Wireless Alert System with Zoning and Central Station
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack the ability to automatically notify individuals about alarm conditions detected in remote monitored zones, requiring manual alerting and failing to transmit notifications to portable devices outside the monitored area.
Innovation Solution
A system comprising a wireless infrastructure, a central station with control circuitry and monitoring software, and portable/wireless devices that configure zones, compute alarm levels, and send alert notifications to associated devices based on ambient and location data, including pre-alerts for approaching individuals and emergency responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stand-alone portable detectors are used to detect alarm conditions, then the detector can provide notification to the individual wearing or carrying it, but only individuals in the zone where the alarm condition is detected are alerted and manual alerting is required for remote zones
Solution Approach 1:
A central station acts as an intermediary between portable detectors and individual devices. The central station receives alarm data from detectors in multiple zones, processes the information, and automatically transmits notifications to appropriate portable devices, eliminating the need for manual alerting while maintaining reliable detection
Solution Approach 2:
Multiple portable detectors across different zones are merged into a unified networked system through the central station. This combination allows the system to function as a comprehensive monitoring network that can automatically notify individuals about alarm conditions in any zone, not just the local zone
2Loss of information
If wireless portable devices with location tracking are used, then the location of an individual can be tracked, but there are no systems for notifying an individual about remote alarm conditions via portable device
Solution Approach 1:
The system continuously receives feedback from portable devices including location data and alarm detections. This feedback loop enables the central station to automatically determine which individuals are in or near affected zones and send appropriate notifications, creating an automated remote notification system
Solution Approach 2:
The system performs preliminary actions by continuously tracking individual locations and pre-positioning notification capabilities. When an alarm occurs, the system can immediately notify the appropriate individuals based on their tracked locations, eliminating the need for manual alerting procedures

AI summary
A system and method of monitoring zones for alarm conditions and automatically alerting individuals in a plurality of zones about the safety of a particular zone is provided. The method includes providing a site map of a predefined area, configuring a plurality of zones in the predefined area, receiving ambient condition data and location data from a plurality of wireless devices located in the predefined area, computing an alarm level for each zone in the plurality of zones based on the received ambient condition data and location data, and transmitting alert notifications to the plurality of wireless devices. The alert notification sent to each wireless device is based on the computed alarm level of the zone in which that wireless device is located relative to the computed alarm level of the other zones in the plurality of zones.
