基于物联网的水源污染自动监测预警系统研究——以山洪灾害为例
|
摘要
水源污染的造成因素众多,山洪灾害是较为重要的原因之一。由于山洪灾害的不确定因素,使水源污染的监测预警难度增大,提出基于物联网的水源污染自动监测预警系统。根据预警系统的安装要求将水源污染监测预警系统设备进行安装,预警系统在监测时,首先统计近年来由山洪灾害引起的水源污染数据,利用模糊评价模型对水源污染数据进行风险等级的划分。采用临界雨量的计算方法对山洪灾害高发区临界雨量进行计算,将计算出的站点临界雨量与平均临界雨量相比较,通过比较结果来判断山洪灾害是否会发生,实现对由山洪灾害引起的水源污染的自动监测预警。
There are many causes of water pollution,and mountain torrents are one of the most important causes. Because of the uncertain factors of mountain torrents,it is more difficult to monitor and warn water pollution. An automatic monitoring and warning system of water pollution based on Internet of things is put forward. According to the installation requirements of the early warning system,the equipment of the water pollution monitoring and early warning system is installed. In the monitoring of the early warning system,first of all,the data of water pollution caused by mountain torrents in recent years are counted. The fuzzy evaluation model is used to classify the risk level of water source pollution data. The automatic monitoring and warning of water source pollution is converted to the early warning of mountain torrents,and the area with high risk level is selected as the Monitoring samples,according to the scale of rainfall classification,according to the monitoring samples of rainfall grades,using the critical rainfall calculation method to calculate the critical rainfall in high incidence areas of mountain torrents. By comparing the calculated critical rainfall with the average critical rainfall,we can judge whether the mountain flood disaster will occur or not,and realize the automatic monitoring and warning of water pollution caused by the mountain flood disaster.
