RFID technology

RFID (radio-frequency identification)

RFID is an "identification using electro-magnetic waves" and describes a technology for transmitter-receiver systems for automatic and contactless identification and localisation of objects using radio waves.

An RFID system consists of two parts: a transponder (RF-tag), which is located at or in the object and contains an identifying code, and a reader that reads the identity.

We use two types of transponders for the different areas of application. We use HF-tags suitable for short distances as well as UHF-tags that are more suitable for larger distances.

At hobb, we use RFID technology for the following applications.

The entire logistics from incoming to outgoing goods within our company is controlled using RFID. For the in-house transport of our products, we use HF-tags (HF-chip), wich are built into the slave boards.

The HF-tags control the material flow, update the products status and show information for the machine operator.

Costumers using the respective technology can also access the product information upon goods receipt via the information that is filed within the code of the HF-tag.

We use RFID controlled tracking system for the wood material boards in our raw board warehouse. This is used to locate the stored raw boards in the "randomly" organised warehouse, thus ensuring short access times.

This works using the RID tags that are fixed to the wood maerial boards. The labels are fed with energy using aerials that are attached to the ceiling. A so-called STAR aerial detects the RFID labels and calculates the exact location of the wood matrial boards.

After entering the material number, the fork lift driver can see the position of the required pallet on the screen in a virtual warehouse. Ifseveral pallets with the same number are stored, the fork lift driver can select the pallet with the shortest ccess time or the pallet that has been stored the longest (First-in Fist-out).

Furthermore, the system can control the supply of the wood material boards to the saw. The saw operator and the fork lift driver can see on the screen, which palet is being transported. This ensures that the saw operator uses the correct cutting plan with the correct material!
