The difference between modern logistics companies and the traditional warehousing industry is that their business models are based on overall logistics costs, which requires modern logistics companies to do a good job in integrating processes and controlling static inventory. As a result, warehouse management has become a very important implementation link. Accurate understanding of inventory product information is very important for companies, because it is an important guarantee for achieving reasonable inventory or even zero inventory.The wms warehouse management system based on RFID technology developed by Tianjin Xiaobee combines the most advanced on the basis of the traditional warehouse management system.RFIDThe technology realizes timely and accurate purchase, inventory control and delivery, reduces the overall cost of the enterprise, improves the quality of customer service, and ultimately enhances the core market competitiveness of the enterprise.
Advantages of WMS warehouse management system based on RFID technology:
1. Penetrating and unobstructed reading:
The traditional bar code scanner must be close and without obstructions before it can read the bar code. RFID can penetrate non-metallic and non-transparent materials such as paper, wood, and plastics for penetrating communication. It does not require a light source and has a longer reading distance.
2. Fast recognition speed:
Via RFIDReaderThe information can be read instantly, and multiple tags can be processed at the same time to realize batch recognition, which greatly improves the reading efficiency.
3. The electronic label data can be changed dynamically:
The programmer can be used to write data into the electronic tag, which gives the RFID tag an interactive portable data file function, and the writing time is shorter than that of printing a bar code, and the tag can be reused.
4. Large data capacity:
The maximum capacity of RFID is several M. With the development of memory carriers, the data capacity also has a trend of continuous expansion. In the future, the amount of information that items need to carry will become larger and larger, and the demand for the expansion of the tag’s capacity will increase accordingly, which is also in line with the future development trend.
Introduction of WMS warehouse management system based on RFID technology:
The system contains six links, namely, inventory, delivery, warehouse transfer, picking, and loading
Data preparation: All customer orders and delivered goods need to be entered in the WMS warehouse management system in advance
1. Receiving link:
Use the selected item coding scheme to encode the inbound items; Make goods label: write the coding information into the electronic label, and print the paper label (proofreading) at the same time, and then glue the paper label and the electronic together to become the goods label ; After checking the location by RFID handheld, the goods are sent to the warehouse; the wireless data terminal sends the actual status of the warehouse to the on-site computer to update the WMS warehouse management system database in time; the on-site computer automatically allocates the location and gradually changes the location of each operation The location number and the corresponding item number are downloaded to the wireless data terminal (handheld terminal or forklift terminal).
2. Delivery link:
Each piece of goods is affixed with a bar code, and after the box is packed, a passive label is installed on the box. The boxed goods with the passive label are palleted according to the warehouse location read by the RFID handheld device in the hands of the staff. An active electronic label is installed on each tray. Put the goods on each pallet on the corresponding shelf;
3. Picking link:
The picking truck downloads the batch order in the WMS warehouse management system, and the system automatically instructs the trolley to sort and pick the goods according to the optimal path;
After confirming the picking position information, the system will automatically indicate the “sort while sorting” quantity, and press the light to confirm after sorting; the picking truck will automatically receive instructions from the WMS warehouse management system and guide the operator to the next picking position in real time until all batches are completed Order.
4. Library transfer link:
When the warehouse needs to be moved, the system sends an instruction to the RFID handset in the hands of the operator. After seeing the instruction, the operator locates the corresponding goods, corresponds to the quantity, moves the goods to the corresponding target library, and modifies the corresponding label information after completion. And send back the corresponding data to the WMS warehouse management system.
5. Delivery link:
When it needs to be out of the warehouse, the system sends out the warehouse instruction to the RFID handset in the hands of the operator. The operator locates the corresponding medicine and quantity, takes out the passive label on the medicine box, revises the corresponding data, and sends the data to the WMS warehouse In the management system.
6 inventory links:
Install RFID fixed readers on the shelves, and the fixed readers scan the passive tags in the fixed area and transmit the scanned data to the system. You can also use the RFID handset in the operator’s hand to scan the inventory and send it to the WMS warehouse management system for comparison and verification.
In addition to the above functions, the system also has a positioning query function and an intelligent alarm function, which can quickly and effectively locate the location of the goods, and the system will promptly notify the management personnel to deal with the goods that exceed the predetermined index.
The WMS warehouse management system using RFID technology is the future development direction. Tianjin Bee has discovered in the long-term service process for logistics enterprises that the warehouse management system using RFID technology can effectively ensure the speed of data input in all aspects of cargo warehouse management. And accuracy, to ensure that the company can timely and accurately grasp the real data of the inventory, and reasonably maintain and control the company’s inventory. Through scientific coding, it is also convenient to manage the batch and shelf life of the stocked goods. Using the system’s location management function, you can also grasp the current location of all inventory goods in a timely manner, which is conducive to improving the efficiency of warehouse management.
