Transport Vehicle Abnormality Relay via Mobile Body Backup Link
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport facilities face challenges in properly ascertaining abnormalities in transport vehicles due to communication failures between the controller and the transport vehicle, which prevents timely notification to administrators.
Innovation Solution
A transport facility equipped with an information collection device in each transport vehicle and a mobile body that can acquire and transmit abnormality information independently of the primary communication system, allowing direct notification to an administrator terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication between the controller and transport vehicle is used to notify abnormalities, then the administrator can ascertain abnormalities when communication is functional, but abnormality notification fails when communication is faulty
Solution Approach 1:
A mobile body (portable device) acts as an intermediary to receive abnormality information directly from the transport vehicle's information collection device, bypassing the controller and communication system. This mediator approach ensures abnormality notification reliability even when the primary communication path fails.
Solution Approach 2:
The abnormality notification function is segmented into two independent paths: (1) the original path through the controller and communication system, and (2) a direct path from the information collection device to the mobile body. This segmentation allows the system to maintain notification capability through at least one path even when the other fails.
2Reliability
If a single communication path is used for abnormality notification, then the system structure is simple, but the notification fails when communication system malfunctions occur
Solution Approach 1:
The system changes the communication parameter by switching from exclusive reliance on wired/controller-based communication to include wireless direct communication with mobile bodies. This parameter change enables alternative notification paths when the original communication parameters (controller connectivity) fail.

AI summary
A transport facility includes an information collection device mounted in a transport vehicle, a mobile body that moves separately from the transport vehicle, and a communication system. The information collection device includes an abnormality information acquisition unit that acquires, in response to the occurrence of an abnormality in the transport vehicle, abnormality information including at least one of abnormality content information, pre-abnormality occurrence information, and post-abnormality occurrence information, and a first communication unit that transmits the abnormality information. The mobile body includes a second communication unit that communicates with the first communication unit and receives the abnormality information, not via the first communication system, and a third communication unit that gives an administrator terminal an abnormality occurrence notification, which is a notification of the occurrence of an abnormality.
