Electronic Access Terminal Remote Maintenance via Mobile Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stand-alone or off-line electronic terminal devices in access control systems, lacking direct communication links to back-end systems, face challenges in software upgrades and hardware maintenance due to their isolation from remote systems.
Innovation Solution
An electronic terminal device equipped with a radio communication module for bidirectional wireless data exchange with a mobile communication device, which generates and transmits a terminal report message containing operational parameters and authorization data, allowing the mobile device to forward this information to a back-end system via a telecommunications network, enabling remote monitoring and maintenance without a direct link.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic terminal devices are designed as stand-alone or off-line devices without direct communication links to back-end systems, then device independence and security are improved, but software upgrade capability and maintenance accessibility deteriorate
Solution Approach 1:
The patent introduces a mobile communication device as an intermediary between the stand-alone electronic terminal device and the back-end system. The mobile device establishes a temporary direct wireless communication link with the terminal device, enabling bidirectional data exchange for software updates and maintenance operations without requiring a permanent communication infrastructure at the terminal device location.
2Productivity
If electronic terminal devices include direct communication modules for constant connection to back-end systems, then software update frequency and maintenance responsiveness are improved, but device complexity and cost increase
Solution Approach 1:
The system enables self-service software updates by allowing the terminal device to autonomously receive and install software updates through temporary wireless connections with mobile devices. The terminal device initiates update requests, receives update packages, and performs installation without requiring complex built-in communication infrastructure or manual intervention, thereby achieving frequent updates with minimal device complexity.
3Ease of manufacture
If stand-alone electronic terminal devices operate without direct back-end system connections, then deployment flexibility and installation ease are improved, but remote monitoring capability and system manageability deteriorate
Solution Approach 1:
The system implements periodic remote monitoring by establishing scheduled temporary wireless connections between mobile devices and terminal devices. During these periodic connection intervals, operational data, status information, and diagnostic data are transmitted from the terminal device to the back-end system, enabling continuous remote monitoring capability while maintaining the terminal device's stand-alone operational nature and deployment flexibility.

AI summary
A method of communicating between a terminal device and a back-end system assigned to the terminal device, the terminal device receives via a direct wireless communication link an authorization code from the mobile communication device. Responsive to receiving the authorization code, the terminal device transmits via the direct wireless communication link to the mobile communication device a terminal report message which includes a message content part and a message addressing part. The mobile communication device transmits the terminal report message in a forwarding message via a telecommunications network to a remote message processing system determined by the addressing part. The remote message processing system determines from the addressing part the back-end system assigned to the electronic terminal device and transfers the content part of the terminal report message to the back-end system.
