Using LabVIEW to Integrate RFID System and Database for Supply Chain Efficiency Improvement

An RFID-based traceability system and its wireless communication technology are emerging to the supply chain management around the world. RFID (Radio Frequency Identification) is one of the greatest innovations in the field of real-time information acquisition technique without the line-off-sight. Current large data storing capability and fast identifying speed are key features of an RFID technology, and these two advantages enable RFID to replace the traditional barcode in an increasing pace. The technology is not only to substitute the barcode with RFID tags, but also improves the effectiveness of mass information transmission on the supply chain control system. This study constructs a dynamic automatic conveyor system to demonstrate real time monitoring of material flow with RFID tags. A database is constructed by Access System (AS) and integrated by the powerful LabVIEW System with high-speed signal acquisition hardware, server computer and software. The developed interface is able to identify whether the products are entering correct places of the assigned warehouse. Therefore, the material flow from supplier, manufacturer, distributor and customer can be controlled, monitored and coordinated. This mechanism of supply chain operations can improve the efficiency and performance of all the supply chain members in current industrial systems.
