Elevator Control System Automated Parameter Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator systems require manual site visits for setup runs to acquire operation parameters when data is lost, causing laborious and unplanned downtime.
Innovation Solution
A method for acquiring a new set of elevator operation parameters through automated or remote initiation of a setup run, ensuring data integrity is determined and pre-conditions are met, allowing the setup to be performed without physical site visits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual site visit is performed for setup run, then data acquisition can be completed, but labor cost and downtime increase
Solution Approach 1:
The elevator system automatically detects data integrity loss through checksum algorithms and autonomously initiates setup runs without requiring external intervention. The control system monitors itself, determines when re-acquisition is needed, and triggers the appropriate response actions automatically.
Solution Approach 2:
The patent replaces the mechanical/manual process of service technician site visits with an automated electronic control system that remotely monitors data integrity, detects losses, and autonomously initiates setup runs through electronic signaling to the elevator drive system.
2Ease of operation
If manual setup run is initiated, then operation parameters can be re-acquired, but service personnel deployment is required
Solution Approach 1:
The control system continuously monitors data integrity using checksum algorithms and provides feedback when data loss is detected. This feedback mechanism automatically triggers the setup run initiation process, creating a closed-loop system that responds to data integrity conditions without human intervention.
Solution Approach 2:
The patent introduces an intermediary automated control system that acts between the data storage system and the setup run execution. This intermediary monitors data integrity, makes determination decisions, and triggers setup runs, eliminating the need for direct human involvement while managing system complexity.
3Loss of information
If data integrity monitoring is implemented, then data loss can be detected, but system complexity increases
Solution Approach 1:
The patent implements data integrity monitoring by calculating and comparing checksum parameters of stored operation parameters. When the checksum changes indicating data corruption or loss, the system automatically detects the integrity issue and triggers appropriate responses without requiring complex monitoring infrastructure.

AI summary
A method for acquiring a new set of elevator operation parameters of an elevator (300). The method comprises determining (110) a loss of data integrity relative to a previous set of elevator operation parameters and checking (120) whether a set of pre-conditions for the acquiring are fulfilled, the set of pre-conditions comprising determining (122A) that an elevator car (10) of the elevator (300) is empty of persons, determining (122B) that an elevator shaft (12) of the elevator (300) is empty of persons, and determining (122C) that a safety system of the elevator (300) is operable. The method also comprises initiating (130) a setup run to be performed by utilizing the elevator car (10) for the acquiring of the new set.
