Solution Overview
Problem
Existing security systems face challenges in quickly responding to threats within secured areas, as guards may be patrolling one part of the area when a threat arises in another, necessitating improved methods for evaluating threats and allocating resources effectively.
Innovation Solution
A security system that includes sensors, CCTV cameras, a control panel, and portable wireless devices with a graphical user interface, allowing guards to track the location of objects and personnel in real-time using a building information model (BIM) file, enabling them to respond promptly to threats by displaying geographic locations on a map and providing emergency paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If guards patrol manually throughout the secured area, then they can physically respond to threats, but the response time is delayed when threats occur in distant locations
Solution Approach 1:
The patent introduces a central control panel as an intermediary that receives sensor data and camera feeds, processes threat information, and directs guards to specific locations. This mediator eliminates the need for guards to randomly patrol, enabling direct navigation to threats and significantly reducing response time.
Solution Approach 2:
The system implements continuous feedback loops where sensors and cameras monitor the secured area, detect threats, and immediately notify the control panel. The control panel then provides real-time feedback to guards about threat locations, enabling rapid response. This closed-loop feedback system ensures threats are detected and responded to without delay.
2Reliability
If multiple sensors and cameras are deployed throughout the secured area, then threat detection capability is improved, but system complexity and cost increase
Solution Approach 1:
The patent combines multiple sensors (motion detectors, smoke detectors, etc.) and cameras into a single integrated security system managed by one control panel. This merging approach maintains high threat detection reliability through comprehensive monitoring while reducing overall system complexity by centralizing control and data processing in one location.
Data Source
AI summary
An apparatus is provided that includes a user input of a security system receiving a respective identifier for each of a plurality of objects tracked within a secured area having a plurality of geographically separate spaces and a processor of the security system detecting entry of one of the plurality of objects into one of the plurality of geographically separate spaces via an access controller associated with the one of the plurality of geographically spaces, determining a geographic location of the one of the plurality of objects based upon detecting the entry, retrieving a map of the secured area along with a track of the one of the plurality of objects through the secured area, and displaying the geographic location of the one of the plurality of objects on the map through one of a portable handheld device, a monitoring station, and other possible human machine interface devices.
