发动机系统数据质量评价模型的思考

Consideration on Engine Test Data Quality Evaluation Model

随着发动机排放升级,汽车及发动机的结构复杂性、控制智能化程度也是飞跃提升,发动机系统也产生了越来越多的信息数据,信息数据具备了来源多样化、信息大量化、实时传输性的特征,要充分利用好这些数据,真正实现大数据应用,就需要做好系统数据的质量评价。从发动机的数据特征出发,建立了基于质量守恒原理的系统数据质量评价模型,该模型已在当前发动机领域应用。

With the upgrading of engine emission Standards,the complex structure of the Automobile and the improves of intelligent control,the engine system also produces more and more information data,which has the characteristics of diversified sources,large amount of information and real-time transmission.To make full use of these data and truly realize the application of big data,we need to do a good job in the quality of engine test data quantity evaluation.Starting from the engine test data data characteristics,this paper puts forward the engine test data quality evaluation model based on mass conservation,and expounds some preliminary applications of the model.
