Intercom System Authority Transfer via QR Code Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intercom systems in communities and multi-story buildings lack efficient management and visitor identification processes, leading to inefficiencies in property management.
Innovation Solution
An integrated intercom system comprising an access control device, intercom indoor device, intercom management server, and mobile terminals that communicate via local and wireless networks, allowing for role-based management and two-dimensional code scanning for authority transfer, enabling secure and efficient visitor access control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional intercom systems are used in communities and multi-story buildings, then basic communication function is provided, but management efficiency is low and visitor identification process is inefficient
Solution Approach 1:
The intercom system is segmented into multiple functional modules including access control devices at different locations (entrance, floor, door), intercom management server, and mobile terminals. Each module performs specific functions and can be independently configured, enabling efficient management while maintaining system functionality.
Solution Approach 2:
The intercom system integrates multiple functions including visitor identification, access control, intercom communication, and management authority transfer into a single unified system. The access control devices and mobile terminals can perform multiple operations (scanning codes, receiving requests, granting access) reducing the need for separate dedicated devices for each function.
2Loss of time
If manual visitor identification and access control processes are used, then basic security is maintained, but time consumption and management burden increase
Solution Approach 1:
The manual mechanical process of visitor identification and access control is replaced with an automated electronic system. Access control devices automatically scan two-dimensional codes from visitor mobile terminals, verify permissions through the management server, and control door locks electronically, eliminating manual verification steps and reducing time consumption.
Solution Approach 2:
Visitors can independently complete the identification and access control process by presenting their mobile terminal with a two-dimensional code. The system automatically processes the verification and grants access without requiring manual intervention from property management personnel, enabling self-service functionality.
3Reliability
If centralized management control is implemented, then security and access control are improved, but management complexity and operational difficulty increase
Solution Approach 1:
The intercom management server acts as an intermediary between access control devices and mobile terminals. It receives scanning results from access control devices, verifies permissions against stored data, and sends control commands back to devices. This centralized mediation ensures secure access control while simplifying device operations through automated processing.
Solution Approach 2:
The system implements feedback mechanisms where the management server continuously monitors access control operations, verifies code scanning results, and provides real-time responses. The access control devices receive feedback from the server regarding permission verification status and execute corresponding actions, ensuring reliable security control with automated operational simplicity.

AI summary
A method for managing an intercom system includes obtaining a householder management authority of an intercom official account by an intercom indoor device and transferring the householder management authority to a first mobile terminal of a householder. An intercom request can be generated by an access control device through which a visitor or other is seeking entry, the intercom request being received by the first mobile terminal of the householder. A communication with the access control device can be established, and the access control device can be controlled to open or not open a door. An intercom system is also provided.
