Background
In recent years, the automobile keeping quantity in China is increased sharply, and the problem of pollutant emission of tail gas is also intensified. Research and analysis show that the harmful components in the tail gas discharged by the automobile reach more than 260 items, the harmful components not only contain harmful gases such as carbon monoxide, but also contain high-divergence micro-particles such as hydrocarbons, lead and mercury heavy metals and the like, the harm to the human body is serious, a blood system, a respiratory system, a lymphatic system and the like can be eroded by the harmful components, the harm to infants is huge, and even a genetic system is probably influenced. Automobile exhaust emission becomes an important factor of air pollution, is the most main source of most provinces and urban air pollution, and becomes an environmental pollution problem which is more and more concerned by the social public.
China mainly detects automobile exhaust emission pollution and assists manual detection of mobile set points in preventing and monitoring automobile exhaust emission pollution. The former has a long-term detection blind spot in a detection period, and the latter is influenced by a plurality of factors such as a detected road section, a traffic condition, a detection frequency and the like. In recent years, a small number of telemetry systems have been deployed in a small number of cities, but such systems have had little effect when the roads are busy. Currently, monitoring of automobile exhaust emissions by environmental regulatory authorities still faces serious challenges.
