Spraying UAV Early-Warning Range Adjustment for Staff Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional unmanned aerial vehicles (UAVs) performing automatic spraying operations along preset paths cannot intelligently pause or adjust their spraying when unexpected staff appears in the operation area, leading to safety concerns.
Innovation Solution
An automatic spraying UAV system with a dynamic early-warning range adjustment capability, equipped with a UAV transmission module, flight control module, image analysis module, range calculation module, and spraying control module, which analyzes the forward direction and speed of staff in environment videos to calculate an extended warning range and pause or resume spraying operations accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the UAV performs automatic spraying operation along a preset path without dynamic adjustment, then the operation efficiency and productivity are improved, but the safety is worsened because the UAV cannot respond to unexpected staff appearing in the operation area
Solution Approach 1:
The patent implements dynamic adjustment of the early-warning range based on real-time detection of staff in the operation area. The range calculation module dynamically extends or reduces the early-warning range according to the distance and position of detected staff, allowing the system to adapt between automated efficient spraying and safe pausing when staff are present
Solution Approach 2:
The image analysis module continuously monitors the operation area for staff presence and provides feedback to the range calculation module. This feedback loop enables the system to detect staff, calculate appropriate early-warning ranges, and adjust spraying operations in real-time, resolving the contradiction between automated efficiency and safety responsiveness
2Reliability
If the UAV extends the early-warning range to detect staff, then the safety is improved, but the operation time is worsened due to pausing spraying operations
Solution Approach 1:
The system extends the early-warning range beyond the actual spraying range only when staff are detected in the operation area. This partial extension approach ensures comprehensive safety coverage when needed while avoiding unnecessary pausing of spraying operations when the area is clear, thus minimizing time loss
Solution Approach 2:
The system dynamically changes the early-warning range parameter based on detected staff conditions. When staff are present, the range is extended to ensure safety; when no staff are present, the range returns to normal spraying operations, optimizing the balance between safety and operational time

AI summary
An automatic spraying unmanned aerial vehicle (UAV) system based on dynamic adjustment of early warning range and a method thereof are disclosed. In the automatic spraying UAV system, an unmanned aerial vehicle analyzes a forward direction and a forward speed of a staff appearing in an environment video, calculates a preset distance, and generates an early-warning range by extending outwardly a spraying range by a preset distance; when determining the staff appears within the early-warning range in the environment video, the unmanned aerial vehicle pauses an automatic spraying operation, so as to achieve the technical effect of improving safety of the staff in an operation area by dynamically adjusting the early-warning range of the automatic spraying operation of the unmanned aerial vehicle.
