Mobile Inspection Body for Transport Vehicle Abnormalities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport facilities struggle to accurately grasp the state of transport vehicles experiencing abnormalities due to limited information exchange capabilities, particularly when communication systems fail, leading to difficulties in managing and restoring these vehicles efficiently.
Innovation Solution
Incorporating a mobile body with a state information acquisition device, such as a camera and microphone, to autonomously acquire and transmit detailed information about the transport vehicle's state to a management terminal, enabling remote monitoring and operation commands for restoration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a transport vehicle uses standard communication systems to exchange information with the controller, then information exchange is simple and reliable under normal conditions, but the controller cannot grasp abnormalities when communication systems fail or when the transport vehicle cannot detect certain abnormality types
Solution Approach 1:
The patent introduces a mobile body as an intermediary device that can physically approach the transport vehicle and acquire state information directly when communication systems fail. This intermediary bridges the gap between the transport vehicle and controller, enabling abnormality detection through alternative means (sensors on the mobile body) when the standard communication path is compromised.
2Measurement precision
If the manager needs to grasp the state of a transport vehicle with abnormality, then on-site inspection provides accurate information, but it requires the manager to travel to the site and increases response time
Solution Approach 1:
The mobile body autonomously performs the function of on-site inspection by approaching the transport vehicle with abnormality and acquiring state information using its own sensors. This self-service capability eliminates the need for manager intervention, providing accurate measurement precision while reducing response time since the mobile body can immediately navigate to the affected vehicle.
Solution Approach 2:
The patent replaces the mechanical system of manual on-site inspection (manager traveling to the site) with an automated mobile body equipped with sensors. This substitution maintains measurement precision through direct physical proximity to the transport vehicle while eliminating the time loss associated with human travel and manual inspection.
3Reliability
If the transport vehicle relies on its own sensors and communication system to detect abnormalities, then the system remains simple, but it cannot detect all types of abnormalities especially when communication fails
Solution Approach 1:
The patent applies local quality by having the mobile body provide enhanced monitoring capabilities specifically at locations where transport vehicles exhibit abnormalities. Instead of equipping every transport vehicle with comprehensive detection sensors (which would increase overall system complexity), the mobile body concentrates advanced sensing resources locally at problem areas, thereby improving abnormality detection coverage without proportionally increasing system-wide complexity.

AI summary
A transport facility includes a mobile body configured to move separately from a transport vehicle, a mobile body control system configured to control the mobile body, and a management terminal for a manager. In a case where an abnormality occurs in the transport vehicle, the mobile body control system performs an abnormality handling process of a state information acquisition device sequentially acquiring state information including a state of the transport vehicle in a state where the mobile body can acquire the state information by means of the state information acquisition device, and sequentially transmitting the acquired state information to the management terminal.
