Security Gate Control for Consecutive Mobile Robot Passage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control systems for multiple autonomous mobile robots struggle to efficiently manage the passage through security gates, leading to inefficiencies and potential delays in delivery operations.
Innovation Solution
A control system that allows multiple mobile robots to consecutively pass through a security gate by receiving and managing passing-through reservation signals, determining the order based on priority, and controlling the gate's opening and closing based on completion signals, ensuring efficient and coordinated movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the security gate opens once for multiple mobile robots, then the delivery efficiency is improved, but the control complexity increases
Solution Approach 1:
The control system receives passing-through reservation signals from multiple mobile robots in advance before they reach the security gate. This preliminary reservation allows the system to plan and coordinate the gate opening sequence ahead of time, enabling multiple robots to pass through efficiently during a single gate opening cycle without causing control chaos at the gate itself.
Solution Approach 2:
The system uses passing-through completion signals from mobile robots as feedback to track which robots have successfully passed through the security gate. This feedback mechanism allows the control system to manage the gate opening duration appropriately and determine when to close the gate, thereby simplifying the control logic despite multiple robots passing through.
2Loss of time
If multiple mobile robots pass through the security gate consecutively, then the waiting time is reduced, but the risk of collision or disorder increases
Solution Approach 1:
Mobile robots transmit their passing-through reservation signals in advance when they are still at a distance from the security gate. This preliminary action allows the control system to establish the passing sequence before robots arrive, ensuring orderly consecutive passage through the gate without collisions or disordered movement.
3Productivity
If the security gate remains open for multiple robots, then the throughput increases, but the security control is weakened
Solution Approach 1:
The control system receives passing-through completion signals from mobile robots as they exit the security gate area. This feedback allows the system to track which robots have successfully passed and to close the gate at the appropriate time, thereby maintaining security control while allowing multiple robots to pass through during a single opening cycle.

AI summary
A control system that controls opening-closing of a security gate which is provided in a facility in which a plurality of mobile robots travels autonomously is provided. The control system performs: receiving a passing-through reservation signal for passing through the security gate; and allowing a plurality of mobile robots to consecutively pass through the security gate while the security gate opens its gate once when passing-through reservation signals are received from the plurality of mobile robots.
