AI Technical Summary

Technical Problem

Existing technologies lack autonomous and efficient collaborative control mechanisms in distributed farmland operations, and cannot resolve conflicts in the real-time and spatiotemporal needs of multiple edge agents for shared resources in a timely manner, resulting in the loss of system collaboration capabilities or improper conflict resolution.

Method used

By adopting a distributed arbitration rule based on resource tokens, a consistent collaborative operation sequence table is generated through negotiation and evaluation among edge intelligent agent nodes. Combined with dynamic priority calibration and lightweight coding format negotiation messages, autonomous negotiation and decision-making are achieved, ensuring the robustness and security of the system.

Benefits of technology

It enables edge node groups to work autonomously and collaboratively without centralized cloud scheduling, improving system availability and robustness, reducing on-site operational risks, optimizing overall system efficiency, and possessing self-evolution capabilities.

Abstract

This invention relates to a precision variable fertilization control system for farmland based on intelligent agents and edge computing, applied in the field of smart agriculture. The system includes a cloud-based model management unit, multiple edge intelligent agent nodes, a variable fertilization execution mechanism, and a human-machine collaborative interaction terminal. Multiple edge intelligent agent nodes collaborate based on distributed arbitration rules to resolve operational conflicts related to shared agricultural resources. This rule uses resource token management as its core mechanism. When spatiotemporal conflicts arise between nodes regarding resource demands, they exchange negotiation messages containing token status, resource demands, and benefit values. Each node independently runs the arbitration algorithm, reaches a consensus, and generates a collaborative operation sequence table as a scheduling credential, thereby driving the execution mechanism. This invention fills the technological gap in autonomous collaborative rules at the physical execution layer of distributed agricultural equipment, achieving decentralized, highly robust, and highly secure precision variable fertilization operations.
