In the construction site, a large amount of dust will be generated due to the activities of construction personnel or the operation of machinery. This dust will be scattered into the air and move with the flow of air, and finally become fine particles that are easily inhaled. These particles not only pollute the air and reduce visibility, but also carry a large amount of carbon, hydrogen, sulfur, chlorine, fluorine and other heavy metals and bacterial viruses. Once inhaled by the human body, it will endanger people’s health. The dust monitoring system consists of dust monitoring equipment and a remote monitoring cloud platform. It has data acquisition, data analysis and over-limit alarm functions, and can be used for 24-hour long-term outdoor monitoring.
What is a dust monitoring system?
The dust monitoring system is based on the Internet of Things and artificial intelligence technology, collects the data monitored by sensors (PM2.5, PM10, noise, wind speed, wind direction, wind power, atmospheric pressure, air temperature and humidity, TSP, etc.) and displays it in real-time through the LED screen. Then upload it to a professional platform for PC or APP check, which is convenient for remote monitoring of the on-site environment and timely decision-making, can realize accurate monitoring of dust and prevent dust pollution.
The composition of dust monitoring system
Detection part
Dust monitoring: It consists of PM2.5 sensor and PM10 sensor. The dust is continuously and automatically monitored by sensors, data is collected every minute, and uploaded to the server in real time for background program statistics and analysis.
Noise monitoring: complete outdoor noise collection composed of noise sensors, providing reliable guarantee for the sensor’s outdoor monitoring safety and data accuracy
Meteorological monitoring: It is composed of a wind speed sensor, wind direction sensor, and solar radiation shield, which provides meteorological parameter guarantee for the later analysis of dust monitoring data, especially scientific prediction and alarm on the movement trend of dust through wind direction.
Data processing
The data processing unit composed of the collection host is the center of the dust monitoring system, which collects and stores the data monitored by the sensor. Then perform analysis and processing according to statistical requirements, upload the processed data to the cloud platform, and control the localized display of parameters to realize the fusion of environmental parameters and video surveillance images
Data Display
The real-time monitoring data is displayed on-site by an external LED display screen, which serves as a warning to construction units and residents, and can control and reduce pollution in a timely manner when the upper limit of noise or dust is reached.
Data platform
Generally, it consists of a cloud platform for online dust monitoring.
Two types of dust monitoring equipment
The dust monitoring equipment used in different places is also different. According to different working principles, it can be roughly divided into two types: pump-suction dust monitoring equipment and diffusion-type dust monitoring equipment.
Pump suction dust monitoring equipment
The pump suction dust monitoring equipment adopts the principle of laser scattering, which is more comprehensive than the diffusion dust monitoring equipment. It uses a pneumatic flow pump as power, so that large particles of dust will not adhere to the inside of the cavity, and the measurement cavity also adopts a straight-through structure, which will not cause dust accumulation after long-term use, good stability, and data consistency. much better. The pump suction dust monitoring equipment is equipped with an electric control box, which is equipped with dehumidification equipment, which can filter water vapor and effectively prevent false alarms.
This dust monitoring device is designed for the outdoors. The rugged weatherproof housing helps maintain peak performance in harsh conditions and can be placed for monitoring in open areas or mounted on a pole for use.
Measurable: PM2.5, PM10, noise, temperature, humidity, wind speed, wind direction, wind, TSP, atmospheric pressure, CO, NO2, SO2, O3
Features:
- This dust monitoring device has a pumping function, adopts a high-precision PM (PM2.5/PM10/TSP) sensor, and has a filter and dehumidification function for accurate measurement.
- The high-quality waterproof case protects the circuit components from environmental corrosion, can work normally in harsh environments, and has a long service life.
- The data can be uploaded to the monitoring software platform through GPRS/4G, and the host can connect an external LED screen (54cm*102cm) to display the current value information in real time.
Diffusion dust monitoring equipment
This diffuse dust monitoring device also adopts the principle of laser scattering, uses a fan as power, and has low power consumption. It is installed on a pole, which can effectively resist the windy weather. High-intensity waterproof LED display with clear values and real-time display of current environmental conditions.
The bracket of the diffuse dust monitoring equipment is available with single beam and double beam
Measurable: PM2.5, PM10, noise, temperature, humidity, wind speed, wind direction, wind, TSP, atmospheric pressure
Features
- The device has 1 channel solar radiation shield (temperature, humidity, noise, PM2.5, PM10, air pressure, TSP) acquisition, 1 channel wind speed acquisition, 1 channel wind direction acquisition, 1 channel four gas acquisition, 1 relay output (the default can be connected to the scene Secondary relay control fog cannon), 1 channel 485 slave output
- The data can be uploaded to the monitoring software platform through GPRS/4G. At the same time, the host can connect an external LED screen (54cm*102cm) to display the current value information in real time
- This dust monitoring device uses the principle of laser scattering, the fan is used as the power, and the built-in insect-proof net will not cause inaccurate data measurement due to small insects. Measuring range 0-1000ug/m3
Advantages of dust monitoring systems
1. Automatic collection
Dust monitoring equipment has built-in high-precision sensors for PM10, PM2.5, TSP, wind speed, wind direction and other monitoring equipment, which can accurately monitor the real-time values of various monitoring elements in the construction environment, with high data measurement accuracy and small errors. Automatic 24-hour uninterrupted work.
2. Data Analysis
The cloud platform is the monitoring terminal of the online dust monitoring system. It can receive all the data uploaded by the monitoring station, display the real-time data on the platform interface through numbers or dashboards, and automatically store historical data, analyze the data and display it in the form of a curve. Users can view and download historical data in stages according to their needs.
3. Remote monitoring
In addition to the cloud platform provided by our company, which can be viewed and monitored on the computer, it also supports various terminal login methods such as mobile APP and WeChat public account, which is convenient for users to receive the data uploaded by the monitoring equipment in real time; various parameters can also be directly performed on the terminal. settings to achieve the purpose of remote automatic monitoring.
4. Over-limit alarm and intelligent linkage
When the real-time data monitored by the monitoring station exceeds the set limit, the system will promptly send alarm information to the staff in the form of text messages, phone calls, and WeChat. If the value of PM2.5 exceeds the dust start value, the system will send a linkage command to the relay to enable it to intelligently turn on spray systems such as fog cannons to reduce the content of particulate matter in the air.
