Atmospheric environment monitoring system based on big data

Abstract

The invention discloses an atmospheric environment monitoring system based on big data. The atmospheric environment monitoring system includes a frequency collection circuit, detection calibration circuits and a filter transmitting circuit; a signal frequency of a simulated signal transmission channel input end is collected by the frequency collection circuit; a disturbing signal filter circuit composed of an operational amplifier AR2, an operational amplifier AR3 and a capacitor C4 is used by a first circuit of the detection calibration circuits to filter out disturbing signals; a triode Q5 is used by a second circuit of the detection calibration circuits to detect abnormal high level signals, and at the same time, an amplitude limiting circuit composed of a diode D3 and a diode D4 is used to limit signals; and finally, a signal conduction loss is decreased by the two circuit signals through a push-pull circuit composed of a triode Q3 and a triode Q4. According to the atmospheric environment monitoring system based on the big data, a filter circuit composed of an inductance L3, a capacitor C10 and a capacitor C11 is used by the filter transmitting circuit to filter out signals, sothe accuracy of corrected signals is ensured, the reliability of terminal error correction controlled by the atmospheric environment monitoring system is improved.

Description

technical field [0001] The invention relates to the field of circuit technology, in particular to an atmospheric environment monitoring system based on big data. Background technique [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 t...

[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.
