Embodiment Construction

[0079] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0080] In related technologies of vehicle exhaust emission road testing, a single particle sensor is usually used to detect particulate matter in the collected vehicle exhaust gas, and then the detected data is used as the particle emission data of the vehicle. However, there are certain differences in the concentration range (that is, the particle concentration range range) and the particle size range (that is, the particle size detection range) that different particle sensors can detect, and different vehicles emit emissions under different driving stages. There are also differences in particle number concentration (or particle mass concentration) and parti...

Abstract

The present disclosure relates to a particle detection method, device and exhaust gas detection system. The method includes: during the driving process of the vehicle to be tested, a plurality of target sensors assembled in the particle detection device contained in the exhaust gas detection system simultaneously discharge the vehicle to be tested. According to the vehicle driving information of the vehicle to be tested to determine its driving state; according to the driving state, the vehicle driving information and the pre-trained target detection result prediction model, the above-mentioned multiple target sensors collect Data fusion is performed on the detected particulate matter detection data to obtain the particulate matter emission data of the vehicle under test during driving. It can simultaneously detect the particulate matter emission of the vehicle through multiple sensors during the driving process of the vehicle, and fuse the detection data according to the driving condition of the vehicle to improve the accuracy of the particulate matter emission detection results during the vehicle exhaust emission road test.

Description

technical field [0001] The present disclosure relates to the field of vehicle environmental protection detection, and in particular, to a particle detection method, device and exhaust gas detection system. Background technique [0002] The emergence of vehicles has promoted the development of human civilization, and the development of the vehicle industry and vehicle transportation industry has strongly promoted the development of the world economy and greatly improved people's travel conditions. However, in recent years, the world's vehicle industry has developed beyond the norm, and the number of vehicles has exceeded 1 billion. With the sharp increase in the number of vehicles, the environmental pollution caused by them has become more and more serious. Vehicle exhaust contains more than 200 harmful substances, including CO (carbon monoxide) gas, CO 2 (carbon dioxide) gas, NO x (nitrogen oxides) gas, NH 3 (ammonia) and particulate matter are the main pollutants. Among...
