Remote Elevator Control Authentication for Multi-Building Robot Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Developing a protocol or program for each building to connect robots to elevator systems creates an inefficient environment, and direct robot control over elevators can also lead to inefficiencies.
Innovation Solution
A standardized elevator control system using a database and processor to manage elevator control requests, with identification numbers for different layers of buildings and elevators, enabling efficient site-specific program development and authentication for elevator control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a protocol or program is developed for each building to connect robots to elevator systems, then robot-elevator connectivity is achieved, but system complexity and development inefficiency increase
Solution Approach 1:
The patent implements a universal elevator management server that serves multiple buildings and elevator systems through a standardized protocol. Instead of developing separate protocols for each building, the system uses a single unified server that can manage elevators across different buildings, achieving versatility without proportional increases in complexity. The server handles authentication, control requests, and coordination for multiple elevators through one centralized interface.
Solution Approach 2:
The elevator management server acts as an intermediary between robots and elevator systems. Rather than robots directly controlling elevators (which would require complex building-specific protocols), the server mediates all control requests, authentication, and coordination. This intermediary layer simplifies the robot's interface while providing comprehensive elevator management capabilities.
2Speed
If a robot controls elevators directly, then control responsiveness is improved, but development efficiency and standardization deteriorate
Solution Approach 1:
The system performs preliminary authentication and authorization actions through the elevator management server before actual elevator control. The robot sends control requests to the server, which pre-validates permissions, authentication keys, and control parameters. This preliminary processing enables responsive direct control while maintaining standardized development procedures through the server's pre-established protocols.
3Productivity
If standardized elevator control service is implemented, then program development efficiency is improved, but system authentication and security requirements increase
Solution Approach 1:
The elevator management server implements self-service authentication mechanisms where authentication keys are automatically generated, validated, and managed by the system itself. The server handles authentication requests from robots and elevators automatically, maintaining security protocols while reducing manual intervention. This automation enhances both security reliability and development efficiency by providing standardized authentication procedures.
Data Source
AI summary
An elevator management device includes a database, a processor, and a communication unit. The database is configured to store a first identification number corresponding to a first layer representing a group of multiple buildings, a second identification number corresponding to a second layer representing one of the multiple buildings, a third identification number corresponding to a third layer representing multiple elevators in the one building, and a fourth identification number corresponding to a fourth layer representing one of the multiple elevators, the elevator management device receives an authentication key and an elevator control request via the communication unit, and the processor is configured to verify whether the received authentication key is an authentication key generated by the elevator management device and transmit the request to an elevator control terminal when a verification is made that the received authentication key is an authentication key generated by the elevator management device.
