Elevator Operating Unit Address Assignment via Series Shift Registers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for setting up elevator systems with multiple floors require significant time and personnel to manually configure each operating unit, leading to high expenditure and potential errors.
Innovation Solution
A method where configuration data with address data packets is transmitted to operating units, allowing for automatic setup by storing addresses in shift registers connected in series, enabling each unit to be identified and verified for functionality, reducing manual intervention and error sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration of each operating unit is performed by a fitter, then each operating unit can be individually set up, but the time and personnel expenditure increase significantly
Solution Approach 1:
The operating units perform self-configuration by automatically receiving and storing address data from the control unit via the series connection, eliminating the need for manual setup by fitters and significantly reducing setup time while maintaining configuration accuracy
Solution Approach 2:
The manual mechanical configuration process is replaced by an automated electrical signaling system where the control unit transmits address data packets through the series-connected operating units, reducing both time and human resource requirements
2Reliability
If manual setup of operating units is performed, then configuration can be verified, but error sources increase due to manual intervention
Solution Approach 1:
The control unit automatically verifies configuration correctness by receiving feedback signals from operating units through the series connection, allowing automatic detection and verification of properly configured units without increasing overall system complexity
Solution Approach 2:
Operating units automatically confirm their own configuration status by transmitting check signals to the control unit, enabling self-verification without requiring manual intervention or complex verification procedures
3Productivity
If operating units are connected in series for automatic configuration, then setup time is reduced, but the system complexity increases
Solution Approach 1:
Multiple operating units are merged into a single series connection chain that shares common signal lines with the control unit, allowing simultaneous configuration of all units through one unified communication path rather than individual connections
Solution Approach 2:
The series connection serves multiple functions simultaneously: it provides the communication path for address data transmission, enables automatic configuration, allows verification of configuration status, and facilitates error detection, eliminating the need for separate configuration wires for each unit

AI summary
The invention relates to a method for setting up a number of operating units in a lift system having a number of floors. The operating units are connected in series. A first operating unit is connected to a central controller, and at least one operating unit is provided on each floor. Configuration data with an address data packet is sent from the controller to the operating units. The address data packet has a number of addresses, which permits the fixing of an address for each operating unit. The invention further relates to a lift system for carrying out the method.
