摘要/Abstract

摘要： 研发构建的核电厂放射源复合定位在线监控系统将放射源管理工作与超宽带技术(UWB)、北斗定位技术相结合,实现室内外无缝高精度追踪。室外采用平面精度衰减因子(HDOP)评估与卡尔曼滤波算法提升定位数据的可靠性;室内场景将时分复用(TDMA)技术应用到UWB抵达时间差(TDOA)定位系统中,在最大化系统并发容限的同时,实现±10 cm级高精度定位,满足了对放射源微小移动的精确监控需求。借助核电厂专用5G实时传输,成功实现智能化、数字化全流程管控,保障了放射源贮存、运输和使用的安全。引入3D技术提升监控的直观性与操作效率,为核电厂放射源安全监管提供新思路、新方案。

Abstract: The nuclear power plant radioactive source composite positioning online monitoring system developed and constructed in this research and development combines the radioactive source management work with Ultra-Wide Band ( UWB) technology and Beidou positioning technology to achieve seamless and high-precision tracking both indoors and outdoors. For outdoor scenarios, the Horizontal Dilution of Precision (HDOP) factor is adopted for evaluation, and Kalman filtering is used to enhance the data reliability. For indoor scenarios, Time Division Multiplexing Access (TDMA) technology is innovatively applied to the UWB Time Difference of Arrival (TDOA) positioning system. This maximizes the concurrent tolerance of the system while achieving a high-precision positioning of ±10 cm, meeting the precise monitoring requirements for the tiny movements of radioactive sources. With the help of 5G real-time transmission dedicated to nuclear power plants, intelligent and digital full-process control has been successfully achieved, ensuring the safety of radioactive source storage, transportation and usage. The introduction of 3D technology enhances the intuitiveness and efficiency of monitoring, providing a new approach for the safety supervision of radioactive sources in nuclear power plants.
