Public-Safety Responder Dispatch Using 3D Location Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency services dispatch systems are inadequate for locations with altitudes above or below ground level, as they rely solely on two-dimensional coordinates, leading to responders arriving at incorrect elevations and being unable to provide services.
Innovation Solution
A system and method for dispatching public-safety responders to a three-dimensional location by using a PSAP device that receives calls with ground coordinates and altitudes, accessing a memory database of responder types with altitude ranges, and selecting the appropriate responders based on their equipment capabilities to reach the specified elevation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dispatch systems use two-dimensional ground coordinates (latitude and longitude), then the system complexity is low and ease of operation is maintained, but the accuracy of responder arrival at the correct elevation is poor
Solution Approach 1:
The patent applies dimensionality change by transitioning from two-dimensional ground coordinates to three-dimensional location data that includes altitude. The PSAP device receives and processes 3D location information from mobile devices, enabling accurate dispatch of responders to specific elevations such as upper floors of buildings or underground facilities, thereby resolving the limitation of traditional 2D coordinate systems.
2Reliability
If dispatch systems include altitude information and responder equipment capabilities, then the accuracy of responder selection improves, but the device complexity and data processing requirements increase
Solution Approach 1:
The patent implements parameter changes by incorporating altitude as an additional parameter in the location data and by considering responder equipment capabilities as filtering criteria. The PSAP device compares the incident altitude with the equipment capabilities of available responders (such as helicopter availability or rope access equipment) to automatically select the most appropriate responder, thereby improving selection accuracy while managing system complexity through automated parameter-based matching.

AI summary
A device, system and method for dispatching public-safety responder types to a three-dimensional location is provided. A device: receives a call and an associated location including ground coordinates and an altitude; and selects a primary public-safety responder type from a plurality of public-safety responder types associated with corresponding altitude ranges that are at or near the ground coordinates, the primary public-safety responder type associated with a corresponding altitude range that includes the altitude of the associated location of the call. The device one of automatically dispatches the primary public-safety responder type to the ground coordinates and the altitude associated with the call; and provides, to a public-safety answering point associated with the ground coordinates, an electronic suggestion to dispatch the primary public-safety responder type to the ground coordinates and the altitude associated with the call.
