With the development of society and the vigorous advancement of urbanization, urban dust has also become one of the important sources of PM2.5. Currently, the main methods for monitoring dust are manual sampling and analysis. The detection efficiency is low and a lot of manpower and material resources are wasted. Construction site dust and noise real-time monitoring system BYQL-YZ is a set of construction site environmental monitoring noise dust terminal equipment that meets the relevant standards of GB3096-2008 "Acoustic Environmental Quality Standard" and GB3095-2012 "Ambient Air Quality Standard". The monitored data indicators include dust concentration, noise index, video images and related meteorological parameters. Through the Internet of Things and cloud computing technology, real-time, remote, and automatic monitoring of particle concentration and on-site video and image collection are achieved; data is transmitted through the network and can be accessed on multiple terminals such as computers, mobile phones, and tablets.
Shenzhen Biye Trinidad Technology Co., Ltd.
The system is designed based on the requirements for monitoring and management of dust pollution in urban construction sites. The technical characteristics and advantages are mainly reflected in the following points:
(1) Monitoring terminal system The system integrates multiple environmental parameters such as TSP, PM10, PM2.5, temperature, humidity, wind direction and wind speed, atmospheric pressure, rainfall, etc., and continuously monitors online 24 hours a day, and provides air quality data on the construction site around the clock. The monitoring equipment can be automatically started when the alarm value is exceeded, with the characteristics of multi-parameter, real-time, and intelligent;
(2) Transmit and transmit data through the three major networks of sensor networks, wireless networks, and the Internet, and update real-time monitoring data quickly and conveniently;
(3) The cloud computing-based data center platform gathers monitoring data in different regions and at different periods, and has a large amount of storage space. It can carry out multi-dimensional and multi-temporal data statistical analysis, which is convenient for the management part to carry out work in an orderly manner, and is also for the establishment of The construction site environmental pollution control standards accumulate data to promote long-term management of air pollution.
(4) The whole system adopts free modular combination, according to the need of unorganized pollution monitoring, different monitoring items can be flexibly added or reduced. At the same time, the free modular combination can be used at any time if the core sensor fails and does not need to be repaired. The sensor is replaced without affecting the normal operation of the whole equipment, which solves the problem of time-consuming and cost-consuming returning the whole machine to the factory when the traditional equipment fails

BYQL-YZ construction site dust and noise online monitoring system is an automatic construction site dust and noise monitoring station specially developed for environmental monitoring. The dust and noise monitor mainly installed on the construction site, the data transmission is mainly composed of: GPRS data transmission network, data receiving server, client (server and client can be the same computer).
The BYQL-YZ construction site dust and noise online monitoring system sends the monitored dust concentration data to the server receiving the data through the GPRS transmission network through the Internet, and automatically saves and writes the data into the database. The client can view the data through the browser Wait. Customers can monitor the online monitoring equipment for dust and noise on the construction site by receiving software and SMS control.
