UAV Flight Control Using Shared External Flight Indication Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned aerial vehicles (UAVs) face increased costs, volume, and reduced flight time due to the need for various sensors for flight control, which can be mitigated by implementing a flight control method that relies on shared flight indication data from other UAVs or servers.
Innovation Solution
A flight control method for UAVs that receives and processes flight indication data from external sources, including three-dimensional environmental maps, obstacle data, and no-fly zone information, to generate control instructions without the need for onboard sensors, thereby reducing the necessity for carrying multiple detecting devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If various sensors are mounted on the aerial vehicle to acquire flight indication data, then the flight control capability is improved, but the cost, volume, and weight of the aerial vehicle increase significantly
Solution Approach 1:
The patent introduces a server as an intermediary that stores and provides flight indication data to multiple aerial vehicles. Instead of each aerial vehicle carrying its own sensors to detect environmental data, the server acts as a central repository that receives, processes, and distributes flight indication data including three-dimensional environmental maps, obstacle information, and no-fly zone data to aerial vehicles that only need basic communication capabilities.
Solution Approach 2:
The patent implements a data copying mechanism where flight indication data is detected once by a source aerial vehicle or server, then copied and distributed to multiple other aerial vehicles via the communication module. This allows multiple aerial vehicles to access the same environmental information without each needing to carry identical sensor equipment, significantly reducing the number of sensors required on each individual vehicle.
2Reliability
If various sensors are mounted on the aerial vehicle to acquire flight indication data, then the flight control capability is improved, but the weight of the aerial vehicle increases
Solution Approach 1:
The server serves as an intermediary that centralizes the storage and distribution of flight indication data, eliminating the need for each aerial vehicle to carry heavy sensor equipment. The aerial vehicle only needs to weight the communication module and basic processing unit, while the server handles the complex sensor data storage and distribution.
Solution Approach 2:
By copying flight indication data from a central source to multiple aerial vehicles through wireless communication, the patent eliminates the need for each vehicle to carry its own complete set of sensors. This data copying approach dramatically reduces the weight of each individual aerial vehicle while maintaining flight control capability.
3Reliability
If various sensors are mounted on the aerial vehicle to acquire flight indication data, then the flight control capability is improved, but the volume of the aerial vehicle increases
Solution Approach 1:
The server acts as a centralized intermediary that stores large volumes of flight indication data including three-dimensional environmental maps and obstacle information. Aerial vehicles only need minimal onboard processing and communication equipment, dramatically reducing their volume compared to vehicles that would need to carry complete sensor suites and data storage systems.
Solution Approach 2:
The patent uses data copying to transfer flight indication data from the server to aerial vehicles via wireless communication. This eliminates the need for aerial vehicles to carry large onboard storage systems and sensor arrays, reducing their volume to only what is necessary for communication and basic processing.
4Reliability
If various sensors are mounted on the aerial vehicle to acquire flight indication data, then the flight control capability is improved, but the remaining flight time of the aerial vehicle is shortened
Solution Approach 1:
The server as an intermediary centralizes the computational burden of processing and analyzing flight indication data. Aerial vehicles only need to receive and execute commands based on data provided by the server, significantly reducing their onboard energy consumption and extending flight time compared to vehicles that would need to perform complex real-time sensor data processing.
Solution Approach 2:
By copying pre-processed flight indication data from the server to the aerial vehicle, the patent eliminates the need for the aerial vehicle to perform energy-intensive real-time sensor data acquisition and processing. The aerial vehicle only consumes energy for receiving and executing flight control instructions, dramatically extending its remaining flight time.
