Dust online monitoring system

Overview:

With the increasing demand for environmental governance in our country, PM2.5 has become an important indicator for environmental monitoring, and dust in the air, as an important component affecting PM2.5 indicators, has also become the object of monitoring by environmental protection departments at all levels. The current main methods for detecting dust are manual sampling and analysis, which have low detection efficiency and waste a lot of manpower and resources. Our company utilizes wireless sensor technology and laser dust testing equipment to improve air quality. Our self-developed all-weather outdoor dust monitoring system can not only achieve dust monitoring, but also monitor environmental factors such as PM2.5, PM10, PM1.0, TSP, noise, environmental temperature, environmental humidity, wind speed, and direction. The test data of each test point is directly uploaded to the monitoring background through wireless communication, Greatly saves monitoring costs for environmental protection departments and improves monitoring efficiency.

Application industry:

Mainly suitable for construction sites, demolition sites, coal mines, industrial parks, communities, urban environments, residential communities, etc.

System composition:

This system consists of a data collector, sensors, video monitoring system, wireless transmission system, backend data processing system, and information monitoring management platform. The monitoring sub station integrates various functions such as atmospheric PM2.5 and PM10 monitoring, environmental temperature, humidity, wind speed and direction monitoring, noise monitoring, video monitoring, and video capture (optional) of pollutants exceeding standards, as well as toxic and harmful gas monitoring (optional); A data platform is a networked platform with internet architecture, which has monitoring functions for various sub stations and various functions such as alarm processing, recording, querying, statistics, and report output for data. The system can also be linked with various pollution control devices to achieve automatic control.

Product features:

1. Implemented real-time online monitoring 24 hours a day, 24 hours a day.

2. To provide accurate particle concentration information, multiple sensors can be connected and remotely transmitted to a large display screen.

3. Alarm management has been set up, sending text messages to designated mobile phones after exceeding the limit, timely warning, and improving the effectiveness of real-time monitoring.

4. Temporary faults in external power and communication systems do not affect data collection, and delayed data can be automatically downloaded after communication is restored; Permanent power outage does not lose collected and stored data.

5. Support real-time display of data for various sizes of color LCD and LED outdoor displays. (Outdoor display screens can be customized according to customer needs)

6. Implement data storage management, graphical display of monitoring point data, curve analysis, statistics of exceeding limit and exceeding limit alarms, etc., providing decision-making basis for regulatory authorities.
