Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack effective methods for utilizing unmanned aerial vehicles (UAVs) or drones in emergency situations involving moving objects, particularly in determining the appropriate operation mode and communication protocols to efficiently transmit event-related information.
Innovation Solution
A method and apparatus for a moving object equipped with a UAV or drone that detects events, determines the operation mode (first or second mode) based on the event and location, and communicates with other devices using transceivers and processors to transmit messages via broadcast or unicast methods, enabling the drone to switch between sleep and awake states for flight operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drone operates continuously in awake state, then event detection and communication capability is improved, but energy consumption increases
Solution Approach 1:
The drone is pre-configured with event detection algorithms and communication protocols while in sleep state. When an event is detected by the moving object, the drone is quickly awakened with pre-loaded capabilities, reducing the time to respond while avoiding continuous operation
Solution Approach 2:
The drone operates in periodic cycles of sleep and awake states. It transitions to awake state only when events are detected, maintaining periodic monitoring capability while minimizing energy consumption during non-critical periods
2Area of stationary object
If the drone transmits event information via broadcast method, then communication coverage is improved, but network traffic and interference increase
Solution Approach 1:
The communication method is adapted locally based on event type and location. Critical events in dense areas use unicast to nearby specific receivers, while general events in sparse areas use broadcast, optimizing energy efficiency for each local context
Solution Approach 2:
The transmission method dynamically switches between broadcast and unicast based on real-time conditions including event severity, receiver density, and network status, allowing the system to adapt communication strategy to current requirements
3Adaptability or versatility
If the drone is equipped with multiple operation modes, then adaptability to different events is improved, but device complexity increases
Solution Approach 1:
The operation modes are segmented into distinct categories (first operation mode for local broadcast, second operation mode for remote unicast). Each mode handles specific event types, dividing the complex response space into manageable segments with clear decision boundaries
Solution Approach 2:
The drone's communication system is designed with universal protocols that can handle both broadcast and unicast transmissions using the same hardware infrastructure. The dual-mode operation provides multi-functionality without requiring separate dedicated systems for each mode

AI summary
A method of operating a moving object on which a drone is mounted includes detecting, by the moving object, occurrence of an event; determining whether to use the drone, on the basis of the detected event; and determining an operation mode, among a first operation mode and a second operation mode, of the drone when the drone is used.
