Upgrading of Intelligent Warehouse Management System Based on RFID Technology- Taking Company as an Example

With the continuous development of e-commerce in China, more and more attention has been paid to modern logistics. The competition in the new era is not only in the fields of technology, cost and management, but also in the comprehensive competition of supply chain. The traditional warehouse management system is mainly completed by human resources, which consumes a lot of manpower and material resources and has low efficiency. It can no longer meet the needs of the development of modern e-commerce logistics. New retail industry is changing. New logistics has become the core of new retail form. Developing intelligent warehousing has become a solution to advance intelligent logistics. Radio Frequency Identification (RFID) technology has the advantages of large data storage, fast information reading and storage, and can effectively solve the problems of low efficiency, low accuracy and easy interference in information transmission of traditional warehouse management system. Based on the analysis of the existing problems of company A in warehouse management, this paper proposes to use RFID technology to optimize and upgrade it. Keywords— RFID technology, intelligent , warehousing, logistics, digitalization. With the close integration of network technology with various real industries and financial economy, China's agriculture, industry and commodity service industry have achieved new development. At the same time, they are facing new opportunities and challenges. Logistics, as an important part of commodity trade, plays an increasingly important role. However, our t raditional logistics network has been insufficient to meet the increasingly vigorous transportation needs. The warehouse management system also needs to be upgraded urgently. At present, the intelligent warehouse management system is integrated with wireless communication technology and RFID rad io frequency technology. These new technologies enable the existing warehouse management system to be reconstructed and intellectualized, and use the flexibility of wireless network wiring to meet the special needs of data close-range and low-speed in intelligent warehouse management. At the same t ime, along with the development of RFID radio frequency technology, the whole process of goods from inbound to outbound has also undergone innovative changes and leaps and bounds. Because of the non-contact and fast reading and writing characteristics of RFID, the goods can basically be intellectualized and mechanized in wa rehousing, discharging and picking.

PROBLEMS
Fro m suppliers supplying commod ities, sorting commodit ies into warehouses, informat ion registration, and then determining the location of commodity storage for storage, to commodit ies into production workshop for production, and finally to new commod ities out of warehouses, this step-by-step process is more complex.

Framework of warehousing management:
⑴.Storage of goods. Suppliers supply commodities toproducers. Warehousing centers grasp relevant informat ion of commodit ies from suppliers (such as the name, quantity, specifications of co mmodit ies), and determine the storage location of commodit ies. Warehousing centers arrange inspection and storage of commodities when they receive commodities.
(2) Management of goods in warehouse. The management of goods in warehouse must also follow certain standards. For example, some goods consume fast, some goods consume slowly, and some goods must be stored under special conditions, so their storage location needs to be strictly controlled. Moreover, there are certain requirements for the storage of similar but different specifications of co mmodit ies. These problems make it necessary to confirm that the goods are in accordance with the location when they are stored.
(3) Goods out of warehouse. In the warehouse management procedure, if the customer has issued an order to the sales department, the sales department will send the customer's order requirements to the warehouse management depart ment, and the warehouse management system will confirm the goods location.

2.Problems in warehousing management:
(1) Hu man factors have great influence and lack of decision-making ability. If the management mode is basically manual management, a large nu mber of staff need to be arranged in warehousing operations, such as warehousing, inventory and warehousing, which increases the cost of management and also affects the efficiency of work. Once problems arise in the intermediate work, the situation can not be transmitted to the higher level in t ime, and some staff's mishandling will lead to the inaccuracy of the inventory work, the upper leadership can not make correct decisions, and can not accurately understand the storage, in-storage and out-of-storage operations of the inventory, which will cause losses.
(2) The use of bar code technology. Nowadays, barcode is often used in warehouse management system to improve the speed of collecting goods informat ion. Co mpared with tradit ional manual paper records, it does improve the efficiency. However, in the face of increasingly frequent logistics warehousing needs, the drawbacks of barcode technology are beco ming more and more prominent, such as slow identification speed, inaccurate reading of information and less information.
(3) Visualization operation can not be realized. More and more users hope to see the goods informat ion and dynamic transportation status in real time, instead of the static logistics informat ion on the client side. This will require enterprises to further implement intelligent logistics strategy to meet the needs of users, while realizing the dynamic feedback of cargo transportation status. Intelligent logistics can be more conducive to enterprises for targeted analysis and decision-making, and imp rove all aspects of enterprises. Save work efficiency.

inevitably exposed to the risk of breakage. Similarly, in warehouse management, some co mmod ities are o f the same kind and have very low differentiation, wh ich makes warehousing management more difficult. Similar commodit ies may lead to staff negligence and make two different commodities mixed together.

