In the current era where personnel positioning requirements are becoming increasingly refined, the 2D planar positioning system stands out with its utilization of UWB positioning technology. This system can achieve a positioning accuracy of up to 30 cm. By leveraging the PDOA algorithm, it innovatively realizes real-time personnel positioning on a 2D plane using a single base station. This breakthrough not only enhances the ability to control hazardous areas but also enables timely warnings before safety accidents occur and rapid responses to alarms in emergency situations, constructing a solid defense line for personnel safety.
(I) PDOA Algorithm-Driven Single-Base-Station Positioning
Based on the principle of the PDOA algorithm, a single base station board equipped with four antennas can precisely accomplish 2D positioning tasks. Compared to the commonly used wired synchronous timing approach with multiple base stations in the market, this solution significantly reduces the number of base stations and substantially lowers installation costs. Meanwhile, the design of the 485 interface enables the system to be easily integrated into various back-end systems, demonstrating significant advantages in terms of simple deployment, system stability, and cost control.
(II) Diverse Functional Modules for Comprehensive Safety Protection
Real-Time Personnel Positioning: The system can conduct real-time location tracking of personnel, enabling precise monitoring of personnel dynamics anytime and anywhere. It supports querying personnel location, coordinates, and trajectory information through multiple means such as card numbers and names, making personnel management more efficient and accurate.
Electronic Fence Protection: Hazardous areas and alarm rules can be flexibly set. When personnel approach hazardous areas, the system immediately sends out an alarm, effectively managing personnel activity ranges and ensuring they stay away from potential dangers.
SOS Alarm and Paging Function: On-site personnel can send SOS alarm information with a single press of a button on the positioning tag, triggering an alarm mechanism in real-time. Monitoring room or back-end personnel can then initiate calls to corresponding personnel or all staff through the system, enabling fast and effective communication and command.
Historical Trajectory Storage and Playback: The system has the capability to store personnel movement trajectories over a long period, providing strong decision-making bases for incident handling. It also supports playing back the activity trajectories of personnel within a specified time period based on card numbers and areas, facilitating post-event tracing and analysis.
