Vehicular tail gas emission diagnosis and remote monitoring method and monitoring terminal

Abstract

The invention relates to the field of diesel vehicle tail gas emission monitoring and discloses a vehicular tail gas emission diagnosis and remote monitoring method. The method includes steps: readinginformation of operating conditions of a vehicular engine, information of each ECU controller of a vehicular body, information of a vehicular sensor and information of operating conditions of vehicular own after-treatment products; reading vehicular real-time geographical location information; uploading the information of the operating conditions of the vehicular engine, the information of each ECU controller of the vehicular body, the information of the vehicular sensor, the information of the operating conditions of the vehicular own after-treatment products and the vehicular real-time geographical location information into a monitoring system platform, and storing in the monitoring terminal. The invention further provides a cloud server based vehicular tail gas emission diagnosis and remote monitoring terminal. Problems of high labor consumption and failure in uniform and comprehensive inspection and performance tracking in diesel vehicle tail gas emission inspection in the prior art are solved.

Description

technical field [0001] The invention relates to the field of diesel vehicle exhaust emission monitoring, in particular to a vehicle exhaust emission diagnosis remote monitoring method and a monitoring terminal. Background technique [0002] At present, there are 19.567 million diesel vehicles in use in China, of which diesel vehicles with China III and below emission standards account for 21.2%. The main pollutant emitted by such diesel vehicles is PM. Measures such as the transformation of National III vehicles have greatly reduced the PM concentration in the exhaust emissions of most of the National III and below vehicles. The National IV and National V diesel trucks accounted for 69.5%, and their emission pollutants are mainly NOx. At present, the national IV and National V diesel vehicles are basically equipped with SCR after-treatment systems as standard. The NOx emission of the original vehicle is reduced through the SCR after-treatment system. However, in the actual...
