Abstract

A TBOX-based dimensionality reduction system for vehicle operation data solves the problem that existing data compression methods cannot meet the needs of vehicle operation data analysis, and belongs to the field of data analysis and processing. The data divider of the present invention divides the classification side vehicle operation data stored in the original signal library into data; the simple PCA principal component analyzer obtains the principal components of each classification side index according to the divided data; the first aggregation calculation module The principal component of the classification side index obtains the index value of the principal component of each classification side index; the vehicle information basic model is updated according to the index value, and the basic characteristics of the vehicle per minute are obtained; The main features are selected from the obtained basic features; the incremental PCA principal component analyzer analyzes the main features to obtain the principal components of the main index data that affect the running data of the whole vehicle; the second aggregation calculation module is used to aggregate the principal components to obtain two dimensionality reduction data.

Description

technical field [0001] The invention relates to a data principal component analysis system, in particular to a TBOX-based dimension reduction system for vehicle operation data, which belongs to the field of data analysis and processing. Background technique [0002] The TBOX (Telematics BOX, Internet of Vehicles system) management platform has about 5W vehicles online at the same time every day. The vehicles are distributed all over the country, and nearly 8TB of data is transmitted to the platform every day, with an annual increment of 2PB, including location, speed, power, etc. Side sensor data, energy side sensor data, power supply side sensor data, vehicle operation status, alarm status, event information and other vehicle operation data. Through big data technology, effective principal component analysis and dimensionality reduction for massive vehicle operation data can quickly, stably and efficiently convert N-dimensional structured big data into the smallest dimensio...
