Design And Implementation Of Taiyuan City Of The Vehicle Exhaust Monitoring System

The number of motor vehicles with the explosive growth of the urban population, per capita Road, small area, public transportation development lags behind, which makes air quality worse and worse. Environmental monitoring shows that the motor vehicle exhaust emissions are a major source of urban air pollution, nitrogen oxides, PM2.5 increase in our province haze weather and vehicle emission is directly related to the. According to statistics, every year the province’s vehicle amount over the previous year growth of 14%, transfer and cancellation of 3.8%, nitrogen oxides emissions showed a trend of rapid growth.This system on consulting the domestic and foreign present situation of a large number of system at the same time, analysis the feasibility of the system development, and has carried on the system of field research and demand analysis, through the analysis of the monitoring service, to build the overall framework of the system, use case model, state model of the system, in the system of network deployment is realized based on the VLAN, convenient system center and all regions of the data connection, in the database design of the system, using the ER diagram of the system database model building, reduce the data redundancy, data structure optimization, the ultimate realization of environmental monitoring center, data statistics, decision analysis, public inquiries, video monitoring system, finally, the functional test on the system using the black box testing, test case design part and to test the system, ensure the normal operation of the system in a stable environment.On the motor vehicle exhaust gas monitoring system construction and implementation process, to achieve the effective integration of supervision and management information. In the national motor vehicle exhaust monitoring industry in Taiyuan City, based on information technology of automobile exhaust gas monitoring and management of city, automobile tail gas monitoring system described in this paper makes the exhaust emission management local area rose to a new height, for emissions monitoring throughout the country to provide a more scientific basis.
