manufacturing control and data collection systems For any manufacturing control system a kind of drawback of an excessive dependence on up-to-date information about the products and other elements which move within the system is essential. Sensors: Wired sensors Wireless sensors Readers: Barcode readers RFID readers
Radio-frequency identification Radio-frequency identification (RFID) is the wireless non-contact use of radio-frequency electromagnetic fields to transfer data, for the purposes of automatically identifying and tracking tags attached to objects. Tags Antenna Reader
Bar code in compare to RFID in manufacturing control context When a part is complex, it may lack a convenient and scan able location for bar codes. RFID tags can be placed anywhere on the part, and scanned from any orientation. Unlike bar codes, RFID tags can store data for continuous production updates. Unlike bar codes, RFID tags are unaffected by the dust and grime common to industrial environments. RFID tags can provide monitoring of the arrival, continuous presence, and departure of specific parts to/from a cell, allowing for better management of routes and locations in the assembly environment.
