High-Voltage Power Supply for Explosive Detection Systems: Multi-Mode Data Fusion and Analysis

Modern explosive detection systems require high sensitivity and reliability under complex environmental conditions. Single-mode detection often fails to achieve rapid and accurate identification, making multi-mode composite detection a critical approach. High-voltage power supplies serve as the core enabling component in these systems, providing stable electric fields or pulsed excitation to multiple sensor modules, including X-ray transmission, nuclear magnetic resonance, optical scattering, microwave sensing, and chemical detection, ensuring precise and synchronized operation across modes.
The power supply must maintain extremely high voltage stability and fast response. Typical requirements include voltage precision within 0.01% and pulse response times in the nanosecond-to-microsecond range to ensure signal synchronization across all detection modules. Digital closed-loop control continuously monitors voltage and current, automatically correcting deviations in real time. Multi-channel independent regulation allows precise voltage allocation for each sensor, optimizing excitation conditions and improving detection sensitivity.
Data fusion is critical for enhancing system performance. Signals from various detection modes are collected into a unified digital processing platform. Fusion algorithms may include weighted averaging, Bayesian inference, feature-level integration, and deep learning models, exploiting complementary information from multiple sensors. Stable high-voltage output ensures consistency of data acquisition, minimizing errors caused by voltage fluctuation.
The power supply can also interact with the data fusion results to optimize system operation. If one mode shows interference or weak signal, the control system can automatically adjust the corresponding channel voltage to enhance response. Dynamic adjustment of voltage parameters based on environmental conditions or target properties further ensures high detection accuracy and rapid response. The combination of high-voltage precision and multi-mode data fusion significantly improves detection reliability and reduces false positives in explosive detection applications.
