1. Application background
Warehousing has always played the most important role in the logistics system. With the rapid development of modern manufacturing industry and the urgent need for informatization, higher requirements have been put forward for warehouse operations, such as warehouse delivery, warehouse entry, and warehouse internal management. Modern warehouse storage not only completes simple batch processing of goods in and out, but also makes clear database records of the types, quantities, production attributes, stacking positions and other information of goods in the warehouse. In order to obtain accurate product data and supply chain information at all stages of the logistics chain. In terms of warehouse management, one-dimensional barcode/two-dimensional barcode identification technology has been widely used in the management of item classification and labeling. However, its barcode technology relies on visible light scanning reflection, has low recognition rate, is easy to be damaged and stained, is sensitive to media such as water and oil pollution, and has a limited amount of stored information, which affects its application in large-scale logistics management.RFID Radio frequency identification technology is a typical representative of radio frequency automatic identification technology. Its high recognition accuracy, reliable performance, large amount of stored information, and oil and sewage resistance are especially suitable for automatic identification requirements in extreme working environments. The use of RFID tags to replace barcodes and other identification products can effectively complete the automatic management of warehousing, and realize automatic collection, automatic processing and information reporting of product information.
2. System introduction
In warehousing management, mobile RFID handsets and fixed readers are mainly used to complete the warehousing management of warehouse materials (with electronic labels). If the hand-held machine is used to check the materials, the basic operation is: use the hand-held machine to scan the electronic label attached to the material, and the hand-held machine communicates with the background database through wireless means (wifi wireless communication or GPRS/3G data communication). For data interaction, the WMS system transmits the relevant information to the logistics equipment through the WCS system to complete the relevant operations. If a fixed reader is used to manage the incoming and outgoing of materials, the basic operation is: when materials are transported, through the radio frequency coverage area equipped with a fixed reader, the reader reads the materials posted on the material Electronic label information on the . The fixed reader communicates with the COM port/Ethernet port to upload the data to the PC of the warehouse workstation. The terminal PC completes the data interaction with the background database through the network, and the terminal PC can complete various service requests at the same time.
3. Application cases
In order to manage the needs of a well-known third-party logistics company at home and abroad, in order to solve the integration of logistics, vehicle flow and information flow, effectively trace the production, storage, inventory, delivery, customs declaration and other links of goods, after multiple rounds of technical bidding and on-site Testing, our company’s mobile WMS solution based on RF-H5000 defeated Motorola, successfully signed the contract, and the first phase of the project has been successfully delivered.
The third-party logistics company covers a total area of more than 580 acres, including 72,000 square meters of modern and new professional warehouses, 70,000 square meters of container and cargo storage yard, 12,000 square meters of bonded warehouse, 60,000 square meters of general warehouse, and 30,000 square meters of storage yard. Most of the logistics company’s customers are overseas customers, the pallet information is complex and diverse, the barcode length is up to 60 digits, and it needs to be split and combined. The warehouse site environment is complex. In the past, there were more than a dozen order entry staff working overtime, which often caused information input errors. , input delays, etc., resulting in discrepancies between the actual accounts, the transport fleet often waits in line, and the goods cannot be sent out accurately.
The RF-H5000 mobile WMS solution provided by Soft Rich Company solves the fast and accurate collection of information from the receipt, quality inspection, warehousing, inventory, and delivery of goods. The verification program interacts with the background in real time. When there is a scanning error, the background sends a reminder command in real time, which effectively solves the error in the input link. For the on-site data transmission problem, we adopted the mode of combining WIFI and GPRS (3G), which not only improves the transmission efficiency, but also reduces the user’s use cost.
