Automated Elevator Device Commissioning via Identity Challenge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The commissioning of new or reconfiguration of existing peripheral devices in transportation infrastructure control networks, such as elevators and escalators, is complex and often requires pre-configuration or on-site expertise due to the need for network connectivity and access rights management, especially in limited access spaces like elevator shafts.
Innovation Solution
A method and system for commissioning elevator and escalator peripheral devices in a transportation infrastructure control network that allows devices to be added or reconfigured without pre-configuration, using identity requests, access challenges, and access grants, enabling devices to connect directly to a network element or controller and send service requests, thereby simplifying the process and eliminating the need for on-site expertise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated network technologies are used for transportation infrastructure, then reliability of safety and control message transmission is improved, but device complexity and configuration difficulty increase
Solution Approach 1:
The commissioning process is segmented into distinct phases: identity request, access challenge, and access grant. Each phase handles a specific aspect of device integration, allowing complex network commissioning to be broken down into manageable, automated steps that maintain reliability while reducing configuration complexity.
Solution Approach 2:
The system performs preliminary actions by pre-establishing identity verification and access control mechanisms before actual device commissioning. The automated commissioning process prepares the network environment in advance, so that when a new device connects, the complex authentication and configuration steps are already structured and ready to execute automatically.
2Ease of operation
If pre-configured devices are used to simplify commissioning, then ease of operation is improved, but adaptability to changing building networks deteriorates
Solution Approach 1:
The commissioning system is designed to be dynamic rather than static. Instead of relying on fixed pre-configuration, the system adapts its commissioning process based on the actual network state, device identity, and access requirements. This allows the same automated process to work across different building networks and configurations.
Solution Approach 2:
The device performs self-service during commissioning by automatically responding to identity requests and access challenges. The automated commissioning process enables devices to configure themselves without external intervention, maintaining ease of operation while adapting to various network environments through the standardized challenge-response protocol.
3Measurement precision
If specialized expertise is required for device installation in limited access spaces, then measurement precision and configuration accuracy are improved, but productivity and ease of operation deteriorate
Solution Approach 1:
The device performs self-service during commissioning by automatically responding to identity requests and access challenges. The automated commissioning process enables devices to configure themselves without external intervention, maintaining ease of operation while adapting to various network environments through the standardized challenge-response protocol.
Solution Approach 2:
The automated commissioning process incorporates feedback mechanisms where the network element provides identity requests and access challenges, and the peripheral device responds accordingly. This feedback loop ensures configuration accuracy is maintained through automated verification while eliminating the need for specialized manual configuration in hard-to-reach locations.

AI summary
Commissioning of a transportation infrastructure peripheral device in a transportation infrastructure control network is disclosed. In the arrangement a peripheral device is attached to a transportation infrastructure control network through a network element or directly to a controller. When the connection has been made, a process for identifying and granting appropriate access rights is initiated. As a result, common network technologies can be used for transmitting information that is critical for elevator operation.
