Asset Tracking Unit Geofence Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Establishing and monitoring geofences for asset tracking systems is resource-intensive, especially for companies with numerous assets located at various sites, as it requires significant effort to set and maintain precise boundary definitions.
Innovation Solution
An asset tracking unit equipped with a location sensor and wireless communication capabilities determines when an asset is at a site by analyzing movement patterns and sets a geofence based on predetermined criteria, such as speed and location stability, and transmits notifications when the asset leaves the site, reducing the need for extensive resource allocation.

Engineering Contradiction Analysis
1Measurement precision
If geofences are established for each asset at every site, then asset location monitoring accuracy is improved, but resource consumption increases significantly
Solution Approach 1:
The system applies different monitoring strategies to different locations. Geofences are only established when an asset is determined to be at a site (based on movement pattern analysis), rather than continuously maintaining geofences everywhere. This local differentiation reduces resource consumption while maintaining monitoring accuracy where needed.
Solution Approach 2:
The geofence establishment is dynamic rather than static. The system continuously analyzes asset movement patterns and only establishes geofences when the asset is determined to be at a site. This dynamic approach allows the system to adapt resource allocation to actual monitoring needs, reducing unnecessary resource consumption.
2Reliability
If geofence boundaries are established based on expected asset movement, then false notifications are reduced, but the complexity of determining site boundaries increases
Solution Approach 1:
The system performs preliminary analysis of asset movement patterns to determine when an asset is at a site before establishing geofence boundaries. By analyzing speed and location stability in advance, the system prepares appropriate boundary definitions that reduce false notifications while managing complexity through structured decision-making.
Solution Approach 2:
The system uses parameter changes in asset movement (speed, location stability over time) to determine site presence. By monitoring these parameters and their changes, the system dynamically adjusts geofence establishment decisions, reducing false notifications while using standardized parameter thresholds to manage determination complexity.

AI summary
An asset tracking unit associated with an asset determines that the asset is located at a site and establishes a geofence. The asset tracking unit transmits a notification to a central dispatch that the asset is at the site. In the event that the asset moves beyond the geofence boundary, a notification is sent to the central dispatch indicating that the asset has moved. The asset tracking unit established the geofence based on pre-established boundary criteria that are stored at the asset tracking unit.
