Movable Object Recovery Command Transmission for Faulty Transport Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport facilities face challenges in effectively recovering faulty transport vehicles due to communication failures, especially when the communication environment surrounding the transport vehicle is unfavorable.
Innovation Solution
A transport facility is designed with a movable object, including a communication device that can perform wireless communication with the transport vehicle, and a movable object controller that moves the movable object into the communication range of a faulty transport vehicle to transmit a recovery command.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a transport vehicle controller transmits a recovery command through distributed wireless transmitter-receivers, then the transport vehicle can be controlled remotely, but the recovery command may not be received due to unfavorable communication environment
Solution Approach 1:
A movable object equipped with a communication device serves as an intermediary between the transport vehicle controller and the faulty transport vehicle. The movable object transmits the recovery command directly to the transport vehicle, bypassing the unfavorable communication environment that affects the distributed wireless transmitter-receivers system.
2Area of stationary object
If multiple wireless transmitter-receivers are arranged in a distributed manner, then communication coverage is improved, but communication reliability deteriorates in certain locations due to environmental factors
Solution Approach 1:
The movable object dynamically moves to positions where it can establish reliable wireless communication with the faulty transport vehicle. Unlike fixed distributed transmitter-receivers, the movable object can adjust its location to avoid communication dead zones and unfavorable environments, ensuring reliable command transmission.

AI summary
A transport facility includes a transport vehicle that transports a transport article along a movement path, a movable object including a communication device that performs wireless communication with the transport vehicle being within a communication range and being movable separately from the transport vehicle, and a movable object controller that controls the movable object. The movable object controller causes, in response to determining that the transport vehicle is faulty, the movable object to be within the communication range of the transport vehicle and causes the communication device to transmit, to the transport vehicle, a recovery command for recovery of the transport vehicle.
