基于labview的综合楼宇环境监测系统设计

Design of the environment monitoring system for integrated building based on LabVIEW

多年工业的发展带来了大气环境污染严重。大气污染不仅会影响人们的正常生活,而且还引发了一系列的疾病.由于人们的生活和工作基本都是在室内,因此系统以民生相关的室内环境参数作为采集对像,实现了基于LabVIEW的多层建筑物室内外空气质量在线监测。监测对象包含了空气中的二氧化碳、PM2.5、温湿度、VOC等。分布式节点将多传感器数据进行限幅均值滤波处理后,通过RS485总线传输到上位机,最终实现实时监测。系统还通过ZigBee技术实现了室外空气质量数据采集,根据室内外数据对比可以为室内空气净化控制提供有效的支撑。

The development of industry for many years has brought serious pollution to the air environment.Air pollution will not only affect people＇s normal life,but also trigger a series of diseases.Due to people＇s life and work are basically indoors,the system takes the indoor environment parameters related to people＇s livelihood as the collected objects,and realizes the online monitoring of indoor and outdoor air quality of multi-storey buildings based on LabVIEW.The monitoring object contains carbon dioxide,PM2.5,temperature and humidity,VOC,etc.in the air.The multi sensor data which is processed via amplitude-limit fitltering and mean filtering by distributed nodes will be transmitted to the upper computer through RS485 bus,and will be monitored in real time finally.The system also realizes the collection of outdoor air quality data through ZigBee technology.It can provide effective support for indoor air purification control according to the comparison of indoor and outdoor data.
