Predictive Baler Speed Control via Swath Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baler control systems are reactive and cannot effectively handle large fluctuations in swath size and density, leading to inefficiencies and potential clogging, especially when dealing with straw baled by a combine harvester, as they rely on costly and susceptible sensors for predictive control.
Innovation Solution
An automated system that maps and processes georeferenced data from the combine harvester to predictively control baler throughput, using GNSS, sensors, and machine parameters to adjust tractor speed based on swath characteristics, including moisture and density, to optimize baling efficiency and prevent clogging.

Engineering Contradiction Analysis
1Reliability
If sensors are used to record and characterize the swath in front of the tractor, then predictive control capability is improved, but cost and susceptibility to environmental influences increase
Solution Approach 1:
The patent uses a camera to capture optical images of the swath, creating a visual copy that can be processed to extract geometric information. This optical copy replaces the need for complex physical sensors that directly measure swath properties, reducing cost and environmental susceptibility while maintaining predictive control capability.
Solution Approach 2:
The patent replaces mechanical sensors with an optical system (camera) combined with image processing. This substitution eliminates the mechanical contact between sensors and the harsh agricultural environment, reducing susceptibility to dust and dirt while providing predictive swath information.

AI summary
A method and arrangement for controlling the speed of a baler (114) comprise the following steps or suitable means: recording and mapping at least one crop property and/or data derived therefrom during the harvesting of a field by means of a combine harvester (10) in which crop residues are deposited in a swath (64), and controlling the speed of the baler (114) when taking up the swath (64) taking into account the mapped crop property and/or the data derived therefrom.
