Shovel Control for Continuous Person-Position Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional object detection systems for shovels, such as those using stereo cameras, may fail to accurately detect objects in certain environments, potentially compromising safety by not continuously displaying the presence of individuals when they are no longer detected.
Innovation Solution
A system that includes an imaging device and a controller to continuously display the position of a person around the shovel even when the person is no longer detected by the imaging device, under predetermined conditions, using a trained model to estimate and maintain the position of the person on the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional object detection systems (e.g., stereo cameras) are used to detect objects around the shovel, then the system structure is relatively simple, but the detection accuracy deteriorates in certain environments leading to safety compromises
Solution Approach 1:
The patent combines multiple detection approaches (imaging device detection and continuous display based on predetermined conditions) into a unified safety monitoring system. This integration allows the system to maintain simplicity while improving detection reliability by compensating for individual detection failures through the continuous display mechanism.
Solution Approach 2:
The system implements a continuous display function that maintains object position information even when detection is temporarily lost. This beforehand cushioning ensures that safety information is not abruptly lost when detection fails due to environmental factors, providing a buffer against detection inaccuracies without requiring more complex detection hardware.
2Reliability
If the imaging device stops displaying when a person is no longer detected, then the display information is kept current and accurate, but safety is compromised by not accounting for detection errors and environmental limitations
Solution Approach 1:
The system continuously monitors detection status and adjusts display behavior based on predetermined conditions. When detection is temporarily lost but conditions suggest the object may still be present, the system maintains the display, providing feedback-based safety assurance that accounts for detection limitations without permanently retaining outdated information.
Solution Approach 2:
The display system dynamically adjusts its behavior based on detection results and predetermined conditions. Rather than a static on/off display approach, the system flexibly maintains or updates position information based on real-time detection quality and environmental context, optimizing both reliability and information accuracy.

AI summary
A shovel includes a lower traveling body; an upper turning body turnably mounted on the lower traveling body; an imaging device attached to the upper turning body; a display device; and circuitry configured to display, on the display device, position information representing a relationship between positions of a person detected by the imaging device and the shovel and when the person whose position is represented in the position information is no longer detected by the imaging device, continue to display the position of the person who is no longer detected in the position information in a case where a predetermined condition is satisfied.