OF INTELLIGENT WAREHOUS E
MANAGEMENT SYSTEM BASED ON RFID TECHNOLOGY The warehouse management system based on RFID can effectively realize the visual management of commodity inventory information through the application of RFID technology and wireless network technology, thus greatly imp roving the efficiency of warehousing operations. Based on these requirements, we can get several main modules of the system: user management module, stock management module, warehousing management module, as well as goods management, inventory statistics management module.

Fig. 1 Performance structure of warehouse management system based on RFID Technology
In the software structure design of digital logistics warehouse management system based on radio frequency identification technology, the functional module flow of the system is designed separately, the control structure of the system is optimized, and the operation efficiency of the system is improved. The warehouse is composed of warehousing temporary storage area, storage area and out of storage temporary storage area. RFID access control devices are installed at storage and storage outlet. The warehouse is designed as an automatic three-dimensional warehouse, equipped with three-d imensional shelves and roadway stackers. The quantity depends on the size of the warehouse. In order to monitor the warehouse environment in real t ime and install a suitable number of temperature, illu mination intensity and humidity sensors, the sensor transmits the environmental information to the monitoring system through the network. When the environmental informat ion of the warehouse exceeds the set value, the system sends out alarm instructions and displays the reasons for the alarm. The alarm is sent out by the warehouse admin istrator. The warehouse administrator processes and records the alarm in t ime. The reason of the  /dx.doi.org/10.22161/ijels.4.3.40  ISSN: 2456-7620 alarm is summarized and analy zed regularly and the suggestions for improvement are put forward.
In the goods management module, the main functions include inventory management, inventory, inventory early warning. Detailed function design: add, modify and delete warehouse informat ion; add, modify and delete and disable goods allocation; view inventory information and inventory situation of each warehouse location; adjust the warehouse location on the visual interface, regard the whole backstage as the warehouse location adjustment component, so as to reduce energy consumption and save running time of the system. In the user management module, it mainly includes user login control and user management. In the user's login control, the load driver is used to obtain the connection object, and the state statement is created to generate the processing result data set and release the connection. When the user enters the username and password and clicks on the login, the data input by the user will be processed in the background, matching the account and password in the database. If the match is successful, the login will succeed, otherwise the prompt will fail, and the main page will be returned. For the purpose of ensuring the confidentiality and reliability of the system, the storage management system uses the management form of mu lti-level users. Users are d ivided into several levels: supervisors, system managers, purchasing personnel and warehouse managers. Different levels of authority, mult i-pronged, clear d ivision of labor, conducive to the smooth operation of the system.
In order to rationalize inventory and reduce inventory cost, statistical software can be used to invoke information such as commodity category, quantity, date of entry and exit, existing inventory, goods damage and order satisfaction rate, so as to calculate the period of entry and exit, monthly demand and average level, off-peak season analysis, annual total demand, roughness analysis, overstocked commodity varieties and quantity, and goods loss rate and so on, assist managers to make scientific demand forecasting, and provide data reference for improving warehousing conditions and commodity production plan.
RFID technology combined with co mputer technology and pallet management can optimize the business process of distribution center. When warehousing, the goods are scanned on the conveyor belt, then directly stacked on the pallet. The pallet is automatically sent to the corresponding floor by the hoist under the control of the system. Finally, the forklift t ruck sends the pallet to the allocated storage space of the system. When discharging fro m the warehouse, the forklift truck sends the target tray to the hoist according to the system instruction and the first-in-first-out principle, and then sends it to the sorting center for sorting. Through the effective management and applicat ion of the tray, the number of cargo handling and the probability of damage are reduced, and the operation efficiency is imp roved. The application of RFID technology improves the speed of goods searching, reduces the occurrence of commodity out-of-sale, shortens the time of supply and marketing planning, thus reduces the stock occupation funds, reduces freight, and makes the retailer's co mmodity sales meet in time.

V. CONCLUSIONS AND SUGGES TIONS
Co mbin ing RFID technology with warehouse management to improve the accuracy of warehouse management data can not only overcome the shortcomings of traditional manual management, but also reduce labor costs with the improvement of automation level of warehouse system. In recent years, the technology of RFID has become a hot spot in log istics informationizat ion, especially in the promotion of foreign powerful enterprises, which makes the application prospect of this technology in China receive much attention. As far as the whole country is concerned, the application cost of RFID is too high, the technical standards are not uniform, and the government has not played a leading ro le in the process of its application and promotion, which makes enterprises show cautious attitude in the face of RFID, so the promotion and application of RFID in China is still in a very slow starting stage. In order to pro mote the development of RFID in China's logistics field, we should actively participate in the formulat ion of international standards and establish a unified RFID system; the government should drive enterprises to promote the exchange and research of RFID. Through the establishment of an industrial alliance for the application and promotion of RFID, and under the leadership of the relevant departments of the state, we will work with relevant manufacturers, research institutes and user departments to launch products and technologies with distinctive features, and actively pro mote extensive international exchanges between domestic enterprises and relevant units in the fields of RFID hardware, software and applications.
