AI Technical Summary

Technical Problem

After completing the spraying operation in the cargo yard, the robotic arm of the spraying robot often retracts asynchronously, causing the sprayed water jets to form complex nonlinear confluence effects in the air. This results in abnormal superposition of water flow energy and high-speed backflow, which damages the stability of the stack structure and affects the safety of port operations and the reliability of spraying control.

Method used

By constructing a unified event time baseline, collecting the attitude of the spraying robot arm, water pressure phase, and slope geometry parameters, generating a time-frequency geometric fusion map, identifying the energy core of the spray water jet convergence, constructing a backflow trigger index, optimizing the spraying robot arm retraction sequence, and deploying adaptive damping atomizers and variable vorticity nozzles to form an anti-phase backflow field, thus achieving closed-loop control.

Benefits of technology

It significantly improves the stability and safety of spraying operations, reduces the risk of damage to the pile structure, enhances the intelligence level of the spraying process, and provides reliable technical support for green and smart port operations.

Abstract

This invention discloses a method and system for optimizing port cargo spraying strategies applied to intelligent ecological robots, belonging to the field of intelligent robot control technology. The method includes: establishing a unified event time baseline; collecting the attitude parameters of the spraying robotic arm, water pressure phase parameters, and pile slope geometric parameters to generate a time-frequency geometric fusion map as a reference for abnormal energy identification; performing a phase traction test under the constraints of the time-frequency geometric fusion map, injecting time delay disturbances to measure the residual gradient field, and inferring the converging energy core of the spray water jets based on the residual gradient field. This invention achieves dynamic and stable control of the entire spraying process by constructing an event time baseline, identifying converging energy cores, optimizing the spraying retreat path, and combining reverse atomization weakening with time-phase control, thereby improving operational intelligence and safety and reducing the risk of pile damage.
