The difference between modern logistics enterprises and traditional warehousing industry is that their business model is built on the basis of the total logistics cost, which requires modern logistics enterprises to do a very good job in integrating processes and controlling static inventory. Therefore, warehouse management has become a very important implementation link, accurate understanding of inventory information is very important for enterprises, because it is an important guarantee to realize reasonable inventory or even zero inventory. The wms warehouse management system based on RFID technology is based on the traditional warehouse management system combined with RFID technology to achieve timely and accurate purchase, inventory control and delivery, reduce the overall cost of enterprises, improve customer service quality and ultimately enhance the core market competitiveness of enterprises.

WMS Warehouse Management System advantage of FID technology:
1. Penetration and screenless reading: Traditional bar code scanners must be able to read bar codes at close range and without objects in their way. RFID can penetrate non-metallic and non-transparent materials such as paper, wood and plastic for penetrating communication, without the need for light source and longer reading distance.
2. Fast identification speed: RFID reader can read the information in real time, and can process multiple labels at the same time, to achieve batch identification, greatly improving the reading efficiency.
3. Electronic tag data can be dynamically changed: the programmer can write data to the electronic tag, thus giving RFID tag interactive portable data file function, and write time is shorter than the printing bar code, and the tag can be reused.
4. Large data capacity: the large capacity of RFID is several M. With the development of memory carrier, data capacity also has the trend of expanding. In the future, the amount of data needed to be carried by articles will be more and more large, and the demand for the expanded capacity of labels will also increase accordingly, which is also in line with the future development trend.

Introduction of WMS warehouse management system based on RFID technology: The system includes six links, namely inventory, delivery, warehousing, picking, loading data preparation: all customer orders and delivered goods need to be recorded in the WMS warehouse management system in advance
1. Receiving link: using the selected item coding scheme to encode incoming items; Making goods label: write the coded information into the electronic label, print the paper label (proofreading) at the same time, and then glue the paper label and electronic together to become goods label; The goods are sent to the warehouse after the location is checked by RFID handheld machine; The wireless data terminal sends the incoming data to the on-site computer and updates the WMS warehouse management system database in time. The on-site computer automatically allocates the storage location, and gradually downloads the storage location number and corresponding item number of each operation to the wireless data terminal (handheld terminal or forklift terminal).
2. Loading link: each piece of goods is affixed with bar code, and passive labels are installed on the boxes after loading. The boxes of goods with passive labels are palleted according to the storage location read by the RFID handheld computer in the hands of the staff, and an active electronic label is installed on each pallet. Put the goods on each pallet separately on the corresponding shelves;
3. Picking link: The picking truck downloads the bulk order system in the WMS warehouse management system and automatically instructs the car to sort and pick goods according to the path; Confirm the information of the picking place, the system automatically indicates the quantity of "picking while dividing", and press the light to confirm after dividing the goods; The pick-up truck automatically receives instructions from the WMS warehouse management system, and guides the operator to the next pick-up operation in real time until all the bulk orders are completed.
4. Warehouse transfer link: When warehouse transfer is required, the system sends instructions to the RFID handheld computer in the hands of the operator. After seeing the instructions, the operator locates the corresponding goods and the corresponding quantity, moves the goods to the corresponding target library, modifies the information of the corresponding labels, and sends the corresponding data back to the WMS warehouse management system.
5. Outbound link: When it is necessary to be outbound, the system will issue outbound instructions to the RFID handheld computer in the hands of the operator. The operator will locate the corresponding drugs and quantity, take out the passive labels on the boxes of drugs, modify the corresponding data, and send the data to the WMS warehouse management system.
6. Stocktaking link: RFID fixed reader is installed on the shelf. The fixed reader scans the passive labels in the fixed area and transmits the scanned data to the system. The inventory can also be scanned by the RFID handheld in the hands of the operator and sent to the WMS warehouse management system for verification. In addition to the above functions, the system also has the function of positioning query, as well as intelligent alarm, which can quickly and effectively locate the location of goods, and timely notify the management of goods exceeding the predetermined indicators.

wms warehouse management system with RFID technology is the future development direction. In the long-term service process for logistics enterprises, it is found that the warehouse management system with RFID technology can effectively ensure the speed and accuracy of data input in each link of goods warehouse management, ensure that enterprises timely and accurately grasp the real data of inventory, and reasonably maintain and control enterprise inventory. Through scientific coding, it is also convenient to manage the batch and shelf life of the goods in stock. Using the system's warehouse location management function, we can grasp the current location of all inventory goods in time, which is conducive to improving the efficiency of warehouse management.
