Abstract

This invention provides a method for autonomous mobile navigation path planning in an ICU, relating to the field of path planning technology. The method includes: acquiring patient tags, task identifiers, and intervention records in an ICU disaster scenario; extracting task time series and analyzing frequency characteristics; filtering passage segments and matching time windows; identifying equipment overlap and operational conflicts; extracting remaining tasks to generate a scheduling sequence; rearranging path nodes and integrating task levels; and generating a navigation path segment sequence. In this invention, by extracting task time features and spatial states, priority task points are generated and passable paths are filtered. This adapts to the high density of ICU beds and path compression in disaster scenarios. Resource conflicts are identified by combining equipment usage records and node spatial relationships to avoid task overlap. A scheduling sequence is constructed based on task stagnation status, improving path adjustment efficiency and enhancing the robot's ability to respond to unexpected tasks and the continuity of path execution.
