Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional commercial surveillance systems require significant investments in video cameras and are prone to missing conditions, leading to false alarms that waste resources and time, and autonomous mobile unmanned machines like drones and robots face challenges in securely accessing doors within facilities.
Innovation Solution
Implementing a method where autonomous mobile unmanned machines receive beacon signals to determine access needs, send requests to an access control system, and receive authentication to unlock doors, using sensors and credentials to manage access and reduce false alarms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional video surveillance systems are deployed to cover all critical areas, then surveillance coverage is improved, but system cost and complexity increase significantly
Solution Approach 1:
The autonomous mobile unmanned machine performs surveillance tasks independently without requiring a complex network of video cameras. The single machine navigates through the facility, accesses doors autonomously using beacon signals and access control integration, and collects surveillance data itself, eliminating the need for extensive camera infrastructure and reducing system complexity while maintaining coverage reliability
Solution Approach 2:
The autonomous mobile unmanned machine serves multiple functions: it performs surveillance, navigates autonomously, communicates with access control systems, and integrates with beacon signaling. This multi-functional device replaces what would otherwise require separate systems for surveillance, door access control, and navigation, thereby reducing overall system complexity while maintaining comprehensive coverage
2Reliability
If conventional video surveillance systems are deployed to cover all critical areas, then surveillance coverage is improved, but investment cost increases significantly
Solution Approach 1:
The autonomous mobile unmanned machine independently performs surveillance and navigation tasks, eliminating the need for expensive infrastructure such as multiple video cameras, DVRs, and video management tools. The machine uses its own onboard sensors and processors to collect and analyze data, significantly reducing the hardware investment required while maintaining comprehensive surveillance coverage
Solution Approach 2:
The autonomous mobile unmanned machine represents a more cost-effective alternative to deploying expensive video camera infrastructure throughout the facility. By using a single or few autonomous units instead of numerous fixed cameras, the system reduces capital expenditure on hardware while maintaining effective surveillance coverage
3Ease of operation
If autonomous mobile unmanned machines are allowed to access doors freely, then ease of operation is improved, but security risk increases
Solution Approach 1:
The access control system acts as an intermediary between the autonomous mobile unmanned machine and the door locking mechanism. The machine communicates its identity and access requests to the access control system, which verifies credentials and controls door unlocking. This intermediary layer enables easy autonomous access while maintaining security through centralized authentication and authorization
Solution Approach 2:
The system implements feedback loops where the autonomous mobile unmanned machine receives status information from the access control system regarding door lock state and access authorization. The access control system continuously monitors and responds to access requests, providing real-time feedback on security status. This feedback mechanism ensures secure access control while enabling smooth autonomous operation

AI summary
Techniques for an autonomous mobile unmanned machine such as an unmanned aerial vehicle or drone or a robot to access a closed door are described. The techniques include programming the autonomous mobile unmanned machine to pass through a particular location within a facility that has one or more doors, and sense by the autonomous mobile unmanned machines a beacon signal emanating from a beacon deployed in proximity to a first one of the one or more doors in the facility, by receiving the beacon signal by a receiver device on the autonomous mobile unmanned machines. The techniques send a message to either a server or an access control system when the autonomous mobile unmanned machines determines that it needs access through the door at the specified location identified by the beacon and receives a message from either the server or the access control system that the door has been unlocked.
