Access Control Device Pairing via Group Identifier Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems require cumbersome configuration of devices that rely on fully online connectivity, making the process inconvenient and prone to errors.
Innovation Solution
A method for configuring devices in an access control system using group identifiers, allowing devices to associate and communicate locally without requiring full online connectivity, through a configuration device that transfers group identifiers to end devices and communication hubs, enabling them to discover and match, thus establishing communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If configuration is performed using traditional online connectivity methods, then communication between devices can be established, but the configuration process becomes cumbersome and requires full online connectivity
Solution Approach 1:
The patent applies preliminary action by pre-configuring group identifiers in the configuration device before approaching the end device. This allows the configuration data to be ready and transferred via short-range wireless communication without requiring online connectivity during the actual configuration moment, thus making the process easier while ensuring reliable communication establishment.
2Ease of operation
If devices are configured to communicate over local wireless interface, then configuration convenience is improved, but online connectivity is lost during configuration
Solution Approach 1:
The configuration device pre-loads the group identifier from a server online before the configuration process. This preliminary online action separates the online data retrieval phase from the offline configuration execution phase, allowing convenient local configuration without real-time online connectivity while ensuring the device has the necessary configuration data.
Solution Approach 2:
The configuration device acts as an intermediary that bridges the online server and the end device. It retrieves configuration data online from the server, stores it locally, and then transfers it to the end device via short-range wireless communication. This intermediary approach allows the end device to be configured offline while the server remains online, resolving the connectivity contradiction.
3Device complexity
If group identifiers are used for device association, then configuration complexity is reduced, but manual input requirements increase
Solution Approach 1:
The end device automatically receives and processes the group identifier through short-range wireless communication from the configuration device. The device autonomously configures itself using the received identifier without requiring manual user input, thus reducing both configuration complexity and manual input requirements simultaneously.

AI summary
It is provided a method for configuring communication between a first device (11) and a second device (12) of an access control system (9), the first device (11) being one of an end device (1) and a communication hub (2), and the second device (12) being the other of the end device (1) and the communication hub (2). The method comprises: obtaining (40) configuration data comprising a first group identifier; configuring (42) the first device (11) to be associated with the first group identifier; obtaining (44) a second group identifier by communicating with the second device (12), wherein the second group identifier is a group identifier for the second device (12); determining (46) that the first group identifier and the second group identifier match; and configuring (48) the first device (11) to perform future communication with the second device (12) over a local wireless communication interface.
