Research on Indoor Personnel Positioning and Physiological Information Monitoring System

摘要:

为满足对室内高精度定位与人员生理信息进行实时监测需求，提出一种基于超宽带（UWB）、蓝牙低功耗（BLE）和射频分布技术的融合定位系统。采用UWB实现高精度定位，结合BLE进行信号补偿，通过射频分布技术扩大覆盖范围，解决复杂环境中的信号遮挡与精度下降问题。经测试，系统在无遮挡环境下定位精度优于10厘米，遮挡环境下通过多技术融合保持30厘米精度；生理监测模块实现心率、血氧浓度及汗液参数采集，误差小于10%。参考工业生产、密闭空间等典型应用，设计场景进行适用性及性能对比实验，证明系统设计合理性和应用价值。

Abstract:

To meet the demand for real-time monitoring of indoor high-precision positioning and personnel physiological information, this paper proposes a fused positioning system integrating Ultra-Wideband (UWB), Bluetooth Low Energy (BLE), and RF distribution technology. The system leverages UWB for high-precision positioning, incorporates BLE for signal compensation, and utilizes RF distribution technology to expand coverage, effectively addressing signal occlusion and accuracy degradation in complex environments. Testing results show that the system achieves positioning accuracy better than 10 centimeters in unobstructed scenarios, while maintaining 30-centimeter accuracy in obstructed environments through multi-technology fusion. The physiological monitoring module enables acquisition of heart rate, blood oxygen saturation, and sweat-related parameters with measurement errors below 10%. Drawing on typical applications such as industrial production and confined space operations, scenarios were designed to conduct applicability and performance comparison experiments, demonstrating the system's design rationality and practical application value.
