摘 要

随着我国经济的迅速发展，工业化进程的加快，在建工程项目增多，雾霾、扬尘等污染也逐步成为影响国家生态环境的主要因素。建筑工地扬尘污染物为PM2.5，是城市雾霾天气和区域扬尘污染的主要来源之一。各级政府越来越重视建筑工地扬尘污染的控制，要求建筑工地配备扬尘污染监测系统。国内现有的施工扬尘污染监测方法一般由扬尘颗粒污染物监测仪组成，主要分布在在建工程围挡的四周和出入口处，其监测数据通过物联网实时反馈给政府监管部门，但监测效果受天气因素影响往往误差较大，监测周期长，难以为监管部门提供准确便捷的扬尘污染监测方法。因此，有必要探索一种可视化程度高、施工扬尘监测识别结果可信的扬尘监测并实时进行处理方法，对提高政府监管部门监测施工扬尘污染能力，帮助控制扬尘污染扩散具有一定的理论意义和应用价值。

论文分析了建筑工地扬尘污染特征，总结了施工扬尘的来源，以在建工地场地内的传感器监测数据来源做扬尘污染监测分析;根据监测的数据自动控制水泵进行工作，从而实现降尘，且可以将检测的数据通过蓝牙传输到手机端，通过手机端可以控制水泵进行工作。

Abstract

With the rapid development of Chinese economy, the acceleration of industrialization and the increase of construction projects, haze, dust and other pollution gradually become the main factors affecting national ecological environment. The construction site dust pollutant is PM2.5, which is one of the main sources of urban haze weather and regional dust pollution. Governments at all levels pay more and more attention to dust pollution control at construction sites and require construction sites to be equipped with dust pollution monitoring systems. The existing construction dust pollution monitoring methods in China generally consist of dust particle pollutant monitoring instruments, which are mainly distributed around the enclosure and at the entrance and exit of construction projects under construction. The monitoring data are fed back to the government regulatory authorities in real time through the Internet of Things. However, the monitoring effect is affected by weather factors, and the monitoring period is long. It is difficult to provide accurate and convenient monitoring methods for dust pollution for regulatory authorities. Therefore, it is necessary to explore a dust monitoring and real-time processing method with high visualization degree and reliable construction dust monitoring and identification results, which has certain theoretical significance and application value for improving the ability of government supervision departments to monitor construction dust pollution and help control the diffusion of dust pollution.

This paper analyzes the characteristics of construction site dust pollution, summarizes the sources of construction dust, and analyzes the dust pollution monitoring data from sensors in the construction site. According to the monitoring data, the water pump can be automatically controlled to work, so as to realize dust removal. Moreover, the detected data can be transmitted to the mobile phone through Bluetooth, through which the water pump can be controlled to work.

Key words: construction dust reduction; PM2.5; Water pump; Measurement and control; bluetooth
