system introduction
Existing SFC system data collection generally uses barcode data collection, and barcode labels are attached to products or packaging. The data collection methods are manual and automatic, and there are the following problems:
1. Manual: the operator holds the scanner to align the product barcode collection (disadvantages: manpower is required, there are human error factors)
2. Automatic: install the automatic scanner on the pipeline (disadvantages: high rate of missed scanning, high equipment cost)
In order to solve the above problems, RFID readers are fixedly installed in the pipeline, and RFID electronic tags are installed or attached to the products or packing pallets. When the products pass the recognition range of the RFID readers, inductive automatic data collection is realized.
System composition
? RFID reader,
? TCP/IP data collector,
? RFID electronic tags (ISO15693 13.56MHz)
? System data monitoring center
system structure
Use 13.56MHz high-frequency RFID electronic tags, RFID readers, and TCP/IP data collectors to write the pallet information into the RFID electronic tags and fix them on the assembly line pallet, install the RFID reader on the assembly line data collection station , When the pallet passes through the station, the RFID reader will automatically collect (radio frequency induction) the pallet information and transmit it to the SFC system center through the network
System Features
1. Fast data collection speed: effectively avoid collection difficulties due to bar code quality, lighting, etc.
2. The scan miss rate is almost zero: the floor scan rate is greatly reduced, and the product line is stopped due to missed scans.
3. Reduce the cost of consumables: The first investment cost of electronic tags is high, but they can be recycled and used repeatedly. Long-term evaluation can greatly reduce costs.
4. Reduce equipment costs: Automatic data collectors are expensive, and the use of RFID readers can save equipment costs
