Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surveillance systems on aircraft are inefficient in resource utilization and prone to unauthorized access due to unattended mobile transport containers and other objects, necessitating improved data processing and monitoring solutions.
Innovation Solution
A dynamically adjustable surveillance system with external triggers from sensing devices, such as latch sensors, controls operation parameters of surveillance cameras, including resolution, frame rate, and storage, to enhance monitoring efficiency and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video surveillance continuously monitors mobile transport containers at high resolution and frame rate, then monitoring precision and reliability are improved, but data processing resources and storage capacity are excessively consumed
Solution Approach 1:
The surveillance system dynamically adjusts its monitoring parameters based on the operational state of the mobile transport container. When the container is in a secure state (latch engaged), the system reduces monitoring intensity. When the latch state changes or unauthorized access is detected, the system automatically increases resolution and frame rate to capture detailed evidence, thus optimizing resource usage while maintaining reliability when needed
Solution Approach 2:
The system changes operational parameters (resolution, frame rate, storage duration) based on detected events and latch states. Normal operation uses lower parameters to conserve resources, while suspicious activities or security events trigger parameter increases to ensure high-quality monitoring and evidence capture
2Loss of information
If the surveillance system stores all captured video image data permanently, then data completeness for security analysis is improved, but storage resource consumption increases significantly
Solution Approach 1:
The system applies different storage quality and duration policies to different video segments based on their importance. Video data captured during secure periods is stored with lower priority or shorter retention, while data captured during events (latch changes, unauthorized access attempts, suspicious activities) is stored permanently with high priority, ensuring critical information is preserved without filling storage capacity
3Measurement precision
If the surveillance system operates in high-definition mode continuously, then image quality for incident analysis is improved, but energy consumption and data processing load increase
Solution Approach 1:
The system switches between different monitoring modes periodically or event-driven. During normal secure periods, it operates in low-power mode with reduced image quality. Upon detecting events such as latch state changes or suspicious activities, it transitions to high-definition periodic capture mode to ensure detailed documentation of the incident while minimizing overall energy consumption

AI summary
A dynamically adjustable surveillance system includes at least one surveillance camera having a field of vision encompassing an object to be monitored and generating an image stream of the field of vision, a surveillance camera controller configured to control operation parameters of the at least one surveillance camera, the operation parameters indicating operation conditions of the at least one surveillance camera, a surveillance controller coupled to the surveillance camera controller, and at least one sensing device coupled to the surveillance controller and configured to output an object state signal to the surveillance controller indicating a sensed state of the object to be monitored. The surveillance controller is configured to output a control signal to the surveillance camera controller to change some of the operation parameters of the at least one surveillance camera if the object state signal received from the at least one sensing device indicates a sensed state of the object to have changed.
