Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of a widely deployed and continuous operational system capable of detecting, assessing, and reacting to chemical, biological, and/or nuclear threats or accidental releases of toxins over large areas, necessitating a network of sensors for real-time monitoring and efficient data management.
Innovation Solution
A system comprising a network of communication devices equipped with sensors that report data to a data fusion center, where a processing system filters and manages reports to prevent network overload, using geographical, range, and sensor-type based controls to optimize data transmission and reduce congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a network of sensors is deployed throughout a large area for continuous monitoring, then detection coverage and monitoring capability are improved, but network load and data congestion increase
Solution Approach 1:
The patent extracts and removes redundant or low-priority report data from the sensor network transmissions. The access point filters out unnecessary reports based on criteria such as data redundancy, sensor priority, and network conditions, allowing only essential data to be forwarded to the data fusion center, thus reducing network load while maintaining detection coverage.
Solution Approach 2:
The access point serves as an intermediary between sensors and the data fusion center. It introduces a filtering mechanism that processes sensor reports before they enter the main network, acting as a buffer that prevents network congestion while ensuring reliable detection data reaches the fusion center.
2Loss of information
If all sensor reports are forwarded to the data fusion center, then data completeness is improved, but network congestion and processing load increase
Solution Approach 1:
The patent applies local quality by making the access point intelligent with filtering capabilities. Different types of sensor data are treated differently based on their importance and characteristics. Critical sensor reports are forwarded completely, while non-critical or redundant reports are filtered out, creating a quality-based data transmission system that reduces processing load while maintaining essential data completeness.
3Speed
If sensor reporting frequency is increased for real-time monitoring, then response time to threats is improved, but network load and energy consumption increase
Solution Approach 1:
The patent implements periodic action by having sensors report at different frequencies based on their priority and the current situation. Critical sensors or sensors detecting anomalous conditions increase their reporting frequency, while normal sensors maintain lower reporting rates. This periodic, adaptive reporting reduces overall network load and energy consumption while maintaining fast response capability when needed.
