一种集成北斗与智能算法的核安保监管终端设计与实现OA

Safety supervision during the transportation of nuclear materials serves as a critical guarantee for the development of the nuclear industry.Aiming at the current deficiencies of supervision equipment,including low integration,high data security risks,insufficient endurance,and anomaly recognition relying on manual threshold judgment,this paper designs and implements a highly integrated package supervision terminal.Meanwhile,a multi-sensor data fusion algorithm based on the Improved Adaptive Kalman Filter(IAKF)and a lightweight Isolation Forest anomaly detection algorithm with improved split points(iForest-SP)are proposed.Taking the ARM Cortex-M4 microcontroller as the core,the terminal integrates a radiation detection module,an infrared temperature sensing module,a PUF hardware encryption module,a BDS-3 short message service and positioning module,a tamper-proof monitoring module,an attitude monitoring module,a Bluetooth/4G/Ethernet multi-mode adaptive communication interface,and an independent power supply unit.All modules adopt a miniaturized integrated structural design and are connected via quick-release screws and waterproof aviation connectors for convenient maintenance.Furthermore,the proposed IAKF multi-sensor data fusion algorithm and iForest-SP anomaly detection algorithm are employed to address the challenges of sensor environmental interference and accurate anomaly identification from multi-source heterogeneous data.Experimental results demonstrate that the anomaly detection accuracy of the package supervision terminal is≥97.9％,with a single endurance of more than 21 days,meeting the supervision requirements of nuclear material transportation across all scenarios including road,railway and offshore routes.The research results provide a highly reliable hardware foundation and intelligent analysis method for the safety supervision of nuclear material transportation,possessing favorable engineering application value.
