Drone Emergency Control Circuit Using 3D Danger Maps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drone communication systems are not suited for drones that fly in 3-dimensional spaces, as they are designed for 2-dimensional terminal devices, leading to safety concerns in emergency situations due to wind influences and lack of specific facilities like airports.
Innovation Solution
A circuit and base station system that reports and controls action-allowable time information and danger levels for drones, using a map to guide emergency actions, allowing drones to autonomously navigate and land safely by referencing a crash map with defined danger levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing 2-dimensional terminal device communication systems are used for drones, then system compatibility is maintained, but safety in emergency situations deteriorates due to lack of 3-dimensional space considerations and wind influence handling
Solution Approach 1:
The patent transitions from 2-dimensional terminal device communication to 3-dimensional drone communication by introducing vertical position information and crash maps that account for three-dimensional space. The base station determines crash maps based on 3D spatial coordinates and communicates them to terminal devices, enabling safety decisions in three-dimensional flight environments.
2Adaptability or versatility
If specific facilities like airports are required for emergency landing, then controlled emergency landing is possible, but adaptability to various emergency situations deteriorates when facilities are unavailable or weather conditions are unfavorable
Solution Approach 1:
The patent enables terminal devices to autonomously determine emergency landing positions using crash map information provided by the base station. The terminal device independently evaluates its situation against the crash map and selects appropriate landing positions without requiring external facility guidance, making the system self-sufficient in emergency situations.
Solution Approach 2:
The base station pre-determines and communicates crash maps to terminal devices before emergencies occur. These crash maps contain pre-calculated safe landing position information based on 3D spatial data, allowing terminal devices to quickly make safety decisions during emergencies without complex real-time calculations.
3Reliability
If action-allowable time information is reported to base station, then base station can make informed decisions, but communication time and system complexity increase
Solution Approach 1:
The patent implements a feedback mechanism where terminal devices report action-allowable time information to the base station, which then determines appropriate crash maps based on this feedback. This closed-loop communication allows the base station to make accurate safety decisions while minimizing communication overhead by only exchanging essential time-critical information.
