The application discloses a kind of man-machine interaction risk prediction and adaptive safety avoidance methods, systems and media for automatic plant vehicle, first through multi-source sensing synchronous acquisition plant vehicle working condition and plant environment data, rely on pre-constructed plant semantic map matching pedestrian space attribute;Solving motion parameters to pedestrian multi-frame tracking, generate multi-probability prediction trajectory in combination with plant topology;Again, segmentation sensor occlusion area, infer potential pedestrian risk in blind area based on multi-feature Sigmoid model;Fusion explicit pedestrian, blind area pedestrian, plant semantic component constructs space-time man-machine interaction risk field;In combination with vehicle speed, load, trajectory uncertainty Real-time generation dynamic safety zone;According to risk overlap index Implementation four-level hierarchical control, and supporting sensor abnormality three-level safety degradation strategy.The application breaks through the defect of traditional fixed safety threshold, only passive obstacle avoidance, can predict pedestrian multiple motion behaviors in advance, early warning blind area sudden pedestrian risk, applicable to AGV, unmanned fork truck and other man-machine mixed plant scene.

This invention relates to a method and system for treating interface contaminants in a mixing and clarification tank, belonging to the field of nuclear fuel reprocessing. The method involves conveying interface contaminants to the final stage mixing and clarification tank via top-tank operation, separating the organic phase, and then returning the liquid containing interface contaminants from the final stage mixing and clarification tank to the organic phase inlet of the first stage mixing and clarification tank. The interface contaminants are dispersed by the agitation of the pump impeller within the mixing and clarification tank, thereby redissolving radioactive materials in the liquid. This invention utilizes in-situ treatment of interface contaminants and recovery of radioactive elements in a mixing and clarification tank, significantly reducing the accumulation of radioactivity in interface contaminants, mitigating radiation damage from organic solvents, and is simple to operate without requiring additional treatment equipment.

The application provides a signal timing and networked automatic driving vehicle speed hierarchical collaborative control method based on reinforcement learning, and relates to the technical field of intelligent traffic control and vehicle-road collaborative control, and comprises the following steps: obtaining the stop-and-drive vehicle state information on the import lane served by each phase at each signal cycle boundary, and generating a reference timing scheme of the next cycle by a cycle timing intelligent agent based on the stop-and-drive vehicle state information; obtaining a refined discharge window; and outputting a continuous longitudinal acceleration control instruction to a target networked automatic driving vehicle by a networked automatic driving vehicle speed intelligent agent according to the refined discharge window, so that the arrival time of the target networked automatic driving vehicle matches the discharge window, and the collaborative control of traffic signal timing and vehicle speed is realized.
