环境质量监测控制系统研究

Research on environmental quality inspection and control system

世界卫生组织的统计资料表明,由于装修房屋引发的环境污染,导致全球每年10万人死于哮喘。为了解决家庭环境污染问题,文章设计了一种环境质量监测控制系统,该系统采用STM32做主控芯片,使用传感器采集环境中的温湿度、光照强度、CO_(2)和TVOC浓度等参数数据。该系统采集参数并与设定的参数阈值进行对比,单片机判断是否开启相应的反馈补偿模块,以保证环境内的各参数数据处于相对稳定状态;最后单片机通过无线模块将数据发送给上位机,同时上位机可以对下位机发送控制命令,实现对整个环境的闭环控制。系统经过测试表明:当前测试环境内的各项参数趋于稳定,环境状态良好,对温度、湿度、光照强度、CO_(2)浓度和TVOC浓度等参数进行了检测和调控,基本达到了系统设计要求。

According to the World Health Organization,100000 people worldwide die of asthma every year from pollution caused by home renovations.In this paper,an environmental quality monitoring and control system is designed,in which STM32 is used as the main control chip and sensors are used to collect the environmental parameters such as temperature and humidity,light intensity,CO_(2)and TVOC concentration,and compared with the set numerical threshold,to decide whether to open the corresponding feedback compensation module to ensure that the parameters in the environment data in a relatively stable state,and then through the wireless module to send data to the host computer,at the same time,the host computer can send control commands to the slave computer to realize the closed-loop control of the whole environment.After testing:the current environment of the values tend to be stable,in good condition,the temperature,humidity,light intensity,CO_(2)concentration and TVOC concentration detection and control,the basic design requirements.
