Pan-Tilt Monitoring Camera Wake-Up for Low-Power Motion Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring equipment faces a challenge in balancing power consumption and security level, as continuous operation for security often consumes high power, while reducing power consumption compromises security effectiveness.
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 a low-power mode until an object is detected, then rapidly adjusts the imaging orientation using the pan-tilt device to capture images, reducing power consumption while ensuring security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the monitoring equipment operates continuously in active mode to capture images, then the security level is guaranteed, but the power consumption becomes too high
Solution Approach 1:
The motion detection device performs preliminary detection in low-power mode before the imaging device activates. When motion is detected, it triggers the imaging device to switch to active mode and the pan-tilt device to pre-position toward the detected direction, ensuring the imaging device is ready to capture images immediately without security delay while having operated in low-power mode until necessary
Solution Approach 2:
The system dynamically switches between different operational modes based on real-time conditions. The imaging device alternates between low-power mode (not capturing images) and active mode (capturing images), while the pan-tilt device adjusts its activation state dynamically. This dynamic operation allows the system to adapt to varying security requirements and environmental conditions, optimizing the balance between power consumption and security level
2Use of energy by moving object
If the monitoring equipment reduces power consumption by not capturing images continuously, then power consumption decreases, but the security level may not be guaranteed
Solution Approach 1:
The motion detection device continuously monitors the environment and provides feedback signals to control the imaging device's operational state. When motion is detected, the feedback triggers the imaging device to switch from low-power mode to active mode immediately. This feedback mechanism ensures that the system maintains high security level by responding promptly to potential threats while minimizing power consumption during normal conditions
Solution Approach 2:
The motion detection device performs preliminary monitoring in low-power mode and prepares to trigger the imaging device before actual image capture is needed. This preliminary detection capability allows the system to maintain security by being ready to capture images immediately when motion is detected, rather than waiting for the imaging device to wake up from sleep mode
3Use of energy by moving object
If the imaging device switches from low-power mode to active mode quickly, then power consumption is reduced, but there may be delay in capturing images of moving objects
Solution Approach 1:
When the motion detection device detects motion, it simultaneously triggers two preliminary actions: (1) activates the imaging device to switch from low-power mode to active mode, and (2) controls the pan-tilt device to pre-position toward the detected direction. This dual preliminary action ensures that both the imaging device and pan-tilt device are ready to capture images immediately without sequential delays
Solution Approach 2:
The control device acts as an intermediary that coordinates between the motion detection device, imaging device, and pan-tilt device. It receives detection signals and simultaneously initiates the switching of the imaging device and the adjustment of the pan-tilt device, eliminating sequential processing delays and enabling parallel execution of critical functions
