Crane Inspection Route Setting for Variable Posture and Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Setting a flight route for a moving body inspecting a crane is complex due to the crane's varying posture, assembly pattern, and direction, requiring users to identify and manually set the route during inspections.
Innovation Solution
A crane inspection system that includes a moving body with an imaging unit and a processing unit to perform inspections based on captured data, along with a route setting unit that sets the movement route based on the crane's structure, posture, position, and direction, using sensors and a management server to facilitate automatic route setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual route setting is used for crane inspection, then the inspection can be performed, but the operation complexity increases and user effort is required
Solution Approach 1:
The route setting unit automatically generates the inspection route by acquiring the crane's disposition state (structure, posture, position, direction) and computing an appropriate path, eliminating the need for manual route setting by users. The system serves itself by autonomously determining the inspection trajectory based on real-time crane parameters.
Solution Approach 2:
The system acquires the crane's disposition state information in advance before generating the inspection route. By obtaining structural, postural, positional, and directional data beforehand, the route setting unit can pre-compute an optimized inspection path without requiring manual intervention during the inspection process.
2Extent of automation
If automatic route setting is implemented, then user effort is reduced, but the system requires complex sensors and processing units
Solution Approach 1:
The route setting unit serves multiple functions: it acquires crane disposition state data, processes structural and postural information, determines optimal inspection routes, and outputs navigation guidance. This multi-functional component consolidates what would otherwise require separate systems, achieving automation without proportionally increasing overall system complexity.
Solution Approach 2:
The route setting unit acts as an intermediary between the crane's sensor data and the moving body's navigation system. It receives raw disposition state information from sensors, processes this data to determine appropriate inspection routes, and translates this into navigation commands for the moving body, simplifying the integration between detection and execution systems.
3Adaptability or versatility
If the moving body follows a fixed route, then the inspection process is simple, but it cannot adapt to varying crane postures and positions
Solution Approach 1:
The inspection route is dynamically generated based on the crane's current disposition state (structure, posture, position, direction). Rather than following a predetermined fixed path, the route setting unit continuously adapts the inspection trajectory to match the crane's actual configuration, ensuring comprehensive coverage while maintaining operational efficiency.
Solution Approach 2:
The system uses the acquired crane disposition state information as feedback to adjust and optimize the inspection route. By monitoring the crane's structural, postural, positional, and directional parameters, the route setting unit continuously refines the inspection path to adapt to varying crane configurations, balancing adaptability with inspection productivity.

AI summary
A crane inspection system includes a moving body including an imaging unit and moving around a crane, a processing unit configured to perform an inspecting process, based on imaging data captured by the imaging unit, and a route setting unit configured to set a movement route of the moving body during an inspection, based on a disposition state relating to at least one of a structure, a posture, a position, and a direction of the crane.
