GPS Event Segmentation for Fleet Speed Monitoring

The system segments GPS event data into distinct categories (speed events, location events, engine events, etc.) and stores them in a structured database format with separate fields for each event type. This segmentation allows complex fleet monitoring data to be organized into manageable, queryable units that can be analyzed independently while maintaining overall system reliability.

The patent introduces an on-board unit as an intermediary device that collects GPS data from multiple vehicles and transmits it to a central host system. This intermediary handles data preprocessing, filtering, and initial analysis, reducing the complexity burden on the central system while ensuring reliable fleet-wide monitoring capability.

The system performs preliminary analysis of GPS event data by pre-calculating and storing key operational metrics (such as speed averages, route deviations, and engine performance indicators) in the database alongside raw GPS data. This preliminary processing ensures that when fleet performance evaluation is needed, pre-computed metrics are immediately available without requiring real-time recalculation, thus reducing processing time while maintaining comprehensive metrics availability.

The patent replaces complex real-time computational analysis with database-based retrieval of pre-stored operational metrics. Instead of performing heavy computational operations when metrics are needed, the system substitutes this with efficient database queries that retrieve previously calculated values, significantly reducing processing time while preserving complete operational information.
