Elevator Controller Adapter for Multi-Device Data Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional elevator arrangements often have a single data interface, limiting the ability to connect multiple data processing devices simultaneously, which can lead to interruptions in remote monitoring and maintenance procedures.
Innovation Solution
An adapter with multiple data interfaces and a data transmission selector that automatically establishes connections between the elevator controller and various data processing devices, such as maintenance tools, remote monitoring devices, and external controlling devices, based on signals from these devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single data interface is used in the elevator controller, then the device complexity is reduced, but the ability to connect multiple data processing devices simultaneously is limited
Solution Approach 1:
The adapter segments the data connection functionality by providing separate data interface units for different device types (maintenance tool interface, remote monitoring interface, external control interface), allowing each interface to be optimized for its specific function while sharing a common controller connection
Solution Approach 2:
The adapter acts as an intermediary device between the elevator controller and multiple data processing devices, translating and routing data transmissions between different interface protocols and the controller's single data interface
2Productivity
If manual reconnection is required when switching between maintenance tools and remote monitoring devices, then the device complexity is reduced, but the loss of time increases
Solution Approach 1:
The data transmission selector dynamically switches the active data interface connection based on which device is currently connected, automatically adapting the system configuration without requiring manual intervention
Solution Approach 2:
The system uses feedback signals from connected devices to automatically determine which data interface should be active, with the selector responding to presence/absence signals to switch connections appropriately
3Extent of automation
If manual switching between data interfaces is required, then the extent of automation is reduced, but the device complexity is reduced
Solution Approach 1:
The data transmission selector provides multi-functionality by automatically managing connections to multiple different device types (maintenance tools, remote monitoring devices, external control devices) through a single automated switching mechanism
Solution Approach 2:
The system performs self-service by automatically detecting which device is connected and switching the appropriate data interface without requiring manual configuration or intervention from operators

AI summary
An adapter for connecting an elevator controller to a variety of data processing devices includes a first remote side data interface unit configured for establishing a data connection to a first data processing device, a second remote side data interface unit configured for establishing a data connection to a second data processing device, a controller side data interface unit configured for establishing a data connection to the elevator controller, and a data transmission selector configured for selectively establishing a data transmission connection between the controller side data interface unit and one of the first and second remote side data interface units. The data transmission selector automatically selects the data transmission taking into account a signal which is signalized at the first remote side data interface unit.
