Abstract

The invention belongs to the technical field of processing of engine exhaust temperature data acquired by a thermocouple in an engine compartment, and particularly relates to a collected data processing method, which comprises the following steps of: identifying abnormal data and non-abnormal data in colleced data; filtering abnormal data in the collected data by a first filtering coefficient to obtain a corresponding filtering value; and filtering non-abnormal data in the collected data by using a second filtering coefficient to obtain a corresponding filtering value, wherein the first filter coefficient is smaller than the second filter coefficient.

Description

technical field [0001] The application belongs to the technical field of engine exhaust temperature data processing collected by thermocouples in the engine compartment, and in particular relates to a data collection processing method.
