Problems solved by technology

[0004] However, the research on the existing exhaust emission monitoring devices mainly focuses on the improvement of OBD and data transmission methods, without considering the possible external gas pollution during the exhaust emission process, for example, the exhaust emission of other vehicles on the road or the surrounding environment. The air quality in the environment is used for the detection of the vehicle's own exhaust emissions

Embodiment Construction

[0017] It should be noted that, in the case of no conflict, the preferred embodiment in the present application and the features in the embodiment can be combined with each other. The present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, the vehicle exhaust emission monitoring device according to the embodiment of the present invention includes a monitoring terminal and a detection terminal. The monitoring terminal includes a processing unit, and the detection terminal includes: a control unit, a power supply unit and a communication unit respectively connected to the control unit. The control unit adopts STM32F103XX series ARM processor, provides digital-to-analog conversion circuit, and realizes the analog input of the sensor. The digital-to-analog conversion circuit uses ICL7135 to convert the collected analog data into digital data. It is a four-and-a-half-bit double-integral A / D converter, wh...

Abstract

The invention aims to lower the interference of surrounding environment and cars on the monitoring for automobile exhaust gas emission, and provides a monitoring device for the automobile exhaust gas emission. The monitoring device for the automobile exhaust gas emission comprises a monitoring terminal and a detecting terminal. The monitoring terminal comprises a processing unit. The detecting terminal comprises a controlling unit, a power supplying unit and a communication unit, wherein the power supplying unit and the communication unit are connected with the controlling unit. The detecting terminal further comprises an exhaust gas collecting unit and an exhaust gas analyzing unit. The exhaust gas collecting unit comprises a gas homogenizing unit, multiple air blowing units and multiple air receiving units. The multiple air receiving units correspond to the multiple air blowing units in a one-to-one mode, and a certain distance is kept between the corresponding air blowing units and the air receiving units. According to the monitoring device, the structure of the multiple air blowing units and the multiple air receiving units is utilized, the volume of the automobile exhaust gas entering the detecting device is increased. By using the pressure difference generated by a vacuum pump, the gas concentration entering all gas detecting sensors remains unchanged. The monitoring device reduces the unsolved problem that the concentration of the exhaust gas entering the detecting device is thinned during the exhaust gas detecting process.

Description

technical field [0001] The invention relates to the technical field of automobile electronics, in particular to an automobile exhaust emission monitoring device. Background technique [0002] Research on motor vehicle exhaust pollution began in the middle of the last century in European and American countries, and in my country in the 1980s. In terms of tail gas pollution monitoring, many scholars at home and abroad have done a lot of work, not only using modern physical and chemical analysis methods to develop a large number of tail gas pollution monitoring instruments, replacing the conventional plastic bag collection method, but also establishing a system based on the characteristics of tail gas pollution. Many mathematical prediction models, combined with GIS (Geographic Information System, Geographic Information System) and RS (remote monitoring technology, remote sensing) means, have carried out empirical research in most cities.
