Elevator Controller Robot Interlocking Control Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing elevator systems lack effective countermeasures for failure modes during the robot boarding and alighting procedures, leading to delays in passenger services and reduced service quality.
Innovation Solution
A robot interlocking elevator control system that includes an autonomous vehicle and an elevator controller, which communicates with the autonomous vehicle to manage the elevator door opening and closing, and sets specific standby times and door control settings based on shared or exclusive elevator modes to handle failure modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the elevator controller disables the door close button and maintains door opening restriction during robot boarding/alighting procedures, then robot safety is improved, but passenger service is delayed and service quality deteriorates when failures occur
Solution Approach 1:
The patent segments the elevator service into two distinct modes: robot-exclusive mode and shared mode. In robot-exclusive mode, the door close button is disabled and door opening restriction is maintained throughout the robot's boarding and alighting procedures. In shared mode, the door close button remains enabled and door opening restriction is released, allowing normal passenger service to continue even when a robot is present. This segmentation resolves the contradiction by allowing robot safety to be prioritized when the elevator is dedicated to robot service, while maintaining passenger service efficiency when both robots and passengers share the elevator.
2Reliability
If the elevator maintains door opening restriction until robot boarding/alighting is complete, then robot safety is improved, but service quality and operation efficiency deteriorate due to delays
Solution Approach 1:
The patent dynamically adjusts the door opening restriction and door close button enabled/disabled states based on the elevator's operational mode and the current step in the robot boarding/alighting procedure. In robot-exclusive mode, the system maintains door opening restriction and disables the door close button throughout the procedure. In shared mode, the system releases door opening restriction and enables the door close button, allowing dynamic response to passenger needs while still providing robot safety when appropriate.
3Productivity
If the elevator controller releases door opening restriction and enables door close button in shared mode, then passenger service efficiency is improved, but robot safety may be compromised
Solution Approach 1:
The patent applies different control qualities to different operational contexts. In robot-exclusive mode, the door close button is disabled and door opening restriction is maintained, providing high-level robot safety protection. In shared mode, the door close button is enabled and door opening restriction is released, prioritizing passenger service efficiency. The system locally adapts the safety measures to match the operational context, ensuring robot safety when the elevator is dedicated to robot service while maintaining efficient passenger service when both robots and passengers share the elevator.

AI summary
Disclosed is a robot interlocking elevator control system. The robot interlocking elevator control system provides countermeasures against failure modes in a boarding/alighting procedure of a robot with respect to an elevator for movement between floors in a building, thereby achieving significant improvement in overall service quality and operation efficiency of an elevator system controlled in conjunction with the robot without delay of a passenger service.
