【摘要】：随着全国机动车数量爆炸式增长,城市人口大、人均道路面积小、公共交通发展滞后,使得空气质量每况愈下。环境监测表明,机动车尾气排放是城市空气污染的主要来源,我省阴霾天气增多和机动车排放的氮氧化物、PM2.5直接相关。据统计,每年全省机动车保有量比上一年增长14%,转出及注销3.8%,氮氧化物排放呈快速增长趋势。本系统在查阅大量的国内外系统现状的同时,分析了系统开发的可行性,同时对系统进行了现场调研和需求分析,通过对监控业务的分析,构建系统的整体框架,系统的用例模型、状态模型,在系统网络部署上实现了基于VLAN的方式,方便系统中心和各个地区的数据连接,在对系统的数据库设计时,利用ER图对系统的各类数据库表格建立模型,减少数据冗余,优化数据结构,最终实现了监控中心,环保数据统计,决策分析,公众查询,视频监控等系统,最后,利用黑盒测试对系统进行功能性测试,同时设计部分测试用例对系统进行性能测试,保证系统在稳定的环境下正常运行。在对机动车尾气监控系统构建和实施过程中,实现了监控和管理信息的有效整合。在全国机动车尾气监控行业中,太原市以信息化技术对汽车尾气进行监控管理的城市,本文所述的汽车尾气监控系统使得本地区的尾气排放管理上升到一个新的高度,为全国的尾气排放监控提供一个更为重要的科学依据。
[Abstract]:With the explosive growth of the number of motor vehicles in China, the urban population is large, the per capita road area is small, and the development of public transport lags behind, which makes the air quality worse and worse. Motor vehicle exhaust emission is the main source of urban air pollution. The increase of haze weather in our province is directly related to the emission of nitrogen oxide PM2.5. According to statistics. Compared with the previous year, the number of motor vehicles in the province increased by 14%, the transfer and write-off of 3.8%, nitrogen oxide emissions showed a rapid growth trend. This system is looking up a large number of domestic and foreign systems at the same time. The feasibility of the system development is analyzed. At the same time, the field investigation and requirement analysis of the system are carried out. Through the analysis of the monitoring business, the overall framework of the system, the use case model and the state model of the system are constructed. In the system network deployment based on the way of VLAN, facilitate the system center and each region of the data connection, in the system database design. Using ER diagram to build up the model of all kinds of database tables of the system, reduce the data redundancy, optimize the data structure, finally realize the monitoring center, environmental protection data statistics, decision analysis, public inquiry, video surveillance and other systems. Finally, the function of the system is tested by black box test, and some test cases are designed to test the performance of the system. In the process of construction and implementation of vehicle exhaust monitoring system, the effective integration of monitoring and management information is realized. Taiyuan City with the information technology to monitor and manage the vehicle exhaust in the city, the vehicle exhaust monitoring system described in this paper makes the exhaust emission management in this area to a new level. It provides a more important scientific basis for national emission monitoring.
