The invention discloses a detection system for components of atmospheric particles based on an ultrasonic detection technology in the technical field of atmospheric detection. The detection system comprises an ultrasonic generation unit, wherein the output end of the ultrasonic generation unit is electrically connected with the input end of an ultrasonic receiving unit; the output end of the ultrasonic receiving unit is electrically connected with the output end of a signal amplifying unit; a single chip microcomputer is respectively and electrically connected with an analysis unit and an upper computer in a two-way manner; the output end of the upper computer is electrically connected with the input end of a data storage unit; and the propagation velocity of ultrasonic waves is calculated according to the propagation time of the ultrasonic waves received by the ultrasonic receiving unit, and then the components of the particles in the atmosphere are calculated out according to the sound velocity, the temperature and the humidity. The detection system disclosed by the invention has the advantages that amplification and reshaping of the ultrasonic waves by signals are realized in the process of ultrasonic-wave reception, the accuracy of the received signals is guaranteed, and remote transmission of detection data and detection results is also realized.
Description
technical field [0001] The invention relates to the technical field of atmospheric detection, in particular to an atmospheric particle composition detection system based on ultrasonic detection technology. Background technique [0002] Atmospheric particulate matter is a general term for various solid and liquid particulate matter present in the atmosphere. Various particulate substances are uniformly dispersed in the air to form a relatively stable and bulky suspension system, that is, an aerosol system, so atmospheric particles are also called atmospheric aerosols. With the rapid growth of my country's economy and the continuous acceleration of urbanization, atmospheric particulate matter is currently the primary pollutant in most cities in my country, and haze pollution has shown a significant upward trend. At present, the air pollution of urban agglomerations in my country is a special type of air pollution that coexists with soot and vehicle exhaust pollution. It has o...
