Engineering Contradiction Analysis
1Area of stationary object
If traditional remote sensing systems deploy multiple cameras with integrated motion detection and illumination, then coverage area is improved, but system cost and complexity increase
Solution Approach 1:
The system divides the surveillance function into separate components: motion detection nodes with PIR sensors, camera nodes for imaging, and illumination nodes with LEDs. Each node performs a specific function and communicates wirelessly with others, allowing the system to cover larger areas without increasing individual node complexity.
Solution Approach 2:
The smartphone serves as a universal control platform that can function as a camera, process images, control illumination nodes, and coordinate motion detection. This multi-functional approach reduces the need for dedicated hardware for each function, simplifying the overall system architecture.
2Reliability
If traditional remote sensing systems use integrated camera and illumination nodes, then imaging capability is improved, but power consumption increases
Solution Approach 1:
The illumination nodes operate periodically rather than continuously, activating only when motion is detected by PIR sensors or when the camera requires illumination for imaging. This on-demand operation dramatically reduces power consumption while maintaining imaging capability when needed.
Solution Approach 2:
The system uses passive infrared sensors to automatically detect motion and trigger illumination or camera activation without requiring continuous power to active imaging components. The motion detection nodes independently monitor the environment and autonomously activate other nodes only when necessary.
3Area of stationary object
If traditional remote sensing systems deploy numerous cameras for large area coverage, then coverage area is improved, but deployment cost increases
Solution Approach 1:
Instead of deploying multiple complete surveillance units, the system segments functionality across multiple simple nodes. Each node contains only specific components (PIR sensor, camera, or illumination elements) and communicates wirelessly, reducing the cost per node and overall deployment expense while maintaining large area coverage.
Solution Approach 2:
Wireless communication acts as an intermediary between nodes, eliminating the need for expensive wired infrastructure and complex synchronization hardware. The smartphone serves as a central coordinator that manages communication between motion detection, camera, and illumination nodes, reducing system complexity and deployment cost.
Data Source
AI summary
A remote illumination and detection method, node, and system is described. The remote illumination and detection method generates a detection message when motion is detected by a detector. The detector includes a wireless communications module that wirelessly transmits the detection message to a remote sensing device. The remote sensing device includes a camera having a field of view and wirelessly communicates with the detector. The remote sensing device then proceeds to generate an illumination instruction to illuminate an area within the field of view, when the remote sensing device receives the detection message. The remote sensing device transmits the illumination instruction to an illuminator. The illuminator wirelessly communicates with the remote sensing device. The method then illuminates an area near the illuminator, when motion is detected by the detector and the illumination instruction is received by the illuminator.
