车载式环境监测系统的设计

Design of Vehicular Environmental Monitoring System

为了及时有效的监测环境,提供有利的环境数据,设计了一种车载式环境监测系统,通过噪声传感器、粉尘传感器及气象传感器采集环境中的噪声、扬尘(PM2.5和PM10)及气象(风速、风向、雨量、气压、温度和湿度)参数,利用STM32F103的主控板进行数据处理,再通过WCDMA WIFI路由器传输将得到的环境数据上传,最后通过相机字符叠加、LED屏幕或平板电脑进行数据发布。此外,本系统附加了报警指示灯的功能和视频监控设备周围环境的功能。该系统环境数据采集稳定,实时性较高,可应用于移动式监测,是对现有定点监测的有效补充。

In order to monitor environment timely and effectively as well as provide favorable environment data, this paper designs a vehicular environmental monitoring system. The noise, dust, and meteorological sensor is used to gather noise, dust （PM2.5 and PM10） as well as meteorological parameters （wind speed and direction, rainfall, air pressure, temperature and humidity）, which are processed by using the master control board of STM32F103 series chip. Then, the data obtained are transmitted through the WCDMA WIFI router, which are posted via camera character overlays, LED screens or tablet computers. In addition, the system has the function of alarm indicator and video surveillance. With stable performance in collecting environmental data, the system can be applied to mobile monitoring in real time, which is an effective supplement to the existing fixed point monitoring.
