Processing Device for Control Target Area Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control technologies face challenges in precisely controlling control targets, such as shovels, when obstacles are misrecognized, leading to difficulties in accurately determining if the control target has entered a prohibited area.
Innovation Solution
A processing device and method that determine whether a control target has entered an unauthorized area by using a determination means and executing a predetermined process when the target is detected outside its allowed area, utilizing a combination of observation data and virtual environment simulation to accurately assess the control target's position and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control technologies are used to decelerate or stop an operation when the control target enters a prohibited area, then safety is improved, but measurement precision deteriorates when obstacles are misrecognized
Solution Approach 1:
The patent introduces a virtual environment as an intermediary layer between the physical control target and the detection system. By creating a virtual model of the control target and comparing it with observed data, the system achieves more accurate obstacle detection without compromising safety. The virtual environment acts as a mediator that refines the detection process and reduces misrecognition errors.
Solution Approach 2:
The patent creates a virtual copy (virtual environment) of the control target to compare with actual observation data. This virtual replica allows the system to detect obstacles more accurately by identifying discrepancies between the expected virtual state and actual observed state, thereby improving measurement precision while maintaining safety protocols.
2Productivity
If the control target is allowed to operate freely within its range, then productivity is improved, but reliability deteriorates when the control target enters prohibited areas
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously compares the virtual environment model with actual observation data to detect when the control target enters prohibited areas. This feedback loop allows the system to maintain high productivity by allowing free operation within safe zones while automatically intervening when boundaries are approached, thus balancing productivity with reliability.
Data Source
AI summary
A processing device determines whether or not a control target has entered an area other than an area that the control target is allowed to enter in an environment of a range including at least a part of the control target. The processing device executes a predetermined process when it is determined that the control target has entered an area other than the area that the control target is allowed to enter.
