Elevator Mobile Terminal Authentication Using Coded Light Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems pose safety risks during servicing due to the need for service personnel to enter the shaft or roof, and there is a lack of standardized safety measures to ensure safe entry and exit, particularly for less competent personnel.
Innovation Solution
A method using a mobile terminal to communicate with the elevator system via optical transmission of coded light signals, allowing secure authentication and position verification, enabling safe servicing and transition to normal operation without hazardous movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If service personnel enter the shaft or roof to service elevator components, then direct access to components is improved, but safety risks increase
Solution Approach 1:
The patent introduces an intermediary communication system between the mobile terminal and elevator control system. This intermediary layer enables service personnel to control the elevator car and access components remotely without physically entering the shaft or roof, thereby eliminating safety risks while maintaining ease of operation.
Solution Approach 2:
The patent replaces the mechanical approach of physically entering the shaft with an optical communication system. Light signals transmit authentication codes and control commands wirelessly between the mobile terminal and elevator system, substituting physical presence with optical signal transmission to eliminate safety hazards.
2Object-affected harmful factors
If complex check-in processes are implemented to ensure safety, then safety is improved, but ease of operation deteriorates
Solution Approach 1:
The mobile terminal automatically performs authentication by detecting light signals and exchanging data packets with the elevator control system. The system self-verifies safety conditions and grants access without requiring service personnel to manually complete complex check-in procedures, thereby improving safety while maintaining ease of operation.
Solution Approach 2:
The system performs preliminary authentication exchanges before allowing elevator car movement. The mobile terminal and control system exchange light signals and verify authentication codes in advance, ensuring safety conditions are met before service personnel can operate the elevator, thus simplifying the overall process while maintaining safety.
3Reliability
If optical communication is used for authentication, then security is improved, but device complexity increases
Solution Approach 1:
The patent utilizes the mobile terminal's existing camera and light detection capabilities for authentication, rather than requiring specialized hardware. The elevator control system's existing light indicators serve dual purposes: normal operation indicators and authentication signal transmission. This multi-functionality approach improves security while minimizing additional device complexity.

Implementation Method 1
generating a coded light signal by means of a control panel, which is arranged outside an elevator shaft of the elevator system, in response to this request
Implementation Method 2
detecting the coded light signal by means of the mobile terminal
Data Source
AI summary
A method for communicating with an elevator system utilizes a mobile terminal. The method includes steps of: sending a request from the mobile terminal to the elevator system or to an elevator controller of the elevator system; generating a coded light signal by a control panel that is arranged outside an elevator shaft in response to the request; detecting the coded light signal by the mobile terminal; sending a confirmation to the elevator system that the coded light signal has been detected; and authorizing the mobile terminal to communicate with the elevator system.
