Bluetooth Evacuation System for Rapid Personnel Accounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing evacuation systems face challenges in quickly and accurately determining the number of people and identifying missing individuals during building evacuations, especially in complex scenarios with multiple assembly points, due to difficulties in locating individuals within the building.
Innovation Solution
A Bluetooth-based evacuation system that uses portable registration units and Bluetooth pendants with unique identifiers, allowing for automatic detection and tracking of individuals within a danger area, enabling efficient data collection and communication of their location and status without the need for pairing, and facilitating network communication between registration units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional evacuation systems use manual headcounting and identification methods at assembly points, then the system structure remains simple, but the time required to determine the number of people and identify missing individuals increases significantly
Solution Approach 1:
The system performs preliminary registration of all individuals in the building before evacuation occurs. Bluetooth tags are pre-configured with identification data and locations are pre-mapped. When evacuation is triggered, the system already has baseline data to quickly compare against current status, enabling rapid identification of missing persons without manual headcounting.
Solution Approach 2:
The patent replaces manual mechanical headcounting and identification processes with automated Bluetooth-based detection systems. Registration units automatically scan for Bluetooth tags and identify individuals using their unique identifiers, eliminating the need for manual verification and significantly reducing the time required to account for all persons.
2Measurement precision
If evacuation systems track individuals throughout the entire building including restrooms and canteens, then identification accuracy improves, but system complexity and difficulty of locating individuals increases
Solution Approach 1:
The building is divided into multiple zones with separate registration units deployed in different areas. Each registration unit independently tracks individuals in its zone, and the central system aggregates data from all zones. This segmentation allows comprehensive tracking without requiring a single complex system to manage the entire building, reducing overall complexity while maintaining precision.
Solution Approach 2:
Bluetooth tags serve as intermediaries between individuals and the registration system. Instead of requiring direct communication between registration units and persons, the Bluetooth tags mediate the interaction, simplifying the system architecture while enabling precise location tracking throughout the building including difficult-to-monitor areas like restrooms and canteens.
3Reliability
If Bluetooth tags require pairing with registration units for identification, then connection reliability improves, but the number of people that can be tracked simultaneously is limited
Solution Approach 1:
Bluetooth tags are designed to autonomously broadcast their identification data without requiring pairing or manual configuration. Registration units passively receive and process these broadcasts, eliminating the need for time-consuming pairing procedures. This self-service approach allows the system to track an unlimited number of individuals simultaneously while maintaining reliable identification through the tags' inherent broadcasting capability.

AI summary
A method for operating an evacuation system to support an evacuation, in particular the evacuation of a building, comprising the following steps: a. Providing a Bluetooth-based detection system comprising at least one registration unit positioned at the workplace and at least one Bluetooth tag carried by the person to be detected, the Bluetooth tag containing a data set with a unique identifier for identifying the person; b. Initiating an alarm due to an evacuation within a danger zone; c. Providing one or the registration unit at a location outside the danger zone; d. Scanning the registration unit for at least one, in particular a plurality, of Bluetooth tags matched to the registration unit; e. Transmitting a signal, in particular comprising the data set, by the respective Bluetooth tag; f.g. Receipt of the signal by the registration unit, with simultaneous determination of the time of reception by means of a time recording of the registration unit and/or the position of the person, including geographical data regarding the location of the registration unit; and g. Comparison of the data determined in step d) with a data log comprising a data record created before the evacuation event, including a last recorded time and a last recorded location of the person in the danger zone before the initiation of the evacuation event according to step b); and h. Updating the data log.
