Dynamic Location Reporting Frequency Control for Paving Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paving system coordination methods, such as those described in U.S. Patent Application Publication No. 2013/0290062, do not dynamically adjust the frequency of location information reporting based on truck speed, distance to the worksite, expected travel time, or geofence proximity, leading to inefficient resource usage and potential network bandwidth waste.
Innovation Solution
A method and system that dynamically control the reporting frequency of location sensors on haul trucks and other paving system components based on distance to geofences, expected travel time, and speed, adjusting the frequency to optimize location information transmission and reduce unnecessary data transmission.

Engineering Contradiction Analysis
1Measurement precision
If location information is provided at a high default reporting frequency, then location accuracy is improved, but network bandwidth and processor resources are wasted when high accuracy is not required
Solution Approach 1:
The system dynamically adjusts the reporting frequency of location sensors based on real-time conditions such as truck speed, distance to worksite, and proximity to geofences. When the truck is far from the worksite or moving at high speed, the reporting frequency is reduced. When the truck approaches the worksite or slows down, the frequency increases to provide more accurate location data when needed.
Solution Approach 2:
The system changes the parameter of reporting frequency based on multiple conditional parameters including distance to geofence, truck speed, and expected travel time. The controller modifies the reporting frequency parameter dynamically rather than using a fixed default value, optimizing the balance between location accuracy and resource consumption.
2Loss of energy
If location information is provided at a low default reporting frequency, then network bandwidth is conserved, but location tracking accuracy suffers when the truck is near the worksite
Solution Approach 1:
The system transitions from a static low reporting frequency to a dynamic adjustment mechanism that increases frequency when the truck enters critical zones near the worksite. This ensures accurate location tracking is maintained during critical operations while conserving bandwidth during less critical phases of the journey.
Solution Approach 2:
The system proactively increases reporting frequency before the truck enters critical zones by monitoring distance to geofences and predicting arrival time. This preliminary adjustment ensures that high-accuracy location data is available in advance when the truck approaches the worksite, preventing data gaps during critical operations.
3Device complexity
If a fixed reporting frequency is used for all locations, then system complexity is reduced, but resource efficiency decreases due to unnecessary data transmission
Solution Approach 1:
The system introduces multiple adjustable parameters (distance to geofence, truck speed, expected travel time) that control the reporting frequency. This parameter-based approach allows the system to adapt to different operational contexts without requiring complex manual configuration, achieving high resource efficiency through automated parameter-driven adjustments.
Solution Approach 2:
The system autonomously adjusts reporting frequency based on real-time sensor data and pre-programmed geofence information. The controller automatically determines when to increase or decrease reporting frequency without external intervention, enabling the system to self-optimize resource usage based on its own operational state and environmental conditions.

AI summary
A method includes receiving first location information at a first reporting frequency, the first location information being generated by a location sensor and indicating a first location of a paving system component. The method also includes determining that a distance between a second location of the paving system component and a first geofence is less than or equal to a distance threshold. The method further includes controlling the location sensor to provide second location information at the first reporting frequency, and receiving third location information at the first reporting frequency. In such a method, the third location information indicates a third location of the paving system component. The method also includes determining that the third location is within the first geofence, and controlling the location sensor to provide fourth location information at a second reporting frequency greater than the first reporting frequency.
