In modern smart logistics and flexible manufacturing systems, AGV (Automated Guided Vehicle) positioning functions like the human sensory nervous system, with RFID tags serving as the critical “coordinate points” embedded on the ground. As a core facility for discrete navigation, RFID tags are becoming a popular choice for AGV intelligence upgrades due to their flexible deployment and dual advantages in information exchange.

RFID Tags: The Discrete Navigation Foundation for AGVs
RFID (Radio Frequency Identification) tags consist of a chip and antenna, enabling centimeter-level point positioning and command transmission through contactless communication with AGV-mounted readers via electromagnetic fields. Their core value lies in:

Passive Operation: No power supply required; activated by energy from the reader (effective lifespan >10 years).

Data Carrier: Stores critical information such as station codes and path commands (capacity: 1kb–8kb).

Environmental Penetration: Capable of penetrating non-metallic materials (e.g., wood, plastic), adapting to complex conditions.

Key Performance Elements:

Scientific Selection: Four-Dimensional Matching Principles

1.Frequency & Material Determined by Scenario

Metal Environments (e.g., near machinery, racking areas):
Prefer metal-resistant tags (with ferrite magnetic layer), LF 125kHz, stable read range of 10–30 cm.

High-Traffic Pathways (e.g., sorting lines, intersections):
Use UHF tags with 2–8 m read range, supporting dynamic recognition of high-speed AGVs.

Wet/Corrosive Areas:
Opt for ceramic-encapsulated tags (IP69K) with epoxy resin sealing, resistant to acid/alkaline cleaning.

2.Installation Method Matched to Precision Needs

3.Chip Grade Determined by Data Interaction Depth

Basic Navigation: Read-only tags (store path ID; cost <$0.50 per unit).

Smart Interaction: Read-write tags (update task commands in real-time; support NTAG213 protocol).

4.Survival Design for Extreme Environments

-40°C Cold Chain Warehouses: Silicone material tags (resistant to low-temperature brittleness).

High-Temp Foundries: Ceramic tags (withstands >200°C).

High-Pressure Washdown Zones: Fully sealed stainless steel housing (resists 120 Bar water impact).

Pitfall Avoidance: Critical Errors in RFID Applications

Metal Interference Blind Spots: Failure to use metal-resistant tags causes read failures (>90% failure rate in metal environments).

Tag Collision: Omission of anti-collision algorithms in dense deployments (standard protocol: ISO 18000-6C).

Height Mismatch: Reader-tag distance exceeding specifications (UHF tags require control within 1.5× wavelength).

Data Security Gaps: Failure to enable encryption protocols (recommended: AES-128 or DESFire EV2).
