基于SCADA 的物联网大气环境监测系统设计

为解决传统监测系统无法做到精确、实时地监控各地区大气环境数据的问题, 设计了基于SCADA(Supervisory Control And Data Acquisition)系统, 集组态软件、计算机和数据库技术于一体的物联网大气环境监测系统。该系统使用便携式气体检测仪作为下位机对大气污染物浓度进行采集, 利用组态软件搭建中央监控平台对采集数据进行接收处理与分析。该系统实现了下位机接收数据, 服务器存储数据, 并能实时进行数据监测及历史数据查询。实验结果显示, 该系统既可实时监控监测节点的大气环境变化, 又可实现监测节点的历史数据查询, 生成历史报表, 具有采集数据、存储数据及气体浓度预警的功能。解决了传统监测系统存在的监测范围无法细化、监测数据无法实时更新与发布的问题, 为更加方便、实时、高效地监测大气环境提供了技术保障。

Design of Internet of Things Environment Detection System Based on SCADA

In order to solve the problem that the traditional monitoring mode can not accurately and real-time monitor the atmospheric environment data of various regions, an air environment monitoring system of Internet of things based on SCADA ( Supervisory Control And Data Acquisition ) system is designed. The system uses a portable gas monitor as the slave computer to collect atmospheric pollutant concentrations, uses configuration software to build a central monitoring platform to collecting and analyzing thereceived data. The system realizes receiving data from the slavecomputer, realizes data storage with the server, and realizes real-time data monitoring and historical data inquiry. The system can monitor the changes of atmospheric environment of nodes in real time, and can also query the historical data of monitoring nodes and generate historical reports. It has the functions of collecting data, storing data and pre-warning of gas concentration. The system solves the problems that the traditional monitoring system can not refine the monitoring scope and the monitoring data can not be updated and released in real time, and it provides technical support for more convenient, real-time and efficient monitoring of the atmospheric environment.
