Abstract

The embodiment of the invention provides a data sequence correlation evaluation method, device and system, and the method comprises the steps: obtaining a first data sequence, obtained by a monitoringplatform, from a vehicle-mounted terminal, wherein the first data sequence is obtained by the vehicle-mounted terminal based on monitoring data collected by at least one vehicle monitoring sensor ona reference vehicle; obtaining a second data sequence obtained through an OBD reading device of the vehicle-mounted self-diagnosis system, wherein the second data sequence is the monitoring data readby the OBD reading device from the vehicle monitoring sensor, and the types of the monitoring data include the vehicle speed, the engine rotating speed, the air inlet flow, the fuel flow and / or nitricoxide; obtaining the relative delay time between the first data sequence and the second data sequence according to the cross-correlation function of the first data sequence and the second data sequence, obtaining a correlation coefficient, and accurately evaluating the correlation of the data sequences.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a method, device and system for evaluating the correlation of data sequences. Background technique [0002] With the tightening of heavy-duty vehicle emission standards and regulations, remote monitoring vehicle-mounted terminals for heavy-duty vehicles have gradually begun to be used. Relevant regulations require that heavy-duty vehicles need to collect specified monitoring data and upload them to the monitoring platform, and ensure the accuracy of the uploaded monitoring data. . However, there is a data inconsistency between the data received by the monitoring platform and the data collected by the OBD reading device. [0003] Therefore, how to accurately evaluate the correlation of the data sequence and improve the accuracy of the data collected by the monitoring platform and collected by the vehicle terminal has become an urgent problem to be solved.
