Por que o rastreamento de EPI é mais desafiador em ambientes metálicos?
Em oficinas de fabricação, metallurgical plants, or construction sites, most PPE equipment (como capacetes, ferramentas, and work clothes) contains metal parts. Ordinário Tags RFID are prone to signal attenuation, misreading, or failure to be recognized on metal surfaces. Portanto, metal-mounted Tags RFID specifically designed for metal environments are crucial.
By optimizing the RF path and tag deployment, interference can be effectively reduced, enabling RFID PPE tags to maintain a read accuracy of over 95% in complex industrial environments.
How RFID PPE Tags Work and Their Classification
A typical PPE tracking system consists of RFID PPE tags, a fixed reader/writer, uma antena, e uma plataforma de gerenciamento back-end. When workers carrying safety helmets or tools with metal-mounted RFID PPE tags pass through the detection point, the system automatically records the status of personnel and equipment, achieving “person-object binding” and automatic compliance detection.
Atualmente, commonly used industrial-grade RFID PPE tags are divided into three categories:
- UHF anti-metal interference tags (metal-mounted RFID PPE tags): used for metal safety helmets, wrenches, and other tools;
- Sewn flexible tags: used for fabric personal protective equipment, such as protective clothing and vests;
- High-temperature resistant tags: used for high-temperature working environments such as welding and casting.
RFIDHY testing found that metal tags optimized for the UHF band improved read stability by 38% in metal tool tracking scenarios.
Many companies have experienced poor results after deploying RFID tags for PPE,mainly due to complex environments and unoptimized reader placement. RFIDHY has made improvements based on this,specifically in the following aspects:
- RF Simulation: Predicting the reflection intensity of metal-mounted PPE RFID tags at different heights and angles;
- Reader Power Adjustment: Dynamically balancing identification coverage and interference;
- Signal Path Analysis: Avoiding “pontos cegos” caused by metal reflections;
Practical testing shows that compared to traditional experience-based deployment solutions, the RFIDHY RFID PPE tag deployment solution can improve the read success rate by approximately 22%.
