Transporter Vibration Inspection Mode for Accurate Abnormality Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport facilities struggle to accurately determine abnormalities in transporters due to interference from vibrations generated by other transporters, leading to inaccurate detection of abnormalities in the target transporter.
Innovation Solution
A transport facility with a determination system that includes vibration detectors, recorders, and controllers to detect and analyze vibrations from individual transporters, allowing for an inspection mode where other transporters are stopped to isolate the target transporter's vibrations, improving data accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple transporters operate simultaneously to maintain productivity, then productivity is improved, but measurement precision of vibration data deteriorates due to interference from other transporters
Solution Approach 1:
The inspection is divided into two distinct modes: normal operation mode where multiple transporters operate simultaneously for productivity, and inspection mode where only the target transporter operates for accurate measurement. This segmentation allows both productivity and measurement precision to be optimized in their respective contexts
Solution Approach 2:
The system periodically switches between normal operation and inspection modes. During scheduled inspection periods, other transporters are stopped to enable accurate vibration measurement of the target transporter, while maintaining high productivity during normal operation periods
2Productivity
If vibration detection is performed during normal operation, then productivity is maintained, but reliability of abnormality detection deteriorates due to vibration interference
Solution Approach 1:
The system dynamically adjusts the operational state of transporters based on the inspection phase. During vibration inspection, the target transporter operates while others are stopped, creating a controlled dynamic environment that isolates vibration sources and improves detection reliability
3Ease of operation
If all transporters operate during inspection, then ease of operation is improved, but object-affected harmful factors increase due to vibration interference
Solution Approach 1:
The harmful vibration interference from non-target transporters is extracted from the measurement environment by stopping those transporters during inspection. This isolates the vibration sources to only the target transporter, eliminating interference while maintaining ease of operation through automated control

AI summary
A transport facility includes a plurality of transporters and a determination system. The determination system includes a vibration detector, a recorder, a determiner, and a controller. The vibration detector detects vibrations from each of the plurality of transporters and obtains vibration data indicating the vibrations. The recorder stores at least reference data for determination of a state of each of the plurality of transporters. The determiner determines a sign of an abnormality in each of the plurality of transporters based on the reference data stored in the recorder and the vibration data obtained by the vibration detector. The controller implements an inspection mode of stopping operations of the plurality of transporters other than a target transporter and obtaining, with the vibration detector, the vibration data of the target transporter in operation.
