Abstract

The invention discloses a TBOX-based dimension reduction system for whole vehicle operation data, solving the problem that an existing data compression method cannot meet the requirement of whole vehicle operation data analysis, and belonging to the field of data analysis and processing. According to the TBOX-based dimension reduction system, a data divider performs data segmentation on classification side vehicle operation data stored in an original signal library; a simple PCA principal component analyzer acquires the principal component of each classification side index according to the segmented data; a first aggregation calculation module obtains an index value of a principal component of each classification side index according to the principal component of each classification side index; a vehicle information basic model is updated according to the index value to obtain the basic characteristics of the vehicle per minute; a main feature selection calculation module selects a main feature from the obtained basic features according to a main index of the whole vehicle operation data; an incremental PCA principal component analyzer analyzes the principal characteristics to obtain the principal components of the principal index data influencing the whole vehicle operation data; and the principal components are aggregated by using a second aggregation calculation module to obtain secondary dimension reduction data.

Description

technical field [0001] The invention relates to a data principal component analysis system, in particular to a TBOX-based dimensionality reduction system for vehicle operation data, belonging to the field of data analysis and processing. Background technique [0002] The TBOX (Telematics Box, Internet of Vehicles system) management platform has about 50,000 vehicles online at the same time every day. The vehicles are distributed all over the country, and nearly 8TB of data are transmitted to the platform every day, with an annual increase of 2PB, including position, speed, and power. side sensor data, energy side sensor data, power supply side sensor data, vehicle operation status, alarm situation, event information and other vehicle operation data. Through big data technology, the effective principal component analysis and dimension reduction of massive vehicle operation data can quickly, stably and efficiently convert N-dimensional structured big data into the smallest dim...
