The invention discloses a particulate matter sensor analysis system and method for a diesel vehicle. The analysis system comprises a display screen, a power source, a tail gas analyzer, an industrial personal computer and a gas path system, wherein the gas path system is used for containing a to-be-tested particulate matter sensor and simulating and testing tail gas; the display screen, the tail gas analyzer, the industrial personal computer and the gas path system are in communication connection with one another; and an opening is formed in the gas path system, and the detection end of the tail gas analyzer is fixed to the gas path system through the opening so as to test tail gas in the gas path system. The analysis system can calibrate the particulate matter sensor, can adapt to various types of particulate matter sensors, analyzes the precision of the calibrated particulate matter sensor, and verifies the precision of the particulate matter sensor. Through the collected information of the particulate matter sensor, research and development personnel can conveniently carry out a preliminary test, scheme verification, control strategy effectiveness and model analysis on the performance of the particulate matter sensor.
Description
technical field [0001] The invention relates to the field of sensor equipment, in particular to a system and method for analyzing a particulate matter sensor for diesel vehicles. Background technique [0002] As we all know, diesel engine emissions contain a large amount of particulate matter, especially PM2.5, which accounts for 80% of particulate matter emissions, which will cause great harm to the environment and human health. Therefore, many researchers at home and abroad have carried out in-depth exploration and research on the particulate matter emitted by diesel engines. With the promulgation of my country's National VI Standard, the requirements for particulate matter emissions are more stringent, and the performance requirements for particulate matter sensors are even more stringent. However, in the prior art, there are many types of particulate matter sensors, and the measurement principles are quite different. The analysis systems of the particulate matter sensor...
