Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lightning detection systems for structures susceptible to lightning strikes are technically complex and costly, requiring high sophistication to ensure accurate and reliable estimation of the structure's condition post-strike, but they often lack the necessary localization accuracy and are prone to electromagnetic interference.
Innovation Solution
A system that combines data from a wide-area lightning detector network with a local lightning detection system, using a processor to correlate spatially and temporally data to accurately determine if a structure was affected by a lightning strike, thereby simplifying the onboard detection equipment without compromising accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sophisticated local lightning detection system is installed onboard the structure, then the accuracy and reliability of condition estimation is improved, but the device complexity and cost increase
Solution Approach 1:
The patent introduces a wide-area lightning detection network as an intermediary system that provides lightning strike data to a central processing system. This central system acts as a mediator between the simple local detectors on structures and the complex analysis required for condition estimation, eliminating the need for each structure to have sophisticated onboard detection equipment while maintaining high accuracy through centralized processing of data from multiple sources.
2Reliability
If a sophisticated local lightning detection system is installed onboard the structure, then the accuracy and reliability of condition estimation is improved, but the cost increases
Solution Approach 1:
The wide-area lightning detection network serves as a cost-effective intermediary that provides comprehensive lightning data to multiple structures simultaneously. Instead of each structure bearing the full cost of sophisticated detection equipment, the centralized network distributes information to many users, dramatically reducing the cost per structure while maintaining high reliability through aggregated data from the entire network.
Solution Approach 2:
The centralized processing system serves multiple structures and multiple functions simultaneously - detecting lightning strikes, estimating conditions for various structures, and providing data to multiple users. This multi-functionality allows the system to achieve high reliability for condition estimation across many structures without proportionally increasing the cost for each individual structure.
3Area of stationary object
If a wide-area lightning detector network is used, then the coverage area is improved, but the localization accuracy decreases
Solution Approach 1:
The patent merges data from two different detection approaches: wide-area lightning detection network data and simple local detector data. By combining these complementary data sources, the system achieves both the broad coverage of the wide-area network and the precise localization capability of local detectors, resolving the contradiction between coverage area and localization accuracy.

AI summary
A lightning detection system (10) for detecting a lightning strike are provided. The system includes a lightning detector (12) in a structure susceptible to a lightning strike. The lightning detector includes a data logger (16) configured to log data indicative of a time of occurrence of the lightning strike. The system further includes memory (18) to store data collected from a wide-area lightning detection network (20). The stored data includes at least one characteristic of the lightning strike. A processor (22) may be configured to process data from the data logger relative to data collected from the wide-area lightning detection network to determine correlated data indicative of a lightning strike affecting the structure. In the event correlated data is determined, the processor may be configured to assign the characteristic of the lightning strike to the structure.
