Biological aerosol early warning system

Abstract

The invention discloses a biological aerosol early warning system, which comprises a biological aerosol early warning configuration module used for planning and configuring an early warning algorithm;a biological aerosol early warning module which is in data connection with the biological aerosol early warning configuration module and is used for extracting a background, analyzing biological characteristics, removing invalid samples, identifying biological characteristics of the samples and outputting an early warning signal; a biological aerosol collection module which is used for transmitting the collected data to the biological aerosol early warning module; a typical biological aerosol characteristic database which comprises characterization information of characteristic biological aerosol; an interferent feature database which comprises a plurality of interferent feature information; a biological aerosol early-warning anti-interference module which is in data connection with the interferent characteristic database and the biological aerosol early-warning module and is used for analyzing and identifying interferent characteristics and distinguishing interferents to provide interference influence factors for the biological aerosol early-warning module; and an early warning signal output unit which is in data connection with the biological aerosol early warning module.

Description

technical field [0001] The invention relates to the field of bioaerosol detection, in particular to a bioaerosol early warning system, and more specifically to a bioaerosol early warning system with anti-interference capability. Background technique [0002] The bioaerosol monitoring and early warning device is a device that monitors bioaerosols in real time by detecting bioaerosol particles excited in the laser beam to induce fluorescence signals, and can issue alarms according to changes in bioaerosol concentrations. The invention patent "a single light source bioaerosol particle detection device" published on December 28, 2011 with the application number 201110129408.5 provides a continuous photobioaerosol detection device, which uses a continuous light laser light source and A set of optical path system simultaneously excites particle scattered light and induced fluorescence, which can simultaneously analyze and monitor the particle size and biological characteristics of...

AI Technical Summary

Problems solved by technology

The early warning method with a fixed early warning threshold is adopted. If the set early warning threshold is too high, there will be a problem of missing early warning that no early warning signal will be issued even if bioaerosol is released; otherwise, there will be a problem of frequent early warning.

In addition, the bioaerosol concentration will also be interfered by disturbances such as smog, pollen, and dust. If there is no correct anti-interference method and algorithm to eliminate them, it may cause false alarms due to the interference of disturbances. Therefore, these early warnings Devices and methods cannot meet the needs of actual combat applications
