UAV Flight Prompting for Sensitive Area Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned aerial vehicles (UAVs) face challenges in navigating around sensitive areas due to the lack of effective information systems that provide real-time alerts and restrictions, potentially leading to liability issues for operators.
Innovation Solution
A system and method that utilize a UAV control terminal, processor, and memory to obtain sensitive area information, mark these areas on a navigation map, and generate prompt information based on the UAV's positional relationship with the sensitive areas, providing warnings, restrictions, or prohibitions through visual and audio cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UAV operators fly without real-time sensitive area information, then flight freedom is maintained, but liability risks increase due to potential violations of public security restrictions
Solution Approach 1:
The system pre-obtains and stores sensitive area information including coordinates, types, and restriction levels before flight operations begin. This preliminary preparation allows operators to access ready-made navigation data without real-time delays, ensuring both flight safety through advance awareness of restricted zones and operational freedom by providing pre-processed information that requires minimal intervention during flight
Solution Approach 2:
The patent introduces a remote server as an intermediary between UAV operators and sensitive area databases. The server pre-processes sensitive area information, performs coordinate transformations, and delivers processed data to operators. This intermediary role reduces the information processing burden on operators while ensuring accurate and reliable delivery of safety-critical data, balancing reliability and ease of operation
2Reliability
If comprehensive sensitive area information is provided to UAV operators, then flight safety is improved, but information processing complexity increases
Solution Approach 1:
The system extracts only the essential and relevant sensitive area information needed for safe flight operations, such as restricted zone coordinates, area types, and restriction levels. By selectively extracting this critical data from comprehensive databases and excluding unnecessary information, the system maintains high flight safety while significantly reducing the complexity of information processing and display for operators
Solution Approach 2:
The patent applies different levels of information detail to different operational contexts. The system provides comprehensive information when needed for safety-critical decisions while simplifying display and processing for routine operations. This localized adaptation of information quality ensures safety without overwhelming operators with unnecessary complexity in all situations
3Measurement precision
If real-time sensitive area data is obtained and processed, then prompt information accuracy is improved, but system response time increases
Solution Approach 1:
The system performs preliminary processing of sensitive area data including coordinate transformations, area calculations, and restriction level assignments before flight operations begin. This pre-computation ensures that when real-time position data arrives during flight, the system can quickly compare against pre-processed reference data and generate accurate prompt information without time-consuming calculations, thus maintaining both precision and speed

AI summary
A method of providing prompt information includes obtaining sensitive area information and marking a sensitive area on a navigation map according to the sensitive area information. The sensitive area affects a flight of an unmanned aerial vehicle (UAV). The method further includes obtaining position information of the UAV, determining a positional relationship between the UAV and the sensitive area according to the sensitive area information and the position information of the UAV, and generating the prompt information according to the positional relationship.
