Elevator Controller Automated Commissioning Check Program
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator installations require complex and error-prone commissioning and acceptance checks due to individualized configurations, leading to potential oversight of necessary steps and documentation challenges, especially with varying legal standards and component specifics.
Innovation Solution
A method where configuration data stored in the elevator controller determines necessary check steps, generating a check program that guides the process through a menu-controlled sequence, ensuring all required inputs are made and comparisons between target and actual values are conducted, reducing human error and documentation needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional manual checking methods are used for elevator installations, then flexibility to handle individual configurations is maintained, but the complexity and error rate increase due to numerous decision choices and documentation requirements
Solution Approach 1:
The elevator controller performs self-diagnosis and self-guidance during commissioning and acceptance checking. The control unit automatically determines necessary check steps based on stored configuration data, generates check programs, and guides the operator through the process without requiring extensive manual documentation or decision-making about individual configuration requirements.
Solution Approach 2:
The patent replaces manual mechanical checking processes with an automated control system. The controller's processing unit electronically determines check steps, generates check programs, and manages the commissioning and acceptance checking process, substituting the need for manual documentation and physical checklists with digital automation.
2Reliability
If extensive documentation is maintained for individual elevator configurations, then completeness of checking is ensured, but the time and effort required for commissioning and acceptance checking increases
Solution Approach 1:
The elevator controller pre-stores configuration data and check procedures in its memory before the actual commissioning and acceptance checking occurs. This preliminary preparation of check programs and procedures eliminates the need for real-time documentation creation and reduces the time required during the actual checking process while ensuring complete and reliable verification.
Solution Approach 2:
The system creates digital copies of check procedures, configuration data, and verification steps within the controller's memory and display units. These electronic copies replace physical documentation, allowing the operator to access all necessary checking information instantly without handling extensive paper records, thereby reducing time while maintaining reliability.
3Manufacturing precision
If individualized checking measures are implemented for each elevator configuration, then accuracy of verification is improved, but the number of decision choices and potential errors increases
Solution Approach 1:
The control unit continuously monitors the commissioning and acceptance checking process, providing feedback to guide the operator through predetermined check steps based on the specific elevator configuration. This feedback mechanism ensures precise verification by automatically adjusting the check program according to stored configuration data, eliminating the need for complex manual decision-making while maintaining verification accuracy.

AI summary
A method of checking elevator installations with a car, an elevator drive and an elevator controller with a memory avoids or at least reduces errors by a person carrying out the check and enables convenient and reliable checking of the elevator installation. A check program including all steps necessary for the check is set up on the basis of stored configuration data of the elevator installation in the elevator controller and in dependence on a selected mode of operation. In addition, the steps are displayed in a predetennined sequence on an indicating and control unit and necessary inputs for working down the steps are input by way of the indicating and control unit.
