Using RFID systems to achieve efficient and transparent cargo warehousing and logistics operations.

In this project, UHF industrial readers were used to collect and transmit material information from transport pallets, while the I/O interface enabled rapid data transmission to the ERP system. Non-contact detection of incoming and outgoing goods significantly improved the transparency of inventory levels. This allowed users to achieve precise and rapid inventory control.        

Previously, simply placing or locating materials or adjusting inventory for slightly different types of goods required numerous steps. With increasing demands for logistics service quality, ensuring reasonable procurement and inventory control has become particularly important.        When do materials arrive or leave the warehouse? How much material is there? What items are included? Where are products stored? The ERP system must be able to visualize this information in real time and provide transported materials as needed. The system integrator chose to use UHF RFID for data transmission. Industrial readers use ultra-high frequency signals to write or read information on passive RFID tags and transmit it to the IT network via an interface. Thanks to UHF technology, this data exchange can be completed between readers and tags several meters apart. Information can also be read when objects pass by at high speed. This chemical company uses recyclable pallets to transport goods. RFID tags, each with a unique ID, are embedded in each pallet, tightly linking data to the transported materials or products. The RFID identification process is automated, while the rewritable tags allow for multiple uses of the pallets. The tags are first written with information in the packaging area. In this area, the reader matches the specific material information on the pallet before the pallet proceeds to the cargo center. Another type of reader is installed along the conveyor belt in the warehouse. These record the movement of goods in and out and register the exact location of the pallets. I/O modules are used between the RFID readers and the IT network, enabling rapid transmission of information from the readers to the ERP production control system.        Thanks to RFID technology, data on incoming and outgoing goods can now be continuously synchronized with the ERP system in real time to maintain inventory levels. This provides significant convenience and access to real-time information on available transport capacity and location of pallets, helping to optimize the use of space resources. Furthermore, understanding which goods are in motion meets the safety requirements of the chemical industry. The increased efficiency ultimately has a positive impact on costs. In other words, the manual steps required for warehouse management are greatly reduced, and material costs are also significantly lowered.
