Remote Inspection of Moving Objects With Auxiliary Fault Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inspection systems for moving objects under unmanned driving cannot accurately determine whether detected abnormalities are due to the vehicle, the inspection device, or the server, leading to unclear causes for issues.
Innovation Solution
An inspection method involving a server instructing a moving object to achieve a predetermined output value, measuring this value using an inspection device, and conducting auxiliary inspections with a normal object to differentiate between the object, device, and server as the cause of abnormalities, allowing for precise determination of the abnormality's source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If inspection is conducted using a single moving object, then inspection time is reduced, but the ability to determine the cause of abnormality deteriorates
Solution Approach 1:
The inspection process is segmented into three distinct stages: initial inspection of the target moving object, auxiliary inspection of a normal moving object to verify server functionality, and subsequent inspection of multiple moving objects to confirm inspection device accuracy. This segmentation allows efficient use of time while systematically determining abnormality causes through progressive elimination of potential sources.
2Measurement precision
If auxiliary inspection with normal moving object is performed, then the ability to identify server-related abnormalities is improved, but inspection complexity increases
Solution Approach 1:
A normal moving object serves as an intermediary test subject between the target moving object and the inspection system. By inspecting this intermediary normal object, the system can determine whether the server is functioning correctly, thereby isolating server-related issues from target object abnormalities without requiring complex additional equipment.
3Measurement precision
If subsequent inspection with multiple moving objects is conducted, then the ability to identify inspection device abnormalities is improved, but inspection time increases
Solution Approach 1:
The auxiliary inspection of a normal moving object is performed preliminarily before the subsequent inspection of multiple moving objects. This preliminary action establishes a baseline by confirming server functionality, which allows the subsequent multi-object inspection to focus specifically on identifying inspection device abnormalities, thereby reducing overall inspection time while maintaining high determination accuracy.

AI summary
An method of inspecting a moving object movable by remote control includes: a first step of giving an instruction from a server to a moving object as an inspection target to drive the moving object so that an output value relating to moving of the moving object becomes a predetermined target value; a second step of acquiring a measured output value from inspection on the moving object; an auxiliary inspection step of performing the first and second steps on a normal moving object different from the moving object as the inspection target and about which the output value is normal when a difference between the target and measured values is not within a predetermined first range; and a third step of outputting information indicating an abnormality in the server when the difference between the target and measured values is outside a predetermined second range in the normal moving object.
