On line monitoring system for dust and noise at construction sites in Yunnan

  Yunnan on-line monitoring system for construction site dust and noise recently, all provinces and cities in China have begun to make efforts to monitor and control the environment, especially in the monitoring and control of construction site dust
As we all know, in the past two years, the increasingly serious air pollution problem has not only seriously endangered the health of the public, but also introduced topics to thousands of households through news media and social networks, which has become one of the common hot issues among the people

The development of the country is to make the people live a good life
If the development is based on the premise of damaging the health of the people, what is the significance of development? Therefore, according to the relevant national policies and instructions, under the guidance of government units at all levels, various environmental monitoring and governance work have been carried out one after another

In the city, the main work object is the construction site
This paper will also answer why we choose to monitor and control the dust on the construction site

Fugitive dust, also known as floating dust, mainly refers to inhalable particulate matter PM10, which refers to a kind of fine particulate matter that can be inhaled into the respiratory system through the mouth and nose
When people are exposed to the environment with dust PM10 exceeding the standard for a long time, they will inhale a large amount of particulate matter, which will lead to various diseases and great harm over time

In the urban environment, the main place for man-made dust is the construction site, so it is necessary to monitor and control the dust on the construction site

Especially for large construction sites, due to their large construction scope, long construction time and more dust PM10, the hazards are particularly great
This will not only have an impact on the surrounding environment of the construction site, but also have a serious impact on the health status of the site staff

On the one hand, through the monitoring and management of PM10 on the construction site, all construction on the construction site meets the environmental protection standards; On the other hand, through monitoring and management, it is ensured that the site staff and the surrounding people can reduce the harm of the air environment to the body as much as possible

Dust introduction
Fugitive dust is an open source of pollution caused by wind, man-made and other driving dust on the ground to enter the atmosphere
It is an important component of total suspended particles in the ambient air
During the transportation and processing of the powder, the flow air caused by the induced air flow, indoor ventilation and the air flow generated by the rotation of the moving parts of the equipment will first separate the fine dust in the powder from the powder and then cause the diffusion of the powder due to the indoor air flow, thus completing the process from dust generation to diffusion

Fugitive dust is divided into several types, mainly including road fugitive dust, construction fugitive dust, yard fugitive dust, etc
according to the relevant introduction, fugitive dust is an unorganized pollution source with a large prevention and control coefficient, which is a key subject of the 13th five year plan of the Ministry of environmental protection of the people's Republic of China
Therefore, it is very necessary to carry out fugitive dust control, and fine monitoring and fugitive dust management become the top priority
national policy
The management department issued the ten measures of the action plan of the air pollution prevention and control law to promote the improvement of air quality, which is the action guide for the prevention and control of domestic air pollution at present and in the future
The action plan has identified ten specific measures, the first of which is to comprehensively control urban dust and cooking fume pollution

On line monitoring system for dust and noise at construction sites in Yunnan
Product introduction of dust (noise) online monitor
The on-line dust (noise) monitoring system is a special monitoring system independently developed for dust and noise environmental monitoring in urban construction, road, pipeline construction, demolition construction, enterprise yard and other occasions
Using advanced technologies such as Internet of things perception, data wireless communication, database, geographic information system and video, integrating data collection, transmission, multi-dimensional data display and application, real-time monitoring of dust and noise pollution data of enterprises, combined with video monitoring, alarm pictures, audio multi-dimensional data supporting analysis, to realize dust supervision informatization, and jointly provide digital supervision means for environmental protection, urban construction, transportation and other regulatory departments, Meet joint needs

Dust (noise) online monitor function:
1
Real time online dust monitoring, with automatic control and audible and visual alarm functions, will automatically start one or more set automatic control devices when the detection value reaches the set upper limit
For example, when the particle value reaches the set upper limit, it will automatically start the start of the (fog gun) spray system, take atomization spray dust reduction measures for the on-site environment, and automatically close the spray system when the particle value reaches the set lower limit; Achieve the purpose of intelligent automatic control;
2
According to the requirements of on-site dust removal and construction water, realize the functions of intelligent timing spraying and water supply;
3
The system is automatically controlled by an intelligent controller, which is easy to operate, intelligent to reduce dust, and saves manpower and material resources;
4
The product has a variety of protection functions such as short circuit, overcurrent, overvoltage, overheating, overload, etc
in case of any fault in the system operation, it will automatically stop working and alarm output;
5
The product has self checking function, fault judgment, fault memory, fault prompt and other functions;
6
It has manual and automatic switching functions to ensure continuous operation of the equipment in case of control system failure;
8
With “ Internet + construction dust control ” The management platform provides users with real-time and effective dust control data;
9
In addition to the effect of dust reduction, the system can also cool the construction site
In case of fire accidents, the sprinkler system can be adjusted to increase the amount of sprinkler, which can cooperate with the fire fighting;
10
It has led special interface and supports monochrome, two-color and full-color LED display screens of various sizes;
11
