车载式环境监测系统的设计

摘要

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 environ-ment data,this paper designs a vehicular environmental monitoring system.The noise,dust,and meteor-ological sensor is used to gather noise,dust (PM2.5 and PM1 0)as well as meteorological parameters (wind speed and direction,rainfall,air pressure,temperature and humidity),which are processed by u-sing 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 comput-ers.In addition,the system has the function of alarm indicator and video surveillance.With stable per-formance 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.
