The segmented data compression system aims to optimize driving time calculations under conditions of delayed data collection and transmission.

Abstract

This invention relates to a method of segmented data compression for the accurate calculation of real-time driving time for vehicle tracking devices, even under ideal transmission conditions or with latency. The proposed method comprises three main functional blocks: a vehicle-based data filtering and grouping block, a data processing and compression block, and a driving time calculation block. Data collected from vehicle tracking devices is grouped by vehicle identifier and normalized based on the extraction of vehicle operating state characteristics. Next, the data is processed through a backsynthesis mechanism combined with segmented compression, allowing for accurate data restructuring while improving processing efficiency. Finally, the aggregated data is fed into an optimization calculation method, thereby enabling the rapid and accurate determination of actual driving time along with related derived indicators.
