Problems solved by technology
[0006] Since the environmental protection department has carried out strict monitoring of the ambient atmosphere in various places, the problem of falsification of monitoring data has repeatedly emerged in some places, such as changing the monitoring point. Since the existing atmospheric sampling equipment does not have the positioning function, if the equipment has The positioning function can well prevent the falsification of monitoring data caused by changing the monitoring point

The invention discloses a dual-channel atmospheric sampling instrument. The dual-channel atmospheric sampling instrument comprises a shell, an air collection system, a dust collection system and a control system. The control system comprises a first flow sensing module, a second flow sensing module, a central processing module and a wireless communication module. The first flow sensing module is arranged at an outlet of a first air pump and used for detecting air flow rate and then feeding back to the central processing module, and the central processing module controls operation power of the first air pump according to feedback information. The second flow sensing module is arranged at an outlet of a second air pump and used for detecting air flow rate and then feeding back to the central processing module, and the central processing module controls operation power of the second air pump according to feedback information. The central processing module sends operating state information of the instrument to a far-end computer / mobile terminal through the wireless communication module. The dual-channel atmospheric sampling instrument realizes simultaneous collection of dust and air.
Description
technical field [0001] The invention relates to the field of atmospheric sampling devices, in particular to a dual-channel atmospheric sampling instrument capable of simultaneously collecting dust and gas. Background technique [0002] With the process of human industrialization, environmental problems are becoming more and more serious. Industrial production emits a large amount of waste gas, and the content of harmful gases in the air continues to increase, which has brought serious harm to people's health. [0003] Meteorologists and medical experts believe that hazy weather caused by fine particles is even more harmful to human health than sandstorms. Particles with a particle size of 10 microns or more will be kept out of the human nose; particles with a particle size between 2.5 microns and 10 microns can enter the upper respiratory tract, but some of them can be excreted through sputum, etc. The internal fluff blocks it, which is relatively less harmful to human hea...
