Solution Overview

Problem

Current agricultural field management systems lack effective methods for real-time monitoring and response to dynamic movements of people, animals, and objects, and fail to prioritize urgent situations efficiently.

Innovation Solution

A system comprising communication devices with physical quantity detection circuits and outputting circuits that generate notification information, a dispatcher that receives and acts on this information to call a management machine, such as a multicopter, to address detected threats or emergencies, with a server and mobile terminal for communication and activation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical quantity detecting circuits are deployed throughout the field to enable real-time monitoring, then monitoring coverage and response capability are improved, but system complexity and cost increase

Engineering Contradiction:

Improvemonitoring reliabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The field is divided into multiple zones with communication devices distributed throughout, each detecting local physical quantities independently. This segmentation allows comprehensive coverage while keeping each individual device simple and manageable.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Communication devices perform multiple functions: detecting physical quantities, classifying danger levels, transmitting notifications, and coordinating with management machines. This multi-functionality reduces the need for separate specialized devices for each task.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Speed

If all notification information is transmitted immediately to the dispatcher, then response time is improved, but communication bandwidth consumption and information processing load increase

Engineering Contradiction:

Improvenotification speedVSAvoidcommunication energy consumption

Core Design Contradiction:

SpeedVSLoss of energy

Solution Approach 1:

Different notification information is treated differently based on its danger level classification. High-danger notifications are transmitted immediately with priority, while low-danger notifications may be buffered or transmitted with lower priority, optimizing communication resource usage.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system classifies physical quantity data into danger levels and provides feedback to the dispatcher about the urgency and nature of each notification, enabling intelligent routing and prioritization of communication resources.

Inventive Principle:

Principle #23Feedback

3Measurement precision

If the system monitors all physical quantities continuously, then detection accuracy is improved, but energy consumption by communication devices increases

Engineering Contradiction:

Improvephysical quantity detection accuracyVSAvoidcommunication device energy consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

Instead of continuous monitoring, the system uses periodic sampling of physical quantities combined with event-triggered transmission. Devices monitor continuously for accuracy but only transmit when changes exceed thresholds or danger levels are reached, reducing communication energy consumption.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system changes monitoring parameters dynamically based on conditions - adjusting sampling rates, threshold sensitivity, and transmission frequency according to the current state of the field and detected physical quantities, optimizing the balance between accuracy and energy consumption.

Inventive Principle:

Principle #35Parameter changes

AI summary

An agricultural field management system includes a plurality of communication devices arranged in an agricultural field and configured to detect a physical quantity indicating dynamic movement of objects, a dispatcher arranged in the agricultural field and configured to communicate with each of the communication devices, a management apparatus configured to move in the agricultural field. Each of the communication devices is configured to generate first notification information indicating a danger the communication devices, and second notification information indicating an emergency having a urgency degree higher than the danger of the first notification information to the communication devices, defer to transmit the second notification information to the dispatcher until receiving activation information from the dispatcher, and transmit the second notification information to the dispatcher upon receiving the activation information. The dispatcher moves the management apparatus to the communication devices which transmits the first notification information or the second notification information.
