Remote Elevator Rescue Control With Verified Elevator Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator rescue operations require manual intervention at the site, which can be time-consuming and inefficient, especially when passengers are trapped due to malfunctions.
Innovation Solution
A centralized remote operation system that verifies and controls multiple elevators using a remote service system, enabling secure and automated rescue operations by distinguishing the correct elevator through shared secrets, challenge-response authentication, and visual/audio signals, and performing operations like bypassing safety contacts and activating rescue drives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual rescue operation is performed locally at elevator site, then reliability of rescue operation is ensured, but loss of time increases due to serviceman arrival time
Solution Approach 1:
The patent replaces the mechanical system of physical presence (serviceman arriving on-site) with an automated control system. The elevator controller automatically executes rescue operations through programmed instructions, eliminating the need for manual intervention and reducing response time while maintaining operational reliability through automated safety protocols.
Solution Approach 2:
The elevator system performs self-rescue operations through its built-in controller and automated mechanisms. When a rescue condition is detected, the system autonomously executes the rescue sequence without requiring external human assistance, thereby eliminating the time delay associated with serviceman arrival while ensuring reliable operation through built-in safety systems.
2Productivity
If remote operation is implemented without verification, then productivity of rescue operation is improved, but reliability deteriorates due to incorrect elevator control
Solution Approach 1:
The patent implements a verification mechanism where the remote operation system receives feedback from the elevator controller to confirm identity before executing control commands. This feedback loop ensures that the correct elevator is identified and controlled, maintaining reliability while enabling rapid remote rescue operations through automated verification protocols.

AI summary
According to an aspect, there is provided a method for remote operation of a plurality of elevators in a centralized manner by a remote service system, the remote service system comprising a remote communication computer and wherein each of the plurality of elevators comprises an elevator controller associated with a communication computer. The method comprises receiving, by a remote service system from the communication computer associated with an elevator, a rescue request associated with the 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 communication computer, a data connection with the communication computer associated with the elevator to control the verified elevator; and performing, by the remote service system, at least one remote operation associated with the verified elevator using the enabled data connection.
