AI Technical Summary

Technical Problem

The communication linkage between drones and smart turnover cabinets suffers from coarse-grained collaboration and poor adaptability of communication links in complex environments, making it difficult to guarantee the accuracy of cargo handover and operational safety, and failing to meet the requirements of high-reliability collaborative operations.

Method used

By calculating the real-time straight-line distance between the drone and the intelligent turnover cabinet, the system performs coordinated scheduling in stages, collects electromagnetic interference parameters in real time, dynamically adjusts the modulation coding method and transmission power, monitors the packet loss rate and retransmission count, and automatically switches frequency bands to rebuild the connection when the link quality deteriorates, while continuously monitoring the door status and hovering positioning accuracy.

Benefits of technology

It significantly improves the reliability and environmental adaptability of drones and turnover containers working together, shortens response delays, ensures the safety and timeliness of cargo handover, and prevents damage or collision accidents caused by the hatch not being in place or positioning deviation.

Abstract

This invention belongs to the field of logistics signal processing, and particularly relates to a communication linkage scheduling method for logistics drones and intelligent turnover cabinets. The method includes: calculating the real-time straight-line distance between the drone and the intelligent turnover cabinet; establishing a two-way communication link and acquiring the real-time status of the cabinet when the distance is less than or equal to a first preset threshold; performing phased scheduling based on the distance range, sending an approach warning signal when the distance is far, and sending a door opening command when the distance is close, and issuing a hovering positioning signal after confirming that the door is fully opened; during the linkage process, collecting interference parameters such as electromagnetic interference intensity in real time, dynamically adjusting the modulation coding method and transmission power, and monitoring the packet loss rate and retransmission count; when the threshold is exceeded, reselecting a frequency band to rebuild the link; in the second stage of scheduling, continuously monitoring the door status and hovering positioning accuracy; when both conditions are met, generating a cargo handover permission signal to trigger a delivery or retrieval action; this invention improves the reliability and environmental adaptability of the collaborative operation between the drone and the turnover cabinet.
