A kind of bioaerosol laser monitoring early warning and identification device, including monitoring means, sampling unit, discriminating unit and overall control unit；The described bioaerosol in monitoring means monitoring of environmental and distinguish the abiotic particle in air and biomone, obtains biomone concentration, and is transferred to described overall control unit；Described overall control unit controls the duty of described monitoring means, sampling unit and discriminating unit respectively, when the bio-aerosol concentration that monitoring means monitors reaches threshold value of warning, overall control unit sends early warning signal, triggers described sampling unit simultaneously and starts to gather bioaerosol sample.This utility model can accurately identify the kind of bioaerosol, quickly differentiates the kind of biomone, has the advantage that the discriminating time is short, accuracy is high. |
