Problems solved by technology

[0002] At present, due to the frequent occurrence of smog and haze weather, the air pollution is serious. With the deterioration of air quality, we pay more and more attention to health, especially the gas substances harmful to human body, and gradually carry out effective monitoring and treatment. The ambient air quality Monitoring is developed along with the increasingly serious air pollution. In view of the current situation, the atmospheric environment monitoring system based on big data is used to monitor the temperature, humidity, PM10, formaldehyde, carbon dioxide, sulfur dioxide, nitric oxide, etc. of the atmospheric environment. Among them, the output signal of the PM10 acquisition module is transmitted to the control terminal of the atmospheric environment monitoring system through the analog signal transmission channel, and the analog signal is prone to attenuation and frequency hopping during the transmission process, resulting in the atmospheric environment monitoring system based on big data.
