Passenger Boarding Bridge Inspection Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for automatic inspection of passenger boarding bridges do not consider coordination with personnel, such as workers, which can lead to inefficiencies and safety concerns during the inspection process.
Innovation Solution
A system that includes a notifier and a controller to perform automatic inspections of passenger boarding bridges. The controller coordinates the inspection by performing operation tests on devices in a predetermined order, and the notifier provides operation test-related information to personnel both inside and outside the bridge, ensuring safe and efficient coordination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic inspection is performed without personnel coordination, then inspection efficiency is improved, but safety risks and operational coordination problems worsen
Solution Approach 1:
The system continuously monitors personnel presence during inspection and provides real-time feedback to the controller. When personnel are detected, the system automatically pauses the inspection and notifies relevant personnel, creating a closed-loop feedback mechanism that balances efficiency with safety coordination requirements
Solution Approach 2:
A notification device acts as an intermediary between the inspection system and personnel. This intermediary component communicates inspection status and personnel presence information to workers, enabling coordination without requiring direct human intervention in the automated inspection process
2Speed
If inspection starts immediately without personnel detection, then inspection speed is improved, but safety hazards increase
Solution Approach 1:
The system performs preliminary personnel detection before initiating the inspection sequence. The controller checks for personnel presence in advance and only starts the inspection after confirming the area is clear, preventing safety hazards before they can occur
Solution Approach 2:
The system takes preliminary anti-action by detecting personnel presence and automatically preventing inspection initiation or pausing ongoing inspection when personnel are detected, thereby counteracting potential safety hazards before they can manifest
3Productivity
If continuous inspection is performed without interruptions, then productivity is improved, but coordination with personnel deteriorates
Solution Approach 1:
The inspection system transitions from a static continuous operation mode to a dynamic mode that can pause and resume based on personnel presence. The controller dynamically adjusts inspection operation state in response to real-time personnel detection, enabling both continuity and coordination

AI summary
A system for performing an automatic inspection of a passenger boarding bridge. The passenger boarding bridge is connected to a terminal building, and includes a plurality of devices that are operatable. The system includes: a notifier provided on the passenger boarding bridge; and a controller configured to control each of the devices and the notifier. The controller is configured to: when an inspection start command is inputted to the controller, perform an operation test of each of the devices in a predetermined order to detect abnormality in each device; and during a period from when the inspection start command is inputted to the controller until the operation test of a last device among the devices is ended, cause the notifier to notify operation test-related information inside and/or outside the passenger boarding bridge.
