Digital Antenna Automatic Feedback Adjustment Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital antenna units require manual adjustment for optimal receiving direction and elevation, which is time-consuming and labor-intensive, and existing automatic adjustment systems are either inefficient or limited to specific applications, failing to provide quick and accurate adjustments due to environmental and satellite position changes.
Innovation Solution
An automatic feedback adjustment device comprising a trafficator, antenna direction driver unit, secondary controller, primary controller, tuner, and demodulator, which retrieves actual direction and elevation data from the digital antenna unit, processes signal quality information, and adjusts the antenna to the optimal receiving position using motor-driven mechanisms and network data for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment is used to position the digital antenna unit, then the receiving direction can be adjusted, but it consumes excessive time and labor and cannot respond to environmental changes
Solution Approach 1:
The system enables the digital antenna unit to automatically adjust its own position through feedback from the trafficator and control from the primary and secondary controllers, eliminating the need for manual operation and continuous human intervention to maintain optimal receiving direction
Solution Approach 2:
The trafficator retrieves feedback on the actual direction and elevation angle of the digital antenna unit, which is then processed by the secondary controller and primary controller to automatically adjust the antenna position, creating a closed-loop system that responds to environmental changes without manual intervention
2Ease of operation
If electric motor unit is attached to drive automatic adjustment, then manual labor is reduced, but the adjustment speed and accuracy are insufficient
Solution Approach 1:
The patent replaces simple mechanical motor-driven adjustment with an intelligent control system that uses the trafficator to retrieve actual direction feedback, processes data through secondary and primary controllers, and drives precise positioning, substituting crude mechanical automation with sophisticated electromechanical control
Solution Approach 2:
The control system is divided into multiple components: the trafficator for feedback retrieval, the secondary controller for initial processing, and the primary controller for final decision-making, allowing each segment to specialize in specific functions that collectively achieve high precision
3Extent of automation
If scanning method is used to search for optimal direction, then automatic adjustment is achieved, but the time consumption increases significantly
Solution Approach 1:
The system obtains optimal direction data in advance from network data or storage devices, eliminating the need for time-consuming scanning and search operations. The pre-acquired directional information is directly applied to position the antenna, significantly reducing adjustment time
4Device complexity
If fixed antenna position is used, then device complexity is reduced, but the system cannot adapt to environmental changes and satellite position variations
Solution Approach 1:
The patent transforms the fixed antenna system into a dynamic one where the trafficator continuously retrieves feedback on actual direction and elevation, and the control system automatically adjusts positions in response to environmental changes, satellite movements, and other varying conditions
