Elevator Door Commissioning via Sensor Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current elevator commissioning processes are complex, time-consuming, and labor-intensive, particularly in high-rise buildings, where environmental factors like 'Stack Effect' can adversely affect elevator door operations, leading to deviations from design requirements.
Innovation Solution
A method and system for commissioning elevators that involve obtaining operation data, comparing it with criterion data, and triggering controls to adjust elevator door operations to maintain pre-set ranges, thereby ensuring normal operation, which includes forming reports and transmitting them to monitoring platforms for analysis and control adjustments.

1Productivity
If traditional manual commissioning methods are used for elevator doors, then commissioning can be completed with simple equipment, but the process becomes extremely time-consuming and labor-intensive
Solution Approach 1:
The system enables self-service commissioning by automatically collecting door operation data through sensors, comparing it with criterion data, and adjusting control parameters without manual intervention. The elevator door system commissions itself by autonomously identifying deviations and correcting operational parameters.
Solution Approach 2:
Manual mechanical commissioning processes are replaced with an automated electronic system that uses sensors to collect data, processors to analyze deviations, and controllers to adjust parameters. This substitution of mechanical/manual operations with electronic automation dramatically reduces commissioning time and labor requirements.
2Reliability
If elevator doors in high-rise buildings operate continuously under environmental factors like Stack Effect, then the system remains simple initially, but deviations from design requirements accumulate over time
Solution Approach 1:
The system continuously monitors door operation parameters through sensors and compares real-time data with criterion operation data. When deviations are detected, the system automatically adjusts control parameters to correct the deviations, creating a closed-loop feedback mechanism that maintains precision despite continuous operation and environmental variations.
Solution Approach 2:
The commissioning system transitions from a static initial setup to a dynamic adaptive process. Control parameters are no longer fixed but are continuously adjusted based on real-time operational data and environmental conditions, allowing the system to adapt to changing conditions in high-rise buildings while maintaining operational precision.
3Manufacturing precision
If comprehensive monitoring and adjustment systems are implemented for elevator doors, then operation precision is maintained, but system complexity increases
Solution Approach 1:
The system uses multi-functional components that perform multiple tasks: sensors both monitor operation parameters and detect deviations, the processor both analyzes data and determines control adjustments, and the controller both receives commands and adjusts parameters. This multi-functionality reduces the need for separate dedicated components for each function, thereby limiting complexity growth.

AI summary
The present invention relates to a method and a system of commissioning elevator, and an elevator system. The method includes obtaining at least one operation data of at least one elevator door, comparing the operation data with corresponding criterion operation data, and determining whether a deviation between the operation data and the criterion operation data exceeds a pre-set range, and if so, triggering a control over at least one control end relevant to the operation of the elevator door to make a deviation between the operation data re-obtained and the criterion operation data fall within the pre-set range. The invention will increase the efficiency in elevator commissioning and remove the adverse effects on elevator operation caused by factors such as “Stack Effect”, and thereby ensure good working condition and high security of elevators.
