Excavation Control Using External Target Detection for Blind Spots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing excavation systems face challenges in detecting objects in blind spots and maintaining clear camera images due to machine shaking, leading to potential inaccuracies and decreased work efficiency.
Innovation Solution
An excavation system comprising a detection device installed at the excavation spot to gather information about the object's position, which is then used by a control device to transmit control information to the excavation device for precise operations, improving work efficiency by avoiding blind spots and reducing camera blur issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a camera is attached to the work machine to acquire the shape of the excavation target, then the system achieves remote control or self-control, but captured images are limited to what can be obtained from the work machine position, making it difficult to detect objects in blind spots
Solution Approach 1:
The patent introduces a separate detection device (camera or LiDAR) positioned at the excavation spot as an intermediary between the work machine and the control system. This detection device captures target location data independently of the work machine's position, providing comprehensive detection coverage including blind spots while enabling remote control functionality.
2Extent of automation
If a camera is attached to the work machine, then the system can operate remotely, but camera images become blurry due to shaking or movement of the work machine, reducing accuracy
Solution Approach 1:
The patent extracts the detection function from the work machine by positioning the detection device separately at the excavation spot. This separation eliminates the negative impact of work machine shaking on image quality, as the detection device remains stationary and stable while the work machine operates remotely.
3Ease of operation
If camera images are used for excavation control, then the system can function with remote operation, but image blur from machine movement degrades work efficiency
Solution Approach 1:
By introducing a stationary detection device at the excavation spot as an intermediary, the system maintains easy remote operation while eliminating image blur issues. The detection device provides stable, clear target location data regardless of work machine movement, thereby maintaining high work efficiency.
