Design of City Road Air Quality Real-Time Monitoring System

摘要:

传统的空气质量检测仪只能实时显示数据,并不具备数据传输能力；仪器采集的数据取决于传感器的质量高低,而进口的红外线空气质量分析仪价格非常昂贵；为解决这些问题,利用Arduino Uno R3单片机作为控制核心,与多种气体传感器一起组成实时监测终端；传感器采集的数据经过Arduino单片机处理后,通过VANET技术发送给车载单元或手持观测器进行实时显示；同时数据也可以通过Internet传送到控制中心；重点描述了监测终端的硬件结构与软件设计,测试结果表明本系统具有可靠性高、实时性好等优点,具有非常高的实用价值。

Abstract:

Traditional air quality monitoring detector can only display real-time data, but it doesn’t have data transmission capacity. Data collected by the instrument depends on the quality of sensors, and imported infrared air quality analyzer is very expensive. In order to solve these problems, Arduino Uno R3 is used as control core. A variety of gas sensors and Arduino Uno R3 form the real-time monitoring terminal. After data collected by sensors is processed by Arduino, it is transmitted by the technology of VANET to on-board unit or hand-held observer for real-time display. At the same time, data can be transmitted to the control center by Internet. This paper describes hardware structure and software design. The test results show that this system has the advantages of high reliability, good real-time performance and it has a very high practical value.
