- Co to jest RFID Technologia?

Radio Frequency Identification (RFID) is a wireless communication technology that uses electromagnetic fields to automatically identify andd track tags attached to objects. An RFID systems consistents of three primary configents: a tag (or transponder), a reader (or considerator), and an antentinna. The tag contris a microchip that stores data - such as a unique identifier, product detals, or batíotien - antin anthattent transmits a tis tis reader.

Low- frequency (LF) tags (125- 134 kHz) have short read ranges (a few centimeters) and are less affected by metal or liquids. High- frequency (HF) tags (13.56 MHz) offer read ranges up to about one meter and are present in control and item- level tracking.

In AGV environments, RFID tags are typically addixed too loads, palets, or conteners. The tags may be passive (powild by by thee reader 's signal, no internal battery) or active (with an onboard battery that extends read range ande enables continuous signaling). Passive UHF tags are thee most cost- effective for most loadeng contaclios, while active tags are reserved for highvalue, large, or constantly mog assets.

3. Zwiększone pole manewru i efektywność

Automated load scanning wigh RFID is signitantly faster than manual barcode scanning. An AGV can pass over a load at normal travel speed while thee reater captures the tag data in milliseconds. This eliminates the stop-and- scan overhead that slow s manual processes. Moreover, bulk reading allows an AGV to verify an entire pallet of tagged items ion one pass, reducing handling time.

4. Improved Inventory Accuracy andControl

RFID- enabled load tracking provides precise, real-time inventory data. Every time a load is picked up, dropped off, or moved by an AGV, the system automatically updates inventory counts.
