Agricultural Work Management System for Real-Time Crop Quality Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural work management systems cannot effectively associate and evaluate the quality of crops, such as rice and wheat, with their harvesting position and yield data in real-time, limiting efficient agricultural administration.
Innovation Solution
An agricultural work management system that includes a data input unit for receiving harvesting position, yield, and quality data from crop harvesters, a database server for storing and associating this information, and an evaluation unit for generating and sending agricultural work evaluation data, allowing for real-time evaluation of crop quality and yield at the harvesting position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If quality data measurement is added to the harvester, then crop quality evaluation capability is improved, but device complexity increases
Solution Approach 1:
The quality measurement function is nested within the existing harvester control system. The quality data measurement unit integrates with the harvester's controller, which already handles positioning and yield measurement. This nesting approach allows quality evaluation capability to be added without creating a completely separate system, thereby improving measurement precision while minimizing the increase in device complexity.
Solution Approach 2:
The harvester controller is designed to perform multiple functions: positioning data acquisition, yield measurement, and quality data measurement. By making the controller universal and multi-functional, the system avoids adding separate dedicated hardware for each function, thus improving crop quality evaluation capability while keeping the overall device complexity manageable through shared resources.
2Productivity
If real-time data transmission is implemented, then agricultural administration efficiency is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous real-time transmission, the system implements periodic data transmission at predetermined time intervals. The controller transmits positioning data, yield data, and quality data to the server at scheduled intervals, which maintains agricultural administration efficiency by providing regular updates while significantly reducing energy consumption compared to continuous transmission.
3Loss of information
If multiple data types are collected and stored, then data association capability is improved, but information storage requirements increase
Solution Approach 1:
The system merges multiple data types (positioning data, yield data, quality data) into a unified database structure on the server. By combining these related data elements into an integrated storage system with proper associations, the system improves data association capability while optimizing storage efficiency through consolidated data management rather than separate storage for each data type.

AI summary
An agricultural work management system includes: a data input unit configured to receive, from an agricultural crop harvester, harvesting position data indicating a harvesting work position as agricultural land information, harvest amount data indicating a harvest amount of the agricultural crop harvested in the agricultural land, and quality data indicating the quality thereof as agricultural crop information; a database server configured to store the agricultural land information and the agricultural crop information such that they can be associated with each other; an agricultural work evaluation unit configured to perform agricultural work evaluation on the agricultural land based on the agricultural land information and the agricultural crop information; and a data output unit configured to send out the agricultural work evaluation data generated by the agricultural work evaluation unit.
