Access Control Module with ID Transmitter Data Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems face challenges with wireless data exchange, including long response times and potential malfunctions due to radio link interruptions, and require frequent reprogramming and data synchronization when ID transmitters are lost or access rules change.
Innovation Solution
Storing access control data on the ID transmitter instead of the control center or access control module, allowing the first access control module to make independent decisions based on read data, and enabling data exchange only on request, simplifying the system's structure and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If access control data is stored on the ID transmitter instead of the control center, then the response time is reduced and the system complexity is reduced, but the security risk increases if the ID transmitter is lost
Solution Approach 1:
The system performs preliminary actions by storing access control data on the ID transmitter in advance, enabling the access control module to make independent decisions without real-time communication with the control center. This preliminary data storage on the transmitter allows immediate access decisions, reducing response time while maintaining security through pre-configured access rules and validity periods.
2Loss of information
If the wireless access control module is permanently connected to the control center via radio link, then data exchange is enabled, but the response time increases and the system becomes vulnerable to radio interruptions
Solution Approach 1:
The invention extracts the access control data from the control center and places it directly on the ID transmitter. This extraction allows the access control module to read necessary data locally from the transmitter without requiring continuous wireless communication with the control center, thereby reducing response time and eliminating vulnerability to radio link interruptions while maintaining data exchange capability for system management.
3Reliability
If the access control modules are reprogrammed frequently to maintain security, then the security is maintained, but the operational burden increases
Solution Approach 1:
The system implements periodic action through time-based access control rules stored on the ID transmitter, which automatically expire after specified validity periods. This periodic validity mechanism maintains security by ensuring access rights are time-limited, while reducing operational burden because the system automatically manages expiration without requiring frequent manual reprogramming or comparison operations with the control center.
