Streetlight Control for Emergency Response via Mobile Dispatch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency response systems, such as Blue Light Systems, are ineffective in situations where users cannot access call boxes or reach buttons due to their emergency condition, and they are costly to maintain.
Innovation Solution
A centralized streetlight management system that allows users to request assistance through a mobile device application, which can change streetlight modes to alert the public and provide location information to authorities, enabling quicker emergency response and public awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional Blue Light Systems are deployed, then emergency response capability is provided, but maintenance cost increases and accessibility is reduced
Solution Approach 1:
The patent repurposes existing streetlight infrastructure to serve dual functions: traditional illumination and emergency response signaling. The streetlight controllers are modified to receive and respond to emergency distress signals from mobile devices, transforming ordinary streetlights into emergency response nodes without requiring separate dedicated infrastructure
Solution Approach 2:
The system enables automated emergency response where streetlights autonomously change their lighting patterns upon receiving distress signals and automatically reset when emergency services arrive. This self-service capability eliminates the need for manual activation and reduces maintenance requirements compared to traditional Blue Light Systems
2Reliability
If call boxes are deployed, then emergency assistance can be requested, but accessibility is reduced when users cannot reach buttons
Solution Approach 1:
The patent replaces the mechanical button-pressing interface of traditional call boxes with a mobile application-based system. Users can trigger emergency responses through software interfaces on their smartphones, which can be activated even when physically constrained, thereby eliminating the need for direct physical contact with call box buttons
Solution Approach 2:
The mobile device acts as an intermediary between the user and the streetlight system. The application on the mobile device communicates the distress signal wirelessly to the centralized streetlight management system, which then activates the appropriate streetlights, providing a contactless interface for emergency requests
3Loss of time
If streetlights are used for emergency response, then response time is reduced and public awareness is increased, but control system complexity increases
Solution Approach 1:
The patent merges the streetlight control functionality with the emergency response system by integrating distress signal reception and lighting control within a unified centralized management system. This consolidation leverages existing streetlight infrastructure and control mechanisms, reducing the need for separate complex systems while achieving rapid emergency response
Solution Approach 2:
The system controls streetlights by changing their operational parameters (lighting patterns, brightness levels) in response to emergency signals. The centralized management system sends control signals that modify streetlight behavior from normal illumination to emergency alert modes and back, providing rapid response through parameter modification rather than physical system changes
Data Source
AI summary
A method of controlling streetlights by a centralized streetlight management system is described. The method includes receiving, from a user device, information corresponding to a request for assistance and determining, based on the information, a location of the user device. The method also includes sending, from the centralized streetlight management system, information corresponding to the location of the user device to one or more computing devices associated with an assistance-providing authority, and receiving, from the one or more computing devices associated with the assistance-providing authority, information indicating dispatch of assistance to the location of the user device. The method also includes, responsive to receiving the information indicating dispatch of assistance to the location of the user device, transmitting, from the centralized streetlight management system, one or more control signals to at least one streetlight at the location of the user device.
