Radar Device Self-Localization for Coverage-Aware Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radar device deployment requires professional installation, leading to inefficiency and difficulty in achieving complete coverage without interference, especially in scenarios like whole-house intelligence where radar devices are often installed in hard-to-reach locations.
Innovation Solution
A communication method enabling ultra-wideband devices to self-localize and adjust their positions using a control device or primary device, allowing users to deploy radar devices efficiently by visualizing and optimizing radar coverage through spatial layout diagrams and prompt adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If radar devices are deployed by professional persons, then deployment accuracy and coverage optimization are improved, but deployment efficiency and ease of operation deteriorate
Solution Approach 1:
The radar device performs self-localization by autonomously determining its own location and calculating its coverage area using sensors and processors, eliminating the need for professional deployment personnel to manually measure and configure coverage parameters
Solution Approach 2:
The system provides real-time feedback by displaying the radar coverage area on a display component, allowing users to visually verify coverage and receive prompts for location adjustment, enabling iterative optimization without professional intervention
2Area of stationary object
If radar devices are installed in hard-to-reach locations, then coverage completeness is improved, but ease of operation and adjustability deteriorate
Solution Approach 1:
The radar device calculates and determines its coverage area immediately after deployment using self-localization algorithms, providing preliminary coverage assessment before user interaction is needed
Solution Approach 2:
The display component provides visual feedback about coverage completeness, and the processor generates prompt information guiding users on how to adjust the radar location to eliminate blind spots, making adjustment intuitive even for hard-to-reach installations
3Area of stationary object
If multiple radar devices are deployed to achieve complete coverage, then coverage completeness is improved, but device complexity and interference management worsen
Solution Approach 1:
The system merges coverage information from multiple radar devices by having each device calculate its own coverage area and the system collectively analyze overlaps and blind spots to optimize overall coverage
Solution Approach 2:
The system provides integrated feedback about the combined coverage state of all radar devices, identifying blind spots and prompting users to adjust specific devices to eliminate gaps, simplifying multi-device coordination

AI summary
A communication method, including obtaining a first initial location of a first device, a field of view of the first device, location information of a second device, and a field of view of the second device, displaying first radar coverage of the first device in a spatial layout diagram of the target area based on the first initial location of the first device and the field of view of the first device, displaying second radar coverage of the second device in the spatial layout diagram based on the location information of the second device and the field of view of the second device, and outputting first prompt information in response to detecting, based on the first radar coverage and the second radar coverage, a need to adjust at least one of a location of the first device or a location of the second device.
