I. Industry background

Simple and static traditional warehouse management mode has many shortcomings, such as huge material inventory, difficult material tracking, low turnover efficiency of capital and materials, high labor cost, backward information and means of logistics management, etc., which can not adapt to the new warehouse management needs. Break the traditional warehouse management mode, actively explore new information management technology, on the basis of adapting to the original management process of the enterprise, build a new warehouse management information system platform, coordinate the operation of each link, ensure timely and accurate warehousing operations and real-time transparent inventory control operations, reasonably allocate warehouse resources, optimize warehouse layout and improve warehouse operation level, improve warehouse service quality, save labor force and inventory space, reduce operation costs, so as to enhance the competitiveness of enterprises in the market.

Warehouse management of enterprises is the management of warehouse and materials in warehouse, and the planning, organization, control and coordination process of enterprises in order to make full use of warehouse resources to provide warehouse services. As a link between producers and consumers, it plays a vital role in the whole logistics and economic activities.

Different enterprise scales and product categories have different warehouse management processes and requirements, but the core part lies in warehouse operations including warehousing and inventory control operations including warehousing and inventory. With the change of the whole production and manufacturing environment, the product cycle is getting shorter and shorter, and a variety of small production methods begin to rise, and the demand from the market puts forward higher requirements for warehouse management.

RFID warehouse management solution lies in optimized warehouse resource allocation, accurate warehouse operation control, and real-time and effective transparent transmission of warehouse data flow. The core content should include:

Visual access management

Visual warehousing management mainly covers goods (pallets) warehousing, warehousing, etc. RFID intelligent warehouse management system should be able to realize the visual management of real-time warehouse data in the management center. Real synchronization of physical flow and data flow.

Electronic tray and storage management

The realization of electronic pallet and storage position is the basis of visual and intelligent storage management. The goods in the warehouse are transferred and stored in units of pallets. By realizing electronic pallet, the identification of each pallet, real-time tracking of storage and transfer position can be realized. Combined with electronic (digital) warehouse location management, it can provide necessary data foundation for visual and intelligent warehouse management.

By dividing the physical space of warehouse into regions and assigning a label to each physical space, the goods in the warehouse can be effectively positioned and quickly retrieved.

Quick cargo location

When a certain cargo needs to be found, relevant cargo information is input into the handset, and the cargo is scanned within a certain range. When the cargo is scanned, the intelligent storage management system sends a prompt, which is convenient for quickly finding the cargo.

Related Systems (MES/WCS/SAP) Interface

Warehouse management system wms should not be an independent system, related data should be able to interact with existing production management (MES), EPR(SAP), and customer system (WCS) through certain interfaces to meet the actual management needs of the enterprise.

Realize the unification of information flow and physical flow

Due to the limitation of technical conditions, traditional warehouse management inevitably faces real-time data lag, which cannot accurately reflect the storage inventory and logistics situation in real time, resulting in serious disconnection between information flow and physical flow. Moreover, due to the manual identification of goods information, not only inefficient and error-prone, but also a large workload, the purpose of building an intelligent warehouse management system is to achieve the unification of information flow and physical flow in enterprise warehouse management by introducing effective technical means, and to achieve real-time visualization of RFID intelligent warehouse management.

II. Brief Introduction of Technology

RFID has been widely used in RFID manufacturing, RFID anti-counterfeiting traceability, RFID warehousing logistics and supply chain management, etc., bringing great technological innovation to these fields, especially in the field of RFID intelligent warehousing management system, because of the characteristics of RFID technology, it will greatly improve the collection speed of logistics information and logistics efficiency.

1. technical advantages

RFID technology is characterized by non-contact high-speed identification, it communicates in a wireless manner, RF tags can be read without exposing electrical contacts, so even if the RF tag items are placed inside the packaging material, they can also be identified. RFID RFID identification system can also identify multiple RF tags and high-speed RF tags at the same time, which can achieve the high efficiency of the circulation process of goods. The specific advantages are as follows:

1.1 contactless read-write

As long as the reader of the RFID system can read the information directly into the database without contact, this has a great advantage over the original information entered by the special document clerk, and can write various information of the logistics processing state into the label, which reduces a lot of information collection time for the next stage of the process.

1.2 Multi-tag simultaneous reading

RFID reader can read a plurality of RFID tags at a time, and the data is transmitted to the computer network system by the reader at one time. The speed of data acquisition and acceptance of articles is ten times that of scanning and acceptance of barcodes one by one, and it is much faster than the traditional method of using data acquisition of document entry and checking the name of goods to accept articles. Through the multi-readability of this RFID reader, efficient and rapid circulation of items can be realized.

1.3 Good penetration

The RFID tag attached to the item placed in the packaging material is paper, wood and plastic and other non-metallic or non-transparent materials can also be recognized normally by the reader, it has a good penetration, so that you can do not have to take the item out of the packaging material can be achieved to identify it quickly and conveniently.

1.4 Label storage data capacity is large

RFID tags store much more data than bar codes, bar code technology stores data can only indicate the type of items belong to, can not express the individual of each type of items, and RFID tags have large storage capacity, can store detailed information describing the items.

1.5 Strong adaptability to environment

Paper dirt may not see the words written on the paper, bar code in the dark environment bar code scanner can not scan out the bar code information, magnetic card no magnetic card can not be swiped, and RFID technology has a strong environmental adaptability, RFID radio frequency tags on water, oil and drugs and other substances have strong anti-pollution and light immunity, in the dirty environment or dark environment can still be very easy to collect the electronic information in the radio frequency tag.

1.6 Labels are reusable

RFID stores data as electronic data, and the carrier for storing data is an electronic chip. This chip has the function of repeated writing and can be reused to reduce the one-time investment cost of the project.

1.7 Miniaturization and diversification of label shapes

Reading RFID tags is not limited by size and shape, and does not need to match the fixed size and printing quality of paper for reading accuracy, which has a greater advantage than the application of barcode technology on articles that needs to be combined with the shape and size of articles. In addition, miniaturization of RFID tags can be more flexibly applied to control the production of products on the production line.

1.8 RFID Technology Systems and Data Security

Transferring the product data from the central computer to the workpiece will provide security for the system, avoid reading the data directly from the system and greatly improve the security of the system, and use encryption methods to protect the data in the RFID tag, which can ensure that the data is not read.
