Wandering Notification Server Dynamic Area Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wandering notification systems are ineffective when the person to be protected does not carry a communication terminal, and they struggle to detect and respond to wandering behavior outside specific facilities, with difficulties in installing dedicated receivers over wide areas.
Innovation Solution
A wandering notification server that records personal and notification area information, receives wandering information from detection apparatuses, and transmits personal information to notification terminals within a dynamically adjusted notification area, including both neighborhood and external terminals, to ensure quick and accurate protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a surveillance system uses Bluetooth communication terminals carried by the person to be protected, then the system can detect the person's location, but the system becomes ineffective when the person removes the terminal or changes clothes
Solution Approach 1:
The patent introduces an intermediary detection apparatus (such as a camera or sensor system) that detects the person without requiring direct contact or carrying of communication terminals. This intermediary system can observe the person's location and appearance independently of whether they are wearing a terminal, thus resolving the contradiction between detection reliability and adaptability to the person's actions.
Solution Approach 2:
The system creates a digital copy or representation of the person through detection apparatus (camera images, sensor data) rather than relying on physical terminals carried by the person. This copying approach allows continuous monitoring regardless of whether the person is wearing any communication device, maintaining detection reliability while adapting to the person's freedom of movement.
2Reliability
If the system is designed for specific facility monitoring, then detection is effective within the facility, but the system cannot detect the person when they leave the facility
Solution Approach 1:
The detection apparatus is designed with universal functionality to operate both within and outside the facility boundaries. The system can switch between different detection modes or use multiple detection apparatus distributed in different locations, enabling it to maintain detection effectiveness whether the person is inside or outside the facility, thus expanding detection range while preserving reliability.
Solution Approach 2:
The system transitions from a single-location detection approach to a multi-dimensional detection network that spans both indoor and outdoor environments. By adding spatial dimensionality and deploying detection apparatus in multiple locations (including outside the facility), the system achieves comprehensive coverage that works whether the person is inside or outside the facility boundaries.
3Area of stationary object
If dedicated receivers are installed over a wide area, then detection coverage is expanded, but installation difficulty increases
Solution Approach 1:
Instead of installing a single comprehensive receiver system, the patent segments the detection function into multiple distributed detection apparatus (such as cameras or sensors) placed at key locations. This segmentation allows the system to achieve wide-area coverage through multiple simple units rather than one complex installation, making the overall system easier to deploy while maintaining extensive detection coverage.

AI summary
A wandering notification system (1) to which the present invention is applied is provided with a management server (2), a neighborhood terminal (3), and an external terminal (4). A wandering information transmission unit (10) of the management server (2) extracts a plurality of neighborhood terminals (3) for making known information with a notification area in a certain range, set on the basis of an address of a person to be protected who starts wandering, as a reference. Further, the wandering information transmission unit (10) receives positional information of the extracted neighborhood terminals (3) and transmits personal information and wandering information of the person to be protected to the neighborhood terminal (3) that exists within the notification area.
