Remote Elevator Rescue Operation Through Verified Data Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator rescue operations are delayed due to the need for manual intervention by a serviceman, which can take time and is inefficient in addressing passenger emergencies.
Innovation Solution
A remote operation system allows centralized control of multiple elevators using a remote service system with a manual operation panel and communication computer, enabling verification and secure data connection to perform remote manual operations, including bypassing safety contacts and activating rescue drives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual rescue operation is performed locally at elevator site, then serviceman can directly rescue trapped passengers, but it takes time for serviceman to arrive at the site
Solution Approach 1:
A remote service system acts as an intermediary between the trapped passengers and the serviceman. The system includes a remote communication computer that establishes data connections with elevator controllers, allowing the serviceman to remotely verify elevator identity, control elevator operations, and perform rescue functions without physically traveling to the site. This mediator enables immediate rescue response while maintaining operational simplicity for the serviceman.
2Loss of time
If remote operation is implemented, then rescue time is reduced, but verification of correct elevator is needed to ensure safety
Solution Approach 1:
The remote service system implements a feedback mechanism where the serviceman can send verification challenges to the elevator and receive responses to confirm the correct elevator is selected. The system provides feedback signals between the remote operation panel and the elevator controller, enabling the serviceman to verify elevator identity through challenge-response authentication before initiating rescue operations. This feedback loop ensures safety while maintaining remote operation efficiency.
3Productivity
If remote manual operation is performed, then on-site personnel are not needed, but secure data connection and control must be established
Solution Approach 1:
The system performs preliminary actions by pre-establishing secure communication protocols and verification procedures before remote rescue operations begin. The remote communication computer pre-configures data connections with elevator controllers and implements preliminary verification of elevator identity. This preliminary setup ensures that when rescue operations are needed, the connection is already secure and authenticated, enabling immediate productive action without compromising reliability.

AI summary
According to an aspect, there is provided a method for remote operation of a plurality of elevators, each of the plurality of elevators being coupled with a communication computer. The method comprises receiving, by a remote service system from the communication computer, a rescue request associated with an elevator; providing, by the remote service system, a verification to distinguish the elevator associated with the rescue request among the plurality of elevators; enabling, by the remote service system, a data connection with the communication computer to control the verified elevator; and performing, by the remote service system, a remote operation associated with the verified elevator via the enabled data connection.
