of intelligent logistics and warehouse management, including the system structure, how to realize the RFID-based logistics and warehouse management in all aspects of the system to solve the problem.
1 system structure
RFID-based logistics warehouse management system architecture shown in Figure 1.
The hardware of this system contains servers, client PCs, handheld devices and RFID tags. In different business segments, all can be used with different software systems.
Designed to combine the abstract "Internet of Things" with physical business processes. "Things" is the Internet of Things perception layer, that is, RFID tags, electronic tags contain physical goods information, through the handheld device can be identified; "United" is the Internet of Things network layer, that is, the regional network or inter-network network, to the various operating sites, the various Network" is the Internet of Things network layer, i.e. regional network or inter-network network, which connects each operation site and each business process; "Network" is the Internet of Things application layer, i.e. the software system, which is capable of realizing the intelligent and informative management of the cargo logistics and warehousing business process. Soft body system contains installed in the client PC on the logistics management client system and warehousing management client system; installed in the handheld device on the handheld system **** including on the signature, warehouse management and point inspection functions ****; and installed on the server integrated information management platform.
2 practical application
2.1 Logistics operation process
Handheld system and logistics management client system *** with the completion of logistics operation process information management, *** with the realization of the original data collection, the initialization of the electronic label, to complete the process of transportation in the process of the several points to confirm the work, as well as the management of logistics information. The main links involved in the logistics set of goods, logistics goods set port, port of departure loading, destination port unloading, logistics delivery of goods and so on.
In the early stage of the logistics operation process can be introduced RFID tags, to carry out some of the initial work, including the collection of original information, the initialization of the electronic tag, on the sign *** will be electronic tags to be affixed to the goods on the ***, etc., will be the electronic tags and the goods to establish a correlation between the relationship, you can carry out intelligent logistics management, including scanning point inspection, cargo identification, cargo query positioning, etc. .
In the logistics operation process generated in the information are stored in the logistics management client system, mainly logistics office personnel to use, to achieve the management of logistics information, is the operation site and integrated information management platform bridge.
2.2 Warehouse operation process
Warehouse operation process is the next link in the logistics operation process, so in the link can be used in the early stage of logistics paste RFID tags, but in the transportation process, it is inevitable that the label falls off or damaged, so in the warehouse should be made up for the signature, has facilitated the later intelligent management, the construction of intelligent warehouse.
Handheld systems and warehouse management client system *** with the completion of the warehouse operation process information management, *** with the realization of the product into the warehouse, out of the warehouse, transfer, inventory and other operations. the application of RFID, so that the goods into the warehouse, out of the warehouse, inventory, goods identification, goods positioning has become very easy to reduce the error of human error, greatly improving the efficiency of work.
In addition, through the warehouse management subsystem, can quickly and accurately generate the need for a variety of reports, and products from the warehouse, out of the warehouse and other links in the whole process of tracking, to provide effective management.
2.3 Comprehensive Information Management Platform
The comprehensive information management platform is used to communicate with each client system, and is responsible for summarizing the information generated by the logistics management client system, warehouse management client system, etc., and at the same time, the comprehensive information management platform releases the information to the client system in need. Based on these data, you can query the detailed information of each link of cargo transportation and warehousing, and generate statistics and reports in a targeted manner.
2.4 Problems that can be solved
This system architecture can solve the following problems:
***1*** Higher labor costs. Traditional warehousing and logistics management belongs to the rough manual management, need to invest a lot of manpower in the warehouse of goods, container information, such as registration and management. For different materials need to be repeatedly checked, in the problem of commodity quality traceability as well as customer after-sales service, will cause a great waste of human resources. In the logistics process, a lot of manual intervention is needed to count the number of shipments, and after arrival at the port, manual counting and checking is still needed again according to the requirements, so the cost is high.
***2***Low efficiency. Due to the special characteristics of some commodities, in the warehouse, logistics and transportation phase are required to count the number, sometimes counting also need to be lifted with the completion of the time-consuming and laborious, the error rate is high.
***3***Slow response time. As a result of manual management mode, can not be timely statistics related to warehousing and logistics information, is not conducive to mastering the inventory dynamics, inventory analysis, but also not conducive to the use of scientific methods of management of the warehouse, reduce the amount of inventory, improve inventory turnover rate. So there is usually the case that "although the implementation of ERP, but the situation has not significantly improved, inventory is still very high, the order response time is still very slow! Or "the inventory is already very large, but the terminal is still often out of stock, order fulfillment rate is not high, and even continue to deteriorate the trend!"
The introduction of the system can be very good to help operators find timely problems in the logistics and warehousing process, shorten the problem-solving cycle, significantly reduce production costs, to achieve value-added assets, and improve competitiveness.
3 Conclusion
The introduction of RFID tag technology can combine the technical advantages of RFID itself with the needs of logistics and warehouse management, which greatly saves costs, speeds up the integration of the industry chain and improves competitiveness. At the same time, can greatly improve the traditional logistics, warehousing link operator's work efficiency; Enhance the traceability of goods, realize the inventory information timely statistical analysis. Thus, it can realize digital logistics and intelligent warehouse, which can track the whole process of goods, and also can network different warehouses in different places, carry out real-time warehousing statistics and allocation, and realize the whole process of information management from production, sales, transportation to warehousing. In addition, it can also help enterprises to utilize and deploy a variety of resources, effective control of business processes, and rapid response to customer demand. At the same time to help enterprises gradually eliminate management bottlenecks, improve management level, establish competitive advantages, improve influence.
