Problems solved by technology

[0002] Particulate matter in the air includes PM2.5, PM10, and TSP. The concentration of particulate matter pollution is an important indicator of air quality. For the monitoring of particulate matter concentration in the air, most of the data collected at fixed time intervals are compared with a fixed threshold. Yes, if the concentration of particulate matter is detected to be greater than the threshold at a certain moment, an alarm will be issued, but the content of particulate matter in the air will last for a period of time. If the above method is used, multiple alarms will be generated during the period of time when the concentration of particulate matter continues , a large amount of invalid alarm information will be generated. If the concentration of particle pollutants continues to increase after the alarm, it will not be possible to carry out
[0003] Dust suppression measures need to be taken after each alarm, such as spraying water, but for the situation of long duration and high particle concentration, dust suppression measures cannot play a good role, wasting water resources

specific Embodiment 1

[0054] A method for monitoring particle pollution in an air environment of the present invention, such as figure 1 , 2 shown, including the following steps:

[0055] S1, start;

[0056] S2. Collect real-time data on particulate matter pollution in the air environment;

[0057] S3. Comparing the real-time data with the pollution threshold to obtain a comparison result;

[0058] S4. When the real-time data is greater than the pollution threshold, query whether there is an alarm message, if there is an alarm message, update the alarm time, if not, create an alarm message;

[0059] S5. Real-time acquisition of published data on particle pollution in the air environment from national stations;

[0060] S6. When the real-time data is greater than the published data, calculate the warning classification;

[0061] S7, issuing warnings of different levels;

[0062] S8, end.

[0063] In a specific embodiment of the present application, the monitoring points are fixed, and the rea...

specific Embodiment 2

[0103] A monitoring device for particle pollution in the air environment, including a particle pollution detector in the air environment, a data processing center, a public data collection device, and an alarm device. The particle pollution detector in the air environment is used to detect particles in the air environment at the monitoring point Real-time pollution data and transmit it to the data processing center; the open data collection device is used to collect the published data of particulate matter pollution in the air environment of the national station and transmit it to the data processing center; the data processing center will collect the real-time pollution data of particulate matter in the air environment and Compare the pollution threshold. When connecting 50 real-time pollution data greater than the pollution threshold, check whether there is an alarm event. If so, update the time of the alarm event. If not, create a new alarm event to avoid missing and over-rep...

Abstract

The invention discloses a method and equipment for monitoring particulate matter pollution in an air environment. The monitoring method comprises the following steps: collecting real-time data of particulate matter pollution in the air environment; comparing the real-time data with a pollution threshold value; when the real-time data is larger than the pollution threshold value, whether alarm information exists or not is inquired, if yes, the alarm time is updated, and if not, the alarm information is created; and when the real-time data is greater than particulate matter pollution published data in the national station air environment, calculating early warning grades and giving an alarm. By comparing multiple continuous real-time data with the threshold value and inquiring whether alarminformation exists or not and whether the alarm information is larger than published data or not, the alarm accuracy is ensured from multiple aspects, excessive alarm and missing alarm are avoided, and accurate alarm of pollution is achieved. The equipment provided by the invention is used for monitoring and alarming pollution.
