The Eforthink Intrinsically Safe Dual-Frequency Differential GNSS Version Intelligent Positioning Work Permit Identification Card is a cutting-edge RTLS (Real-Time Location System) terminal designed for seamless indoor and outdoor personnel tracking. As a Personnel Location Tag, it integrates advanced RTLS Technology to deliver high-precision, real-time positioning across complex environments.
This device combines UWB location technology (802.15.4 2011 UWB standard), uBeacon, iBeacon, AOA (Angle of Arrival), and ZigBee communication (915MHz/2.4GHz) to ensure robust indoor positioning. For outdoor scenarios, its dual-frequency GNSS module outperforms single-frequency systems, achieving centimeter-level accuracy through dual-frequency RTK differential positioning when paired with ground-based differential reference stations. This hybrid approach enables location finding devices to operate flawlessly in mixed environments, providing administrators with real-time visibility into personnel movements.
Key safety features include boundary alerts, proximity warnings to danger zones, and an SOS emergency button. The terminal’s 2.7-inch e-ink screen displays critical information such as messages, weather updates (network-dependent), and alarm statuses. As part of a comprehensive rtls real time location system, it supports instant distress reporting, fire/flood/hazardous material leak alerts, and automated health monitoring, ensuring rapid emergency response.
