Air quality detection equipment

Abstract

The invention provides air quality detection equipment. The air quality detection equipment comprises a simulation sub unit, a multiplexer, an analog-digital conversion sub unit and a digital sub unit, wherein the simulation sub unit comprises a plurality of analog signal interfaces, and the analog sub unit is used for receiving, processing and sending analog signals; the multiplexer is connectedwith the analog signal interfaces, and is used for converting the multichannel input analog signal into a analog signal with one-channel output; the analog-digital conversion sub unit is connected with the multiplexer, and is used for carrying out analog-digital conversion on the analog signal output by the multiplexer; the digital sub unit is provided with a plurality of digital signal interfaces, at least one digital signal interface is connected with the analog-digital conversion sub unit, and the digital sub unit is used for receiving, processing and sending digital signals. According to the air quality detection equipment provided by the invention, the quantity of devices can be obviously reduced, and the economical efficiency of a circuit is improved while the performance of the circuit is guaranteed.

Description

technical field [0001] The present disclosure relates to the technical field of air quality detection, in particular to air quality detection equipment. Background technique [0002] In the 21st century, environmental problems have become more and more prominent with the rapid development of China's economy. Since the second decade of this century, this problem has gradually received the attention of the whole society. After years of continuous treatment, the air pollution situation has been greatly improved. my country's national standard is the lowest level for developing countries in the health guidelines of the World Health Organization (WHO). Even so, during the three years of monitoring PM2.5 in 74 major cities across the country, the cities that can meet the standard are the highest. 20%, only 4.1% at the lowest point, and 105.7% at the highest national average annual rate. The task of pollution prevention and control is still very heavy. The central government regar...
