Problems solved by technology

[0003] The present invention mainly solves the problem that the original automobile exhaust analysis equipment can only measure a certain type of content in the gas, and can only obtain a limited number of data at the same time, and cannot simultaneously obtain various gas content concentrations of automobile exhaust and various exhaust gases. Parameters, such as flow, pressure, etc., it is difficult to make a comprehensive and perfect judgment on the exhaust gas of the vehicle, the detection ef

Abstract

The invention relates to an intelligent wireless vehicular embedded analytical equipment for automobile exhaust, which includes housing with gaseous current alley way, central processing element and wireless transfers unit electrically connects with central processing element set in, the wireless transfers unit wireless connects with wireless vehicle speed sensor set at the automobile. In the gaseous current alley way, there sets gas pressure sensor which electrically connects with central processing element, nitrous oxides feeler unit, gas flow meter, oxygen gas feeler unit, heat meter, oxycarbide and oxyhydride feeler unit. This invention can get the concentration values of oxygen gas, nitrous oxides, oxycarbide and oxyhydride contained in automobile exhaust and the flow, pressure, temperature and other parameters of automobile exhaust at one time, which makes comprehensive and perfect judgment on the exhaust discharged by the automobile, obtains the mass discharged values of automobile exhaust, and wirelessly sends to detecting person or unit in long distance, and the detecting efficiency of the invention is high.

Description

technical field [0001] The invention belongs to the field of gas monitoring, in particular to an intelligent wireless vehicle-mounted embedded vehicle exhaust analysis device. Background technique [0002] The tail gas emitted by automobiles mainly contains CO2, CO, CH compounds and NO compounds. With the rapid growth of motor vehicles, more and more CO2, CO, CH compounds and NO compounds will be emitted into the air, causing the greenhouse effect, etc. The negative impact is also becoming more and more serious, which has seriously threatened the survival of human beings. Therefore, the exhaust gas emission standards we have formulated are becoming increasingly stringent. However, traditional gas analyzers can only measure certain types of exhaust gases, and can only obtain a limited number of data at the same time. They cannot simultaneously obtain various gas content concentrations of automobile exhaust and various parameters of exhaust gases, such as flow rate. , pressu...
