Mobile Access Unlock Timing for Reader Error Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access systems experience communication and software issues between mobile devices and reading devices, leading to delays or failures in unlocking, particularly in frequently used systems, causing unauthorized persons to be unable to enter restricted areas.
Innovation Solution
A method for unbolting an access system using a mobile device that involves receiving a communication signal, determining a time duration between signal transmission and decision-making, and performing error detection by comparing this duration with threshold values to identify and rectify software or hardware issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication technologies are used to communicate between mobile device and reading device, then ease of operation is improved, but reliability deteriorates due to communication errors and software problems
Solution Approach 1:
The system measures the time duration between receiving the unbolting signal and making the unbolting decision, then compares this measured value with threshold values to detect errors. This feedback mechanism monitors the unbolting process and identifies communication or software problems by detecting abnormal time delays.
Solution Approach 2:
The system establishes threshold values in advance that define normal operation ranges. These pre-set thresholds enable the system to quickly identify deviations from normal behavior without requiring complex real-time analysis, allowing for rapid error detection.
2Reliability
If error detection and threshold comparison processes are implemented, then reliability is improved through error detection, but device complexity increases
Solution Approach 1:
The reading device autonomously performs error detection by measuring time durations and comparing them with pre-stored threshold values. The system self-monitors its own operation and automatically identifies errors without requiring external monitoring equipment or complex diagnostic systems.
3Productivity
If time duration measurement and error detection are performed, then productivity is improved by preventing access failures, but loss of time increases due to additional measurement and comparison steps
Solution Approach 1:
The system changes the parameter being monitored from simple signal presence to time duration measurement. By measuring how long the unbolting process takes and comparing it against threshold values, the system can detect errors without adding significant time to the normal operation, as the measurement occurs during the existing operational timeline.

AI summary
A method for unbolting an access system using a mobile device and/or for error detection is provided, relating to an unbolting of an access system,with the access system having a reading device with a communication interface for receiving communication signals from the mobile device, with the method including the following steps:a) Receiving a first communication signal, relating to an unbolting of the access system by way of the reading device from the mobile device at a first point in time,b) making an unbolting decision for the access system—at a second point in time after the first point in time—by way of the reading device,wherein a first time duration is determined and/or measured as a function of the first point in time and the second point in time, andc) performing an error detection as a function of the first time duration.
