Dust monitoring method and system based on narrowband internet of things

Abstract

The invention provides a dust monitoring method and system based on a narrowband internet of things, and belongs to the technical field of dust monitoring. By adoption of the apparatus and method provided by the invention, the intelligent collection and analysis of dust concentration data of tens of thousands of monitoring target locations within a large monitoring range can be realized, measurement results are finally output to find the target monitoring position where the dust concentration exceeds a safety range and trigger the alarm, meanwhile alarm information is fed back to a user, and the alarm information comprises the position of the target detection point that the user needs to process, the dust concentration data of the target monitoring point and the index beyond the normal range. According to the alarm information, the user can take corresponding measures to deal with each monitoring point in time to avoid unnecessary damage caused by dust explosion or to avoid serious environmental impact caused by the dust.

Description

【Technical field】 [0001] The invention relates to the technical field of dust monitoring, in particular to a dust monitoring method and system based on narrowband Internet of Things. 【Background technique】 [0002] Dust refers to solid particles suspended in the air. It is customary to have many names for dust, such as dust, dust, smoke, mine dust, sand dust, powder, etc. These terms have no obvious boundaries. The International Organization for Standardization stipulates that suspended solids with a particle size of less than 75 μm are defined as dust. The presence of dust in the atmosphere is one of the main reasons for maintaining the temperature of the earth. Too much or too little dust in the atmosphere will have a catastrophic effect on the environment. But in life and work, productive dust is the natural enemy of human health and the main cause of various diseases. [0003] With the improvement of people's living standards, people's security awareness is getting st...

Problems solved by technology

[0005] At present, although there have been great improvements in the monitoring and control of dust, there are still many small powder production plants (such as flour mills, cement factories), coal mines, grain depots, etc. that have not been paid attention to, and dust explosion accidents still happens frequently

Moreover, most of the instruments used to monitor dust are manually read the data, the data is not read in time, and the response is not timely is also an important factor causing dust explosion
