Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wildfire detection systems are inefficient and slow due to limitations in lightning strike detection, particularly in accurately measuring long-continuing-current and charge transfer, which are key factors in fire ignition risk. Additionally, existing systems struggle with precise location accuracy and often rely on satellite data that is affected by cloud scattering, leading to inaccurate detection of High-Risk-Lightning strikes.
Innovation Solution
A novel system and method for detecting High-Risk-Lightning strikes using a network of detectors, environmental satellite data, and AI algorithms for signal processing. This system enables real-time detection of High-Risk-Lightning strikes, providing actionable intelligence for early wildfire detection and alerting first responders. The system includes a dual-band design for precise current duration and charge transfer measurements, and 3D lightning imaging capabilities for enhanced location accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If standard lightning locating systems are used to map lightning in two dimensions, then the system complexity is reduced, but the location precision and charge transfer measurement capability deteriorate
Solution Approach 1:
The patent transitions from two-dimensional lightning mapping to three-dimensional lightning mapping by incorporating vertical dimension measurements. This enables more precise location determination of lightning strikes and improves the ability to measure charge transfer, directly resolving the contradiction between system complexity and measurement precision.
2Area of stationary object
If satellite-based detection is used to determine lightning current duration, then the detection coverage is improved, but the measurement accuracy deteriorates due to cloud scattering
Solution Approach 1:
The patent introduces ground-based detectors as intermediary devices to measure lightning current duration and charge transfer directly at the strike location. These detectors serve as mediators between the lightning event and the satellite system, providing accurate local measurements that compensate for satellite limitations caused by cloud scattering, while maintaining broad detection coverage through satellite coordination.
3Reliability
If each lightning strike point is investigated to identify fire ignition locations, then the detection reliability is improved, but the time consumption and cost increase significantly
Solution Approach 1:
The patent applies local quality by focusing investigative resources only on high-risk lightning strike locations identified through the 3D mapping and charge transfer measurement system. Instead of uniformly investigating all lightning strikes, the system identifies and prioritizes locations with measured charge transfer above certain thresholds, thereby improving fire detection reliability while significantly reducing time and resource consumption.
4Area of stationary object
If fire camera systems with PTZ capabilities are deployed on large scale, then the detection coverage is improved, but the operational efficiency deteriorates due to underutilization of zoom capabilities
Solution Approach 1:
The patent implements preliminary action by using 3D lightning mapping and charge transfer measurements to pre-identify high-risk strike locations before fire investigation begins. This allows fire camera systems to be pre-positioned and zoomed in on specific high-risk areas in advance, rather than scanning broad areas and only zooming in after fire detection. This approach maintains large-scale detection coverage while dramatically improving operational efficiency by eliminating unnecessary scanning and zooming operations.

AI summary
A system and method for detecting in real-time High-Risk-Lightning (HRL) strikes and sending out alerts to responsible personnel to allow for earlier responses to lightning caused fire ignitions, and powerline damages, to help maintain and/or reduce the chance of spread by the wildfire, and reduce the amount of powerline downtime. The system and method allow for HRL events and fire ignitions/powerline damage points to be detected preferably within seconds. The system and method can use a network of detectors, data from environmental satellites and/or other environmental data sources, powerline data, and novel AI/algorithms for signal processing to relatively quickly locate fire ignition spots and powerline damage points. Thus, the system and method provide for actionable wildfire intelligence and powerline damage potential in real-time and to relatively quickly and accurately send out alerts when an HRL event has been determined. Cameras and drones can be used to provide real-time visualization at the location of the HRL event to verify or monitor any fire ignition or smoldering at the area of the HRL event, and to check the potential damage that the HRL strike has caused to the powerline. In one embodiment, all of the main components for the detection system can be located together out in the field and preferably connected to a pole or other vertical or substantially vertically oriented object. The system can also include a concentric antenna configuration for the high frequency antenna and low frequency antenna.
