AGV Path Guide Reconnection Using Multi-Angle Sensor Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated guided vehicles (AGVs) deviate from their path guides due to damage, leading to accidents and prolonged process delays, as conventional systems only generate alarms after significant deviation, causing congestion and inefficiencies.
Innovation Solution
The AGV is equipped with a guide sensor that performs first and second scanning operations at predetermined angles to detect the path guide, adjusting its direction and speed to return to the path if not detected, using bit sensors to determine path guide presence and enabling stable driving in complex environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the AGV waits for a certain time before generating an alarm after deviation, then false alarms are reduced, but the response time is prolonged and productivity decreases
Solution Approach 1:
The system performs preliminary scanning actions by rotating the AGV at predetermined angles and using guide sensors to detect the path guide before significant deviation occurs. This early detection mechanism allows the system to take corrective action before the deviation becomes critical, resolving the contradiction by enabling timely response without requiring prolonged waiting periods
Solution Approach 2:
The system continuously monitors path guide detection status through guide sensors and provides real-time feedback. When deviation is detected, the system immediately generates feedback signals to adjust the driving direction and return to the path guide, eliminating the need for prolonged waiting periods while maintaining reliable detection
2Measurement precision
If the AGV performs extensive scanning at multiple angles to detect path guide, then detection accuracy is improved, but the time required for scanning increases
Solution Approach 1:
The scanning process is segmented into discrete rotational steps at predetermined angles. Instead of continuous scanning, the AGV rotates to specific angles and performs detection at each segment, which reduces total scanning time while maintaining detection accuracy through strategic angle selection
Solution Approach 2:
The system performs scanning at predetermined angles that may exceed the minimum required detection range. This excessive action ensures comprehensive path guide detection accuracy while the predetermined nature of the angles optimizes the scanning process to minimize time loss

AI summary
A driving method of an automated guided vehicle including a guide sensor and moving along a path guide, includes first scanning the path guide, while rotating at a first set angle, determining whether the path guide is detected during the first scanning, and if the path guide is not detected in the first scanning, performing a second scanning of the path guide while rotating at a second set angle.
