The Design Of Construction Site Dust And Noise Monitoring System

With the acceleration of the process of urbanization in our country,the number of construction sites has continued to increase,and the dust generated by construction has become one of the important sources of air pollution.In addition,the noise generated by building construction not only affects people's normal life,but also has a negative impact on people's physiology and psychology.In this regard,national and local standards for the discharge of dust from construction and noise have been established,and strict management of dust and noise emissions has been implemented.Aiming at the current situation of single supervision,low management efficiency and poor real-time performance,an on-line monitoring system for dust and noise based on cloud computing was designed.The design consists of three parts: front-end data monitoring system,communication system and cloud server.The front-end data monitoring system consists of an embedded IPC and a laser particle concentration sensor,a noise sensor,an ultrasonic wind direction sensor,and a GPS positioning module.The embedded industrial control computer reads the data of each module through the serial port and uses C# language to write the front-end data monitoring software.The software realizes the functions of displaying,storing,querying,and uploading environmental data.The system supports various network communication methods such as 3G,4G,and broadband,and can be selected according to actual conditions.Currently,GPRS wireless communication module is selected as the front-end data monitoring system.The communication bridge between the cloud server and the cloud server.The GPRS module has the advantages of low cost,fast networking,and permanent online.The cloud server is selected as the proxy server of the system.Compared with the traditional server,the cloud server has high performance-price ratio,good stability,and responsiveness.With the advantages of high speed and so on,the cloud server software written in C# language is responsible for receiving real-time data uploaded by the data monitoring system and achieving the purpose of remote monitoring.The system adopts sensor technology,cloud computing technology and wireless communication technology to achieve real-time,automatic and comprehensive monitoring of environmental parameters such as dust and noise on construction sites,and improves the level of intelligence and intensification of construction site environmental management.The system has The following features:(1)The use of cloud computing technology to quickly build a server platform,without special purchase of server equipment,reducing the cost of equipment,making the system easy to promote;(2)front-end equipment,small size,easy installation,and equipped with satellite positioning module,can be used as The vehicle-mounted environmental monitoring system is used;(3)A custom dynamic communication protocol is used for data interaction between the front-end data monitoring system and the cloud server to solve the problem of large data traffic.For example,for a fixed monitoring site,satellite positioning information is sent only once.The equipment was installed near the monitoring station set up by the Environmental Protection Agency to conduct on-site monitoring and compared with the environmental conditions released on the day of the official release.The data obtained from the two tests were basically the same.Experiments have shown that this system meets actual monitoring needs and can be used to monitor environmental data such as dust and noise at construction sites.
