Research on high-precision personnel positioning and contact monitoring based on Bluetooth and UWB fusion

This study proposes a system that fuses UWB and Bluetooth technologies to improve the positioning accuracy and stability of personnel trajectory tracking and contact monitoring. Bluetooth technology is used for low-power proximity communication and UWB technology provides high-precision positioning combined with a particle filtering algorithm to fuse the data and analyse the relationship between 200-500 trajectory points. The experimental results show that the system has high positioning accuracy and good stability, and can provide key technical support for personnel control, security and resource optimisation in multiple locations.
