This invention relates to the field of adversarial example defense in target detection, and discloses an adversarial example defense system and method based on image masking. The system includes a target detection and localization module, a key target extraction module, a key target image cropping module, a target mask processing module, an image mask processing module, an image classification module, and a weighted voting module. This method requires no modification to the target detector, only processing of the input image. This invention is widely compatible with existing target detectors, possesses good versatility, effectively enhances the target detection system's ability to resist adversarial example attacks, and comprehensively improves the system's robustness and security.

This invention relates to a high-voltage fast charging system and charging control method for electric commercial vehicles. The system includes: a charging interface for connecting to a charging pile to receive charging voltage; a high-voltage electrical component group; a battery pack assembly including two first battery pack units and two second battery pack units, wherein the voltage level of the first battery pack units is higher than that of the second battery pack units; a first switch group and a second switch group for switching the series-parallel connection mode between the first and second battery pack units, so that the battery pack assembly forms a first operating voltage in a first connection state and a second operating voltage higher than the first operating voltage in a second connection state; a third switch group for connecting the battery pack assembly to the charging interface; a pre-charging circuit for connecting the battery pack assembly to the high-voltage electrical component group; and a controller electrically connected to the first, third, and second switch groups for controlling the on / off state of each switch group according to the operating mode. Specifically, in discharge mode and normal charging mode, the first and second switch groups control the battery pack assembly in the first connection state; in high-voltage charging mode, the first and second switch groups control the battery pack assembly in the second connection state.
