Building Access Control via Position-Based Terminal Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current access control systems in buildings face challenges such as cumbersome transfer of access rights, susceptibility to key loss, misuse, and high communication loads on long-range networks, which can lead to unauthorized access and complex administration, especially in large properties and historic buildings.
Innovation Solution
A system utilizing a remote server for access authorization storage, combined with a position determination and identification system for terminals, which communicates bidirectionally to verify user location and authorization without physical data carriers, minimizing long-range network communication and enhancing security by authenticating outside user influence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical data carriers (keys, cards) are used for access control, then ease of operation is improved, but reliability deteriorates due to key loss, misuse, and wear
Solution Approach 1:
The patent replaces mechanical data carriers (physical keys and cards) with a contactless identification system using electromagnetic fields. The identification device emits identification data wirelessly via an antenna, eliminating physical contact and the associated risks of loss, theft, and wear while maintaining ease of operation.
2Reliability
If electronic access control systems are installed in existing buildings, then reliability is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent describes a universal access control system that can be integrated into various building types and existing infrastructure. The control unit can manage multiple identification devices and structural elements, and the system adapts to different building configurations without requiring complete system replacements, thus reducing installation complexity.
Solution Approach 2:
The patent introduces a server as an intermediary component that centralizes access authorization management. The server stores authorization data and communicates with control units, simplifying the overall system architecture and reducing installation complexity by providing a centralized management point rather than distributed complexity.
3Ease of operation
If code locks with wireless PIN transfer are used, then ease of operation is improved, but reliability deteriorates due to PIN forgetting or unauthorized sharing
Solution Approach 1:
The patent uses identification data that can be copied or cloned on identification devices without physical contact. The identification data is emitted wirelessly and can be stored in multiple identification devices, enabling convenient access while maintaining security through centralized authorization management on the server that can revoke or control access rights.

AI summary
The invention relates to an arrangement and a method for the authorized access of at least one structural element located in a building. The arrangement comprises a remote server which is arranged in a long-range network and allocates and stores a personalized access authorization, in connection, via a first bidirectional communications channel, with a control unit located in the building and used to control said at least one structural element, a terminal which is allocated to a user, registered at the server and connected to said server via a second bidirectional communications channel, and a positioning and identification system for said terminal, which is located in the building and/or global and in communicative connection with the control unit and/or terminal.
