Pan-Tilt Camera Wake-Up Tracking for Low-Power Security Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring equipment faces a challenge in balancing power consumption and security levels, as continuous active imaging mode consumes high power while low power consumption modes may fail to guarantee security due to missed detections.
Innovation Solution
A monitoring equipment system with an imaging device in two modes, a pan-tilt device, and a motion detection device that switches to active imaging mode upon detecting a moving object, adjusting the imaging orientation before fully powering up, thereby reducing power consumption while maintaining security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the imaging device operates in active mode all the time, then the security level is guaranteed, but the power consumption is too high
Solution Approach 1:
The motion detection device performs preliminary detection before the imaging device activates. When motion is detected, it triggers the imaging device to switch to active mode, ensuring that imaging only occurs when necessary for security monitoring, thus reducing overall power consumption while maintaining security coverage.
Solution Approach 2:
The system alternates between low-power standby mode and active imaging mode based on motion detection events. The imaging device remains in a low-power state during periods without motion and activates periodically when motion is detected, creating a rhythmic on-off pattern that balances security monitoring with power conservation.
2Use of energy by moving object
If the imaging device switches from first mode to second mode upon detecting motion, then power consumption is reduced, but there is a delay in capturing images of the moving object
Solution Approach 1:
The pan-tilt device performs preliminary orientation adjustment based on the initial position information from the motion detection device before the imaging device fully activates. This pre-positioning ensures that when the imaging device switches to active mode, it is already oriented toward the moving object, eliminating capture delay while maintaining power savings.
Solution Approach 2:
The system replaces the traditional sequential activation process with a parallel execution model where the pan-tilt mechanical adjustment and imaging device mode switching occur simultaneously. The pan-tilt device is triggered by motion detection to adjust orientation in parallel with the imaging device's mode transition, substituting the time-consuming sequential approach with a coordinated parallel process.
3Reliability
If the pan-tilt device adjusts imaging orientation after the imaging device activates, then the imaging device can capture images, but the moving object may have already moved out of the imaging range
Solution Approach 1:
The pan-tilt device receives initial position information from the motion detection device and begins adjusting the imaging orientation in advance, before the imaging device completes its mode switching. This preliminary orientation ensures that the imaging device is already positioned to capture the moving object when it becomes active, preventing the object from moving out of range.
Solution Approach 2:
The system implements a feedback loop where the motion detection device continuously provides position information to the pan-tilt device. Based on this feedback, the pan-tilt device dynamically adjusts the imaging orientation to track the moving object's position, ensuring the object remains within imaging range even as it moves.
