| The report of the Nineteenth National Congress of the Communist Party of China pointed out that "we must strengthen environmental governance" and "clean water and green mountains are equal to mountains of gold and silver".Today,with the party and the country paying more and more attention to environmental governance,air quality pollution is still a prominent issue,of which automobile exhaust emissions are an important factor.The continuous smog has created increasingly endangers the living environment of human beings and the ecological environment of the earth.Carbon dioxide(CO2),sulfide SOx(SO and SO2),and nitrogen oxides NOx(NO and NO2)in automobile exhaust cause the atmospheric problems such as the greenhouse effect,ozone layer destruction and serious acid rain.It also affects our bodies and creates great health hazard.Nowadays,environmental protection authorities are constantly organising forces to strengthen inspections and prohibit the use of vehicles.However,due to the strong mobility of vehicles and the incomprehensive administrative inspection measures,this task is very difficult.In response to the above-mentioned pain points of the enforced inspections by government,the detection solution proposed in this paper is an Automobile Exhaust Gas Detection system designed and researched based on the Internet of Things technology.It is a detection device that can be easily installed at the rear of cars,and then transmit the data wirelessly to the cloud serve where all relevant data is stored.The system can quickly receive and print the detection data from the cloud server through the application software installed on mobile phones,so that it can easily check the NOx emissions of cars,while supporting the PC terminals to receive data,facilitating the rapid inspections of the environmental protection departments.This detection system can provide a fast and comprehensive solution,with the following characteristics:First,the detection range is relatively wide.It can detect on roads in mountainous regions,semi-mountainous regions and on plains.Second,the detection is fast.It can quickly detect andprint test data by applying advanced technologies such as mobile internet technology,NOx sensors,cloud servers,and mobile APPs.Third,the system is stable and reliable.Since the server is developed within the B / S framework and its background program is developed by JAVA using standardised codes and My SQL database,it effectively guarantees stable operation of the system,and therefore has considerable value in promoting it. |
