Dynamic Exclusion Zone Adjustment for GPS Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing position monitoring systems for offenders lack flexibility in defining exclusion and warning zones, particularly in small cities or villages, where fixed zones can overly restrict movement or pose safety risks.
Innovation Solution
The system dynamically adjusts the size of exclusion and warning zones based on the distance and travel time of mobile support units from the zones, using GPS sensors and traffic information to ensure timely intervention while maximizing the offender's freedom and protecting the victim's safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed exclusion zones are defined for monitored persons, then the monitored person's freedom of movement is restricted, but safety for the protected individual is improved
Solution Approach 1:
The patent implements dynamic exclusion zones that automatically adjust their spatial boundaries based on real-time distance measurements to mobile support units. Instead of fixed static zones, the system continuously modifies zone parameters (radius, position) according to the proximity of police vehicles or other support units, allowing the monitored person's freedom of movement to expand when support units are nearby while maintaining safety constraints when they are absent.
2Reliability
If large exclusion zones are defined to ensure safety, then the monitored person's freedom of movement is overly restricted, but the protected individual's safety is enhanced
Solution Approach 1:
The system dynamically changes the parameters of exclusion zones (spatial extent, boundary position, radius) based on the distance to mobile support units. When support units are far away, larger exclusion zones provide safety margins; when support units approach, the zones automatically shrink or shift, allowing the monitored person greater freedom of movement while maintaining appropriate safety buffers.
3Adaptability or versatility
If mobile support units are positioned far from exclusion zones, then the monitored person has more freedom of movement, but response time to potential threats increases
Solution Approach 1:
The system continuously monitors the distance between mobile support units and exclusion zones, using this feedback to dynamically adjust zone parameters. When support units are detected at greater distances, the system compensates by adjusting exclusion zone boundaries to maintain appropriate safety margins, while automatically allowing expanded freedom of movement when support units are positioned close by, thus balancing response time requirements with freedom of movement.

AI summary
The present invention provides a monitoring system (1, 100, 200) for monitoring a first person's position. The monitoring system (1, 100, 200) comprises a first position sensor (6, 105, 203) configured to monitor the first person's position and provide a respective first position signal (7, 204). Further, the monitoring system (1, 100, 200) comprises a position monitor (8, 205) configured to monitor based on the first position signal (7, 204) if the first person (2, 101, 201) enters a spatially defined warning zone (4, 103) or a spatially defined exclusion zone (5, 104), which is a sub-zone of the warning zone (4, 103). The position monitor (8, 205) is configured to provide a warning signal (9, 206) if the first person (2, 101, 201) enters the warning zone (4, 103) and provide a disobey signal (10, 207) if the first person (2, 101, 201) enters the exclusion zone (5, 104). Finally, the monitoring system (1, 100, 200) comprises a modification unit (12), which is configured to spatially modify the warning zone (4, 103) and/or the exclusion zone (5, 104) based on the distance (13) of at least one mobile support unit (11, 112, 113, 210, 211) from the warning zone (4, 103) and/or the exclusion zone (5, 104). The present invention further provides a corresponding method.
