Cell-Based Weather Alert Distribution via Wireless Transmitters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current weather reporting systems, especially for severe weather conditions like tornadoes, often fail to provide real-time, site-specific information to travelers, as they rely on pre-trip forecasts and lack detailed location data, leading to insufficient warning for safe travel or property protection.
Innovation Solution
A system that divides a geographic area into cells, analyzes weather conditions, and transmits relevant alerts to wireless transmitters with known locations, which then broadcast the information to all devices within their range, eliminating the need for device location tracking and using SMS for direct alerts to remote units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If weather information is broadcast to all devices in a coverage area, then all users receive relevant site-specific alerts, but the system complexity increases due to need for transmitter location management
Solution Approach 1:
The patent uses wireless transmitters with known locations as intermediaries between the weather information source and end users. The transmitters receive weather data and automatically broadcast it to devices in their coverage areas, eliminating the need for direct device-location tracking while ensuring site-specific alert delivery.
Solution Approach 2:
The system allows wireless transmitters to autonomously manage their own coverage areas and automatically broadcast weather alerts without requiring central coordination or complex device tracking. Each transmitter independently handles alert distribution to devices within its range.
2Measurement precision
If device location tracking is implemented to provide site-specific weather alerts, then alert precision improves, but the complexity and energy consumption of the system increases
Solution Approach 1:
Instead of tracking device locations to determine which devices should receive alerts, the system inverts the approach by using known transmitter locations to determine which alerts should be broadcast to which coverage areas. This eliminates the need for continuous device location tracking while maintaining site-specific alert precision.
Solution Approach 2:
The system changes the reference frame from device-centric location tracking to transmitter-centric coverage area definition. By using fixed transmitter locations as the reference points, the system achieves location-based alert distribution without requiring dynamic device position monitoring.
3Loss of time
If real-time weather data is transmitted to all devices, then alert timeliness improves, but information loss occurs when devices are outside coverage areas
Solution Approach 1:
The system segments the service area into multiple coverage zones, each associated with a specific wireless transmitter. This segmentation ensures that weather alerts are efficiently distributed to relevant devices in each zone without requiring universal transmission to all devices, reducing both delay and information loss.
Data Source
AI summary
The present system and methods provides for distribution of weather and other environmental information to remote users within a wireless transmitter coverage area. The system and method assigns meteorological data to a plurality of cells, each corresponding to a communication range of a wireless transmitter. The data is then distributed by the appropriate wireless transmitter to all users within its coverage area. The system and method does not distribute information to a particular user based upon a known communication address, user profile, or identification, but rather is directed to any user falling within the communications range of the wireless transmitter. By indiscriminate distribution of reportable events, the system provides timely, site-specific information without requiring the location of the remote units.
