Radar Installation Angle Adjustment Assistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of infrastructure radars for traffic monitoring is challenging due to the lack of power supply and knowledge about angle adjustments during initial setup, leading to varied and suboptimal angles, requiring frequent dismounting and reinstallation for accurate adjustment.
Innovation Solution
A radar installation angle adjustment assistance apparatus and computer program that displays an assistance screen showing target and detected angles, with a determination result indicating whether the angle difference is within a predetermined range, allowing users to adjust the radar angles accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If infrastructure radar is installed during initial setup without power supply and angle adjustment knowledge, then installation can be completed quickly, but the radar angles become varied and suboptimal, requiring frequent dismounting and reinstallation
Solution Approach 1:
The system enables self-service adjustment by providing a user interface that displays target angles and detected angles, allowing operators to adjust radar angles independently without requiring expert knowledge or repeated dismounting/reinstallation cycles
Solution Approach 2:
The system implements feedback by continuously monitoring the detected angle via angle sensor and comparing it with the target angle, then displaying the angle difference to guide operators in making precise adjustments to achieve optimal radar alignment
2Manufacturing precision
If expert knowledge is required for angle adjustment, then accurate radar alignment can be achieved, but the adjustment process becomes complex and requires frequent reinstallation
Solution Approach 1:
The control unit acts as an intermediary that translates complex angle measurement and comparison operations into simple visual guidance on the user interface, mediating between the sophisticated angle sensing system and the operator to simplify the adjustment process while maintaining precision
3Manufacturing precision
If frequent dismounting and reinstallation is performed for accurate adjustment, then radar angle precision can be improved, but time consumption and operational complexity increase
Solution Approach 1:
The system performs preliminary action by calculating and displaying the target angle before adjustment begins, and continuously showing the angle difference during adjustment, enabling operators to achieve precise alignment in a single adjustment session without repeated dismounting and reinstallation

AI summary
A radar installation angle adjustment assistance apparatus includes: a display device; and a display control unit configured to cause the display device to display an assistance screen for assisting adjustment of an installation angle of an infrastructure radar. The assistance screen includes a target value display part configured to display a target value of the installation angle of the infrastructure radar, a detection angle display part configured to display the installation angle of the infrastructure radar detected by an angle sensor, and a determination result display part configured to display a determination result of determination as to whether or not an angle difference between the target value and the installation angle is included in a predetermined set range. When the angle difference is not included in the predetermined set range, the display control unit causes an angle based on the angle difference to be displayed on the assistance screen.
