Ultra-Wideband Access Control Device Location Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems require significant installation effort and cost due to the need for access control devices to be installed in close proximity to each barrier, making them inflexible and costly to extend or reconfigure, especially when multiple barriers are involved.
Innovation Solution
An access control device utilizing ultra-wideband transceivers to determine the physical location of authentication devices within a secure area through signal properties, allowing for precise location determination and reduced installation requirements, as it does not need to be installed directly next to each barrier, and can control multiple barriers with shared access control devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access control devices are installed in close proximity to each barrier, then reliable access control for each barrier is ensured, but installation effort and cost increase significantly
Solution Approach 1:
The system divides the secure area into multiple security perimeters, each associated with specific barriers. The access control device processes authentication requests by determining which perimeter the authentication device is located in, allowing one access control device to manage multiple barriers across different perimeters rather than requiring dedicated devices at each barrier location.
Solution Approach 2:
The patent introduces an intermediary mechanism using ultra-wideband signal properties to determine the physical location of authentication devices. This location determination acts as a mediator between the access control device and the barriers, enabling the access control device to identify which barrier(s) should be controlled based on the authentication device's location without requiring physical proximity to each barrier.
2Reliability
If access control devices are installed in close proximity to each barrier, then cross-talk between devices is avoided, but system flexibility for extension and reconfiguration is reduced
Solution Approach 1:
The system dynamically determines the association between authentication devices and barriers based on real-time location data. Instead of static physical proximity, the access control device uses ultra-wideband signal processing to identify which perimeter the authentication device is in, allowing the system to adapt to different barrier configurations and authentication device locations without physical reinstallation of access control devices.
Solution Approach 2:
A single access control device is designed to control multiple barriers across different security perimeters. The device universally handles authentication requests from any perimeter by determining the authentication device's location and routing the request to the appropriate barrier(s), eliminating the need for dedicated access control devices at each barrier location.
3Ease of manufacture
If access control devices are installed remotely from barriers, then installation effort is reduced, but precise control over access may be compromised
Solution Approach 1:
The patent replaces the mechanical approach of physical proximity-based access control with an electromagnetic field-based system. Ultra-wideband radio frequency signals are used to determine the physical location of authentication devices through signal property analysis, enabling precise location determination without requiring physical closeness between the access control device and barriers.
Solution Approach 2:
The system changes the critical parameter from physical distance to signal-based location coordinates. By using ultra-wideband signal properties (such as time of flight, signal strength, or phase information) to determine the authentication device's position, the system maintains precise control over access while allowing the access control device to be installed remotely from the barriers it controls.
